Physiological Variations

1. In the eel (Anguilla anguxlla L.), the dorsal and ventral aortas and the subhepatic vein were catheterized to provide an external circulatory shunt. POO2 in the shunted blood was continuously recorded using a polarographic measuring device. 2. Spontaneous interruptions in the eel's ventilatory activity result in rapid changes in Pα, Oα, O2. The period of these Pα, Oα, O2 oscillations is sometimes less than 1 min. However, the response time of the measuring system is so great under the conditions of these experiments that only slow variations of Pα, Oα, O2 of a period greater than 5 min, are faithfully recorded. 3. In view of the impractibility of technical improvement in the recording system, a data processing method was developed to reconstitute the real physiological variations from the distorted experimental recordings. 4. Through this method of data correction, it is demonstrated that apnoeic or active ventilatory phases in the eel's breathing pattern are not triggered by constant low values of Pα, Oα, O2. Other physiological applications are suggested. Note: Equipe de Recherche Aasociee du Centre National de la Recherche Scientifique n 070623

Measurement And Control

This paper presents the composition and working principle of the hardware and software of the measurement and control system based on VeriStand and Simulink for a tracked model vehicle. The hardware of the system is composed of a CompactRIO controller and acquisition cards, torque/speed sensors and a gyroscope. The vehicle control logic model and data processing model are built in Matlab/Simulink. VeriStand is adopted to manage models and interact with people. The system can control motor speed on both sides of the vehicle and collect data such as sprocket torque and speed, vehicle attitude on real-time. At last, we test and verify the system can work successfully.

Explosively Formed Projectile (EFP) is a new branch of the shaped charge technology. It is developed as an anti-solid target technology in recent decades. Velocity of EFP changes quickly with the change of EFP shape. It is very important to research the velocity and morphology change of EFP in their movements to improve its performance. In this paper, theory of the exploding forming effects of EFP is analyzed, the working principle and design process of the EFP test system are introduced, and a particularly detailed description of the structures is given. The way of assembling test system and the process of data processing in the experiment are described. The experiment result shows that this system has a bright application future in the area of the EFP test, and it is worthy to further study.
