The method of crack - division is used to make radial cracks at the edge of cavity . a series of integral equations for determining the dsif at tips of anti - plane crack are set up in terms of the green ' s function 按“契合”的方式和采用裂纹切割技术构造出孔边径向界面裂纹对sh波散射的模型，利用green函数建立直接求解m型裂纹尖端动应力强度因子的定解积分方程组。
This phenomenon farther surport our conclusion in the analysis of evolution stars , i . e . the difference of stellar chromosphere and corona activity of evolution stars is bred by the energy balance and heating mechanism in stellar chromosphere and corona M型主序星在演化恒星的冕球活动与色球活动行为的差异则是由于m型主序星的色球与冕球间存在的能量平衡和转移过程产生的。
The result of statistics show the ratio of strong activity samples in m type ms stars is larger than that in other g , k type ms stars , the relation of between angle momentum and magnetic momentum of m type stars also depart from the whole relation of ms stars 主序星的角动量与以冕球活动指数为指标的磁动量间的相关性分析表明m型主序星的角动量与磁动量间的关系偏离了其它类型的主序星的总体线性关系。
M - mode is a kind of dynamic display mode . it also uses the brightness to represent the strength of the ultrasonic returns , but the independent variable in the display is time . returns from different scanned depths are revealed along the time axis to show the movement of different layers of the scanned organs M型是一种运动显示方式，它也是以亮度的强弱来表示回声信号强弱，但将声束路径上不同深度的回波图象沿时间轴慢慢展开，以表示界面的运动轨迹。
Experimental results confirmed this assumption : during the interstimulus interval ( isi ) ranged from 33 to 83 ms , with the isi luminance approximated to the mean luminance of the stimulus grating , a novel okn elicited by the intermittent display of stationary gratings was observed and recorded . it can be labeled as " intermittent - display - grating induced okn " ( idg - okn ) . in the second part , considering that the biphasic visual impulse resp onse is the feature of the magnocellular ( m - cell ) pathway , and the m - type ganglion cells are damaged in the primary open - angle glaucoma ( poag ) , we presumed that idg - okn of poag could differ strikingly from that of normal subjects 结果显示，当间歇刺激间隔( interstimulusinterval ， isi )在33 83ms范围内， isi期间亮度近似为刺激光栅平均亮度，我们观察并记录到这种新型的静止光栅诱发的oknintermittent - display - gratinginducedokn ( idg - okn ) ( magnocellular )路特性，而且原发性开角青光眼( primaryopen - angleglaucoma ， poag )是m型视网膜神经节细胞受损，因此我们推测，基于双相视觉脉冲反应的idg - okn在poag病人与正常人比较中很可能出现显著差2间歇刺激，对11只poag眼和14只正常眼进行对比眼动实验。
Studies on karyotypes wihin clones indicated that all the karyotypes belonged to stebbins ' 3b type . there are different karyotype formulas , polymorphsim of satellite chromosome , variations of chromosomal structure and b - chromosome in clones . chromosomal mutation is important factor of chromosomal structure variations within clones 无性系内核型研究表明：各无性系的核型类型都属于st吮七us的m型、核型公式不完全川同、随体染色体具多忐性，染色体存在结构变异，研究认为造成无性系内核型变异的重要原因是染色体突变。
On the base of reality , and by taking the civil soe as research object , the thesis makes a theoretical and practical study on the transformation of soe orgnization structure . the first part of the thesis analyses briefly the new situation soe facing with , introduces the process of two transformations of western enterprise orgnization structure , and the present situation of soe orgnization structure and the reasons of transfomation ; then the thesis elaborate the theory basis of the transformation of orgnization structure ; in section iii . it introduces a few typical cases of the transformation of orgnization structure , in section iv . taking zhuzhou cemented carbide group corp . ltd 文章首先分析了国有企业面临的新形势，介绍了西方企业两次组织转变的历程和我国国有企业组织结构的现状及变革的动因；接着阐述了组织结构变革的理论基础；第三部分介绍了几个典型的组织结构变革案例；第四部分以株硬集团公司为例介绍了集团公司采用改进后的m型组织结构的设计和分析；最后指出了组织结构变革需要注意的几个问题，得出了国有企业组织结构变革没有统一的模式，需要灵活采用m型组织结构的结论。
Secondly , we present the set of nonlinear partial differential equations that describes the wave - particle interaction , by analyzing the output power spectrum , the limit cycle and chaotic oscillation of the radiation field in the traveling wave tube ( twt ) amplifier and the magnetically insulated transmission line oscillator ( milo ) are studied numerically , respectively 接着，在论文的第三章和第四章我们从导出了一组用于描述场和电子相互作用的非线性偏微分耦合方程组开始，利用频谱分析法，以行波管( twt )放大器和磁绝缘传输线振荡器( milo )为例，数值研究了o型器件和m型器件中场的极限环振荡和混沌行为。
The work in this thesis is based on the combination of medicine - ultrasonics and the image processing . with the computer as an platform , several kinds of processing were conducted on the b images of hearts captured in clinic , such as image enhancement and edge detection . and pertinent information from the b images were extracted and used in synthesizing the m images of the heart in arbitrary directions 本论文将医学超声学与数字图象处理两门学科结合起来，以计算机为平台，利用数字图象处理方法，对心脏的b型图象进行了图象增强、边缘边检测等处理，并从b型图象上提取出相关信息，合成了全方位的m型图象。
Which will eventually form stars of spectral types g , k or m . t tauri stars are surrounded by a huge cloud and they are very young , with low surface temperature . they emit most of their light in the infrared region and they appear red . a general principle is , a violent reaction will give out short wavelength waves , like gamma rays or x - rays ; while a gentle process will radiate long wavelength waves , like radio or infrared ，这类星最后会演化为g k或m型恒星，金牛座t型星为表面温度低而非常年青的恒星，四周被星云所围绕，所以这种星颜色偏红，较容易在红外线波段找到一个普遍的原则是，如果活动越激烈，则所放出的光波波长越短，主要会为伽玛或x射线如果活动温和，则会发放出如无线电波或红外线等长波长电磁波。
