The results show that , for flexural - tensile fatigue test and shear fatigue test , the two kinds of structure of common asphalt concrete with strata stress absorbed layer and glass fiber grating had good ability to resist reflection cracking , while the effect of paving asphalt concrete directly on cement concrete slab was worse 结果表明，对于弯拉型疲劳试验和剪切型疲劳试验，普通沥青混凝土下面铺设strata应力吸收层、玻璃纤维格栅2种结构都具有良好的抗反射裂缝的能力，而在水泥混凝土面板上直接加铺沥青混凝土类结构的效果最差。
The paper did scrupulous discussion and investigation on the interaction between electron beam and standing wave field in the gyroklystron , which is typical in the electron cyclotron maser which action rf system is resonant cavity . the main works of this dissertation are listed as following : first , solving field in absorbing material and field matching method were used to derive the dispersion equation in waveguides and field matching formulas of hybrid modes in an abrupt cavity with absorber . based on the theoretical analysis , numerical simulations of the cavities in gyroklystron were done 主要工作有:一、采用吸收介质分区求解及场匹配的方法推导出含有吸收层的色散方程,单侧加入吸收介质及两侧均加入吸收介质两种突变结构混合模场的匹配方程,在理论分析的基础上,通过相关的模拟软件,建立了回旋速调管介质加载中间腔的计算模型,对回旋速调管中间腔进行了数值模拟,并给出了主要的计算结果。
Owing to its optoelectronic and chemical properties , cdte is an ideal absorber material for high - efficiency , low - cost polycrystalline thin film . the thesis has investigated the structure , figure and optoelectronic characteristics of cdte polycrystalline thin films , the performance of doped cdte , and the influence of their deposition and anneal process Cdte具有良好的光电学性质和化学性质,因此成为制备高效率、低成本的多晶薄膜太阳电池理想的吸收层材料。本文针对cdte薄膜,研究了其制备工艺、掺杂和后处理条件对薄膜结构、形貌和光电学性质的影响。
