衬层

12 All temporary drainage channels shall be lined with concrete to prevent erosion.

3.12 所有临时排水道均须以混凝土筑砌衬层，以防侵蚀。

Four kinds of stainless steel lined composite pipes were produced using C—T process with raw materials Fe〓O〓, CrO〓, NiO, chrome iron and Al powders.

本论文主要研究在采用离心——铝热法制备不锈钢内衬复合钢管过程中，原料的配方以及工艺参数对不锈钢内衬层的成分、组织、裂纹和性能的影响。

Em brane and the underlying compacted clay must be guaranteed in the structural design of the compo site liner.

在复合衬层设计中应保证土工膜与其下的压实粘土层的紧密良好接触，并避免土工膜单独作为衬层使用。

The indexes of refraction of the material of the fibers in the scrim and of the adhesive are similar so that when the layer of adhesive is pressed against a substrate through the backing layer, the adhesive will more totally wet the fibers of the reinforcing scrim, causing them to become significantly less visible in the reinforced tape adhered to the substrate.

稀松无纺织物纤维材料和粘合剂的折射率是相似的，当粘合剂层通过背衬层被按压在基片上时，粘合剂会更完全地润湿增强的稀松无纺织物纤维，使其在粘贴于基片上的增强胶带中变得明显更不可见。

The present invention provides a reinforced tape including a visually transparent backing layer, a reinforcing scrim preferably of fibers made of visually transparent material along one surface of the backing, and a layer of transparent adhesive covering but not totally wetting the reinforcing scrim so that the scrim is visible along the backing layer before the tape is applied to give a user a visual indication of the strength of the tape.

本发明提供了一种增强胶带，包括一个视觉透明背衬层，位于该背衬一个表面上的一种优选由视觉透明材料制成的增强稀松无纺织物，和一个视觉透明粘合剂层，覆盖但不完全润湿该增强的稀松无纺织物，因此在应用该胶带之前，该稀松无纺织物在背衬层上是可见的，给使用者提供了胶带长度的可视指示。

The liner is a polymeric elastomer coating between propellant and insulation layer or case.The liner-forming is a special step in production of solid rocket motor.

衬层是推进剂与绝热层或壳体之间的高分子弹性体涂层，衬层成型是固体火箭发动机生产中的一种特种工序。

Through this material one could setup an overall impression of the study content and the study method.In order to investigate the basic heat transfer characteristics of regeneratively cooled scramjet, in the second chapter, one dimensional heat transfer model of regeneratively cooled scramjet was developed. In this model, N-R correlations were used to describe hot gas-side and coolant-side convection heat transfer. Simple model of gas properties was also used.

为了初步了解超燃冲压发动机再生冷却传热的基本特征，第二章建立了超燃冲压发动机再生冷却的一维传热数理模型，采用了准则关系式描述燃气侧和冷却剂侧的对流换热，采用了简化的燃气物性模型，并对衬层材料、衬层厚度和冷却剂流量进行了参数研究。

And 0. 1% of those from a geom. em brane liner with sub soils of medium permeability. For a composite liner with poor contact between the geom.

在填埋场典型设计条件下，复合衬层年渗滤液泄漏量和溶质稳态泄漏量仅为粘土衬层的0.4%和1.2%，为土工膜衬层的0.9%和0.1%。

Therefore, the composite liner should be significantly better than the geom. embrane liner and the CCL as an engineered hydraulic barrier. However, close contact between the geom.

因此， 复合衬层在防止渗滤液和污染物泄漏方面较土工膜衬层和压实粘土衬层具有明显优势，可作为卫生填埋场防渗衬层的优先推荐结构。
