The two blades are fixed to constitute 45°(it adopts one special blade for cutting profile of professional picture frame) to cutting 45 degree profile, adopt German 13 hard alloy saw blades, imported guide rail, automatic cooling spray lubrication and hydro-pneumatic damper stepless speed regulation, thus it has high linear velocity and stable cutting angle, good surface finish, high precision and stable feeding.

采用德国成熟的设计理念结合最新的使用要求与习惯、针对用于38、50、65系列铝合金门窗料、镜框料以及新型隔热型材门窗料45度切割而开发，专业45度切采用两锯片固定构成45°（专业镜框料切割锯床采用一把专制刀具），对型材完成45°切割。选用德国13硬质合金锯片、进口导轨，线速度高，因而切割角度更加稳定、精确，自动喷油冷却润滑、气液阻尼无级调速装置，加工表面光洁度好，精度高、进给平稳。

The residues of 20% triazophos EC in rice field water, plant, rice shell and unpolished rice were determined by gas chromatography.

用气相色谱法测定了田间试验中20%三唑磷乳油在稻田水、植株、土壤、稻壳和糙米中的残留。

Greater flexibility has come with fuel injectors, which can metre fuel more precisely than carburettors, and variable-valve control, which can optimise the opening and closing of inlet and exhaust valves to produce more power when accelerating or greater economy when dawdling around town.

重要改进来自于电喷系统，它能比化油器更精确地控制燃料的喷射；以及可变气门系统，它能够优化发动机的进气和排起阀门的开启，让车子在加速时更有力而在低速运行时更省油。

At the same time, pattern recognition has been used for abstracting characteristics、predicting the life and evaluating the properties of engine. This research contributes toward global diagnosis for the diesel engine in eight ways.(1) Put forward"the Arithmetic of distinguish the period automatically using auto-correlation method";(2) Separate the waves of continuous knocks using WV distribution;(3) Propose"the logarithmic spectrum approximate method"to analysis the response of the knock between the steel and steel;(4) Discuss the relationship between the time-frequency distribution and timescale distribution in detail, and give the principle of classification;(5) Use the wavelet method to analysis the pressure signal of exhaust、suction;(6) Use the shape of vibration signal to analyse the working situation of cylinder;(7) Use the pattern recognition to select the good samples and abstract the effective characteristics;(8) Develop the model of total properties evaluation and life prediction.
