Results With different concentration of sodium arsenite 0.5 ～ 5.0 μmol/L, the skin fibroblasts were markedly stimulated, and a dose effect relationship was observed.

结果与对照组比较，皮肤成纤维细胞经不同剂量的亚砷酸钠诱导后，吸光度值均有改变，存在剂量效应关系（P〈0.01）。0.5～5.0μmol／L浓度的亚砷酸钠对皮肤成纤维细胞有明显的增殖作用，而10μmol／L浓度的亚砷酸钠产生明显的毒性作用。

Experimental result showed that under the wavelength of 460 nm,there was good linear relation between absorbency and content of SO42-;and stationary time that absorbency value needed became longer along with the increase of sample quantity of phosphoric acid.When absorbency become stationary,there is good linear relation between the phosphoric acid sample quantity and the content ofSO42-.So the content of SO42- can be adjusted by turning the sample quantity to make it in scope of standard curve.

实验结果表明，在波长为460 nm处，硫酸根含量与吸光度成良好的线性关系；随着磷酸取样量的增加，吸光度达到稳定值所需的时间相应增加，稳定后磷酸取样量与硫酸根含量成良好线性关系，因此实验过程中可通过调整磷酸的取样量来调节硫酸根含量，使之在标准曲线的测定范围内。

By azo compound became chromophore monomer disperse red -19, and through Sulfonyl of the compound was synthesized by the C, and through 1HNMR its structure was characterized, the results show that the synthesis of compounds C of very high purity, synthetic polymers can meet at the request of the monomer, but also of the compound D, through 1HNMR its characterization, showed that high purity compounds D, is expected to be functional after the adoption of To all the excellent performance PEEK electro-optic polymer materials.

本文通过偶氮化合成了生色团单体分散红-19，并通过磺酰化反应合成得到了化合物C，并通过核磁共振氢谱对其结构进行了表征，结果表明，所合成的化合物C的纯度非常高，完全能满足聚合物合成时对单体的要求，同时也合成了化合物D，通过核磁共振氢谱对其结构表征，显示化合物D纯度很高，应有望通过后功能化合成出各种性能优良的聚醚醚酮电光高分子材料。

In order to determine the saturated vapor pressure of colloid ed dinitrogen tetroxide,and find out its change rule with the various temperature,a testing equipment of determining satuated vapor pressure of colloid ed dinitrogen tetroxide was designed and constructed according to the principle of static testing.

为了测定胶体四氧化二氮的饱和蒸气压，找出其在不同温度条件下的变化规律，采用静态法测试原理，自行设计建立了四氧化二氮胶体饱和蒸气压的测试装置，测得了常压下液体和胶体四氧化二氮的饱和蒸气压数据，结果表明，四氧化二氮体系成胶后比成胶前的饱和蒸气压略有降低，且温度越高其差值越大。
