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。

Single component and multi\|component of iron system colloidal catalyst \Ali\|Bu\-3CH\-2CHCH\-2Cl\ were mixed by different ratios in hydrogenated gasoline medium at 25℃.This paper studied the relationship between the nonaqueous systematic electroconductivity and the concentration of catalyst components.In combination with Tyndall effect,polymerization experimental results,Ali\|Bu\-3 existed in associated state and dissociated into ionpair.The reaction between Ali\|Bu\-3 and Fenaph\-2 was the main reaction which formed colloidal core.Ali\|Bu\-3 reacted on CH\-2CHCH\-2Cl and Ali\|Bu\-2Cl was yielded which joined the formation of active center on the surface of colloidal core.The excessive Ali\|Bu\-3 was dissociated into ionpair which formed double electrode layer,and the double electrode layer kept the colloidal particles relatively stable.

研究了在25℃加氢汽油介质中，铁系胶体催化剂［Fenaph2Ali-Bu3―CH2==CHCH2Cl］单组分、多组分按不同配比混合，非水体系电导率与浓度的关系，结合Tyndall效应，聚合实验结果，得出Ali-Bu3以缔合状态存在并解离成离子对它同环烷酸亚铁的作用是形成胶核的主要反应，与氯丙烯反应生成的氯化异丁基铝，在胶核表面参与形成活性中心由过量Ali-Bu3解离的离子对形成的双电层结构，使胶粒保持相对稳定。

The further analysis indicated that the double gene transgenic petunia possessed stronger capacity to take up liquid formaldehyde than the control and the single gene, DAS or DAK, transgenic plants. This resuLt suggests that the expressed DAS and DAK might establish aHCHO-fixation pathway which functions in the double gene transgenic plants.

对液体甲醛吸收速率测定结果表明转DAS、DAK双基因的矮牵牛对甲醛的吸收速率明显快于对照植物和转单个基因DAS或DAK的植物，说明转基因表达产生的DAS、DAK可能构成一条甲醛固定途径，在转双基因植物中发挥作用。
