The multiple-factor analysis of dehumidification performance and flow resistance for the cross-flow membrane module was carried out based on the orthogonal test, guiding the structure optimization of membrane modules.

博士生秦思宇——以加快“新基建”5G基站布局为背景，开展了超薄蒸汽腔气液两相传热传质特性研究，探究内部瞬态沸腾和冷凝的相互干扰机制，并为超薄蒸汽腔传热性能强化提供优化方案。

With the background of accelerating the development of the 5G base-station for the "new infrastructure policy", the research on the gas-liquid two-phase heat and mass transfer characteristics of the ultra-thin vapor chamber was carried out. This study explored the mutual interference mechanisms of the internal transient boiling and condensation, and provided an optimization scheme for the heat transfer enhancement of the ultra-thin vapor chamber.

博士生马真迪——本研究提出了一个三维全尺寸的中深层套管地埋换热器计算模型，该模型包括了含水层和隔水层。通过分析发现中深层地埋换热器与含水层换热时，其取热能力增加，在两个隔水层之间产生了一个低温区域，从而导致地埋换热器的热性能与没有含水层相比发生了变化。

This study established a three-dimensional full-scale coaxial ground heat exchanger model containing both aquifer and aquifuge layers involving groundwater effect. The analysis indicates that the enhanced DBGHE heat extraction in aquifer causes a low-temperature gradient between two aquifuge layers, which changes the thermal behavior of DBGHE compared to that without the aquifer effect.

博士生李莹玥——针对我国村镇能源利用不合理，缺少科学规划等问题，提出村镇户级能源优选系统。该系统可以为村镇能源选择提供参考和指导。

Aiming at the problems of unreasonable energy utilization and lack of scientific planning in rural area in China, a rural household energy optimization system is proposed，which can provide guidance for energy selection in rural area.

硕士生邹岩卉——采用响应面法和遗传算法对不同结构的蛇形冷板进行结构参数优化，优化结果显示，最大温差基本不变时，压降最高可降低89.14%，为蛇形冷板的设计提供了指导。

The response surface method and NSGA-Ⅱ are applied for the structural optimization of serpentine channel with various configurations. The results show that while the maximum temperature difference basically remain unchanged, the pressure drop can be reduced by 89.14%. The proposed methods can provide guidance for the structural design of the serpentine cold plate.

硕士生杨昌明——本课题提出了一种新的 3D 均热板散热器模型。在实验测试的基础上，研究了不同作者提出的沸腾和冷凝相关式，提出了一种可以很好预测散热器传热性能的理论相关式模型。
