Maleic rosin has been added to the surface of wood flour in the form of monoester, i.e., the formation of esterified wood flour bearing a pendent carboxylic group. The rheological study showed that the complex viscosity η(superscript *, storage modulus and loss modulus of WF-HDPE composites decreased firstly and increased afterward and declined lastly as the dosage of maleic rosin increased, however, the viscosity of the composite melts decreased as a whole. After the modification of wood flour, the rheological properties of composite melts were improved markedly. According to the mechanical test it was indicated that, by proper treatment of wood flour with maleic rosin, the tensile strength and flexural strength of WF-HDPE increased obviously.

WF-HDPE流变学研究表明：复合材料的复合黏度η(上标*、储能模量和损耗模量随马来松香用量的增加先减小后增大最后减小，但体系的黏度和模量总体呈下降趋势，木粉经马来松香改性后复合熔体的流变性能显著改善，这不仅有利于提高复合材料的成型加工效率，而且适当的马来松香处理也能够提高复合材料的拉伸强度和弯曲强度，后者被静态力学试验结果所证实。

In the third area, Pb2 is gradually supersaturated in solution with the increase of pH value, so the Pb2 is deposited as sediment. As a result, the processing of wulfenite leaching by sodium hydroxide is carried out. Additionally, feasibility of the processing of wulfenite leaching by sodium hydroxide is proved, but Pb(superscript 2+) reacts with hydroxyl to form complexes which is leached into solutions. So removing the complexes lead from solution is needed.

通过对Pb-Mo-H2O系的热力学分析，苛性钠分解彩钼铅矿在一定的pH值下是可行的，但在碱分解过程中Pb(上标 2+)与羟基形成了配合物，主要是以Pb3的形式存在而大量进入溶液，因此，尚需进一步除铅。

By using properties of quasi-regular semigroups and left central idempotents, some statements are proved. Let S be a quasi-right semigroup, then (1) S is a quasi-completely regular semigroup;(2) RegS is a completely regular semigroup;(3) R(superscript *) is the smallest semilattice congruence on S;(4) Each R-class T(subscript α) on RegS is a right group;(5) T(subscript α)G(subscript α)×E(subscript α), where G(subscript α) is a group, E(subscript α) is a right zero semigroup.

利用拟正则半群和左中心幂等元的性质，证明了S为拟右半群时，(1) S为拟完全正则半群；(2) RegS为完全正则半群；(3) R为S上的最小半格同余；(4) RegS上的每个R-类T为右群；(5) TG×E，其中G为群，E为右零半群。

The process was controlled by diffusion and irreversible. Pb(superscript 2+) transferred from water to acetylacetone to form Pb2 with dithizone.

实验证明，该过程是受扩散控制的不可逆过程，Pb(上标 2+)由水相转移到有机相中，与双硫腙形成络合物Pb2。

The density functional theory B3LYP/6-31G(superscript * was used to study 9 aconitine analogs and the relationship between structure and toxicity was discussed.
