Besides,we investigate the compatibility of the pair,where A is a bounded linear self-adjoint operator on a complex Hilbert space H and S is a closed subspace of H.

此外，对由一个自伴算子A和一个闭子空间S组成的元素对的兼容性进行了研究。

Let A" denote the commutant of a bounded linear operator S on H and R denote the collection of all operators in A" which are compact and upper triangular operators with diagonal sequence being zeros. In this paper, we show that if A"= CI + R, the K_0-group of A" is isomorphic to the integer group.

本文指出若H上的有界线性算子S的换位代数A′=CI+R，其中C是复数域，I是H上的单位算子，R是所有与S可交换的对角线为0的紧上三角有界线性算子的集合，则K_0A′

This paper precisely conducts the special topic research in view of some important technologies of the digitized control module.(1) AC motor control circuit of PAN/TILT is designed ,which speed is controlled by AT89C51 MCU. DC motor control circuit of LENS is designed too.(2) The hardware and software of automatic temperature control is designed, which used in camera protect box without A/D IC. A kind of single wire communication IC is used in the circuit. So, the program is given.(3) A method of video switch without picture shock is discussed in this paper, and 16x8 video switch circuit is designed. AT89C51 can carry out time sequence logical control with the sync signals by request..(4) The module of real-time clock is designed, in which, LCM is used, a kind of three-wire communication IC is used too.

For example: Three series battery pack application, when the initial, A, B, C three single battery for 100% of capacity, but in the long-term use, the batteries have had uneven, resulting in at some point, A 80% of the remaining battery capacity, B Battery of the remaining 40% of capacity, C battery of the remaining 60% capacity; If Charged the three series pack batterys, due to the protection of high voltage, When A is charged 100% full and let the charger closed , B Battery capacity for only 60%, C for 80% of battery capacity and thus give rise to the battery pack inside the battery B and C is not fully charged.

这些不均衡现象不仅会使电池包容量变小，甚至还可能会造成严重的过充电、过放电等安全隐患。让我们来对这两种情况进行仔细分析：首先是针对电池包容量变小的情况；。以三串电池包应用为例，初始时，A、B、C三单体电池都为100%容量，但在长时间的使用下，各电池产生了不均衡，造成在某一时刻，A电池剩余80%容量，B电池剩余40%容量，C电池剩余60%容量；此时对电池包内进行充电，由于过高压保护的作用，当A电池充满100%而使充电器关闭时，B电池容量才为60%，C电池容量为80%，从而出现电池包内B电池和C电池有未充满电现象。
