查询词典 approximation methods in physics

A projection method is used to smooth out start and end points of the ruling line sets.

In early 3rd century, the ancient Greek women had to body curve and the pursuit of the original "invented", the "model body underwear model body underwear" using the approximation method of modern three-dimensional cutting, and in the waist with metal waist clip plastic waist, then, in this kind of dress of women in society status for the priests, the performers and palace ladies - this is the earliest human research into the "model body".

早在公元三世纪之初，古希腊的女性便有了对身体曲线的追求，并发明了原始的"塑身内衣"，这种"塑身内衣"采用了近似现代立体裁剪的方法，并在腰部用金属腰夹塑腰，当时，穿着这类服装的女性均为处于上流社会地位的祭司、表演者和宫中女士--这是可以考证到的人类最早的"塑体内衣"。
