泡沫混凝土耗能层能够明显减小结构的动力响应,可以用来构筑较理想的结构消波吸能型式。
The dynamic response of tunnels can largely be reduced by the foamed concrete backfill layers, which can be used to construct a sort of ideal energy absorption support structure.
液压系统的冲击、振动和噪声是系统中常见的弊端,采用消波器是减小系统冲击噪声的有效方法。
Impulse, vibration and noise are ordinary troubles in hydraulic system, which is an available measure to reduce impulse noise while wave attenuator is used in the system.
文章基于小波变换的消噪原理,结合待测信号的特点,创造性地提出一种适用于捷联寻北仪的小波消噪法。
Base on wavelet denoising theory as well as the characteristic of the signal, a wavelet denoising method applied to Strapdown north seeking system was proposed.
So we can actually constructively and destructively combine these waves, these atomic orbitals to make a hybrid.
我们可以相长,和相消叠加这些波,这些原子轨道可以杂化。
But first, I just want to remind you when we're talking about molecular orbital theory, this is treating electrons as waves, so what we're actually able to do is either constructively or destructively combine atomic orbitals to form molecular orbitals.
但首先,我要提醒你们,当我们讨论,分子轨道理论的时候,我们把电子看作是一种波,所以我们可以相长叠加,或者相消叠加这些原子轨道来组成分子轨道。
sb So in this case we would have 1 s a and 1 s b, and instead we would subtract one from the other, and what we would see is that instead of having additional, more wave function in the middle here, we've actually cancelled out the wave function and we end up with a node.
在这种情况下我们有1sa和,两者相减,我们可以看到不是在,中间有了额外更多的波函数,而是我们消掉了,波函数得到一个节点。
