cut-off energy

基本解释

The problems on diagnostic to flare models, energetic particles propagation, and the low energy cut-off of the non-thermal electrons are discussed.
對耀斑的診斷，高能粒子的傳播，以及對非熱電子譜的低能截止等問題進行了討論。
With MCNP/4B code, the influence of cut-off energy, flux tallies, nuclear databases and perturbation on the reaction rates calculation with neutron-activation method are analysed.
用MCNP／4B程序，對核活化法反應計算中的截斷能量、通量計數方式、數據庫、閾探測器之間的擾動等因素的影響作了分析。
The effects of initial different crystal lattice of simulated system on balance temperature and cut-off radius on total balance energy were discussed in NVE ensemble by molecular dynamics simulation.
本文應用分子動力學模擬方法，討論了NVE系綜中不同初始晶格類型對模擬系統平衡溫度和截斷半逕對模擬系統平衡縂能的影響。

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等於7-這是分界點，實際上，sigma軌道能量,要比π2p軌道高。

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.
你們要記住如果,等於或者大於，就像O是分界點，這時sigma2p軌道,比π2p軌道能量更低。
