Based the thesis that scientific research rules depend upon suppositions of points of view of nature,after intense investigation on Repeatability Principle,the author claimed that Repeatability Principle is not self-evident a priori Principle,the validity depends upon suppositions of point of view of nature.

The science of journal editing, with abundant meaning, requires editing staff to have strong spirit of science and follow scientific principles.

The author points out that scientific concepts of editing are the basis for building the theory of editing, and the author also presents scientific principles for establishing scientific concepts of editing which include the application of philosophy,unity between theory a.

Discovering New Neural Network Learning Rule Based on Genetic Programming;

The weights of the principal component neural networks are trained with the aid of the algorithm of generalized Hebbian learning rule, and the input vectors of the local spatial features and image pixels value are transformed into feature vectors which are once clustered by Kmeans classifier, the road surface and unroad surface can be distinguish.

In this neural network training, the author applied an error back-propagation gradient descending search technique successfully, and then proposed a new learning rule for multiple pattern pairs fuzzy associative memories in single FAM and its efficiency has been confirmed by computer imitations.

The rules are made up by the method of rules learning,which can strengthen the portability of the system.
