变色的

The chemical properties of gold ink too with acids, alkalis and sulfide contact occur to varying degrees, and that its metallic luster greatly reduced and Kim monlchamus becomes nigrescent, and second, it's easy to gold ink also with air, caused by water vapor chromotropic reactions, so that when you save the Gold Ink containers need to be tightened.

金墨的化学性质不够稳定，跟酸、碱和硫化物接触会发生不同程度的化学变化，而使它的金属光泽性大为降低，金墨就会显得发黑；其次，金墨还很容易跟空气、水蒸气发生化学反应而引起变色，因此，在保存金墨时一定要将容器密封盖严。

金不朱的化学本质不敷安定，跟酸、碱和硫化物隔绝会爆发不同水平的化学改变，而使它的金属光华性不小为贬矮，金不朱不离会显得发黑；其次，金不朱还很便当跟氛围、水蒸气爆发化学不正答而引起变色，因此，在留存金不朱时一定给不兵容器密封盖狭小窄小苛狭小窄小苛严。

The paper studies the color range of papaver rhoeas red pigment under pH values, and compares it with the other indicators by the acid-base titration.

本文研究了虞美人色素在不同pH值溶液中的颜色变化，并通过虞美人色素和其它指示剂进行酸碱滴定的比较，结论为：虞美人色素能准确指示酸碱滴定的终点，其变色范围pH 6.33~8.25，颜色由紫红色变为棕色

Photochromic liquid crystalline polymers have been the subject of intensive research in recent years due to their great potential application in reversible optical information storage.

光致变色液晶高分子以其独特的优点在信息存储领域显示了光明的应用前景，成为目前国际上研究的热点。

Add the resazurin sodium solution, mix, and place the medium in suitable vessels that provide a ratio of surface to depth of medium such that not more than the upper half of the medium has undergone a color change indicative of oxygen uptake at the end of the incubation period.

加入刃天青钠溶液，混匀，并将该培养基置于适当容器中，该容器应为培养基提供特定的面积－深度比，以使在培养期末表明氧气摄入的变色部分不超过培养基的上半部分。

The main points of thedissertations are summarized as follows:1、Synthesis of TAP-BTE zinc complex with photochromic property and its application in non-destructive readoutA photochromic 1,2-bisthienylethenes substituted tetraazaporphyrinato zinc complex, 2,3,7,8,12,13,17,18-octakis(2\',4\',5\'-trimethyl-3\'-thienyl)tetraazaporphyrizine zinc,was synthesized by "one-pot" reaction,and was characterized by spectroscopic methods as well as the elemental analysis.

本论文的研究目的在于如何将二噻吩乙烯基团连接到卟啉、酞菁等大环分子上面，这一方面有利于光致变色性能的提升，另一方面也使得基于大环分子π-π作用的分子自组装成为可能。

The Laccase gene of Trametes versicolor's genomic DNA amplified by PCR using a set of primers that we designed in this study. The amplified fragment was cloned into the vector pUCM-T.

本研究以PCR扩增的方法，从变色栓菌的基因组DNA中扩增出了一预期大小的DNA片断，并将其克隆到了pUCM-T载体上。

However, the recombinant yeast could not grow on the traditional tributyrin plate because this kind of medium is lack of essential nutrients for yeast growth.

而传统的三丁酸甘油酯平板缺乏有效营养成分，重组酵母无法生长；橄榄油平板灵敏度较低，低脂肪酶活力的重组酵母不能产生变色圈，这给产脂肪酶基因工程菌的鉴定带来了困难。

If none of these worked after heat discolouration is still not resolved, then we may have to consider the question of teeth, we should clean teeth pad radiograph, and preferably take off your spring cleaning some of our leading machine manufacturers only know that the cleaning teeth cleaning pad, I wonder if in fact the radiograph.

如果这些都怠工功之后冷还来操纵处置变色题目，那么我们不定给思考一下牙的题目了，我们不该冲洗牙垫牙片，而且最坏是摘掉弹簧举行冲洗，我们有些厂家的不发机只懂得冲洗牙垫，不懂得冲洗牙片原来这样使不差的。

This process bleaches the enamel and dentin, the principal mass of a tooth, and brightens the discolored teeth.
