Environment Analysis with Temperature Change in Jarud in Recent 59 Years Chun hua1, a, Tuya Alateng 2,b 1College of Geographical Science, Inner Mongolia Normal University, Huhhot City, Inner Mongolia,China010022 2Inner Mongolia Key Laboratory of Remote Sensing and Geograghy Information System, Huhhot City, Inner Mongolia,China010022 a394606261@qq.com, baltty@imnu.edu.cn Keywords: Jarud; Temperature; accumulated variance analysis;China Abstract: By means of the linear trend analysis and accumulated variance analysis, the climate change characteristics of temperature from 1953 to 2011 in Jarud Banner were analyzed.
Thus, the temperature for annual, and seasonal were analyzed in detail to better understand the variation characteristic of temperature in Jarud Banner, in order to provide reference and guidance for the development of agriculture, and early warning of severe weather in Jarud Banner. 2.Materials, methods and Study area 2.1Materials and methods The average temperature date were from meteorological observation station of Jarud Banner during 1953-2011.

With the development of science technology and the improvement of manufacturing technology of shearing machine, and the demand expansion to the diversity of shearing machine, we can predict that the update and intelligent speed of shearing machine will also be speeded up.
From the literature we can see that most people pay attention to the discussion of structure design, manufacturing craft and material selection, but little discussions about the detailed mechanical analysis is done.
