Study on Mechanical Automation with Cool-Starting Capacity of the Battery for Vehicles

It is advanced that cool-starting capacity of the battery is the key factor that affects the cool-starting performance of diesel engine. Cool-starting capacity of the battery is mainly affected by these factors,such as, the structure of the polar board, discharge electric current, temperature and density of the electrolyte. By optimally calculating the parameters above, optimal performance parameters of diesel engine at low temperature are received. Two performance tests of the diesel engine at low temperature,both Cool-Starting torque and starting rotate speed,are made on the basis of the cool-starting system of diesel engine,which completely satisfy the cool-starting requirements of the diesel engine at low temperature.

On the Difference Between Radio Loud and Radio Quiet AGN

Nuclear jets containing relativistic “hot” particles close to the central engine cool dramatically by producing high energy radiation. The radiative dissipation is similar to the famous Compton drag acting upon “cold” thermal particles in a relativistic bulk flow. Highly relativistic protons induce anisotropic showers raining electromagnetic power down onto the putative accretion disk. Thus, the radiative signature of hot hadronic jets is x-ray irradiation of cold thermal matter. The synchrotron radio emission of the accelerated electrons is self-absorbed due to the strong magnetic fields close to the magnetic nozzle.
