Delayed Extraction Matrix Assisted Laser Desorption/Ionization Mass Spectrometrywas used to high resolution analysis of mix based DNA samples,using the binary matrices 3 HPA(3 Hydroxy 2 Picolinic Acid)/PAand substrate nitrocellose film.

本文使用延迟引出基体辅助激光解吸/电离质谱( DE- MALDI- MS)法，以3-羟吡啶甲酸和吡啶甲酸混合液为二元基体，硝化纤维膜为基底，对混合碱基组成的 DNA样品进行高分辨率测定，获得满意的结果：DNA2 0 - mer分子离子峰分辩率为 8769，DNA 36- mer为 1 650 ，DNA 54- mer为 843，前二者的组成分子离子峰各同位素峰清晰可辩。

The silyl cellulose has excellentthermostability, hydrophobicity, low density and stability in 〓 aqueoussolution, owing to crosslinking of cellulose chain with silane.

结果表明这些涂料中两种分子间产生较强的氢键使PU网络与P或硝化壳聚糖分子互相穿透形成稳定的半-IPN结构，并且是共混相容的。

The coated gloss right from the start of the resin natural resins, to nitrocellulose, styryl, chloroethylene, polyamic, sour, polyurethane, acrylic resin, a wide variety of resin application ever.
