Functions of construction project management fall into four aspects: specifying project objectives and plans, maximizing resource efficiency through procurement of labor, materials and equipment, implementing various operations through proper coordination and control of planning, design, estimating, contracting and construction in the entire process, developing effective communications and mechanisms for resolving conflicts [3].
The data can be prepared based on English teaching materials Modern Construction Management, by Frank Harris, Ronald McCaffer and Francis Edum-Fotwe, published by Wiley-Blackwell in 2012.

Lycium barbarum as raw materials, after press, enzymatic hydrolysis, separation and drying process to a series of different Lycium barbarum products, through determination of effective ingredients content, such as carotenoid, amino acid, crude protein, crude fat, tried to explore the influence of effective component on different processing methods.
However the Lycium as the raw materials, the changes of active substance content in process products, has not been reported in the literature with detailed.
Materials and methods Materials Fresh Lycium: produced in the County of Ningxia.
Yao W.B[8] research indicates that high temperature can make the above material denature, solubility reduce, then activity also loss.

Study on the application of modified Chitosan in Cherry preservation Li Yu-feng1,2,a ,Zhu Shi-Fu1,b ,Zhu Xue-jun2,c 1:Department of Materials Science,Sichuan University,Chengdu ,China 2:Key Laboratory of Fine Flake Graphite Deep Processing, Panzhihua College, Panzhihua ,Sichuan Province, PR China a: lyfpzh@163.com b: sfzhu@scu.edu.cn c:zxjpzh@163.com Key words: Cherry; Chitosan; preservation Abstract: To obtain a good Cherry preservative, the author prepared acetic acid Chitosan and metal ion complexes with solid-liquid reaction.
Besides, the Cherry preservative was prepared by modified Chitosan materials.
Experiment Materials.
Thereby, the application of chitosan modified materials can effectively maintain the quality and extend the cherry harvest life and the modified chitosan has huge potential in application of coating edible fresh fruit.
