改色

肤色：底色接近自然皮肤色彩，主要做改色用，能起到中和色彩的作用。

Skin color : the base of color very close the natural skin , it can reach change color and neutralize color effect .

PU贴膜革的印刷改色

Colour - Changing of Polyurethane Leathers by Printing

本文论述了对PU革进行表面印刷改色的可行性。

The possibility of changing the colour of PU leather by printing is discussed in the paper .

TiO2含量对蓝宝石颜色纯度影响很大，也是蓝宝石改色能否成功的重要因素之一。

And the content of TiO 2 effectes the color pureness of sapphire greatly , and it is also one of the important factors whether the sapphire ′ s color can be successfully changed or not .

利用中子辐照改色法把天然无色黄玉改成蓝色黄玉，对天然黄玉和改色后的蓝黄玉分别进行了常规检测、X－荧光测试、紫外－可见光谱测试及红外光谱测试研究。

In the experiment depicted in this paper , the neutron irradiation method was used to change natural topaz color from colorless to blue . The topaz was measured under ultrared spectrum , X fluorescence and ultravioletvisible light spectrum respectively before and after color changing .

结果表明，可利用原矿中的可溶性Fe3＋或外加Fe3＋与碱反应进行改色，可使累托石由深灰－灰黑色变为褐黄色；

The results shown that the clay can be changed into brown from dark grey by using NaOH to react with the soluble Fe 3 + within the ore or applied .

因此，针对性地选择w（TiO2）高的蓝宝石进行改善，或是设法加入TiO2、减少Fe3+含量、在还原条件下改变其TFeO/TiO2的比值，应是目前山东蓝宝石改色的关键。

Therefore , the most important for changing colors of the sapphires is to select sapphires with high TiO 2 and lower the content of Fe3 + , add TiO2 and reduce the ratio of TFeO / TiO2 under reductive condition .

利用傅立叶显微红外光谱、紫外-可见-近红外吸收光谱、低温光致发光谱、拉曼光谱等4种谱学方法，对10颗辐照改色（R1-R10）的彩色天然金刚石进行了研究。

Spectroscopic studies through FTIR , UV-visible-near infrared absorption , photoluminescence and Raman spectroscopy are used to study 10 natural diamonds ( R1-R10 ) with fancy color due to irradiation . These diamonds are classified based on their FTIR characteristics .
