Because the best grade limits does not vary with material property , firstly , we can confine material grade to the best grade limits when doing subbase mixture design , secondly , after systematic temperature contraction test , aridity contraction test and compressive strength correction test , we can determine the best cement percentage which has the best crack resistance property 因为最佳级配范围是与粒料的粒径大小有关的，所以在基层材料配合比设计时可首先将材料级配限制在最佳级配范围以内，然后通过系统的温缩、干缩性能试验以及抗压强度校核试验，最终确定抗裂性较好的合理水泥剂量。

Abstract : a new proven design of a complete mechanic , electric and computerized automation system is introduced , which is mainly used in the workshop polythene film blowing . the function of the system is to automatically compound the pe granular materials according to the different requirements of tens of film extrusion and blowing machines , and then convey the compounded materials to the specific machines in one or several workshops within an area of some hundred meters 文摘:介绍了最新研制成功的一种全自动成套机械、电气、计算机一体化系统，该系统主要应用于生产聚乙烯薄膜的吹膜车间，其功能是给分布在几百米范围内的1个或多个吹膜车间内的几十台乃至上百台挤塑吹膜机按各自的配方自动配制生产原料( pe粒料) ，并将配制的原料自动输送给需要的挤塑吹膜机。
The factory has established the quality control system according to the iso9000 standard , has yearly produces the disposable use infusion 50 , 000 , 000 set of , disposable use asepsis injector 100 , 000 , 000 with the medical level pvc aggregate 600 ton scales of production , is the national big disposable medical service thing production enterprise 工厂按iso9000标准建立了质量管理体系，具有年产一次性使用输液器5000万套、一次性使用无菌注射器1亿支和医用级pvc粒料600吨的生产规模，是全国较大的一次性医疗用品生产企业。
Designning well tube and drill - hole diameter in order to increase thickness of both annular packing gravel and water - resisting clay , nylon net packing around well tube filters , designing filter layer on the boundary between packing gravel and water - resisting clay and ramming the gravel by working the piston into the well after gravel packing completion and the filling clay for salt - water resisting etc . we succeeded in constructing 3 drinking - water wells in minqin county , proved the affectivity and feasibility of using it and giving a certain technical demonstration of construction of drinking - water well in the same similar to this area 通过孔径与管径的调配设计，增大环状粒料层和止水粘土层的厚度；滤水管外包尼龙纱网；粒料与止水粘土接触界面上设计反滤层；填粒后先行拉活塞利用水力夯实粒料层，再投粘土球止掉上部咸水等措施，在民勤县三口人饮水井施工中取得显著效果，证明了该套成井工艺的有效性和可行性，有望为同类地区人饮水井施工提供技术示范作用。
The old asphalt mixture being dealt with cement is a cold in - place recycling method . the mechanism is that the crushed asphalt mixture and lime soil are reused and is stabilized by cement additive . so the material can be applied in base and subbase course such as cement stabilized aggregate 利用水泥处治废旧沥青路面材料属于沥青路面冷再生的范畴，其再生机理是将加工破碎的废料(包括废旧的沥青混合料和部分灰土基层)重新利用，经过水泥进一步的稳定作用，形成与水泥稳定级配粒料类似的基层和底基层材料。
