基于AHP-灰色聚类分析的高新技术成果综合转化价值评价

高新技术成果综合转化价值的测度同时受到实施企业经营绩效、项目管理团队运营能力、项目技术经济可行性分析、项目转化综合风险等四个层面因素的影响，如何整体衡量这些制约因素导致项目综合转化价值的消长，对于优选高新技术转化项目予以实施是至关重要的，本文建立基于AHP-灰色定权聚类分析方法的评价模型，收集数据开展实证分析，演示评价方法的操作流程，同时借助简要蛛网模型分解剖析高新技术成果的转化价值并提供优化策略。     

Spatiotemporally inhomogeneous plastic flow of a bulk-metallic glass

With geometrically-constrained specimens, the spatiotemporally inhomogeneous deformation of a Zr-based bulk-metallic glass in uniaxial, quasistatic, compression was investigated. Decreasing the height/width ratio of specimens from 2 to 0.5 significantly increases the plastic strain from 2% to about 80%. Using an infrared camera, we first observe in situ dynamic shear-banding operations during compression at various strain rates. The shear banding is highly dependent on strain rates, either intermittent at the lower strain rate or successive at the higher strain rate. Scanning electron microscopy observations show the spatiality of the rate-dependent shear banding. The serrated plastic flow is a result of the shear-banding operations. At the lower strain rate, more simultaneous shear-banding operations result in more obvious serrations, while at the higher strain rate, fewer simultaneous shear-banding operations cause less obvious serrations.     

高能固体激光系统设计及性能评估

近年来高能固体激光器研究及小型电源技术取得了很大的进展,使得利用电源提供能量的高能激光器在近期的应用成为可望实现的目标.但由于高能激光系统设计复杂,且造价高,需要在激光系统设计制造之前对系统性价比进行优化,并对系统性能进行评估.其中选择激光器主要考虑激光波长位于大气窗口,使得经大气传输后激光能量衰减尽可能小;光学系统设计主要考虑物理光学效应的限制及增加自适应光学系统对大气效应引起的光束畸变进行校正.大气传输与补偿模拟程序可对包括高能激光系统、激光大气传输效应等进行全程数值模拟,从而可在高能激光系统设计制造之前对系统性能进行评估,或对现有高能激光系统性能及其对靶目标的损伤效果进行评估.     

Subjective probability and causality assessment

Serious adverse reactions to a drug usually occur too rarely to be identified in the clinical trials required to demonstrate efficacy before the drug can be put on the market. Instead, they are generally first encountered in the uncontrolled world of everyday clinical practice, and the industrial and national regulatory agencies that are responsible for drug safety must rely for their first indications of a possible drug-adverse event connection on case reports submitted to them by practitioners who observe an occurrence of the event in one of their patients taking the drug. A typical situation in the work of these agencies finds a group of experts assembled around a table reviewing a small series of case reports (perhaps as small as one!) that link a particular drug with a particular type of adverse event. The experts want to determine whether, for each case in their series, the available evidence indicates that the drug caused the adverse event to occur. How are they to proceed? This paper outlines an approach to this problem, based on the use of subjective probability.     

Adaptive bivariate Chebyshev approximation

We propose an adaptive algorithm which extends Chebyshev series approximation to bivariate functions, on domains which are smooth transformations of a square. The method is tested on functions with different degrees of regularity and on domains with various geometries. We show also an application to the fast evaluation of linear and nonlinear bivariate integral transforms.

Significance of mechanoreceptors in the subglottal mucosa for subglottal pressure control in singers

According to Wyke and Kirchner (Wyke B, Kirchner J. Neurology of the larynx. In: Hinchcliffe R, Harrison D, eds. Scientific foundation of otolaryngology. London: William Heinemann Medical Books, 1976:546–66) mechanoreceptors in the subglottal mucosa play a significant role in the control of laryngeal muscle activity in response to changes of subglottal pressure during phonation. In singers this pressure is adapted not only to phonatory loudness but also to fundamental frequency. By spraying Xylocaine solution with a needle inserted into the trachea through the anterior gap between the cricoid and thyroid cartilages, the subglottal mucosa was anesthetized in three singers. The effects on subglottal pressure and fundamental frequency of this anesthesia were examined. The pressure effects varied between the subjects, whereas the fundamental frequency accuracy was adversely affected in all three subjects. The implications of these findings are discussed.     

Interacting environmental influences: Concepts of synergism,antagonism, and superposition

Since an enormous number of different pollutants is usually simultaneously present in a certain environmental area, it must be expected that interactions between these pollutants may occur frequently. Nevertheless, not very much is known about the combined impact of several pollutants and the environmental policy ignores these effects in defining pollution standards and limits just for single pollutants. Moreover, it is not at all clear how these effects should precisely be described. Starting from definitions of interactions between different environmental influences introduced by Ott [7] and one of the present authors [8], new concepts of synergism (and antagonism and superposition) in a deterministic context will be presented. It is analyzed which properties an environmental quality index has to have in order to describe such interactions.
