使迁移

So inter-area migration becomes the leading pattern and main composing in interprovincial migration.

这使跨地带人口迁移成为省际人口迁移的主要模式和重要组成部分。

This paper presents the reasons for the continuing developments in the area of process migration , covers the major features of the process migration machinate and the problems in design , next , describes and evaluates the existing migration algorithms .

在分布式计算机系统中，进但由于进程运行中的改变，有时需要动态调整，程迁移有不少好处，这也是使它得以发展的重经即进程迁移。

By above research, the following results are obtained.(1)The extracting module of aero-radioactive thematic information is integrated with ENVI, the remote sensing image processing software;(2) Based on the IDL, the computer program modules extracting following uranium thematic information have been developed, including initial uranium contents, active uranium contents, uranium migration coefficient, uranium information strengthen, uranium D-value and variance Ratio etc, al. Some of kalium special information extracting modules are also developed;(3)Based on the IDL, the aero-radioactivity information multi-parameter focus analysis module is developed;(4) It is proposed that a lots of phenomenon of uranium immigrating exist in Keping-Kuche are in the Neocene period. Because of the uranium pre-enrichment, the areas with high uranium content were formed in Neozoic and Quaternary. The above migration uranium are also the abundant source for uranium ore-forming in favorable strata of Mesozoic and Cenozoic system;(5)There are obvious uranium immigrating and enrichment in Eastern Portion of Keping Block Uplift, Yinate-Laolongjiang, and Qidaoban-KuChe.

通过上述研究，取得了如下成果：(1)实现了航放专题信息提取模块与ENVI遥感图像处理软件的无缝集成；(2)基于IDL语言开发了初始铀含量、活性铀含量、铀迁移系数、铀信息增强、铀差值方差比等航放铀专题信息，钾专题信息提取处理程序；(3)基于IDL语言开发了航放信息多参数聚焦分析处理程序；(4)发现柯坪-库车地区在晚第三纪开始出现了大量的铀迁移富集现象，不仅使上第三系、第四系沉积时因铀的预富集而形成铀含量高场区，而且也为研究区中新生代有利目的层的铀成矿提供了铀源条件；(5)研究认为，研究区柯坪断隆东段，英阿特-老龙江，七道班-库车等三个区块存在明显的铀迁入富集。

The obtained potential energy curves disclosed that a four-state cycle existed in the ground and excited states. It was also found that the activation energy for the methyl transfer was higher compared to the phenyl transfer, which was consistent to the experimental results that the photoisomerization of the phenyl substituted derivative was more rapid than the methyl substituted derivatives.

对反应势能面的研究发现，在光异构化反应中化合物M21和M21、M31的基态和激发态虽然都可以构成四能级反应过程，但由于M21异构化过程的活化能较高，使其所构成的四能级反应难以进行，这就从理论上解释了迁移基团为甲基的M21变色性能低于迁移基团为苯基的M31的实验结果。

The human cartilages are composed of chondrocyte and extracellular matrix,the form of chondrocytes are hypertrophy and the quantity are less;the ECM of cartilage are compised of type II collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury,the ommilayer injury ofcartilage can be recovered by marrow,but because of without stimulation mechanism,the new tissues are merely fibrocartilages,they can not be coincide with hyaline cartilage in menchanics;the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation,thus,the plerosis of articular catilage can not depend on the proliferation of local chondrocyte.Ever since,people tried their best to find a way to reconstruct articular cartilage.

造成人体关节软骨损伤的原因主要为创伤和关节炎，关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复，但这种修复由于缺乏相应的刺激机制，只能形成纤维软骨，而不能形成符合关节生理、力学要求的透明软骨；单纯软骨部分损伤软骨组织内无血管，软骨细胞迁移迟缓，无法使损伤区域软骨细胞再生，因此，关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。

For the oxidation channel from OH group migration to O atom insertion,the activation energy barriers for OH migration are 58.4,65.3, and 79.2 kcal/mol,respectively,whereas those for O atom insertions beginning with directly destroying Si_a-Si_s backbonds by a foreign H_2O molecule are much lower,the respective values are 19.0,16.7,and 24.8 kcal/mol.

对于先经过OH迁移致使O原子插入Si_a-Si_s backbond的氧化途径，OH迁移所克服的能垒依次为58.4、65.3和79.2 kcal/mol，而H_2O以O原子进攻Si_a位来打开Si_a-Si_s键进而使O原子插入的能垒则相对较低，仅为19.0、16.7和24.8 kcal/mol。
