According to the analysis of principle components,the breeding materials with higher plant height, mediate stem perimeter, thickerbast fiber, higher rate of bast fiber to stalk, should be selected to resolvethe conflict between quality and yield in kenaf breeding.

根据主成分分析结果，在品种选育时，应注意选择植株较高、茎粗中等、韧皮较厚、皮骨比较高和高出麻率和品质优良的材料，以协调品质与产量的矛盾。

Herb widely distributed in tropics and subtropics used for forage and medicinally as a demulcent and having a fine soft bast stronger than jute; sometimes an aggressive weed.

广泛分布在热带和亚热带的一种药草，被用做草料和医药上的镇痛剂，有优良的软的比黄麻结实的韧皮；有时是一种有侵略性的杂草。

Our outside and often thin and fanciful clothes are our epidermis, or false skin, which partakes not of our life, and may be stripped off here and there without fatal injury; our thicker garments, constantly worn, are our cellular integument, or cortex; but our shirts are our liber, or true bark, which cannot be removed without girdling and so destroying the man.

穿在我们最外面的，常常是很薄很花巧的衣服，那只是我们的表皮，或者说，假皮肤，并不是我们的生命的一部分，这里那里剥下来也并不是致命伤；我们经常穿着的、较厚的衣服，是我们的细胞壁，或者说，皮层；我们的衬衣可是我们的韧皮，或者说，真正的树皮，剥下来的话，不能不连皮带肉，伤及身体的。

RESULTS : The vascular bundle structure is much complicated than the phellem structure and bast structure .

结果：通过对中药材异常构造特点的综合系统分类研究，指出木栓组织，韧皮组织和维管束组织等方面的异型构造，其中维管束异型构造较为复杂。

During its growth and invasion in the host, it can produce phytotoxin, pectinase and cellulase to overcome the tree resistance and stain the host's tissues to blue, inducing the disease symptoms, such as phloem necrosis, namely phloem reaction zone, etc.

该菌在云南松体内的生长侵染过程中，将产生毒素和分泌纤维素酶、果胶酶等酶类以突破寄主组织的防御屏障，使云南松组织发生蓝变，产生病害，诱导形成韧皮坏死区域等症状。

Any of various vascular plants , including seed plants and ferns , having a conducting system of xylem and phloem .

导管植物任何种类的管植物，包括种子植物和蕨类植物，具有和韧皮导管系统

This observation provided a strong support to the point that most leaves export the most of assimilates in the light time. Plasmodesmal densities between SE/CC, CC/PP, PP/PP and PP/BSC (bundle-sheath cell) decreased in weak light. Plasmodesmata were observed between CC/SE (nacreous-walled sieve element), PP/BSC in branch veins in normal light intensity, but not in weak light. Thus apoplasmic pathway may be the main mode of transport of assimilates in weak light, however symplasmic pathway may be the main mode of transport of assimilates in normal light intensity.

在筛管/伴胞、伴胞/韧皮薄壁细胞、韧皮薄壁细胞/韧皮薄壁细胞和韧皮薄壁细胞/维管束鞘细胞之间的胞间连丝密度都在弱光条件下下降，在正常光照强度下支脉筛管/伴胞和韧皮薄壁细胞/维管束鞘细胞之间可以观察到胞间连丝，而在弱光下几乎观察不到胞间连丝的存在，所以同化物的运输在弱光条件下可能以质外体运输为主，而在正常光照强度下，共质体运输可能是主要的运输方式。

Therefore, pretreatment of raw flax was performed with selected chelating agents such as ethylene diamine tetraacetic acid, sodium tripolyphosphate, oxalic acid and ammonium oxalate.

选用EDTA、多聚磷酸钠、草酸和草酸铵等螯合剂对亚麻原麻进行了预处理，结果表明：EDTA、草酸、多聚磷酸钠的处理效果均不理想，改变浓度、温度等条件，韧皮与麻秆并没有分离；而草酸铵是比较有效的螯合剂，用5 g/L的草酸铵在62℃处理亚麻原麻5 h后，韧皮与麻秆能够完全分离。

Research: pH4.0, enzyme concentration of 5g.L^(-1), temperature 40℃, time 96h enzymatic conditions, can remove the cotton stalk bast lignin 43.6% pectin 25.1%, the preparation of cotton stalk phloem technology fiber fineness 3.35~3.65tex; the average length of 84.5mm.

研究结果表明：pH 4.0、酶浓度5g/L、温度40℃、酶作用时间96h条件下，可去除棉秆韧皮果胶质43.6%、木质素25.1%，所制备的棉秆韧皮工艺纤维细度3.35~3.65dtex，平均长度84.5mm。

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。
