其实,坦克这种超常的“本领”,是由导体的电学特性所决定的。现代主战坦克的车体、履带,都是由钢铁制成的,又宽又长的两条履带,成了良好的接地点,坦克的身躯,也就成了一个接地的空心导体。根据物理学上的静电屏蔽原理,一个接地的空心导体,外界的电场不会影响腔内的物体。因此,当坦 In fact, the extraordinary “feature” of tanks is determined by the electrical properties of the conductors. The bodies and caterpillars of modern battle tanks are all made of steel. The wide and long caterpillars have become a good grounding point. The body of the tank has become a hollow conductor for grounding. According to the principle of electrostatic shielding in physics, a grounded hollow conductor, the external electric field will not affect the cavity of the object. Therefore, when Tan
