particle cross-section 中文意思是什麼
particle cross-section
解釋
粒子截面-
That is well taken into account when calculating particle production, but not when cal - culating cross section
無論是處理幾率計算還是粒子產生，無論是第一個pomeron還是多個pomeron都如此。 -
So cross section and particle production are not calculated consistently. and it is difficult for gri5ov - regge theory to include hard process. the parton 6ased gri6ov - regge theory provide a solution : elementary scatterings happen in parajlel, described phenomenologically as pomeron exchanges
因此，在nexus中pomeron的色弦形成方式就與其它模型很不相同；即使只有一個pomeron交換，色弦的端點也是海夸克和反夸克，而不是價夸克。 -
Secondly, the mathematical radiation extinction model of nonspherical particle is developed based on t - matrix method, and a computer program is designed to calculate the extinction cross section, scattering cross section, absorption cross section and scattering phase function of fixed or randomly oriented axially symmetric particle
然後根據t矩陣方法，採用回轉體微粒消光特性的計算模型編制出的相應程序，對固定取向和隨機取向的非球形回轉體微粒的消光截面、散射截面、吸收截面及散射相函數進行了計算。 -
Cross section morphology analysis showed that the fracture appearance of tungsten carbide particle reinforced steel matrix composites was a mixture of quasi - cleavage fracture and toughness fracture. the fracture appearance of tungsten carbide particle always displayed as quasi - cleavage fracture, while the cross section morphology of steel matrix transformed with the heat treatment techniques
斷口形貌分析顯示， wc鋼復合材料的斷口形貌呈韌-脆復合斷口特徵，硬脆的wc顆粒常發生脆性解理斷裂，而韌性較高的鋼基體的斷口形貌則因熱處理工藝而異。 -
Thirdly, the cluster - cluster aggregation model is used to study the possible structure of aggregated smokescreen particle. we also develop the mathematical radiation extinction model of aggregated particle based on t - matrix method. associated with monte carlo method, another computer program is designed to simulate the extinction cross section and scattering cross section of actually aggregated particle
本文還將「凝聚體?凝聚體」凝聚模型應用於煙幕凝聚現象研究，模擬出了煙幕凝聚粒子的可能結構，並且根據t矩陣方法發展了凝聚粒子消光特性的計算方法，結合montecarlo方法，編寫了能夠模擬實際煙幕凝聚粒子消光截面、散射截面的計算程序。 -
The calculated double differential cross section of the new model is compared with experimental data and previous scdw calculations with single particle model. the calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi - elastic scattering ( qes ) angle. the agreement with experimental data is much improved
新模型的雙微分截面計算結果與實驗值以及以前採用單粒子殼層模型時的計算結果進行了比較，表明cdfm模型的引入對scdw模型的計算結果有較大的改進，使其在大角度和極小角度區域有所增大，在準彈性散射角附近有所減小，從而能更好地與實驗值相符合。 -
It reveals the influence of different cross - section, gas velocity, the height of bed materials, particle mean sizes and solid circulation rate on the particle movement
獲得了不同測試截面的流場固粒速度，以及操作氣速、床料高度和床料平均粒徑等對固粒速度的影響規律。
