A kind of virus particles were observed in cytoplasm of sampled ill sea cucumber tissues which were sampled from sick sea cucumbers with ulcerous skin and swollen mouth from their farming ponds at the beginning of 2005. The particles were covered with a bilayer envelops, shaped in globular with its size 100-200 nm in diameter. The same virus was isolated from cultured sea cucumbers with disease from different time and sites, and then infected the healthy sea cucumber. sea cucumber appeared the phenomenon such as ulcerous skin and swollen mouth and the same virus was isolated from infected sea cucumbers.

本章从患病刺参中分离出了2株对刺参具有感染能力的细菌，经鉴定1株为弧菌科弧菌属Vibrio sp和1株为弧菌科施万氏菌属Shewanella sp；在患病刺参的触手、肠和呼吸树等组织的细胞质中，检出了球形、具双层囊膜、直径大约为100-200nm的病毒粒子利用分离的病毒进行人工感染实验，刺参可以产生与自然发病刺参相同的症状，显示了分离的病毒对刺参具有一定的感染性。

In this dissertation, InGaAs/InGaAsP/InP MQW microdisk laser and its characterization were presented. Some conclusions are as following: the characteristics of lasing threshold was discussed by using rate equation. The dependent relations between threshold and cavity volume, spontaneous emission coupling efficiency β were investigated. The whispering gallery mode and spontaneous emission in a microdisk geometry were then studied. Almost all spontaneous emission was coupled into the lowest order TE mode when the normalized thickness of photonics well was between 0.15 and 0.5. The design principle and device process of InGaAs/InGaAsP/InP MQW microdisk laser were presented. The microdisk lasers with the diameter of 8μm, 4. 5μm and 2μm were succesfully fabricated by using etching techniques. The pulse lasing thresholds for the microdisk with the diameter of 8μm and 4. 5μm were 170μW and 15μW, a record results compared with the published in the literature. The cw lasing threshold for a 2-μm-diameter microdisk was only a few μW. We haven't found similar report up to now. To solve the problem of directional output in a microdisk laser, the power coupling efficiency in a double disk geometry was investigated with the theory of waveguide mode couple. A new structure of electrically pumped microdisk laser with output waveguide was designed, making a foundation for the practical use of microdisk laser.
