      <\/span>1)上圖中的電路用來產生脈沖電壓，所用元器件數值見下表，電容器<\/span>C<\/span><\/span>_{1<\/span><\/sub>起始狀態被充電壓<\/span>Uc。<\/span>10/700μs<\/span>（<\/span>10μs<\/span>為視在波前時間，<\/span>700μs<\/span>為視在半峰值時間，其波形見圖<\/span>9<\/span>所示，<\/span>T<\/span><\/span>1<\/span><\/sub>為視在波前時間，<\/span>T為視在半峰值時間）的脈沖試驗電路是用來模擬通信網絡中的閃電干擾。<\/span><\/span> <\/span>
      <\/span>2）<\/span>1.2/50μs (1.2μs<\/span>為視為在波前時間，<\/span>50μs<\/span>為視在半峰值時間，其波形見圖<\/span>9<\/span>所示<\/span>)<\/span>的脈沖試驗電路是用來模擬配電系統中的瞬態電壓。<\/span><\/span> <\/span>
