Introduction With sound development of computer science and artificial intelligence, e-learning will become increasingly important in network education or learning after class.
Because fields related to basic science and methods of solving problem belong to the objective maturity theory, so intelligent tutoring belongs to automatic processing of objective maturity problems.
The system can serve as not only a tool for the students learning and tutoring, but also an assistant to teachers inquiring relative material.

In the era of big data, it is unrealized to collect information only by humane because it needs a lot of manpower, material resources and time.
The group should be consist of staffs from different professional such as from computer science, mathematics, sociology, law, management science, political science, and psychology.

In addition, read by noise meter is uncertain for some materials with lower HV hardness and lower tensile strength, even lower than press machine’s no-load noise value.
It is clearly defined that Eq. 2 only applies to those materials whose HV hardness is from 10 to 600[5].

Introduction Aluminum alloy is one of the most widely used metallic materials at present.
Also we deduced the tin salt conversion coating is a crystal structure material because the two diffracted peaks are aiguilles.
The coating is a rystal structure material and its crystallinity is better than uncoated sample.
