通过对地表类型影响大气的机制分析，表明随着模拟时间的增加，地表的影响可能逐渐减弱，这显示出处于稳定状态的大气，可以抑制地表产生的这种扰动作用，表现出大气对地表类型改变产生扰动的一种自我恢复能力。

The semiconductor nanocrystalline surface is modified by using organic overlay method. As an organic overlay,-methacrylic restrains the reuniter between the grains in the latter process. Furthermore, it can combine with empty bond of atom at grain surface state and eliminate the surface state.

应用有机包覆的方法对纳米颗粒进行了表面修饰，作为包覆剂的α-甲基丙烯酸有效抑制了后处理工艺中纳米颗粒间的团聚现象，在纳米颗粒表面形成帽层，并与粒子表面态的原子悬键进行配位，这对消除表面态是非常有益的。

Accordingly three DNA computing models, the solution-based model, surface-based model and the combination of solution and surface-based model, were presented to solve 0-1 programming problem in the study. The advantages of massive parallelism, high-density storage and potential robotization of solution-based and surface-based model were well embodied and their shortages such as timewasting operations and less massive parallelism were also avoided by all means in these models.

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5. The borate structure and semipolar bond were studied in different pH by infrared spectrum .It indicated that N_xB and N_xOB have not semipolar bond at pH

4、25℃，N_xB系列都有较低的表面张力，并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN／m低，且临界胶束浓度为4.1×10~(-5)mol／L，也比LAS低，且随着NaCl浓度的增加而略有下降，比较N_(12)B和N_(16)B，由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低，由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。

In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.
