After contrasting and optimizing this paper gets a set of parameters. Then according to these parameters the paper sets up entity model, and after validating and analyzing with finite element it can save time of calculating. On the other hand, it can provide a good method of design of moldboard plow surface.

通过对这四个阶段中土垡的运动学和动力学分析研究，建立了犁体牵引阻力的数学模型；通过对比分析得到较优的一组参数，然后以该组参数为依据进行参数优化，最后以优化后的参数建立犁体实体模型，应用有限元进行分析，节省了计算时间和提高了计算效率，为今后犁体曲面设计提供了一种方法。

This benefit was obtained by using a moldboard plough to prepare the soil in the pre-monsoon period in June.

这种好处由6月季风季节之前用有壁犁整地翻耕得到，然后土地在季风季节休闲直到11月种麦。1983年有壁犁耕翻（30厘米深）的效果与深松犁（45厘米深）、凿形犁（25厘米深）和农民的播种机（10厘米深）加以比较，只有有壁犁的效果明显好于播种机（Khan等，1986）（图1）图1。

A plow equipped with a double moldboard that turns up the soil on each side of the furrow, often having an attached drill for seed planting.

双壁开沟犁犁头后部有两块曲面铁板的犁，可翻开犁沟两边的泥土，常附有播种机注意，注意力集中

A plow equipped with a double moldboard that turns up the soil on each side of the furrow,often having an attached drill for seed planting.

双壁开沟犁犁头后部有两块曲面铁板的犁，可翻开犁沟两边的泥土，常附有播种机那个农民将牛缚在犁上，用刺棒驱赶它们。

This paper makes the soil movement be four sections: a Cutting soil with edge; bThe soil movement along the plowshare and plow chest's below surface; c The soil movement along the plow cliff ;dThe soil movement beyond the plow in the course of farming in order to study the force of moldboard plow surface.

本文在研究犁体曲面受力时，把犁耕时土垡的运动分为四个阶段：a 用铧刃切开土垡；b 土垡沿犁铧和犁胸下部曲面运动；c 土垡沿犁壁运动；d 土壤超出犁壁曲面运动。

Shuangjian licensing plow shovel high quality and low price, I produced Shuangjian licensing Road mill with plow shovel manufacturing, licensing Shuangjian plow shovel as sharp as the sword, tenacity wearable, Shuangjian plow shovel is your best option.

双剑牌犁铲质优价廉，我公司生产的双剑牌犁铲用道轧钢制造，双剑牌犁铲像剑一样锋利，坚韧耐磨，双剑犁铲是您最佳的选择。

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。

Posterior vomer mucoperiosteal flap was designed by dissecting the posterior vomer, and then each side of PVMF was sutured with the same side mucosal flap and the levator veli palatini. Result: This method was applied in 55 cases with satisfactory results of extending and elevating soft palate, and achieving velopharyngeal closure.

55例先天性Ⅱ、Ⅲ度腭裂患者犁骨后缘正中纵向剖开，分别形成两犁骨后缘犁骨粘膜瓣，将腭帆提肌止点连同同部位软腭鼻腔侧粘膜一起缝合于犁骨后缘犁骨粘膜瓣顶点上，上提后推软腭，再缝合口腔侧粘膜。

The location and morphology of vomeronasal organ of the Cricetulus barabensis and Microtus mandarin us are similar, but vomeronasal epithelium、womeronasal lumen and vomeronasal blood vessel show significant diffidence in the three species.

结果表明，黑线仓鼠和棕色田鼠犁鼻器在位置和形态上相似，但这三种鼠犁鼻上皮、犁鼻管腔和犁鼻血管均有较明显的差异。

The physiology of the skin machine body for the sake of the environment in the maintenance stability, but eject a body metabolism creation of metabolism thing BE'grease', summer perspire many various skin disease light or good, autumn perspire little metabolism thing metabolism don't go out, various skin disease made, this be the skin machine body of various burning disease.

皮肤机体的生理为了维持内环境稳定，而排出身体代谢产生的代谢物是'油泥'，夏天出汗多各种皮肤病就轻或好了，秋天出汗少代谢物代谢不出去，各种皮肤病就犯了，这就是皮肤机体的各种炎症。

If I had anything tender in me, I shot it dead.

如果我有什么招标的话，我枪死亡。
