A new symbol-constrained joint source-channel decoding algorithm for VLCs is presented.By constructing double-tree VLCs sources,the propagation-error problem is evidently alleviated.Meanwhile,by applying symbol-constrained method to MAP algorithm,not only the a priori probability of VLCs sources is efficiently utilized,but also the Symbol Error Rate is reduced enormously.

提出了一种新的针对不等长编码信源的符号约束MAP联合译码算法，利用VLCs双树信源的构造方法，有效地抑制了VLCs的错误扩散；同时，通过将"符号约束"的思想应用于最大后验概率译码算法，不仅充分利用了信源先验信息，而且极大地降低了误符号率。

It can also reduce the handover frequency, hold the continuity of the correspondence and make the load of MAP balance when handovers occur.

这个模型是通过使用非固定的MAP域管理，针对单一移动节点的逻辑管理域，解决移动节点在域间切换和域内切换时的通信延时问题以达到降低切换行为的发生频率、保持切换发生时通信的连续性、使MAP负载均衡等目的。

Methods: Based on B-cell epitope 82~93, a multiple antigenic peptide system was synthesized as immunogen and C-57BL/6 mice were divided into 3 groups randomly. MAP group (n=5) referred to that C-57BL/6 mice were immunised with the immunogen and the polyclonal anti-serum was produced. The polyclonal antibody was identified by using an ELISA assay.

将C-57BL/6小鼠随机分为对照组、MAP组、人参总皂苷组，MAP组在预测MAGE-12的B细胞表位序列为QSDEGSSNEEQE(82-93)的基础上，采用4分枝多重抗原肽结构设计合成抗原肽，免疫C-57BL/6小鼠，产生多克隆抗体，应用ELISA实验检测多克隆抗体是否为人的抗原肽的特异性抗体。

Methods:The self-made potassium chloride monopha- sic action potential recording electrodes(KCI-MAP elec- trodes)were pluged into the canine left anterior ventricu- lar wall,where isoprenalinewas administered through the KCI-MAP electrodes to mimic the increase of local sympathetic nervous tension,monophasic action potentialof the three layers(endocardium,mid-myoeardium and epicardium)at left anterior ventricular wall were re- corded simultaneously before and after Iso been administered.

方法经自制跨室壁氯化钾单相动作电位记录电极(KC1-MAP电极)于左心室前壁局部给予异丙肾上腺素模拟局部交感神经张力增加，记录给药前后三层心肌的单向动作电位，分析动作电位时程、图形特征和跨室壁复极离散度的变化，观察VT的诱发情况和VT发作时室壁激动顺序。

Mercator is the type of projection you see used on Live maps and Google maps, but as many often mistakenly thinks, they do NOT use WGS84 for the projected map, although WGS84 is used when you directly input longitude/latitude values using their API.

Live Map和Google Map都使用墨卡托投影，但并不像人们认为的那样他们使用WGS84基准面，虽然你在他们的API中输入的值是WGS84下的值。【译注：原因是WGS84基准面是基于椭球面的，而LiveMap和GoogleMap使用的是球面。另外，YahooMap使用的是等距圆柱投影。
