2, long-term pedal clutch pedal. Some operators are accustomed to pedaling on the clutch pedal while driving in a locomotive. The harm is that the locomotive will oscillate along uneven roads, which will cause the clutch to be in a half-coupled state, affecting the engine power transmission and accelerating clutch friction. The sheet wears.
3. Start the engine with inertia. Some drivers use the high speed to stop the clutch to slide. When the speed is high, the clutch lifts the inertia of the vehicle to start the engine. It is very easy to damage the components of the drive train and it is unsafe to inject the engine with excessive load.
4, throttle instead of speakers. When some drivers encounter pedestrians while driving, they do not use the horn to slow down. Instead, they use powerful throttles to make way for pedestrians. This will cause the engine to emit heavy smoke and pollute the environment. Suddenly increasing the speed increases mechanical wear. It is easy to cause traffic accidents.
5, the vehicle does not pick off block. Some pilots do not use neutral gear when the vehicle is taxiing. Instead, they place the gearshift lever in the high gear position. The clutch is used to cut off the transmission with the engine and the vehicle is coasted. This will intensify the wear of the clutch release bearing, and it will not be permitted in safe operating procedures to depress the clutch for a longer period of time downhill.
6, after the start and turn off the throttle before the flame. The compression ratio of diesel vehicles is larger than that of gasoline vehicles. Suddenly increasing or decreasing the throttle can easily cause the connecting rod and the crankshaft to deform or break, increase the carbon deposition in the cylinder piston, and accelerate the wear of moving parts.
7. Kill the steering wheel in place. Some drivers used the method of deadly driving the steering wheel when they were stationary in order to turn the vehicle into position. This would not only violate the operating rules, but also make the components of the steering mechanism easily damaged.
Safflower yellow can significantly inhibit ADP-induced platelet aggregation in rabbits, and also has a very obvious depolymerization effect on ADP-aggregated platelets. When the dosage was 0.22g/ml, the inhibition rate of aggregation and depolymerization reached 85.9% and 78.9% respectively. These effects of safflower yellow were enhanced with the increase of dosage. Safflower yellow has a very significant inhibitory effect on experimental thrombosis in rats, the inhibition rate is 73.4%. Because the thrombus material formed on the silk line is platelet aggregates, the reduction of wet weight of thrombus is obviously the result of drug inhibiting platelet aggregation. It is consistent with in vitro experiments that safflower yellow can inhibit platelet aggregation induced by ADP. Safflower yellow also significantly prolonged plasma recalcification time, prothrombin time and coagulation time in rabbits. It shows that it can affect the coagulation system both in vivo and in vitro. In addition, safflower oil can reduce blood lipid.
