And the technology also plays a vital part in research into the human genome : the synchrotron is used to reveal the three - dimensional structures of proteins in the genetic blueprint , helping scientists to develop effective drugs 另外，同步加速器技术还在深入研究人类染色体组织的科学领域扮演着关键的角色：利用同步加速器可以显示出遗传基因图谱中蛋白质的三维结构，有助于科学家们研制出更有效的药物。
However , until now , most of the traditional ict facility can only get the 2d information which might be very limited to determine the perfect spatial location and the exact area of the details . therefore , there is a need to reconstruct 3d images 通常情况下，工业ct扫描只能得到某一断面上的二维信息，不能得到被检测物的整体描述，技术人员只能根据获得的系列二维图像在人脑中综合复原为三维结构。
By using the attenuation property of the rayleigh surface wave to invert the quality factor of crust and upper mantle , this paper yields the s - wave quality factor 3d structure of crust and upper mantle of china , and the viscidity structure of this area as well 本文主要通过rayleigh面波衰减反演地壳上地幔s波品质因子q _ ，建立了中国大陆地壳上地幔s波品质因子全三维结构。探讨了中国大陆区域地球内部粘弹性结构。
We develop report form system as the form of expression of data . the main characteristic is that use one three - dimensional structure display financial theme multidimensional structure , which offering the decision support of data based on financial statement to financial affairs policy - makers 我们自行开发的数据表现形式? ?报表系统，主要特点是应用一个三维结构表现财务主题的多维结构，为财务决策人员提供基于财务报表的数据决策支持。
Algorithm above has been implemented in finite element program ddj - w , and can analyze non - linear random response of 3 - d structure which has complex boundary conditions under earthquake excitation . practical bridges of engineering are calculated and the results are reasonable 以上的算法已在有限元分析软件ddj ? w中实现，可以处理具有复杂边界条件的三维结构在地震激励下的局部非线性随机响应分析，并计算了工程中的实际桥梁，得到了比较合理的结果。
The initial model ( vs , vp , qb , p ) based on previous work of this research group is adopted , and by terms of the relationship between the attenuation factor and s - wave quality factor , the stochastic least square is conducted to inverse the o > > of ail layers under every grid , i . e . the qb structure of every uiut - column Q _ 、 p ) ，利用衰减系数和层内s波品质因子q _之间的关系，通过阻尼最小二乘法反演方法反演每个单元格内各层q _ ，得到每个“单元柱”的q _三维结构
This is of very important significance to understand the material property and geodynamic of corresponding area , , the surface wave attenuation mechanism and the inversion algorithm of attenuation and s - wave quality factor are discussed systemically in this paper . some important fruits and understanding are resulted from the the crust and upper mantle tomography of china . ( 1 ) calculating of the rayleigh surface wave attenuation factor y 本文首先探讨了面波衰减的机理，对面波衰减和s波品质因子q _反演的计算方法进行了系统的研究，并对中国大陆地区地壳上地幔q _三维结构进行层析成像，取得了以下重要成果： ( 1 ) rayleigh面波衰减系数计算。
This paper , based on the related research on previous studies of firm theories and strategic management , provide a fresh and comprehensive analysis on the knowledge strategic manangement of knowledge - based firms through the systems engineering theories and methodologies , which can enhace the understanding and can provide new ideas both for researchers and practitioners in this field , the main contributions of the paper as the following : firstly , the author argues that firm is a complex knowledge system , firm strategy is a process of knowledge creation and knowledge application , and the untimate target of innovation is to create knowledge avantage for firms , and provids a comprehensive analysis for firm stategy according to systems engineering 其研究的主要内容如下： ( 1 )本论文认为企业是一个复杂的知识系统，首次提出企业战略是一种知识活动，知识创新过程是以提高企业知识优势力为目标的，并试图用系统论的观点对知识型企业的战略管理进行解读，弄清楚知识型企业战略管理思想的合理内核。在此基础上，对知识型企业战略系统的核心问题进行分解，构筑以知识为中心的“共同愿景?知识流程?知识员工”战略模式、以知识优势力为核心的战略系统三维结构和战略管理过程三阶段相结合的分析框架。
Comparative advantage of international trade is a three - dimension structure , that is to say , an ultimate coagulation of such three elements as structural advantages of national production factors , structural advantages of trade commodities , consistency that exported commodities are in line with other nations " consumption structure 国际贸易比较优势，是一个与一国文化禀赋优势可持续发展相关联的动态三维结构，或者说，是一国生产要素结构优势、贸易商品结构优势、提供物与他国居民消费结构的一致性等因素的综合体现。
