To solve the deficiency of steel anchor blot in corrosion resistance and flaw of GFRP anchor bolt in fracture resistance, our research group develops a new composite anchor bolt made of steel strands wrapped up with compound fiber resin. To improve the cohesion performance of the composite anchor...
The quaternary In/sub 0.52/(Al/sub x/Ga/sub 1-x/)/sub 0.48/As compound on InP substrates is an important material for use in optoelectronic and microwave devices. We systematically investigated the electrical properties of quaternary In/sub 0.52/(Al/sub x/Ga/sub 1-x/)/sub 0.48/As layer...
A compound refractive lens (CRL), consisting of a series of N closely spaced lens elements each of which contributes a small fraction of the total focusing, can be used to focus x rays or neutrons. The thickness of a CRL can be comparable to its focal length, whereupon a thick-lens anal...

The onset of inhibition is usually rapid following a single administration of the inhibitory compound. However, as will be discussed later, some types of inhibition are not manifested rapidly. On the other hand, enzyme induction, which results in an increase in the total amount of an enzyme ...
Compound interest reveals the value growth characteristics of human wealth creation. The foundation of supporting compound interest which is the most powerful force in the universe is the enormous creativity of human beings and the growing productive forces.A、正确B、错误 相关知识点: 试题来源: 解...
A linear correlation was found between the molecular indexes in compost and the microbial groups in soil, thereby suggesting that the molecular composition of compost strictly controls the development and abundance of soil microbial communities. These findings highlight the importance of controlling the ...
In this study, methanol was pre-mixed in the intake manifold of a diesel engine,and the combustion characteristics and emissions of the compound combustion were investigated. The results show that combustion start point of the compound combustion is later than that of the diesel, but the combustio...
A new method is disclosed for treating a concrete surface to be used in contact with sea water to prevent fouling of the surface, which comprises the steps of: (a) fluating the concrete surface with an aqueous solution of a compound sele... DS Moraru - US 被引量: 39发表: 1981年 Met...
With the quick development of science and technology, especially after the Entry to WTO, China has globalization of science and technology. As a result, we are in great need of transla-tion of English for Science and Technology. This paper, based on the summary of the characteristics of Engli...
