犁

But there are no report of the design and research on bionic adhesion decreasing efficiency of the standard disk plow that has a great difference to other soil touched component on working manner and force support status currently.

但对于工作方式和受力状态都与其它触土部件有较大差异的圆盘犁，其仿生减粘效果如何，目前国内外尚无进行过仿生设计与试验研究。

The dispersoid distribution of the second phase could strengthen the surface of the alloy, which decreased the quantity of abrasive particles. The wear volume of the alloy was decreased. The hardness and strength of the alloy were increased after ECAE. The resistance of deformation was improved and the depth and width of furrows were decreased due to the increase of hardness and strength. As a result, the wear-resistance and tribological properties of the alloy were improved after ECAE.

ECAE热挤压处理显著细化了铝青铜合金的微观组织，弥散分布的第二相对合金起到强化作用，减少了剥落磨粒的数量，降低了合金的磨损量；ECAE热挤压处理的铝青铜合金组织细小，强度和硬度高，提高了合金抵抗塑性变形能力，减轻了磨粒对合金表面的犁削作用，提高了合金的摩擦磨损性能。

The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

He had jogged across half a dozen ploughed fields on a quiet grey pony of Sir Michael's, and drawing up breathless and panting at the door of some farm-house, had expressed his intention of following the hounds no further that morning.

他曾经骑着迈克尔爵士的一匹文静的灰色小马，缓步经过五六块犁过的田地，上气不接下气地勒马站在一家农舍门口吁吁喘气，因而那天上午他表示无意再跟着猎狗驰骋了。

That field of corn, would never see a plow.

一片田地上你看不到犁车。

You will also be encouraged to try out various farming tools to furrow the ground and so on.

我们也鼓励你尝试使用不同种类的耕作工具来犁田等等。

Every furrow in the book of Psalms is sown with the seeds of thanksgiving.

诗篇的每一道犁沟都撒下感恩的种子。

Hollow out in the form of a furrow or groove .

以犁沟或开槽的方式来挖掘。

Late in life, Gatling did divert his attention to steam-powered ploughs.

加特林到了晚年，他确实将注意力转移到了蒸汽式的犁。

And with these results, I delve further into the theoretical issues of MSP and the concentration is on a special class of MSP-Doob skeleton processes. Generalized limit distribution, limit distribution of these processes and conditions and the expressions for the existence of invariable measure of such processes are provided. Finally, these new results are then applied to queueing theory, reliability theory and inventory theory. A detailed study of GI/G/1 queuing model, parallel connection system model, water reservoir model and perishable inventory model is discussed. These models have already been investigated to some degree. In particular, as mentioned above, some scholars have already successfully applied the transient behavior theory of MSP to these models and transient distributions of main variables in such models have been obtained. However, the limit behavior has not been addressed. In this thesis, limit behavior of main variables in the above-mentioned models is established.

在这个基础上，对马尔可夫骨架过程的理论进一步进行了探讨，将注意力集中于一类特殊的马尔可夫骨架过程Doob骨架过程，给出了这类过程的广义极限分布、极限分布以及不变测度存在性条件和表达式，并应用这些结论于排队论、可靠性理论和存储论等领域-具体分析了GI/G/1排队论系统模型、并联系统模型、水库储水模型、易腐烂物品库存模型——这些模型都不同程度地被许多学者研究过，特别，如前面提及，已有人成功地应用马尔可夫骨架过程的瞬时性态理论，获得了上述各模型中的主要参量过程的瞬时分布，但是，却并没有探讨它们的极限性态——建立了若干关于上述各模犁的主要参量过程的极限性态的结果。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
