So, molecular orbital theory, on the other hand, is based on quantum mechanics.

另一方面分子轨道理论，是基于量子力学的。

So the product of Newtonian mechanics of predicting the future given the present, has got two parts, and one is called kinematics and the other is called dynamics.

所以牛顿力学,基于现状对未来的预测,包含两个部分,一部分被称为运动学,而另一部分被称为动力学

But they're not accurate all the time in predicting bonding within molecules, and the reason for this is because Lewis structures are not, in fact, based on quantum mechanics.

但它们在预测分子内,成键时不总是正确的，这是因为Lewis结构，实际上不是基于量子力学的。
