宇宙主胁量限定粒子质量、微观临界尺寸和真空光速（胁量力学初导IV）

扩展到任意质量体的宇宙主胁量描述。宇宙主胁量同质量之间只差一个常量系数。宇宙主胁量创造了粒子的质量，造就了粒子的微观临界尺寸，构筑了恒定而有限的真空光速。     

多孔硅红外光激发上转换兰光特性

采用电化学腐蚀法制备多孔硅（ＰＳ），测量了ＰＳ在近红外光（８００ｎｍ）激发下的光致发光（ＰＬ）谱和光致发光激发（ＰＬＥ）谱，结果表明ＰＳ具有良好的上转换荧光特性，并随着存放时间的延长，在一定期了内峰值强度有明显的增强，这种非线性光这响应的增强，被认为与空间量子限制效应作用下局域束缚激子被激发有关，硅片初始电阻率赵低发光强度越大。

A study of Reduced-Rank stap

This paper starts with the discussion of the principle of Reduced-Rank (RR) Space-Time Adaptive Processing (STAP). It is followed by a dedication of the upper bound performance of all eigen-based RR methods provided by Cross Spectral Method (CSM) under the condition of a given processor rank and an identical secondary sample size. A performance comparison between two RR STAP processors with prefixed structure and CSM is performed by the means of simulations. It is shown that the performance of time pre-filtering followed by jointly localized STAP structure (i.e. 3DT-SAP) is very close to the upper bound and thereby it is an effective RR approach.

A case study in the mechanical verification of fault tolerance

To date, there is little evidence that modular reasoning about fault-tolerant systems can simplify the verification process in practice. This question is studied using a prominent example from the fault tolerance literature: the problem of reliable broadcast in point-to-point networks subject to crash failures of processes. The experiences from this case study show how modular specification techniques and rigorous proof re-use can indeed help in such undertakings.     

Modelling of light extinction by soot particles

A simplified model for the prediction of light extinction through combustion generated smoke is presented. The model builds upon existing theory and available experimental data to account for the principal factors that influence light extinction in participating media, including wavelength, primary particle size distribution and morphological structure of particle aggregation as well as multiple scattering among particles within a particle aggregation. Good agreement is demonstrated between the model predictions and experimental data in the visible and IR ranges. The model illustrates that as the mean particle size increases, the integral optical property of a soot cloud approaches that of monodisperse particles. It is postulated in the current study that the number of particles participating in multiple scattering is around 20 regardless of the real size of particle aggregation.
