小麦冬春抗旱保墒技术

一、冬灌；“小麦不冻灌，受冻又遭旱”、“麦苗灌冬水，春后不噘嘴”实践表明，无论北方冬麦区，还是江淮冬麦区，冬季和早春的低温干旱气候条件，是小麦死苗的重要原因。冬灌的好处甚多：1．蓄水保墒，冬水春用。在“春雨贵如油”和“冬春风似狼”的地区，冬灌能蓄水于耕层，可起到冬水看用和风掀亩的作用；又以水调温，甚弱冻冒．寒要啥用，气温反／北风烈，天寒地冻，给小麦越冬带来提大团推，这以要来提高地盘，而去准以水调温，以水稳温，在提大程度上可直弱冻冒；3．层实立团，杜绝“吊百”，冬水留清碎明些暗回拉，闻公麦苗露报另苗…

管内覆丝网强化对流换热及阻力特性的实验研究

通过实验对管内覆丝网管进行了强迫对流换热和阻力特性研究。结果表明：管内覆丝网使换热明显增强，阻力也相应增长。菱形丝网对角线距离与平行边距离之比对换热效果有决定作用，丝网厚度对换热的影响比较小，而丝网网格的大小对换热几乎没有影响，在相同的泵功率和几何条件下，换热系数最大增加２１％。

LASER CLADDED TiCN COATINGS ON THE SURFACE OF TTTANIUM

Laser cladded coatings of TiCN were produced on the surface of titanium. To obtain the optimal techniques, several conditions were tested by varying the laser scanning rate. The choice of shielding gas was also studied. The cladded coatings were then evaluated from the surface mechanics point of view based on their microhardness. The microstructure of some interesting samples was investigated by optical micrographs （OM）. The results showed that under the condition of fixed pulse frequency and pulse width, the laser scanning rate and the shielding gas are the main factors influencing the components of coatings. TiCN coatings were decompounded and oxidized during the cladding process in the condition of no shielding gas of N2. X-ray diffraction results indicated that the composite coatings composed of TiCN, TiC, Ti2N, and TiO2 were produced using appropriate techniques. The results indicated that the best condition in terms of the surface microhardness is obtained when the scanning rate is 1.5mm/s, the pulse frequency is 15Hz, the pulse width is 3.0ms, and N2 is chosen as the shielding gas. The microhardness of the composite coatings is about 1331kg · mm^-2, which is about 4 times that of the substrate. The optical micrographs indicated that the cladding zone is made up of TiCN, TiO2 and some interdendritic Ti, but the diffusion zone mainly consists of the dendrites phase, and the cladded depth is about 80μm, which is more than 2 times that of the laser nitrided sample. There were no microcracks or air bubbles in the cladded sample, which was cladded using the above optimal techniques.
