“Have a nice day” may be a pleasant gesture or a meaningless expression. When my friend Maxie says “Have a nice day” with a smile, I know she sincerely cares about what happens to me. I feel loved and secure since another person cares about me and wishes me well. 

“Have a nice day. Next!” The version of the expression is spoken by a salesgirl at supermarket who is rushing me and my groceries out the door. The words came out in the same tone ( 腔调 ) with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else’s is the management’s attempt to increase business.

The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting at an end. Sometimes the expression saves us when we don’t know what to say. “Oh, you just had a tooth out? I’m terribly sorry, but have a nice day”.

The expression can be pleasant. If a stranger says “Have a nice day” to you, you may find it heart-warming because someone you don’t know has tried to be nice to you.

Although the use of the expression is insincere, meaningless social custom at times, there is nothing wrong with the sentence except that it is a little uninteresting. The salesgirl, the waitress, the teacher, and the countless others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it’s nice to know they care enough to pretend they care when they really don’t care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.

高效液相色谱是现代色谱科学、填料科学、电子科学等基础上发展起来的一种非常重要的分离检测技术,其分离原理、填料种类、检测能力都得到极大的提高,高效液相色谱的应用几乎包括药物研发到临床应用中的所有途径。

高效液相色谱广泛用于药物研究与生产的各个环节,掌握高效液相色谱系统基本构成非常重要。关于高效液相色谱的构造,叙述正确的是()

A.高效液相色谱的色谱泵通常在常压下运行,只需保持流速的精密度即可

B.蒸发光检测器是一种通用检测器,可以用于无紫外吸收药物的检测,但不可以用于挥发性物质的检测

C.色谱填料是色谱柱的填充物,也是色谱分离的核心,通常而言,填料为大小均匀、耐有机溶剂、表面对药物具有作用力的微球

D.色谱系统的管路、连接头、检测池对色谱柱效并没有明显的影响,所以高效液相色谱仪可以具有很长的流路管路

E.“塞状进样”指样品导入色谱柱后呈瓶塞状分布,与色谱柱有关而与进样溶液无关
