MICROGRAVITY EXPERIMENTS OF TWO-PHASE FLOW PATTERNS ABOARD MIR SPACE STATION

A first experimental study on two-phase how patterns at a long-term, steady microgravity condition was conducted on board the Russian Space Station 'MIR' in August 1999. Carbogal and air are used as the liquid and the gas phase, respectively. Bubble, slug, slug-annular transitional, and annular hows are observed. A new region of annular how with lower liquid superficial velocity is discovered, and the region of the slug-annular transitional flow is wider than that observed by experiments on board the parabolic aircraft. The main patterns are bubble, slug-annular transitional and annular flows based on the experiments on board MIR space station. Some influences on the two-phase how patterns in the present experiments are discussed.

SJ-10 Recoverable Satellite for Space Microgravity Experiments

SJ-10 is a recoverable scientific experiment satellite specially for the space experiments of microgravity physics science and space life science.This mission was officially started on 31 December 2012,and the satellite was launched on 6 April 2016.This paper introduces briefly the SJ-10 mission,the progress of SJ-10 engineering and the project constitution of sciences experiments onboard SJ-10.The purpose of this mission is to discover the law of matter movement and the rule of life activity that cannot be discovered on the ground due to the existence of gravity,and to know the acting mechanism on organisms by the complex radiation of space that cannot be simulated on the ground.

China's Space Animal Experiments Obtained Achievements

Entering into the 1990s, Chinese scientists have made mice, drosophila and silkworm eggs experiments in space with satellites and achieved remarkable results. These animals were put in space environment units with the ability of adjusting pressure, temperature and moisture control, air conditioning and purifying as well as foods and water supply. After 8-days’ flight, all performance parameters were normal and met the design requirements. The two mice kept alive for 5 days and 10 hours

Advances in China Space Medical Experiment Research

In 2021,China Space Station(CSS)was assembled and constructed in-orbit,which provided a broad space platform for space medicine and space life sciences research.Space medicine focuses on the systematic risks that restrict long-term manned spaceflight.It carries out systematic research on the impact and countermeasure technology of long-term weightlessness on astronauts’health,space radiation on astronauts’health,behavior and ability,advanced on-orbit monitoring and medical disposal technology,and traditional space medical application technology by the space medicine experiment platform on human body and cell.It has accumulated valuable data on space environmental effects and human factors research,established a“human system risk”research system,obtained new knowledge and discoveries of space medicine,and explored countermeasure technologies of new characteristics.Moreover,a series of achievements have been made in the basic research on the mechanism of the special space environmental effect,which provides a solid foundation for the implementation of space missions.

Design of Cultural Experience Space From the Perspective of Ecological Aesthetics:A Case Study of Aixi Lake Beauty·Library

Ecological aesthetics is the organic combination of ecology and aesthetics.It is the mainstream and basic form of aesthetics to integrate the ecological concepts of balance,system and entirety into the study of aesthetics.Cultural experience space is a new reading space with the characteristics of public cultural services.In this paper,Aixi Lake Beauty·Library is taken as research object,to analyze its design connotation and public effect from the perspective of ecological aesthetics.The research aims to explore a feasible way for the construction of urban cultural experience space.

Reflections on the Experience of Network Virtual Space FromPhenomenology of Technics

People create network virtual space that is completely different from the real space through network information technologies.The characteristics of network virtual space are that the subject can obtain a similar real space experience.From the perspective of phenomenology of technics,in order to analyze the virtual space of the network,it is necessary to clear the phenomenological concepts,such as space,space experience,and virtual space experience,so as to know the type of network virtual space experience,explore the essential characteristics,and find solutions to the ethical conflicts in the virtual space experience of the network.

Physiological responses of people in working faces of deep underground mines

The research studied the influences of high temperature, high pressure, high humidity, noise and other harmful factors in mining conditions on the people health and safety, and investigated the impacts of confined environmental on human physiology factors, including temperature, humidity, noise, pressure,toxic and harmful gases in terms of environmental characteristics in underground mines and an artificial intelligence system for simulation of the environment in a confined space of deep mines. Our results show that the systolic pressure, diastolic pressure, mean pressure, heart rate, respiratory rate, typing test speed and memory level percentage are negatively correlated with temperature value, and positively correlated with humidity value; the human temperature and weight are positively correlated with temperature value, and negatively correlated with humidity value. This research lays the foundation for the study of interaction between the deep confined space environment and safety behavior.

Experiment of the Two-phase Flow Pattern in Different Gravity Environment on Board the MIR Space Station

In accordance with the agreement entered into by China and Russia on the utilization of 'Mir' space station for development of cooperative research in April 1998, the Institute of Mechanics, CAS and Keldysh Research Center of Russian Space Agency accomplished the experiment of two-phase flow pattern in different gravity conditions aboard 'Mir' space station and gained a complete success after more than one year of research and cooperation. In this cooperative research, the Chinese side is responsible for presenting the aca-
