With sympathetic vibration demodulation of the vibration signal of the low-speed, high-load bearing which is realized by means of generalized harmonic wavelet transformation, the impact information of faulty hearing is extracted, which promises a new and effective method for the fault diagnosis of the bearing.

通过广义谐波小波变换实现低速重载轴承振动信号的共振解调，从而提取出故障轴承的低频冲击信息，为低速重载轴承的故障诊断提供了一种新的有效方法。

Because the portal frame is also used in the rig for bogie fatigue strength testing, in which the imposed load is harmonic, the modal analysis is necessary. The fundamental vibration mode shapes and corresponding frequencies are calculated to validating that the natural frequencies of the structure have enough difference comparing to the load frequency, so sympathetic vibration can be avoided.

由于龙门架还要在疲劳试验台中用来进行转向架的疲劳试验，因此对龙门架进行了模态分析，计算龙门架结构的固有频率和振型，确保龙门架的固有频率远离转向架疲劳试验的加载频率，避免在试验中发生共振。

Now if the pedal is depressed after the note is struck, there will be sympathetic vibration in octave and harmonic strings, but all the other strings will be almost totally quiet because the standing waves contain only pure harmonics.

钢琴不只选择性的让常态模式留在钢琴中，还会选择性的发出常态模式的音响。如果在弹下一个音之后再踩下延音踏板，此时就只有八度音及一些和弦音的弦会受到影响而震动，其它的弦几乎都不会受到影响而保持静止状态。

提出了调配融合算法、创造了"中国拼图"算法，高质量地应用于数字图象信息隐藏；此外，还研究了不同算法的综合技术，用于不同信息载体中的多媒体数据之间的信息隐藏，取得了成功的经验。

Similarly, reprises of earlier passages later in a piece not only have their melodies ornamented and varied, but also can move off on quite a different harmonic course, or with the accompaniment transformed, allowing the symmetry of ternary form to be offset by a more forward-moving dramatic shape.

同样的，在一个篇章后部对较早段落的重复不仅具有各自不同的加以修饰和改变的旋律，而且还使用不同的合音方式及伴奏配乐。这样一来，就用一种前移的生动形态弥补了三元形式对称的不足。
