低共熔溶剂协同超声波提取红枣中总黄酮的研究

以红枣作为原料,采用低共熔溶剂协同超声波提取红枣中的总黄酮.试验首先遴选氯化胆碱/乙二醇体系作为低共熔溶剂,然后在单因素试验的基础上进行正交试验,得到红枣总黄酮的最佳提取工艺条件.结果表明:在红枣粉过60目筛、60℃C的提取条件下,低共熔溶剂协同超声波提取红枣中总黄酮的最佳工艺条件为低共熔溶剂稀释10倍、料液比1:22...     

Research on image segmentation of Miao costume patterns based on the RSKP-UNet model北大核心CSCD

The Miao nationality is the sixth largest ethnic group in China which has a history of thousands of years. It has created a unique material culture and spiritual culture in its development process and the Miao costume is a highly condensed collection of the material and spiritual culture of the Miao nationality. As one of the unique symbols of Miao culture the Miao costume has profound cultural heritage and cultural connotations. The patterns of the Miao costume are particularly eye-catching as they not only symbolize the wisdom of the Miao people in thousands of years of production and life but also symbolize the pursuit of the good spirit of the Miao people. However under the impact of modern pop culture and foreign culture these cultural symbols are gradually disappearing. In order to protect and inherit them the Miao costume pattern segmentation has become the most important work. However the Miao costume pattern segmentation is quite difficult. At present there are few studies on the extraction classification identification and preservation of the features of Miao costume pattern segmentation. With the excellent segmentation performance of the U-Net model and the advantages of easy deployment the paper improves the basic structure of the U-Net model and proposes a Miao costume pattern segmentation algorithm based on the RSKP-UNet Residual Selective-Kernel Parallel U-Net model. The algorithm adds Residual modules in the encoder part of the U-Net model to improve the feature extraction capability of the model and embeds the SKNet modules and ParNet modules in the decoder part to enhance the feature expression capability of the model. The paper uses evaluation metrics to measure the segmentation performance of the model and compares it with four segmentation models based on deep learning. The paper not only combines the current research focus-deep learning and attention mechanism but also introduces the Lovász-hinge loss function to effectively solve the problem of class imbalance in the Miao costume patterns. The RSKP-UNet model is better than other models in various segmentation indicators. Compared with the benchmark model U-Net the Dice coefficient IoU precision recall and accuracy are improved by 6. 98% 11. 07% 2. 89% 6. 75% and 3. 92% . The segmentation algorithm proposed in this paper realizes the extraction of the element content of the Miao costume patterns through image segmentation of Miao costume patterns which can be used to build the Miao costume pattern database in this way thus helping designers relevant researchers and organizations to provide research foundation and completing the protection and inheritance of the Miao costume culture. The paper also provides some reference for the segmentation research of other minority costume patterns. © 2022 Authors. All rights reserved.

松辽盆地北部深层断陷类型及风险勘探领域优选

松辽盆地北部深层断陷构造复杂,制约了断陷优选评价工作.依据沙河子组残留特征与演化规律,将深层断陷划分为“持续沉降型、改造叠合型、继承反转型、改造叠合反转型”4种类型.研究表明:复杂改造叠合型盆地经早期改造并残留下来,往往成为断陷主体或沉积中心,其烃源岩条件较好,同时早期构造活动产生了大量气源断裂,并使地层上倾或者削截方向直接与储集体接触,有利于天然气聚集;持续沉降型断陷盆地沉积环境稳定,有利于暗色泥岩发育,具有较好的源岩条件,后期改造作用弱,有利于天然气保存;将深层断陷划分为Ⅰ,Ⅱ,Ⅲ类勘探区,明确了近期风险勘探的有利区带.
