电荷

• On the way they will be deflected by the electric field due to the charges within the atoms .
  它们沿途由于受到原子内部电荷的电场作用而发生偏转。
• The boundary of the charge region for a proton is not sharp like the surface of a billiard ball .
  质子电荷飞域的边界并不象弹子球的表面那样分明。
• Some of these positive charges are then satisfied by electrons blowing in from wire b .
  然后，这些正电荷中的一些电荷由从导线B流入的电子得到补偿。
• Since neutrons have no charge, they produce no ionization in their passage through gases .
  因为中子没有电荷，所以它们在经过气体时不产生电离作用。
• In the present chapter we shall assume that the charges or conductors are in otherwise empty space .
  在这一章里，我们将假设电荷或导体都在真空中。
