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。

In this thesis, an all-digital phase-locked loop with large multiplication factor is presented. This circuit can be applied to the video system as a clock generator. It receives the horizontal synchronous signal from the graphics card and then generates a high frequency pixel clock according to the monitor resolution setting to acquire the video signal data. The stability of this sampling clock affects the display image quality directly. If the pixel clock is not stable, the display image will be glittering or jittering.
在本论文中,我们提出一个高频率倍数的全数位式锁相回路,此电路可应用於视讯系统中的时脉产生器,其主要功能是接收显示卡发出的水平同步讯号,并依据使用者设定的萤幕解析度,产生高频像素时脉来撷取视讯讯号资料,取样点的稳定度直接影响到显示画面的品质,若是像素时脉不稳定,则显示画面会闪烁或抖动。

PDA(particle dynamics analyzer system) was used to measure the flow velocity of particles in the XFD-12 flotation cell, the results show that tangential mean velocity in the radial direction changes from positive to negative in the flotation cell, naught point emerge in the medium of the radial direction ,it is where backward fluid emerge ,shear stress of backward fluid induce the particle detachment from bubbles .
汁算数据与实际矿石筛析结果都表明,紊流强度增大,泡沫中粗粒级含量减小。 4。用PDA在XFD-12型8L浮选机中测定的速度值,进行混合区、分离区、泡沫区紊流运动功率谱计算,得紊流脉动频率,混合区小于20Hz,分离区在20-30Hz之间,泡沫区在25-35Hz之间,浮选槽内紊流脉动以低频为主,且紊流脉动动能是混合区大于分离区大于泡沫区。
