dihybrid

On the base of the relativity and the data self - sealing characteristics of circular division measurement , an arbitrary measurement system on circular division and dihedral is built , and the processing method of the dynamic data zero average and the balancing based on self - sealing nature reference are also built 在圓分度測量的相對性和數據自封閉特征的基礎上,建立了基于圓分度和二面角測量的任意角測量系統,和基于自封閉自然基準的動態誤差數據零均值處理和平差處理方法。

The formed ca - h radicals lead to the variations of the dihedral angles and . thus verified our own hypothesis . as for the calculation of small molecule ' s c - h bde , density functional theory ( dft ) b3lyp is employed 量子化學計算表明,多肽鏈的ca - h的解離焓( bde )較小,易抽氫,且抽氫前后多肽鏈構象發生了很大的變化,這可以從構象角、的變化看出,從而從理論上驗證了我們的觀點。

In the secondary structure of peptide , dihedral angles and are the essential factors of c - h bde . each pair of ( , ) has unique bde value which varies with the different combination of and 在多肽鏈的二級結構中,二面角中和w是影響c hbde的主要因素,每一對( p , w )對應一個bde值, bde的數值隨中與w的變化而變化。

In the paper , we discuss the equation about angle bisector of intersecting line in the analytic geometry and the equation about the bisection planes of dihedral angles in analytic geometry of three dimensions 摘要主要討論了平面解析幾何中和空間解析幾何兩相交直線夾角平分線方程及空間直角坐標系下兩相交平面的二面角的角平分面方程。

Joined - wing configuration features diamond - shapes in both the plan and front views . the front wing is aft swept with positive - dihedral angle and the rear wing is forward swept with negative dihedral angle 聯結翼飛機是指帶上反角的后掠前翼和帶下反角的前掠后翼聯結成菱形框架結構的飛機。

A high - precise arbitrary dihedral and circular division measurement system is exploited at the first time ; the measuring and system controlling software based on ms windows are also exploited 首次研制成功了高精度任意二面角與圓分度測量系統,并編制了基于mswindows的測量和系統控制軟件。

Of a dihedral 二面角的面

The pucara has a low wing with no taper or dihedral on the broad center section “普卡拉”的低單翼寬大平直,沒有后掠角。
