摆臂

A switching control scheme is presented for an underactuated Furuta pendulum system, which consists of an actuated arm and an unactuated pendulum.

针对由一个驱动臂和一个未驱动摆杆组成的欠驱动Furuta摆系统，设计了实现其稳定的切换控制系统。

The anticipatory model of special performance and special sensitive indexes is set up for Chinese elite men pole vaulter: y=-1.363+1.191 +1.252(the height of athlete,s single arm-raising).

它们是：单臂举高、技术指标、60m跑、跳远、吊环摆上成支撑、杠铃卧推、垫上后空翻和垫上后滚翻展体成倒立。

Secondly, some are weaker in the cylinder block as middle part of the top wall of combustion chamber, the two clipping arm, the side walls for the left and right of pre-compress room etc., and need strengthening. While, there is some sealing questions for cambered surface of both ends of the centre swing.

其次，在结构上发现缸体左右两个卡臂、预压缩室左右两个侧壁及燃烧室上壁中间部分比较薄弱，需要加强；对于中心摆则是两端弧面的密封有些问题。

Linkages scissored from the twirling pendulums slide up a sleeve on the pole, levering a valve which controls the speed of rotation by adjusting the steam.

从旋转的摆可以通过那根柱子上所伸出的辅臂上滑动，而当它滑动时，就会扳动一个阀门，一个能够通过对蒸汽进行调整从而控制循环速的阀门。

而且，这个系统转得越快，从旋转的摆可以通过那根柱子上所伸出的辅臂上滑动，而当它滑动时，就会扳动一个阀门，一个能够通过对蒸汽进行调整从而控制循环速的阀门。

The evaluation model of special performance and special ability indexes are set up for Chinese elite men pole vaulter: y=-1.251+0.01921(60m race)－0.0104+0.001166+1.537(the height of athlete,s single arm-raising)+1.158+2.304×10-5－0.00278+3.83×10-4.

在专项能力结构中，8个指标的地位是：技术指标＞单臂举高＞垫上后滚翻展体成倒立＞60m跑＞垫上后空翻＞杠铃卧推＞跳远＞吊环摆上成支撑。

An anti-rotation reciprocating drive apparatus for a reciprocating saw utilizes a wobble plate assembly that includes a drive shaft and an elongated arm with an interface structure for engaging a spindle.

一种利用摆板组件的往复锯的防旋转往复驱动装置，摆板组件包括驱动轴和带有为连接心轴的接触面结构的细长臂。

Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.

为大幅度提高其承载能力、传动效率和可靠性诸指标，我们创新研究出来的多种结构双曲柄环板式针摆行星传动，其特点是不仅保留着原摆线针轮行星减速器同时啮合齿数多，总法向力与总圆周力间夹角小，摆线轮与针轮齿均为硬齿面等本质上的优点；而且又具有环板式传动省去输出机构且输出轴刚性好，转臂轴承移至行星轮外，从而传递的转矩可以成倍提高的优点。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
