糙面的

It is different from traditional concept that the concept dynamic roughness includes influence of model error, truncation error, observation error and so on.

此时的糙率与传统的概念有明显的不同，它包含了模型误差，截断误差，观测误差等各方面的综合影响。

Rubber dam laboratory model experiment: respectively measures the reaeration ability of smooth overflow surface and roughened overflow surface, then contrastively analyses the effect and reason of reaeration improving after roughened modification, and the reaeration effect between curve dam and rubber dam.

橡胶坝复氧室内模型试验：分别测量了光滑溢流面和糙化溢流面的复氧能力，对比分析了溢流面糙化后复氧增强的效果和原因，并对摘要比分析了曲线型溢流坝和橡胶坝的复氧效果。4。

Culms forming large clumps, erect, 10–50(–120) cm tall, 3–35 mm in diam. Leaf sheaths mostly longer than internodes, smooth; leaf blades linear, flat or inrolled upward, 10–45 × 0.7–1.5 cm, smooth, apex fine, hard, upper blades usually patent; ligule 2–3 mm. Racemes racemosely arranged, 2–6(–12), 7–23 cm, stiff, erect or slightly spreading; spikelets closely overlapping; rachis terminating in a hard bristle up to 5 cm. Spikelets 12–21 mm, pubescent; lower glume 2/3–4/5 as long as spikelet, acute; upper glume lanceolate-oblong, as long as spikelet, acute; lemma lanceolate-oblong, ca. 1 cm, keel scaberulous, pubescent, entirely or in upper half; palea slightly longer than lemma.
