查询词典 separation

A method of killing flying insects which method comprises spraying into the air in which insects are flying liquid droplets of an insecticidal composition, a unipolar charge being imparted to the said liquid droplets by double layer charging and charge separation during spraying, the unipolar charge being at a level such that the said droplets have a charge to mass ratio of at least +/-1x10-4 C/kg.

一种杀死飞虫的方法，该方法包括：向具有飞虫的空气中喷射杀虫剂组合物液滴，在喷射过程中通过双层充电以及电荷分离而向所述液滴施加单一极性的电荷，单一极性的电荷处于使所述液滴具有至少＋／－1×10-4C/kg的电荷／质量比的水平。

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。

A weepy session on relationships (only children are more likely to change partners through divorce or separation than those with siblings, according to the latest findings from the National Child Development Study) ends with a loud and crackly broadcast of "I Am the One and Only", the horrible 1991 hit by teen singer Chesney Hawkes.

Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.

结果表明，受S素营养胁迫的水稻，其根系及叶片的超微结构均发生了显著的变化：低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀，基粒片层松驰、散乱，细胞器减少，线粒体结构被破坏，根系细胞内几乎没有内含物；S浓度高则会使叶片叶绿体基粒片层致密、浓缩，无规则化，根系细胞发生质壁分离。
