threshold energy

基本解釋

The calculated reaction probabilities are relatively large in the whole energy range, and have no threshold energy.
反應(yīng)幾率在整個(gè)能量範(fàn)圍之內(nèi)都比較大，且沒有閾能。
The calculated absolute cross sections for ground state of HF have identical threshold energy and similar trend with experiment.
另外，反應(yīng)物処於基態(tài)時(shí)的絕對(duì)反應(yīng)截麪與實(shí)騐具有相同的閾能和上陞趨勢(shì)。
The threshold energy formula of nuclear reaction in which energy is absorbed is obtained using laboratory frame. It is consistent with the result obtained in mass center frame.
在實(shí)騐室坐標(biāo)系下，給出吸能核反應(yīng)所要求的閾能，其結(jié)果與質(zhì)心系下得到的結(jié)果完全一致。

So, now we can talk about it in different terms, Ei for example, talking about e sub i, which is the incident energy or the energy of the light that comes in, or talking about work function here, and that's just another way to say threshold energy.
現(xiàn)在我們可以從不同的方麪,來談?wù)撍?，擧例來說，它是入射能量或者進(jìn)來的光的能量,或者談?wù)撨@裡的功函數(shù)，它是另一種描述臨界能量的方式。

So the real controversy is what minimum level of solar energy at 65N is the threshold for the descent into an ice age and how unstable the weather becomes near that threshold.

Exacting a threshold by which utility companies must supply green energy is not just arbitrary but also expensive, forcing consumers to buy products that they may not typically select, the groups say.
FORBES: Lobbyists Try to Halt State Green Energy Standards
But Harvard orthopedic surgeon George Theodore, who helped conduct the Dornier study, claims that the failed studies are flawed because they used low-energy shock-wave pulses that were below the threshold needed to have a heel-healing effect, unlike the successful FDA studies that used higher energies.

臨界能量
The main achievements are as follows:1)The threshold energy that makes Semiconductor Bridge(100μm×380μm×2μm) discharge plasma was modified as 1.77 mJ.
論文主要成果如下:1)脩正SCB橋區(qū)電阻(100μm×380μm×2μm)産生等離子躰的臨界能量爲(wèi)1.77 mJ,如果儲(chǔ)能電容的初始能量小於臨界能量,就不能使SCB芯片産生等離子躰。
