In view of practical problem during Sulige gas field development, this paper complete follow study content. Study material balance theory of two district compound gas reservoir. Carry out stress sensitivity experiment on matrix rock and labor created fracture core from Sulige gas field with America Core Company high pressure high temperature flow experimental instrument to study stress sensitivity change rule of different permeability matrix rock and created fracture core at the condition of time and again switch on and off well and different drawdown pressure. Carry out depletion experiment on matrix rock of different permeability serial combination with different kinds of allocation, using double core clamper serial connected experimental apparatus, to study gas well production performance of bi-zonal compound low permeability reservoir during low pressure production stage. At the basis of experimental study, establish single well simulation model to analyze development index infection caused by stress sensibility and production performance infection rule caused by inner formation and outer formation of bi-zonal compound gas reservoir permeability variation while considering stress sensitivity.

针对苏里格低渗气田开发中存在的实际问题，完成以下研究内容；研究了两区复合气藏物质平衡原理；利用美国岩芯公司高温高压流动实验仪，对取自苏里格气田基质岩芯和人工造缝岩芯进行应力敏感实验，研究不同渗透率基质岩芯和造缝岩芯在多次开关井和不同生产压差条件下的应力敏感变化规律；采用双岩芯夹持器串联实验装置，对不同渗透率串联组合的基质岩芯进行各种配产条件下的衰竭实验，研究两区复合的低渗储层气井在低压生产阶段的生产动态特征；在实验研究的基础上，建立单井模拟模型分析储层应力敏感性和非均质性对开发指标的影响，研究考虑应力敏感时两区复合气藏储层中内区和外区渗透率变化对开发动态的影响规律。

FTY720 dose-dependently reduced atherosclerotic lesion formation, both in the aortic root and brachiocephalic artery, and almost completely blunted necrotic core formation.

FTY720的剂量依耐性可同时减少主动脉根部和头臂干动脉粥样硬化病变的形成，并且几乎能全部减弱坏死中心的形成。

The dynamic behaviou r of chromatid core formation suggests that this structure represents a real str cutural component existing in metaphase chromosomes and that it may play certain important role in the maintenance,stabilization and condensation of chromos omes.

染色体形成的动态行为，一方面暗示了这种结构在染色体集缩和维持中期染色体的形态方面起某种重要作用；另一方面说明了轴是染色体中存在的一种真实结构。
