The light curve of five kinds of landscape lianas commonly used in southern China were measured by LI-6400 portable photosynthesis system and fitted by non-rectangular hyperbolic model. Light compensation point, light saturation point, Pn,ɑ of the 5 lianas species were analyzed comparatively. The results indicated that there are significant differences in light response of photosynthesis among them.

采用Li-6400便携式光合测定仪对5种华南地区常用园林绿化藤本植物进行了光响应曲线的测定，并用非直角双曲线模型对其进行拟合，对比分析了5种藤本植物的光补偿点、光饱和点、最大净光合速率、最大表观量子效率。

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。

There will be lots of observational data in the field experiments, the temperature data in the other bores at the same elevation of the leakage passage is selected and curve fitted under the logarithmic equation model. As a result, the radius of the leakage passage can be calculated.

而现场测试试验中有大量温度观测数据，提取与渗漏通道同一高程其它钻孔的温度值，并将这些实验数据在对数函数理论模型下进行曲线拟合，从而可以计算出渗漏通道半径。

Segmentation and extraction of the target feature points from the unregistered, noisy data set of human body scanning and measuring are discussed. We have fitted the noise scanned data line with KS principal curve, which is based on the K-means theory. The crossing zero of curvature was used to segment and estimate the position of target feature points. And optimization scheme named variable fuzzy partition is also presented to improve the searching for local feature area.
