Effect of activating device on the property of tap water was studied by surface tensiometer and pH meter. The results showed that the surface tension of tap water activated by the device reduced and pH value increased. The variations of surface tension and pH value are connected with flow rates. The larger flow rate, the less variation of surface tension and pH value when at the same cycle time, however, the more variation of surface tension and pH value when at the same activating time. Activated by the device, 17O NMR half width of tap water reduced from 70.79Hz at the inlet to 60.87Hz at the outlet. Reduction of surface tension were caused by hydrogen bonds in water clusters which were weakened or broken by far-infrared radiation of functional ceramic ball and galvanic cell action of copper-zinc alloy. Increment of pH value were caused by H+ in water exchanging with metal cations on surface of far-infrared ceramic balls and dissolved oxygen getting electron and forming OH-1 with the function of copper-zinc alloy.

Activated water is beneficial to healthcare due to its changes of physicochemical properties compared to ordinary water. Some related researches on activated water are reviewed in this paper. Take magnetized water, mineral and ceramic activated water and electrolyzed water for examples, activating materials and technologies are briefly introduced. Then, mechanism of activation devices and activated water are summarized and discussed. Finally, mechanism of activated water on biological growth is analyzed by comparing their different properties.

The dynamics equation of mobile welding robot is established. In controller design of the mobile welding robot, the non-holonomic constraint is introduced that limits the size of the transverse sliding and avoid the coordinates of the instantaneous center of rotation is larger than the wheelbase, to ensure the robot’s stability. Based on kinematics oscillator, the effect of uncertain dynamic parameters is considered. According to the Lyapunov stability criterion, the control algorithm is deduced. Simulating results by MATLAB software shows that the design of the control algorithm is stable, convergent and effective.

The effect of activated water on the growth of epidermal cells of newborn mice is studied by cell culture in vitro. To investigate the influence of activated water on the growth of cells, parameters of water are measured. Then, biological mechanism about how the water effects on cells is discussed. It shows that activated water has the promoter action to growth of cells comparing with non-activated water by detecting optical density (OD) at 570 nm with the MTT colorimetry. Statistically, the probability P, less than 0.01, is obvious. We believe that water cluster has become smaller and small water clusters are beneficial for transporting nutrients.

Influence of micro-environmental factors in animal breeding room on healthy growth of animal was discussed, such as harmful chemical gas, drinking water, microorganism, temperature, humidity and noise. Main products and technologies used in improving animal breeding micro-environment were summarized from four aspects including deodorization, activating drinking water, adding feed additives, using temperature and humidity control devices. At last, the development trends of micro-environment control were proposed in large-scale animal breeding.
