定时的

In alternating current the motion of the charges is periodically reversed; in direct current it is not.

在交流电中，电荷流动会定时的反向，而在直流电中则不会。

As a child often irregular脐周minor abdominal pain, accompanied by weight loss, poor appetite; or like to eat dirt, slag and other bad habits, it should be highly suspected ascariasis.

如孩子常有不定时的轻微脐周腹痛，伴有消瘦、食欲欠佳；或有喜欢吃土块、炉渣等不良习惯，则应高度怀疑蛔虫症。

The the probabilistic forecasting method of the error between the sample mean and expectation value of the random variable utilizing the central limit theory was researched, then the mathematical formula for the relation between sampling size and variance coefficient of loss of load probability was analyzed. Furthermore, the formulas for the relation between confidence intervals of variance coefficient and sampling size are deduced.

基于中心极限定理深入研究随机变量的样本均值与期望值之间误差的概率预测方法，在此基础上分析失负荷概率(loss of load probability，LOLP)指标的方差系数和样本容量之间的关系表达式，导出方差系数给定时的样本容量置信区间公式及样本容量给定时的方差系数置信区间公式。

In order to maintain process safety and product quality the EPS 2000 crimp machine is subject to certain lubrication intervals.

Normally, time measure is including time discrimination and time to digital converter.

本文的第二章介绍了前沿定时、过零定时、恒比定时和ARC定时的特点。

The advantage of leading end discriminator is its simple structure, easy to realized and integrated.

恒比定时虽然能够消除幅度对定时的影响，但其结构相对比较复杂。

All patients were divided into two groups: the early period group and the late period group(from January 1997 to January 2004) and comparison was taken between two groups. The preoperative redox tolerance index, intraoperative hepatopetal blood occlusion of half liver, and postoperative arterial ketone body ratio were investigated and evaluated.

将病例分为前期组（前7年）和后期组（后7年）进行比较，同时对术前磷酸化耐受指数测定、术中半肝血流阻断及术后连续定时的动脉血酮体比率测定进行分析，并比较其价值。

Yes, I think I have an idea, so you and Dad can spend more scheduled time together .

对，我想我有个主意了，这样能让爸爸和你更定时的在一起。

The paper will show that, if appropriate time information are added into the signals over the Loran-C data channel (studied in the first part of the paper) or in which the current multi-chains signals can be skillfully dealt with(studied in the second part of the paper), the independence of Loran-C for precision timing can be perfected, as well as the precision of timing signals and the automatization level of UTC synchronization can be improved, thereby the Loran-C can be acceptant and employed widely.

本文通过研究认为，在罗兰C信道上增加合适的时间信息或利用多链罗兰C信息，能够完善罗兰C高精度授时的自主性，提高定时信号的精确度和用户定时的自动化水平，从而提升该系统的可利用度和可接受程度。作者所做工作及主要成果如下
