小剂量辐射对肿瘤细胞K_（562）及肿瘤病人天然杀伤细胞（NK）活性的影响

已知小剂量辐射可增强机体免疫功能。从对高本底地区的调查发现，该地区居民肿瘤死亡率及某些肿瘤发病率有所降低（１）。ＮＫ细胞能直接杀伤肿瘤细胞，在肿瘤免疫中起着重要的作用。本文观察小剂量辐射对肿瘤病人和正常人外周血淋巴细胞ＮＫ活性的相对效应以及对人红白血病细胞（Ｋ（５６２）细胞）的影响，以期从体外买验来探索较小剂量辐射对肿瘤治疗的影响     

新型实用布线算法──L─M算法

本文提出新型布线算法，集李氏迷宫法与线搜索法的长处为一体，以饱和带法进行动态排序，以线搜索法确定借孔位置，然后用李氏法进行单层布线，获得最佳路径，从而达到线型好，布通率高的效果。     

~（131）Ⅰ—MIBG比活度对鼠心肌交感神经囊泡内外摄取的影响

研究了两种比活度的１３１Ⅰ－ＭＩＢＧ在正常及利血平抑制后在鼠体内的分布，结果表明：注射后４ｈ，正常鼠心肌对３．２２ＴＢｑ／ｇ的ＭＩＢＧ摄取为９．０８％ＩＤ／ｇ，明显高于对１８．５ＧＢｑ／ｇ的摄取（４．８７％ＩＤ／ｇ）。计算表明，比活度主要影响了鼠心肌交感神经囊泡内摄取，而与囊泡外摄取无关．当ＭＩＢＧ用于心肌显像时，高比活度的ＭＩＢＧ有利于诊断。     

On the construction of the reachability domain in one nonlinear problem

An algorithm for construction of the reachability domain by the given time instant ? for a nonlinear third order system under the condition of preliminary approach to a predefined point is proposed. All possible cases of location of this point in the motion plane of the system for different values of the time instant ? are studied.

Adaptive Optimal Nonlinear Filtration and Certain Related Topics. II

The properties of the solutions of optimal parametric filtration equations and an adaptive variant of the problem with regard for time-drift of the unknown parameters of the system are studied. Along with the Kalman interpretation of the optimal adaptive nonlinear filter, the Bayes approach to applying the respective a posteriori densities is also studied.
