采用凝胶电泳法和气相色谱法比较骆驼乳、牛乳和山羊乳在蛋白质和脂肪酸两方面的差异。电泳结果显示:不同产地骆驼乳粉乳蛋白成分比例存在差异,生产工艺对其乳蛋白和乳脂球膜蛋白的组成比例均有显著影响;骆驼乳、牛乳和山羊乳蛋白成分存在显著差异,其中骆驼乳不含β-乳球蛋白和αs1-酪蛋白,而牛乳和山羊乳中不含免疫球蛋白G2(immunoglobulin G2,IgG2)和IgG3,因此凝胶电泳法可用于骆驼乳中掺牛乳、山羊乳的鉴别分析。气相色谱检测结果显示:骆驼乳和羊乳中均检出31种脂肪酸,牛乳检出29种脂肪酸;骆驼乳中短链脂肪酸较牛乳和山羊乳少,而大部分长链脂肪酸含量显著高于牛乳和山羊乳。脂肪酸主成分分析结果显示,不同物种乳类脂肪酸差异明显,并且掺假骆驼乳与骆驼乳可明显区分,可用于掺加牛乳、山羊乳的骆驼乳中脂肪酸的鉴别分析。

选取2010-2019年攀枝花地区气象数据,采用基于“黄金分割率”的人体舒适度指数计算和等级划分法,分析攀枝花地区气候康养资源,并与南北方典型城市对比探析其优势;分析2015-2019年攀枝花地区呼吸系统疾病就诊人数特征及其受当地同期气候、舒适度的影响,同时与北方典型城市进行对比。结果表明:攀枝花地区日平均气温14.6℃~26.8℃、日平均气压876.2~885.3 hPa、相对湿度59%~74%、冬季月均日照时数217.5~247.2 h。气候上属于无冬区,具有避寒康养优势;夏季最热月在5月,而盛夏时(7-8月)比中国东部地区气候宜人,具有避暑康养优势。舒适度研究显示,当地“舒适”、“凉爽”等级天数最多,无“严寒”、“寒冷”和“冷”等级天气,多年平均年广义舒适期可达246.4天,宜居利养。当地呼吸系统疾病发病呈现低温效应,“舒适”、“微热”等级天气康养效果最佳,21℃~23℃气温范围及6-9月雨季气候可有效降低发病风险。相对危险度(RR)研究显示,若北方候鸟人群冬季前往相对温暖的攀枝花避寒旅居,此气候趋利行为对应呼吸系统疾病发病人次占比降低,降幅在24.62%及以上,表明攀枝花“暖冬”气候对相关候鸟人群的发病风险降低效应,即避寒康养效应。

This paper proposes an automatic algorithm to determine the properties of stochastic processes and their parameters for inertial error. The proposed approach is based on a recently developed method called the generalized method of wavelet moments (GMWM), whose estimator was proven to be consistent and asymptotically normally distributed. This algorithm is suitable mainly (but not only) for the combination of several stochastic processes, where the model identification and parameter estimation are quite difficult for the traditional methods, such as the Allan variance and the power spectral density analysis. This algorithm further explores the complete stochastic error models and the candidate model ranking criterion to realize automatic model identification and determination. The best model is selected by making the trade-off between the model accuracy and the model complexity. The validation of this approach is verified by practical examples of model selection for MEMS-IMUs (micro-electro-mechanical system inertial measurement units) in varying dynamic conditions.
