查询词典 alpha rays

These studies reveal that the degradation and the enthalpy change of composites would increase with the doping dose of alpha iron nanoparticles increasing, but the temperature of composites degradation would reduce.

研究结果表明：增加纳米α-Fe的掺杂量能提高PS的降解率，降低降解温度，增大热分解的焓变。

Our research aims to research and design an spectrometer-identificator to simultaneously or separately detect the fluxes and spectra of protons, alpha particles, oxygen and iron ions distributed in space.

为了满足当前空间环境的探测需要，需要研制一台全频道的空间带电粒子探测谱仪，该谱仪能够同时测量空间质子、α粒子和重离子的能谱和通量分布。

A multi-functional spectrometer-identificator is developed to measure fluxes and spectra of protons, alpha particles, oxygen and iron ions in space.

这套空间带电粒子谱探测系统主要有金硅面垒探测器、CsI闪烁体和改进的快响应电子学系统构成，包括ΔE-E望远镜系统和数据的获取及处理系统。

The detectors were irradiated with a mono-energetic beam of charged particles, which are protons, alpha particles, oxygen and iron ions.

粒子的能量刻度采用的是1／3档，在ΔE〓探测器中每道能量H〓=0.107MeV／道，在ΔE〓探测器中每道能量H〓=0.123MeV／道。

The hot alpha particle power absorption is important only when the damping is weak.

计算还得到，只有在弱阻尼的情况下，α粒子吸收的功率才是重要的。

Thus the alpha particle is an exceptionally stable nuclear structure.

由此可见，α粒子是一种特别稳定的核结构。

The SucceSs of Rutherford's theory of alpha particle scattering giveshim the distinction of having discovered the atomic nucleus.

由于卢瑟福成功地提出了Ot粒子散射理论，人们将发现原子核的荣誉归功于他。

The alpha particle radiation emitted by DU travels less than an inch and can be stopped by cloth or even tissue paper.

阿尔法粒子辐射所发出的旅行杜少於一英寸，可也阻挡不住的布，甚至卫生纸。

Its isotopes, all radioactive, are highly toxic radiological poisons because they give off alpha particle s and are specifically absorbed by bone marrow.

它的所有同位素都是放射性的，因其放出的α粒子易于被骨髓吸收而具有高度的放射性毒性。尽管具有潜在的致命性，它的毒性通常是被夸大了的。

Alpha particle s have two positive charges and a mass of four atomic mass units; they are identical to helium nuclei.

因为α粒子有两个正电荷，质量为4，射出后产生的子核的正核电荷和原子序数都比母核小两单位，质量小四单位。

We stopped by the old fashion ice cream parlor Manhattan Beach Creamery for some refreshment. The "No Shoes, No Shirt, No Problem" sign on the wall epitomizes the beach lifestyle.

我们去商店区的一家老式冰淇淋店坐坐，墙上挂著「没鞋，没上衣，没问题」的牌子完全捕捉了海滩生活的随性及风格。

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
