The relationship between molecular structures of the DIAR couplers and photographic characteristics is also discussed .

并探讨了DIAR成色剂分子结构和照相性能的关系。

, disclosed in Oct. 1991 a new generation of DIAR couplers .

Lau于1991午10月提出的新一代的DIAR成色刑的结构（？）

Kinetics of the development inhibitor releasing coupler in the color imaging process ⅰ . the reaction of dir and DIAR coupler with QDI in gelatin layer

释放显影抑制剂型成色剂在彩色影像形成过程中的动力学研究Ⅰ.在明胶层中DIR和DIAR成色剂与QDI反应的动力学

The application of three DIAR couplers in color negative film is studied , and the data of sensitivity , fog , particularly , reduced graininess , improved interlayer effect have been obtained .

对3个DIAR成色剂在彩色负片中的应用进行了研究，得到了它们对感光度、灰雾影响的数据，特别是得到了它们在降低颗粒度和改善层间效应方面的数据。

The inhibitor released from the reaction of DIR or DIAR coupler with QDI decreases the development rate of silver halide grams , so it controlled the formation rate of QDI .

DIR和DIAR成色剂在与QDI反应后所释放的显影抑制剂抑制了卤化银的显影进程，从而控制了QDI的形成速率。

Two DIAR couplers were synthesized with 2 ( isopropylamino ) benzenethiol as timing group , which was synthesized from benzothiazole and triphosgene used as a substitute of phosgene , and good result was obtained .

从苯并噻唑开始，制备了2异丙氨基苯硫酚，并把它作为定时基团，合成了2种DIAR成色剂。在中间体的合成中，用固体光气代替光气得到了理想结果。

From four aspects of timing group , inhibiting group , coupler group and whole molecule , the development of DIAR coupler is reviewed in the last ten years . In particular , a few of DIAR coupler with new structure or new function are introduced .

本文分别从定时基团、抑制基团、成色母体和分子结构这4方面介绍了近十几年来DIAR成色剂的最新进展，特别介绍了一些具有新结构和新功能的DIAR成色剂的情况。

Based on the rate constants of the reaction of dye-forming coupler , DIR coupler and DIAR coupler with QDI respectively , the effects of DIR or DIAR on the essential reaction of dye image formation were investigated .

继前文测定了成染料成色剂、DIR和DIAR成色剂与QDI的偶合反应的速率常数的基础上，本文进一步研究了DIR和DIAR成色剂对染料影像形成的主反应的作用。

The results showed ( 1 ) that DIR or DIAR coupler competes with dye-forming coupler for QDI , so it could control the diffusion range of QDI and decrease the rate of dye formation of the dye-forming coupler ;

研究结果表明其作用（1）DIR或DIAR参与与成染料成色剂竞争QDI的反应，从而控制了QDI在显影银周围的扩散距离，同时也影响了染料的形成速率；
