Had deafness not intervened, Beethoven might have become the very model of the modern orchestral conductor. From the technical point of view, his music invites control.
假如贝多芬的耳朵没有聋的话，他可能会成为现代管弦乐队指挥的一个典范。
Electrostatic shielding is provided by surrounding the signal path with a conductor connected to a low impedance point in the circuit, preferably the lo input terminal of the measuring device.
利用连接到电路中一个低阻点的导体，将信号通路包裹起来，即实现了静电屏蔽，该低阻点最好是测量设备的LO输入端子。
Edge Conditions can be used as criteria which must be obeyed by electric fields as they approach infinity at the local irregular point of a conductor.
可以采用边缘条件作为导体的局部非正则点处电场趋于无限大时应遵循的准则。
