by ordinary methods meaning in Chinese
- the speed of light being extremely great, we cannot measure it by ordinary method
由于光的速度非常大,我们不能用普通的方法度量。 - using the method of conversing double integrals into linear integrals, we obtain two theorems and their corollaries for double integrals of linear-fractional homogeneous functions with two variables, and construct some typical examples that are difficult to be calculated by ordinary methods to illustrate their applications
摘要通过把二重积分转化成曲线积分,得到二元分式线性齐次复合函数积分的两个定理及其若干推论,并构造一些比较典型的用一般方法难以计算的例子说明结论的应用。
