冷却曲线

For each type of sample investigated, the crystallization exotherm became wider and shifted towards lower temperature range with increasing cooling rate.

结果表明，随着冷却速率的增加，每个试样的结晶放热曲线均变宽，并向低温区移动。

A new method for the separation and purification of chiral mandelic acid by heated benzene extraction and refrigeration crystal was established. The ionization constant of mandelic acid was mensurated by pH potentiometer titration.

采用pH值电位滴定法测定了扁桃酸的离解常数，采用高效液相色谱法考察了扁桃酸在不同溶剂中的溶解度曲线和在苯-水体系中于不同pH值条件时的分配率，建立了热苯萃取和冷却结晶的扁桃酸纯化工艺。

It should be added that in Figure 7-6 is only the characteristic curve of condenser for specific cooling water volume.

应该说明，图7-6只是对特定的冷却水量所作出的凝汽器特性曲线。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
