水平井井眼轨道预测和控制问题的技术关键是准确计算各种造斜工具的造斜能力。

To exactly calculating the build rate of building motor assemblies and others is a key point of correct prediction and control for bit trajectory in horizontal drilling.

他立即运行中心的轨道预测软件，计算小行星离地最近距离，然后打电话警告切斯利一场即将发生的小行星撞地球。

He ran it through MPC's orbit-projection software, which can tell how close an asteroid will come to Earth, and phoned Chesley to alert him of an impending collision.

在我们的太阳系中，行星的轨道几乎是圆形的，这使得科学家们预测，其他恒星周围的行星也会位于圆形轨道上。

The nearly circular orbits of planets in our solar system led scientists to expect that planets around other stars would also reside in circular orbits.

All right, so we can now see a little bit of what the power of molecular orbital theory is in predicting what kind of bonds we're going to see in molecules, or whether or not we'll see this bonding occur at all.

好了，我们已经可以看到一点,分子轨道理论在预测分子中,所成的键或者分子，能不能成键方面的能力了。

This was something we could not predict using Lewis structures, but we can predict using MO theory that we have a radical species here.

这是我们从Lewis结构里不能预测的，但我们可以用分子轨道理论,预测自由基。

And there's actually a way that we can make predictions here, and what I'll tell you is molecular orbital theory predicts that h e 2 does not exist because it's not stabilized in terms of forming the molecule.

其实我们有一种办法可以做出预测，我要告诉你们的是分子轨道,理论预测He2不存在,因为它形成分子不稳定。
