1. If you have a test list that contains three tests, and you check two of them, the check-mark for that test list will become dimmed, which indicates the indeterminate state. 如果有一个包含三个测试的测试列表，而选中了其中两个测试，则该测试列表的选中标记便会变灰，指示该测试列表处于不确定状态。
2. Example: If you have a test list that contains three tests, and you check two of them, the check-mark for that test list will become dimmed, which indicates the indeterminate state. 示例：如果有一个包含三个测试的测试列表，而选中了其中两个测试，则该测试列表的选中标记便会变灰，指示该测试列表处于不确定状态。
3. On this basis, the new logic indeterminate causal inductive automatic reasoning mechanism which is based on fuzzy state describing is brought forward. At the end of this paper its app… 在此基础上，又提出基于模糊状态描述的新型不确定因果归纳自动推理机制，并讨论其在智能控制器研制中的应用。
