它可以表达定义在平面上非规则三角形参数域中的任意复杂的几何形状。 - We study the global qualitative analysis depending on all parameters , and get the partition of parameter space
本文从全参数角度对系统( 1 )进行全局定性分析，得到参数域的剖分，给出参数在不同参数域时的全局动力学性质。 - The nonlinear electromagnetic force may cause the large oscillations of the rotor in some parameter regions . thus , the studies on the properties of the nonlinear dynamics and the stability for the rotor - ambs system play an important role in the engineering
非线性力的作用使转子在某些参数域中产生相当大的振动，因此分析该类系统的非线性振动特性和稳定性一直是电磁轴承-转子动力学研究的重要课题。 - By pre - dividing parametric region of the surface and introducing the concept “ maximum absolute normal curvature ” at a point on the surface , the method adopts “ divide and conquer ” approach triangulating the parametric region of the surface piecewise
该算法通过对曲面的参数域进行预剖分，以及引入曲面上一点处的“最大绝对法曲率”的概念，采用“分而治之”的方法分片对参数曲面的参数域进行三角形网格剖分。 - The structural dynamic sa in project is of great importance for the study on dynamic design , optimization design , control theory and dynamic modification etc . and direct method , difference method and perturbation method for dynamic sa are adopted regular , though following shortages are obvious : only local impact of the factors on the model can be obtained ; model dependence ; the interval is usually the same for all of the variables and is not related to our degree of knowledge of the variables ; shortage of precision and so on
工程结构的动态特性灵敏度分析对工程结构的动态设计、优化设计、控制理论和动态修改等方面的研究有着十分重要的意义。目前，结构动态特性灵敏度的分析法一般采用局部法，如直接法、差分法和摄动法。但是这些方法只能求参数域某点的灵敏度，不仅受模型、计算精度的限制，而且二阶以上的灵敏度求解比较困难。
