机电控制理论考试算是考完了，考得还不错，运气好的话应该有90＋，不过听说我的老师关人多是出了名的，虽然我肯定不会挂。
接下来还有很多事要做。两篇文章，虽然都不怎么重要，但都是要写的。重要的是机电控制的课程设计。
课程设计做的是单片机的应用，要用protel99画电路图。以前没用过，正在努力学习中，刚刚找到了设计要用的8031单片机，扩展存储器件，以及74LS138等小元件。现在仅仅是试用，构思以及大致的电路草图还没出来。
这个设计的东西比我们学的东西要深很多，编程估计要大段大段的，而我到考试之前才会了一个ADC0809的采样和中断编程。
下学期课程不多，好像说是15.5个学分，加选修应该不超过20个，以前都是30＋的。
1. More and more people start using Gmail as their major mailbox.
2. While I walked across a crossroad, I heard an old woman giving many thanks to a police who pulled her back while the light was still red. “Healthy body and good luck”, she said many times.
3. My grandmother is concerning about “the return of Taiwan”, and she is very happy about Lanzhan and Song Chuyu’s visits to mainland. And she talked a lot about it while we are on the phone.
Record down as MEMO.
