The results show that: from the subcircuit that is furthest to the heat source to the nearest one,the stability of DRS becomes gradually worse;the stability of RRS is symmetrical,with the subcircuit in the middle of the pipe-network having the worst stability,while,the nearer to the two ends,the better the stability of the subcircuits is.

结果表明，异程系统从离热源最近的支路到最远支路，稳定性依次变差；同程系统的稳定性具有对称性，网路中部的支路稳定性最差，越往两端，支路的稳定性越好；从总体上讲，同程系统的稳定性差于异程系统。

The method is based on a variable structure to control the SVC, wherein, the variable structure control method comprises two aspects of the unbalanced load equalization compensation and the parameter control of a PI controller, wherein, the unbalanced load equalization compensation adopts the SVC compensation susceptance computational method which is based on the synchronous rotation reference coordinate transformation of a virtual symmetrical three-phase system; meanwhile, in the stabilization control of the system voltage, the ant colony algorithm optimization method is adopted to real time adjust and to optimize the parameter kp and ki of the PI controller.

本发明公开了一种静止无功补偿器的不平衡补偿和蚁群优化方法，基于变结构对静止无功补偿器SVC进行控制，其中变结构控制方法包括不平衡负荷平衡化补偿和PI控制器的参数控制两个方面，其中不平衡负荷平衡化补偿采用基于虚拟对称三相系统的同步旋转参考坐标变换的SVC补偿电纳计算方法；同时在系统电压稳定控制时，采用蚁群算法优化方法，对PI控制器的参数kp、ki进行实时调整、寻优。

We describe a seven-generation large family with talipomanus and talipes, 175 individuals in this family were involved. 32 affected individuals including 18 males and 14 femals whose clinical features were different and 1 suspicious male were found. The talipomanus were symmetrical, and varus and valgus were caused by vertical talus.

发现一个连续遗传 7 代的手足畸型大家系，共计 175 人，有 32人发病，男性 18人，女性 14 人，可疑男性1人，患者表型复杂轻重不一，但双手均对称屈曲畸形，垂直踞骨导致足内翻或外翻。

I A is more stable than B, and the two equivalent tautomers of 9-HPO can tautomerize through IHT. B is the transition state for IHT of 9-HPO. ii B was in a symmetrical plane. The charge of hydrogen and molecular dipole moment of B are higher than that of A, so the IHT rate will be accelerated in polar solvents.

另一方面IHT也使此类分子表现出某些优异的物理化学特性，比如：具有IHT的羟基艺北醌类化合物可以用作光疗药物，用于治疗肿瘤、爱滋病等顽症，还有望成为光电转换的新材料[2 ] 。

Results Abnormal signal lesions were found in 47 patients with viral encephalitis, including multiple or single, symmetrical or asymmetrical large patch shape lesions, the located mainly in cortices, subcortical and basal ganglia and thalami. The lesions carried long T 1 and long T 2 on MRI. Enhanced MRI was performed in 22 cases, and demonstrated abnormal enhancement in 11 cases, including large patch or gyrus shape enhancement in 7 cases.
