If you read of an experiment with real developers working for a week, and this shows an improvement in quality of design when using TDD, can we count on the results?

如果你看到一个调查报告，上面写着一些真正的开发人员用一星期的时间做了一个实验，结果表明使用TDD可以提高设计质量，我们真的能把它当真么？

It is proved by experiment results that rational design and strict technics control play important roles for shortening the turn-on time of high frequency thyristor effectively.

而实验结果证明只要设计合理，工艺上严格控制，就可有效地缩短高频晶闸管的开通时间。
