In this paper, it is proved that any couple of matrices over a principal ideal domain (or PID) have a right greatest common divisor and any couple of nonsingular matrices have a left least common multiple, and also, any nonsingular and irreversible matrix over a PID can be expressed as product of finite number of prime matrices.

In order to reduce multiplicative operation rates effectively, three DDC structures based on poly-phase filter have been presented in this paper, which are called respectively the postpositional mixer structure, the least common multiple structure and the double frequency conversion structure.
为了有效降低数字下变频器中的乘法速率,在多相滤波的基础上,提出了3种宽带数字下变频器结构,分别是混频器后置结构、最小公倍数结构和二次变频结构。

补充资料：左忠毅公逸事
散文篇名。清代方苞作。记述明末东林党人左光斗(谥忠毅)受宦官魏忠贤迫害，下狱受刑，其学生史可法入狱探望，左对他寄予希望等史实。通过史可法之口赞颂左光斗“肺肝皆铁石所铸造”。文字遒劲有力。
