UV-B radiation induced significant changes in the chemical composition of root, stem, and leaf. Under UV-B radiation, the soluble protein, lignin, and fat contents in leaf, lignin content in root, and cellulose and lignin contents in stem were increased, while the starch content in leaf and the soluble sugar, starch, and fat contents in stem were decreased significantly (P.05), compared with the control.

UV-B辐射处理下根、茎、叶部所检测的大多数化学成分与对照相比均有显著变化：叶片中可溶性蛋白、木质素和脂肪，根中木质素，茎中纤维素、木质素含量在辐射处理下显著高于对照；叶片中淀粉，茎中可溶性糖、淀粉和脂肪含量在辐射处理下显著低于对照(P.05)。

The Zn concentration in leaf and leafstalk increased with increasing Zn supply from 0 to 160 mgL^(-1), but had no increase or even decreased when the Zn supply was higher than 160 mgL^(-1). The Zn concentration in root exhibited a positive correlation with Zn supply and its exposure time, and the kinetic curve of Zn uptake fitted linear-quadratic model, i.e., fast linear uptake first and slow saturation uptake later, with the dividing point at about 1-2 hours' exposure, which could be related with the Zn adsorption on root cell wall and the Zn transportation across the cell membrane.

在0160 mgL^(-1) Zn处理下，植株叶片和叶柄Zn含量随Zn处理水平的提高显著增加，Zn浓度大于160 mgL^(-1)后，植株叶片和叶柄Zn含量不再随介质中Zn浓度的提高而增加，根系含Zn含量与介质中的Zn浓度和培养时间呈正相关，且根系Zn吸收动力学曲线具有二型性，即开始为快速的线性吸收，随后是较缓慢的饱和吸收，两者分界点约在12h，这可能分别与根细胞壁吸附Zn和Zn跨根细胞膜运输有关。

Plant height, leafstalk length, leaf length, leaf width and leaf thickness of water hyacinth did not vary significantly at the range of pH 3.5 to 9.0, while root length, stolon length and root vigor declined obviously with the increasing pH.

随营养液pH值升高，水葫芦的相对生长率从6.12倍降到3.08倍。pH值在3.5—9.0之间，水葫芦株高，叶柄长度，叶片的长度、宽度和厚度在不同酸度条件下无显著差异，根长、茎长和根系活力随pH升高明显下降。

On the basis of introducing the fixed point of Banach theorem, this paper firstly elaborates the important application of the existence of the solution of the linear algebraic equation and the ordinary differential equation, then it narrates the important application of obtaining the leading Newton repetitive process and the natural number the inferior square root and the equation root in the approximate calculation.

本文在介绍Banach不动点定理的基础上，首先阐述了其在线形代数方程、常微分方程解的存在性中的重要应用；然后讲述了其在求导Newton迭代法、求自然数的次平方根、求方程根的近似计算中的重要应用；最后，介绍了其在求一类递推数列极限中的应用。

温脉通是治疗早期动脉粥样硬化闭塞症的有效方剂，临床总有效率达98.1%。

Difference in N uptake responsiveness was linked to their difference in N uptake rate and root characteristics. N uptake rate of high-responding cultivars increased significantly with increasing N rate, while their total root length exhibited a comparatively lower variation.

对氮响应度高的4个水稻品种的平均吸氮速率随着供氮水平的增加其增幅显著，而其总根长的变化幅度则较小。

Cultured in MS medium with different concentration of calcium, explants of Luffa Cylindrica, which could not generate root in usual medium, generated roots with enhanced rates and amounts according to the concentration of supplemented calcium. Moreover, some explants show transformed root from either shoot or flower bud.

在正常Ca2+浓度下，仅激素处理不能生根的丝瓜外植体，处以不同Ca2+浓度处理时，随Ca2+浓度升高，外植体生根数明显加快并增多，且有少量植株叶腋处异化生根，在一定程度上改变了腋芽的发育方向，这说明Ca2+改变了卷须芽或花芽的发育方向，使其发育为根。
