查询词典 linear correlation

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。

RESULTS The SOD activity had linear correlation with pH in the range of pH 2.2-8.0 when SOD concentration was fixed. The varication of activity after ultrosonication had linear correlcation with fluoresent intensity at 340 nm. With increase of uhtrosonic frequency, the microenviroment of tyrosine and tryptophan inside the SOD molecule was changed, then the balance of hydrophokicity and hydrophilicity inside the molecule was broken, this induced the blue shift of synchronous spectrum band and decrease of SOD activity.
