cut-off energy

基本解釋

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(jìn)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(yīng)計(jì)算中的截?cái)嗄芰?、通量?jì)數(shù)方式、數(shù)據(jù)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(yīng)用分子動力學(xué)模擬方法，討論了NVE系綜中不同初始晶格類型對模擬系統(tǒng)平衡溫度和截?cái)喟朕煂δM系統(tǒng)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(diǎn)，實(shí)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(diǎn)，這時(shí)sigma2p軌道,比π2p軌道能量更低。
