Then again we turn to chemistry, and we figured out what this generic molecule is -- that was the pink ovals on my last slide, this is it.

我们又使用化学方法搞清了这个通用分子的构造--通用分子就是我上一张幻灯的粉红色椭圆形。

The moving points on the geometric locus are observed to study the properties of ovals.

为了考察卵形线的性态,对动点的轨迹曲线进行了研究.

He had just come up with a brilliant algorithm that could draw circles and ovals onscreen quickly.

他刚刚想出了一个绝妙的算法，可以在屏幕上快速画出和椭圆。

The retracting band of the magnetic field drags them down to the aurora ovals, which are the locations of the northern and southern lights.

往回缩的磁场将这些粒子拉进极光椭圆区，即发生北极光和南极光的位置。
