Using the autocorrelation function, the principal of homodyne method is explored. The relationship between delay time induced by delay fiber and characteristics of additive frequency-domain fluctuation affixed on homodyne beat noise photoelectric-current spectrum are intensively analyzed.

一、利用自相关函数研究了零拍法测量激光线宽的原理，重点考察了零拍光电流谱线上所附加的频域周期性波动，确定了该波动的频域周期与光纤延时线所产生的时延成反比。

The cell cycle and apoptosis and the expression of P-pg, bcl-2, P53 in the MG63 and MG63/R cell lines were analyzed by flow cytometry. Results The resistance index of the MG63/R cells to cisplatin was 83.557±4.841. The cells also had resistance to doxorubicin, vincristin, methotrexate and cyclophosphamide. Disordered structure of the MG63/R cells was observed through microscopy. The cells appeared in triangle, polygon and polynucleation. The increase of granular endoplasmic reticulums and apophyses was observed through transmission electron microscopy. The proliferation ability of MG63/R increased significantly, with a low apoptosis index.
