查询词典 initial condition

Since the solutions of this problem are the critical points of the associated energy function. One generally needs some compactness such as PScondition or C-condition to prove the existence of critical points of the energy func-tion, but when we study the elliptic equation in R~N, the compactness condition does not always hold since the imbedding of the Sobolev space H_0~(1,2)into L~(2*) is not compact. In this chapter, based on the nonsmooth critical point theory, and by using the approximation technique with periodic function, the existence of nontrivial solution is obtained.

由于该方程的解就是其所对应的能量泛函的临界点，通常都要在一些紧型条件的基础上来证明其所对应的能量泛函临界点的存在性，但当我们在无界域上考虑该椭圆方程解的存在性时，Sobolev空间H_0~(1，2)到L~(2*)的嵌入非紧，从而导致所对应的能量泛函失去紧性，本章在非光滑临界点理论的基础上，应用周期逼近的方法证明该问题非平凡解的存在性。

According to the constraint condition request, modified Hungarian law is reaches basically the goal only by one step, at the same time, provide the all null elements which each line and each row need.,then check whether satisfy the constraint condition, otherwise must further make the zero.

匈牙利法的改进是根据约束条件的要求，基本上是一步到位造出每行及每列所需的零元素。然后检验是否满足约束条件，满足则可得最优解，否则需进一步造零。

Methods to rotor of centrifugal compressor"s condition monitoring and fault diagnosis are summed up. Peak-to-peak value is an essential reference value of centrifugal compressor"s condition monitoring, which is easy to implementation in practice. On the other hand, according to fault diagnosis, power spectrum and axis obit also works. The direction of eddyis gained from full spectrum, which is vital in fault diagnosis. In a word, to make sure make an exact conclusion, different method should be put in used.

总结了离心式压缩机转子振动的监测和诊断的方法：在压缩机的状态监测的方面，峰—峰值是其主要的手段，实践证明其实现过程非常简单而且非常有效；而对于故障诊断，常用的功率谱分析和轴心轨迹都有一定的作用，全谱可以判断转子的进动方向，所以在分析过程中可以综合以上多种方法，能更加明确故障原因。
