有功的

How many things are there which a man cannot, with any face or comeliness, say or do himself A man can scarce allege his own merits with modesty, much less extol them; a man cannot sometimes brook to supplicate or beg; and a number of the like.

还有，有多少事是一个人为了颜面底关系，不能自己说或办的！一个人不能自承有功而免矜夸之嫌，更不用说是不能表扬自己底功绩了；他有时也不能低首下心地去有所恳求；诸如此类的事很多。

This thesis has analyzed the movement mode of syntony electrical network of neutral point after the quenching of arc coil grounding, studied and analyzed the selective leakage protection principle based on the zero sequence active power.
