计数器

• This is a straightforward approach that can make a binary counter count to any number .
  这是一个利用二进制计数器计任意数的简捷方法。
• Counters can, of course, be made highly directional by the use of external collimation .
  当然可以利用外部准直法来提高计数器的方向性。
• It is possible, though not usual, to renovate an exhausted counter by refilling it .
  通过重新充气，可以使一个不能用的计数器复原，但通常不这样做。
• It is possible, though not usual, to renovate an exhausted counter by refilling it .
  通过重新充气，可以使一个不能用的计数器复原，但通常不能这样做。
• Ring counters should be always preset because without presetting their operation is undermined .
  环形计数器必须进行预置，否则其工作状态是不正确的。
• The instrument consists of a long, narrow bf3 counter surrounded by a paraffin cylinder .
  这台仪器包括一个细而长的BF3计数器和围着的一个石蜡圆柱形筒。
• Since the above inequality is not satisfied a serial-carry synchronous counter can not be used .
  因上述不等式不能成立，所以不能采用串行进位同步计数器。
• It should be noted that at the beginning of their operation the feedback counters must be cleared .
  我们必须注意，反馈计数器在开始工作前，必须首先清除。
• For proper operation the forward and reverse direction-control inputs must always be complementary .
  要使计数器正常工作，正向和逆向控制输入电平必须始终相反。
• It uses binary counters for the conversion of the multiplicand from parallel to pulse-train form .
  它采用二进制计数器以把被乘数由并行形式转换成脉冲序列形式。
