例句與造句

1. 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
   因為最佳級配范圍是與粒料的粒徑大小有關(guān)的，所以在基層材料配合比設(shè)計時可首先將材料級配限制在最佳級配范圍以內(nèi)，然后通過系統(tǒng)的溫縮、干縮性能試驗以及抗壓強度校核試驗，最終確定抗裂性較好的合理水泥劑量。
2. We must take account of crack resistance when doing mixture design . after systematic and scientific determination and analysis of temperature contraction property , aridity contraction property and strength index , the thesis have chosen the best grade limits in which crack resistance and compressive strength are high . this conclusion is based upon standard ? grade limits of cement stabilizing crushed stones subbase
   本課題在對水泥穩(wěn)定類材料溫縮、干縮性能以及強度和模量等指標(biāo)的測試分析前提下，以規(guī)范原有的水泥穩(wěn)定碎石基層級配范圍為基礎(chǔ)，選擇出抗裂性和抗壓強度兩項指標(biāo)俱佳的級配范圍。
3. It's difficult to find grading limit in a sentence. 用grading limit造句挺難的
