Through analyzing the deflecting action of stress on the spin magnetic moment of ferromagnetic material, the strain was connected with the magnetizability. The theoretical formula in accord with the experimental data law was obtained and the reason why the stress σ brings on the induction EMF ε changing was expressed.
In the device,the lateral injection effect is suppressed,that is,the injection will be concentrated in the middle of the emitter area and the minority carriers in the neutral base area is double deflected, thus climinating the lateral reactive current.
Influence of aggregate size on fracture properties of concrete was studied by means of AE technique,and three dimensional acoustic emisssion technique was applied to observe the phase of the fracture process of concrete. The results show that the fracture energy increases with increasing the maximum aggregate size. Moreover,there is a good corresponding relationship between AE counts and fracture energy.
The improvement of the mechanical properties of materials was mainly caused by the following factors:one was the conversion of carbon fibres into SiC fibres,and the another was the volume expansion during CB-template-to-cellular SiC conversion,which inhibited the initiation and propagation of cracks and made cracks deflect.
A lateral magnetotransistor made with buried p-layer CMOS technology is described. The device is constructed with a double base, double collector npn transistor. In the device,the lateral injection effect is suppressed,that is,the injection will be concentrated in the middle of the emitter area and the minority carriers in the neutral base area is double deflected, thus climinating the lateral reactive current. The buried p-layer is to eliminate the vertical reactive current. The device has an excellent linear...

It was reported that there is a sudden change on light transthessivity of crystal mag ma at its saturationtemperature. In order to study the mechanism, the phenomenon of the sudden change on crystal diffusion layer nearby the syrup saturation temperature was record ed with the holographic interferometry. The bend of light beam on the interface of the crystal particle andits diffusionlayer was analyzed accordance with the diffraction law of light trans drissivity of magma does not decreased until the supersaturated...

The bend of light beam on the interface of the crystal particle andits diffusionlayer was analyzed accordance with the diffraction law of light trans drissivity of magma does not decreased until the supersaturated magma was heated,and the alter of diffusion layer plays an important part in this sudden change of light transmissivity.
Mica_containing glass-ceramics before and after hot_pressing treatment were investigated by X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). It is found that mica crystals randomly dispersed in the glass matrix before hot_pressing orientate preferentially after hot_pressing treatment,combining with the viscous flow of the residual glass phase. After hot_pressing treatment,both fracture toughness and bending strength constantly increase with the crystallization time and hot_pressing...
Mica_containing glass-ceramics before and after hot_pressing treatment were investigated by X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). It is found that mica crystals randomly dispersed in the glass matrix before hot_pressing orientate preferentially after hot_pressing treatment,combining with the viscous flow of the residual glass phase. After hot_pressing treatment,both fracture toughness and bending strength constantly increase with the crystallization time and hot_pressing deformation. This is attributed to the variation of the microstructure, i.e., mica crystals preferentially oriente in the glass matrix,which effectively deflect the crack propagation along the direction of hot_pressing.
