In this study, for the complicated distribution of dose rate in time and space, considering the repair of the sub-death cells, the radionuclide decay law and exponential proliferation of clonogenic cells, the dose-response relationship is built based on the known linear-quadratic model, and the concept of tumor control probability is introduced into the therapy method. Furthermore, the concepts about "curable stage" and "critical time point" and the methods calculating the amount of radionuclide injected into tumor in clinical are proposed.

本课题针对这一方法中靶区复杂的剂量率时-空分布特点，以公认的"线性-二次模型"理论为基础，同时考虑亚致死性细胞修复、核素衰变规律和克隆原性细胞指数增殖，建立了适合这一治疗方法的具有时-空分布特点的剂量效应关系，并进一步将肿瘤控制概率的概念引入这一方法中，提出了"治愈期"及"临界时间点"的概念以及由此指导临床确定药物注射剂量的方法。

Observation of transmission electron microscope reveals that the f＇me structure of CGHAZ and IRCGHAZ of both in- service welding and routine is ferrite laths and the second phase particles that distribute on or between ferrite laths.

透射电镜下，在役焊接和常规焊接的粗晶区与临界粗晶区的主要形貌都是铁素体板条和分布在板条之间或板条基体上的岛状物，铁素体板条的亚结构都是高密度位错。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
