ABSTRACT The main content of this dissertation is focused on formal Verification of Hybrid Systems with complex continuous dynamics. The research pivot is to solve the difficulties of Discrete model Approximation of Complex Continuous dynamics .

本文所有论述均围绕着解决具有复杂连续动态混合系统的形式验证这个主题而展开，以解决验证中复杂连续动态的离散近似所存在的困难为研究重点。

On the basis of Muskhelishvili's complex function theory, an auxiliary field of mixedmode crack was accomplished, and then using Betti's reciprocal work theorem, a path independent contour integral method for stress intensity factors of mixed-mode crack was obtained.

本文用复变函数理论推导出裂纹的辅助场，并用Betti功互等定理给出求解混合型裂纹应力强度因子的远场围绕积分法。

This thesis is focused on the study of laser tracking control system, the key element of the measurement system.

论文主要围绕测量系统的一个关键部分—激光跟踪控制系统—进行研究。

It is, after all, well within the Greater London conurbation, usually taken to be the area enclosed by the M25 London Orbital motorway, which is on average about twenty miles from central London.

毕竟，这完全在大伦敦都市圈以内，通常是被M25号伦敦环线高速公路围绕的区域，那里平均起来距伦敦市中心大约二十英里。

Poincare\'s thought of philosophy of science has a bit messy, but the main focus is on conventionalism and Realism.

彭加勒的科学哲学思想虽然有点零乱，但主要还是围绕约定论和实在论展开的。

Some improved parameter estimation algorithms are presented , their convergent properties are proved by using the martingale convergence theorem .

围绕这两个方面给出了一些改进的参数估计算法，并用鞅的各种收敛理论对之进行了严格的数学证明。

This paper uses gradually convergent method and the content is based on the analysis of inherent mechanism.

本文的研究内容也正是围绕这一结构框架而展开的。

Has discussed the ambiguity surrounding the taxon Blanco described as Convolvulus distillatorius, and whether it was indeed identical with the one Merrill had before him when he made the combination Merremia distillatoria .

已经讨论围绕分类群的意义含糊布兰科描述成Convolvulus distillatorius， Merrill引用的标本在数个点具布兰科的原始描述里不同意。

The split between the two groups can hardly be papered over.
