hodometer

On the other hand , it is indicated that the velocity field consists of a depth - independent inertial oscillation and a time - mean shear flow , which can be obtained by subtracting the inertial oscillations time mean in one inertial period . the hodograph of the velocity vector of time - mean flow at the different depths consists of a ekman spiral , and the surface velocity is 30 . 3 ? to the right of the wind 一維模式的流場結果表明,混合層中的流場是由慣性波動與時間平均流兩部分疊加而成,且通過時間平均消去慣性波動后得到平均流,其不同深度的流速矢量構成一ekman螺旋,表層流速矢量相對風向右偏了30 . 3 ’ 。

The construction of pythagorean hodograph quintic spirals is introduced . its use for the various transitions encountered in highway design is analyzed . practical examples of highway design , namely , straight line to circle , circle to circle with c transition , using quintic ph spirals are illustrated 介紹了五次ph螺線的構造,并將其應用于高速公路過渡設計中,展示了應用五次ph螺線進行直線到圓的過渡,圓到圓的c形過渡的實例。

The blending surface is itself a generalized canal surface , the spine curve of which is a ph pythagorean - hodograph curve 曲面拼接問題是計算機輔助幾何設計cagd計算機圖形學cg等領域中的一個重要問題。

Peak updraft strength is slightly enhanced with hodograph curvature , 29 . 0 m / s in b versus 26 . 1 in c 山頂上升氣流強度隨速矢端跡曲率加大而稍有加強,在(圖上) b點是每秒29米, c點是每秒26 . 1米。

A transformation that is most useful in the application of the hodograph method is the inversion transformation . 在速端曲線法的應用中,一種最有用的變換是反演變換。

Points in the physical plane are mapped onto corresponding points in the hodograph plane . 物理平面上的點被映射到速端曲線平面上的對應點。
