The Chang’E-6 lunar mission successfully collected the back surface and subsurface regolith by excavating drilling returned samples to earth. Drilling–sampling system exhibits highly nonlinear characteristics due stratified structure of unknown physical property parameters, making it prone abnormal operating conditions sampling disturbances. Furthermore, constrained extraterrestrial environmental limitations, can only obtain health operational protocol status parameters while lacking direct...
<title>Abstract</title> Developing the relationship of pore characteristics and performance is vital for predicting properties pervious concrete. However, current prediction models mainly relied on porosity, ignoring influence other structure parameters, resulting in insufficient accuracy. The aim this paper to establish machine learning-based permeability compressive strength Firstly, six independent models, multiple linear regression Stacking algorithm were applied construct ensemble...
摘要: 嫦娥五号探测器通过表取和钻取的方式分别采集了表层和剖面月壤,并将月壤样品返回地球。月面钻进取芯过程的遥测数据直接反映了采样钻具与剖面月壤之间的相互作用状态,对其进行分析与解译能提高月面钻取采样任务的科学价值。基于嫦娥五号钻取采样装置的系统构成、工作原理和性能指标,从遥测数据中辨识出代表性钻进取芯工况。结合机-壤相互作用机理以及地面钻取采样试验数据,分析钻进取芯过程及其负载波动状态的月壤组构致因,并对全钻进剖面的月壤层序状态进行机理性解译。研究表明,嫦娥五号钻进点月壤剖面至少具有三个明显的层序结构,钻进剖面内存在着毫米级尺度月壤颗粒;钻取采样装置面对非确知月壤剖面已充分发挥其预定效能,并针对我国后续拟实施的星壤剖面采样探测技术做出了展望。
Direct-injection technology applied in hydrogen internal combustion engines can effectively prevent backfire, thereby improving the engine performance. Nonetheless, optimizing injection strategy is highly intricate, requiring a comprehensive understanding of hydrogen–air mixture formation process inside cylinder. In this study, simulation was systematically conducted direct-injection using three-dimensional computational fluid dynamics (CFD) software. Under rated conditions, influence nozzle...
<p indent=0mm>The Chang'e-5 mission of the third phase China's Lunar Exploration Program is first to sample and return from an extraterrestrial object. The objective was land on selected area lunar surface, collect samples, these samples earth safely through processes lift-off, orbit rendezvous docking, transfer, moon-to-earth reentry. This report describes mission's technical features, brief introduction, development process, summarizes breakthroughs innovation key technologies involved,...
For the existing problems of "information islands" in course construction digital campus, through research on software architecture SOA (service-oriented architecture), which has features standardization, loosely coupling, coarse grain, we propose integrated framework campus application integration based SOA, and give a specific combined with projects. The results show that it can effectively solve problem information islands implement data sharing interaction, furthermore, is easy to...
This paper analyzes the principle of operation, feature systems, contrast advantages and disadvantages two different systems which are Full-flow dilution sampling system (FFDSS) Partial-flow (PFDSS).This researches correlation this ways improving correlation. Many show that PM's test is below 10%.The PFDSS can replace FFDSS in special case. Some detailed suggestions to meet future requirements presented last paper.

A hybrid electric city bus was tested to explore its energy consumption and emissions under Chinese City Bus Cycle (CCBC) World Transient Vehicle (WTVC). Energy emission factors two cycles were compared. Contribution rates of different driving models gaseous studied. Results showed, CO factor CCBC higher than those WTVC, THC NOx lower. accelerating 3~4 times idle models, contribution more ten that models.
The complexity and particularity of Chang’e-5 unmanned lunar sample return missions have high demands for ground-test validation the probe. Test requirements cover multisystem levels, including large-system, system, subsystem, component levels. Several difficult ground tests are directed against key processes, such as sampling packaging, launching on moon, rendezvous docking, transferring in orbit, high-speed reentry. Here, we analyze features probe test each system level highlight testing...
