The properties of photochromic materials, such as their absorption spectrum, refractive index, dielectric constant, oxidation and reduction potentials, photoluminescence, dipole moment, and ionization potential (Ip), can be changed reversibly during the photochromic process.
Such diarylethene derivatives have been expected to have wide application in optical data storage and retrieval, rewritable optical memory and display, various sensors and switches, etc.

Figure 2 shows feature maps of stress sensitivity of different lithology (the permeability change curve above of hyperbolic, is during the process of compression, and the other curve below is the permeability curves for the decompression process), Table 2 shows the data of the experimental results of stress sensitivity.
During the process of confining pressure decreases, with a gradual reduction of the confining pressure, the permeability starts increasing, while the increased rate of penetration is always smaller than the decrease rate of the confining pressure.

From current experimental data, the reduction factor for impact performance can range from 0.95 to 0.7.

Observation and survey system: sub-macroscopic visual observation system, samplers, pressure sensors, data collecting system composed of thermocouples, thermographs and measuring instruments.

Hydrodynamic Performances Prediction of Ship Hull and Propeller with Rudder In order to verify the suitable of the hydrodynamics performance prediction method of ship hull and propeller with rudder, the paper studies one full form ship which has experimental data.
The rudder bulb has the following effect in general. (1) Reduction of rudder resistance by straightening effect of propeller flow field. (2) Decrease viscous loss after propeller cap

At pH 1.61 (the lowest pH of the influent liquor used in the case) the concentrations of free protons and HSO4- were calculated to be 25 and 14 mM respectively, i.e. sufficient for the reduction of ~20 mM sulfate.
In the case of the synthetic raffinate, sulfate concentrations in mine water at the site itself are well in excess of those used in the current experiments, so synthetic water used in the experiment was always acidified with sulfuric, rather than hydrochloric, acid, Data (Fig 2) show that more sulfate (up to 35 mM in total) was removed than with the synthetic Nochten water, though the efficiency of this in terms of electron donor usage was far lower.

The method in spatial is getting the information of the original image, a denoising algorithm based on pixel gray value of direct data operation, to obtain the desired results.Transform domain denoising is a kind of transformation to transform a class of information of image in spatial domain, then the transformed information processing, finally the processed information through the inverse transform backinto the spatial, the image space domain to achieve the purpose of removing noise.
In the spatial domain filtering algorithm in the past, the direct use of variance of noise image gray median or mean value as a threshold, smoothing the details of the image, reduction image quality.

Equivalent Static Wind Loads on low rise buildings Fanghui Li1, a, Ming Gu2,b and Shizhao Shen3,c 1 School of Architectural Engineering, Heilongjiang University, China 2 State Key Laboratory of Disaster Reduction in Civil Engineering, China 3School of Civil Engineering, Harbin Institute of Technology, China afhli_2000@163.com, bminggu@tongji.edu.cn, cszhshen@hit.edu.cn Keywords: equivalent static wind load, wind tunnel test, modal inertial force combination method.
The wind response and equivalent static wind load are calculated using the wind tunnel pressure data were measured substantially simultaneously in the B category of the wind field.

Under the promise of maintaining classification ability, it was given that decision-making and classification rule by knowledge reduction.
Recently, the rough set theory has been applied in many fields, such as machine learning, decision analysis, process control, pattern recognition and data mining.

However, SiO2 in slag would suppress reduction of MgO, CaO in slag by [Al]s in steel, which is not beneficial for transformation of the product of Al-deoxidation.
Results Owing to failed sampling at LF1-1, there’s no data for NO.1 heat at LF1 in figures below. 2.2.1.
