蚌

This is the elephant trunk clam, because tentacles looked like elephant the nose, so call it trunk clam.

这是象鼻蚌，因为触角长得像象鼻，所以叫它象鼻蚌。

Therefore,the experiment of clearance rate and filter rate of Anodonta woodiana was done in the lab to verify its effectiveness.

故以本论文於研究室中进行圆蚌的藻类滤除试验，以期在未来田间试验放养圆蚌中能够有所依据，达到最经济的且有效的处理效果。

Any of several freshwater bivalve mollusks of the genera Anodonta and Unio, found in the central United States, that burrow in the sand or mud of lakes and streams.

淡水蚌发现于美国中部的无齿贝属和珠蚌属几种淡水双壳软体动物的一种，在湖和河中的沙中或泥中挖洞

The safe concentration of Anodonta woodiana woodiana were: the available chlorine of bleaching powder of 95.25~108.86 mg/L, the available chlorine of trichloroisocyanuric acid powder of 3.32~3.55 mg/L.

试验得出漂白粉作用下，背角无齿蚌24h、48h、72h、96h、120h、144h、168h的半致死率；氯杀宁作用下，背角无齿蚌24h、48h、72h、96h的半致死率；漂白粉有效氯安全浓度95.25~108.86mg/L；氯杀宁有效氯安全浓度3.32~3.55mg/L。

To either the quantity of glochidia infested on host or the rate of juvenile, yellow catfish and grass carp were the best two hosts.

不论在寄苗量方面，还是在稚蚌脱苗率方面，黄颡鱼和草鱼均是三角帆蚌钩介幼虫的最佳寄主。

Approximate 80% of glochidia parasitized in silver carp, bighead and crucian carp did not metamorphosed successfully to juvenile until it broke off from host.

不论在奇苗量方面，还是在稚蚌脱苗率方面，黄颡鱼和草鱼均是三角帆蚌钩介幼虫的最佳寄主。

The rate of juvenile to glochidia parasitized in yellow catfish and grass carp was obviously higher than that in silver carp, bighead and crucian carp.

黄颡鱼和草鱼的稚蚌脱苗率显著高于鲢、鳙和鲫，寄生在鲢、鳙和鲫鳃上的钩介幼虫约80％未发育至稚蚌便提前脱落。

Approximate 80% of glochidia parasitized in silver carp, bighead and crucian carp did not metamorphosed successfully to juvenile until it broke off from host.

黄颡鱼和草鱼的稚蚌脱苗率显著高于鲢、鳙和鲫，寄生在鲢、鳙和鲫鳃上的钩介幼虫约80%未发育至稚蚌便提前脱落。

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。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
