A verification of regressive models based on artificial neural networks and multiple regres- This paper provides an effective quantitative analysis system and verifies it. The system Of heart rate variability utilizes the reactions of the cardiovascular system for the duration of excitation. The paper analyses the qualitative record,,; of those signals of physiological reactions formed, such as heart rate variability, variation of blood pressure and some effective indexes in the time and frequency domains. The variation of the autonomic nervous system (ANS) is the fastest and most effective adjusting mechanism against the internal and external environment of a human body. Further, the heart rate variability (HRV) has the properties of non-invasion and ease and is able to determine quantitatively and differentiate the activities of the sympathetic nervous and the parasympathetic nervous systems. Through the experimental results, the activities of the sympathetic nervous and the parasympathetic nervous systems can display precisely the physiological comfortability with objective data by using the analytical instrument of heart rate variability. The comfortability of the bulletproof vest can be improved substantially by employing functional textiles such as moisture-absorbing, quick-drying, waterproof and breathable fabrics.
