Using five kinds of satellite-derived sea surface temperature (SST) from infrared radiometers (AVHRR, MODIS/Aqua, MODIS/Terra) and microwave radiometers (TMI, AMSR), a set of high-quality, cloud-free, high-resolution (1/20°) merged SST product was generated through an optimum interpolation scheme. The area of merged SST product (OISST) [0–42°N, 95–150°E] covers the whole China Sea as well as the western...
Yuyuan area of Linfen city is located in Linfen basin of Shanxi province. It is very complex that the constitutive structures is in the area because of the effect of Lvliangshan swell and Taihangshan swell, etc. Combined research of CSIRO in-situ stress measurement and theory of geomechnics is carried on in this paper. Values and directions of stresses are obtained and the relationships between the...
Four scenes of Landsat TM images which were obtained on September 15th, 1988; September 11th, 1998; September 1st, 2006 and August 24th, 2009 separately were utilized, the corresponding surface temperature of Huayan new city in Chongqing were retrieved with mono-window algorithm carried out by Qin Zhihao. The retrieved results show that during the 21 years from 1988 to 2009, high temperature regions...
Balcony greening have the ecological effects on reducing temperature and increasing humidity,purifying air and beautifying environment etc. Combined the experiments with simulation, by figuring out the potency of reducing temperature and increasing humidity of balcony greening on indoor thermal environment, the correctness of the model was verified. The results show that the temperature of the greening...
[Objective] This paper focuses on analyzing the energy resources and precipitation trends to the context of global warming in the western Liaoning Province in recent 60 years, where located in the northern hemisphere. Provide the basis study for the adjustment of agricultural structure and full use of energy resources. [Method] Use meteorological data of three cities in western Liaoning Province during...
Based on the SPOT VEGETATION NDVI data, the spatial-temporal variations of vegetation cover in Hexi region of Gansu province were analyzed by using the MVC (Maximum Value Composites) method and the linear regression analysis during 1999 to 2009, the NDVI change trends and characteristics of different land use types were extracted. According to the results, during the last 11 years, the vegetation...
Poly methyl methacrylate-co-glycidyl methacrylate copolymers (PMMA-GMA) was synthesized by bulk polymerization. The copolymers were blended with polylactide (PLA) in Haake rheometer at different weight ratio from 0% to 15% as chain extender and modifier. The properties of neat polylactide(PLA) and modified PLA were characterized using gel permeation chromatography, differential scanning calorimetry,...
Fe2O3 powders with highly crystalline have been synthesized by a sol-gel auto combustion synthesis method accompanying thermal process. The phase structures, morphologies of Fe2O3 have been characterized by x-ray powder diffraction (XRD) and scanning electron microscopy (SEM) equipped with energy dispersive x-ray spectrometer (EDX). The results show that complete and highly crystalline nature magnetite...
In this paper, the natural echinocystic was modified using succinic anhydride acid. The optimum conditions for modification are following: reaction solvent is pyridine, reaction temperature is 95°C, reaction time is 8 hours. The polarity of the product was measured by High Performance Liquid Chromatography, and the structure was confirmed by IR and MS. The results show that the polarity of product...
The cold flow properties of waste oil biodiesel (WME) were studied by gas chromatography-mass spectrometry (GC-MS), multifunctional low temperature tester, differential scanning calorimetry (DSC) and solution crystallization theory. Three approaches for reducing cold filter plugging point (CFPP) of WME were investigated: crystallization fractionation, blending with winter petrodiesel and treating...
In this paper, a silicate monitor was researched and produced according to the chemiluminescence principle. Measuring and controlling were carried out by computer. The monitor has more advantages than others in measuring principle, responding time, hydraulic equipment, operating method and so on. It is well instrument for monitoring silicate in water treatment processes.
This paper presents the retrieval of Sea Surface Temperature (SST) from the measurements acquired by the InfraRed Atmospheric Sounder (IRAS) onboard the Chinese second generation polar-orbiting meteorological satellite FengYun 3A (FY-3A). First, the intercalibration of IRAS/FY-3A channels 8 and 9 with AIRS/Aqua channels in July 2008 over the North Pole region was implemented using the High Spectral...
Based on one 160m PC bridge project, the field measurement and finite element analysis of the hydration temperature of cast-in-situ box girder on top of pier have been completed. The distrabution of the hydration temperature fields and the rule of the temperature changing with time have been sumed up in this paper. The factors which affect the hydration temperature of cast-in-situ box girder on top...
The cooling metering of fan-coil units plays a key role on the charging of cooling supplying in the central air conditioning systems, which improves the energy efficiency of systems and decreases the controversies between the owner and the user. In order to achieve both of accuracy and affordability on metering, a new metering method is proposed by analyzing the principle and application of water-side...
In this study, the land surface temperature (LST) from Moderate Resolution Imaging Spectroradiometer (MODIS) sensor which was chosen as one scalar temperature directly modifying light use efficiency (LUE), together with the 8-day composited MODIS data and the site measurements of photosynthetically active radiation (PAR) of a subtropical evergreen coniferous forest ecosystem in southern China during...
In-situ stress is a natural stress existing in earth crust and isn't disturbed yet by mining, which is the fundamental force to cause deformation and failure in mining and other underground works. To study the stability of surrounding rock in the 8th mine of Pingmei group, overcoring technique with complete temperature compensation technique and improved hollow inclusion strain devices were used in...
The tributyltin chloride and Al-MCM-41 containing silicon(SiAlM) were heated at 180°C for 5 h under stirring conditions in nitrogen atmosphere, and a production of R3Sn-O-Si-Al-MCM-41 (R3SnSiAlM) was got. The composition, structure and surface physical and chemical properties of the samples were characterized by elemental analysis (EDS), fourier transform infrared spectroscopy (FTIR), N2 adsorption-desorption,...
A series of siloxane Gemini surfactants, a, b, c and their acrylates, A, B and C, were synthesized via poly (ethylene oxide)(PEO)(MW=200, 600,1000) and polydimethylsiloxane as the main starting materials. Gemini A, B and C were adopted as the grafting monomers of linear low density polyethylene (LLDPE), and grafting reaction was carried out by melt reactive extrusion procedure. Their surface properties...
Hydration heat in large concrete of box girder is always a difficult problem in bridge construction, if misconduct, the temperature crack will be formed easily.
