periodic reversal造句

1、A new computational scheme was developed to solve a three-dimensional model of a periodic flow reversal reactor by ADI alternating direction implicit method.(文中針對圓管式徑向?qū)ΨQ流向變換反應(yīng)器三維模型，利用交替方向隱式方法(adi)建立新的求解格式。)

2、If the Earth's magnetic pole reversal caused by biological extinction, it is not difficult to explain why from time to time, so that the periodic destruction of the Earth civilization.(假如地球磁極逆轉(zhuǎn)而造成生物大量滅盡，那就不難表明為何每隔一段時間，使地球文明周期性的毀滅。)

3、The existence and uniform boundedness of the global solutions of the model for sulphur dioxide oxidation in a tubular reactor with periodic flow reversal are proved by the invariant domain method.(利用不變區(qū)域方法，證明了二氧化硫催化氧化管式反應(yīng)器流向變換強制操作模型整體解的存在性和一致有界性。) [hao86.com好查]

4、The reversal process is not literally periodic as it is on the sun, whose magnetic field reverses every 11 years.(倒轉(zhuǎn)過程不是真正具有像在太陽上那樣的周期性，太陽磁場每11年出現(xiàn)倒轉(zhuǎn)。)
