SHENZHEN, March 25 (Xinhua) -- Chinese scientists, in collaboration with their counterparts from the Republic of Korea, have observed the dissolution process of salt in water at the atomic level for the first time using a single-ion control technique and successfully controlled this process. The ...
such as navigation instruments, electronic communication equipment, etc., it is necessary to choose a high-precision filter. For example, for some high-precision electronic sensors, a filter that can filter out salt spray particles smaller than 1 micron in size, such as a glass...
There are so many different definitions and ways on how to filter and purify water, but I’ll try and keep it simple. The main thing you need to do is filter out the big stuff, and then purify the water from any lurking bacteria, germs, or other harmful things that could make you s...

Physical filtration means straining water to remove larger impurities. In other words, a physical filter is a glorified sieve—maybe a piece of thin gauze or a very fine textile membrane. (If you have an electric kettle, you probably have a filter like this built into the spout to remove ...
Everyone needs to stay properly hydrated, but some population groups are more vulnerable to risks associated with not getting enough fluids, including: Anyone using diuretics, a type of medication that removes extra salt and water from the body when you urinate, is at higher risk for dehydration...
解析 A 细节题。在文章开头有一段话:One of these is the subtraction of water from the ocean by means of evaporation―conversion of liquid water to water vapor.In this manner,the salinity is increased,since the salts stay behind.这段话告诉我们食用盐就是利用这种蒸发(evaporation)方式形成的。
