I use one teaspoon per gallon when I initially set up a tank, then about once a month make a partial water change, adding the same ratio of salt to the new water.
当我设立新缸时，我习惯在每加仑的水中加入一茶匙的海盐，然后等过一个月后再换部份新水同时再加入同样比例的海盐于新水中。
A partial meltdown can occur when radioactive fuel rods, which normally are covered in water, remain partially uncovered for too long.
通常燃料棒处于水中，一旦有部分长时间暴露于水的话，就会熔化。
The annual water quality reports that utilities are required to send customers provide a partial picture, the study says, as they contain no information on unregulated chemicals.
这项研究表示，自来水公司会按要求每年向客户提供年度水质报告，包括部分照片，但他们没有提供关于法律限定之外化学物质的任何信息。
Reports suggest there was a partial meltdown and that the zircalloy rods began to "bubble". This was why the reactors were flooded with sea water.
报告表明有一部分溶毁并且锆棒气泡化，因为反应堆被海水淹没。
Pumps do not actually suck ; rather , pumps create a partial vacuum into which atmospheric pressure pushes water via the suction pipework.
水泵并不是实际的吸：更确切的说，水泵产生非完全的真空，然后大气压力将水通过吸管推进水泵中。
Spherical pellet shape also makes a positive contribution during the drying process which functions due to the differential partial pressure of the water vapor between the pellets and the drying gas.
这种球形颗粒形状在加工过程中也起到积极作用，其功能体现水蒸气在球形颗粒和干气之间具有不均匀压力。
The higher the water temperature , the more likely it is to boil when exposed to a partial vacuum , thus reducing suction lift.
水温越高，在局部的真空下水更容易煮沸，因此减少了扬程。
Conclusion the partial saturation technique is highly valuable in the MR abdomen water imaging. It is a recommendable method for MR abdomen water imaging.
结论：局部饱和技术有很高的临床应用价值，值得在腹部MR水成像中应用推广。

本文首先指出WK B方法可适用于更广泛的一类方程，并把它应用于线性化浅水波方程。
More specifically, we can say that there is a trend towards equilibrium between the water vapour pressure in the product and the partial pressure of the water vapour in the air.
我们可更准确地说，是产品内部的水蒸汽压力与空气中部分的的水蒸汽压力之间有一种趋于平衡的趋势。
More specifically, we can say that there is a trend towards equilibrium between the water vapour pressure in the product and the partial pressure of the water vapour in the air.
