另一些观点包括制造一种检测器来试验原子核的旋转动量能否被测量出，或者运用该技术来制造超灵敏的触角。
Other ideas include building a detector to see if the spin of an atomic nucleus can be measured, or using the technique as an ultrasensitive antenna.
只要我这样使力，旋转的角动量就是想要，水平的转动。
And as long as I torque it like this, that spin angular momentum wants to go around in the horizontal plane.
关于这个轴的,旋转动动量是多少？
What is the moment of inertia for rotation of a rod about this axis?
