听障儿童个性及与人际信任关系的研究

以艾森克人格问卷（EPQ）、人际信任量表（ITS）为工具，对山东省特殊教育中等专业学校的185名听觉障碍儿童的个性特征、同伴信任及他们之间的关系进行了测量研究，目的是改善听觉障碍儿童的人格状况，为特殊教育工作提供干预依据。结果表明：男听障儿童倔强性更显著；城镇听障儿童或家长懂手语的听障儿童更倾向于外向；听障儿童个性的精神质因子与同伴信任的可依靠性存在显著的负相关，情绪稳定性与信赖性存在显著的负相关，掩饰性与信赖性存在极其显著的正相关。

泛家族主义文化对城市农民工的影响

泛家族主义文化的影响已深入到我国社会的各个角落，它对城市农民工进城之初有着积极的作用，但并不利于农民工的长期发展。农民工是我国城市现代化建设的一支生力军，因此有必要采取有效措施引导泛家族主义文化良性发展并最终以先进的现代化文化取而代之，最终实现整个社会的城市化、工业化的现代化发展目标。

Identification and quantification of the antipsychotics risperidone,aripiprazole, pipamperone and their major metabolites in plasma using ultra‐high performance liquid chromatography–mass spectrometry

The antipsychotics risperidone, aripiprazole and pipamperone are frequently prescribed for the treatment in children with autism. The aim of this study was to validate an ultra‐high performance liquid chromatography–mass spectrometry method for the quantification of these antipsychotics in plasma. An ultra‐high performance liquid chromatography–mass spectrometry assay was developed for the determination of the drugs and metabolites. Gradient elution was performed on a reversed‐phase column with a mobile phase consisting of ammonium acetate, formic acid in methanol or in Milli‐Q ultrapure water at a flow rate of 0.5 mL/min. The method was validated according to the US Food and Drug Administration guidelines. The analytes were found to be stable enough after reconstitution and injection of only 5 μL improved the accuracy and precision in combination with the internal standard. Calibration curves of all five analytes were linear. All analytes were stable for at least 72 h in the autosampler and the high quality control of 9‐OH‐risperidone was stable for 48 h. The method allows quantification of all analytes. The advantage of this method is the combination of a minimal injection volume, a short run‐time, an easy sample preparation method and the ability to quantify all analytes in one run.

Influence of floating-ring-electrode on large-aperture liquid crystal lens

Large-aperture liquid crystal (LALC) lens with hole-patterned electrodes possesses small lens power and high addressing voltage because of the thick dielectric layer inserted between the hole-patterned electrode and LC layer. With an embedded narrow floating ring electrode (FRE), the lens power and addressing voltage of the LALC lens could be effectively increased and decreased, respectively. In this study, we analyse the electro-optic performance of LALC lens upon variation of the diameter of the embedded FRE. Results reveal that the FRE diameter determines the electric-field distribution and hence the electro-optic behaviour of the LALC lens. The LALC lens with embedded 2-mm-diameter FRE has excellent lens properties, such as low aberration, high focal quality and modulation transfer function performance comparable with solid glass lens.     

Characteristic behaviour of plasma fluctuations inside a plasma bubble in presence of a magnetic field due to the formation of a potential well

Experiments were carried out to observe the effect of a magnetic field and grid biasing voltage in presence of a plasma bubble in a magnetized, filamentary discharge plasma system. A spherical mesh grid of 80% optical transparency was negatively biased and introduced into the plasma for creating a plasma bubble. Diagnostics via an electrical Langmuir probe and a hot emissive probe were extensively used for scanning the plasma bubble. Plasma floating potential fluctuations were measured at three different positions of the plasma bubble. The instability in the pattern showed the dynamic transition from periodic to chaotic for increasing magnetic fields. Time scale analysis using continuous wavelet transform was carried out to identify the presence of non‐linearity from the contour plots. The mechanisms of the low‐frequency instabilities along with the transition to chaos could be qualitatively explained. Non‐linear techniques such as fast Fourier transform, phase space plot, and recurrence plot were used to explore the dynamics of the system appearing during plasma fluctuations. In order to demonstrate the observed chaotic phenomena in this study, characteristics of chaos such as the Lyapunov exponent were obtained from experimental time series data. The experimentally observed potential structure is confirmed with numerical analysis based on fluid hydrodynamics.     

U型或浮头式换热器管板中的热应力及其主要影响因素研究

采用有限元法研究了U型或浮头式换热器管板中的热应力，并考察了管板厚度及管壳程对流换热系数的影响。研究结果表明，对于U型或浮头式换热器，管板内仍存在较大的热应力，这是由于管板上换热管中热量传递造成的，并且当管板较厚时这种应力更为突出；在管程走热流体时，管板两侧表面存在拉伸热应力，降低管板厚度可以有效地降低由热载荷引起的管板壳程侧表面热应力，壳程侧表面热应力可由40 MPa降至-13 MPa；壳程传热系数对管板温度场的影响明显，在换热器设计中使对流换热系数较低的介质走壳程有利于降低管板的热应力。
