  1. Recently, the chinese plant protection agencies reported the growing hardships in controlling some field populations of oriental migratory locust with organophosphate ( op ) compounds. up to now there are more than 600 arthropod species with documented resistance to one or more insecticides and / or acaricides since resistance phenomenon was first described in san jose scale to lime - sulfur in washington in 1908. enhanced metabolic detoxification and reduced sensitivity of insecticide target - sites are the two major mechanisms in resistance development, involving three primary metabolic enzymes of esterases, glutathione s - transferases and cytochrome p450 polysubstrate monooxygenases

    代謝抗性是指對殺蟲劑起水解或隔離作用的酶發生改變,從而對殺蟲劑起到解毒作用,昆蟲主要解毒酶系有酯酶、谷胱甘肽- s -轉移酶、細胞色素p450單加氧酶等,這三種酶系任何一種的組成部分發生改變均會引起害蟲抗性的改變;靶標抗性是指由於殺蟲劑作用靶標敏感度降低而產生的抗性。
  2. In this paper, the effects of fly ash, cement, lime, fine sands, foam agent, w / c ratio and additional agent on foamed concrete were studied by experiments, the best combination ratio of fly ash foamed concrete whose density varies from 551kg / m3 to 650kg / m3 was obtained through orthogonal test design, the foam agent quantity and the fly ash quantity effect the fly ash foamed concrete greatly, so the author selected them as independents to establish duality linear regression equations, the equations were quite ideal through the test of model summary r. moreover, the author also did some experiments about the water resistance of magnesium oxychloride cement fly ash foamed concrete, the outcome showed that phosphoric acid has good effect on water resistance, and its appropriate quantity was found

    本文通過試驗研究了粉煤灰、水泥、石灰、細砂、發泡液、水灰比及外加劑對粉煤灰發泡混凝土性能的影響,採用正交設計試驗方法得出了600級粉煤灰發泡混凝土的最佳配合比,同時發現發泡液和粉煤灰摻量對發泡混凝土的影響最為顯著,因此,以二者為自變量建立了二元線性回歸方程,通過全相關系數的檢驗發現方程較為理想。此外,還對氯氧鎂水泥基粉煤灰發泡混凝土的耐水性進行了相關實驗,發現磷酸有較好的耐水性效果,同時找到了其合適的摻量范圍。
  3. The results showed that the gradation, which designed by volumetric methods, has perfect water - stability and other pavement performance also can meet the demands of expressway. by integrating compaction capacity and pavement performances, the optimal ratio of the structural layer thickness to the maximum particle - size is 2. 5. the water resistance of the mixture added amine type anti - stripping agent attenuates severely after long - term aging, but the mixture added hydrated lime not only can improve obviously the capacity of water resistance, but also has perfect long - term pavement performance

    研究結果表明,採用體積法設計的級配不僅具有較好的水穩定性而且其它路用性能均滿足高速公路面層的要求;綜合考慮壓實性能及路用性能,提出了瀝青路面表面層結構層厚度與混合料最大粒徑的合理比例為2 . 5 ;摻有液體胺類抗剝落劑的瀝青混合料經長期老化后其抗水損害能力衰減嚴重,而摻加消石灰的混合料能顯著提高其抗水損害能力,且長期性能較好,是一種優良的抗剝落劑。
  4. On systematic analysis of engineering property of the aeolian sand, we choose cement stabilized aeolian sand, cement stabilized mixture of aeolian sand and soil, lime - fly ash stabilized aeolian sand, lime stabilized mixture of aeolian sand and soil and lime - cement stabilized mixture of aeolian sand and soil as object of research. on the base of the determination and analysis of temperature contraction property, aridity resistance property and strength of the stabilized aeolian sand mixture, this paper mainly analyses influential factors and inherent law of property about the stabilized aeolian sand mixture, and provides scientific foundation for the using of aeolian sand as paving material

    本文在系統分析風積沙工程特性的前提下,以水泥穩定風積沙、水泥穩定混合沙土、石灰穩定混合沙土、石灰粉煤灰穩定風積沙和水泥石灰穩定混合沙土作為底基層材料研究對象,在對其溫縮、干縮以及強度和模量等性能指標的測試、分析的基礎上,研究分析了這些穩定風積沙混合料各性能的影響因素和內在規律,為風積沙用作沙漠地區公路路面材料提供了科學依據。
