节间的

To further reveal the structure of monocotyledon lignin, carbon 13 enrichment of specific carbons of rice stalk lignin was achieved by feeding coniferin [α 13 C], coniferin [β 13 C] and coniferin [γ 13 C] into an internode cavity of the stalk of a growing rice plant Oryza sativa L.

为了进一步了解单子叶植物的木素，向生长中的水稻(OryzasativaL 。)茎秆节间的腔体分别注入在侧链α、β、γ位带13 C标记的松柏醇葡萄糖甙，得到侧链带13 C标记的稻秆木素。

Culm sheaths longer than internodes, to 26 cm, very sparsely yellow-brown setose, apex leathery and flat.

节间的竿箨长于，在26厘米，具刚毛的黄褐色，似皮革和平的顶的非常稀少。

Young culm internodes pubescent only; culm sheath blade both strigose and pubescent.

仅年轻的秆节间的短柔毛；都的竿箨叶片具糙伏毛的和短柔毛。

Lower internodes of culms glabrous; culm sheath apically subtruncate; auricles subequal, usually reflexed.

低节间的无毛的秆；顶部的竿箨近截形；近等长的叶耳，通常反折。 3 B。 sinospinosa 车筒竹

The results showed that the breaking-resistant strength of basal culms was a good parameter for quantifying the culms intensity.

说明改善水稻茎秆的质地结构、增加基部节间的充实度是提高水稻的抗倒伏能力的关键。

Data were collected related to plant growth (stem length and number of internodes) and yield.

收集相关的植物生长（茎杆的长度和节间的数量）及产量的数据。

Culm internodes with fine conspicuous ridges; leaf sheaths 4.2–6 cm.

与好的显眼的脊节间的Culm；叶鞘4.2-6 厘米 33 Y。

Culm internodes initially purple spotted; culm sheath oral setae 3–6 mm; pseudopetioles glabrous, leaf blade secondary veins 5–9-paired, tessellations square

节间的Culm 最初紫色斑点；竿箨口头的刚毛3-6毫米；无毛的假梗，5-9配对的叶片次脉，棋盘花纹广场 47

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
