If you have a spinning gyroscope and you try to rotate its spin axis, the gyroscope will instead try to rotate about an axis at right angles to your force axis; this is precession.

如果您有纺纱陀螺仪和您尝试旋转，其旋转轴，陀螺反而会尝试旋转约一轴成直角，以您的力量轴；这是岁差。

In practical experiment on a ceramic cylinder gyroscope, it shows that the resonant frequency is quite approximate to the simulated one. A good linear relation of the sense voltage to rotation speed is obtained, which indicates the piezoelectric ceramic cylinder gyroscope is good at the measurement for low and medium rotation speed.

在圆柱型陀螺仪之实验过程中，显示驱动与感测之共振频率几乎为一致；而在旋转实验中得到转速与感测电压拥有良好的线性关系，亦指出该陀螺仪在中低转速下拥有较佳之线性关系。

This measurement system not only can measure superelevation of railway, but also curvature of curves, from which the unbalanced centrifugal acceleration can be computed to provide the instruction information for tilting control.

基于单轴陀螺平台的摆式列车线路信息检测系统，利用安装在头车车体地板上的单轴陀螺平台和车体与悬挂系统之间的两个位移传感器建立测量的水平基准线，不仅可测量出列车通过曲线时线路的超高值，而且可测量出曲线曲率值。

In orderto improve the complex subspace iteration method for solving undamped gyroscopiceigenvalue problems, we apply the special properties of undamped gyroscopiceigenvalues to it, so we propose double inverse iteration method and double subspaceiteration method.

为了利用无阻尼陀螺特征值的特殊性质，我们进一步讨论了复子空间迭代法在无阻尼陀螺特征值问题中的应用，并给出了双逆迭代算法和双子空间迭代算法。

A frame is set up in this paper that the unit vector of the star is taken as Z axis of the frame, and all the constant gyro drifts of inertial navigation system are projected on to the frame .

如果建立一个以星体方向为Z轴的坐标系，并将陀螺漂移投影到该坐标系，文中将证明绕该坐标系Z轴方向的陀螺漂移是不可观测的，并分析由此引起的导弹落点误差。

FOG is one kind of laser gyroscopes. IT is based on the interferential theory of Sagnac. And its lamp-house is used with laser. A photic loop is made by fiber. There are clockwise and withershins sheaveses of lights transfer in the circle. With the turn of the circle ,the two lights introduce phasic difference ,so the angle velocity is measured.

光纤陀螺仪是激光陀螺的一种，它采用的是Sagnac干涉原理，以激光作为光源，用光纤构成环形光路并检测出由正反时针沿光纤传输的两束光，随光纤环转动而产生的两路激光束之间的相位差，由此计算出旋转的角速度。

At last, the Z-axis micromachined gyroscope was fabricated in a bulk micromachining process, the difference between design and fabrication has been analyzed.

最后，实际进行Z轴微机械陀螺的流片加工，分析了检测的结果，比较验证了陀螺集成设计方法。

As mentioned above, this dissertation can be divided into two parts. One is devoted to study the high resolution ro-vibrational spectra of some asymmetry top molecules, such as D〓O and DOCl. Another is about studying anharmonic force field and vibrational intensities of some symmetry top molecules by quantum chemistry method, such as SiHCl〓 and AsH〓.

因此本论文的工作以此为脉络分为两个部分，第一部分以D〓O和DOCl分子为体系，研究非对称陀螺分子的高分辨振转光谱；第二部分以对称陀螺SiHCl〓和AsH〓分子为体系，用量子化学计算的方法研究了小分子的非谐性力场和振动光谱强度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
