According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

The affected factors to the whisht intensity of pipeline is analysed in two aspects: defectiveness and non. In the non-defectiveness aspect, the tranversing pipeline is considered as thin-wall container, and the annulus stress emerged from inner pressure as main stress on base of stress influence colligated with temperature and inner pressure, then amends it with the axis orientation stress, with the 4th intensity theory, we can calculate the whisht intensity of river tranversing oil pipeline.
