Spikelets 4–5 mm, dark brown, pallid near apex, keels green; callus hairs 1/2 spikelet length; lower glume lanceolate, back flat, densely hairy with silky hairs ca. 1.5 times spikelet length or more, veinless between keels, apex obscurely emarginate or 2-mucronate; upper lemma narrowly oblong, shortly 2-toothed; awn 0.8–1.5 cm, fine, almost straight.

小穗披针形的到狭长圆形，背压扁；胼胝体短，具髯毛，不到1/2的小穗长度的通常毛；颖片软骨质的到革质；更下部的颖片平或稍凹，有毛，背无脉或不明显，侧面圆形在下半部，龙骨状向先端，锐尖到截形；舟状的上面颖片，沿着midline龙骨状的1；更低的小花退化至一空的透明的外稃，很少无；上面外稃线形到长圆形，偶有宽，2齿或2裂的至中部，具芒的E。

Sessile spikelet 3.5–4.5 mm, pallid; callus hairs 1/8 spikelet length; lower glume oblong-lanceolate, membranous, back slightly concave, villous except near apex, veinless between keels, upper keels smooth or pectinate-scabrid, apex narrowly truncate or 2-toothed; upper glume apex with 2–2.5 mm awn; upper lemma narrow, 2-toothed in upper 1/4; awn ca.

无梗小穗3.5-4.5毫米，灰白色；胼胝体毛1/8的小穗长度；长圆状披针形的下部的颖片，膜质，背稍凹，除近先端之外的具长柔毛，上面颖片先端具2-2.5毫米芒；在上面1/4里狭窄，2齿状的上面外稃；芒约1厘米，柱子具短缘毛。

The lower part has cardan rolling wheels , and the wheels can rotary flexible , it can make sure that the tote cart arrive the appointed place smoothly .

A cotton ball was placed in the lower pharynx and a suction device was placed for drainage, so as not to cause aspiration of saline.

鼻咽腔降温组：将气管插管的大鼠咽喉下部置一棉团和吸引设备避免误吸。

The conclusion of three burning methods mentioned above during the heat storage period is that the first method is the best one, which is propitious to keep higher blast temperature because of the heat exchange in the middle and blow of hot blast stove has been aggrandized through convection heat transfer caused by the added exhausted air quantity and increased flow rate.

以上三种燃烧制度，在蓄热期：第1种因废气量增大，流速加快，利于对流传热，强化了热风炉中下部的热交换，利于维持较高风温，第2种因废气量减少，不利于传热和热交换的强化，不利于维持较高风温，第3种由于废气大量减少，流速降低，传热减缓，蓄热量较少，不利于提高风温。

Consequently angularities are apt to occur both below and above unconformities.

因此，交角往往出现在不整合面的上部或下部。
