    配套移動噴灌動力車，組成移動或半固定噴灌機組，利用各種水源（井、渠、河、池、湖、溏）對大小地塊進行噴灌。
  2. The boundary layer can indicate the comprehensive influences of oil reservoirs, the physical properties ( reservoir porosity, permeability, fluid viscosity and its composition ) of inside fluids and development conditions such as pressure gradient : the layer thickness reduces with the rise of capillary radius ; when capillary radius is fixed, the thickness increases with viscosity rise ; the more polarity composition content is, the more obvious the absorption, the thicker the boundary layer, more and more obvious the characteristics of non - darcy filtration

    邊界層反映了儲層、流體物性條件（儲層孔隙度、滲透率、流體粘度、組分）和開發條件（壓力梯度）的綜合影響，認為邊界層厚度隨著毛管半徑的增大而減小；在毛管半徑相同的情況下，邊界層厚度隨壓力梯度的增大而減小，最後達到一個臨界值；毛管半徑一定時，邊界層厚度隨粘度增加而增大；極性組分含量越大，吸附越明顯，邊界層厚度越大；邊界層厚度越大，非達西滲流特徵越明顯。
  3. Root distribution and canopy structure parameters of s. godejevii in different sandy land habitats ( semi - fixed sand dunes, fixed sand dunes and inter - dunes low land ), as well as species composition and their frequency in the herb layer of the scrubs, were compared the results were as follows : the population hi the semi - fixed sand dunes had the most developed root systems, followed by he population in the fixed sand dunes, and that hi the inter - dunes low land was the last

    為了更有效地利用這一重要植物資源，本文對分佈於渾善達克沙地三種不同沙地生境（半固定沙丘、固定沙丘、丘間低地）黃柳灌叢的根系分佈，冠層特徵進行了研究，同時測定了灌叢下草本層植物種類組成及頻度，結果表明：半固定沙丘上的黃柳根系最發達（根系分佈深，數量大） ，固定沙丘的黃柳明顯不及前者，而丘間低地的黃柳根系最不發達。
  4. Based on analyzing sintering and infiltration processes, the effect of infiltration temperature on microstructure and properties of the material was studied when the ratio of w - cr, the porosity of green compact and the sintering process of w - cr skeleton were fixed. the differences of microstructure and properties of the composites with different composition were investigated by same sintering and infiltration processes. the composites were prepared in h2, n2, ar and vacuum conditions respectively

    基於對wcr cu復合材料的燒結和熔滲過程的分析，研究了cr - w配比、壓坯緊實率、骨架燒結工藝相同的情況下，不同熔滲溫度對材料的組織形貌和性能的影響；研究了燒結-熔滲工藝相同的情況下，不同配比對材料組織和性能的影響；研究了h _ 2 、 n _ 2 、 ar和真空四種燒結氣氛下材料組織和性能的變化。
  5. The cause of mine disaster lies in insufficient preparation system of the mine disaster governance, so the key countermeasures to govern mine disaster is building the composition of preparation of the mine disaster governance on the basis of 3r, which includes readiness, responsiveness and relevancy, and setting up the fixed preparation system of the mine disaster governance
