So, you know, if you find that the area is too easy, you can integrate any function other than ellipse, if you prefer.
你们都知道，要求这个面积是非常简单的，如果你们想的话，可以积分除了椭圆函数以外的任何函数。
Let's say that we want to find the area of an ellipse with semi-axes a and b. OK, so that means an ellipse is just like a squished circle.
现在需要计算一个以a，b为半轴的椭圆的面积,其实椭圆就是一个被压扁的圆。
So, we know that we want to integrate just the area element, let's say, dx dy over the origin inside the ellipse.
我们知道现在要积分面积元素，那就对dxdy积分。
Once you’ve blurred the ellipse, cut the top half away from the divider by using the Rectangular Marquee Tool and deleting the area beneath it so that you are left with half an ellipse.
然后使用矩形选框工具删掉分割线上半部分，这样就剩下了半个椭圆。
Moreover, there is still a large error area of probability ellipse, which makes the precise location cannot available.
而是存在一个不小的概率椭圆误差区域，因而无法精确确定被测目标的真实位置。
Instead of using point sampling, elliptical filtering USES an area (an ellipse) to perform an image lookup.
替代了点采样，椭圆形过滤使用一个椭圆形区域来执行图像检查。
Finally, the oil level is obtained by normalizing the area of the oil part and the oil-free part within the ellipse into the circle shape.
最后计算椭圆中有油与无油部分的面积，将面积归算至油枕端面圆形中得到最终的油位值。
In order to overcome this problem and narrow area, some scholars lead into the idea of restricted searching area, such as restrict to ellipse and restrict to rectangle.
为了克服这个问题，有的学者引入了限制搜索区域的思想，缩小搜索空间，比如椭圆限制、矩形限制等。
The ellipse arc may depress the acceleration of supersonic flow in inlet area, decrease the strength of inlet shock wave.
椭圆形的前缘可减弱超音气流在前缘进口区的加速程度，降低进口弓形波的强度；
Some geometric data of ellipse in hyperbolic space are considered, such as set inclusion, arc length, geodesic curvature, curvature, area and total curvature.
在双曲空间中，考察椭圆的包含关系，对弧长元素、测地曲率、曲率、面积及全曲率等几何量做出细致考察。
