Combined the geological analysis with analogue modeling experiments,the evolution of the Yinggehai basin could be divided into four main stages:(1) Before 42Ma,controlled by the southeastward extension of the Beibu Gulf basin on the northern continental margin,the Yinggehai basin experienced dextral pull-apart.Bounded by NS-trending Yingxi fault,the transtensional areas mainly are the northwest part and along the eastern boundary of the basin.(2) From 42 to 21Ma,the development of the main rift body in Yinggehai basin was mainly controlled by the southward slip and clockwise rotation of the Indochina block along the Red River fault zone,and the sedimentation was strengthened due to the sinistral transtension.In the east,the subsidence is deepened due to the dextral transtension.(3) From 21 to 10.4Ma,the sinistral movement of the Indochina block slowed down to still.From 21 to 15.5Ma,the northwest part of the basin began to inverse locally because of post-rift thermal subsidence of the whole basin.(4) From 10.4Ma to present,the basin was affected by the dextral movement of the South China block along the Red River fault zone and thermal accident in a new phase at 5Ma.
结合地质分析和物理模拟实验,莺歌海盆地的演化大致可以分为以下4个主要阶段:早期(42 Ma以前)主要受到南海北部陆缘裂解造成的右旋转换伸展作用的影响,但影响范围较小,主要为莺歌海盆地西北部和东部边界。42~21 Ma期间,主要受控于印支地块左行走滑和顺时针旋转作用的影响,莺歌海盆地在此期间发育了主体裂陷体系,东侧受到右旋转换伸展应力场的叠加影响而导致沉降加强;21~10.4 Ma期间,受印支地块逐渐减弱直至停止的左行走滑作用的影响,盆地西北部在21~15.5 Ma期间发生局部反转褶皱,但盆地整体进入以热沉降为主的时期;10.4 Ma以后,盆地受华南地块沿红河断裂右旋走滑作用和5 Ma以后新一期热事件的影响。

Based on these, an improving μ-synthesis is presented, with which the high-purity distillation is designed well. 2. The robust performance problem of MIMO plant is explained with the plant direction angle, which shows that the robust performance varies with different input uncertainties and the μ-synthesis should be applied correctly according to the uncertainty structure. 3. Condition number and bandwidth are the important items for robust performance design in MIMO system. The H〓 two-block problems can not deal with the robust performance design of MIMO system because of the condition number cancellation. A general μ-synthesis procedure for MIMO system with uncertainties is presented. 4. For the SISO system, the object function in robust performance is amplified by at most 〓 than that of H〓 two-block problems in value: So the robust performance of SISO system can be done with the H〓 two-block problems to avoid the complicated μ-synthesis procedure. 5. All the conclusions and methods presented in this paper are demonstrated by some typical design examples.
从而形成一种改进的μ综合方去,并对精馏塔病态对象进行了鲁棒性能设计,得到令人满意的结果;(2)利用对象的方向角解释了MIMO对象鲁棒性能设计出现问题的原因,并提出不同输入摄动形式下系统的鲁棒性能问题也并不相同,因此利用μ综合处理鲁棒性能设计时,应根据不同的摄动情况采用不同的结构进行设计:(3)条件数问题和带宽问题是MIMO系统鲁棒性能设计的两个主要问题,指出由于条件数对消的存在使得一般H〓两块问题无法处理MIMO系统的鲁棒性能设计,而μ综合方法则是处理MIMO系统鲁棒性能设计的有效方法,并给出了其处理MIMO系统鲁棒性能设计的一般性方法;(4)提出对于SISO系统H〓两块问题(S/T问题、S/KS问题)的设计指标函数与鲁棒性能设计的μ指标函数在数值上最大差〓倍,因此对于一般SISO系统的鲁棒性能设计可以简单地用一般的H〓的两块问题处理,而避免μ综合设计的复杂过程;(5)本文中提出的结论和算法都利用H〓/μ发展中的典型例子:Doyle-Stein问题,Safonov的战斗机模型,精馏塔对象等进行了设计验证。
