The paper introduces a new method for prediction of electromagnetic compatibility in the power system, and use the Electromagnetic simulation software ATP. By comparing the actual test results to the simulation results, it is proved that electromagnetic transient simulation is reliable and effective. It also introduces the Gray prediction theory to predict the next Electromagnetic Interference (EMI) of the substation. It is high practical to research and analyze the substation electromagnetic compatibility, and feasible to use the Gray prediction theory with multivariable for the model EMI prediction analysis.

Background: Identifying lignocellulose recalcitrant factors and exploring their genetic properties are essential for enhanced biomass enzymatic saccharification in bioenergy crops. Despite genetic modification of major wall polymers has been implemented for reduced recalcitrance in engineered plant, it could most cause a penalty of plant growth and biomass yield. Alternatively, it is increasingly considered to improve minor wall components, but an applicable approach is required for efficient assay of large population of biomass samples. Hence, this study collected total 100 rice straw samples and characterized all minor wall monosaccharides and biomass enzymatic saccharification by integrating NIRS modeling and QTL profiling. Results: By performing classic chemical analyses and establishing optimal NIRS equations, this study examined a diversity of four minor wall monosaccharides and major wall polymers (acid-soluble lignin/ASL, acid-insoluble lignin/AIL, three lignin monomers, crystalline cellulose), which led to largely varied hexoses yields achieved from enzymatic hydrolyses after two alkali pretreatments were conducted with all rice straws. Correlation analyses indicated that mannose and galactose could play a contrast role for biomass enzymatic saccharification at P < 0.0l level (n=100). Meanwhile, this study found that QTLs controlling mannose, galactose, lignin-related traits and biomass saccharification were co-located. Notably, by combining NIRS assay with QTLs maps, this study interpreted that the mannose-rich hemicellulose may assist AIL disassociation for enhanced biomass enzymatic saccharification, whereas the galactose-rich polysaccharides should be effectively extracted with ASL from alkali pretreatment for condensed AIL association with cellulose microfibrils against enzymatic hydrolysis. Conclusions: By integrating NIRS assay with QTL profiling for large population of rice straw samples, this study identified that the mannose of wall polysaccharides could positively affect biomass enzymatic saccharification, whereas the galactose had a significantly negative impact. It also sorted out that two minor monosaccharides should distinctively associate with lignin deposition for wall network construction. Hence, this study has demonstrated an applicable approach for fast assessments of minor lignocellulose recalcitrant factors and biomass enzymatic saccharification in rice, and it has also provided a potential strategy for bioenergy crop breeding.

Air conditioning is widely used nowadays. It brings comfortable life to us while gives some problems. Regional shortage of power supply has a great deal to do with the extensive use of air conditioner for long time. Against the background of low carbon economy, this paper choose 3 room types of 4 typical cities which have different habitable area and carry out a financial analysis of 4 types of air conditioning system(northern city has 5 types). So we’ll have a comprehensive and intuitive understand of economy of typical air conditioning system. It could help the selection of air conditioning system of different area and make good use of energy.

In the design and practice of landscape, the higher cost in landscape design often causes much more landscape resource waste, ignores the economic benefits of landscape and destroys its aesthetic sense. Through analyzing the relation between landscape and economy and introducing a set of concepts, planning, purchasing, manufacturing, marketing and service. In this article, we apply the theory of "supply chain management, SCM " in economics into the landscape design and its practice. To make the management more scientific, accurate, reasonable and efficient, we must keep two principles , reducing and controlling the cost and increasing its efficiency of landscape design and its practice. Also we may realize the organic coordination of the whole economic activities by this way.
