Abstract： By analyzing the existing cellular automata theory and combining the characteristics of group evacuation, this paper establishes an ordinary supermarket fire evacuation model that considers the attractiveness of exit, fire repulsion, friction, repulsion and occupant psychology. The model fully considers the influence of multiple factors on the evacuation, normalizes the influencing factors, and uses the cell transfer intensity established by considering the comprehensive influencing factors as the pedestrian movement rule. This paper studies the impact of the number of evacuees in supermarket, export width and distance, and herd mentality on evacuation time. Pathfinder+FDS, a simulation evacuation software, is used to verify the model, which showed that the evacuation model has certain credibility. The research shows that pedestrian evacuation time is linearly and positively correlated with the number of evacuees, and there is a critical point for the number of evacuees; the wider the exit width is or the more exits are, the shorter the evacuation time is, but once the exit threshold is reached, the impact on the evacuation time is not significant; in unfamiliar environments or emergency situations, appropriate herding behavior will improve the efficiency of evacuation.

Abstract： The multi-objective unequal area facility layout problem (UA-FLP) is the problem of placing departments with different areas in a facility so that departments satisfy some given objectives and constraints. This paper built a multi-objective optimization model based on minimizing the material handling costs and maximizing the closeness rating scores, and proposed a heuristic algorithm (HA) to solve the multi-objective UA-FLP. This paper proposed the heuristic layout updating strategy to update the layouts, and used the combination of the local search based on the adaptive gradient method and the heuristic department deformation strategy to deal with the interface between any two different departments. The proposed heuristic algorithm combines the local search based on the Pareto optimization and the global search based on the niche爐echnology to obtain Pareto-optimal solutions of the problem. Using two representative instances from the literature to test the performance of the algorithm, the experimental results show that the proposed heuristic algorithm is an effective method for solving the multi-objective UA-FLP.

Abstract： The water level changes of grassland lakes indicate the changes of grassland ecological environment,which is an important indicator of grassland ecological changes. We use the ATL13 global inland water data ofICESat- 2 satellite from November 2018 to January 2022 to construct a high- precision water level changesequence of Hulun Lake. The results are verified using DAHITI, Hydroweb, and G-REALM water level data.Based on the relationship between lake area and water level change, a water level area relationship model isconstructed to analyze the seasonal characteristics of lake water level changes and the influence of externalfactors on lake water level. The research results showed that: from November 2018 to January 2022, the waterlevel of Hulun Lake showed an overall upward trend, with an average annual water level rise rate of 0.49 m·a-1.The water level of the lake decreases from March to June each year, rises from July to October, and stabilizesfrom November to February of the following year. It is known from the comparison and verification withDAHITI, Hydroweb, and G-REALM water level data that the ICESat-2 satellite monitoring water level data isstable, the water level sequence precision is high, and the root mean square error is 9.7 cm, which is reliable. TheCombination of the ICESat-2 satellite water level monitoring results and the lake water level area model canachieve multi-time and high- precision lake water level monitoring, and calculate the time series of water levelseasonal changes, which showed that the seasonal characteristics of Hulun Lake water level are obvious, and theinter annual trend is basically stable. The water level decreases from spring to summer and rises from summer towinter. The changes of lake water level is greatly affected by external factors. The increase of evaporation causedby the rise of temperature is the main factor leading to the decrease of lake water level. The temperature,evaporation, and water level change showed a strong negative correlation. The recharge of the lake water volumeby artificial water injection has increased the lake level and the trend of increasing water level is obvious duringthe injection period in 2021.

Abstract： 0Cr16Ni5Mo steel is the most popular material used for fasteners and bolts in the marine engineering equipment. With the light weight trend of equipment, the strength grades of the steel become higher. 0Cr16Ni5Mo steel combines high strength, high hardness and high fracture toughness with good ductility. However, high strength steel is prone to degradation by hydrogen, resulting in the loss of its excellent mechanical properties. And the presence of diffusible hydrogen near a notch tip is easily to cause crack propagation. The susceptibility to hydrogen embrittlement of steel is largely determined by the hydrogen diffusivity and the behaviors of hydrogen trapping in the steel. Therefore, the hydrogen trapping behaviors of 1000 MPa grade 0Cr16Ni5Mo steel have been investigated by means of thermal desorption spectroscopy (TDS). Meanwhile, the hydrogen embrittlement susceptibility of the notch and smooth specimens was evaluated by slow strain rate tests (SSRT), and the fracture morphology was also observed. The results showed that the main hydrogen traps of experimental steel was contained dislocations and grain boundaries. The elongation of hydrogen charged specimens was decreased obviously rather than tensile strength. With the increase in hydrogen concentration, the fracture surfaces of hydrogen charged specimens was displayed a transition from ductile microvoid coalescence to a mixed morphology of dimples, quasicleavage and intergranular features. The steel had little irreversible hydrogen due to less C content, and had much susceptibility with reversible hydrogen contained. The model of hydrogen induced stress was calculated on basis oEshelby equivalent inclusion, validating the relationship between stress concentration and hydrogen concentration.

Abstract： Objective: To explore the clinical effect of tumescent technique in early operation of massively burned patients. Methods: A retrospective cohort study was conducted on 27 patients with large area burns accorded with the inclusive criteria and admitted from June 2019 to November 2022. Among them, 14 patients admitted from June 2021 to November 2022 were treated with intraoperative injection of tumescent fluid for hemostasis and were rolled in tumescent group, or observation group; 13 patients admitted from January 2019 to November 2021 were treated with tourniquet for hemostasis were rolled in tourniquet group, or control group. The operation time, blood loss, blood preparation, blood transfusion, preoperative and postoperative hemoglobin, intraoperative and postoperative blood pressure, heart rate, postoperative skin graft survival rate and other related indicators were compared between the two groups, and the clinical effects were observed. Results: There was no statistical difference in preoperative blood volume between the two groups (p > 0.05). The actual amount of blood transfusion in the observation group was less than that in the control group, and the difference was statistically significant (p < 0.05). The intraoperative blood loss and operation time in the observation group were significantly less than those in the control group, and the difference was statistically significant (P < 0.05). There was no statistical difference in preoperative and postoperative hemoglobin between the two groups (p > 0.05). The survival rate of skin grafting in the observation group were slightly higher than those in the control group, and the difference was statistically significant (P < 0.05). The vital signs of patients in the observation group were more stable than those in the control group, and the difference was statistically significant (P < 0.05). Conclusion: Tumescent technique can reduce the amount of intraoperative blood loss, shorten the operation time, improve the survival rate of postoperative skin grafting, and ensure the stability of intraoperative hemodynamics in early operation of massively burned patients.

Abstract： 紫花苜蓿是我国重要的豆科牧草，具有较强的抗旱能力，而水分亏缺是影响其产量的主要逆境因子之一。通过大田试验对不同水分胁迫下紫花苜蓿的光合特性及产量进行研究，结果表明：① 土壤水分胁迫对紫花苜蓿光响应参数影响显著(P＜0.05)，随着水分胁迫的加剧，最大净光合速率、表观量子效率、光饱和点逐渐降低，暗呼吸速率、光补偿点逐渐升高，从而直接影响紫花苜蓿光合作用对弱光的吸收和转化效率。② 随着水分胁迫的加剧紫花苜蓿叶片的净光合速率(Pn)和蒸腾速率(Tr)呈显著的下降趋势，气孔导度(Gs)呈先下降后上升的趋势，表明轻度水分胁迫下气孔因素是Pn下降的主要因素，中度和重度水分胁迫下非气孔因素是Pn降低的主要因素。③ 当光合有效辐射(PAR)为1 200 μmol·m-2·s-1时，轻度水分胁迫的水分利用效率(WUE)显著大于充分灌溉的WUE (P<0.05)，表明适度水分胁迫可提高紫花苜蓿叶片的水分利用效率。④ 轻度水分胁迫与充分灌溉干草产量之间无显著差异，表明轻度水分胁迫能达到高产节水的目的。

Abstract： Epimedium sagittatum plants have an important medicinal value and a huge market demand, but the characteristics on dormancy and germination of their seeds are still unclear, which seriously affect its industrial seedling production and cultivation. In order to verify the type of seed dormancy and the optimal way to break dormancy, the mature seeds of E. sagittatum were used as experimental materials, we investigated the water uptake and the desiccation tolerance of seeds, as well as the effects of temperature, stratification and phytohormone on seed dormancy and germination. The results were as follows: (1) E. sagittatum seeds had no physical dormancy and (2) Have desiccation tolerance. (3) The germination percentage of seeds was zero at 4-25 篊 and darkness, and these seeds had dormancy characteristics. (4) The embryo/seed ratio was very small, as well as embryo growth and development and seed germination rate and germination percentage were increased by stratification at 4 篊, 10 篊 and fluctuating temperature.(5) Gibberellin and fluridone significantly increased the germination rate and germination percentage of seeds. We considered that the dormancy type of E. sagittatum seeds was morphophysiological dormancy. The optimal method to release dormancy and promote germination was that seeds were stratified at 10 篊 for 30 days and then germinated at 4 篊.
