颗粒度对不同煤种可见光-近红外光谱的影响

煤炭是我国最主要的能源,在开采、运输、洗选加工、精煤储运等过程中都需要及时了解煤的成分、含量以及混矸程度,以便掌握和监控煤炭质量。目前,基于可见光-近红外反射光谱的煤炭原位测试技术已经成为一个研究热点。颗粒度是影响光谱特征的重要因素,开展颗粒度对不同煤种反射光谱特征的影响研究,对于深刻认识煤的光谱特征,进而提高煤光谱识别精度具有重要意义。为此,选取我国主要煤炭富集区（包括内蒙古乌海、新疆哈密、山西阳泉）的褐煤、烟煤、无烟煤为研究对象,利用SVC HR-1024光谱仪对不同颗粒度煤样的可见光-近红外光谱进行测试,分析了颗粒度对煤样光谱反射率的影响规律,以及颗粒度对于不同煤种光谱影响的差异。在此基础上,对实验现象背后的物理机理进行了分析讨论。研究表明,变质程度不同的煤反射光谱特征基本相似,即在可见光波段反射率较低且随波长增加出现缓慢下降趋势,在近红外波段快速上升。当煤样颗粒度>0.10 mm时,颗粒度大小对光谱特征的影响较小,煤样反射光谱特征随颗粒度变化规律不明显;当颗粒度<0.10 mm时,颗粒度对煤样的光谱影响增大,且影响主要体现在近红外波段的反射率光谱曲线的斜率大小,颗粒度越小,光谱反射率曲线斜率越大。0.10 mm颗粒度可作为颗粒度对煤的光谱特征影响的敏感界限。不同煤种可见光-近红外光谱曲线受颗粒度的影响程度不同,褐煤的影响最大,烟煤次之,无烟煤影响最小。实验表明,利用反射光谱进行煤质分析和煤种识别时需要考虑颗粒度的影响,同时,选择颗粒度小于0.10 mm的粉末状样品效果要好于大颗粒或块状样品。     

Laser absorption and fluorescence diagnostics of a plasma

Diagnostics of a near-surface laser plasma, the plasma of a strong-current pulse gaseous discharge in inert gases, nitrogen, and carbon dioxide under conditions of intense evaporation of the wall of the discharge chamber, the plasma of a discharge with a hollow cathode, and the active medium of an excimer laser was conducted by methods of intracavity laser spectroscopy and laser-induced fluorescence. The dynamic fields and absolute concentrations of atoms, ions, molecules and electrons, the plasma temperature, and the velocities of flows of particles were measured. The quantitative determination of the density of particles in the erosion laser flame prior to breakdown and the phenomena associated with the formation of molecules in the laser plasma received primary consideration.

Effect of the mode composition of laser radiation on the intracavity formation of periodic surface structures

We investigated the effect of the mode composition (longitudinal and transverse modes) of laser radiation on the basic parameters of the stroke pattern formed on a treated surface placed inside a laser cavity. We found that the contrast of the stroke pattern formed by a laser beam with a complex set of longitudinal modes depends, in the first place, on the width of the laser radiation spectrum and the laser cavity length and is virtually independent of the angle of rotation of the beam. In the region of small rotation angles the broadening of strokes caused by the effect of transverse modes becomes predominant. B. I.

Rotation of the light polarization plane by an ensemble of oriented linear associates: Model representations

In an “oriented gas” model expressions are obtained for the angle of nongyrotropic rotation of the polarization plane (NRPP) of transmitted light by an ensemble of oriented associates consisting of nongyrotropic molecules. The cluster character of the nongyrotropic rotation of the polarization plane and the dependence of its angle on the incident light polarization vector azimuth are noted, which distinguish linear and circular polarization effects. Measurement of linear dichroism by the angle of nongyrotropic rotation of the polarization plane with the use of commercial spectropolarimeters is theoretically justified.

The width of the rotational contour of vibrational and vibronic bands of complex molecules in the gas phase as a temperature indicator

From the independence of the contour of spectral density of the rotational (orientation) correlation function of a rigid molecular top of arbitrary symmetry on temperature in the frequency scale based on the reduced time of rotational orientation relaxation and from the near independence of the rotational contour of vibrational and vibronic absorption bands of dipole transitions in the same coordinates in a model of “regular diffusion” of the transition oscillator with a classically rotating rigid molecular top, it is suggested that it is possible to use the halfwidth of the contour for estimation of temperatures. Data are presented on the halfwidth of 48 contours of bands of A, B, and C types at this frequency for 12 compounds for a temperature range of from units to 500 degrees of absolute temperature measured experimentally and (for low temperatures) calculated by the quantum theory.

XRF与ICP-MS法在福建省安溪县和华安县的铁观音茶中元素含量测定的应用研究

安溪是铁观音茶的源产地,茶叶总产值每年数亿元,但不同品质的铁观音茶价格参差不齐,市场上存在以次充好的现象。福建省安溪县和华安县为铁观音主要的茶产地,两县市的茶叶产量市场占有率较高,地理位置毗邻,但茶叶品质和风味各有不同,造成茶叶市场的困扰。铁观音中微量元素种类和含量的检测,对产地的溯源具有重要的意义。采用X射线荧光光谱无标样半定量分析法(XRF)和微波消解/电感耦合等离子体质谱法(ICP-MS)对福建省主要茶产区安溪县(感德、西坪、祥华)和华安县(良村、华丰、仙都)的30份铁观音进行元素含量对比分析。XRF法检测出两县茶样中存在的元素种类有K, Ca, S, P, Mg, Al, Si, Cl, Fe, Mn, Rb, Zn, Na和Sr,但含量上存在一定的差异。根据XRF法检测结果进行快速、准确稀释茶样用于ICP-MS法对比测定金属元素,优化样品前处理方法以满足痕量检测要求。对比发现当测定Ca, Mg, Al, Fe, Mn和Zn金属元素时,相关性系数R²在0.824 8～0.892 8,趋势线斜率在0.806 0～0.944 9, XRF法和ICP-MS法的可...     

橄榄油的聚集荧光猝灭及吸收光谱特性的研究

素有“液体黄金”之称的橄榄油已成为健康食用油的代名词,不仅身价陡增,而且在非产地市场也已成为一种畅销油。在橄榄油检测技术中光谱法与其他技术相比具有快速、无损、无样品处理等优势而备受关注,而不同的光谱检测方法在检测的物质成分上各有侧重,例如红外光谱法侧重于脂肪酸含量的检测、拉曼光谱法侧重于分子的检测、荧光光谱法侧重于光敏物质的检测以及吸收光谱法侧重于光敏物质和不饱和脂肪酸的检测等。荧光及吸收光谱对光敏物质反应极其灵敏,而橄榄油富含叶绿素等光敏物质,因此荧光及吸收光谱成为一种鉴别橄榄油的有效技术手段。叶绿素是一种含有环卟啉结构的有机分子,该类分子结构具有吸光特性,且不同的叶绿素吸收光谱各异,其中绿色植物的叶绿素a含量最多。为深入研究叶绿素的吸收光谱及荧光特性在橄榄油鉴别中的应用,将特级初榨橄榄油中掺入不同比例的玉米油,已达到间接调控橄榄油中叶绿素含量的目的,测量不同掺伪比例橄榄油的荧光及吸收光谱并研究与叶绿素浓度的相关性,以此来研究叶绿素浓度与掺伪量对橄榄油吸收光谱及荧光特性的影响。取10份同批次的特级初榨橄榄油,将其中9份按照等比例稀释,并对10份样品按照掺伪量依次排序;依次采集这10份样品的荧光及吸收光谱,比较叶绿素浓度与掺伪量的相关性及对这两种光谱技术在橄榄油鉴别中的影响。随着叶绿素浓度的上升,荧光强度由弱变强,并在某一时刻后会出现荧光强度急剧减弱的现象,即聚集荧光猝灭。这种现象主要是由于叶绿素的环卟啉分子结构引起的分子间π-π作用,使未被激发的低能分子与高能分子堆叠在一起,能量的辐射跃迁（荧光）也转变为分子间的能量转移（热能交换）。对于吸收光谱,随着叶绿素浓度的上升,吸收光谱的强度也逐渐增强。橄榄油中叶绿素吸收的能量主要去向包括镁电子辐射跃迁产生荧光以及分子间热能交换两部分,而橄榄油的吸收光谱并未出现类似于聚集荧光猝灭的现象,且吸收光谱强度与掺伪浓度间存在近似线性相关的关系。结果表明：当聚集荧光猝灭出现时,叶绿素吸收的能量仍然与浓度呈线性相关,此时高、低能分子堆叠引起的热能交换效率提高。     

光栅-液晶复合结构太赫兹移相器

随着太赫兹技术及其应用的快速发展,各类太赫兹控制器件需求也随之增加,作为太赫兹系统重要器件之一,太赫兹波移相器成为当前研究热点。已有移相器存在着尺寸较大、结构复杂、相移量较小等问题,为克服上述缺陷,提出一种光栅-液晶复合结构太赫兹移相器,该器件结构为石英、石墨烯、液晶盒、光栅结构、石墨烯和石英组成。通过改变石墨烯电极上电压,使液晶折射率发生改变,相移器的相位因折射率改变而发生变化,通过控制外加电压可以实现对太赫兹波相移量有效调控。计算结果表明,该移相器在0.39~0.46 THz频率范围内实现了400°相移量,回波损耗小于-11 dB,在频率0.43 THz处,最大相移量达到422°。太赫兹波入射角在0°~30°范围内变化,移相器的相移量保持不变,而且该器件对入射太赫兹波偏振态不敏感。所设计的太赫兹移相器具有相移量大、结构尺寸小等优点,在未来的太赫兹通信、安检、医疗、传感、成像等领域中具有广阔的应用前景。     

Effect of sweeping the “instantaneous” lasing frequency on the amplitude-detuning characteristic of a CO2 laser with loss modulation

The influence of changes in the refractive indices of the active medium and the loss modulator on the amplitude-detuning characteristic of a CO₂ laser was theoretically investigated. It is shown that at a comparatively great magnitude of sweeping the “instantaneous” lasing frequency, the magnitude of the laser response increases not only in negative detunings, but also over a wide range of positive detunings. The use of the procedure of changing the magnitude and sign of detuning as well as the range of sweeping and the frequency of modulation makes it possible to realize various periodic and chaotic regimes of lasing, i.e., to exercise control over the time and energy parameters of pulses over a very wide range.

光谱法锌离子检测系统的研究

采取标准锌显色剂与锌发生显色反应，生成不溶于水的絮状络合物。用光谱仪测它的吸光度，研究其特征谱与吸光度的特点，建立其浓度与特征波长吸光度间的数学模型。本文所采用的显色剂主要与锌、铜、镉、镍四种离子发生络合反应。因此分别探索了四种离子高浓度以及低浓度时显色反应的吸光度，最终通过得到锌离子浓度与吸光度的关系式以及锌离子浓度与四波长下四种离子混合溶液显色后的吸光度的关系式，给出了锌离子的吸光度与总吸光度的关系式。显色反应能否满足分光光度法的要求，主要与显色剂的性质有关，同时显色反应的条件也至关重要。因为在显色反应过程中，主要是锌离子与锌显色剂发生络合反应形成络离子，进而形成絮状络合物。络离子一般比较稳定，但在水溶液中也存在着电离平衡，也就是说当显色条件发生变化时，既有可能形成络离子，也有可能发生络离子的分解，从而影响络合反应的程度。显色条件包括显色剂用量、pH值、反应温度、显色时间、待测溶液的盐度以及浊度等。重点研究待测溶液的盐度对锌离子浓度测量值的影响，并通过实验给出影响规律以及校正模型。     

Effect of spraying power on the microstructure and mechanical properties of supersonic plasma-sprayed Ni-based alloy coatings

The aim of this paper was to investigate the microstructure and mechanical properties of the supersonic plasma-sprayed Ni-Cr-B-Si-C coatings prepared at different spraying powers. The microstructure, phase composition, porosity, Young's modulus, micro-hardness, and residual stresses of the coatings were investigated and determined. The variations of the porosity, Young's modulus and micro-hardness of the coatings were evaluated by using statistical method. Results showed that the variations of porosity, Young's modulus and micro-hardness of the coatings followed the Weibull distributions. With increasing the porosity, the micro-hardness and Young's modulus of the coating decreased. The mean value of the Young's modulus of the coating calculated from Weibull plot was almost proportional to the square root of the micro-hardness of the coating. With increasing the power, Young's modulus of the coating increased, which, in turn, resulted in the increment of the residual stress at the coating surface.     

岩心光谱扫描仪数据处理应用研究

钻探是地质勘探的重要手段之一,近年来,随着我国地质事业的发展,大量岩心的存放和共享成了亟待解决的问题,研制岩心光谱扫描仪,实现岩心数字化解决了这一问题。然而,岩心光谱数据和图像数据的大量产生,对数据处理又提出了新要求。根据光谱学原理和光谱分析方法,对岩心扫描仪的光谱数据进行光谱分析和蚀变矿物填图,可以为地质科研、矿床分析和外围找矿提供依据。岩心图像也是岩心信息不可缺少的部分,由于岩心扫描仪探测器的局限性、光照条件以及岩心圆柱形的影响,会造成采集到的岩心图像光照不均和辐射畸变。使用非线性的双边滤波法来锐化图像,然后用黑白板定标的方法校正岩心图像,使岩心图像更加接近真实状况。用角点检测法进行特征点检测,完成了图像自动拼接工作,把一张张岩心图像按照岩心钻孔的顺序拼接成岩心柱和岩心盘,使岩心图像显示更直观。矿物的光谱分析是岩心扫描技术的核心,矿物不同,其特征吸收峰的位置也不同。常采用的矿物检索方法是吸收峰位匹配法,该方法适合混合矿物光谱检索。峰位匹配的依据是标准数据库,提出了分类数据库检索法,即根据矿物类型的不同,把标准数据库分为泥化蚀变矿物库、斑岩型蚀变矿物库、绢云母化蚀变矿物库等子数据库,根据样品图像及所处地质环境判断,选择合适的子数据库进行检索分析。文中进行两个实验,分别使用标准数据库和分类数据库分析同一样品,其分析结果表明准确率后者更高;使用标准数据库和分类数据库对同一批样品（141个样品）进行处理,用时分别是231和44 s。实验证明：分类数据库法不仅可以提高检索的准确度,还能大大加快检索速度,是准确、快速检索海量数据的有效方法。该方法是光谱检索中新颖、独特、有效的方法,是本文的创新之处。矿物光谱含有丰富的信息,其特征峰的峰强度、峰强比、峰位移、半高宽和反射率分别反应矿物的相对含量、相对温度、阳离子交换情况、结晶度和颜色等信息,提取同一批矿物的这些信息,对比分析,可获得成矿模型,揭示成矿规律。以安徽宣城一个钻孔为例,对岩心光谱扫描仪的数据进行自动图像拼接、光谱分析和蚀变矿物填图。从蚀变矿物信息提取图分析看出,该地区是酸性、低温的地质环境,低温区岩石颜色较深,在低温区中间也有高岭石、蒙脱石,说明具有良好的储油环境。经实践证明,该方法不仅效率高,能节省大量人工工作量,还能得到高质量的岩心盘拼接图、岩心柱状拼接和蚀变矿物信息提取图,是地质工作者处理岩心数据实用、可靠的方法。     

Analysis of the conformation composition of ethane-bisporphyrin solutions from absorption spectra in the region of the soret band

It is found that in absorption spectra of porphyrin dimers linked by a flexible bridge, the shape of the Soret band strongly depends on the solvent, which is explained by differences in the conformation composition of the dimers studied. The conformation composition was analyzed with the deconvolution method, which made it possible to resolve and sharpen all components of the complex contour, of the Soret band. Using different solvents, we studied changes in the behavior of every elementary band with a model of exciton (dipole-dipole) interaction and found that in all the solutions this dimer occurred in the form of face-to-face and side-to-side conformers. The relative content of face-to-face conformation markedly increased with the polarity of the solvent. Institute of Molecular and Atomic Physics, Academy of Sciences of Belarus, 70, F.

固态夸克星星震模型的研究

Glitch指脉冲星发生的自转角速度突然增大的现象,在许多脉冲星中都探测到了。Glitch的产生机制与脉冲星内部结构相关,而后者依然是待解决的难题。天文观测和理论研究均不能排除一类可能性,即脉冲星类天体本质上是固态夸克集团星,而固态星体发生Glitch的最自然的解释就是星震。本工作在星震模型下研究了固态脉冲星的Glitch现象。固态星体在自转减慢过程中,会发生应力能（或弹性能）的积累,当积累的应力超过星体能承受的限度,星体会发生碎裂,即发生星震,此时由于转动惯量突然减小而导致自转角速度突然增大,表现为Glitch现象。根据此模型可得到Glitch的幅度与时间间隔的关系。如果星体的质量较大而自转较慢,星震过程可能同时伴随体积的减小,即体积改变的星震,此时通常会有显著的引力能释放,可以解释观测到的反称X射线脉冲星/软伽马射线重复暴（AXPs/SGRs）;如果星体转速较快,星震过程可能只表现为形状即扁率的微小变化,此时不会有显著的能量释放。这两类Glitches可以解释观测现象。进一步的理论研究结合更多观测,有望使人们利用Glitch现象来检验固态夸克集团星这一理论猜想。The author demonstrates that how to understand the Glitches of solid pulsars in the starquake model. Glitch is the sudden spin-up during the normal spin-down process, which has been observed in many pulsars. The mechanism of Glitches is still a matter of debate because it depends on the unsolved problem that what is the nature of pulsars. One of the models of pulsars, the so-called solid quark-cluster stars, could not be ruled out by neither the astrophysics observations nor theoretical considerations. The Glitches of solid quarkcluster stars could naturally be the result of starqukes. During the spinning-down of the solid star, the strain energy develops until the stress reaches the critical value, then some parts of the star fragment, which would suddenly decrease the moment of inertia of the star, leading to the sudden increase of the rotation frequency that manifests as a Glitch. If the star has high mass or rotates slowly, the shrink of radius would happen during the starquake, leading to a huge amount of energy releasing which accounts for AXPs/SGRs. On the other hand, if the star rotates fast, only the oblateness of the star changes during the starquake, which would lead to negligible releasing of energy. This paper discusses the phenomenon of Glitches for solid quark-cluster stars, including the physical processes and consequences of starquakes, as well as the reasons for different energy releasing during Glitches. Further theoretical study combined with more observations about Glitches would be helpful for us to test the conjecture of sold quark-clusters.
