  4. This isi series oscillation has following characters : ( 1 ) long term cycle duration, whose duration of most oscillations ranged from 3 0 - 120ms, so we called it slow wave oscillation ; ( 2 ) large amplitude of oscillation, the minimum isi is about 2ms while the maximum is beyond 40ms, which suggested that the firing frequency vary from several tens to hundred hz ; ( 3 ) abrupt turn always occurs during the continuous change in isi, this turn is called inflexion temporarily

    該振蕩波有下述特徵： （ 1 ）振蕩周期較長，多數在30 ? 120s范圍，故稱慢波振蕩； （ 2 ）振蕩幅度較大，其isi振蕩最小值在zms左右，最大值可達40ms ，表明放電頻率可在幾十到幾百k范圍內變動； （ 3 ）在isi連續變化過程中往往出現突然轉折，暫稱其為拐點。

  6. Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly - varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, in hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed

    若這些海上建築物的上部結構底高程較低，在惡劣海況下當大波浪在其面板下面通過並與之接觸時，面板下面除了作用有強度變化較緩慢的波壓力外，在波峰剛接觸到面板時尚存在著歷時很短但強度極大的沖擊壓力，這種極強沖擊荷載會引起建築物的整個上部結構失穩或造成局部破壞。
