In this paper, the practical WDM multi-granularity traffic switching testing network is constructed and a novel method using eye diagram to monitor optical performance in the network is proposed. The method is demonstrated in the reconfigurable WDM multi-granularity traffic switching all-optical network and it results that it can realize supervision of optical signal to noise ratio, time jittering, channel power, extinction ratio and bit error rate of optical data stream of any wavelength channel in the network. The method is transparent to signal protocol and bit rates and is able to distinguish between different optical impairments.

In addition, we analyzed the rule of atmospheric transport and diffusion, and took the Frequency of lake and breeze to modify the data of atmospheric capacity of Yueyang, which was achieved by A-P index, and compares the modified data of atmospheric capacity with the data of atmospheric capacity achieved by multi-source. The results indicated that according to the fact of lake and breeze, taking the frequency of lake and breeze to modify the data of atmospheric capacity of the field with stable lake and breeze, which is achieved by A-P index, made the atmospheric capacity more accurate. Accordingly, the result could be more reliable if the modified data is taken to calculate the atmospheric capacity when we assess the impact on the environment of the field with stable lake and land breeze.

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
