An Agilent 34972A Data Collector was used to automatically record the temperature every 30 s.
To run the simulation, the models were designed for an ideal-load HVAC system, and the weather file, as an input, was downloaded from the International Weather for Energy Calculations data for Guangzhou.
According to the experimental data, the PCMT cell and ceramic tile cell had different heating/rising rates, and the heating/rising rate of PCMT was lower than that of the ceramic tile during the heating/rising process.
The data onto Table 2 show that the PCMT possesses the ability to effectively delay the heat transfer.

Geological Characteristics and Waterflooding Strategy for Yuanshi Low Permeability Sandstone Reservoir Wei Zhu 1, a, Zijian Cao 1,b 1 Hunan University of Science and Technology, Xiangtan, Hunan 411201, China aEmail:zhuweizq@163.com bEmail:781031706@qq.com Keywords: low permeability sandstone reservoir; waterflooding; reservoir sensitivity; solid-liquid coupling effect Abstract Core test data from 10 wells indicate that the sandstone reservoir in Yuanshi oilfield is characterized by low permeability, thin pore throat, high clay mineral content, and strong sensitivity, which are likely to cause reservoir damage and affect development result.
When incompatible injected water meets reservoir clay minerals, the clay minerals will swell, causing permeability reduction, therefore water-sensitive evaluation is important in sensitivity investigation for waterflood oilfields.

Production test data indicate that the threshold pressure gradient at present is 0.5-0.7MPa/m in this oilfield.

They do readily undergo oxidation or reduction than naphthalene.
No charge transfer accompanied the reduction process, only absorption.
The kinetic evaluation of voltammetric data of the cyclic voltammograms at different scan rates for PDMAASA and PDMA-PSA is presented in Figs. 6 and 7 respectively.
The Randles-Sevcik equation of analysis of voltammetric data {Ip /  1/2 = 2.686 x 105 n3/2 A * De 1/2 } was used to determine the rate of charge transport coefficient (De) along the different polymer chain [29].
From the Nyquist plot (Fig. 8) for data recorded at potentials of -300 to 500 mV in steps of 100 mV, least resistances were recorded at the region corresponding to the transition from the leucoemeraldine to the emeraldine state of polyanilines.

Abstract.Along with the raising of the train speed, aerodynamic noise of the high-speed train is generated more and more significantly and their reduction has become one of the key factors to control noise of the high-speed train.
In China, the field test of high-speed train noise is carried out through using the data acquisition and analysis system of multi-channel microphone array for high-speed railway noise[5], the major sound sources of the emitting noise from 350km/h high-speed train are the aerodynamic noise from the bogie, recess of the pantograph, and the inter-coach spacing.
Fluctuating pressure is extracted from the original data, through high filtering, those data is converted from the time domain signal to frequency domain signal by fast Fourier transform, and the dimensionless power spectrum is translated to the true scale of the flow field.

The visualized blue staining was recorded by Sony camera. 2.6 Statistical analysis All the tests were done three times and the data were averaged.
Duncan’s multiple Ttest (p<0.05) was used to evaluate significant difference in different mean values. 3.Results and Discussion 3.1 SDS-polyacrylamide gel electrophoresis (SDS-PAGE) According to the previous results (data not shown), the optimum factors include fermentation period (48 h), water volume (50 ml), autoclave period (40 min) and (NH4)2SO4 quantity (2.0 g).
The partial digestion of large peptides in FPNM is attributed to proteases secreted by Bacillus subtilis AS1.260 (data not shown).
We have carried on the relation between the structure and the allergens of FPNM (data not shown). 3.2.Analysis of total amino acids by HPLC Table 2 presents the protein concentration (nitrogen ×6.25) and amino acid profile of PNM and FPNM.

Due to the inconsistency of the data, as well as the importance of ensuring stable quality of high-speed steel, the effect of copper content on the physical and technological properties of serially produced high-speed steel R6M5 (C – 0.87, W – 6.20, Mo – 5.00, Cr – 4.00, V – 1.70,Ni – 0.09, and Co – 0.10 wt.%) was investigated [1].
The strip-casting specimens were cold rolled to 70% reduction and then annealed isothermally at 600, 650, and 700°C for different times.
However, at 450°C, the presence of ~2 wt.% Cu leads to lower strength and a significant reduction in ductility.
Elongation and reduction before rupture fall to 5–6%, compared to similar copper-free steel.
The given structural data correlate well with the mechanical characteristics of these steels.
