If for any two t-edge sequences whose initial edges have non-empty intersection, there exists an automorphism of H mapping one to the other, then H is called locally weakly t-transitive.

若对於任二个 t-线序列，其第一个元素的交集并非空集合时，均存在一个 H 的自同构函数将其中一个对应到另外一个，则 H 称为局部弱 t-递移。

Recently , the classical Riesz representation theorem on Hilbert spaces has been generalized onto complete random inner product modules ,in this paper the classical Friedrichs theorem on Hilbert spaces is generalized onto complete random inner product modules.

最近，经典的Riesz 表示定理已经被推广到完备随机内积模上，在此基础上本文将Hilbert 空间上经典的Friedrichs 定理推广到完备随机内积模上。首先，证明完备随机内积模上任一正Her2 mite 型惟一地对应一个正自共轭算子。

Based on accurate step motor system parameters, the state equations describing step motor dynamic characteristics are set up. The operation of the self synchronization closed loop control system is simulated on computer. In the research the principle analysis and system design have been done about self synchronization closed loop operation. The relation between rotating EMF and the rotor position of the step motor is discussed. Through detecting the zero value of rotating EMF the rotor position of the step motor is indirectly obtained.
