本研究以污染严重的太湖五里湖为研究对象，对室内长效模拟和疏浚区/非疏浚区比较，进行了两种不同模拟疏浚深度的底泥培养实验，同时对疏浚后环五里湖河道进行了磷出入湖量和湖面磷含量同步调查分析，分析底泥疏浚前后水体磷含量变化，结合逐月出入湖量的初步分析，研究疏浚对湖水中磷含量的影响。

In the paper the author relates systematically the research fruits in the program of Research on Sand Slurry Abrasion Mechanisms of Dredging Conditions and New Wear-Resistant Materials. The main contents and innovations are listed as follows.Summarized and analyzed are the wear researches and developments, and the methods of increasing materials wear-resistance. From the viewpoint of the characteristics of two-phase liquid sand slurry wear, combined with the examination and study on easily damaged workpieces, the wear failures basic rules are pointed out, of the pump shell and the cutter-piece on service, and the general principles of material wear-resistant designs put forward. The sand slurry abrasion tester has been designed and developed which can simulate general dredging conditions. Summarized and presented are the position-exchange measuring method of sand slurry abrasion test and the experiment specification of sand slurry wear test of dredging conditions.

The orchard, the meadow, the deep tangled wildwood, And every loved spot which my infancy knew; The wide-spreading pond, and the mill that stood by it: The bridge and the rock where the cataract fell; The cot of my father, the dairy-house nigh it, And e 'en the rude bucket which hung in the well:The old oaken bucket, the iron-bound bucket, The moss-covered bucket which hung in the well.

果园、牧场、幽深的原始森林，以及幼年时所知道的每一个心爱的地方；开阔的池塘，还有池塘旁边的磨坊，大瀑布下面的桥梁和岩石，父亲的帆布床，还有附近的牛奶厂，甚至悬挂在井口的简陋的水桶：旧橡木桶，包着铁皮的桶，悬挂在水井上方的长着苔藓的桶。

Try in make clear, hydraulic pressure shovels dredger, grab bucket to shovel dredger construction efficiency instead instead taller, dredge of dredger of grab bucket type shovels type dredger to affect degree small; to wring dredger suction type to water environment than turning over, contain a lot ofas a result of bottom mud sundry, suction inlet jams extremely easily, apply to; of dredge of mud of Suzhou river bottom to undertake to groovy grab bucket environmental protection is transformed hard, the influence of earth of hourglass of leakage of the grab bucket in reducing dredge process significantly to water system water quality, be worth promotion application.

中试表明，液压反铲挖泥船、抓斗反铲挖泥船施工效率较高，抓斗式挖泥船疏浚比反铲式挖泥船对水环境影响程度小；绞吸式挖泥船，由于底泥富含杂物，吸口极易堵塞，难以适用于苏州河底泥疏浚；对常规抓斗进行环保改造，显著减少疏浚过程中抓斗漏水漏土对水体水质的影响，值得推广应用。

Not a full blushing goblet could tempt me to leave it, Though filled with the nectar which Jupiter sips; And now, far removed from thy loved habitation, The tear of regret will intrusively swell, As fancy reverts to my father 's plantation, And sighs for the bucket which hangs in the well: The old oaken bucket, the iron- bound bucket, The moss-covered bucket, which hangs in the well.

甚至一只装满红酒的高脚杯都不能使我离去，尽管高脚杯中装着朱庇特常喝的甘露。现在远远地离开了你们心爱的地方，悔恨的眼泪不住地越流越多。当记忆回到父亲的大农场时，我便为悬挂在水井上方的桶叹息起来，那些悬挂在水井上方的，旧橡木桶，包着铁皮的桶，长着苔藓的桶。
