蚌类

Barnacles, mussels, algae and other types of shellfish grow on the boxcooler and thus affect its heat transfer function.

藤壶，蚌类，藻类和其他海洋生物生长在箱式冷却器中，从而严重影响了它的热转换功能。

I normally eat seals but also can dine on walruses , mussels or even berri es and seaweed.

我通常吃海豹，但也能吃海象，蚌类，甚至是浆果和海藻。

Fisheries are mainly tilapia, crab, soft-shelled turtle, quality carp, white butterfish, white shark, fish, catfish, the United States to fish, Macrobrachium nipponense, eel, loach, such as mussels.

My friend Tony the floor broker and I had been drifting along in his sloop for the past hour, waiting for the two o'clock southerly to come in and send us scurrying over to the North Shore of Long Island Sound for some of City Island's specialty-fresh clams and mussels.

我和好友场内经纪人东尼躺在他的单桅帆船上，了无生趣地泡了一个小时，等候两点钟的南风，把我们送到长岛沿海的北岸，享受一些海鲜——新鲜的海贝和蚌类。

Techniques and equipment to exploit their environment, basing their economy on fishingin streams and coastal waters that teemed with salmon, halibut, and other varieties offish; gathering abalone, mussels, clams, and other shellfish from the rocky coastline

他们是基于大量出现鲑鱼、大比目鱼和其他多种鱼类的自身流域和水岸捕鱼的经济；基于从落基山水岸聚集了鲍鱼、蚌类、蛤和其他贝壳动物的经济；基于捕猎地域和海洋哺乳动物的经济；以及基于收集野生植物的食物的经济。

Scallops and mussels add zinc and iron to your body.

贝类和蚌类海产品可以增加我们的身体对锌和铁的需求量。

The results show that the DNA extraction method based on Sambrooks method is relatively simple and easy to obtain high quality genomic DNA from freshwater unionid species.

结果表明，基于Sambrook的方法改进的DNA提取方法不仅步骤简单，而且提取的基因组DNA分子大、质量高，适合淡水蚌类基因组DNA的大规模提取。

The genomic DNA of Unio douglasiae, collected from Suya Lake, Henan Province, was used as template DNA to optimize the RAPD-PCR reaction conditions including the concentration of DNA template, random primer, dNTPs, Mg2+ and Taq DNA polymerase and the annealing temperature for thermal cycle.

以河南宿鸭湖圆顶珠蚌的基因组DNA为模板，对淡水蚌类RAPD反应体系中的模板DNA浓度、随机引物浓度、dNTPs浓度、Mg~(2+)浓度、Taq DNA聚合酶浓度和和热循环参数中的退火温度进行了优化。

Therefore, RAPD markers was used to detect genetic diversity of twenty populations of eighteen species from ten genera in Chinese Unionidae, its phylogeny were studied employing the combined analyses of RAPD markers, rDNA ITS1 sequence analysis and shell morphometrics.

为此，本研究采用RAPD技术对我国10属18种蚌类20个群体的遗传多样性进行了分析，将RAPD标记与rDNAITSl序列分析、贝壳形态度量分析相结合对我国蚌科的系统发育进行了研究。

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。
