Osmosis: if you have salty water and fresh water separated by a filter, the salty water will suck up more water (from the fresh side) in order to dilute the salt.
【译】渗透作用：如果你有咸水和淡水被一个过滤器分离 ， 咸水会吸收更多的水（从淡水一侧） ， 以便稀释有盐的咸水 。
【用法】in order to 意为“为了……”，表示目的；在用法和意义上相当于so as to结构，但是in order to结构可以用于句首、句中，而so as to多用于句中 。其否定式分别为：in order not to 和so as not to 。in order to在句中表示目的时 ， 常可以转化成in order that 。如：We should work hard in order to pass the exam.=We should work hard in order that we can pass the exam.
