The ratio of the number of tractors in good condition, the number of intact tractors, and the total number of tractors, expressed as a percentage.
Time Utilization Ratio The ratio of pure working time and total time per shift of the tractor in each shift, expressed as a percentage.
Tractor "armpit"
The tractor cannot work. Parking for more than two months is called "armpit."
Tractor productivity The amount of work per unit time in a tractor is usually expressed in terms of shift productivity (mu/shift), net working hour productivity (mu/h), and horsepower hour productivity (mu/hph).
Magnesium alloys have been paid more and more attention because of their unique properties and abundant resources. They have been regarded as environmental protection materials in this century. Has been widely used in the automotive industry, digital home appliances industry, ordnance and equipment manufacturers. Magnesium Alloy Plating is because of the abundant magnesium resources, especially in China's total 60%[4]. (2) the density of magnesium alloy is only about 1.73 of that of aluminum alloy, which is the first choice for the lightweight of the alloy, which is about 60%. (3) the magnesium alloy has high specific strength, good rigidity, easy cutting and molding. (4) the shock absorbing performance is good, can withstand the big impact vibration load, is suitable for the automobile steering wheel, the seat and so on the structural parts. (5) special electromagnetic shielding performance, suitable for mobile phones, computers and other electronic devices and biological protection. (6) good heat dissipation, is the preferred material for some functional devices 3C. (7) it is easy to recycle and is beneficial to the recycling of resources
