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。 -
According to the population equilibrium equation and utilize the population poly - factor compounding projection, this paper expounds the basic population projection methods and steps in the exoteric regions so as to provide the concrete population forecast practice some instructions
本文依據人口平衡方程，運用人口分要素組合預測法，闡述了開放區域人口預測的基本方法和步驟，從而為具體的人口預測工作提供思路借鑒。 -
The relatively simple mass continuous equation is used to calculate vertical velocity, and use radial velocity projection relation of dual - doppler radar to retrieve the three - dimensional wind field
採用較簡單的質量連續方程求取垂直速度方案，利用兩部雷達的徑向速度投影關系反演大氣三維風場。 -
The results show that the auto - conversion of frozen drops and graupels ( cnfh, cngh ) are the main sources of the hailstones in the strong convective storm studied in the paper, but the contribution of frozen drops is greater than that of graupels. hailstones mainly depend on the processes of collecting supercooled water ( clch, clrh ) to grow. the relatively simple mass continuous equation was used to calculate vertical velocity, and use radial projection relation of dual - doppler radar to retrieve the case ' s three - dimensional wind field
同時模擬分析了冰雹形成的微物理過程，結果表明，本個例模擬雹雲中，冰雹粒子主要由凍滴和霰轉化（ cnfh ， cngh ）形成，但凍滴對冰雹形成的貢獻要比霰大得多，冰雹含水量中心的發展演變與凍滴含水量中心的發展演變相一致，冰雹主要是通過撞凍過冷水過程（ clch ， clrh ）而進一步長大的。 -
The regional spectral model component is a primitive equation model on a stereographic projection and uses sine - cosine series as horizontal basis functions. the regional component predicts deviations from the forecasting of the global morjel component
區域部分的預報偏差來自全球模式部分的預報，在區域范圍內，半隱式時間格式、時間濾波、初始化和水平擴散的應用都與偏差有關。 -
