You can see that each ring in the multi-polygon is transformed to a single sub-path in SVG, started with the m control character and terminated with Z to close the ring.
可以看到，多多边形中的每个环都被转换成s VG中的一个子路径，每个环以控制字符m开始，以Z结束。

Similarly, in DB2 z/OS, there are different types of traces that will run at sub-system level to collect information that you normally require for monitoring and performance tuning.
I'm going to prove that the flux of a vector field that has only a z component is actually equal to the triple integral of, RzdV well, the divergence of this is just R subz dV.
