界定了端口的故障类型，据此对系统级诊断中的通用测试无效模型进行扩展。
Furthermore, the generalized test invalidation model is extended based on the given fault types.
在采用溶液（1）得到的色谱图中，相应的氯化钠峰和三氯氨铂峰之间的分离度不小于2.0，否则测试无效。
The test is not valid unless, in the chromatogram obtained with solution (1), the resolution factor between the peaks corresponding to sodium chloride and trichloroammineplatinate is at least 2.0.
例如，如果生产机器有6个400hm的CPU，那么测试机器也应该有6个400hm的CPU；否则，随后的测试将是无效且不可靠的。
For example, if the production machine has 6 400hm CPUs, the test machine should also have 6 400hm CPUs; otherwise your subsequent tests will be invalid and not reliable.
