一个简短的回顾背后的斑点模型的想法。首次在不使用多指数方法的情况下，对液态水中正电子湮没寿命谱进行了解卷积，而采用了适合于描述凝聚态分子介质中正电子偶素（Ps）形成过程的blob模型.斑点模型中的所有可调参数都具有明确的物理意义。与实验结果吻合良好。(c)2006爱思唯尔有限公司保留所有权利。
A brief review of ideas behind the blob model is given. For the first time positron annihilation lifetime spectrum in liquid water is deconvoluted without a usage of the multi-exponential approach, but on the bases of the blob model, which suits well for description of the intratrack processes including positronium (Ps) formation in condensed molecular media. All adjustable parameters in the blob model have clear physical meaning. Excellent agreement with the experiment is obtained. (c) 2006 Elsevier Ltd. All rights reserved.
