peak cross section 中文意思是什麼
peak cross section
解釋
最大截面-
The coupled equation method ( cem ) has been improved to calculate 4s subshell of mnl by adding 3d ~ ( 5 ) ( ( 4 ) ~ x ) 4s ( ( 5 ) ~ x ) channels, which were verified to play a key role to the magnitude of resonance structure due to the interaction between 4s kp transition and 3p 3d excitation. our calculation shows higher symmetry and a solo peak near 51. 7ev, which is in better agreement with experimental data than garvin ' s calculation. except 3p 3d giant resonance, there are obvious 3p nd ( n > 4 ) rydberg resonances with width in the total cross section of mnl
在研究錳原子4s殼層的共振結構時，我們首次在耦合方程方法中加入了3d ~ 5 （ ~ 4x ） 4s （ ~ 5x ）通道與大共振之間的相互作用，發現這類通道對於4s殼層的共振結構具有較大的貢獻，從而改善了在耦合方程方法中只考慮基態3d ~ 5 （ ~ 6s ） 4s （ ~ （ 7 ， 5 ） s ）的缺陷，為精確計算其他過渡金屬原子外殼層的共振結構做了很好的鋪墊。 -
The comparison between the experimental data with numerical simulation show that the model have a higher precision in the lateral scouring and sedimentation deformation, time interval quantity of deposition, and output sediment concentration process during sand peak at various cross section and is applied fairly good to practical engineering
青銅峽水庫的實測資料對模型驗證結果表明：模型在水庫不同斷面橫向沖淤變形、時段淤積量、沙峰期出庫含沙量過程都具有較高的精度，能較好地運用於工程實際。 -
The existence of the asymmetrical residual transverse circulation flows in pair is discovered in the residual vorticity field along the passage and sandbank cross section. the transverse residual circulation flow is favorable to sediment ' s moving to the peak of sandbank and the development and maintenance of sandbank
首次發現，在潮漲潮落過程中，深槽中及沙脊兩側均存在一組方向相反、不對稱余渦度場（余環流場） ，橫向余環流的存在將有利於沙脊兩側的泥沙均向沙脊頂運動和堆積，是潮流沙脊的形成和維持重要動力因素。 -
The results indicate that the peak intensity of transmission beam is limited, and the cross - section intensity distribution is approximately flat - topped super gaussian, which shows the optical limiting effect of sbs
結果表明，透射光束截面光強呈現出近似平頂的超高斯分佈，光強峰值被限制，顯示出受激布里淵散射的空間光限幅效應。
