Based on 6d rigid body trajectory equation, the spin-number formula of the projectile was deduced, by which the spin-number can be calculated.

基于旋转稳定弹丸的6d刚体弹道方程，导出了弹丸转圈数公式，可对弹丸圈数进行准确计算。

So by parallel we mean - they're either both spin up remember that's our spin quantum number, that fourth quantum number.

所以我们意味着，它们都是自旋向上，记住我们的自旋量子数，是第四个量子数。

And this spin magnetic quantum number we abbreviate as m sub s, so that's to differentiate from m sub l.

这个自旋磁量子数我们把它简写成m下标s，以和m小标l有所区分。

Having been absent with a broken finger during the Aussies' 6-1 trouncing of England in the recent one-day series, Ponting showed no ill effects, keeping his team on course for victory while others perished to Chawla's leg-spin and India's number one spinner Harbhajan Singh (3-15).

The program generated huge excitement, but it was a commercial failure, Five years later, Wurman tried again, and since then it's been held annually in California, with a growing number of spin-off events in other locations.
