查询词典 zero

According to Lyapunov stability analysis, it is proved that the proposed method can guarantee both synchronization and position errors converge to zero and the system is asymptotically stable.

基于李亚普诺夫稳定性理论证明了所提出的控制策略能够使同步误差和位置误差均收敛到0，并且只保证了系统的渐近稳定性。

The result is a double zero at infinity.

结果是双重零在无限。

The results can tend toward infinity at different rates or toward zero, even though the initial points are very close together.

结果以不同速率趋向无限大或趋向零，即使初试点是非常接近。

Moreover, a example is also included to illustrate the main result obtained when f has suplinear growth at zero and at infinity in z.

另外，当f在原点处和无穷远处关于z超线性增长的情况下举例验证了所得到的主要结论。

The reason is that soonest at the next current zero-crossing the firing pulse of thyristors can be reset.

通常的短路故障电流会大大高于这个倍数，而软启动器的晶闸管本身是没有短路分断能力的。

From the lumped equivalent circuit model, the phase shift/attenuation and impedance characteristics of the novel structure are first analysed based on the Bloch theory, which shows the novel structure has properties analogous to those of a bandpass filter: the attenuation constant keeps zero with a continuous and smooth characteristic impedance distribution within the passband and the bandwidth may be arbitrarily specified; characteristic impedance is purely imaginary with the inhibition of the electromagetic wave propagation outside the passband.

首先从一般的等效电路模型出发，根据Bloch周期性理论对该结构的相移、衰减和阻抗特性进行了分析，结果表明该新结构具有类似带通滤波器的特性：通带内衰减常数为零，特性阻抗为实数并随频率连续平滑分布，具有可任意指定的阻抗匹配带宽；带外特性阻抗为纯虚数，电磁波传播受到抑制。

Finally,a semi-fragile zero watermarking algorithm is designed based on the high frequency property of audio signal.

然后，结合离散小波变换的多分辨率分析特性、离散余弦变换的能量压缩特性以及高阶累积量的高斯噪声抑制特性，提出了一种音频零水印算法。

MAICO designed and produced the first hearing test instrument with a "zero reference level", coining the term "audiometer".

MAICO会秉承这一宗旨，不断提高我们的产品占有率，并不断的改进产品的设计和性能。

The zero-position is the position of the Z-axis, with which each measuring objective of the autocollimator

If you want to modify the clock, pressure Settings button to display window, input zero - 23:59 at the score (e.g., at about 3:30 p.m., second automatic reset input 1530, set the clock in 24 hours, and then press enter) system clock.

若要修改时钟值，压设置键显示窗口在闪烁，输入0-23点59分的时分值（如下午3点30分输入1530，秒自动清零，设置时钟时按24小时制输入），然后压时钟键即可。

"The operators will suffer a temporary decrease in the number of consumers and short message services as people may not like having to provide their ID cards for a phone number," Xu Junqi, vice-dean with the Policy-Making Institute of the Telecommunications Research Centre under MII, said yesterday.

信息产业部下属的通信决策研究院副主任徐俊其昨天说：&实行手机实名制后，人们可能不太情愿用身份证注册手机号，所以通信运营商会暂时面临用户减少和短信用户减少的问题。&

I don't believe in make-believe!

我不相信这些虚构的故事。
