Traditional medical external fixation material represented by gypsum is brittle, heavy and prone to adverse reactions, clinical effect is not ideal. The pine wood fiber particles (size for 10 ~ 40 mesh) and polycaprolactone (PCL) are used to prepare a new kind of wood-plastic polycaprolactone composites (WPC) by the blending method. The experimental results show that the increase of PCL mass ratio can enhance the material strength and flexibility, especially the match force between the pine wood fiber particles. Meanwhile, when the mass ratio of PCL reached 65%, this enhancement effect significantly diminished; after the mass ratio of PCL reached 70%, the phenomenon of material mechanics performance decline. In this paper, the prepared WPC, which can soften under temperature 50°Cand repetitively finalize the design, have good mechanical properties, low-temperature thermoplastic and environment protection.

Using radio frequency magnetron sputtering deposition deposit ZnO films on SiO2glass, and prepare vertical structure ZnO-based thin film transistor. By means of measurement, obtain the static output characteristics, the output current can achieve the order of milliampere, get the transfer characteristics of ZnO TFTs; transconductance which get the largest value gm=0.0061S when source-drain voltage VDS=3V, source-gate VGS=0.4V; output resistance and voltage amplification coefficient, the smallest voltage amplification factor is μ=1.16056,still have voltage amplification effect.

Thin-film diode structure is MgAl/PbPc/Cu if lead phthalocyanine is taken as organic semiconductor gas-sensing material with methods such as vacuum thermal evaporation or magnetron sputtering. Use Keithley 4200 semiconductor instrument and Gas-sensing measurement system to analyze gas-sensing characteristic of Schottky diode device, the sensitive degree of NO2 with different density can be compared through theoretical analysis of measured current and voltage data. The measurement result shows: when the device is placed in 10ppm NO2 environment, after 74 minutes, forward current is decreased by 65 times, the corresponding MgAl/PbPc Schottky barrier height rises about 20meV. Reversed current of the device is 4 times larger because the increase of minority carrier electron number in PbPc thin-film is being absorbed by NO2.

With the method of vacuum dc sputtering and vacuum evaporation,the green light double organic light-emitting devices (OLED) of ITO/CuPc/Alq3 / Al structure were prepared, the electrical characteristics and electroluminescent properties of the device were measured. Devices show good luminous performance, light intensity reaches 600000 cps, when the wavelength of luminescence spectrum is 510 nm, luminance is 2641I/a.u.

Inductively coupled plasma mass spectrometry (ICP-MS) was used to determine the concentrations of rare earth elements and yttrium (REY) in coal and associated rock samples from the Guanbanwusu Mine, Jungar Coalfield, Northern China. The Guanbanwusu coals have a similar vitrinite reflectance and sulfur content, and a slightly higher ash yield. The concentration of REY (from La to Lu plus Y) in the 6 coal of the Guanbanwusu Mine varies from 72 μg/g to 396 μg/g and averages 186 μg/g, higher than that in normal Chinese coal (136 μg/g) and much higher than that in average world hard coals. The H-type distribution patterns in the No. 6 coal (W9-2 and W9-9) were probably caused by stronger water influences than those in the other coalfield. The coal bench (W2 and W9) with L-type is because terrigenous input influence.

Pipe failure accidents (bulging, bursting) are frequent in thermal power plants, and severely influence the safe and economic running. The authors analyzed the possible causes and features of low-temperature superheater pipe bulging. Taking the low-temperature superheater pipe bulging accident in a power plant for an example, the authors conducted macroscopic topography analysis, running environment analysis, metallurgical analysis, chemical composition analysis and strength analysis of the bulged pipe. Paper’conclusion was that the cause of low-temperature superheater pipe bulging wasn’t superheating, and the cause of bulging was flame straightening of the pipe during installation. The paper's innovation is material and dynamics analysis of the accident cause.
