＜正＞The nature of the multirate dynamics of the process makes it very attractive for applications, since the multirate phenomena are complex. In this paper a method for reception of the description in state space for a three-rate autonomous continuous-time stochastic control system and the block diagram of functioning of all subsystems with optimal regulators are offered. The proposed control system design was successfully applied to design a highly accurate position control of the Lockheed L1011 aircraft. Simulation and animation results with the help of a simulation modelling packet SIMULINK show the quality of the proposed method and demonstrate that this design technique would work for real systems.

多数抗病毒制剂为核苷类似物目前使用的制剂为核苷类似物,对病毒复制有选择性作用。如阿糖腺苷为一嘌吟核苷,首先用于单纯疱疹病毒(HSV)脑炎及新生儿疱疹感染,能有效地降低死亡率及神经后遗症。阿糖腺苷为细胞激酶磷酸化后成为三磷酸盐,为病毒DNA多聚酶的抑制物。在实验室内虽可产生耐药病毒株,但在临床上问题不大。 Acyclovir[9-(2-羟二氧)甲基鸟嘌呤]为一鸟苷类似物,临床上对HSV和水痘-带状疱疹病毒(VZV)有效,因其相对无毒性作用。

翻墙、爬树、跨栏、奔跑,过去没有电脑没有游戏的时候,身边的一切就是小孩子的玩具。而今,在简单的追逐游戏基础上加入高难度动作,和嘻哈音乐、视频以及网络结合起来,跑酷风从法国蔓延到世界各地。有人把它叫作free running,玩家们常常简称为PK,这项新的极限运动会让人回想起无拘无束的童年——那个年约17岁的男孩准备好了,他像猫一样蹲伏在狭窄的、离地面有三四层楼高的走道上。突然,他跳了起来。

AIM: To compare irritable bowel syndrome (IBS) pa- tients with apparently healthy persons and to evaluate body awareness therapy, which is a physiotherapeutic remedy focusing on normalising tensions in the body, for the treatment of IBS with the hypothesis that altered body tension is associated with the syndrome. METHODS: Twenty-one IBS patients received body awareness therapy two hours weekly for 24 wk. At base- line as well as after 12 and 24 wk, they underwent ex- aminations including resource oriented body examination in combination with body awareness scale evaluation and f illed in gastrointestinal and psychological symptom questionnaires. Saliva cortisol was analysed. A group of 21 apparently healthy persons underwent the same ex- aminations once. RESULTS: Compared to the apparently healthy group, IBS patients scored higher at baseline for gastrointestinal and psychological symptoms. They showed more often alterations in normal body tension patterns, as well as deviating cortisol slopes in saliva. After 24 wk of body awareness therapy, their gastrointestinal and psychologi- cal symptoms were reduced overall. Somatic symptoms decreased in parallel with depressive symptoms. Whole body pain score decreased, coping ability as well as bio- chemical stress markers improved. CONCLUSION: IBS patients scored higher for gastroin- testinal and psychological symptoms, and presented with altered biochemical stress markers. Their body tension deviated compared to healthy controls. Furthermore,body awareness therapy gave relief of both somatic com- plaints, psychological symptoms and normalised body tension. These findings indicate that distorted tension constitutes an important part of the symptoms in IBS.
