It is shown that beams of reinforced average strain distributing accord with flat section assume; The method of strengthening intension of concrete structure with reinforced materials is a feasible way. The strength of beam can be increased with the number of reinforcement materials be added; The strength of beam is affected by percentage of flexural reinforcement and the compound proportion and fashion of reinforcement materials and the number of reinforcement materials; The capability of bend and stretch and price of inner hybrid fiber is better than sole fiber and exterior hybrid fiber.

This paper analyses mechanics property of horizontal press winding adopted on warping machine, develops the law of warp beam pressure and puts forward the way to reduce the motion between the roller and warp beam.

分析了整經(jīng)機水平軌道式加壓卷繞機構(gòu)的力學(xué)特性久久机热免费，通過計算得出了經(jīng)軸正壓力的變化規(guī)律国产aaaa黄片，提出了降低滾筒與經(jīng)軸間壓力最大波動幅度的措施。

If a particular color or wavelength of light hits the ytterbium when it is in the excited state this light will be a aplined, generating a carbon copy of the original light. In this way a very lower perfect beam can be amplified many times to produce high power beam that are nearly perfect and are therefore very focusable.

Through systematic study, it is found that the ion dose is another important parameter in Ion Beam Manipulation and it has significant influence on the strutrual phase transition. If the dose is precisely controlled, the structural phase transition could be traced under a quasi-continuous way. Consequently, many new phenomena have been discovered by Ion Beam Manipulation.
