Besides, it is also a multi-fundamental material which can be used in surface treatment for metal, biomedical cements and phosphor material.
Many attempts have been made to modify the preparation or particle size of zinc phosphate, one of which is to change solid-liquid reaction to liquid-liquid phase by adding other raw material.
In addition, cheap low grade commercial ZnO can be used as a raw material comparing with the solid-liquid reaction in ZnO-P2O5-H2O system.

Abstract.
The as-cast grain size of aluminum alloys is generally greater than 100 µm, and grain refinement is achieved by thermomechanical processing routes involving static recrystallizion of a cold or warm worked material or dynamic recrystallization [1].
In the presented data, Journal Title and Volume Number (to be inserted by the publisher) 3 200 µµµµm (a) 100 µµµµm (b) 1 µµµµm (d) 100 µµµµm (c) Fig.1.
At ε∼8, these arrays occupied almost all the unrecrystallized material volume, and at ε∼12, mixed arrays consisting of LABs and HABs were evolved (Fig.1d).

Introduction Lanthanide trivalent ions are effective for luminescent materials because of their excellent quantum efficiency.
In this research group, an europium complex with a dihydroxy derivative of trans-1,2-dipyridylthene, α- pyridoin, and containing oxygen and nitrogen donating atoms is prepared and tested for the possible electroluminescent materials.

And it has been in continuous progress and perfection, with the development of society and the progress of science and technology, the dynamic characteristic is being strengthened constantly; On the other hand, as a specific commitment of university engineering undergraduate teaching practice, a professional teacher’s theoretical knowledge, knowledge structure, ability and means reflected more changes in teaching behavior.
As a professional teacher, must pay attention to and strengthen the scientific research work, absorbing materials, results from others, the innovation of research results, and its application in teaching practice.
In the teaching practice of undergraduate major in engineering, the success or failure, the quality of engineering undergraduate education and training largely depends on the knowledge structure of the professional teachers, especially in science and technology combining with each other today, this point seems keep more special significance.
