For the first time given an "overweight" rating. 2010-2012 are expected to achieve revenues 1978.07,2594.49, 3404.03 million, respectively, an increase of 53.20%, 31.16% and 31.20%; net profit of 276.60, 245.11,331.66 million, respectively, an increase of 65.45%, -11.39%, 35.31%; respectively 20102012EPS0.67, 0.60,0.81 yuan, taking into account the nearly 2009 investment income 140.61 million dollars, is expected to profitability in 2010 (does not consider the company's return on equity) is significantly improved. The customer has noticed the advantage of green laser pointer price of this green laser pointer company.Shanghai University of Engineering and Shanghai Elevator laser heat treatment on the ductile iron, developed elevator positive roller V-groove surface laser enhancement technology has been accumulated to produce direct economic benefit of more than 12 million yuan. Ship repair Tianjin Institute of Technology for the shipbuilding industry of the compressor cylinder marine generator sets big modulus gear, marine host large-diameter cylinder, speed reducer gear intensive, also succeeded in solving the food machinery, large-diameter QT700-2 Crankshaft neck and eccentric journal of the laser hardening process. 9SiCr the critical point of the laser hardening 9SiCr steel: AC1, 770-780 ° C, ACm 870 ℃. 9SiCr steel using conventional quenching, the quenching temperature to 900 ° C, quenching hardness reaches a maximum value.
When the laser beam of Gaussian distribution in the heating process, experienced the highest temperature points, followed by B, C and D point almost, as a minimum. , C and D cooling rate in cooling the fastest, point B, followed by point A is the slowest. Three cooling rate in laser hardening is not the same organization that appears, shown in Figure 3. The diffusion coefficient D of carbon in austenite is a function of temperature where D0-basic diffusion coefficient, Q-diffusion activation energy, R-gas constant, T-thermodynamic temperature. In the laser heating process, the rate of diffusion of carbon in the distribution and temperature are the same. A high-temperature parts such as carbon diffusion speed. VCO supply VR7, which is a 2.8V voltage "soft" and "soft" in the program under the control of output voltage. Can be measured in the lower left of the VCO is a slightly larger a capacitor C655 to the test voltage in the boot and found VR7 voltage is 0V.
