But , the measured - data is a very great quantity and every data contain all data of 1 - 25 harmonic , measured time can have hours to days . the count by hand is very heavy and over - elaborate , sometimes the statistics results is error . it won " t reach the analysis purpose and don " t obtain the curve of harmonic oscillation characteristic in a row frequency range 可是，测试数据经常是大量的，每一组数据又包含从基波到25次谐波的所有数据，测试时间可能是几个小时，有的甚至是几天时间，这样的工作量由人工完成是非常繁重的，又是非常繁琐的，有时还统计不出正确的数值，起不到应有的测试分析目的，更无法获得连续频域内的谐波谐振特性曲线。

In addition , the author also research in general detection optimal algorithm used by fault diagnosis system , these detection optimal algorithm can classify into two types , the first type is that algorithm must be able to find the ptvs ( parallel test vector ) which has the best condensing index p under fault location precision request , these algorithm include woa optimal algorithm , true / compliment optimal algorithm ; the second type is that algorithm must be able to find the ptvs which has the best fault location precision under the condensin index p request . these algorithms include minimum weight value optimal algorithm . but these general detection optimal algorithms have a lot of flaw in test time cost or low fault coverage rate 本文作者还对测试优化算法进行仔细研究，研究结果表明测试优化算法可分为两类，第一类是在满足给定故障定位精度的前提下寻找能够实现最优紧凑性指标p的ptvs (并行测试向量集) ，如true compliment算法；第二类是在满足给定紧凑性指标的前提下寻求能够实现最优故障定位精度的ptvs ，如极小权值优化算法，研究结果还显示这些常规的算法存在测试时间长、故障覆盖率低的缺点。
Firstly , the multilayer functional model was established which was based on the operation flows and then the test cases were created and performed . secondly , the safe regression technique was used to analyze the testing . finally , the modification - based regression technique or the cost - based regression technique was taken according to the time and the finance of the project 该技术首先依据业务流程建立多层次功能模型以及在该模型基础上生成测试用例和执行测试，之后在已经建立的多层次功能模型基础上进行安全回归测试分析，其次根据测试时间和资金的限制进行基于变更的回归测试分析或基于代价分析的回归测试分析。
On 8 , we measured the distilled water by using different electrical current 100 ma and 200 ma to define the electrical current influence on the result , and founded that the electrical current hasn ’ t distinct influence on the test if the test time can be controlled out of the natural convection 控制测试时间可以有效避免有限液体边界对测试的影响,测试时间应控制在3s以内。用该仪器对蒸馏水和乙醇进行的测试结果表明:瞬态双热线导热系数测量具有较高的精度与回复度。
