Central inhibition, discovered by Sechenov in 1862, suggests that electrically stimulating the forebrain or medulla oblongata in frog generally suppresses reflexes. However, the underlying molecular mechanisms are still unclear. Using ethanol (EtOH), noradrenalin (na), and other neurotransmitters in thalamic preparations, Sechenov inhibition was stimulated in Bufo toads in this study. The result showed that, similar to Sechenov inhibition, the acute application of EtOH or na excited the thalamus and prolonged the latency of withdrawal reflex. Our study evidences the involvement of α-adrenoceptors in such central inhibition, and explains the role of acute EtOH application in the in- duction of reflex inhibition.

Some results in the law of logarithm for na sequences are obtained, which are similar to the result of id random variables; as a corollary, a sufficient result for the bounbed law of logarithm for na arrays is given. Meanwhile, A conjecture for id random variables of Gut is answered in na setting. Under weaker moment conditions than Su and Qin’s, a stronger convergence resuit than their Theorem 1 is obtained.

The phase diagram of system na2O-Al2O3-H2O has been investigated by many authors. The left part （Al2O3·3H2O as solid phase） of the diagram of na2O-Al2O3-H2O system is of no problem, but the right part （hydrated sodium aluminates as solid phases） is in controversies. Jucaitis concluded that there were two hydrated sodium aluminates, i.e. na2O·Al2O3·2.5H2O and 3na2O·Al2O3·6H2O. Kuznetsov suspected the existence of the latter and believed that it was actually a mixture of na2O·Al2O3·2.5H2O

基于MP2/6-311+G(d)水平,分别对过渡金属Ti和碱金属na与O2的反应机理进行了研究.比较了Ti和na分别以垂直O—O键和沿着O—O键的方向逼近O2,以及中性体系Ti/na+O2和带1个负电荷的体系(Ti/na+O2)-的情况.详细分析了不同反应路径的结合能和电荷变化的曲线,预测了最佳反应方式.结果表明,垂直接近方式要比水平接近方式更具有优势;体系带一个负电荷(Ti/na+O2)-有利于金属与O2的结合.同时,计算结果表明在Ti+O2和(Ti+O2)-体系中Ti容易与单态的O2结合;在中性体系中na也容易与单态O2结合,而在(na+O2)-体系中na与三态O2的结合更稳定.在CCSD(T)/6-311++G(3df)//MP2/6-311+G(d)水平下,计算了Ti+O2和(Ti+O2)-的反应势能面.
