在水中的

The medical composite biological bone cement powder is mixture of apatite and polyamide component, and the polymaide component is fine powder formed by dissolving polyamide 6 or polyamide 66 in acetamide solution containing calcium chloride.

医用复合生物骨水泥粉由磷灰石和聚酰胺类成分组成的混合物，其中聚酰胺类成分为由聚酰胺6或聚酰胺66中的任一种溶解于含有氯化钙的乙酰胺溶液中所成的混合溶液在水中所形成的细粉。

Excellent underwater pelletizing technology guarantees stable cooling and cutting of plastic melt.Particles have extreme consistency and good appearance.

优异的水下切粒技术保证了塑胶熔体在水中进行稳定的冷却和被切割，使粒料具有无可比拟的一致性和外观质量。

One man, armed with a spear to which was attached a length of bark or creeper rope, would be paddled in a dugout canoe up to a wallowing hippo.

他会狠狠地将长矛扎进河马身上，然后迅速离开。由于扎在河马身上的长矛上系有一块浮着的小木块，潜入水中的河马挣扎便能发现。

The long-term and short-term effects of different propionic/acetic acid ratio and initial pH on the anaerobic and aerobic transformations of GAOs were studied.

2在丙酸和乙酸的碳摩尔浓度相同的情况下，GAOs吸收乙酸的速率较快，且在乙酸浓度适宜的情况下，GAOs对乙酸的吸收不需要长期驯化，短期提高进水中的丙酸量可抑制GAOs的生长。

Sample of trace nitrite in food and water were concentrated on a combination micro-fluidic chip with SPE micro-column, and examined on-line by a system of NaNO2—KI—Luminol. The contents of nitrite in Luncheon meat and tap water were 14.63mg/kg and 0.052mg/kg respectively.

在自制的复合式微流控芯片上，利用NaNO2—KI—Luminol发光体系，实现了午餐肉和自来水中痕量NO2—的在线分离富集、混合反应和检测，测得午餐肉中NO2—的含量为14.63mg/kg，自来水中NO2—的含量为0.052mg/kg。

The impact of life Life on Earth first emerged in the water.

对生命的影响地球上的生命最初是在水中出现的。

In my house we were so near that we could not begin to hear —— we could not speak low enough to be heard; as when you throw two stones into calm water so near that they break each other's undulations.

在我的屋子里，我们太接近，以致一开始听不清话——我们没法说得更轻，好使大家都听清；好比你扔两块石子到静水中去，太近了的话，它们要破坏彼此的涟漪的。

The results showed that the IVCW effectively removed total suspended solids(85%),chemical oxygen demand(50%),five-day biochemical oxygen demand(44%),total ammonia(53%),nitrite(83%) and nitrate(54%) from the aquaculture wastewater at a hydraulic loading rate of 420mm/d.

结果表明，在420 mm/d的水力负荷下，湿地可有效地去除循环水中的总悬浮物(去除率85%)、CODCr(去除率50%)、BOD5(去除率44%)、总氨氮(去除率53%)、亚硝酸盐(去除率83%)和硝酸盐(去除率54%)，能够满足养殖用水的要求，整个试验期间系统实现了零污水排放。

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。
