工程近似 meaning in Chinese

engineering approximation

Finite element method ( fem ) is an approximate solution in engineering , there exists some error in the analysis result , so it is important to check the result and to geta right view of the result in the analyzing process , then this can lead the right analysis in the next step
摘要有限元法是一种工程近似求解的方法，存在误差，所以在用有限元软件进行工程分析计算时，很重要的一点是分析过程中必须审视分析的结果，对结果有正确的认识，从而指导工程分析的正确进行。
The approximate formulas for calculating the sdrs were deduced , and the relation among the sdrs of those arrays was obtained ; then the effect of the mutual coupling on the sdrs was analyzed , the analysis result is that mutual coupling has no or small effect on the sdrs and the explanation for the result was also given ; finally , the sdrs that were attained by use of computer simulations and approximate formulas were compared
推导出了三种二维阵列结构的空间方向分辨率的工程近似计算公式，并得到了它们之间的关系；分析了阵元间的互耦对空间方向分辨率的影响，得出了互耦对空间方向分辨率没有影响或影响很小的结论，并对该结论进行了解释；对由工程近似计算得到的空间方向分辨率和计算机仿真得到的实际的空间方向分辨率进行了比较，指出了工程近似计算公式的局限性。
