When constructing a parity-check matrix, PEG can maximize the girth length, thus lowering error-floor, while quasi-cyclic structure bears other advantages.

在校验矩阵构造方面，PEG的构造方法在度约束条件下能最大化环长，从而降低误码平层。同时准循环码在结构化方面也有很多优点。

We measured the fish and used the GT length and girth formula to get the weight, and then also checked this against a measured weight on our scales.

我们测量的鱼，并用燃气轮机的长度和周长计算公式得到的重量，然后又核对，对我们这个尺度衡量的重量。
