贻贝

In this paper, we selected 4different sites around the Jiaozhou Bay to monitor the environmental quaIity: Hongdao, Shuangbu,Tuandao and Huiquan Jiao. Hongdao is a typical fishery village, Shuangbu is an area with heavyindusny and densely population; Huiquan Jiao is a tourism point, Tuandao is an area with factories,transportation and tourism.Instrumental neut...

结果表明，蛤仔对大多数元素的富集作用最强，是胶州湾典型的指示生物；双埠蛤仔体内的As和Cr的含量已超出食品卫生标准；团岛贻贝体内的Cd、Cu和Zn的含量已超出食品卫生标准和一般底栖生物的最高允许浓度，说明胶州湾不同区域已有了不同程度的重金属污染，且年际变化较为明显，重金属污染程度在不断加剧。

Nevertheless, South African farmed production has shown a steady increase, from 3,000 MT (R 51 million) in 1997 to 4,100 MT (R 83 million) in 1998 and 5,800 MT (R 144 million) in 1999. In 2000, production was lower, at 4,030 MT (R 146 million) but this was due to the exclusion of Namibian oysters and mussels from South African statistics. Much of the country's farmed output, consisting of high value species such as trout, ornamental fish, abalone and oyster, is geared for export.

不过，南非养殖产量的增长比较稳定，从1997年的3000吨，增长到1998年的4100吨和1999年的5800吨，2000年的产量较低，但主要原因是没有把纳米比亚的牡蛎和贻贝的产量纳入南非的统计数位堙C南非的养殖产品中多数是高价水产品，如鲑鱼、观赏鱼、鲍鱼和牡蛎，这些产品主要是用於出口。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
