自振

Furthermore, the dynamic model of ball end milling process is developed and corresponding simulations are made.

在上述基础上建立了球头刀铣削动力学模型，对铣削过程中的强迫振动和自激颤振进行了仿真。

The linewidth of output laser was less than 500 Hz measured through fiber delayed self-heterodyne method. The degree of polarization was stable at 99.7%.

通过光纤延迟自外差线宽测试系统得到输出激光线宽小于500 Hz，光纤激光器输出光偏振度长时间稳定在99.7%。

It can effectively solve the problem of global synchronized checking and self-checking of PMU precision in synchronized measurement networks.

在GPS同步时钟信号协调下，作者提出了利用对晶振信号进行整数分频生成PMU异地同步校核基准信号的方法，用于PMU装置的自校核和广域同步校核，彻底解决了广域测量装置无法校核的问题。

Numerous persons who are established businessmen have joined Yanxing with enthusiasm, and many of them are successful entrepreneur, such as Mr. Stan Shih. Stan is the founder of Acer Group. In addition to his great contribution to Chinese technology development, he established the "Stans Foundation" to support public welfare activities. Stan appreciates Yanxing's principle and practice, and has financially supporting nearly 200 Xioyans since 2005. Dr. Ronald Chwang , president of iD SoftCapital America is another key donator. Many other friends mainly from the venture capital and entrepreneur community, have extending their love and contribute greatly to Yanxing.

无数在事业上卓有成就的成功人士满怀热情加入到雁行中来，特别应提到的是著名企业家施振荣先生，施先生是宏碁集团创办人，在推动华人高科技发展的同时，成立&智荣基金会&，热心社会公益活动，颇为认同雁行的理念与作法，自2005年开始，已捐助将近两百名小雁，还有智基美国的庄人川博士以及活跃在中国的许多创投界和产业界的朋友为雁行贡献了爱心。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
