  摘要：

  When milled together with bismuth shots, nitroarenes are readily converted to azoxy- and/or azoarenes depending on substrates and conditions employed. Simple extraction with organic solvent followed by evaporation of the resulting dark pasty solid gave the product in good yield.

  A LCD device element of frequency modulation mode enables high speed on and off control of an electro-optical response by switching the frequency of applied electric field. The LCD device element is capable of changing a frequency modulation range freely. The LCD device element has conductive layers between two parallel substrates; liquid crystal (LC) alignment layers with pre-tilt angle on the conductive layers; and a LC layer between the two liquid crystal alignment layers. LC soluble particles nanoparticles composing a core and a liquid crystal molecules or like molecules on its periphery), are in the LC layer. A control circuit applies voltage while modulating frequency on the conductive layer for varying light transmittance of the LC layer. Under a constant voltage, an electro-optical response is turned on by switching the frequency from low to high frequency and is turned off by switching the frequency from high to low frequency. The electro-optical response is varied also by varying voltage.

  频率调制模式的液晶显示设备元件可通过切换外加电场的频率来高速控制电光响应的开和关。液晶装置元件能够自由改变频率调制范围。液晶显示器件元件在两个平行基板之间具有导电层；导电层上具有预倾斜角的液晶排列层；以及两个液晶排列层之间的液晶层。液晶层中有由核心和液晶分子（或其外围的类似分子）组成的液晶可溶颗粒纳米粒子。控制电路在调节导电层频率的同时施加电压，以改变液晶层的透光率。在恒定的电压下，通过将频率从低频切换到高频来开启电光响应，通过将频率从高频切换到低频来关闭电光响应。电光响应也可通过改变电压而变化。
