forward recovery time 中文意思是什麼
forward recovery time
解釋
正向恢復時間-
The researching results indicate the reverse recovery characteristics of the device are much improved : the reverse recovery time is remarkably shorted, the peak reverse current is notably reduced and the soft factor s is also increased in various degrees but not notable changed in forward drop when introducing the two kinds of novel structure
結果表明，採用新結構后，反向恢復特性大大改善，恢復時間明顯縮短，軟度因子s顯著提高，反向峰值電流也有不同程度的降低，其綜合性能遠遠高於si同類型結構及常規p ~ + （ sige ） - n ~ - - n ~ +二極體。 -
When a user drops a table in db2 udb, you can either do a database level point - in - time recovery, rolling forward to the point before the table is dropped ; or, better still, use a table space level roll forward operation
當用戶刪除db2 udb中的表時，您可以執行數據庫級時間點恢復，前滾至刪除表之前的時間點；或者最好仍然使用表空間級的前滾操作。 -
The sample with low emitter efficiency has completed as the method of above. this lead to the greatly decrease of the reverse recovery time and the low reverse leakage and forward voltage, especially the excellent temperature character of the leakage. the test date shows that the samples reach the first class of international level
本論文作者通過模擬測試，驗證了課題研究的理論設想，並設計製作了具有低陽極發射效率結構的高壓功率frd ，利用局域鉑摻雜和電子輻照相結合的壽命控制方式，實現器件反向恢復時間的極大減小，並且反向漏電流、軟度因子、正向壓降等關鍵參數也較理想，且具有極佳的漏電溫度特性，達到器件綜合性能的優良折衷，達到國際先進水平。 -
A non - linear feed - forward loop is used to realize the coordinated control between the two controlled variables at the two control ends at first. secondly, a constant ac voltage control is implemented for a short period after the ac fault removal. finally, a staggered recovery strategy for different hvdc subsystems is also adopted, with the restart time interval of them optimized using the steepest descent gradient search method
該協調恢復策略的三個特點是：在常規的控制器結構中加入一個基於準穩態工作點的非線性前饋迴路；在交流故障被切除后的一個短暫時間內，逆變側採用定交流電壓控制：對不同的直流輸電子系統採取一種漸進的恢復策略。 -
Forward recovery time
正向恢復時間 -
If you choose to have archive logging, and do an online backup and roll forward recovery, you can recover to a point in time or to the end of the logs for the minimum loss of data
如果您選擇使用歸檔日誌記錄，並執行聯機備份和前滾恢復，那麼您可以恢復到數據丟失最少的那個時間點，或者恢復到結束日誌的時候。 -
Sql server estimates how many data modifications it can roll forward in the recovery time interval
Sql server將估計有多少數據修改可以在恢復時間間隔中前滾。 -
Sql server typically issues a checkpoint in a database when the number of data modifications made in the database after the last checkpoint reaches the number sql server estimates it can roll forward in the recovery time interval
通常情況下，如果自上次檢查點執行以後數據庫中所做的數據修改數量達到了sql server所估計的可以在恢復時間間隔中前滾的修改的數量， sql server將在數據庫中執行一個檢查點。 -
You can either use a copy of your backup image and roll it forward to the time right before the table was dropped point - in - time recovery, or you can restore a logical backup through the exp utility
您可以使用備份映射的副本，並將它前滾至刪除表之前的某個時間點（時間點恢復） ，或者您可以通過exp實用程序恢復邏輯備份。
