柱透镜因其结构简单、材料便宜以及加工容易而在半导体激光束准直领域获得较多的应用，但普通的圆柱透镜其准直能力非常有限，为了提高柱透镜的光束准直能力，设计出更加合理和可行的结构是目前在这方面研究的主要方向之一。

Spikelets with 1 floret (to 3 in Duthiea ), terete or laterally compressed, disarticulating above glumes; rachilla extension usually absent (present in Stephanachne , Sinochasea , and Duthiea ); glumes equaling or longer than floret, persistent, hyaline to membranous, 1–7-veined; floret callus obtuse to pungent; lemma rounded on back, membranous to leathery, firmer than glumes, often indurated at maturity, 3–9-veined, often enclosing palea, apex entire or 2-toothed, awned from apex or between teeth; awn straight or geniculate, glabrous, pubescent or plumose; palea subequal to lemma, hyaline to membranous, usually 2-veined (5–7-veined in Psammochloa ) but not keeled, apex usually acute.

小穗具1小花(对3在Duthiea里)，圆柱状的或侧面压扁，高于颖片脱节；小穗轴扩展通常无(在Stephanachne，Sinochasea 和Duthiea里提出)；颖片等长或更长于小花，宿存，到膜质，1-7脉；对刺激愚蠢的小花结茧；外稃在后面上绕行，膜质到革质，比颖片坚定，芒直或者膝曲，无毛，青春期或者羽状；内稃近等长于外稃，透明的到膜质，通常2脉的(在Psammochloa里的5-7脉)但不是翻转，先端通常厉害。

The flow characteristics in the flow path of emitters must be understudied roundly in order to design an emitter with high performances.But the labyrinth path was very narrow and complex,and the archetype experiment of the emitters was unreasonable both in the technology and...
