The point of a unit test is not to test every possible input, but to test a representative sample.

单元测试的关键不在于所有可能的输入，而是一个有代表性的样本。

For the COG joint subjected to thermal storage test at 80 oC for 1000hours, the resistance raises from 0.48 to 1.26Ω while in the sample, the resistance raises from 0.73 to 1.52Ω; all test results fit the reliability requirements. But the reason of increment is not only NCF material degradation cause, but also the bump is elastically. Therefore elastic bump resile caused the resistance to increase after pressing. Consequently I used another two samples which is not thermal aging compared to test samples, the results were show bump resistances increasing about 65%, its come form elastic bumps itself.

COG试片经过80oC约1000小时之后观察电阻上升情形，一片约从0.48Ω上升至1.26Ω另一片从0.73Ω到1.52Ω也符合可靠范围内，但是上升的原因不完全是胶材劣化导致，因为凸块本身具有弹性，所以在压合之后还会回弹造成电阻上升，因此会使用另两片未热时效的试片来比较，得知结果大概65％的电阻上升是来自本身具弹性导致。

The sum of BCOD of BODst test and XH measured through batch respirometer is consistent with the BCOD of BODlt test and the ratio between them was in the range of 0.88-1.02 with average 0.94. The BODlt test is time-consuming and the microorganisms'population and their metabolic characteristic are different from that of the actual activated sludge process. So the respirometry has the advantage of time-validity and representation for the actual activated sludge system.

6呼吸测量法测得的BCOD明显小于长期BOD测试方法的结果，这是由于后者得到的BCOD包括所有的活性微生物COD组分；短期BOD测试得到的BCOD与异养菌COD之和与长期BOD测试得到的BCOD比较接近，两者之比在0.88-1.02之间，平均值为0.94；长期BOD测试耗时长，测试用的微生物种群及其代谢类型都与实际活性污泥过程明显不同，因此，从测试结果的时效性和代表性方法考虑，短期BOD测试更具优势。
