  1. The result of experimentation on coupling effect of water and fertilizers on spring corn in the three gorges reservoir area indicate that water stresslead the effect low of highness and lai, and the most effect is made in shooting stage ; it has a significant positive correlation between the yield of corn and biomass, and hasn ' t none significant positive correlation between the yield of corn and the weight of roots ; the coupling effect of water and n is significant, but the coupling effect of water and k is not significant, the maximum yield of corn condition fitting - water and medium n, corn absorbs n has a threshold value during the growth, and using superfluous n is able to prick up soil drought and crop drought ; water is the leading factor which effects the yield of corn, next is n and k

    摘要三峽庫區春玉米盆栽水肥耦合試驗研究結果表明，水分脅迫導致玉米株高和葉面積指數降低，以拔節期受到影響最大；玉米產量與生物量呈顯著正相關關系，產量與根重無顯著正相關關系；水氮耦合效應顯著，適宜水分和中氮處理下玉米的產量最高，玉米生長發育對氮肥的吸收存在一定的閾值，過多施用氮肥會加劇土壤乾旱和作物乾旱，水和鉀耦合效應對玉米產量影響不顯著；水分是影響玉米產量的主導因素，其次是氮效應和鉀效應。
  2. Either the boron nitride ( bn ) thin films with different cubic phase content were deposited on n - type si ( 111 ) and fused silica substrates by radio frequency ( rf ) sputtering using two - stage deposition process. the films were characterized by fourier transform infrared ( ftir ) spectroscopy. the transmittance te ( ) and reflectance re ( ) were obtained as a function of incident photo wavelengths and the thickness of films was measured by alpha - step. the absorption coefficient was calculated from te ( ) and re ( ). the optical band gap ( eg ) of the films was determined by effective medium form of formula containing eg

    本文還研究了立方相含量與光學帶隙的關系，在n型si （ 111 ）片和熔融石英片上沉積出不同體積分數的立方氮化硼薄膜，薄膜的成分由傅立葉紅外吸收譜標識；用紫外-可見分光光度計測量了沉積在石英片上的bn薄膜的透射光譜te （ ）和反射光譜re （ ） ，薄膜的厚度用臺階儀測得。
  3. In field study, the expenment on nitrogen transport and transformation in soils with different irrigation ( with both ground water and sewage effluent ) and fertilization levels has been conducted. with considenng the n - uptake, nitrification and demtrification processes, a model for describing no2 - - n transport and transformation in unsaturated soil has been applied. results show that, the n03 + - n accumulating in soil is contributed more by fertilization but lees by irrigation with sewage effluent, and the model can be used to simulate no3 - - n transport in soils

    在室外進行了不同清污水灌水量與施肥條件下氮素遷移轉化試驗，同時進行了考慮根系吸收，硝化和反硝化的田間非飽和no _ 3 ~ - ? n遷移轉化模型的數值模擬，研究結果表明與施肥相比，污水灌溉對土壤中no _ 3 ~ - ? n累積的貢獻較小，所建立模型可用於模擬no _ 3 ~ - ? n在土壤中的遷移。
  4. Through determination of the infinite relative volatility for ethane / ethylene by means of gas stripping method, the ability of the cuprous halide amine to separate ethane / ethylene is evaluated and the factors influencing the stability of the cuprous halide amine such as the basicity of ligand, diluters, ratios are studied

    摘要通過測定乙烯乙烷在含氮基團絡合亞銅體系中的無限稀釋相對揮發度，研究了基團堿度、配比數及稀釋劑對吸收劑選擇能力和穩定性的影響。
  5. Zero - value coefficients about interaction of water and temperature is put forward, zerovalue phenomenon about interaction of water and temperature and energy character that moisture vaporizes, ammonia volatilizes, millet seeding grows and it absorbs nitrogen are brought to light

    在所研究各種體系水熱耦合效應基礎上，提出了水熱效應零值參數概念，揭示了水熱耦合效應零值現象及水熱耦合作用下土壤水分蒸發，肥料氮揮發和穀苗生長及氮素吸收的能量特徵。
