用实空间自洽场理论研究了二嵌段共聚物薄膜受限于平行板中的模板化自组装情况.通过改变平行板表面场修饰的情况，给出了粗略微观结构，观察了体系微相结构的变化过程，并对所观察到的变化规律作了讨论.另一方面，固定平行板的厚度、相分离强度等参数，改变吸附表面场的大小，观察并讨论了体系微相结构的变化及其规律.结果表明，二嵌段共聚物体系的微相结构是由受限条件和表面场修饰共同所决定的，因而控制表面场修饰情况的相关参数可以得到所期望的特定高分子体系结构.

In this paper, the structures and properties of PBT binder and TDI model compound were studied by density functional theory (DFT) method. The structures of PBT binder and TDI were optimized. The possible reaction sites of curing reaction were explored by calculating and analyzing the electrostatic potential energy diagram related to the electrostatic potential distributions of PBT and TDI. There are many reaction sites between PBT and TDI, which is easy to form network structures. Based on the model compounds, four possible curing reaction products were predicted, and the structures and energies of these products were calculated. The thermodynamic stable structure of the curing reaction was determined, and the most probable reaction pathway and activation free energy of the curing reaction were obtained by calculating the transition state of the most probable product reaction path. This study can provide a basis for further analysis of the aging reaction involved in PBT propellants. [ABSTRACT FROM AUTHOR]

OBJECTIVE: In recent years, a variety of new medical dressings have been used in the treatment of diabetic foot ulcer, and it is not clear which dressing has the best effect. Therefore, this study used network meta-analysis technology to systematically evaluate the efficacy of different new medical dressings in the treatment of diabetic foot ulcer. METHODS: A computer search was conducted on CNKI, Wanfang Data Knowledge Service Platform, VIP, China Biomedical Literature Database, PubMed, EM base, Cochrane Library, and Web of Science databases from the database establishment to November 2020. Randomized controlled trials of new medical dressings in the treatment of diabetic foot ulcer were included. The bias risk assessment tool of the Cochrane systematic evaluation was used to evaluate the quality of the included literature. Two researchers screened the literature and extracted relevant data. Rev Man 5.3, ADDIS 1.16.6 and Stata 14.0 software were used for literature quality evaluation and data analysis. RESULTS: A total of 33 randomized controlled trials involving 2 520 patients with diabetic foot ulcers were included, 10 of which were low-risk bias, 19 of which were medium-risk bias, and 4 of which were high-risk bias. Network meta-analysis results showed that (1) regarding the cure rate, the silver ion dressings, epidermal growth factor, platelet rich plasma, and amniotic membrane were superior to traditional dressings and alginate dressings; platelet rich plasma was better than that of the silver ion dressings; honey dressing was better than traditional dressings (P < 0.05). A probability results show that the top three dressings was platelet rich plasma, amniotic membrane, and epidermal growth factor. (2) In terms of healing time, silver ion dressings, epidermal growth factor and platelet rich plasma were al l better than traditional dressings and alginate dressings, and honey dressings were all better than alginate dressings (P < 0.05). The probability results showed that epidermal growth factor, platelet rich plasma and silver ion dressings ranked the third. CONCLUSION: (1) Based on the results of 33 randomized controlled trials confirm that in many new medical dressings, platelet-rich plasma, epidermal growth factor, amniotic membrane, and silver ion dressings are superior to other dressings in the treatment of diabetic foot ulcer. In the cure rate of diabetic foot, the best dressing was platelet-rich plasma. In terms of healing time of diabetic foot ulcers, epidermal growth factor ranked best. [ABSTRACT FROM AUTHOR]

Discussed the application of BHT in various fields, and summarizes the potential toxicity of BHT and its decomposition products to the environment and organisms. The results show that the antioxidant BHT has a wide range of applications in the fields of biomedicine, energy, food and material chemistry, and the design of a new antioxidant based on BHT can effectively expand its application range. Most of the degradation products of BHT proceed towards the direction of reduced toxicity, but the degradation products BHT-Q and BHT-tert-BuOH are more toxic than BHT. Studying the toxicity mechanism of BHT and its degradation products can reveal its metabolic differences and mechanism of action in different species, and can provide a theoretical basis for the application and modification of BHT.

The existent route convergence models are mainly deterministic ones, and various phenomena, such as packet losses, link noises, and sudden changes in interconnecting topology will occur in the route convergence process. Aimed at these random problems, a new stochastic dynamic system model was proposed by means of the Bernoulli white sequence distribution, the Wiener process and the Markov process. Based on the stochastic differential equation theory and the stochastic analysis methods, the sufficient conditions for the route convergence were given. The results prove that, the convergence of the routing state in a random environment is closely related to the Laplacian matrix of the router connection topology, the smooth distribution of the Markov switching, the successful transmission rate of the data packets, and the noise intensity in the network. Finally, a numerical example illustrates the effectiveness of the results. [ABSTRACT FROM AUTHOR]
