为实现脱臭馏出物绿色、清洁、高效甲酯化，达到环保生产的目的，通过单因素实验和响应面实验对生物酶法催化脱臭馏出物甲酯化反应的工艺条件进行了优化，测定了反应前后维生素 E含量的变化，并将新工艺应用于实际生产线。结果表明：生物酶法催化脱臭馏出物甲酯化的最佳反应条件为加水量1%(以脱臭馏出物质量计)、甲醇用量11.5%(以脱臭馏出物质量计)、固定化脂肪酶用量0.3%(以脱臭馏出物质量计)、反应温度35.6 ℃，在最佳条件下反应8 h脱臭馏出物中游离脂肪酸酯化率达到92.59%，甘油酯酯化率达到94.95%；生物酶法催化脱臭馏出物甲酯化反应过程中维生素 E损失少，收率达到93%；与浓硫酸催化甲酯化工艺相比，产品维生素E(50%维生素E)总收率提高了3.47百分点，植物甾醇总收率提高了3.26百分点。综上，生物酶法催化脱臭馏出物甲酯化，可以得到较高的酯化率，提高了产品维生素 E和植物甾醇收率。 In order to realize the green, clean and efficient methyl esterification of deodorized distillates and achieve the goal of environmental protection, the reaction conditions of the bioenzyme-catalyzed methyl esterification of deodorized distillates were optimized by single-factor experiment and response surface methodology, and the changes of vitamin E content before and after the reaction were measured. In addition, the new process was applied to the actual production line. The results showed that the optimal reaction conditions for the methyl esterification of deodorized distillates catalyzed by bioenzyme were as follows: water dosage 1%(based on the mass of deodorized distillates), methanol dosage 11.5% (based on the mass of deodorized distillates), immobilized lipase dosage 0.3% (based on the mass of deodorized distillates), reaction temperature 35.6 ℃. Reaction under the optimal conditions for 8 h, the esterification rate of free fatty acid and glycerol ester in the deodorized distillates reached 92.59% and 94.95%, respectively. In the methyl esterification of the bioenzyme-catalyzed deodorized distillates, the loss of vitamin E was low, and its yield reachedg 93%. The total yield of vitamin E (50% vitamin E) increased by 3.47 percentage points and the total yield of phytosterols increased by 3.26 percentage points compared with the concentrated sulfuric acid catalyzed methyl esterification process. In conclusion, the bioenzyme-catalyzed methyl esterification of deodorized distillates posses higher esterification rates and yields of vitamin E and phytosterols.

In natural traffic scene, the bounding box sizes of different road targets vary greatly. The existing real-time object detection algorithm YOLOv3 can not balance the detection accuracy of large and small targets and has poor performance in the task. To solve the problems, the feature fusion module of YOLOv3 target detection algorithm was redesigned to realize the multi-scale feature stitching. The detection module was improved by adding two extra feature output modules for small targets, and a new multi-scale detection method of YOLOv3_5d for road targets was obtained with 5 detection scales. The experimental results show that the average precision of the improved YOLOv3 _5d algorithm is 0. 580 9 on BDDlOOK dataset, which is 0. 082 0 higher than that of original YOLOv3. The running speed is 45. 4 frames · s -1, which can meet the real-time requirement. [ABSTRACT FROM AUTHOR]

Objective: To study the clinical effect of Xiaochaihu particles plus nebulization by ambroxol hydrochloride on the acute exacerbation of chronic bronchitis and its influence on the inflammatory cytokines. Methods: 160 paticnts with acute exacerbation of chronic bronchitis who received therapy from January 2016 to July 2016 in our hospital were selected as research objects and divided into the observation group and control group according to the method of treatment, the control group was given hydrochloric acid ammonia bromine atomization inhalation treatment, the observation group was treated on the basis of control group combined with the small bupleurum granule, the clinical efficiency and clinical symptoms disappearence time, pulmonary function and inflammatory factors levels of two groups of patients before and after treatment were compared. Results: After treatment, the total effective rate of observation group was as high as 96. 3％, which was significantly higher than that of the control group (85.0％, P＜0.05). After treatment, the serum IL-6, IL-8, TFN-α levels of observation group were obviously lower than those of the control group (P＜0.05), the pulmonary function, clinical symptoms disappearence time were significantly better than those of the control group (P＜0.05). Conclusion: Small radix bupleuri particles plus nebulization by ambroxol hydrochloride could significantly shorten the clinical symptoms disappearence time, improve the lung function and clinical curative effect of acute exacerbation of chronic bronchitis, which might be related to the inhibition of inflammatory response.
