Compound 2 had allochroic processes in polar solvents such as methanol or DMF. Acids or alkali such as acetic acid or NaOC_2H_5 also showed apparent influence on the allochroic process.

并对化合物2的变色过程进行了研究，发现该化合物对极性溶剂如甲醇、N，N-二甲基甲酰胺和酸或碱如乙酸、乙醇钠等具有良好的变色过程。

Photochromic rate constant of G1 in CHCl3 and THF was 10－1 s－1, but that of photochromic liquid crystalline polysiloxanes containing azophenyl moieties was 10－8 s－1, thus the photoresponsitive rate of liquid crystalline dedrimer G1 is 107 times larger than that of the latter.

G1的光致变色反应速率常数的数量级为10－1 s－1，而含偶氮基元液晶聚硅氧烷的光致变色反应速率常数的数量级为10－8 s－1，因此液晶树枝状大分子的光响应速率比后者快107倍。

Photochromic reaction rate constant of G2 in CHCl3 and THF was 10－1 s－1, but that of photochromic side-chain polysiloxanes containing azophenyl moieties was 10－8 s－1, thus the photoresponsitive rate of the liquid crystalline dendrimer G2 is 107 times larger than that of the latter.

G2的光致变色反应速率常数的数量级为10－1 s－1，而含偶氮端基侧链聚硅氧烷的光致变色反应速率常数的数量级为10－8 s－1，因此，液晶树枝状大分子的光响应速率比后者快107倍。

And because the fast light performance, not the ink pigment caused by bleeding and chromotropic, not because of aging and yellowing change colour.

又因其具有耐光性能，不造成油墨颜料的渗色和变色，不因老化而返黄变色。

Do these after our business card printing and membership card making products may be solved by chromotropic problem, of course, there is also a problem too, making these efforts our business card printing and membership card making products still chromotropic as soon as the Heidelberg company.

在怠工完这些之后我们的制卡和会员卡制作品不定不离能处置变色题目了，当然也有处置不了的，如果怠工了这些发奋我们的制卡和会员卡制作品还来变色尽快告诉海德堡公司举行修理。

Methods Nail samples were collected from patients with suspicious onychopathy, and inoculated into modified DTM, DTM, Sabouraud dextrose agar fortified with cycloheximide and chloromycetin and Sabouraud dextrose agar fortified with chloromycetin respectively. The initial time of fungal growth and of discoloration of medium, as well as the colony diameter at the beginning of discoloration, were documented.

收集临床拟诊甲真菌病的标本，分别接种于改良DTM、DTM、含放线菌酮及氯霉素的沙氏培养基和含氯霉素的沙氏培养基；记录菌株的开始生长时间、培养基开始变色时间及开始变色时菌落的直径。

Two photo-chromatic organic materials for CD-R/CD-RW are found. One photochromatic organic material for Blue-light DVD-R/DVD-RW is found.
