海水的

A persulphate oxidation method in acid medium for decomposition and analysis of dissolved total phosphorus in seawater was proposed.

依此，建立酸性过硫酸盐氧化法分解测定海水中溶解态总磷的方法。

The influence factors on decomposition efficiency, such as digestion time and pH were identified. It was shown that non-condensed phosphate could be decomposed completely by persulphate.

结果表明：在碱性条件下过二硫酸钾高温氧化可使海水中非聚磷类化合物完全回收，而聚磷类化合物回收率不高，延长消化时间聚磷类化合物的回收率有一定提高。

The crop is salicornia. It is nourished by seawater flowing from a man-made canal.

这种作物就叫做盐角草属，由一条人工开凿的运河引海水灌溉滋养成长。

Carl Hodges is growing salicornia, a crop nourished by ocean water that holds the potential to provide food and fuel to millions.

卡尔。何吉斯正致力种植盐角草属，一种由海水供应养分的作物，有潜力提供数百万人粮食和燃料。

It should be about as salt as sea water 15 units on a salinometer

得到的盐水要像海水一样咸

Usually includes water depth 200 meter below the complete waters, is all year long dark, the sunlight cannot infiltrate completely, the salinity is high, the pressure high, the water temperature is low and is constant, the aquatic plant cannot grow, the animal type and quantity are deficient, and mostly is the detritus animal, only then the few sarcophagy animal, and along with the sea water depth increases, but reduces unceasingly.

通常包括水深200米以下的全部水域，终年黑暗，阳光完全不能透入，盐度高，压力大，水温低而恒定，水生植物不能生长，动物种类和数量非常贫乏，且大多属碎屑性动物，只有少量肉食性动物，并随海水深度增加而不断减少。

To investigate the sea water quality and sedimental envirenment,12 sampling points were made in the sea area of Tieshan port(109°30′￣109°36′ E,21°25′30"￣ 21°31′30" N).

为了解铁山港海域的海水水质与底质环境现状，在铁山港海域（109°30′～109°36′E，21°25′30&～21°31′30&N）设点12个。

It is signality to exploit open - sea aquicuhure for development healthily and continually.

开发近海开放型海域发展水产健康养殖是海水养殖业可持续发展的必由之路。

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。
