modulation property meaning in Chinese

调制性质

1 . firstly , the mathematical model of fiber pair with the factors of reflector shape and inclination is established . then , the numerical simulation is fulfilled , along with a series of rules of the influence on intensity modulation property caused by multimode fiber parameters , the factors of reflector shape and inclination
然后，采用数值仿真的方法系统地研究了多模光纤参数(包括光纤对轴间距、光纤芯径和光纤数值孔径) 、反射面倾斜因子以及形状因子对rim - fos强度调制特性的影响规律。
Compared with non - passerine , they appeared longer syllable length , higher basic frequency and more viable frequency ranges . though the amplitude modulation properties enhanced their vocal production , the type of syllable is still stable and less of variety . so the phrase consisted of syllables are comparatively few and changes of the tone are relatively less
且表现出很强的频率调制特性和特有的幅度调制特性，相对的音节时程比较长，基频较高且频率变化范围较大，所特有的幅度调制特性更增加了其控声的能力，但其音节的种类仍很单一，缺乏变化，由音节所组成的句型较少，音调变化幅度不大，因此，其叫声质量尽管较非鸣禽有所改善，但相对鸣禽而言却又远远不如。
