By utilizing the cross-gain modulation effect and the period-one oscillation harmonic frequency-locked in an optically injected semiconductor laser, we can extract the wavelength conversional individual channel optical clock from the optical-time-division-multiplexing signal. In a FP-LD, we numerically simulate the extraction of 20 GHz optical clock at 1550 nm from the 2×20 Gb/s OTDM signal at 1555 nm, and experimentally obtain the -105 dBc/Hz phase noise frequency division clock of 12.36 GHz to 6.18 GHz with simultaneous wavelength conversion from 1550.24 nm to 1545.91 nm.

The use of assets for impairment adjustment of profits According to the Ministry of Finance, in 1999 and 2001 respectively, the implementation of the new accounting system, would require a total of eight Provision for impairment, in the Provision for impairment of the year, profit was not affected, and the year after back-impairment Preparations that can increase profits, some listed companies to take full advantage of this policy, previously extracted large amounts of impairment, and after a variety of meaning that those who have the impairment of assets each year restoration of the original value, so back - Have mentioned impairment, inflated profits, as for the impairment of assets and revaluation itself is difficult to define a subjective issue, after preparations for impairment from increased profits from the source.

九、利用资产减值准备调节利润根据财政部的规定，在1999年和2001年分别执行新的会计制度，共需计提八项减值准备，在计提减值准备的当年，不影响当年利润，而以后年度冲回减值准备时则可以增加当年利润，某些上市公司为充分利用这一政策，先前提取大额减值准备，而以后以各种各义说明那些已减值资产逐年恢复了原有价值，因此冲回已提减值准备，虚增利润，至于资产的减值和升值本来就是一个难以界定的主观问题，提取减值准备为以后增加利润提取了来源。
