On Reasoning Forms of the Investigation of Combining Cases

The analogy reasoning means are similar on some characters according to two or more targets, attributing to be (similar) on other characters, but it doesn't repel analogy reasoning that is the same on some characters according to two or more targets, putting out the same (reasoning) on other characters of these targets. Analogy reasoning is a kind of (independent) reasoning form. In the investigation of combining cases, the reasoning form is the analogy reasoning, not suming up reasoning. And the analogy reasoning can divide into the similar filling vacancy and merging analogy reasoning.
