结合书中所学知识谈谈你对BIT技术的理解。

答案

参考答案:传统的测试技术主要是利用外部的测试仪器对被测设备进行测试,但随着复杂系统维修性要求的提高,迫切需要复杂系统本身具备检测、故障隔离的功能以缩短维修时间。所以BIT在测试研究当中占据了越来越重要的地位,成为维修性、测试性领域邪恶重要研究内容。BIT是指系统、设备内部提供的检测、隔离故障的自动测试能力。BIT技术是改善系统或设备测试性与诊断能力的的重要途径,是测试和维修的重要手段,简化了设备维护,降低了总体费用,它使得传统测试中用手工完成的绝大多数测试实现了自动化。

When I was a kid in Minnesota, watermelon was expensive. One of my father’s friends, Bernie, was a rich businessman, who owned a large store in St. Paul.

Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie’s place. We’ d sit on the edge of the dock(码头), feet dangling(摇晃), and got ready for a big meal.

Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we’d bury our faces in watermelon, eating only the heart—the reddest, juiciest, firmest, sweetest, most seed-free part—and throw away the rest.

Bernie was my father’s idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie’s wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.

What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don’t take the time to dangle your feet over the dock and enjoy life’s small pleasure, your work is probably hurting your life.

For many years, I forgot that lesson I’d learned as a kid on the loading dock. I was too busy making all the money I could.

Well, I’ve relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That’s the heart of the watermelon. I have learned again to throw the rest away.
