Using the directional derivative formula, the governing equation is discreted in the physical domain in which a nonorthogonal grid system is used. Two kinds of AF2 schemes, i. e. AF2-plane relaxation and full implicit AF2, for the TSD equation are proposed. Numerical results show that the full implicit AF2 scheme converges faster than AF2plane relaxation scheme. For the rectangular wing and swept wing, the results of the present method are compared with FP results, and the agreement is good.

When the molar fraction of SnO2 is 83%, the main component of the coating isO2 solid solution with rutile structure. When the molar fraction of SnO2 is 44%, the main components of coating are theO2 solid solution with rutile structure andO2 solid solution with fluorite structure. When the molar fraction of SnO2 is 17%, the main component of the coating isO2 solid solution with fluorite structure. Annealed at higher temperature than 450 ℃, CeO2 is found in the coating containing 83%Sn, and there is not SnO2 in the coating containing 83%Ce, which suggests that fluoriteO2 has higher thermal stability than rutileO2. When the molar fraction of SnO2 increases, the dispensability of the coatings is improved greatly.

结果表明：通过控制制备条件可获得具有纳米结构的钛阳极涂层；当Sn的摩尔分数为83%时，涂层主要为金红石相的O2固溶体；当Sn的摩尔分数为44%时，涂层中金红石相O2固溶体和萤石结构的O2固溶体共存；当Sn的摩尔分数为17%时，涂层由萤石结构的O2固溶体组成；高于450 ℃退火时，含83%Sn的涂层中出现CeO2相，而在含83%Ce的涂层中没有出现SnO2相，表明在相同的溶质浓度下，萤石结构的O2固溶体比锡基金红石相O2固溶体具有更好的热稳定性；而涂层中的SnO2具有明显改善涂层分散性的作用。

Through similar simulation test of block top-coal drawing, the influence of coal block size and block position in top coal on the recovery ratio and drawing manner is studied. It is found that the drawing manner has the different adaptation to the top coal which has different block distribution. The caving capacity is mainly decided by the block size. The top-coal which has layer difference of block with the same size has different recovery ratio. It is shown, that, to the given top-coal blocks, the recovery ratio of uniformly mixed blocks is maximal in the manner of drawing at interval of one support.

研究表明，顶煤块体大小是影响顶煤回收效果的主要因素，在顶煤块径一定的条件下，块体层位分布不同是造成顶煤回收率差异的主要原因，研究表明各级块度均匀混合时顶煤回收效果最好，块度从下向上增大分布次之，大块为中位顶煤时回收效果最差；各种放煤方式的适应性不同，各级块度均匀混合的顶煤适合用间隔放煤；块度从下向上增大适合用顺序放煤；大块在顶煤中位分布时，中硬煤以下适合用间隔放煤，硬煤应采用顺序放煤方式。

Eccles's own empirical study of residential construction in Massachusetts shows not only that subcontracting relationships are long term in nature but also that it is very rare for a general contractor to employ more than two or three subcontractors in a given trade, whatever number of projects is handled in the course of a year 1981, pp.

Laboratory experiments were carried out to study the survival and development of the Harmonia axyridis feeding on Chaito phorus popleti on high insect-resisitance hybrid poplar 741(Pb29) and medium insect-resisitance hybrid poplar 741(Pbl7).The API 741 poplar was used as control.The mortality and development during immature period,adult,baby mass.eclosion and sex ratio of H. axyridis were measured.The results showed that:to contrast The API 741, Chaito phorus popleti on Pbl7 and Pb29 has no significantly impacts on eclosion,pupation, ecdysis,mortality of immature period and pupa stage;Although every development stage of ladybeetles were not affected to ,the pupal duration of ladybeetles was lowered than the control;The body mass,eclosion and sex ratio have no significant difference.

通过利用节肢动物群落及各个亚群落的物种丰富度、个体数、均匀度和优势集中性对多样性指数进行通径分析，表明了高抗Pb29和CK节肢动物群落及各个亚群落多样性指数与均匀度和优势集中性的相关系数最高，与其物种个体数关系最为不密切：对各组分进行通径分析均表明的多样性提高是建立在降低优势集中性和增加均匀度指数的基础上的，而且以优势集中性的直接作用效果较为显著。
