试车台氧化剂系统增压能力影响因素分析

试车台进行改造后,管路和容器参数都发生了变化,试车过程中需在要求时间内完成发动机氧化剂入口压力从前稳段升压至过载段。首次试车过程中由于贮箱增压计算出现误差,导致氧化剂升压过程中增压阀门多次动作。为避免升压过程中增压阀门的多次动作,获得试车台的实际增压能力,对其影响因素及试车数据进行了分析,修正了调整计算过程。试验结果表明:调整计算正确,改进措施有效,满足了试验任务要求。     

Spatial Thinking in Undergraduate Science Education

Spatial thinking is central to many scientific domains and professions spatial ability predicts success and participation in science. However spatial thinking is not is not emphasized in our educational system. This paper presents a selective review of four types of studies regarding spatial thinking in undergraduate science curricula; (1) correlational studies examining the relations between measures of spatial ability and performance in science disciplines, (2) studies that attempt to train aspects of spatial thinking, (3) studies of how students understand specific spatial representations in sciences (4) studies that use dynamic spatial representations to promote scientific understanding. For each type of study, the evidence is critically evaluated and conclusions are drawn about how to nurture spatial thinking in science.

Predicting performance in manually controlled rendezvous and docking through spatial abilities

Manually controlled rendezvous and docking (manual RVD) is a challenging space task for astronauts. This study aims to identify spatial abilities that are critical for accomplishing manual RVD. Based on task analysis, spatial abilities were deduced to be critical for accomplishing manual RVD. 15 Male participants performed manual RVD task simulations and spatial ability tests (the object-manipulation spatial ability and spatial orientation ability). Participants’ performance in the test of visualization of viewpoints (which measures the spatial orientation ability) was found to be significantly correlated with their manual RVD performance, indicating that the spatial orientation ability in the sense of perspective taking is particularly important for accomplishing manual RVD.
