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
且表現出很強的頻率調制特性和特有的幅度調制特性，相對的音節時程比較長，基頻較高且頻率變化范圍較大，所特有的幅度調制特性更增加了其控聲的能力，但其音節的種類仍很單一，缺乏變化，由音節所組成的句型較少，音調變化幅度不大，因此，其叫聲質量盡管較非鳴禽有所改善，但相對鳴禽而言卻又遠遠不如。 -

Our results show that pmd induces pulse broadening randomly in high bit - rate optical fiber communications ; the synchronous amplitude modulation control may correct directly any position change of timing jitter and soliton interaction, so the transmission distance and pulse quality will increase further
研究結果表明對于高速率傳輸系統， pmd對脈沖的影響在時域上表現為脈沖形狀的展寬，這種展寬是隨機的；而同步幅度調制是在時域上，將發生形變的脈沖通過振幅調制，恢復原形，從而提高脈沖的傳輸性能。 -
The tests of e - o applications by our flux ktp has been realized, the results showed : optical waveguides fabricated by using an ion - exchange process, which have an exchange - ion concentration depth profile and refractive - index profile, is close to a complementary error - function distribution, optical homogeneity and device thermal stability is much better. amplitude modulation switch formed by our flux ktp has the contrast ratio of 150 : 1 and insert loss is 2. 5 % at 1064 nm. high quality optical pulse with 1 ns width was cut successfully by using an e - o modulator from a laser pulse with 50 ns width, this modulator had run for three years, and the crystal did n ' t blackened, it showed our low conductivity flux ktp can endure high modulation voltage for a very long time
