The experimental results show that microwave sintering promotes the densification of green compacts with higher heating rate and reduced sintering cycle. The sintered relative density of 99.8% can be achieved during microwave processing under appropriate conditions. In addition, microwave sintering improves the uniformity and homogenization of W grain size, and yet leads to growth of W grain. Fe sintering aid degrades the microstructure uniformity and further coarsens W grains. The present investigation demonstrates the feasibility of applying microwave sintering technique to consolidate W-Cu composites and its promising outlook in reducing production cycle and cost.

Through the comparative analysis of the earth pressure calculated by the different calculation methods, it is known that when the earth pressure behind the abutment of the integral abutment bridge under the action of rising temperatures is calculated, it is not proper to use the m method to calculate the resistance coefficients of the abutment back wall and column earth while the resistance coefficient of the abutment back wall earth can be calculated by the Broms method. It is proper that the resistance coefficients of the earth of the abutment and pier piles should be considered by the p-y curve.

Its high-capacity and strong-acid-resistance were proved. In the acid condition, the adsorption efficiency to acide green 6B and direct fast yellow RL reached above 90%. Through the adsorption rate curve on adsorption behavior of the three dyes, they were all according with pseudo-secondary adsorption rate curve. The rate constant of adsorption increased with increasing temperature. Through the adsorption isotherm of the three dyes, acide green 6B and direct fast yellow RL were according with Langmuir equation, while disperse blue 56 was according with Freundlich equation. The adsorption behavior was an endothermic process. Entropy was increasing during the adsorption. So raising temperature was in favor of adsorption.

But along with the social economy development, the vegetables consumption quantity is daily increased, the great scale of the greenhouse vegetables production is higher and higher day after day and a special reason is benefit actuation. It emerges one batch of vegetables types relatively sole specialized production base one after another, which causes the original cropping system to disintegrate objectively, the farmer who is engaged to run some specific vegetables production is increased day by day, the vegetables type are restricted frequently by the high production and economic efficiency fruit vegetables, the tendency of specialized production is suddenly revealed day after day, finally is causes the soil environment to worsen, the vegetables plant disease to be serious, the output to reduce, the quality and the series barrier of continuous copings to occur and the facility vegetables production further development to be cut down.
但随着社会经济的发展,蔬菜消费量的日益增加,温室蔬菜规模化生产日渐升温,加上效益驱动等原因,相继涌现出一批蔬菜种类相对单一的专业生产基地,客观上导致原有耕作制度瓦解,从事某一特定蔬菜生产的农民日益增多,蔬菜种类常常局限于生产经济效益高的果菜类,专业化生产趋势日渐突显,结果导致土壤环境恶化、蔬菜病虫害严重、产量降低、品质下降等一系列连作障碍的发生,严重威胁着设施蔬菜生产的进一步发展。
