大容量直接水冷汽轮发电机定子线棒由于电腐蚀可能会在水盒纤焊部位发生冷却水向对地绝缘泄漏的情况。一旦冷却水泄漏，由湿热引起的水解作用会加还线棒绝缘老化。因此为了安全运行和正确维护，有必要在早期检测出水泄漏。普通定子线棒绝缘只由云母带叠绕而成，还有另外一种结构的线棒，在线圈端部的对地绝缘中间层中夹有导电层（内部电极层）。内部电极层起分压作用，因此线棒端部表面电场得到了抑制。电容测量法普遍用于检测前一种结构线棒的潮湿情况。但这种方法不能应用于后一种结构的线棒。为检测后一种结构的潮湿线棒，我们开发了玫种新的灵敏的方法，简单介绍了我们在电容法方面的许多经验后，本文详细介绍了新开发的用于带有内部电极的线棒的方法。

What does it mean to study PDE (Partial Differential Equation)? How and what to do “to claim proudly that I’m studying a certain PDE”? Newton mechanic uses mainly ODE (Ordinary Differential Equation) and describes nicely movements of Sun, Moon and Earth etc. Now, so-called quantum phenomenum is described by, say Schrödinger equation, PDE which explains both wave and particle characters after quantization of ODE. The coupled Maxwell-Dirac equation is also “quantized” and QED (Quantum Electro-Dynamics) theory is invented by physicists. Though it is said this QED gives very good coincidence between theoretical1 and experimental observed quantities, but what is the equation corresponding to QED? Or, is it possible to describe QED by “equation” in naive sense?
