例句与用法

  • The scientists implanted the " ice recrystallisation inhibition gene " into a host plant in australia and replicated the anti - freeze properties
    科学家们将这“抑制冰再结晶基因”导入澳大利亚的一种本土植物体内,于是这种植物也具备了防冻特性。
  • This paper unfolds engineering disposition and theoretical research of negative temperature high performance concrete ( nthpc ) with the damage of many factors motivation , the project background based on qing - zang railway engineering , which is one of four - emphasized engineering during the tenth five - plan . due to the difference of environment of construction and service between nthpc and ordinary concrete , and therefore durability of nthpc is required to higher level . at a first , nthpc must avoid frozen damage at early age and possess anti - freezing property at later period , in order to meet engineering practicable application need , and this are two emphasized and difficult problems , as for nthpc ; by means of mechanism analysis about deicing - agent ingredient and anti - freezing at early period , adopting composite technique routine of mineral addition + anti - freezing element + water - reducer4 - air - entraining + anti - erosion of steel component etc , based on orthogonal experimental approach , fd - 1 composite functional admixtu re was manufactured , which has more property and orientation on qing - zang railway
    负温混凝土由于和普通混凝土在施工环境及服役环境上存在的差异,因此表现为比普通混凝土更为较高的耐久性要求;负温混凝土首先要避免早期的冻害以及具备长期抗冻性能,才能够满足工程实际应用的要求,这也是负温混凝土必须解决的两大技术关键;通过对目前常用防冻剂组分作用机理的分析研究及混凝土早期防冻机理探讨,采用矿物外加剂+防冻组分+高效减水剂+引气+阻锈组分功能复合的技术路线,通过正交试验设计复配了适应青藏铁路工程要求的专用多功能复合型外加剂fd - 1 ;并在此基础上配制不同等级负温高性能混凝土,开展一系列包括硫酸盐侵蚀、氯离子渗透、抗冻融循环、收缩及耐磨性等耐久性能研究;通过对fd - 1组分和掺量的调整,优化负温混凝土在施工特性、力学指标和耐久性三个方面的兼容、协调性。
