When processing, if the stable time is obtained, the drill can be moved on Z-axis direction, and can be cut into printed circuit board.
在加工时,一旦经过获得的稳定时间后,钻便在Z轴方向上运动以切入印制线路板。
So z equals 7 -- this is the cut-off where, in fact, the sigma orbital is going to be higher in energy than the pi 2 p orbitals.
所以z等于7-这是分界点,实际上,sigma轨道能量,要比π2p轨道高。
z And what you need to remember is if the z 8 is equal to eight or greater, such as oxygen being the cut-off point, this sigma 2 p orbital is actually lower in energy than the pi 2 p orbitals, the molecular orbitals.
你们要记住如果,等于或者大于,就像O是分界点,这时sigma2p轨道,比π2p轨道能量更低。
