It not only carry the change student task from middle school chemistry learning to university chemistry learning, but also is the foundation for subsequent chemistry lesson and relevant professional lesson.
To adapt to the independent college teaching need, we think general chemistry course should be set, but general chemistry course must be reformed.
General Chemistry Teaching Situation and Problems Importance of Chemistry Basic Course is Decline.
After using multimedia, students not only can see the bonding material spatial structure, but also can observe bonding process through flash.
Because of less period, general chemistry often only emphasizes the chemistry theory, and does not pay attention to the application of chemistry knowledge.

"Click chemistry" is a new method to synthesis massive chemical compound after combinatorial chemistry.
The structure of modified HA was characterized by FTIR and 1H NMR.
It is clearly that there was three-dimensional net structure with porous.
Formation of HA hydrogel was not only provided by crosslink net structure, but also by filamentous crosslink between porous structures.
And the structure of HA hydrogel was more compact.

Positronium Chemistry in Polymeric Membrane Systems
Y.C.
Introduction Positron and Positronium (Ps) chemistry is usually considered a branch of traditional nuclear chemistry [1].
However, due to the richness of the positron annihilation process in molecular systems, it has developed into four traditional areas of chemistry discipline: analytical chemistry, inorganic chemistry, organic chemistry and physical chemistry and beyond.
This 3-layer structure is also seen in the R parameter vs. depth (lower plot of Fig. 3).
The lines for flux were fitted in an exponential function of free-volume theory. [31,32] probability (inhibition effect), which is even more sensitive to chemical structures and radiation chemistry of materials studied.

Specially, it plays an important role in medical chemistry teaching.
So, teachers should consider the problems about how to overcome the disadvantages of multimedia classroom teaching and build new-type teaching structure and teaching mode that can reflect the subject role of students.
The content of this course is mainly related to the relationship between chemistry and medicine, and the further application in medical chemistry.
Multimedia teachingmakes it convenient to show chemistry experiments: Chemical experiments play an important role in medical chemistry teaching.
Multimedia teaching can’t replace the real-world chemistry experiments: Medical chemistry is an experimental science.

Abstract.
This article focuses on the discussion about coal desulfurization and its relationship to green chemistry.
The traditional chemical desulfurization method is not affected by the coal sulfur distribution, size and crystal structure of the desulfurization reaction, but during the process, it needs to use corrosive leaching agent and strong acid condition, which not only affects the calorific value of coal and adhesive, but also causes a serious impact to the surrounding environment.
The Combination of green chemistry and desulfurization of coal not only reduces coal burning pollution on the environment, but also provides a powerful guarantee for the application of green chemistry in other industrial production.

The soil structure had been improved, and soil moisture was been kept more easily.
However, the structure of recovering vegetation in 10-year samples were more complex than that in 3-year.
M unrelated with physics and chemistry characters of soil.
Soil structure was improved and soil antierodibility was enhanced.
Structure of recovering vegetation became more complex, and spatial distribution became more evenly.

This dissertation analyzes the necessity of humanities education infiltrating basic chemistry courses of science and engineering, studies the method of humanities education infiltrating basic chemistry courses, and carries out a beneficial attempt to integrate the content of humanities education with that of basic chemistry courses.
Introduction Basic chemistry is a basic course of science and engineering majors such as medicine, pharmaceutical, biochemical, food, environment, textile, metallurgical and others including the basic knowledge of inorganic chemistry, analytical chemistry and organic chemistry and so on.
Priestley, English chemist, said, chemistry was a science serving for the greatest happiness of most people.
As a result, students are in a weak condition of humanity accomplishment commonly, which causes that students can integrate the depth and breadth of chemical knowledge organically leading to incomplete knowledge structure.
