铧式犁

Floor of entire county total ground accumulates 4885 square kilometer, climate characteristic is spring dry sand blown by wind is much, the summer is short rainfall is little, year average air temperature 2.5 ℃, fall 350mm is controlled, frost-free period is controlled 110 days, it is typical dry farming county, long-term since, because the ploughshare type of follow tradition plows cultivation, a large number of the earth's surface are completely bare, monsoon comes, soil land of medium fine sanded face is reached organic blow character, cause edaphic sand to change, fertility drops, raise of sand and dust, year answer a year, change dene serious with each passing day, cause aggravation of zoology environment year after year, the agriculture that also decided place produces a condition, groundwater source is not worth badly, 10 years of 9 drought, extensive cultivation, crop yield is low and flabby.

全县总土地面积4885平方公里，气候特色为春季干燥风沙多，夏季短促降雨少，年平均气温2.5℃，降水量350mm左右，无霜期110天左右，是典型的旱作农业县，长期以来，由于沿袭传统的铧式犁耕作，大量地表完全裸露，季风来临，将土壤中的细沙面土及有机质刮走，造成土壤沙化、肥力下降，沙尘扬起，年复一年，沙化日趋严重，造成生态环境逐年恶化，也决定了当地的农业生产条件，地下水源严重不足，十年九旱，广种薄收，作物产量低而不稳。

To solve the problem of transversal turnover of the paddy field boat during the cultivation operation, combining the method of theoretical calculation with paddy field test, the kinetic and dynamic characteristics were analyzed and the mathematical model was established according to movement stability in this paper.

为了解决机滚船犁耕作业转弯时的横向倾翻问题，采用理论计算与水田试验相结合的方法，通过对机滚船犁耕作业时的运动学和动力学分析，从稳定性角度出发，建立数学模型。经过分析和计算，求出了机滚船犁耕作业时最小转弯半径的关系表达式，将其运用到1BG-0.9型带铧式犁机滚船上，计算出了该机滚船的最小转弯半径。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
