Published: November 2012

Effect of nitrogen, phosphorus and cooperation application on grain yield and qualities of high starch maize Zhengdan 18 was studied. Six different fertilization treatments based on the random-plot experiment. The results indicated that N fertilizer significantly increased yield, as compared with the non-fertilizer treatment, the yield with the combined application of N and P fertilizers was higher than that of maize with single N treatment, the yield with the combined application of N P and K fertilizers was superior to that of maize with the combined application of N and P fertilizers. The yield was increased with the increase of the fertilization amount of the combined application of N, P and K, but there was not the direct proportion between yield and fertilization amount in the growth period, obeying the reward descending rule. The number of grains of ear was important for seed yield. The experiments showed the contents of starch, lipid and protein were increased along with the increase of N fertilization amount. The content of starch was increased in the early stage and reduced in the late stage of postulation, At the same time, The contents of lipid and starch were not increased along with the increase of phosphorus fertilizer, The same is that the contents of lipid with the combined application of N, P and k fertilizers were higher than that of the combined application of N and P fertilizers, the accumulation of lipid was increased, while the accumulation of starch and protein were not increased with the increase of K fertilizers. The contents of protein, starch and lipid were higher in the early stage than that in the late stage of postulation with the low-fertilizer treatment. The accumulation of starch was increased with the increase of the amount of the combined application of N, P and k fertilizers, the content of protein and lipid were increased in its early growth stage, while its content was not increased in the late growth period. Considering for the economic performance and the balanced principle for the supply and demand of applying fertilizer, currently the best applying fertilizer treatment is: N: 225kg/hm2, P2O5 :112.5kg/hm2.

When MIMO is added in design of satellite signal transmission, it can increase channel capacity and reduce BER multiply. This paper introduced MIMO into satellite monitoring system, studied three kinds of QOSTBC on the mathematical model. Paper also analysed process of transmission for hydrology information and illustrated figures of BER for three QOSTBC. The results show that design of satellite monitoring system using MIMO has a lower BER than using SISO and the BER of rotated QOSTBC is less than other QOSTBC. The original in this paper is that it combines hydrology satellite monitoring with MIMO. It gives theoretical method for hydrology monitoring and transmission

Published: November 2012

Molecular modeling and dynamics simulations were used to generate equation of state properties of amorphous cellulose with the reactive force field ReaxFF which has been extensively parameterized and validated for hydrocarbon in a previous communication. Obtaining specific volume as a function of temperature for amorphous cellulose, the change in slope of the specific volume vs. temperature curves can be used to locate glass transition temperatures (Tg) reliably. With the results, there was reasonable agreement between experimental results and values of density and Tg obtained from the simulations. In addition, the suitable ReaxFF time step was investigated to help conserve the total energy of the system. The results show that the glass transition temperature can be used to verify the equilibration of the amorphous cellulose and to provide insight into the further deformation simulations.
