The rising/fall rate of design flood graph is also the rising/fall rate of design H～Q curve,based on which the design H～Q curve can be determined.
探讨了水利工程设计时常采用一条所谓综合H~Q曲线存在的误区,H~Q和洪水一样,有设计洪水,就有相应的设计H~Q曲线,它是和设计洪水配套的,设计洪水过程线的涨落率,也是设计H~Q的涨落率,由此求设计H~Q曲线。
Based on the mobility fluctuation and carrier number fluctuation mechanisms and 1/f noise models of poly-Si conductive materials,the noise model of mobility fluctuation is revised.
在多晶硅导电材料的1/f噪声迁移率涨落、载流子数涨落机制和模型的基础上,修正了基于迁移率涨落机制的噪声模型。
