水流线

Boundary value problems in classical hydrodynamics are usually transformed from the physical plane to velocity plane by hodograph method.

在古典水动力学中，对於二维、稳态、不可压缩、无旋流场且不考虑其他外力影响之平面射流问题，常用速度矢端图法将其由物理平面转换至速度平面，再以复变函数法求得平面射流问题之自由流线参数方程式，但其求解过程甚为繁复。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
