宽严相济刑事政策下恢复性司法的应用

宽严相济是我国现阶段的刑事政策,恢复性司法的恢复性正义理念与此相契合;恢复性司法具有弥补受害人所受伤害、矫正犯罪行为、平复被破坏的社会关系等功能;在其本土化构造的过程中,必须结合我国国情对其进行规制和完善,以达到法律效果与社会效果的统一,从而促进社会和谐。     

Experimental Study on the Expansion Uniformity of Armature

A measurement system has been developed based on high-precision printed probes in printed circuit board (PCB) and steep rising-time probe adapters,which can be applied to study the expansion uniformity of armature in a helical magnetic flux compression generator (HFCG).The influences of wall thickness and initiation position on the expansion uniformity of armature in HFCG were experimentally investigated.The results show that the armature with thinner wall thickness will easily rupture due to the high pressure of detonation products inside,the armature with larger wall thickness will easily crack due to the tensile stress on the outer surface of the wall,the influence of the end effect on the expansion uniformity can be ignored if the distance between the first group of probe and the initiation point is more than 3 times the armature diameter.     

基于RTD曲线连铸中间包优化设计数值模拟

为了优化连铸中间包内型,采用数值模拟方法计算钢液在连铸中间包内的停留时间分布（RTD）,并通过RTD曲线分析了连铸中间包内挡坝高度和位置对其钢液流场的影响。结果表明,结构优化后的连铸中间包钢液流场趋于合理,死区体积分数由原始方案的17.62%降至13.29%,且钢液在连铸中间包内的停留时间变化不大。     

皮胶原纤维固载Zr(IV)对水体中苯羧酸的吸附特性

制备皮胶原纤维固载Zr(IV)吸附剂(ZLCF),并考察ZLCF对水体中苯甲酸(BA)、邻苯二甲酸(o-PA)、对苯二甲酸(p-PA)和间苯二甲酸(m-PA)的吸附特性.研究表明:这4种苯羧酸的吸附平衡同时符合Langmuir和Freundlich方程,但随着它们的羧基数量和位置的不同,其吸附容量也随之变化.总体看,ZLCF对所研究的苯羧酸均具有较大的吸附容量.当苯羧酸溶液(10 m1)的初始浓度为6 mmol/L、吸附温度为293 K时,ZLCF(0.05 g)对BA、o-PA、m-PA和p-PA的吸附容量分别达0.4616、0.5892、0.4912和0.3138 mmol/g.吸附动力学研究表明:BA的吸附符合拟一级速率方程,边界层扩散为主控步骤;而o一PA、m-PA和p-PA的吸附符合拟二级速率方程,化学吸附为主控步骤.

芯子开槽工艺对蜂窝纸板缓冲性能的影响

为解决蜂窝纸板初始缓冲性能差、干燥速度慢、易发霉等问题,对蜂窝纸芯采用开槽工艺处理,在不显著降低蜂窝纸板平压强度的前提下,尽可能地改善其缓冲性能。采用正交试验方法对30 mm厚蜂窝纸板进行静态压缩试验,以考察芯子槽形的宽度、深度和槽间距3个工艺参数对蜂窝纸板性能的影响。实验结果表明:当采用槽宽2.5 mm、槽深3 mm、槽间距32 mm的开槽方式时,蜂窝纸板具有较优的抗压与缓冲综合性能。     

Material removal mechanism and crack propagation in single scratch and double scratch tests of single-crystal silicon carbide by abrasives on wire saw

Single-crystal silicon carbide is a promising semiconductor material widely applied in micro-electronics. However, its high hardness and brittleness make it difficult to be sliced into wafers by wire sawing technology. In this paper, both single scratch and double scratch tests are carried out on the (0001) surface of 4H-SiC by the abrasives on wire saw instead of using a standard indenter to obtain an in-depth understanding of the material removal mechanism and crack propagation in wire sawing. The scratching groove in single scratch tests is found to be composed of several small grooves because of the actual irregular shape of the abrasive. Stress analysis shows that this phenomenon has relatively small effects on the radial cracks propagating near the $\{1\overline{1}00\}$ primary cleavage plane. Radial cracks play an important role in the process of material removal by means of the interaction between radial cracks and the interaction between radial cracks and lateral cracks in double scratch tests. Based on fracture mechanics, the variation of stress intensity factors (SIFs) at the tip of radial cracks with the separation distance between the two grooves is calculated. Results show that the values of SIFs increase with the decrease of the separation distance, which means that radial cracks are more easily to propagate when the separation distance decreases. The theoretical analysis agrees with the experimental observation.     

Theoretical investigation on cyclic reciprocal derivative chronopotentiometry: Kinetic study of totally irreversible electrode processes

Theoretical expressions and mathematical analysis in cyclic reciprocal derivative chronopotentiometry (CRDCP) are presented for totally irreversible electrode processes corresponding to the application of symmetrical and unsymmetrical programmed currents. For two successive unsymmetrical programmed currents, the effect of the currents ratio b (b = |I₂(t)/I₁(t)|) on the (dt/dE)–E curves is discussed. The electrochemical behavior of totally irreversible electrode processes has been studied corresponding to the application of the unique unsymmetrical programmed Φ^m(I₀) proposed recently. CRDCP characteristic parameters obtained for totally irreversible electrode processes are different from those of reversible electrode processes. Therefore, a comparison of CRDCP between both mechanisms is presented. Based on the mathematical derivation, alternative methods for kinetic measuring are described. It is prospected that CRDCP is convenient and applicable for studying the reversibility of the electrode processes in form of CRDCP characteristic parameters.     

PBH/PP及PBH/CaCO_3/PP共混改性研究

采用自制的负载钛催化剂[TiCl4/MgCl2-Al(i-Bu)3],合成了1-丁烯-1-己烯共聚物(PBH)。用己烯摩尔含量为2%、7%、20%的PBH对PP进行共混,研究了共混物的力学性能;以己烯初始摩尔含量为30%的PBH作为CaCO3的载体,填充PP,并与未采用载体的CaCO3填充体系进行比较。结果表明:随着PBH含量的增加,在共混物拉伸强度、弯曲强度、硬度有一定下降的同时,冲击强度则明显提高,己烯摩尔含量大的PBH增韧改性PP的效果更好;以PBH作为载体的CaCO3,随着其含量的增加,共混物的冲击强度明显增大,而拉伸强度、弯曲强度、硬度却有一定程度的下降。与无PBH载体CaCO3填充PP的规律明显不同。
