Each unitis of different biotic characters and displays different features of seawater composition during the time. 2 The black unit including a biotic extinction was caused by oceanic anoxic event. Crisis that deepwater keeled foraminifera encountered represents a ferocious anoxia in deep marine environment . Biotic recovery in gray unit reflects gradually improved marine circumstance. What the biotic extinction at the C/T boundary in black unit reflects an environmental mutation, whereas the gradual biotic change characterize the recovery of marine dissolved oxygen environment in a stepwise process. The red unit is the result of oxic deposition and characterized by extremely abundance of foraminiferal faunas, which reflects a high-oxidized marine circumstance. 3 As the most ordinary biotic index in paleoceanography researches, foraminifera represent anexcellent environmental indicator in this paper.

三套岩层表现出不同的生物特征，并指示出当时海水的不同性质。2黑层段是大洋缺氧造成的结果，生物大量灭绝，深层水具旋脊有孔虫的所遭受的危机反映出当时海洋深层水体严重缺氧的特征；灰层段中生物的恢复反映出海洋环境自缺氧事件之后的逐步改善过程，与黑层段反映的C/T 界线处生物绝灭反映的环境突变不同，灰层段生物特征的渐变指示出当时海洋溶解氧环境的恢复也是一个逐步的过程；红层段属于富氧沉积的产物，特征是有孔虫生物的极度繁盛，反映的是一种高氧化性的海洋环境。3有孔虫作为古海洋研究中最常用的生物指标，在本文研究中显示了良好的环境指示性。

To facilitate the applications of biologically functional protein in drug design, it is necessary to have a thorough understanding of their conformations and their interactions with the receptors. NMR spectroscopy has the unique ability to retrieve information about 3D structures of proteins and their interactions with the target proteins in solution. Many NMR techniques have been used to study a number of pharmaceutically important proteins and characterize their interactions with the targets. In this review, we will introduce these NMR methods and show how to utilize them for protein drug design.

为了设计具有生物功能性的蛋白质来当作药物，我们必须对其蛋白质结构与其受体在结合时的作用有完整清楚的了解，而核磁共振光谱具有独特的能力，可以获得溶液状态下蛋白质结构以及蛋白质与标的蛋白质交互作用间的资讯，目前已有许多核磁共振光谱技术运用到蛋白质药物的研究，并确认它们与其标的蛋白质间的作用模式，笔者将在本文中介绍这些技术，以及如何运用它们来获取重要资讯，俾设计蛋白质药物。

Weibull distribution function is used to characterize phenomenologically the debonded probability of the interface, which is decided by the tensile stress of the particle. A partially debonded isotropic spherical elastic particle is replaced by an equivalent, perfectly bonded spherical particle, which possesses yet unknown transversely isotropic elastic moduli. The fictitious particles can be determined in such a way that their tensile and shear stresses will only vanish in the debonded direction.

认为颗粒增强金属基复合材料的界面脱黏受控于颗粒所受的拉应力，引入Weibull分布函数描述颗粒脱黏概率，且受单向拉伸载荷作用时，仅在沿受力方向的上下两侧发生部分界面脱黏，从而将部分脱黏的各向同性颗粒由一完好的横观各向同性颗粒来等效，建立了部分脱黏模型。
