According to the device operating principle and energy equipartition theory of thermodynamics,the mechanical-thermal noise is 9.96×10-9 W/Hz1/2,and the background noise is nearly 3.22×10-11 W/Hz1/2,so that the normalized detectivity is deduced to be 9.03×106 cm·Hz1/2/W.

Hz1/2/W。实验表明，器件的噪声中热机械噪声为主要噪声源，大小主要由浓硼硅薄膜的机械性能和器件结构决定，可以通过增大薄膜厚度，减小薄膜面积，从而增加薄膜的特征频率的方法来减小器件受外界振动的影响，但以降低器件的灵敏度为代价。

After theoretic analyzing support vector machine technique, the equipollence of support vector classification and regression problems is proofed, and a uniformed expression of support vector machine problem is gotten. The noise stained case is studied emphatically, and the experiment shows that a better result will be obtained by assigning weight factor to fit noise distribute characteristic. A multi-multiplier minimal optimization algorithm for norm-1 problems is deduced, and a kind of improved Gilbert geometric algorithm for norm-2 problems is introduced, which is applied in regression problems successfully.
