The surface - to - surface contact elements only support general static and transient analyses , buckling , harmonic , modal or spectrum analyses , or substructure analyses 下面一段又说面面接触单元支持模态分析,是否是其他分析的需要,而没有在模态分析中对接触单元进行处理
The paper had made the substructure soil liquefaction level decision formula which considered the stress of highway embankment , on the basic of final analyses results 根据研究结果确定了考虑公路路基应力影响的地基液化等级判定公式，同时对公路地基液化区域进行了划分。
But as an very ideal situation , hardy - weinberg equilibrium is not always suitable . for example , if we take the uncertainty which arise from population substructure it ' s not suitable 但是考虑到一些不确定性因素如人口子总体的情况，那么这时hardy - weinberg平衡不成立。
As an important part of metallic tps , the attachment must be strong enough to transfer mechanical load to the substructure and at the same time not much heat quantity 连接结构是金属热防护系统的重要的子部件,要求其在传递力学载荷同时,不能向机体传递过多的热量,对其研究具有重要意义。
The paper propounded that according to the different liquefaction lever and the different zone , man should planed an applicable treatment method on the highway substructure soil anti - liquefaction resolution 并提出，针对不同的液化区域和液化等级，采取相适宜的处理措施进行地基抗液化处理方案。
In this paper , many main functions such as mode analysis , optimum design , substructure analysis are combined in reason to meet precision , save ems memory , improve efficiency 本文把ansys的模态分析、优化设计、子结构等主要功能进行了合理整合，在满足精度的前提下，提高了工作效率，节省了机器内存。
Mssql substructure . provides a modular set of user , group , and object level permissions that function independent of the inherent mssql security . desigened to drop into any database aplication 该软件提供了独立于mssql自带安全机制的安全功能，提供了模块化设置用户、用户组以及对象级别访问许可的安全机制。
By adopting the layering foundation model , the contact element and the substructure method , the three - dimensional finite element analysis for soil , pile - raft foundation and frame - tube applied by the vertical loads is established 地基土采用分层地基模型，桩土界面采用接触单元处理，上部结构采用子结构法处理。
On the background of isolation system of a refrigerator compressor , a new mechanical model of the compressor was proposed , and applying substructure mobility approach , the formula of transmissibility of the isolation system was denied 摘要以冰箱压缩机隔振系统为背景，建立柔性基础双层隔振系统力学模型，运用子结构导纳法推导隔振系统传递率公式。
