The present invention relates to a method for color measurement on printing materials produced by a printing press 1, using at least a first color measuring device 21 installed in the printing press and at least a second color measuring device 20. With the first color measuring apparatus 21 in the printing machine 1, when a color measured value measured with the material 9 to be printed is withina specific tolerable area for a specific tolerable area, a signal is given. When the signal is given one of the material 9 to be printed is taken out as one sample, and the color measurement is carried out with the color measuring apparatus 20.

The invention provides an NM600 high-strength wear-resistant pipe and a production process thereof. The NM600 high-strength wear-resistant pipe is characterized by comprising the following chemical components by weight: 0.69 to 0.75% of C, 0.20 to 0.40% of Si, 1.00 to 1.15% of Mn, no more than 0.025% of P, no more than 0.020% of S, 0.12 to 0.20% of Cr, 0.030 to 0.050% of V and no more than 0.010%of Al, with the balance being Fe and unavoidable impurities. According to the invention, the content of C is increased; proper V and Cr are added; the contents of sulfur and phosphorus are controlled;a high-temperature high-speed rolling method is employed; quenching treatment is carried out after rolling so as to obtain a martensite matrix structure; quenching stress is eliminated through low-temperature tempering treatment, so brittleness is reduced, and the structure reaches a stable state and can ultimately meet requirements on the mechanical properties of the NM600 high-strength wear-resistant pipe.

The invention provides a torque adjustment method of an adaptive cruise system of an electric vehicle, which relates to the field of automobiles. Including steps: use the adaptive cruise controller to calculate the expected acceleration, use the tire pressure sensor to detect the tire pressure p of the car tir The inclination sensor detects the vehicle mass M detected by the road gradient pressure sensor; the vehicle speed sensor detects the actual vehicle speed v(n); the acceleration sensor detects the actual acceleration of the vehicle and the human-computer interaction system inputs the driving environment information. The rolling resistance coefficient is obtained from the function of the relationship between the rolling resistance coefficient and the road surface and tire pressure. Realization of reference torque T by dynamic model fid (n) feedforward adjustment, plus adaptive PID feedback correction to get the desired torque T des (n). Switching the hold area enables effective switching between drive control and brake control, and ultimately adaptive cruise control. The invention shortens the adjustment time for stabilization to the final target acceleration and improves the stability of the system.
