The results showed that the frequency of germination were able to be increased by keeping seed vessel, culturing seeds with radicle up and pre-treating seeds in 5.0mg/L GA3 solution for 12h. The frequency of explant-browning was reduced by adding AC 0.5mg/L to induction media and the vigor of plantlets was promoted by the AC-adding. The propagating coefficient could be improved and the frequency of bud-vitrifration increased by adding 150mg/L coconut water.

从3000年来4.7级以上的(ji2 yi3 shang4 de0)历史地震的史料记录频度看（图5），宋朝以前的绝大部分时间都在（2次/10年）以下；宋朝出现了印刷术，记录频度增到（3次/ 10年）以上；1900年后现代地震仪问世，记录频度达到（100-1000次/10年）的高水平。

A silent communications system in which nonaural carriers, in the very low or very high audio-frequency range or in the adjacent ultrasonic frequency spectrum are amplitude- or frequency-modulated with the desired intelligence and propagated acoustically or vibrationally, for inducement into the brain, typically through the use of loudspeakers, earphones, or piezoelectric transducers.

一个沉默的联系是不承载听觉，在非常低或非常高音频范围里，或在邻近的超音速的频谱中，这是广阔的-或带有期望的智能并且传播声学的频率调节或振动，为了刺激大脑内部，典型的是通过利用扬声器，耳机，或压电式换能器。

We got the simple and high accurate eigenvalue equations and cutoff frequency formulae of all propagation modes. Second, to the optical fiber with homogeneous cladding, we defined the "permittivity ratio", and we got the simple and high accurate connection of cutoff frequency to the ratio. Third, to the fiber with inhomogeneous cladding, we analyzed the dispersive and power-frequency characteristics.
