the strong confined concrete and weak confined concrete according to the confinement stiffness ratio βj or confinement ratio ξ.
本文通过不同增强纤维包裹的混凝土圆截面短柱的轴压试验,并结合国内外同类试验结果分析,认为纤维约束混凝土根据约束刚度比βj或约束比ξ的不同,可分为强、弱约束两种不同情况,分别讨论了它们在弹性、弹塑性及强化或退化不同阶段核心混凝土所处的状态和应力-应变曲线的特点,认为约束刚度比决定了强化或退化段的直线斜率,约束比决定了强约束混凝土的强度。

The asymmetrical fused-taper coupler is studied theoretically with weakly guiding and weakly coupling approximation in this paper, the analysis reveals that this kind of couplers have wavelength-flattened characteristics, and the degree of asymmetry can affect the splitting ratio directly.
在弱导和弱耦合近似下,对熔锥型非对称耦合器进行了理论计算与分析,理论分析表明:这种非对称耦合器具有波长响应平坦的特性,而且非对称程度的大小直接影响耦合器输出功率的分配(即分束比);通过在拉锥过程中控制组合波导的不同直径比,可以得到不同分束比的宽带耦合器。
