香精浓度对香氛留香时间的影响分析数据

本数据聚焦于分析不同香精浓度对香氛产品留香时间的影响，揭示了香精浓度与香气持久性、挥发曲线之间的量化关系，为公司(作为经销商)及外部相关方提供了关键决策依据，具有重要的应用价值。具体体现在以下方面:
1.优化香氛产品采购策略:公司可通过建立香精浓度-留香时间关联模型，优先采购香精浓度科学配比的香氛产品，确保所售商品在留香持久性方面满足消费者需求，
2.推动行业技术创新:本数据可为制造商提供香精浓度优化依据，推动其开发新型香精缓释技术实现香气的持久释放。1.数据采集：实时记录不同香精浓度下的香氛留香时间测试数据，包括测试样品编号、测试时间、香精浓度/%、香氛留香时间/h等字段。
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中的香氛留香时间字段，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（以香精浓度为自变量、香氛留香时间为因变量），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表示单位香精浓度变化对香氛留香时间的影响程度，截距b表示基准香精浓度下香氛的留香时间值。
4.结果运用：（1）计算比例系数k：k=|a/香氛留香时间平均值|×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 impact of different fragrance concentrations on the longevity time of scented products, revealing the quantitative relationship between fragrance concentration, aroma persistence and volatilization curve. It provides key decision-making basis for the company (as a distributor) and external stakeholders, and has important application value, which is specifically reflected in the following aspects:
1. Optimizing the procurement strategy for scented products: The company can establish a correlation model between fragrance concentration and longevity time of scented products, giving priority to purchasing scented products with scientifically formulated fragrance concentrations, so as to ensure that the sold products meet consumer demand in terms of aroma persistence.
2. Promoting industry technological innovation: This dataset can provide optimization basis for fragrance concentration for manufacturers, promoting them to develop new fragrance sustained-release technologies to achieve sustained release of aroma.

1. Data Collection: Real-time recording of test data on the longevity time of scented products under different fragrance concentrations, including fields such as test sample number, test time, fragrance concentration (%), and longevity time of scented products (h).
2. Data Preprocessing: (1) Denoising the collected data to ensure data accuracy. (2) Aggregating the historically collected data (including this collection) to form dataset X, and calculating the average value of the longevity time field of scented products in dataset X.
3. Calculation of linear regression slope a and intercept b: Based on dataset X (with fragrance concentration as the independent variable and longevity time of scented products as the dependent variable), use the SLOPE function to determine slope a based on the principle of least squares, and use the INTERCEPT function to determine intercept b. Slope a represents the degree of impact of unit fragrance concentration change on the longevity time of scented products, while intercept b represents the longevity time value of scented products under the reference fragrance concentration.
4. Result Application: (1) Calculate the proportion coefficient k: k = |a / average longevity time of scented products| × 100%; (2) If k ≥ 10%, it is classified as "high impact"; if 5% ≤ k < 10%, it is classified as "medium impact"; if k < 5%, it is classified as "low impact".
