Research on large size direct shear test for geocell reinforced soil;

The manufacturing technology is critical for the wide applications of structural ceramics especially for those of large size and special shapes.

The crystal growth technique of large size Y:PbWO4 crystal by the Bridgman method was discussed.

The plane accuracy research of 3D control network based on laser tracker in large-scale space;

More precision measuring instruments have been developed to meet the globalization and informatization of large-scale industrial manufactures.

By means of large-scale fire model test,the relationship among throttling effect,ventilation speed and fire\'s scale has been deeply studied.

This thesis deals with some issues of materials science and technology in Project "applied research of large dimension concrete pavement slab at Zhengzhou airforce airdrome", one of the Key Technological Research and Development Programs of the Tenth Five-Year Plan for Airforce.

To accomplish the task of measuring the roundness of the large dimension andheavy workpieces, an overall design project of measuring large dimension bearing ringhas been developed, by using modular overall structure.

This paper introduces a novel precision measuring technology for large dimensions using two longitudinal modes He-Ne laser withthermal frequency stabilization as light source .

Laser vision-based measurement of large-size part straightness;

Using this apparatus shear strength of large-size fissured loess samples formed in different time are tested with different loading methods.

Adenosine triphosphate (ATP) is an important high-energy compound widely used in clinical treatment,and,a novel separation method of using large-size anion-exchange supermacroporous cryogel was developed in this paper to isolate the ATP directly from crude fermentation broth of Saccharomyces cerevisiae.

The results indicate that there is a strong relation between the characteristics of previous particle boundary and oxygen content,when the oxygen contentis below 40 ppm,previous particle boundary is constitutded of big size γ′ mostly,when the oxygen is beyond 70 ppm,previous particle boundary is constituted of MC carbide mostly.
