两对称

It can obtain a gain of 4.5dB in channel of Gauss and 9.5dB in channel of Rice. Additionally, performance of bit error rate of component code with SM64QAM and HMsym64QAM is tested. It is concluded that the multilevel coding scheme has specific property of unequal error protection.

另外通过仿真采用标准64QAM调制和对称分级64QAM调制两种调制方式的多级编码方案的各分量码的误码性能，可以看出多级编码方案具有不等差错保护的特性。

Also known as asymmetric cryptography, solves the key exchange problem by defining an algorithm which uses two keys, each of which may be used to encrypt a message.

注释 ：公钥加密也称为"非对称加密"，它解决了 key 交换的问题，它使用两个不同的 key ，其中的任何一个都可以用于加密消息。

The first writer of this paper designs the two-side electronic extensometer, which also has two edges but it can be fastened on two symmetric sides of the tensile specimen.

设计的双侧电子引伸计，只用两个刀刃而能测得试样的对称双侧变形的平均值，这样便扣除了弯曲变形的影响而得到了纯粹拉伸伸长。

Placement: before maturity one eye migrates,so that in an adult flatfish both eyes are on the same side of the head.

在一条成年比目鱼身上显著存在的诸多不对称特征中，最为吸人注目的是眼睛的摆位：在成年之前，一只眼睛发生移动，因此在成年比目鱼身上，两只眼睛均位于头部的同一侧面。

Most striking/among the many asymmetries evident in an adult flatfish/is eye placement: before maturity one eye migrates, so that in an adult flatfish both eyes are on the same side of the head.

/在很多的成年比目鱼所表现出来的不对称中/，眼睛的位置是最引人注目的：在成熟以前一个眼睛迁移了，以致于在一个成年鱼的身上，两只眼睛都在身体的同一侧。

Most striking among the many asymmetries evident in an adult flatfish is eye placement: before maturity one eye migrates,so that in an adult flatfish both eyes are on the same side of the head.

在成年比目鱼中存在着许多不对称的地方，最惊人的是眼睛的位置：在成年之前，有一只眼睛会移动，所以成年后两只眼睛都在头部的同一侧。
