With the increasing of NO3- concentration, the biomass, root absorbability and root absorbing area declined under NaNO3 treatment. The biomass was gradually increased with NO3- concentration increasing under Ca(NO3)2 and KNO3 treatments, while NO3- concentration excessed 98 mmol·L-1, the fresh weight of cucumber seedlings was gradually decreased.

NaNO3处理条件下，随着NO3-浓度增加，黄瓜幼苗生物量降低、根系吸收能力及吸收面积下降；而低浓度Ca(NO3)2及KNO3处理下，黄瓜幼苗生物量随着NO3-浓度增加而增加，当大于98 mmol·L-1时，黄瓜幼苗鲜重逐渐降低。

Through the analysis of the distributions of cold pulverized coal concentration and the area of high concentration zone, it was concluded that the smaller the central air expanding angle was, or the later the secondary air interfused, the larger the area of high concentration zone was.

通过分析冷态煤粉浓度的分布及煤粉高浓度区域面积的大小，得到：中心管扩角越小，二次风混入越晚，冷态高煤粉浓度区域面积越大；一次风率为0.2、一次风速为15 m/s、直流二次风速为25 m/s时冷态高煤粉浓度区域面积较大，有利于降低NOx的生成；内二次风旋流开度减小较外二次风旋流开度减小对冷态高煤粉浓度区域面积的影响大；内旋流强度为1.35、外旋流强度为1.56为最佳的试验工况。

In the absence of coorperative effect, the reaction between lectin molecules and their receptors on cell surface can be described as below when equilibrium is reached:In which LT denotes total lectin concentration, LF free lectin concentration, mva-lency of lectin, ni number of receptors with affinity constant Ki to lectin, CT total lectin concentration.

The Perennial ryegrass, Tall fescue and Red fescue have the largest seed germination rate under the 8 grades NaCl concentration stress. With the concentration increasing, the seed germination of turfgrass sharply decreased. Most of the turfgrass seeds couldn germinate under the NaC1 stress which concentration was above 0.1%, besides the Zoysia, Alkali grass and Creeping bentgrass got a good germination rate.

利用8个梯度（0％，0.2％，0.4％，0.6％，0.8％，1.0％，1.2％，1.4％）的NaCl胁迫处理试验发现，低盐浓度下（培养液〈=0.2％NaCl）草种发芽率以多年生黑麦草、高羊茅最高；随着盐浓度的增加，各草种发芽率迅速下降，当盐浓度达到1.0％时，大部分草种不能发芽或发芽很少，只有结缕草、碱茅及匍匐翦股颖等草种有较好的发芽表现。

The results confirm that NH3 slip increases with both higher ratio of NH3 to NO n(NH3/n and higher concentration of a reducing reagent, while it decreases with the increase of temperature. Initial NO concentration and its residence time can also affect the NH3 slip. A higher initial NO concentration lead to higher NH3 slip, but added residence time has the opposite effect. Among urea, ammonium carbonate and ammonia liquor, the NH3 slip of urea is the highest and that of ammonia liquor is the lowest.

试验结果表明：温度越高，漏失氨含量越低；随氨氮物质的量比的增加，NH3漏失含量不断增加；还原剂质量浓度越低，NH3漏失含量越低； NO初始浓度和停留时间对漏失氨浓度也有影响，NO初始浓度越高NH3漏失浓度越高，停留时间越长漏失氨浓度越低；不同还原剂NH3漏失浓度不同，尿素、碳酸氨、氨水3种还原剂中，尿素的NH3漏失浓度最高，氨水的NH3漏失浓度最低。

Under P-deficiency stress, IAA concentration in asparagus bean plant increased, and IAA translocated from shoot to root, then IAA concentration in root increased, and the ratio of IAA concentration in root/that in young stem and leaf increased, then the ratio of root/shoot increased, due to more carbohydrate translocated to root.

缺磷胁迫下长豇豆幼苗IAA浓度升高，并从地上部向根系运转，使根系IAA浓度和根系IAA含量/嫩茎叶IAA含量的比值升高，增强了碳水化合物向根分配的力度，促进了根冠比的提高，对缺磷敏感的二芦白升高最大，因而根冠比也升高最大。
