呜声 meaning in English
wooliness
Examples
- The above outcomes show that nxiits is most important in controlling the tone varieties and the numbers of the harmonic parts and the course of the vocal control maybe a process of alternative replacing
Nxllts可能在控制其鸣声的音调变化以及影响其呜声的谐波数量上起到一定的作用，其控制区发声的过程很可能具有交替更换的特性。 - The bird is extremely versatile in its feeding . they can be seen in hillside , woodland and places with at least some trees . their voice is the typical call of the crow , only deeper and more resonant
大咀乌鸦非常杂食，偏好山区、树林和有疏落树木的地方，呜声是典型的乌鸦叫声，只是较低沉和响亮，而且和所有鸦类一样，大胆而聪明。 - The second male vibration signal ( smvs ) could not only stimulate female and male to give their love sound , but also gave rise to male unease and competition . male giving smvs was more competitive . smvs was often heard when many males congregated together
时域特征分析知，褐飞虱雌、雄虫求偶呜声信号的时域特性个体间差异较大，个体内不同次呜叫也有差异，但小于个体间的差异。 - Female courtship signal of the brown planthopper was made of many continuous regular pulses and male ' s signal was made of similar syllabics and had two types with different time domain characteristics . second male vibrational signal differed from male courtship signal with wide spectrum range and regular syllabics frequency . time domain characteristics of signals in different individuals even the same individual were different
频域特征分析知，褐飞虱雌虫求偶呜声信号的频域特性较稳定，个体内比个体间差异小；雄虫求偶呜声信号s 、 e片段频谱范围较宽，但主振频率比较接近，差异不显著； m片段频带较窄，主振频率mvf略小于s 、 e片段，变异较小； m片段脉冲重复频率prf为幻 - Synthesized signals with different pulse repetition frequencies ( prf ) and main vibration frequencies ( mvf ) were presented to the brown planthopper . the results showed that prf was a sensitive and important signal characteristic in mating choice . the prf and mvf sensitive ranges of male signals were 70 ~ 90hz , 200 ~ 1700hz separately , and of female signals were about 22hz , 100 ~ 300hz separately
雄虫敏感的prf范围在22hz左右，雌虫敏感的paf范围为70 90hz ，这与实际的雌、雄虫求偶鸣声的pm变化范围是一致的；雌、雄虫能对mvf变化范围较大的信号敏感，雄虫敏感的mvf范围为100 300hz ，与雌虫求偶呜声的mvf变化范围是一致的，而雌虫敏感的mvf范围为200 1700hz ，要比实际的雄虫求偶鸣声的mvf变化范围大的多。
