In this paper, the processes of electroless Ni-P, Ni-Fe-Co-P and Ni-Co-B platingwere investigated by using graphite pieces as samples first, and then Ni-P, Ni-Fe-Co-Pand Ni-Co-B coatings were deposited onto carbon nanofibers by using the selectedelectroless processes. The composition, structure of the coatings and the properties ofthe metal-coated carbon nanofibers were also studied.

Experiment results show that the mechanical-thermal noise coming from the structure and the mechanical performance of a heavily doped Si membrane is the main noise of the device, which can be reduced by minishing the membrane area and extending the membrane thickness to increase the mechanical resonant frequency of the membrane, but should be at the price of reducing the sensitivity of the device.

Hz(上标 1/2)/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。
