  1. Meanwhile it can filter the waveform and gather the envelope and calculation the current peak and max steepness of lightning by length of erased magnetic record. thirdly we need analyze the difference of length of erased magnetic record between kinds magnetic tape or pre - recorded sine wave on magnetic tape, and finding the min and max lightning current that can be recorded by magnetic tape. then we confirm the type of the magnetic tapes and the way of installing which fit to the line towers

  2. By means of this index this paper analyzes the gentleness of the peak ’ s slope for the four normally used envelope functions and some of them have been modified

    文中據此對四種包線函數的平穩度進行了分析，還對某些包線函數提出了一些改進。
  3. The evaluation has been made for normally used four envelope functions of earthquake ground motion. being as evaluation standard of the envelope function this paper pointed out that the controlling capability of the parameters involved in functions of the peak position of the envelope with single peak and the shape of the envelope are essential besides simplicity of the formula of envelope function

    本文對已經提出的四種經常使用的包線函數模型進行了評價，認為對于評價單峰點包線函數，除了要求形式簡單以外，其優劣可以用函數對峰點位置和高峰隆起程度的控制能力作為標準。
  4. Abstract : a method by using 8031 single - clip microprocessor to get the syntonical bit information is presented, based on the characteristic of the modulated singal in ascending cosine envelope. the timer is locked at the maximum of the wave peak. the experiment results indicate that this method is feasible for 2 400 bps system

    文摘:利用升餘弦包絡調制信號的特點，即基帶信號為升餘弦波，接收端可以利用這一包絡，從中提取定時信息.提出了一種將時鐘鎖定到包絡峰值最大點的單片機實現的方法，從而完成了在接收端正確提取定時信息的任務
