级

When restoring incremental backups, RMAN uses the level 0 backup as the starting point, then updates changed blocks based on level 1 backups where possible to avoid reapplying changes from redo one at a time.

当从增量备份恢复的时候，RMAN用0级备份做为起始点，恢复改变的数据块依靠1级备份，这样避免了在同一时间从重做日志恢复两次。

In consideration of human hearing system′s frequency selectivity,the effects of thickness of coupling plate on critical-band level were also explained.

在考虑了人类听觉对频率的选择性接收的前提下，研究了参与耦合的板的厚度对特征频带声强级的影响，讨论了从特征频带声强级到响度的转换过程。

Consider an R-C coupling mechanism from plate of one stage to grid of the next stage. What is the frequency response?

让我们考虑一下从一个放大级的屏极到下一个放大级的栅极的 RC 耦合，它的频响会是怎么样的呢？

In the end, in order to prove the credibility of what she proposed, the instructor showed a list of names and phone numbers of her previous prentices so that we can confirm the outcomes of her training. She also added that all of her prentices who passed level 10 learned clarinet from scratch. If my son can follow her learning plan, she guarantees him passing level 10 in five years.

最后，为了证明自己所言无虚，老师拿出了历年来自己培养的弟子的名单和电话，供家长查证，老师还补充说，所有这些取得10级证书的孩子，都是从零开始学习的，如果你的孩子想学的话，在5年达到10级水平完全没有问题。

As a preamp it is at least as good as any $3000 preamp I've ever heard.

作为前级它最少可以比美我听过的任何3000美元的前级。

The preamp (or preamp stage of an integrated amp) is next in importance.

前级放大器或集成放大器的前级）是其次重要的。

The system consists of power supply circuit, circuit-level preamp, power amplifier circuit, output stage components.

该系统由电源电路、前置放大级电路、功率放大电路电路、输出级组成。

A two cell SBS phase conjugating mirror pumped by pulsed Nd∶YAG laser was experimentally investigated. After returned to YAG amplifer and coupled out by a polariser, SBS output beam had the characteristics of duration tunability and good quality with near diffraction limited far field divergence angle.

对脉冲Nd：YAG激光器抽运的双池受激布里渊散射相位共轭镜进行了实验研究，将相位共轭镜后向反射光束馈入YAG放大级，经放大级放大，由偏振片耦合输出的激光束具有高质量、脉宽可调的特点，远场发散角接近1倍衍射极限。

After particle distribution analysis and test of penetration of oil perforation to steel target,the influence of particles arrangement and distribution of powder shaped charge liner on performance of jet was studied and the liner was treated by thermal treatment.

利用筛分法，将127型石油射孔弹药型罩中的铜粉进行颗粒分级，并与其他金属粉进行粒度级配，通过粒度分布分析及射孔弹侵彻钢靶试验，研究了粉末药型罩中金属颗粒的粒度级配及分布对聚能射流性能的影响，同时对药型罩进行了热处理研究。

Keeping this in mind, a study was undertaken to determine the effect of CA on early growth of mung bean (Phaseolus aureus=Vigna radiata), morphogenetic response in hypocotyl cuttings of mung bean, and changes in the activities of some associated enzymes – proteases, polyphenol oxidases, and peroxidases – and endogenous total phenolics at root initiation (third day; 48 h; appearance of root primordia; RI), root expression (fifth day; 120 h; appearance of roots; RE), and post-expression (seventh day; 168 h; PE) stages of rhizogenesis.

保持这一点，一项研究，以确定影响钙对早期生长绿豆（ phaseolus金黄色葡萄球菌=豇豆拉迪雅塔），形态发生反应，下胚轴插条绿豆，和变化，在活动的一些相关的酶-蛋白酶，多酚氧化酶，过氧化物酶-和内源性总酚的从根本上启动（第三天； 4 8小时；外观根原基；里），根的表达（第五天； 1 20改为H级；外观根；转口），和后表达（第七天； 168改为H级； PE ）的阶段rhizogenesis 。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
