Through reading critical power theory (CP: Critical Power) related domestic and foreign literature material, and against the characteristics of energy supplement in different distance, exploring the training methods of athletes' physical ability by using the dragon boat dynamometer. the research established related mathematical model between P-T; D-T; D-P; P-D−1. Research shows that: 1) P-T is nonlinear...
The signal transmission and measurement methods of the passive UHF radio-frequency identification (RFID) system are discussed in this paper. Parts of tag's communication performance, which conform to the ISO/IEC 18000-6 Type C, are obtained by using the software-defined radio test platform. The received power by the platform changes when the communication parameters vary. The measurement results show...
This paper introduces a small type of 180° Electronic Stripping Tester, taking single-chip microcomputer as a control core. Combined with mechanical design, the machine extends the control unit of the signal detection, LED display and motor control. It can test the quality of non-metallic products, such as the viscosity of adhesive tapes and the strength of woven belts. It can also test real-time...
Wet electrostatic precipitator (WESP) has been modernized over the last few decades. They were suitable for controlling slurry droplet, fine particles and acid aerosols. However, the applicability of current wet precipitators was badly limited for the imperfect mode of water film generation, back-corona, higher power consumption, corrosion of the collector surfaces. Tests were performed to investigate...
To evaluate braking performance of the vehicle scientifically and acquire directly described braking performance parameters of braking distance, horizontal displacement and yaw angle, the paper brings forward the method of testing braking track basing on dynamic measurements of braking wheel force solves the problem that can only rely on the road testing to get the braking track. The same pressure...
