Calculated results by these formulas are very well in agreement with the results simulated by a digital computer. This shows that they can be used in PN code system design.
计算结果与计算机模拟的结果都很符合，因此可应用于PN码系统的设计中。
Both of these formulas basically relate work on a curve with what happens to the curl on the surface that is enclosed by this curve, that is bounded by this curve.
基本上，这两个公式把沿曲线的功，和被曲线包围的曲面上的旋度，联系起来了，曲面是以该曲线为边界的。
Now, so these are mathematical examples given by explicit formulas.
这些数学意义上的的例子，可以通过等式直接给出。
