天强度 meaning in Chinese
four-week age strength
Examples
- The enhancement effect and its sub - effect of superfine slag powder contribute most on slag cement ' s 28th strengths , in which the pozzolanic effect is the main factor and is amount to 80 %
矿渣微粉的增强效应及其子效应都对矿渣水泥28天强度贡献最大，并以火山灰效应为主，约占总效应的80 。 - Prediction of 28 day ' s compressive fly ash concrete strength , which is very significant to increasing the efficiency of concrete production , is a typical multi - variable , nonlinear system
粉煤灰混凝土28天强度预测和配合比优化设计在实际工程生产中具有十分重要的意义。粉煤灰混凝土强度预测是一个典型的多变量，非线性系统。 - Results demonstrated that a good quality hpc with adequate 28 - day compressive strength could be achieved by partially replaced cement with ground mineral additives and the use of superplasfics
试验结果表明通过用磨细的矿物掺和料部分取代水泥配合高效减水剂，完全可以配置出28天强度满足要求而其它方面的性能优良的高性能混凝土。 - In this paper , on the base of the comprehensive analysis of the development of rpc in domestics and abroad , in terms of the practical condition in fuzhou , and optimizing raw material and admixture , the rpc200 whose compression strength is 207mpa at 7d have been successfully developed
本文在综合分析国内外活性粉末混凝土（ rpc ）研究成果的基础上，结合国内及本省的实际情况，通过优选原材料和外加剂，成功地配制出7天强度达207mpa的rpc200 。 - ( 2 ) another interesting phenomenon is founded that the center of south asia high in the upper level of troposphere is stabile and nearly motionless during the processes of the westward extension of western pacific subtropical high , but its eastern ridge strengthens and extends eastward remarkably because of the anticyclone moves westward over the southeast japan , which may lead to the westward extension of subtropical high in the middle level of troposphere . ( 3 ) in the low level of troposphere , the north australia cold air activity plays an important role on the westward extension of subtropical high
( 2 )本文在研究副高西伸过程中指出，高层200hpa上日本东南部的高压并入南亚高压，导致南亚高压脊的增强发展，对低层500hpa上副高的加强、西伸可能起到引导的作用；同时，对流层低层850hpa上孟加拉湾槽在副高西伸过程中加深，并在西伸脊点到达最西点的前4天强度达到最强，这为预报西太平洋副高的活动提供了参考。
