Compared with the pillar subsoiler and the subsoiler with a break shovel, the traction resistance, power consumption and the width of scarification channel were reduced.

针对立柱式深松机在作业过程中存在的缠绕堵塞、牵引阻力大等问题，该研究提出在原深松铲前方加装一个松土铲或圆盘刀两套研究解决方案，研制了机具，并进行了田间对比试验研究。

A new kind of subsoiler with adjustable wines has been developed and thestructure of soil after subsoiling is also studied,it is found that thissubsoiler can loose whole surface of soil with intervally looseing the deepsoil,making a better seed bed for planting narrow row spaceing crops such aswheat.

分析了可调翼深松铲的入土性能，研究了松后土壤结构，试验发现，利用安装位置较高的可调翼深松铲，可以为小麦覆盖地创造"表层全松底层间松"的土壤结构，这种结构有利于行距较小的小麦等密植作物播深均匀，该深松方法与原理具有新意。

The mechanisms of material escped from grate spading plate was analysed,and countrmeasures were proposed.

叙述了铲料板的结构型式及作用，分析了现在使用的链篦机铲料板漏料的原因，并提出了处理方法。

The design level of the spade and the tree transplanter is limited by lack of the quantitative description of spading resistance in the course of spade movement.

铲刀是树木移植机的关键作业部件，目前由于缺乏铲刀下铲过程中下铲阻力的定量描述，使铲刀乃至整机的设计水平受到一定限制。

Of implements for harvesting, beside the spade, prong-hoe and spading- fork, very few are used in the small garden, as most of them need not only long rows to be economically used, but horse- power also.

收获的落实，旁边铲，叉-锄头、铲叉，很少用于小花园由于他们大多需要长期争吵不仅要在经济上使用，但马力也。

Firstly this paper explores the main systerm modeling methods in hydraulic grab;then we focus the analysis on the kinematics and bear of the back shovel dig device, the request of the gig ability, the task efficiency , the endure intension; after that we creat a rational maths model and write a program to ananlysis the data acquired; finally, this paper gets the optimize parameter and scheme, and protracts the grab envelope chart.

论文首先对液压挖掘机主要系统建模方式进行探索，然后重点对反铲挖掘装置运动学及受力进行分析，分析反铲挖掘装置的挖掘能力要求、作业性能要求、作业效率要求、受力状态要求，进行运动学和动力学分析，创建合理的数学模型(设计变量、目标函数的确定)，利用合适的优化方法编写计算机程序，调试通过程序应用，最后对优化结果进行分析整理。

But finally, the people must buries alive her, is actually that boy, shovelled the first shovel earth.

但是最后，人们要将她活埋的时候，却是那个男孩，铲下了第一铲土。

Shovel sand; he shovelled in the backyard all afternoon long.

铲沙子；他整个上午都在后院铲。

Right off the bat, the lander's robotic scoop appeared to hit solid ice just below the surface, and scientists were rewarded with time-lapse images of ice subliming into the thin Martian atmosphere from one of the trenches it dug.

凤凰号在当初刚着陆时，它的机械铲铲似乎就碰到了地表下的固态冰，同时科学家们也满意得看到了，在它挖出的一个沟渠中有冰升华到火星稀薄大气层中的延时图像。

The shovelfuls of loam, black as 'et, brought there by the river when it was as wide as the whole valley, were an essence of soils, pounded champaigns of the past, steeped, refined, and subtilized to extraordinary richness, out of which came all the fertility of the mead, and of the cattle grazing there.

一铲一铲的黑土，像墨玉一样漆黑，是在河流还同山谷一样宽阔时被冲到这儿的，它们是土壤的精华，是过去被打碎的原野经过浸泡、提炼，才变得特别肥沃，从这种土壤里又长出丰茂的牧草，喂养那儿的牛群。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
