Not only does the FourTrax Rincon GPScape boast features such as a 675cc liquid-cooled single-cylinder four-stroke engine, a fully independent rear suspension and TraxLok, it also comes with Honda's patented, industry-exclusive, GPScape navigation system.

不仅不fourtrax rincon gpscape吹嘘功能，如作为一个675cc液体冷却单汽缸4冲程发动机，一个完全独立的后悬架和traxlok ，它也与本田公司的专利，工业专用， gpscape的导航系统。

The paper attempts to design and development a new type of hydraulic pump. It is the design of combining the advantages of sucker rod pump and rodless botttom hole pump, without pumping rod,and depends on the hydraulic system on the ground providing the impetus. The paper uses the pump Swabbing Principle to design the main parts of the pump structure and size, analyses and calculates the up down stroke of the piston and the switching process of pump valve, uses the finite element method to analyse the main force summing element and check intensity, and designs a ground hydraulic control system to match it. Considering the need of deep mining, salvage equipment is designed. The design shows that there is feasible and reliable to realize the exploitation underground using the new hydraulic pump. The design idea in this paper enlightens the rodless botttom hole pump production in the future and other similar issues.

本文尝试一种新型液力泵的设计和开发，它的设计思想是结合有杆泵和无杆泵各自的优点，取消抽油杆，依靠地面液压系统提供动力，本文从抽油泵抽汲原理出发，设计了抽油泵主要部件的结构和尺寸，对上下冲程柱塞的运动规律和泵阀启闭过程进行分析和计算，使用有限元法对主要零件进行了受力分析和强度校核，并设计与之配套使用的地面液压控制系统，考虑深井开采的需要，一并设计了打捞装置，为理论上实现了这种新型液力抽油泵井下开采的可行性和可靠性做了一些基础的工作，本文的设计思路对今后无杆泵采油等类似问题的研究做了有益的尝试。

Oil of housing card Rotella T5W/40 is a kind of complete synthesis engine of heavy load derv is oily, function satisfies engine of derv of all four-stroke loop to produce business demand.

梗概： 壳牌Rotella T5W/40油是一种全合成重负荷柴油发动机油，性能满足所有四冲程循环柴油发动机生产商要求。

The termin flightmentioned in the preceding paragraph means the period beginning from the moment when power is applied by a civil aircraft for the purpose of actual takeoff until the moment when the landing run ends.

前款所称飞行中，是指自民用航空器为实际起飞而使用动力时起至着陆冲程终了时止

I never gave it much thought as to why, in my experience, lower Xmax woofers sound better.

我从来没有对此思索很多，根据我的经验，冲程较短的低音喇叭声音较好。

On the other hand, excessively large clearance can result in piston slap as the piston starts down on the power strokes.

另一方面，间隙过大则会在做功冲程开始时引起活塞敲缸。

Omnibuses conglomerate in conflict—for ever desiring—(the clock asseverates with twelve distinct strokes that it is midday; light sheds gold scales; children swarm)—for ever desiring truth.

Omnibuses conglomerate conflict 为曾经渴望(the 的时钟asseverates 以十二个分明冲程，这是午间；光流洒金标度；孩子swarm)为曾经渴望的真相。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
