This text is mainly about the analysis of the palindromes of Y chromosome. We mainly used DOTTER program for detailed comparison of two sequences to obtain these results. The main contents are as follows:Chapter one mainly introduces the whole characteristics of human Y chromosome;Chapter two mainly describes the characteristics, functions and recombination modes of the palindromes in Y chromosome;Chapter three mainly analyses the symmetries of 8 palindromes of Y chromosome, we find a mechanism of symmetry breaking in P2 palindrome from a detailed analysis;initially introduces other 7 palindromes.

本文主要借助于DOTTER程序对Y染色体的回文序列进行分析，主要内容如下：第一章主要介绍人类Y染色体的整体特征；第二章主要描述Y染色体中回文序列的特征、功能及重组模式；第三章主要是对Y染色体8个回文序列的对称性分析，主要对P2回文进行了详细分析，提出了P2回文的对称性发生破缺的机理；对其他7个回文进行了初步分析。

Ata small substitution(x=0.04),the perfect of Mn-O plane and the double exchange in-teraction are destroyed,which result in the decreasing of the transition temperatureof the charge-order state and the melting field within the sample.

在少量的替代下(x＝0.04)，起主要作用的是Mn-O面的破缺和对双交换作用的影响，表现为电荷有序态转变温度和低温下熔化场的下降。

First of all, Chipmunk uses double precision floating point numbers throughout it's calculations by default.

Chipmunk在计算的时候，缺省使用的双精度浮点数。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
