Bay scallops were introduced from the east coast of the U.S. into China to shorten the economic turn-over from 2 to 1 year. Parent scallops were carried to Qingdao on Dec. 20. 1982 and stocked in indoor tanks at controlled temperature and fed with a mixture of Phaeodictylum tricomutum, Pyrarnmonas sp. and Chhrella sp. They spawned on Jan. 26 of the next year. The larvae were reared at a temperature of 18 -21℃ and fed with Isochrysis galbana, Pyramimonas sp. and Chorella sp. In 4 weeks’ growing, the spats averaged 827um. They attained a height of 6.9 mm on May 9. In the middle of May, the seed scallops were transferred to Luoyuan Bay in Fujian Province, and Jiaozhou Bay, as well as the area off Taiping Jiao Cape, Qingdao, Shandong Province for experimental culture in plastic netcages suspended on a single line *** scallops cultured in . Luoyuan Bay grew to an averaged shell height of 10.4 mm. In Jiaozhou Bay and the Taiping Jiao Cape culture area, they grew to SO mm in average shell height

Using a 'three parameters' bottom model, the average sound intensity in homogeneous shallow water with constant depth is found by a better expression to be finite for normal mode number of water layer. The space structure of the sound field and some factors controlling the near, middle and far fields are discussed with this expression.

Radial profiles of local gas and solid holdups and liquid interstitial velocity were measured in a largediameter three-phase fluidized bed, and a systematic study was carried out in comparing the present data with those obtained in small-diameter beds. Radial profiles of local gas holdup were found to be parabolic; the distribution of local solid particle holdup could be expressed by Eq. (9); liquid interstitial velocity was well described by the modified circulating flow model.

提出了一种将RANS(Reynolds averaged Navier-Stokes)与DES(detached eddy simulation)相结合计算流场的工程新算法,并用于第一代载人飞船Mercury、第二代载人飞船Gemini、人类第一枚成功到达火星上空的Fire-Ⅱ探测器、具有丰富风洞实验数据(来流Mach数从0.50变到2.86)的巡航导弹、高升阻比的Waverider(乘波体)以及具有大容积效率与高升阻比的CAV(common aero vehicle)等6种国际上著名飞行器的绕流计算.在流场计算中,采用分区技术,即首先对全流场采用RANS计算,然后对分离较大或者分离较严重的那些区域采用DES分析技术.文中所完成的6个典型算例总共63个工况的数值计算表明:仅在分离较大的区域采用DES分析技术,虽然从严格意义上讲这样的处理并非真正意义上的DES,但这样近似处理后所得到的流场数值结果(其中包括气动力和气动热)与相关实验数据较为贴近,并且流场的计算效率较全场进行DES计算时要高得多.
