Effects of ABT rooting powder No.1 (ABT1),α-Naphthaleneacetic acid and Indolebutyric acid on the rooting rates, biomass and taxol contents of Taxus chinensis var. mairei cuttings were studied in this experiment.

以清水处理为对照，使用不同激素(ABT1号生根粉、NAA、IBA)处理南方红豆杉插穗，从而研究不同激素处理对南方红豆杉扦插苗生根率、生物量及紫杉醇含量的影响。

The nitrosification of suspended activated sludge of SBBR one-step completely nitrogen removal process could be defined as the first order reaction.

单级自养脱氮系统中悬浮态活性污泥的亚硝化反应可以近似按一级反应表示，反应速率随生物量的增加而增加。

Elevated CO〓 to 700μL L〓 enhanced the growth of Nitzschia palea by 4-20％at the beginning of exponential phase, and that of Chaetoceros muelleri by 11-31％in the late exponential phase.

谷皮菱形藻和牟氏角毛藻，在CO〓浓度倍增（700μL L〓 CO〓）条件下，前者的生长从对数期开始受到促进，而后者的促进出现在对数末期；CO〓浓度倍增使稳定期的最大生物量，谷皮菱形藻增加4-20％，牟氏角毛藻增加11-31％。

We also investigated the effects of competition on the growth and biomass allocation of floating-leaved plants Nymphoides peltata using microcosm system.

通过微宇宙系统对不同类型的竞争对浮叶根生植物-荇菜的生长和生物量分配等进行了研究。

Total submergence largely decreased biomass production and growth in length,with less effect on shoot numbers.Increased elongation of the growing internodes of up to 140% is caused by submergence.Nutrient such as N,P,K do significantly affect on growth.No mater lack of any element will decrease the biomass,the result same as the oligotrophic conditions.But lack of phosphorus is the worst mater.

而淹没式淹水可能使生物量降低，但是植株的高度有所增加，因为淹水可以使芦苇的节间高度提高140％；对根茎的数量没有很明显的影响。N、P、K等营养元素对芦苇生长也具有重要的作用，无论缺少哪一种对芦苇生长都不利，跟完全贫营养状态没有明显的区别，但是缺P时芦苇生长是最差的。

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。
