脱水

The onset of syneresis appeared at a critical Crdensity in a gel and the syneresis became serious when the Cr density increased.

It has offered the information of the boiling points of the chemical compounds, and it is helpful to reutilize them after their separation by rectification. The results showed that the main compounds of the heavy cut of terpineol were longifolene and βcaryophyllene. They are from the raw material, terpinene oil.

松油醇的合成工艺方法主要有两种：一种是一步法，即松节油在酸催化作用下直接进行水合反应生成松油醇；另一种是二步法，即松节油首先在酸催化作用下水合成萜二醇，再经稀酸催化脱水生产松油醇。

A pilot test with a feed flux of 12 × 104 m3/d was carried out.

But the titanic acid nanotubes were thermally unstable.

发现钛酸纳米管在高温时向锐钛矿结构转变，相转变的机制是由于纳米管在热力学条件下层间和层内进行脱水，正交结构遭到破坏后结构进行重新排列而导致的。

The nurse should consider the BUN level, along with the patient's vital signs, intake and output, weight, and skin turgor as potential indicators of dehydration.
