查询词典 magnitude

With analysis on the control model, an improved automatic tuning method for arc-suppression coil is proposed, that is: adopting voltage feed forward control to restrain interfere of 50Hz displacement voltage, which can improve the characteristic of the injected signal significantly, make the injected signal without reference to unbalanced network and neutral displaced system. Another innovation is detecting the magnitude of neutral point signal-frequency voltage to judge the resonant state, which improves the sensitivity and accuracy of resonant judgement effectively.

基于对控制模型的分析，提出了一种新的注入变频信号的消弧线圈自动调谐方法：通过电压前馈校正控制的引入，有效抑制了50Hz工频电压对注入信号的干扰，使得注入信号不受电网不对称及中性点位移电压的影响；提出以中性点注入信号电压幅值最大做为新的谐振判据，有效提高了谐振状态判断的灵敏度和准确度。

We also simulate the environment of photon experiment, and calculate the effect by use of fourfold symmetry torsion pendulum, we find that the double frequency effect caused by gravitational gradient is reduced a magnitude when we buildup the symmetry of measurement system.

我们还对二重对称扭秤的光子实验数据进行了分析，结果发现二倍频的效应为10~(-12)Nm 的量级，通过计算分析我们发现扭秤周围环境的不对称所引入的引力梯度效应是不容忽视的，因此针对喻家山人防山洞的具体情况，我们对光子实验的实际环境进行了模拟计算，理论分析结果表明对于二重对称的扭秤而言，环境不对称的影响引起的力矩效应为5.4940×10~(-10) Nm，对于四重对称的扭秤来说，效应为1.8668×10~(-11)Nm，可以看到随着扭秤对称性的增加，引力梯度的效应减小了一个数量级。

The results show that the movements of tongue during swallowing are related to the dentofacial morphology especially in the motion magnitude of the early final phase, while only few correlations are found when analyzing the duration and speed of swallowing.

结果显示：舌头吞咽运动与齿颜面形态间是有相关的，尤其以早期终止期的运动振幅和齿颜面形态的相关性最为显著，而运动持续时间及速度与齿颜面形态间较无相关。

It is also found the rest position of tongue is highly positive related to the magnitude of phase Ⅱa and phase Ⅲa. It demonstrated that anterior teeth retraction would not affect tongue movement during swallowing.

结果显示，在矫正治疗完成前牙后退之后，舌头吞咽各分期的持续时间与振幅皆没有改变；因此可证明，舌头本身对矫正治疗后牙弓型态及齿列空间的变化，具有相当程度的适应能力。

The computer-aided B+M-mode ultrasonography was used to assess their tongue movements. Duration, magnitude and speed of tongue movements in different swallowing phase were measured from 112 healthy adult volunteers and compared with their dentofacial morphology using a simple correlation analysis.

选取112名健康的成年志愿者为受测对象（男性74位，女性38位，平均年龄为22岁），以电脑辅助B模式结合M模式口腔超音波防震扫描技术评估吞咽时舌头的运动情形，计算舌头在不同吞咽分期的运动持续时间、运动振幅以及速度，并以简单相关分析法求得与齿颜面形态的相关性。

The cephalometric radiography and ultrasound image of swallowing were recorded just before and after anterior teeth retraction. All the changes and correlation between the variable of anterior teeth and the variable of tongue movement during swallowing were all discussed. The result showed that there was no significant change on duration and magnitude during swallowing after anterior retraction.

以13位符合条件的志愿者为受测对象，分别在前牙退后之前后各取一次测颅X光片及超音波吞咽之影像资料；而后以测颅X光片描绘取得前牙距离、角度的改变比率，另以电脑辅助分析超音波吞咽影像，得到舌头吞咽各分期的时间振幅之改变比率，再进行统计分析。

看看这枚列宁勋章，这是至高无上的荣誉，上面写着&社会主义英雄&，只为最纯洁的工人阶级而设，以表彰我对社会所作的巨大贡献。

This study shows that there is a liner relationship among the earthquake magnitude, epicentral distance and abnormal signal amplitude of the geoelectric field recorded at Wenxian station. For the signals with bandwidth of 0.003-30 Hz, the duration time of the anomaly is related to the lead time and the azimuth of epicental location.

研究表明，对于文县地电场观测点而言，震级、震中距、异常电信号幅度之间存在着线性关系；对带宽为0.003-30 Hz的异常信号而言，震前异常的时间长短与异常开始至发震时刻的时间长短存在着密切关系，且与震中方位有关。
