Starting from the angle of engineering quality, construction managers shall make scientific and reasonable arrangement for the construction progress in the early stage, middle stage and later stage of building engineering, make every construction stage have definite key points in construction, and strengthen the reasonable judgment on the construction quality of engineering.
In addition, construction managers shall pay attention to the quality of construction materials, and control material quality in the sections like material selection, purchasing and transportation, etc.
Before purchasing of materials, we shall do comparative shopping, select the material suppliers having relatively good social image and the construction materials with relatively high performance-price ratio.
Also, we shall arrange transportation companies with high credit degree to complete the transportation of materials; and before delivering materials to construction site, we shall determine the quality of construction materials by means of spot check.

Introduction Cellulosic ethanol is produced mainly from the two major sugar components of glucose and xylose in lignocellulosic materials by bioconversion process.
Actually, we only have konwn little about the molecular biology and metabolic engineering on xylose fermentation microbes.
Materials and methods Strains, media and cultivation conditions Candida shehtae ATCC 22984 and Candida tropicalis CBS 94 were obtained from American Type Culture Collection.
Fuel ethanol production from lignocellulose: a challenge for metabolic engineering and process integration .
Xylose isomerase overexpression along with engineering of the pentose Phosphate pathway and evolutionary engineering enable rapid xylose utilization and ethanol production by Saccharomyces cerevisiae .

Research on the Key Technology of Polynaphthalene Sulphonate Preparation LI Yun Guangxi Economic Management Cadre College, Nanning, Guangxi, China 1246109544@qq.com Keywords: polynaphthalene sulphonate, sulphonation, polymerization, key technology, consumption reduction Abstract.
Given this fact, one of the biggest problems bothering the additive production in our country is the low resource efficiency, increasing shortage of materials, climbing price which would definitely contribute to a higher product cost.
Therefore, polynaphthalene sulphonate is not used directly but only after adding other ingredients according to construction requirements and local materials as well as weather conditions.
Conclusion By the research and improvement for key technology of coagulation polynaphthalene sulphonate production, project target reaches domestic advanced level, especially the naphthalene material consumption is only 0.25 ton per ton of powder, which is far less than the average level of 0.5~0.6 ton per ton powder, it plays certain role to relieve the problem caused by high demand for naphthalene material supply and resource shortage, and has evident economic and social benefits.

Since percolation-controlled grain boundary phenomena are involved and playing key roles in the generation of various kinds of bulk properties, the relationship between texture and grain boundary microstructure can be effectively used as a powerful tool in development of high performance structural and functional materials by Grain Boundary Engineering (GBE). 1.
GBE has been performed attempting at controlling intergranular corrosion and stress corrosion cracking in engineering materials such as stainless steels and nickel-based nuclear materials.
In fact, this has been taken into account through the characterization of triple junctions by OIM in recent studies of GBE for the control of severe intergranular brittleness in engineering materials [8-11].
The close correlation between texture, GBCD and GB connectivity may be used as a powerful tool for future grain boundary engineering for structural and functional materials.
