查询词典 sectional area

An aerosol spray device which is capable of imparting a unipolar charge by double layer charging and charge separation to liquid droplets of a composition sprayed therefrom has a spraying head in the form of an insert in an actuator, the spraying head having a bore through which liquid is expelled having an outlet, preferably with a tortuous periphery, having an L/a ratio of at least 8 (preferably at least 10) where L is the length of the periphery defining the bore outlet in mm and a is the cross-sectional area of the bore outlet in mm2 and the apparatus being constructed such that the droplets are expelled from the spraying head at a flow ratio of at least 0.4 (preferably at least 0.5) grams per second and have a charge to mass ratio of at least +/-1x10-4 C/kg.

本发明还提供了一种喷射装置，它能够通过双层充电和电荷分离而向要喷出的组合物液滴施加单一极性的电荷，该喷射装置具有一个喷头，该喷头制成为致动器中的插入件的形式，喷头具有一个孔腔，液体能够通过该孔腔从装置中排出，该孔腔具有一出口，该出口最好具有曲线周边，并且L/a比率至少为8，其中L是以mm为单位的确定孔腔出口的周长，a是以mm2为单位的孔腔出口的横截面积，该装置构造成使得液滴在至少每秒0.5克的流动速率以及具有至少＋／－1×100C/kg的电荷／质量比的状态下从喷头排出。

The analysis results show that the energy loss is related with the lenght and the flow quantity of connective pipe, and cross sectional area ratio between the pipe and hydraulic accumulator, which will be helpful for the design and engineering installation of the hydraulic accumulator.

分析表明，液压蓄能器的能量损失与连接管道的长度、流量的大小、连接管道横截面面积与液压蓄能器横截面面积之比有关。研究结果对液压蓄能器的设计和工程安装有参考意义。
