By definition, the guard terminal is nearly at the same potential as the high impedance terminal, so the guard terminal will be at the same potential as the magnitude of the voltage source.

根据定义，保护端与该高阻端处在几乎相同的电位，所以保护端就与电压源为相同电位。

The sizes of epidermis cell, the lengths of stomatal guard cells and of the terminal cells of T-hair are only quantitative characters, but not of much significances in systematics.

表皮细胞的大小、气孔的保卫细胞长度和T 型-毛的顶端长度等，这些只是数量特征，在本族分类上意义不大。

Note that when none of the channels on the Model 7158 card are energized, terminals 2 and 4 are connected to the LO of the picoammeter (pA), which electrically is the guard terminal.

注意，当7158型开关卡上没有通道被激励时，端子2和4是被连接到皮安计（pA）的LO端子的，它在电气上为保护端子。
