The cadmium endurance of Salix×aureo-pendula clones was evaluated by principal components analysis and subordinate function analysis. Results showed that the seven significantly different cadmium endurance indexes could be classified into five component parts: plant growth rate, chlorophyllous content, MDA content, dissociative proline content and dissolubility protein content.

The results indicated that the concentration of Cu in the soil is 220.16 mgkg^(-1) contrast to the CK 500.31 mgkg^(-1) significantly decrease when the concentration of EDTA in the soil is 2 mmolkg^(-1) that explains EDTA treatment significantly decreased soluble Cu content in soil because of translating into Cu of water distill floating on the surface of soil and most accumulating around root. Contemporary, application of EDTA to the soil significantly enhanced mobilization of Cu in soil and increased Cu uptake in shoot of Leersia hexandra Swartz., the highest concentration in the leaves 336.54 mgkg^(-1) is 4 times higher compared with the ck 80.34 mgkg^(-1). However, citric acid, oxalic acid and malic acid inhibited mobilization of Cu and less significantly affected shoot Cu accumulation.
结果表明,当向土壤中施加质量摩尔浓度为2mmolkg^(-1)的EDTA时,土壤中Cu质量分数为220.16mgkg^(-1)与空白土壤中500.31mgkg^(-1)相比明显减少,说明EDTA可以极显著的降低土壤中的铜质量分数,使其转化成水提取态的Cu浮于土壤表面,并大部分聚集在根部周围,同时向土壤中施加EDTA不但促进了对Cu的活化而且显著提高了李氏禾对Cu的吸收,叶中最高质量分数达到336.54mgkg^(-1)是对照中80.34mgkg^(-1)的四倍;而柠檬酸、草酸和酒石酸则抑制了Cu的活化,但对李氏禾地上部分的Cu质量分数影响不大。

Results In vitro recovery of the probe was mainly influenced by the perfusion rate. When the perfusion rate was set at 1.0μL/min, in vitro and in vivo recoveries of the probe were 50.16±2.34% and 14.096±0.58%, respectively. The enhancement indexes for 3%, 5% mentha oil were 3.8 and 17.6, respectively. The enhancement indexes were 9.2 and 24.8, for 3% and 5% of Azone, respectively. Conclusion The steady sate flux of meloxicam in rats is significantly improved by enhancer mentha oil and azone.

Based on this, aim at the disadvantage on Wigner Distribution and Fractional Fourier Transform that can't restrain noise interference effectively when be used to detect Linear Frequency Modulated signals interfered by heavy noises, we proposed a improved WD. Simulation results show that this method can restrain noise interference effectively and improve the ability of LFM signals detection. On the other hand, in multi-component cases, WD suffers from the cross-terms, which may impair some of the auto-terms. In order to separate original multi-component signals into components and reconstruct them separately, we can use the method of optimal filtering in fractional Fourier domain. But this method also has a problem that if signals have aliasing in the fractional Fourier optimal domain as well, the reconstructed signals will be distorted. In this thesis, a novel method of quasi Fourier transform is proposed in order to solve the problem of multi-component signal reconstruction, and have good results.
