ABSTRACT
Based on the principle of thermal physiology, especially on the effect of the ambient temperature on head-neck skin temperatures, the paper discussed some general problems about detecting the suspected patient of SARS from large number of transferring people in public place according to the head-neck skin temperature during recently fight against SARS. Therefore several suggestions about how to improve and ensure the effectiveness and security of such detection were put forward.

OBJECTIVE: To study effect of simulated weightlessness on non-evaporative heat dissipation from different parts of the human body. METHOD: Body surface temperature distribution of five subjects was measured under -6 degrees head down bedrest for 7 d with HR-II infrared thermography. Non-evaporative heat dissipation was calculated with the heat exchange equations based on surface temperature. RESULT: The temperature difference between torso and extremities increased during bed rest, and the largest was 6.7 degrees C higher than the control on the 3rd day of bed rest. The part of non-evaporative heat dissipation from the torso increased about 6% and that from head-neck increased 2%. At the same time, the parts of heat dissipation from the upper and lower extremities decreased about 3% and 5% respectively. CONCLUSION: The parts of non-evaporative heat dissipation from different areas of the human body changed during simulated weightlessness. This result provided a basis for the flow distribution design of liquid cooling garment of EVA suit.
