黄曲条跳甲是蔬菜重要害虫，生产实践中亟需高效安全的防治药剂。采用浸渍法从有机磷、拟除虫菊酯、新型杂环、植物源类等共16种常用杀虫剂中筛选出对黄曲条跳甲成虫触杀活性较高的鱼藤酮和氟虫腈，两者以3：2混用时，处理后24h对黄曲条跳甲成虫的LC50为9．60μg／mL，共毒系数为230．14，增效作用明显。以此配方配制成6％鱼氟乳油，质量稳定合格，触杀活性强，作用迅速，以0．45μg/cm^2和0．75μg/cm^2剂量药膜法处理后48h校正死亡率分别为83．72％和98．70％；以50μg/mL处理试虫致死中时LT50为10．12min。鱼氟乳油处理显著增强对黄曲条跳甲成虫呼吸的抑制作用可能是其主要增效机制。6％鱼氟乳油450mL／hm^2处理后10天内，田间虫口减退率为72％～96％．防治效果为90％以上。

湖南省水土流失面积达40393km2,占全省总面积的19.07%,是水土流失较严重的地区。从地理、气象、人为等因素对湖南省的水土流失进行了分析。结果表明,南高北低的地理特征,降雨量山地大于平原的气候条件,植被破坏的人为因素是造成水土流失的主要原因。据此,提出了从山地到平原,从支流到干流,从生态集雨到灌排结合的治理模式,从而达到防止水土流失和改善生态环境的目的。

通过对河南汝阳东沟特大型钼矿床矿石物质组成及选矿新工艺的论证评价,揭示了该矿床物质成分的复杂性及选矿性能,得出以下认识:1)赋矿岩石以碳酸盐与铝硅酸盐为主要组分,受后期构造热液影响,矿石破裂变形、扭曲以及交代现象十分普遍,因而矿石具多种复杂结构,这些因素可对矿石的选矿性产生严重影响;2)对选矿方案给予多方面论证,找出了矿石技术加工的难点及影响因素,并在选别过程中给予了充分考虑;3)可浮性试验,找出脉石矿物上浮所需时间及与目的矿物之间的关系;4)粗选试验,从七个方面对目的矿物的捕收剂及其用量和添加地点、磨段细度、脱泥考察、石英和硅酸钠用量等都进行了全面试验,并找出各方面适应矿石物质组成和选矿性能的楔合点,给出了一系列参数作为依据;5)钼精选试验,分别进行了再磨细度、抑制剂种类、全开路和浮选闭路流程等四方面试验,使最终产品的选别指标满足国家标准。结论:浮选使用70%-200目,再磨设置在83.5%-400目条件下,选用磷诺克斯与巯基乙酸钠配合,有效地抑制了黄铜矿、方铅矿等硫化物杂质的混入,再次精选获得钼精矿品位51.08%,钼回收率84.24%,达GB3200—82特级品标准。

针对地铁隧道人工冻结法施工过程中土层冻胀融沉变形控制难题,以上海地区典型重塑饱和粉质黏土为研究对象,开展了有无补水(无荷载)、不同荷载(补水)以及不同融沉方式下土体的冻胀融沉试验。试验结果表明:(1)在相同的冷端温度和温度梯度下,补水条件致使冻结锋面稳定时所需的时间比不补水条件长;(2)随着竖向荷载的增加,冻结锋面高度与冻结时间、冻结锋面平均移动速率之间的关系均为一阶衰减指数函数;(3)随着竖向荷载的增加,土体的冻胀变形、补水量和最终融沉量均减小,说明荷载抑制土体冻胀的同时也抑制土体融沉;(4)相同荷载条件下,土体经冻融后,在卸载融沉方式下发生膨胀,而在加载融沉方式下发生沉降,且沉降量随着荷载的增加而增大。
