回复土村药师的评论:
我当年做的主要是致癌化学物在产品当中的分析。我们的要求是小于10PPB。做这种微量分析,需要使用大量的原产品,然后除去不要的东西,再浓缩致癌物。这都是在第一个柱子完成,然后再转到第二个高性能分析的柱子。最后检测器是用致癌物的衍生物反应器。英文就是Column Switching Technique with Post Column Reactor as Detector. 这个技术我相信当时是全美国在1979年第一个用在工厂做品质管制的分析技术。我们还拿到了美国的专利。关于分析复方或混合物,当然先用逆相,梯度来做。做梯度逆相,可以用短的柱子,然后用梯度的快慢来调节个个化合物出柱的顺序。当然,如果谈到中药的复方,首先是要萃取。除了典型的水煮外,也要使用不同的酒精和水的比例萃取。甚至用全部非极性的溶液。就是要把所有的成分给粹取出来。就是要下功夫去做,没有啥大学问。有问题随时赐教。谢谢。

也许中国太大了,中国人所以才不团结,就乡欧洲人之间老是要打仗。
犹太人在二战时候欧洲受迫害才到美国,但是美国到处是jewish center, jewish hospital。中国人比他们早到,但是没有Chinese center...,犹太人和中国人同样重视教育,但是文化传统上肯定有不少很不一样的地方。
Good to know that Europe is more open to Chinese, that is what I felt during my nearly 10 years living there, and also something that I really appreciate about European.
Unification is kinda gesture for the 2 sides of China, average people won't benefit from it, just like return of HongKong, mainlander still need a piece of permit paper for a tour spending money there.

I agree with what you have just said. I had an earlier blog about the comapny.

Under that circumstance, if you wanted to stay, you just had to follow the rules. Documentation at that time was useless. I moved to SF in 1988, the situation is totally different since then. I will get to that point in the future.
Concerning about Taiwan, I personally don't believe two sides will be united even I wish that will be happened. The problem is how far the China will go as far as democracy. Even we don't like the Taiwanese style, but for China to move to that stage is impossible. There is a big culture difference between two sides. As time goes by, the gap will be even wider. When I have time, I am going to discuss this in the future. Thank you.

我想不是别的原因,就因为我是个中国人.
Same thing could happen to a mainlander in Hong Kong as well. We like to generalize and blame something we cannot do about it. Wouldn't it be more productive if we know how to utilize the system and achieve our goals? Or take certain action for protect us. I know of a surgical nurse who was repeatly abused by a surgeon in the operating room. He kept it to himself for over two decades. (if he were a Chinese maybe he could take the same excuse). When he left his jobs, he showed all his documentation on the surgeon and sued both the surgeon and the hospital and won millions. My point is, do something productive about it. At least register and vote.
Another random thought on the future of Taiwan...
Obviously you are a very proud Chinese, probably more Chinese than I who is a southerner and can never speak mandarin well. (I can never tell the difference between "bed" and "boat" in Chinese pronounciation) Chinese government probably need to do more job to promote Chinese culture to the younger generation Taiwanese. Exchange students, scholarships, etc will be helpful. If the younger generation can be proud to be a Chinese, unification will take care of itself.
