• 当当网：运费为书籍原价50％，最低50元。当当网书籍比较全，而且书价打折。例如一本书75折以后，加上运费，实际只多付25％的书价。支持VISA/MasterCard和Paypal支付。不过运输时间比较长，据称4－8周，实际运到德国需要2月时间。
  6月初曾在dangdang上定购中华书局《史记》一套10册，运费70左右，8月中旬到德国。
• 卓越网：被Amazon收购以后，提供多种海外购书方式，最便宜的一种60元每本，一套书运费依然按照本数计算，例如上述10卷本《史记》，运费将达600。卓越网据称可以比较快的送到，尚没有尝试，毕竟因此运费较高。
• 至于一些海外的小规模的网上中文书店，大都换人民币单位为欧元、美元，存量较少，现在并没有合适的其他选择。

Although I was such preocupied these days, but doing something while thing about its basic ideas is really interesting. There is less than two weeks for preparing the results and presentation. I am now worrying if I should present all my recent results at the next meeting in Netherlands, which will surely raise a lot of arguments from the experimental guys. Another thing is, I am still a freshman in this area. Maybe I just need more evidences.

The following is an interesting result from my calculation, descibing the thermal conductivity profile, which depends on both temperature field and local stains, after the heating of the experimental setup.
Pretty good, en? Still we can have some fun solving the engineering problems.

Next month, there are two scientists leaving from our institute, who are one American and one Indian. After that, this institute will be more "Germany" ever. When I spoke to the American female scientist, who was running a farewell party, she told me that after my graduation I could look for some positions in her new institute. But at that moment, our professor was present nearby, and he really made the sound "hei, hei, hei" to stop her further words. I can not keep laughing at this moment. That is really a joke.
