回弹值 meaning in English
rebound value
Examples
- Influence of various rebound value on the compression strength of concrete tested by rebound method
不同回弹值对回弹法测定混凝土抗压强度的影响 - In the curve ( empirical formula ) , the concrete rebound value with wide randomness is a dependent variable , while the compressive strength value with narrow randomness is an independent variable , and a location parameter is added , so it is more suitable for engineering practice
将随机性较大的混凝土回弹值作为因变量，随机性较小的抗压强度值作为自变量，并且增加了一个位置参数，更加符合工程的实际情况。 - Relationship between concrete compression strength and rebound and ultrasonic speed value was studied by test . special regressive equation was obtained to predict concrete compression strength . also , empirical regressive equation was got to predict the temperature acting on concrete structure
试验研究了火灾高温后并考虑静置时间影响的混凝土抗压强度与回弹值、超声波速值之间的关系，得出了利用回弹法、超声法和超声回弹综合法评定火灾后混凝土抗压强度的专用测强公式；得出了利用超声法推定混凝土受火温度的经验回归公式。 - This formula used inverse regression and data fusion technical and maximum likelihood theory , then this method enabled random sample value obtained in ultrasonic and rebound method of different detection population to mix together effectively , and reach estimation of concrete strength
该公式利用逆回归理论、数据融合技术和最大似然原理，将回弹值和声速值分别看作被解释变量，将来自超声法和回弹法不同量纲的检测数据进行有效融合，得出混凝土强度的推定值，该推定结果具有无偏性和方差最小性质。 - Concrete compression strength was predicted by artificial neural network ( ann ) considered three factors , such as temperature , standing time and cooling and curing process after cool . also it was predicted in different rebound and ultrasonic values . fire resisting performance of concrete was studied and predicted
