风险刑法中的抽象危险犯之检讨

在风险社会下,法益概念出现了具体向抽象、个人向超个人、人本向非人本的时代嬗变;抽象危险犯在风险刑法中正日益增多,但也遭受着传统刑法的种种质疑;抽象危险犯是对风险社会特质的有效回应,其功能吻合于风险社会中对犯罪的认定,而且其弊端是可以采取恰当的刑法解释方法避免的。     

Detoxification of Chemical Warfare Agents Using a Zr6‐Based Metal–Organic Framework/Polymer Mixture

Owing to their high surface area, periodic distribution of metal sites, and water stability, zirconium‐based metal–organic frameworks (Zr₆‐MOFs) have shown promising activity for the hydrolysis of nerve agents GD and VX, as well as the simulant, dimethyl 4‐nitrophenylphosphate (DMNP), in buffered solutions. A hurdle to using MOFs for this application is the current need for a buffer solution. Here the destruction of the simulant DMNP, as well as the chemical warfare agents (GD and VX) through hydrolysis using a MOF catalyst mixed with a non‐volatile, water‐insoluble, heterogeneous buffer is reported. The hydrolysis of the simulant and nerve agents in the presence of the heterogeneous buffer was fast and effective.     

Study on hydrogen sulfide plasma passivation of 790-nm laser diode cavity surface

In order to improve the optical properties of the Ⅲ-Ⅴ laser diodes(LDs) by means of H2S plasma passivation technology,H2S plasma passivation treatment is performed on the GaAs(110) surface.The optimum passivation conditions obtained are 60-W radio frequency(RF)power and 20-min duration.So the laser cavity surfaces axe treated under the optimum passivation conditions.Consequently,compared with unpassivated lasers with only AR/HR-coatings,the catastrophic optical damage (COD) threshold value of the passivated lasers by H2S plasma treatment is increased by 33%,which is almost the same as that of (NH4)2Sx treatment.And the life-test experiment has demonstrated that this passivation method is more stable than(NH4)2Sx solution wet-passivated treatment.     

混凝土内时损伤本构模型

应用内时理论和损伤力学建立了混凝土内时损伤本构模型。该模型的特点是：混凝土的弹塑性特性由内时理论描述，而微裂缝由损伤力学来描述。前者使本构模型摆脱了一般弹塑性模型中的屈服面的概念，从而简化了非线性计算过程；后者使微裂缝引起的软化、休积膨胀等效应都可由损伤变量来考虑，从而既反映了混凝土的本质特性，又使模型的参数和基本方程大大减少。应用本文建议的本构模型于各种实例分析中，所得计算结果与试验结果符合较好。
