地面检测设备用于对载荷管理器的功能和性能进行检测，是载荷管理器研发中的重要保障设备。由于不同型号任务中载荷硬件接口和软件协议差异较大，载荷管理器地检的通用性一直是地检设备的设计难点。提出了一种面向星上设备，尤其是载荷管理器的基于配置文件的通用地面检测设备测试板卡设计。针对不同任务中载荷管理器电接口的物理层约定、通信机制和遥测遥控不同的难题，采用软件配置和硬件可重构的方法实现板卡硬件的通用设计。针对不同任务的科学数据和总线协议数据格式不同的难题，采用基于序列解析的数据包生成方法和超时接收方法实现软件协议、数据格式可配置。通过测试验证了所提出的通用地检测试板卡设计的可行性和通用性。

随着风电、光伏等新能源发电渗透率的不断提高，电力系统等效惯量水平不断下降且空间分布不均的特性日益凸显。而电力系统维持频率稳定的能力与系统等效惯量水平息息相关，因此明确电力系统等效惯量时空演变趋势具有重要意义。基于系统动力学模型，对电力系统等效惯量的时空演变趋势进行了分析。首先，明确新能源电力系统等效惯量概念及有效惯量组成，并分析惯量响应过程；其次，基于系统动力学模型，在考虑地域、技术进步率、综合成本等多因素影响下，对中国各地区光伏、风电、火电、水电、核电2025—2060年间的装机容量进行预测；最后，基于预测数据，对电力系统等效惯量时空演变趋势进行分析。所预测装机容量结果符合长期发展目标，计算所得电力系统等效惯量水平直观体现了在考虑虚拟惯量与否的情景下中国整体与各区域的变化趋势，可为规划各区域新能源发展，确定低惯量区域惯量补偿措施，保障频率安全等方面提供参考。

Most of the existing three-translation parallel mechanisms have more than one forward solution and are difficult to achieve precise and stable motion control. Therefore, a novel 3-RRPU parallel mechanism with three translational degrees of freedom was proposed, and the kinematics and dynamics and trajectory tracking control method of the parallel mechanism was researched. Firstly, by using the screw theory, the mechanism principle of implementing three translations was analyzed, and the drive input joints were chosen and demonstrated, and the characteristics of platform singularity, drive singularity, and branch-chain singularity of the parallel mechanism were analyzed. Secondly, the kinematics model of the parallel mechanism was built with the kinematics theory, and the forward and inverse position analytic solutions were derived. Thirdly, by using the Lagrange's dynamics theory, the rigid-body dynamics model of the parallel mechanism within the operating space was set up. Finally, a nonlinear feedback decoupled adaptive slide-mode trajectory tracking control method was proposed, and the stability of the trajectory control method was proved, based on the dynamics model of the parallel mechanism, the accuracy and drive moment simulations of the trajectory tracking control were implemented. The research results show that the mechanism has unique analytic forward position under general space configuration, and there are very few of the platform and drive singularity configurations of the mechanism and there is no branch-chain singularity configuration. The proposed trajectory tracking control method can enable the mechanism to achieve high-precision complex trajectory tracking of 0. 002 m under a load of 20 kg, a speed of 0. 18 m/ s, and an acceleration of 0. 12 m/ s², and especially, the trajectory tracking control method based on the Sigmoid function can effectively weaken chattering of the control moment, which provides new method for the implementation of three translational motions of high-speed, high-precision, and high-performance in the industrial field.

Actively exploring the infiltration and integration of labor education and professional courses is the requirement of teaching reform in the new era, and it is one of the ways to realize the fundamental task of moral education. Human and Animal Physiology is a compulsory course for biological science majors. We fully excavate the labor education elements of the course, and use field labor and participatory experimental courses to penetrate labor practice content. Exploring effective ways to integrate labor education into professional courses can realize the curriculum goal of combining knowledge teaching, skill training and value guidance, and guide students to develop in an all-round way.
