2.数据预处理：（1）对采集的数据进行去噪处理，确保数据准确性。（2）将历史采集的数据（包含本次采集）进行聚合，形成数据集X，并针对数据集X中的冲击强度字段，计算出其平均值。
3.计算线性回归斜率a和截距b:基于数据集X（以高角度晶界占比为自变量、冲击强度为因变量），运用SLOPE函数，基于最小二乘法原理确定斜率a，运用INTERCEPT函数确定截距b。斜率a表示单位高角度晶界占比变化对环保柔性装配式侧石冲击强度的影响程度，截距b表示基准高角度晶界占比下环保柔性装配式侧石的冲击强度值。
4.结果运用：（1）计算比例系数k：k=|a/冲击强度平均值|×100%；（2）若k≥10%，则判定为“高影响”，若5%≤k＜10%，则判定为“中影响”，若k＜5%，则判定为“低影响”。

This dataset focuses on analyzing the effect of high-angle grain boundary (HAGB) fraction on the impact resistance of environmentally friendly flexible assembled curb stones, and reveals the quantitative relationship between grain boundary characteristics and material crack propagation resistance, plastic deformation capacity, as well as energy absorption efficiency. It provides critical decision-making basis for the company (as the manufacturer) and external stakeholders, exhibiting significant application value, which is reflected in the following two aspects:
1. Optimizing microstructure regulation processes: The company can precisely control heat treatment process parameters by analyzing the impact of different HAGB fractions on the impact resistance of curb stones, construct an optimal grain boundary characteristic distribution, and significantly improve the material's crack deflection ability and dynamic impact resistance.
2. Promoting the application of grain boundary engineering in the building materials field: This dataset can provide support for research institutions in the field of microstructure design, assisting them in investigating the regulatory mechanism of high-angle grain boundaries on the multi-scale mechanical behavior of materials, and providing theoretical guidance for the development of a new generation of high-toughness environmentally friendly building materials.
The specific implementation steps of the dataset are as follows:
1. Data collection: Real-time recording of impact resistance test data of environmentally friendly flexible assembled curb stones under different high-angle grain boundary fractions, including fields such as test sample number, test time, high-angle grain boundary fraction/%, and impact strength/J/m².
2. Data preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate all historically collected data, including this batch, to form dataset X, and calculate the average value of the impact strength field in dataset X.
3. Calculation of linear regression slope a and intercept b: Based on dataset X (with high-angle grain boundary fraction as the independent variable and impact strength as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b. Slope a represents the degree of influence of unit high-angle grain boundary fraction change on the impact strength of environmentally friendly flexible assembled curb stones, while intercept b represents the impact strength value of environmentally friendly flexible assembled curb stones under the reference high-angle grain boundary fraction.
4. Result application: (1) Calculate the proportional coefficient k: k = |a / average impact strength| × 100%; (2) If k ≥ 10%, it is judged as "high impact"; if 5% ≤ k < 10%, it is judged as "medium impact"; if k < 5%, it is judged as "low impact".
