Composite membrane was applied in the desalination-purification for dye KB-R, and the rejection for KN-R was kept at nearly 100% and the flux waved about 45L/m h. The dye KN-R was almost desalinized through 8 times cycle.The separation properties of three hollow fiber composite membranes for nucleotide containing phosphate were tested at 0.6MPa, room temperature.

在室温、0.6MPa下，考察了CMa，CMb和CMc三种复合纳滤膜对含有磷酸盐杂质的核苷酸的分离性能，膜CMc对核苷酸的截留率最高(达97.9％)，同时膜的通量也较大(为27.5L／m~2h)，因此选用膜CMc作为核苷酸分离用复合纳滤膜(来源：A586d0dBC论文网www.abclunwen.com)。

Extracted DNA by CTAB, in proportion to the additions of PVP and β-mercap toethanol to the extraction buffer were capable of preventing browning from taking place in the extraction, Tris-Phenol (Stabilized with 0.1M Tris, pH 8.0)/Chloroform/isoamyl alcohol were used to remove protein and impurity in the second extraction, during crude DNA used to Isopropanol DNA and deterged by DNA detergent, without using RNase remove RNA, we detected the quality and concentration of DNA respectively for normal leaves and drought stress leaves by Agarose gel electrophoresis of genomic DNA and ultraviolet spectrometry photo.
