危险驾驶罪定罪问题探析

随着《刑法修正案（八）》的实施,理论界与司法实务界都逐渐认识到危险驾驶罪立法设置的必要性和适用的复杂性。对于犯罪的认定,需要从犯罪既遂形态类型、犯罪责任的要素、犯罪停止形态、罪数等角度进行深入分析,从而在宽严相济刑事政策精神的指导下准确认定本罪。     

基于ANSYS的悬索跨越管道地震时程响应分析

以长庆油田输油一处某悬索跨越管桥为工程背景,应用ANSYS建立分析模型,采用时程分析法进行非线性地震响应分析。按轴向、横向、竖向分别输入地震波，分析结构在三种情况下的受力特点对比，得到不同方向的抗震性能。以三、四类场地地震波为输入，考虑不同地震烈度，一致输入和行波效应下结构关键部位位移、应力值，并用时程曲线直观表达参数随时间的变化。探讨了悬跨管桥在不同地震动情况下的受力特点和规律，找出薄弱环节并提出了改进措施，为地震预防及灾后拯救提供了一种有效途径。     

Uncertain Benefits Estimates for Reductions in Fine Particle Concentrations

The Environmental Protection Agency's (EPA's) estimates of the benefits of improved air quality, especially from reduced mortality associated with reductions in fine particle concentrations, constitute the largest category of benefits from all federal regulation over the last decade. EPA develops such estimates, however, using an approach little changed since a 2002 report by the National Research Council (NRC), which was critical of EPA's methods and recommended a more comprehensive uncertainty analysis incorporating probability distributions for major sources of uncertainty. Consistent with the NRC's 2002 recommendations, we explore alternative assumptions and probability distributions for the major variables used to calculate the value of mortality benefits. For metropolitan Philadelphia, we show that uncertainty in air quality improvements and in baseline mortality have only modest effects on the distribution of estimated benefits. We analyze the effects of alternative assumptions regarding the value of reducing mortality risk, whether the toxicity is above or below the average for fine particles, and whether there is a threshold in the concentration‐response relationship, and show these assumptions all have large effects on the distribution of benefits.     

Statistical techniques in stereology

Stereology typically concerns estimation of properties of a geometric structure from plane section information. This paperprovides a brief review of some statistical aspects of this rapidly developing field, with some reference to applications in the earth sciences. After an introductory discussion of the scope of stereology, section 2 briefly mentions results applicable when no assumptions can be made about the stochastic nature of the sampled matrix, statistical considerations then arising solelyfrom the ‘randomness’ of the plane section. The next two sections postulate embedded particles of specific shapes, the particular case of spheres being discussed in some detail.

References are made to results for ‘thin slices’ and other prob-ing mechanisms. Randomly located convex particles, of otherwise arbitrary shape, are discussed in section 5 and the review concludes with a specific application of stereological ideas to some data on neolithic mining.     

腈纶皂化制备电流变液悬浮粒子的研究(英文)

为了制备无水电流变液用悬浮粒子，研究了腈纶在碱性条件下的多相水解。详细考察了皂化试剂氢氧化钾的用量，皂化时间和温度等皂化条件对皂化程度的影响; 讨论了氰基转化过程。研究结果表明，在皂化初期，腈纶分子链上的氰基转化为酰胺基，然后缓慢转化为羧基。给出了一条制备无水电流变液用悬浮粒子的方法，并初步考察了该类电流变液的控光特性。

《扬子法言》中句末连用语气词汇释

语气词是用来帮助表示各种语气的。当几个语气词连用时,语气的表达上往往存在主次之分,语气的重心一般落在最后一个语气词上,其作用是加强之前语气的表达效果。《扬子法言》一书中句尾语气词连用的现象非常多。其中以两个语气词连用为多见,有"已乎""也哉"、"矣夫"、"也与"、"也者"、"矣乎"、"矣哉"、"也夫"、"乎哉"、"而已"等;也有三个语气词连用的情况,如"也已矣"、"而已矣"、"已矣哉"、"几矣哉"。不同语气词的选择使用可以让作者的思想感情更完整的展现在读者面前。

纳米氧化铁材料的磁弛豫研究

由Fe-O的超细粉末压制成纳米固体，该过程使相邻微粒间形成界面。由于总体的磁弛豫依赖于有效各向导性能，界面的存在出现的界面各向异性能将会改变纳米的磁弛豫行为．对α-Fe2O3和γ-Fe2O3的Mossbauer谱研究测量表明在抑制起顺磁弛豫时，界面的交换相互作用是主要的。
