为提高燕麦蛋白（OP）的功能性质，提高其品质,分别采用葡萄糖(G)、乳糖(L)、壳寡糖(C)、海藻酸钠(S)对燕麦蛋白进行湿法糖基化改性，探究4种不同分子大小的糖对燕麦蛋白糖基化产物（G-OP、L-OP、C-OP、S-OP）功能性质及结构的影响。结果表明：4种糖基化燕麦蛋白的溶解性较改性前均有较大提高，其中L-OP的溶解度（pH 7）较改性前提高了64.23百分点；4种糖基化燕麦蛋白的乳化活性指数（EAI）和乳化稳定性指数(ESI)均显著提高（p＜ 0.05），其中C-OP的EAI和ESI较改性前分别增加了8.91 m2/g和21.26百分点；4种糖基化燕麦蛋白的持水性、吸油性、体外消化性及表面疏水性较改性前均显著提高（p＜ 0.05）；SDS-PAGE、傅里叶红外光谱、荧光光谱分析表明，糖链的引入使OP空间结构发生了变化，证明了OP分别与4种糖发生共价结合生成糖蛋白。综上，虽然蛋白的糖基化反应是一种化学改性，但由于没有任何化学试剂参与，通过自发反应发生共价交联，生成具有良好功能性质的蛋白糖基化共价复合物，属于“绿色加工工艺”，适合高品质改性植物蛋白的研制。 In order to improve the functional properties of oat protein (OP) and improve its quality, OP was modified by wet glycosylation with glucose(G), lactose(L), chitosan(C) and sodium alginate(S) respectively to explore the effects of four sugars of different molecular masses on the functional properties and structure of oat protein glycosylation products (G-OP，L-OP，C-OP，S-OP).The results showed that the solubility of the four glycosylated oat proteins was greatly improved, and the solubility (pH 7) of L-OP increased by 64.23 percentage points compared with that without modification.The emulsifying activity index(EAI) and emulsifying stability index(ESI) of the four glycosylated oat proteins were significantly improved (p＜ 0.05), in which the EAI and ESI of C-OP increased by 8.91 m2/g and 21.26 percentage points respectively compared with those before modification.The water holding capacity, oil absorption, in vitro digestibility and surface hydrophobicity of the four glycosylated oat proteins were significantly improved (p＜ 0.05) compared with OP. SDS-PAGE, Fourier infrared spectroscopy and fluorescence spectrum analysis showed that the introduction of sugar chains changed the spatial structure of OP, further proving that OP covalently bound four sugars and formed glycoproteins.In summary, although the glycosylation reaction of protein is a kind of chemical modification, covalent cross-linking occurs through spontaneous reaction without the participation of any chemical reagent to produce covalent protein glycosylation complexes with good functional properties, which belongs to the "green processing technology", and is suitable for the development of high-quality modified plant proteins.

In order to establish ferrite phase transformation kinetics mathematical model of DP600 hot rolled dual-phase steel under the ESP process condition, the isothermal phase transformation and continuous cooling phase transformation experiments were conducted on the experimental steel by using the dynamic phase transformation dilatometer. Based on the measured ferrite phase transformation incubation time and ferrite volume fraction, the incubation time of ferrite phase transformation was calculated by combining classical nucleation theory above the deformation temperature, and the incubation time of ferrite phase transformation below the deformation temperature was calculated by fitting ∆GV according to the experimental data. Considering the influence of cooling rate, the additivity rule was modified and based on this, the starting temperature and volume fraction of ferrite phase transformation under continuous cooling conditions were calculated. The results showed that the calculated starting temperature and volume fraction of ferrite phase transformation using the modified phase transformation model are in good agreement with the measured values, which can be used to predict the ferrite phase transformation behavior of DP600 dual-phase steel under the ESP process.

Objective Fracture systems in shale reservoirs have an important impact on CH4 production and CO2 sequestration, and different geological characteristics of reservoirs have their corresponding optimal fracturing schemes. The study aims to investigate the effect of artificial fracture parameters on CO2 sequestration and CH4 production of Yanchang formation shale reservoirs in Ordos Basin. Methods Based on the geological conditions of shale reservoirs of Yanchang formation in Ordos Basin, a dual-porosity, dual- permeability homogeneous model was established to analyze the effects of artificial fracture half-lengths, fracture width, fracture height, fracture spacing, and the number of fractures on CO2 sequestration and CH4 production in CO2-ESGR. Results The results showed that fracture half-length fracture width and fracture height were positively correlated with CO2 sequestration and CH4 production, among which fracture width had the greatest influence. When the fracture width increased from 5 mm to 25 mm. CO2 sequestration increased by 112.69% and CH4 production increased by 87.11% at most. Both fracture interval and fracture number increased CO2 sequestration and CH4 production. However, when the horizontal well length was the same, the increasing of fracture number had a far greater impact on CO2 sequestration and CH4 production than that of fracture interval. When the number of fracture increased from 2 to 6. CO2 sequestration increased by 151. 92% and CH4 production increased by 137. 81% at most. Conclusions During the development process, strategically enhancing the half-length, height, width and quantity of artificial fractures can facilitate efficient sequestration of CO2 and extraction of CH4.
