The result shows, this model can predict PM10 concentration value on the street of Nanjing basically, at a little windy state, the first linear relevant equation of predicted value is y =1.0006x, replies the coefficient correlation and reaches 0.9636; In the quiet wind state, STREET BOX model predicted value is lower than the surveying value.

结果显示，该模型基本可以预测南京街道上PM10浓度值，小风状态时，模型的预测值与街道实测值的一元线性相关方程为y=1.0006x，复相关系数达到0.9636；在静风状态时，STREET BOX模型预测值低于实测值。

During the New Moon (the 1st of a lunar month) and the Full Moon (the 15th of a lunar month) when the Earth, Moon, and Sun lie in a straight line, the solar and the lunar tides overlap and the sea-level pressure is lower than the mean at the Airport, because the tide-producing force induced by the Sun and Moon reaches maximum. On the other hand, during the First Quarter (the 7th day of a lunar month) and the Last Quarter (the 21st of a lunar month) the Sun-Earth's and the Moon-Earth's relative positions are perpendicular to each other with respect to Earth, the solar and the lunar tides interfere mutually, the Airport sea-level pressure is greater than the annual mean due to the tide-producing force reaching minimum.

松山机场在朔望月里，每逢阴历朔日或望日，受太阳与月球之引潮力(Tide-producing force)方向一致，太阳潮和太阴潮重叠影响，其全日和逐时平均海平面气压比年平均为低；而每逢上弦和下弦时，日地与月地的相对位置成直角，太阴潮和太阳潮相干扰，其全日和逐时平均海平面气压则比全年平均为高。

I. e δ^13C and δ^18O ratioes obviously vary with height, generally, the heavier/lighter isotope ratio is higher at the upper/bottom layer of canopy; and temporally,δ^13C and δ^18O ratioes are highest from afternoon to sunset, and lower before dawn, with the lowest ratio at the time when air is stable and the CO2 from the respiration of vegetation and soil reaches the biggest accumulation amount.

主要表现在δ^13C和δ^18O在冠层内具有明显的垂直变化趋势，冠层上部重同位素含量较高，而底部含量较低。从时间变化看，δ^13C和δ^18O在午后到日落具有较高的水平，而凌晨，δ^13C和δ^18O较低。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.

结果表明：塑性区和动态静止层的晶粒在热和力作用下发生动态再结晶形成细小的等轴晶，热影响区的晶粒在摩擦热作用下长大变粗；搅拌头旋转速度为2 500 r/min，焊接时间为12 s时，可以获得力学性能较好的焊点，焊点的剪切强度达到9.24 kN；焊点的剪切强度随搅拌头旋转速度的增大而增大，随焊接时间的延长先增大后减小；塑性区的显微硬度较高，但略小于母材，接头显微硬度的最小值分布在热影响区；焊点热输入量较多时，接头为Ⅰ型断裂，焊点的剪切强度较高；焊点热输入量较少时，接头为Ⅱ型断裂，焊点的强度较低。
