1·Coordinates of a normal probability paper are calculated with a approximate formula of normal distribution integral curve and drawn on screen.

采用正态分布积分曲线的近似公式计算概率格纸的坐标，并在屏幕绘图。

2·The granularity distribution and average diameter of particles of red phosphorus smoke were tested and the integral curve of typical sample were given.

测试了红磷烟幕的粒度分布及平均直径，给出了典型样品的累积曲线。

3·In the line integral in the plane, you had two variables that you reduced to one by figuring out what the curve was.

在平面上的线积分中，有两个变量，可以通过了解曲线的形成规律，从而去掉一个变量。

4·How do I compute the line integral along the curve that goes all around here?

应该怎样沿着围绕这个区域的曲线，做线积分呢？

5·If we have a closed curve then the line integral for work is just zero.

如果给定一条封闭曲线，那么求所做功的线积分为零。

6·And so I want to compute for the line integral along that curve.

那我想计算那条曲线上的线积分。

7·And, I still want to compute the line integral along a closed curve.

但仍然想要沿着封闭曲线的线积分计算。

8·If it is a closed curve, we should be able to replace it by a double integral.

如果是一条闭曲线，也可以用二重积分来代替的。

9·OK, so if I give you a curve that's not closed, and I tell you, well, compute the line integral, then you have to do it by hand.

如果给你们一条非封闭曲线，然后让你们计算线积分，你们必须动手一点点来计算。

10·If you cannot parameterize the curve then it is really, really hard to evaluate the line integral.

如果无法对曲线参数化，那么就很难计算线积分了。
