But the traditional recorder has a lot of shortages;complicated structure,simple function,frequently addinq ink and paper changed etc. In addition,the data are registered in paper with the shape of a curve,so it is not convenient to saving,processing and editing of a file. The paperless recording instrument will initiated an epoch,because it has integrated the electronic technology,cyber- technique and network communication technology.

In this paper, new classes of linear block codes over finite fields of the algebraicinteger ring of quadratic number fields Qd~(1/2 modulo irreducible elements with norm p or p~2 are presented. These codes can correct one error which takes from the cyclic subgroup of the multiplicative group of the finite fields. The results presented in this paper extend the corresponding results of previous papers.

在处理适用于二维信号的线性分组码时，我们考虑类数为1的有理数域二次扩域Qd~(1/2的代数整数环，利用范数为p或p~2的不可约元构造有限域，给出剩余类域的一组完全陪集代表元系，从而构造出一类有限域上的线性分组码，当错误取值于有限域乘法群的一个循环子群时，所得到的适用于二维信号的线性分组码可以纠单个错，推广了文[14-16]的结果。

In this paper, a performance index, which is used to evaluate the operating uniformity of multi-cyclinder engine, is presented based on the fact that the fluctuation of gas pressure in the expansion stroke cyclinder leads to the fluctuation of instantaneous angular velocity. The value IP is propotional to the fluctuation of instantaneous angular acceleration. Fuzzy diagnostic index for misfire fault is introduced and investigated also in this paper.

根据多缸发动机曲轴瞬时转速波动不均匀性主要由缸内循环气体压力波动不均匀性引起这一基本事实，以曲轴瞬时转速的实时检测为基础，在一个工作循环内按着火顺序将作功冲程中瞬时角加速度的波动作为评定各缸工作不均匀性的指标，将所得IP模糊化用于多缸机的故障诊断也作了初步的探讨。
