The work - loss exposure increases with each update until the next full backup , when the work - loss exposure returns to zero and a new cycle of work - loss exposure starts 備份僅包含數(shù)據(jù)庫(kù)中的實(shí)際數(shù)據(jù),而不包含任何未使用的空間,因此,備份通常小于數(shù)據(jù)庫(kù)本身。
The dc / dc converter provides pulse voltage , which returns to zero periodically , for the devices in the inverter to realize zvs . but the devices still have some on - loss under two kinds of state commutation . therefore , it is better to use the devices with smaller junction capacitor 通過對(duì)逆變橋工作模式的分析,發(fā)現(xiàn)在兩種模式轉(zhuǎn)換的過程中功率管開通時(shí)存在一定的損耗,據(jù)此認(rèn)為逆變橋功率管應(yīng)采用輸出電容小的器件。
return to zeroとは意味:《コ》ゼロ復(fù)帰◆【略】RZ return to zero meaning:[Electronics] 1. Abbreviation RZ or RTZ. In the magnetic recording of data, a method in which the write current returns to zero following the write pulse. Compare NONRETURN-TO-ZERO. 2. A logic system...
