寬束輻照 的英文怎麼說
中文拼音 [kuānshùfúzhào]
寬束輻照
英文
broad beam irradiation-
In the calculation, the energy deposited in aluminum by proton beams is first calculated by m - c simulation, then a 1 - d elastic - plastic fluid model is used to simulate the following thermal shock wave process as a result of thermal - mechanical effect by proton irradiation. the shape of proton is taken as a rectangle pulse with a width of 0. 1 microseconds, the energy flux o
對於3mm的鋁材料，入射粒子束為矩形脈沖（脈寬為0 . 1 s ）的情況下，計算得到了電子束、質子束輻照引起鋁材料斷裂的能注量閾值與入射電子束、質子束能量的關系曲線，該曲線存在最小值，分別對應6mev的質子束的34 . 7j cm ~ 2和0 . 35mev電子束的42 . 1j cm ~ 2 。In the hipib strengthening experiments, samples of high - speed steel ( w6mo5cr4v2 ) were irradiated by abstract hipib ( cn + = 30 %, h + = 70 %, ion energy 250 kev, ion current density 60 - 180a / cm2, pulse duration 80 - 100 ns ). microstructure investigation and properties characterization of the treated hss samples were carried out to investigate the effect of current density and pulse number of incident hipib on the surface modification treatment. the physical mechanism of the hipib - solid interaction was established based on the experiments
在hipib轟擊材料表面方面，本文選擇成分由c ~ （ n + ） （ 30 ）和h ~ + （ 70 ）組成、加速電壓為250kv 、脈沖寬度為80 100ns的hipib對高速鋼（ w6mo5cr4v2 ）進行表面輻照處理，研究離子束流密度和脈沖次數對高速鋼微觀結構和宏觀性能的影響，探討了hipib與材料表面相互作用的物理機制。Under the condition of the same total power, both large single beam and small multi - beam can enlarge the lateral area of the light propagation effectively, but the maximal light absorption rate increases for latter approach
在總功率相同的情況下，使用單束大功率寬光源與多束功率較小的小光斑光源均能明顯地增大光的側向傳播距離，但使用多束功率較小的小光斑光輻照時生物組織中的最大光吸收率增大。
