In this paper, the melt blending method was used to prepare isotactic polypropylene (iPP) samples. The nucleating agents N, N'-dicyclohexyl-2,6-naphthalenedicarboxamide (TMB-5) was chosen to induce the β-crystal. The quenching, 130ºC isothermal crystallization, natural cooling molding processes were used to control α- and / or β-crystals in the iPP samples. The crystalline modifications and crystallinity...
Smart Grids technology is emphasized a lot in the future power system worldwide. Nowadays, the widely used Automatic Meter Reading (AMR) technology in Finland makes it possible to collect customers' hourly load measurements and to use data analysis methods for customer clustering and load prediction purposes. This paper addresses the detection of possible changes in customers' behavior. This could...
The temperature and moisture of single soil layer is difficult to represent the real growth environment around crop root. The measurement of temperature and moisture in multilayer and multipoint soil is easy to know water demand around crop root during its growth period deeply and accurately. It also can improve the water utilization coefficient and achieve basic data for the research on soil water...
Transparent and conductive microcrystalline silicon carbide (μc-SiC:H) thin films are an excellent window layer for thin film solar cells. For amorphous silicon based solar cells, p-type conductive μc-SiC:H window layers were deposited by the hot-wire chemical vapor deposition (HWCVD) technique. Monomethylsilane (MMS) highly diluted in hydrogen was used as the SiC source in favor of SiC deposition...
An integrated five-transistor/one-capacitor approach for realizing a a-Si:H thin-film transistor (TFT) gate driver operating in multiphase-clock mode is proposed and investigated. The driver needs only one large-size TFT and one small-size storage capacitor. The performance and function of the proposed driver are verified experimentally. The dependence of the performance on the device size is studied...
Artemisinin is difficult to formulate for parenteral administration because of its low aqueous solubility and Cremophor EL, the excipient used for its formulation, has been shown to cause serious side effects. This study reports the preparation method and properties of artemisinin lipid emulsion for parenteral administration. High-pressure homogenization was used to prepare artemisinin lipid emulsion...
In the paper the temperature field distribution in a urban distribution substation in Chongqing was calculated firstly. According to the parameters of the distribution substation and apparatuses in it, equivalent model was setup and method to calculate the boundary conditions for the temperature field is presented. Then factors influencing the distribution of temperature field in the distribution...
In view of the low speed, the heavy load, reversing, the frequently brake, the intense impact characteristics of AOD furnace tilting system, The double closed-loop with feedforward is used. Position regulator and speed regulator use PID algorithm. And the speed loop is designed, based on vector control. This control system was simulated by MATLAB Simulink software. The simulation result showed: Adjustment...
Chemical treatment of nisin fermentation wastewater (NFW) by Fenton oxidation (FO) process was studied. The influences of H2O2/COD ratio (w/w), Fe2+/H2O2 molar ratio, pH, temperature and reaction time were experimentally studied in a batch reactor. The optimal operating conditions for Fenton process were found to be at H2O2CVCOD ratio (w/w) of 2.0, Fe2+/H2O2 molar ratio of 0.15, pH of 3.5, temperature...
The effect of the ZnO homo-buffer layer on the structural, optical and electrical properties of the Sol-gel ZnO films was systematically investigated. The XRD and SEM results show that the homo-buffer layer can improve the degree of the preferential c-axis orientation (the best Lotering orientation factor (F) can reach 0.915), the grain size and the surface morphology of thereon ZnO films. A narrower...
The accuracy and stability of temperature in water tank of viscometer is one of the key factors of fluid viscosity measurement. An improved fuzzy control (IFC) method with PWM control for water tank temperature is proposed, which combines basic fuzzy control, improved Bang-Bang control with human-simulated intelligent control (HSIC), and is implemented by DSP, When the temperature error e between...
Nowadays, the methods of UHV system discharge detection are often by infrared imaging system, UV-C imaging system, etc. But none of them can measure the discharge degree of electric equipment quantitatively. As to the high dielectric level of the UHV system, the long distance from ground exists; especially in detecting the discharge of the electrical equipments on the UHV line tower, the detector...
