In order to make sure the magnetic field distribution around the magneto optical trap cold atoms, the weakvariation and distribution around the zero point magnet field can be analyzed.
为了研究磁光阱冷原子团所在区域的磁场大小，从而得出磁场零点附近磁场的微弱变化及其分布。

If the variation of input weak signal can be reflected by certain word length, the output SNR mainly depends on the word length of adaptive operations.
如果某个量化字长能反映出输出弱信号的变化，输出信噪比主要取决于自适应运算的字长。

The simulated extraction of weak frequency variation signal is carried out with the expressed Resonant frequency locking property when system transits from chaotic to great periodic motion.
