全/半桥子模块混合型模块化多电平换流器（modular multilevel converter，MMC）由于具备直流故障穿越能力并兼顾了制造成本，成为当下柔性直流输电领域的研究热点之一。全桥子模块具备负电平输出能力，混合型MMC可以提升电压调制比，运行在过调制状态，提升运行效率。但是混合型MMC在过调制运行工况下的电流、热应力分布特性尚不明晰，为此针对混合型MMC在过调制下的全/半桥子模块开关器件的电流应力及热应力展开研究。通过分析混合型MMC在过调制下的工作原理和特性，结合仿真着重研究了不同电压调制比以及不同功率因数下换流器的损耗分布特性；归纳出了直流电流调制比的概念。研究发现随着直流电流调制比的增大，子模块内部开关器件的损耗—热应力分布不均程度加大，危及MMC安全运行，结论可以为混合型MMC的设计和优化提供指导。

Objective　To investigate the clinical efficacy of continuous renal replacement therapy (CRRT) in patients with severe burn sepsis. Methods　Forty patients with sepsis caused by severe burns who met the inclusion criteria and were admitted to the Department of Burns of the Second Affiliated Hospital of Kunming Medical University from January 2020 to January 2023 were retrospectively analyzed. According to the treatment, patients were divided into control group and treatment group, with 20 patients in each group. The control group was given conventional symptomatic and supportive treatment, and the treatment group was given continuous renal replacement therapy on the basis of conventional treatment. The venous blood of the control group and the treatment group was taken before treatment and 24, 48, 72 hours after treatment. White blood cells ( WBC), calcitonin (PCT), serum creatinine (Scr), blood urea nitrogen (BUN) level. In addition, the length of hospital stay and the total cost of hospitalization were compared between the two groups. Results　Before treatment, the levels of C-reactive protein ( CRP), interleukin-6 ( IL-6), white blood cell ( WBC), procalcitonin ( PCT), serum creatinine (Scr) and blood urea nitrogen (BUN) in the two groups were compared, the P value was above 0.05, and the difference was not significant in the statistical data. 72 hours after treatment group C reactive protein (CRP) and interleukin 6 ( IL - 6), white blood cell ( WBC), calcitonin ( PCT), serum creatinine ( Scr), blood urea nitrogen (BUN) level, the results show that numerical value was lower than the control group, experimental group and the difference between the P value is less than 0.05, has significant statistical significance. In addition, the length of hospital stay and total hospital costs were also statistically lower in the CRRT group than in the usual care group. Conclusion　In severe burn patients with sepsis, continuous renal replacement therapy has a significant effect, which can effectively remove inflammatory mediators, prevent and treat uncontrolled inflammatory response, and effectively relieve the symptoms caused by systemic infections such as burn wound sepsis. It has a good application prospect in the prevention and treatment of stress injury and organ injury caused by sepsis in clinical practice. At the same time, it can also bring certain economic and social benefits. [ABSTRACT FROM AUTHOR]

[Objective] The study aims to explore the influence of sowing date on the yield and quality of waxy corn varieties, so as to provide theoretical basis and technical guidance for the production practice of waxy corn in South China. [Method] The study adopted a two-factor split area design, with 2 sowing dates (August 15 and August 25) and 5 varieties (Yueheitiannuo 1, Yuecaitiannuo 5, Yuecainuo 2, Yuebaitiannuo 12, Yuebaitiannuo 168) as the treatment factors, and investigated the growth period, plant height, ear length, yield and quality of fresh waxy corn. [Result] With the delay of the sowing date, the whole growth period of the autumn sowing waxy corn is gradually extended. The whole growth period of the five varieties was extended by 13, 11, 10, 11 and 12 days, respectively, among which the extension period was mainly reflected in the vegetative growth stage to tasseling stage. Except for ear length and ear size, the delay of sowing date increased the plant height, ear position height, stem size, fresh weight, ear weight, baldness, ear number and grain number of waxy corn, but at the same time, the quality and yield showed a downward trend. The yield of Yuecaitiannuo 5 increased by 32% with the delay of sowing date, while the yield of Yueheitiannuo 1, Yuecainuo 2, Yuebaitiannuo 12 and Yuebaitiannuo 168 decreased by 11%, 5%, 9% and 4%, respectively. In addition, the correlation analysis can show that the effective accumulated temperature of the whole birth period around 1200 ℃·d is more conducive to ensuring a higher harvest index and then obtaining a high yield. Meteorological factors also have a significant influence on the yield of waxy corn. Among them, the daily average temperature corstrongly correlation with yield, and the correlation coefficient between the two is 0.932, which is the main meteorological factor affecting the yield of fresh waxy corn. Accordingly, This indicates that in the autumn waxy corn production, it is necessary to pay attention to the monitoring and prediction of meteorological conditions to develop better develop agronomic measures and improve yield and quality. [Conclusion] The influence of waxy corn yield and quality is mainly reflected in the emergence to the male, during this period, waxy corn to higher temperature requirements, if the temperature is too low will lead to its nutritional growth period, growth rate and cause production, in waxy corn production, choose suitable for yield and quality has important role, Autumn waxy corn in South China is suitable for sowing around August 15.

In view of the low assembly rate of high pile wharf, the beam assembly type of high pile wharf was proposed for the first time, and the mechanical properties were studied by numerical method combined with the load model extracted from the typical working conditions of high pile wharf structure. According to the results of the simulation analysis, the wharf structure with the I-steel assembly beam on the pile cap can meet the strength and deformation requirements of the wharf structure under a variety of load combinations; the I-steel is mainly subjected to horizontal shear action, and most of the uplift action is shared by the structure weight; the reinforcement near the I-steel is under great stress, so local reinforcement should be considered in the design. The research results provide a new idea for the design of prefabricated high pile wharf, and can provide reference for the design of similar projects. [ABSTRACT FROM AUTHOR]
