Some compounds possessing chiral center themselves may be racemates and appear racemic phenomenon in the extraction and separation from medicine herbs, structure modification and chemical synthesis.

但是，由于含有手性中心的中药有效成分本身可能是消旋体、或者在分离提取、结构改造及化学合成时会出现外消旋化现象，使新药研制与开发中面临对映体成分的分离制备、体内手性药物分析及对映体特异性药代动力学研究等重大难题。

In this paper, the authors found the pyritized rod-like bacteria in desmocollinite and the Cyanophytes's gelationous sheath and the degraded organic matter of blue green algae in collinite of high-sulfur coal seams No.9 w(So=2.67% and No.10 w(So=2.54% using SEM-EDX and TEM. These findings of bacteria and algae suggest that they play an important role in the high-sulfur formation.

应用带能谱仪的扫描电镜和透射电镜，在乌达矿区高硫煤9煤层和10煤层的基质镜质体中发现了黄铁矿化的杆状菌落，在无结构镜质体中发现了蓝藻胶鞘及其降解有机质，这些菌藻类体的发现表明低等生源在高硫煤形成过程中起了重要作用。

The fluid end of the plunger pump was analyzed with three-dimensional finite element method,and the distribution law of stress at the fluid end was obtained.

对某柱塞泵泵头体进行了三维有限元分析，获得了泵头体的应力分布规律，并应用ANSYS软件对泵头体的结构进行了优化，为类似的壳体零件的优化设计提供了依据。

This paper examines the cracks appeared in the retaining wall beside the FeiYuze tunnel uplink secondary lining vault. The seismic CT technology was used to investigate the engineering geology structure of the covering rock mass above the tunnel. The results indicate that the rock mass had three fracture zones along tunnel axial and the rock mass quality in the small mileage entrance section was poor.

针对飞鱼泽隧道的上行线二衬拱顶靠档墙处出现裂缝，经地震CT技术查清隧道上所覆盖岩体的工程地质结构结果表明，沿隧道轴向存在三个岩体破碎带，其中在小里程入口段，岩体完整性较差。

Torsion would be produced when curve beam under self-weight load, and, torsion and radial force would be produced when structure under prestress load. Such forces would brought prominent side reactions.

在施工阶段和运营阶段，就曾发生过梁体侧向倾覆、支座脱空，墩柱开裂、梁体体侧移以及腹板侧向崩裂等曲线梁结构侧向效应病害，这是技术人员对曲线桥特性把握不够造成的。

Furthermore, the effects of ligands, metal and reaction time on the reaction were also researched, and the process of new ligand-metal catalysis for Diels-Alder reaction was also analyzed according to Evans" square planar mode and Corey"s tetrahedral manner.
