The anodic oxidation reactions of borohydride ion involves a novel and complex reaction system of three hydrogen valence states: protide H(superscript --protium H(superscript 0*-proton H(superscript +.

In this dissertation, a theorem to describe the relationship between the quotient group Aut/H and the set F_f is presented. And a way to find the elements of F_f that are conjugate to f is proposed. Then we prove that the quotient group Aut/H is isomorphic to S_3, the symmetric group of order 3, and H is a semidirect product group of GL_(m/2)(4) with the classical binary simplex code S_m in the linear case.

本文刻画了商群Aut／H与集合F_f的关系，给出了一个确定集合F_f中那些与f共轭的元素的方法，还证明了在线性情形下，商群Aut／H与3阶对称群S_3是同构的，而且H是GL_(m/2)(4)与经典单形码S_m的一个半直积，并且推关广了Calderbank等人的一个结果。

ISA proposed by Searle doesn't explain the cognitive environment of S and H respectively, thus it cannot explain why S takes round-about way to scold H and how H infers, and so forth.

Searle的间接言语行为理论在阐释间接性话语时忽略了S和H的个人认知语境，不能解释S为什么绕圈子指责H以及H如何推理等问题。

Remember it takes considerable time and distance to reach high speed: if terminal velocity is 180 km/h, it takes 6.1 seconds (151 m) to reach 150 km/h in free fall, while to reach 170 km/h takes 9.1 seconds (283 m).

注意达到这一速度需要相当长的时间和距离：如果终端速度为180km/h的话（这一速度由自由式跳伞员给出），需要6.1秒，151米的自由下落达到150km/h的速度，如果达到170km/h需要9.1秒，283米的自由下落。

The design of output feedback H(subscript ∞) controllers is discussed for nonlinear discrete singular systems. First of all, by means of generalized Lyapunov function and linear matrix inequalities, zero solution E-asymptotically stable is studied for the system, a sufficient condition is given such that the system is zero solution E-asymptotically stable and a H(subscript ∞) norm constraint. And the output feedback H(subscript ∞) controller is designed to guarantee the performance of the resulting closed-loop system.
