犯罪分层理论的展开:梳理、价值与架构

犯罪分层是指根据犯罪的严重程度将所有犯罪划分为不同层次的犯罪分类方法。犯罪分层理论既有刑事法上的意义,又有刑事政策上的意义;既有刑事实体法的积极意义,又有刑事程序法与刑事执行法上的积极功能。世界大多数国家刑法典采用犯罪分层的做法,但是,犯罪分层无论是我国刑事立法还是刑事法理论研究,尚处于未知领域。为此,我们欲通过对世界各国犯罪分层实践的现实考量,分析我国犯罪分层理论展开的必要性,在此基础上,探索性提出我国犯罪分层理论框架。     

An examination of the Clegg impact hammer test with regard to the playing performance of synthetic sports surfaces

One of the tests used to evaluate the performance of sports surfaces measures the peak deceleration of a rigid mass during contact with the surface, after being dropped from a set height. It is widely used and is included in a number of international standards. The test was carried out using two drop heights on four different designs of artificial cricket pitch, with a full set of acceleration data being collected over the duration of impact. These data were then integrated twice with respect to time to produce velocity and displacement information. Oblique impacts of cricket balls were also carried out and analysed using a high-speed video system to evaluate the playing performance of each pitch design. It was found that, although the pitches gave quite different readings of peak deceleration, they produced similar values for coefficient of restitution and were therefore considered to ‘play’ in a very similar way. This was due to a high peak deceleration reading being accompanied by a short contact time and low peak deceleration being accompanied by a long contact time, meaning that the change in momentum was similar in both cases. It was concluded that for accelerometer tests to be useful, all the acceleration-time data should be analysed, rather than the peak value alone.

Au与ZnO极性表面相互作用的第一原理计算

采用第一原理研究了Au在ZnO两个极性表面（0001）-Zn和（0001）-O的吸附,分析了单层Au吸附在ZnO极性表面上的态密度和吸附构型.计算结果表明：ZnO极性表面上单层Au吸附层能提高Zn原子在（0001）-Zn和（0001）-O面上的吸附能分别0.41 eV/原子和0.42 eV/原子;同时Au吸附层又比Zn吸附层更加活跃,总能计算可以看出Au处于顶端的构型比Au扩散构型更加稳定,使得Au恒处于顶端,很好的解释了Au在ZnO纳米结构生长过程中充当表面活性剂的角色.理论计算与实验中发现Au颗粒总是在生长出的纳米结构的末端这一现象吻合很好.

Similarity-based denoising of point-sampled surface

A non-local denoising (NLD) algorithm for point-sampled surfaces (PSSs) is presented based on similarities, including geometry intensity and features of sample points. By using the trilateral filtering operator, the differential signal of each sample point is determined and called "geometry intensity". Based on covariance analysis, a regular grid of geometry intensity of a sample point is constructed, and the geometry-intensity similarity of two points is measured according to their grids. Based on mean shift clustering, the PSSs are clustered in terms of the local geometry-features similarity. The smoothed geometry intensity, i.e., offset distance, of the sample point is estimated according to the two similarities. Using the resulting intensity, the noise component from PSSs is finally removed by adjusting the position of each sample point along its own normal direction. Experimental results demonstrate that the algorithm is robust and can produce a more accurate denoising result while having better feature preservation.

应用于承载骨的梯度多孔支架力学性能研究

基于三周期极小曲面(TPMS)设计5种不同孔隙率梯度分布的梯度多孔支架,利用选区激光熔化(SLM)技术制造Ti6Al4V梯度多孔支架。该支架具有类似于人骨梯度多孔结构的梯度孔隙率。压缩测试结果表明,5种梯度多孔支架的弹性模量为8.75~13.88 GPa,抗压强度为219.48~ 528.21 MPa,符合承载骨的弹性模量和抗压强度要求。弹性模量和抗压强度都随着平均孔隙率P- (或边缘孔隙率PB )的增大而减小,P-对弹性模量和抗压强度的影响大于PB。采用Gibson-Ashby的拟合结果可以为承载骨的设计提供参考。
