normal line 【機械工程】法線。

normal mode

First calculation method : doing horizontal projection drawing on drawing piece , k value is introduced by area equation of projection drawing , k value is obtained by area equation , along outline of projection drawing to add k value , that is , outline shape of blank drawing , principle area - equal and shape similar are used . second calculation method : along outline of drawing piece horizontal projection drawing , to do normal line of penetration line for wantonly point of this point , to obtain high of drawing piece on this point normal line , point and point is to form outline shape of blank 計算方法之一為k值法:作拉深件水平投影圖,在該投影圖面積方程中引入k值,利用面積相等原理解方程,求得k值,沿水平投影外沿加上k值,即為毛坯圖的外廓形狀。計算方法之二為拉深線法:沿拉深件水平投影圖外廓,在任意點作該點切線的法線,在該法線上以該點拉深件的高度為量,在法線上取截點。

There is great change of negative current component when it happens the line - open fault . it is marked as the occurrence of the fault . and it can be concluded the phase characteristic of negative current in the line . in the transient course , there are plenty of harmonics in the fault line . through the transient analysis , it is drawed that the amplitude of each harmonic in fault phase is greater than other phases . harmonic current in fault line is far greater than other normal lines 發生斷線故障以后,線路中會出現負序電流的突變,可以作為故障啟動判斷的標志,并且通過分析得出了故障時負序基波電流的相位特點。在故障暫態過程中,故障電流中含有大量豐富的諧波成分,各次諧波在故障期間有突變,并且衰減很快。

There are some geometry characters about it , for example , it is simple in structure , and the normal lines along generatrix line are in one plane , so there are the extensive applying prospects hi mechanical transmission and surface processing 此類曲面結構單純,沿母線法線共面,并且有許多重要的幾何性質,在機械傳動和曲面加工中有著廣泛的應用前景。

Entity knowledge base provides computing models information , such as , life or not , fly or not and so on . besides , there are some geometry properties such as normal line , orientation and so on 實體知識庫提供實體的基本屬性信息,比如是否具有生命,是否會飛的屬性,另外還有一些幾何屬性,法線方向、朝向等。

Idea of differential plane is introduced in the calculation of orientation of normal line , and optimal orientation for electron gun is obtained . this work is helpful for guaranteeing welding quality 在法線姿態的計算中,引入微分平面的設計思想,獲得了焊接過程中的最佳姿態,保證了焊縫質量。

Since the lines in the address are separated by normal line separators the “ - n “ character , the code needs to replace these with xhtml - style line separators , 因為地址中的行用一般的行分隔符( “ n ”字符)分隔,代碼中需要用xhtml風格的行分隔符

The angle drawn at the point of incidence ( intersection of ) a reflected ray and the normal line perpendicular to the reflecting surface 中義光線在物體表面的投射點上反射出來的光線與物體表面垂直法線所夾的角度。

None of my normal lines work on her 我貫用的伎倆對她都無效

Characteristic of normal line of compact connected surfaces 緊致連通曲面的法線特征
