摘　　要：本文用微波光导法研究了单注法所制备的多分散性的卤化银乳剂的碘含量与光电导的关系.工作表明,随着乳剂微晶体中碘含量的增加。光电导明显地降低,在8mol％碘含量时达到一个最小值,随后随着碘含量的增加又稍微有所增加。这一结果对于正确认识单注法乳剂的潜在的发展余地具有重要的意义。The emulsion of silver bromide containing varying amount of iodide impurities has received considerable attention recently. In present paper the dependence of iodide content on the photoconductivity was studied with a microwave photoconductivity technique. It was shown that during the exposure the photoconductivity was decreased strongly with the increase of the iodide content, reaching a minimum at the point of 8 mol% , then a slight incr(?)e in the range from 8-15 mol%. This result is the important significance in correct exploiting and understanding the potential development of the emulsion prepared by single jet method.
