In this report, we intended to clarify the effect of floor hating system for accessing a peripheral leukocyte regulation in winter season by evidence-based manner more than VAS. We set up two different office rooms heat-controlled by floor heating and air-conditioned by ceiling electric heater. Both qualitative and quantitative approaches determine which are better therapeutic effective recipes for this trial. The elements were evaluated by the total number of peripheral leukocyte, granulocyte and lymphocyte ratio and lymphocyte subsets. For 5 days of working in each conditioned room, the volunteers were changed the room after one-week interval for cooling down. Floor heating system regulated total number of peripheral leukocyte. The mode of the action for the high number of the volunteer was down-regulated. On the contrary, in lower numbers it was up-regulated after the trial. The number of leukocyte subsets, granulocyte and lymphocyte were also regulated by dose dependent manner. Emotional hormone, adrenalin, cortisone and nor-adrenaline were down regulated by floor heating but dopamine was up-regulated by this heating system. The reversal results were obtained by the group who worked in the conditioned room by the system heating from ceiling.展开更多

According to the characteristics of the actual air flow and temperature change in gob, a two-dimensional temperature field model of the gob was built, and the relational model between the air pressure of intake and outlet of the gob and the atmospheric pressure was established, which was introduced into the boundary conditions of temperature field to conduct calculation. By means of analysis on the simulation example, and comparison with the traditional model, the results indicate that atmospheric pressure change had notable impact on the distribution of gob temperature field. The laboratory test system of gob temperature field was constructed, and the relative error between simulated and measured value was no greater than 9.6%, which verified the effectiveness of the proposed model. This work offers theoretical basis for accurate calculation of temperature and prediction of ignition source in mine gob, and has important implications on preventing spontaneous combustion of coal.展开更多

The li near errors and high order errors of a sensor (especially piezoresistive sensor) can be corrected by using this system. It can optimize the process of piezoresi stive sensor calibration and compensation, then, a total error factor within 0.2 % of the sensor′s repeatability errors is obtained. Data are recorded and coeff icients are determined automatically by this system, thus, the sensor compensati on is simplified greatly. For operating easily, a wizard compensation program is designed to correct every error and to get the optimum compensation.展开更多
