ellipsoid

基本解释

Using mismatched ellipsoid models in your data is not generally a major problem.
在数据中使用不匹配的椭圆体模型一般是主要问题。
So we place the scene node 50 units over the center of the ellipsoid with this parameter.
所以我们用这个参数把场景结点从椭球中央上移50个单位。
Unlike the ellipsoid model, using the correct projection is essential, and using data with mismatched projections often results in comedic errors, such as the layout error seen in Figure 3.
与椭圆体模型不同的是，使用正确的投影非常必要，使用不匹配的投影会造成让人笑话的错误，如图 3 中的布局错误。

s plus 1s gives you this oval ellipsoid which is the bonding, and here are the antibonding, and then these are the energy levels that I have been drawing for you.
s和1s上两个电子组成的键合电子成椭圆形,这是成键，这是反键电子，这些是刚刚已经画过的能级,我也给你们画了。

a geometric surface, symmetrical about the three coordinate axes, whose plane sections are ellipses or circles. Standard equation: x/a + y/b + z/c = 1, where a, b, c are the intercepts on the x-, y-, and z- axes

Based on the probabilistic model description and the multi-ellipsoid model description for different types of uncertainties,a reliability-based optimization model of structures combining stochastic and bounded uncertainties is mathematically formulated with constraints on mixed reliability indices defined in standard U-space.
