大家好，我是小跳，我来为大家解答以上问题。小绿鲸英文文献翻译，英文文献翻译很多人还不知道，现在让我们一起来看看吧！

1、In the construction of hydraulic structures in regions with a rigorous climate the State Standard GOST 4795- 68 for hydraulic engineering concrete calls for the construction of protective coatings having simultaneously high heat-insulating and waterproofing properties in the variable water-level zones of the structures. Heat-insulating and waterproofing coatings on a base of such traditional materials as mastic asphalts and lightweight asphaltic concretes with protective enclosures of metal and wood are finding use in hydraulic construction practice in the USSR[1-4]. 根据国家标准GOST 4795- 68对水利工程混凝土的要求，在严酷气候的区域建设水利设施，必须在设施结构水位变化的区域建造一个隔绝高温及防水的保护层。

2、在苏联的水利建设通常所使用的隔热及防水层的传统基础材料是涂以沥青砂胶及轻型沥青混凝土的金属与木材防护罩[1-4]。

3、 However, the considerable weight (150-500 kg/mZ), labor requirements, and installation of numerous anchor bolts for securing the traditional insulating and waterproofing materials on the surfaces being protected stimulated the search for new types of protective coatings. 然而，鉴于其相当的重量(150-500 kg/mZ)和需要大量的劳动力，而且，为了稳固防护面的传统隔热及防水材料，还需要安装许多锚定螺杆，这些缺点激发了寻求新型保护层的研究。

4、 One such new type of insulating and waterproofing coating is foamed epoxy, developed in the research department of the All-Union Planning, Surveying and Research Institute (Gidroproekt). The principal material is foamed epoxy- a foamed plastic on a base of epoxy resins produced on the site by simple mixing of the basic components in given ratios and sequence [5-6]. Low-density foamed epoxies have high heat-insulating and waterproofing properties and good adhesion to concrete, as a consequence of which the insulating-waterproofing coatings on their base are of small weight (8- I0 kg/m 2) and require few anchor bolts for securing. 由勘测与科学研究学院，全盟策划（水利项目）研究部所开发的泡沫环氧树脂是其中的一种新型隔热与防水涂层。

5、主要材料就是泡沫环氧树脂；这是将基本成分按比例及顺序在现场简单混合而成的一种基于环氧树脂的泡沫塑料[5-6]。

6、低密度的泡沫环氧树脂拥有隔绝高温与防水性能以及与混凝土有很好的粘结度，因此以其为基础的隔热与防水层的重量很轻(8- I0 kg/m 2)，而且需要稳固的锚定螺杆数量也很少。

7、 The experience of using the foamed epoxy insulating-waterproofng coating on the Gorky hydroelectric station，Kislaya-Guba tidal power plant and the No. 2 hydrodevelopment on the Moscow Canal showed that its use is economically justified only in the case of constructing the structures by the buildup method, when the weight of the insulating-waterproofing material is decisively significant, or in the case of constructing hydrodevelopments in remote and hard to reach regions, where the transportation expenses are great [7]. Therefore, the need arose to perfect the foamed epoxy insulating-waterproofng material from an economic standpoint. 通过高尔基水电站、吉斯拉亚-库巴潮力发电厂及莫斯科运河的第2号水利开发站的使用经验显示，只有使用组合方式建设的水利设施结构，当隔热与防水材料的重量成为重要关键时，或者建于偏僻及难以到达地区，运输费用昂贵的水利开发站，采用这种泡沫环氧树脂的隔热与防水材料才能显示出它的经济性[7]。

8、因此，从经济的角度，改善这种材料成本的需要应运而生。
