To get its seismic property of annular cable - truss structure without support , time history analysis is done to show that it is not effective to control the seismic property with modifying the magnitude of pre - stress 为了考察结构的抗震性能，本文对不加支撑的内外都是圆形的结构进行了三维地震作用下的非线性动力响应时程分析。
Although light waves in the regime of classical optics can have electric fields as strong as those near bolts of lightning , these fields are not effective for accelerating particles on their own , because they oscillate transversely 在古典光学中，虽然光波的电场有可能大到如闪电雷击的程度，但因为电场是以横向振荡的，所以无法有效用来加速粒子。
This paper includes 1 . the author revised the original data by data generation . gm ( 1 , 1 ) is suitable for the monotone series very well , however , it is not effective for oscillation series , and the prediction time is so short ( l - 2 second ) 由于灰色系统gm ( 1 ， 1 )模型适用于单调增加数列，对于振荡数列则不很有效，即使用于预测也只能预报很短的时间( 1秒) 。
Since most algorithms are not effective and not very meaningful in combining , this thesis proposes an algorithm based on a kind of semi - naive bayesian classifier which is measured by conditional mutual information ( cmi - bsnbc ) 针对已有的学习算法中存在的效率不高及部分组合意义不大的问题，本文提出了条件互信息度量半朴素贝叶斯分类学习算法( cmi - bsnbc ) 。
The conventional methods of edge detection have good effect on clear image , but are sensitive to noise . though mallat used multiresolution wavelet to detect edge of noisy images , it was not effective for much noisy image 传统的检测方法对清晰图像的边缘检测效果很好，但对噪声相对敏感，尽管mallat用多尺度小波变换来压制噪声，可是对于有大量噪声的图像，边缘检测效果并不好。
The performance test also showed that paractive still cannot fully meet the requirements for practical application , due to the lack of enough inter - procedural analyzing ability . parallelization for certain user cfd programs is not effective 通过测试也发现了paractive系统离实用要求还有相当距离，对源程序限制过多，缺少过程间分析功能，因而对用户cfd程序的并行化不是都能奏效。
The other method is pontryagin maximum value principle dealing with low thrust control problem . however when the system is very complex , especially when the system contains uncertain factors , the method is not effective 但在多指标的要求下，这种方法难以求得最优解；另一种方法是应用pontryagin最大值原理解决有限推力最优控制问题，但对复杂的或者含有不确定因素的系统往往难以奏效。
Through the utilization , it can produce stronger sheathing action . what ' s more , because the structure is simple , beautiful and economical , it has well economic and technology value . now , the design of the structure is not effective and the research is behind the times 这种组合结构能充分挖掘岩土体自身潜力，并产生强大的挡护作用；加之其结构简单，自重较轻，节省材料，有良好的经济技术价值。
Although admittedly a number of foreign countries have implementing a quota system for employment of people with disabilities , through our research , we understand that in many cases the system has limitations and is not effective in promoting of employment opportunities of the disabled 虽然一部份海外国家的确已经实施残疾人士就业配额制度，但经研究后，我们发现在很多情况下，这种配额制度对促进残疾人士就业效益不大。
The most important of this part is to explain definitely the publicity principle , which means assignment of real right is not effective without publicity . it sets a target for this thesis and also provides precise basis for criticizing the publicity principle in “ draft of real statute ” 在此部分,最重要的还是对公示原则作明确的界定,即不经公示不能生物权变动效果,为本文树立明确的靶子,也为批判《物权法草案》中的公示原则条款提供精确的依据。
