The results show that in the later stage of the nucleation process, the maximum slip velocity is monotonically accelerating ; the slipping hot spot ( where the slip rate is maximum ) migrates spontaneously from a certain instant, and such migration is spatially continuous ; when the maximum velocity reaches a detectable order of magnitude ( at least one order of magnitude greater than the loading rate ), the remaining time is 20 hours or more, and the temporal variation of slip velocity beyond this point may be used as a precursory indicator ; the average slip velocity is related to the remaining time by a log - log linear relation, which means that a similar relation between rate of microseismicity and remaining time may also exist ; when normal stress variation is taken into account, time scale of such processes can be extended by about 2 times
結果表明，在成核的後期階段：最大位移速率單調加速增加；滑動熱點（最大滑動速率處）在後期階段開始自發性遷移，且在空間上連續；當最大滑動速率達到可以明顯探測的量級時（高於載入速率一個數量級以上） ，倒計時間為20小時或更長一些，這時的速率變化可作為臨震預測標志；平均滑動速率與倒計時間的關系在臨震階段呈對數線性趨勢，由此可推測微震活動增長率與倒計時間同樣存在對數線性關系；正應力的變化對上述時間尺度有延長作用，使之大致增加到原數值的2倍。
