The Study on Landscape Architecture Rebuilding Design in City Wasteland

The paper illuminates the designed automatic weld control system. The RAC calibration arithmetic considering radial distortion is introduced, and according to the actual conditions of this weld system, the inchoate rapid calibration arithmetic is designed. Finally combined with the precision characteristic of the non-linear RAC calibration arithmetic and the concision characteristic of the inchoate rapid arithmetic, the improved automatic calibration arithmetic with six parameters is proposed, which achieves satisfied result.

Study on Measurement Method of Spark Energy for Automotive Engine

Spark energy is one of the most important parameters for SI engine, so it need be controlled effectively. Two modes of spark energy measurement were introduced in this paper: simulation load and direction measurement. 4 kinds of simulation load can be found: spherical discharger, three-pole discharger, Zener discharger and Zener string discharger, each has its own character. Zener string was chosen for it suited to electronic-controlled automotive engine. 2 kinds of direction measurement were introduced: attemperator, voltage and current sensor, the later was adopted for it can be realized easily and its precision characteristic. The test results show that the spark energy can be measured quantitatively and effectively in both modes; and the calculated spark energy of simulation load is larger than direction measurement for its less loss at the ignition circuit.
