Regional variation difference was very large with more ice in the eastern Antarctic, obviously less ice in the west Antarctic, both sides of the Antarctic Peninsula, especially in the Weddell Sea and the Bellingshausen Sea. The sea ice variation trend in the eastern and western Antarctic is always in opposite phase.

研究表明20世纪70年代后期是多冰期；80年代是少冰期；90年代南极海冰属于上升趋势，后期偏多，区域性变化差别大，东南极海冰偏多，西南极海冰即南极半岛两侧尤其是威德尔海区和别林斯高晋海的冰明显偏少。

Based on the method of multi-objective fuzzy optimization and the overhead traveling crane design, a mathematical model of fuzzy optimization for main box beam section is established. A fuzzy goal anthology is constructed. The fuzziness of multi-objective function and constraints is defined. The transformation of the fuzzy constraints set to normal constraints set in real number domain is realized by applying optimal level cut set method. The optimal solution and optimal constraint value of sub-objective function in the feasible field are found using the genetic algorithms.

应用多目标模糊优化方法，以工程设计中桥式起重机箱形主梁设计为实例，建立了桥式起重机箱形主梁多目标模糊优化设计的数学模型，构造了模糊目标集，确定了多目标函数的模糊性和约束的模糊性，并应用最优水平截集法实现了模糊约束到实数论域上的集合转换，从而用遗传算法寻求到子目标函数在可行域空间的最优解和约束最优值。

The various multiuser detection schemes are studied in the next chapter, considering the deficiency of traditional linear detection algorithm, this dissertation proposed a nonlinear multiuser detection algorithm, because it used the high order statistic property, its beneficial is proved by the simulation results.

第六章介绍了多用户情况下的各种检测方法，针对以往WCDMA线性多用户检测方法的不足，本文提出了非线性多用户检测方法，它充分利用了用户信息的高阶统计特性，在性能方面有了很大的提高。仿真结果证明了它的有效性和优越性。

For the multi solution and multi goal engineering problem,gray system theory can be used to establish a Europian space,oriented at each goal.

对于多方案、多状态、多目标的工程问题，可以应用灰色系统理论建立一个以各目标为坐标轴的欧氏空间，并在此空间内定义一个灰靶，将由状态和方案组成的局势，在目标上的观测值向效果空间进行映射，以求得最优方案。

Specifically, without demanding more prior information than that for the conventional matched filter, the proposed algorithm integrates space-time coding with channel estimation, achieving the MAI suppression by projecting the received signal onto the orthogonal complement of the estimated subspace.

该算法结合空时编码技术，在对多天线信道进行估计的基础上，通过对干扰子空间的补进行正交投影，实现了抑制多址干扰的空时多用户检测。

An algorithm for constructing a class of symmetric-antisymmetric orthogonal refinable functions with multiplicity 2r is presented.

给出一类重数为2r的正交对称-反对称多小波的构造算法，即对任给长度为2N的对称-反对称正交多小波，通过本文所给的构造算法可以得到长度为2N+1的对称和反对称多小波。

Multipath is the main character of the mobile communication system. Multipath signal of the target user turn out to be the ISI of the main path signal, multipath signal of the other users cause severe MAI since the orthonormality among the spreading codes is destroyed.

多径干扰是移动通信系统中的常见干扰，目标用户的多径信号对主路径信号引入了码间干扰，其它用户的非同步路径信号由于破坏了扩频序列的正交特性而导致了强的多址干扰。
