研究背景：牙种植体即刻负载是指在种植体植入后立即进行上部结构修复的种植治疗方法，此法不但可尽快为患者恢复美观、咬合功能等，而且可减少手术次数、缩短治疗时间，受到患者和医生的欢迎。

The RFPA (realistic failure process analysis) software is used to analyze the deformation/failure of a tunnel passing through the rock mass with incompetent laminar structural planes at different obliquities and the displacement of the key points around the tunnel, with microdimensional elements introduced in combination with the elementary constitution model based on damage mechanics and statistics.

通过引入细观层次的微元体，采用损伤力学和统计理论的单元本构模型，利用岩石破裂过程分析软件RFPA(realistic failure process analysis)，对具有不同倾角层状软弱结构面岩体中隧道的变形破坏特征、隧道周边关键部位的位移进行了分析。

The thiopeptides, by binding within a cleft located between the ribosomal protein L11 and helices 43 and 44 of the 23S rRNA, overlap with the position of domain V of EF-G, thus explaining how this class of drugs perturbs translation factor binding to the ribosome.

核糖体蛋白L11和23SrRNA的43/44螺旋结构形成裂隙，L11的构象变化能够加宽该裂隙从而允许延伸因子EF-G插入，促使GTP水解，为肽链延伸合成过程中核糖体的构象变化提供能量，而Thio能够与L11和23sRNA结合，阻止L11的构象变化，使该裂隙处于闭合状态，抑制EF－G在延伸过程中的作用。

By transforming the three direction DEXEL model of polyhedrons into its VOXEL model and setting transparency attributes of VOXELs,the porous structure of artificial bone can be designed.

通过将多面体三向DEXEL模型转换为小体素模型，并设置小体素的透明度属性为全透明，实现人造微孔骨结构设计。

Commonly in the biomass briquetting machine, hydraulic cylinder directly impulses the covering for lock and unlock in the covering mechanism for closing and unclosing. But the unlock angle was finite in this kind of scheme.
