As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.

薄膜干涉式晕彩不仅要求宝石内部结构层的厚度必须在一定的纳米范围内，而且结构层内部的折射率也必须有所差别，也即，当结构层由两相组分出溶而成，其化学成分、折射率和结构层厚度形成三位一体时，符合薄膜干涉式晕彩，如拉长石、钠长石、石榴石和角闪石；而光栅式衍射晕彩则仅要求结构层排列规则，边缘狭窄但不需要窄到可见光波长范围内，能使入射光的振幅或位相，或两者同时产生周期性空间调制的结构即可，如鲍贝壳、珍珠和欧泊。

In the medium of 0.013 mol/L H2SO4, phosphate reacts with sodium molybdate and potassium antimonyl tartrate, forming a yellowish phosphorus-antimony-molybdenum heteropoly acid. The acid exhibited a strong resonance scattering peak at 710 nm after added with nanogold. The heteropoly acid was reduced by ascorbic acid to antimony phosphomolybdate blue, which caused the decrease of resonance scattering intensity.

在0.013mol/L H2SO4介质中，磷酸根与钼酸钠、酒石酸锑钾反应生成淡黄色的磷锑钼杂多酸，加入纳米金后在710nm处产生一个较强的共振散射峰，抗坏血酸可将磷锑钼杂多酸还原为磷锑钼蓝，导致710nm处共振光散射信号降低。

Sodium chromium chlorophyllin is soluble in water, stable in the neutral solution, and resistant to oxidizing agent and reducing agent. Its thermostabillity is good, but photostability weak.

The results indicated that under photooxidation condition, the addition of "RuBP regeneration system" and sodium glycolate increased qP and Φ, while R5P, DHAP and HCO(superscript – subscript 3) increased qN, compared to nonphotooxidative control.

结果表明，光氧化条件下外加"RuBP再生系统"和乙醇酸钠可提高qP和Φ，而R5P、DHAP和HCO(上标–下标 3)可提高qN，显示其对光氧化下叶绿体PSII活性有一定程度的保护作用。

However, common polyacrylate emulsion has some disadvantages such as poor water-resistance, poor film-forming in low temperature, becoming pastiness in high temperature, polluting environment with emulsifier and so on.

由于聚丙烯酸酯乳液具有耐热、耐光和耐老化等优点在涂料工业中得到了广泛的应用，但普通的聚丙烯酸酯乳液还存在耐水性差、低温下不易成膜、高温发粘以及含乳化剂的废液会对环境造成污染等缺点，因此，本文结合无皂乳液聚合和核壳乳液聚合技术，合成了聚丙烯酸丁酯/丙烯酸钠齐聚物，并以此为乳化剂，采用种子半连续法合成了以聚丙烯酸丁酯为核，聚甲基丙烯酸甲酯-苯乙烯为壳的无皂核壳聚丙烯酸酯乳液。
