你好： 回答你的問題： 第1題： 有種竹子一天長250mm，假設每個細胞是10/xm長。 1) 長一個細胞的高度要多久? 2) 一週可以長幾個細胞高度? Ans. 10/xm長，認定為筆誤，修正為10mm長。 1) 1天*10mm/250mm=1/25天 2) 7天*250mm/10mm=175個細胞高度 第2題： 使一個電子從6V電池的...
一二維穩定流場,其速度分量Vx=y(1+3t),Vy=-x,當t=0時流線經過(1,1),請求出流線與徑線方程式. 計算如下: t=0時(穩定流場)=>Vx=y,Vy=-x 設流線方程式y=f(x),依流線定義其切線斜率與速度方向一致 =>dy/dx=Vy/Vx=-x/y =>ydy=-xdx =>∫ydy=-∫xdx...
