I had to wear a patch after the initial surgery, for about one day.
手术后我必须戴一天的眼罩。
Thus, the wear depth estimation could potentially include the initial nonsphericity.
然而,因此磨损测量的深度可能潜在的包含了最初的误差。
The contact voltage drop was low in the initial stage of wear, then rose to a certain level, finally became stable.
结果表明:在电磨损初期接触电压降较小,随着时间延长,接触电压降上升并趋于稳定;
