小心地将天线与电缆匹配,以确保低定波比率(SWR)。
The antenna and cable must be carefully matched to ensure a low Standing Wave Ratio (SWR).
当传感器发现粉尘浓度达到了临界水平,就有一定的电荷促使该材料发出除尘波越过其表面。
Sensors detect when dust concentrations reach a critical level and then an electric charge energises the material sending a dust-repelling wave across its surface.
大卫就打发人去见扫罗的儿子伊施波设,说,你要将我的妻米甲归还我。她是我从前用一百非利士人的阳皮所聘定的。
And David sent messengers to Ishbosheth Saul's son, saying, Deliver me my wife Michal, which I espoused to me for an hundred foreskins of the Philistines.
Our friend Schr?dinger told us that if you solve for the wave function, this is what the probability densities look like.
我们的朋友薛定谔告诉我们,如果你用波函数来解决,你就会知道这些概率密度看上去的样子。
We looked at the wave functions, we know the other part of solving the Schrodinger equation is to solve for the binding energy of electrons to the nucleus, so let's take a look at those.
我们看过波函数,我们知道解,薛定谔方程的其他部分,就是解对于原子核的电子结合能,所以我们来看一看。
And the thing about what Schrodinger did was all he imposed on a system was the electron behaves as a wave and is bound.
薛定谔所做的,是建立在一个系统之上,电子是像波一样运动的并且是有界限的。
