Applicability Study on Voltage Levels for New Urban District With High Load Density

Power System Technology (2014)

Mao Xiao-min

To search after the applicability of voltage class combination scheme for new urban district with high load density,a mathematical model to simulate integrated programming of substations and power network in planned district is proposed and solved by particle swarm optimization algorithm. The construction scales and economic indices of voltage class optimization scheme for three voltage class combinations,i.e.,the combination of 220/110/10 kV,the combination of 220/110/20 kV and the combination of 220/20 kV,under various load densities and four kinds of equipment selection are attained and compared. Research results show that when load density reaches to 10 MW/km2 and above it is suitable to take the voltage class of 20kV for medium-voltage distribution,and the voltage class combination of 220/20 kV possesses better economy under various equipment selections than voltage class combination of 220/110/20 kV.

Research on calculation and analysis of recruitment cost in a tertiary hospital

Chinese Hospitals (2012)

Mao Xiao-min

By informant interview and data collection from relative department in hospital,recruitment related cost during 2007-2009 was calculated and analyzed.Research showed that the top three items of recruitment cost were staff's compensation,physical examination fee and quality development fee.There is about50%-60% of variable cost and 40%-50% of fixed cost in total recruitment cost.

The Suggestions of Crops Production Based on the Water Use Condition and the Comparative Priority Index

Journal of Irrigation and Drainage (2009)

Mao Xiao-min

This paper applies the comparative superiority theory to select 11 kinds of crops as the representative crops in Tianjin.This study calculates the water requirements of crops and the effective precipitation and elicits that the comprehensive field ET of Tianjin is 524 mm.Finally,this article analyses the water use condition and the comparative priority index of each representative crop and classifies the crops as four kinds.Grape,maize and cotton are the significant corps of Tianjin.Heliotrope's growth dimensions could be maintained and put emphases on how to increase the output.The growth dimensions of wheat should be compressed.Rice,soybean,broomcorn,fruit tree and melon are the common corps which should not be considered as the key crops to develop in Tianjin.

Method of minimum flux in saturation layer for calculating stable water infiltration through layered soil

Journal of Hydraulic Engineering (2010)

Mao Xiao-min Songhao Shang

Based on the principle of soil water dynamics, a new method called the method of minimum flux in saturation layer (MFSL) for calculating the stable infiltration rate from multi-layer soil was proposed. The HYDRUS-1D was applied to simulate a series of infiltration processes with different surface water head, and under different hydraulic properties in the layered soil. The simulation results provide a standard to verify MFSL. The results show that MFSL tend to underestimate the stable infiltration rate, yet mostly less than 5%. Therefore MFSL is a method with clear physical background and less error. Compared with the modified Green-Ampt model for calculating infiltration through layered soil, MFSL does not need to consider the water entry suction in the lower soil layer, and can deal with the complexity of the multi-layer soil characteristics presented in reality. Therefore, MFSL is more suitable for the estimation of stable water infiltration rate in layered soil. It provides a convenient and useful tool for water resources evaluation, environment contamination evaluation, and the related projects design.

The Applicability and Application of AquaCrop Model

Journal of Irrigation and Drainage (2011)

Mao Xiao-min

AquaCrop model driven by water is a new crop simulated model recommend by FAO.In order to evaluate its applicability in North China,this irrigation experiment for summer maize was conducted in two successive year(2009—2010) in Daxing station in north china plain,of which,the measured date in 2010 was used to calibrate the crop parameters,and the other was used to test it.Then the OTA method was adopted to analyze sensitivities of the model parameter.The validation results showed that the AquaCrop model could preferably simulate the yield,biomass and the dynamic changes of canopy cover and soil moisture of summer maize.The relative error of simulated yield and biomass is 0%～15.6%.For simulated the process of canopy cover and soil moisture,the minimum correlation coefficient of determination were 0.657,0.959,the maximum of root mean square error 5.837%,1.873 m3/m3 and the minimum model efficiency was 0.670,0.956 respectively.The results of the sensitivity analysis showed that the day to CCx,the start date of canopy senescence,field capacity,wilting moisture content,initial moisture content among all of model parameters had the most significant influence on the simulation result,the sensitivity degree was 0.161 4～0.398 2.It marked the good applicability and the broad development prospects of AquaCrop model in this area.
