In this sequence th golfer is shown waggling, returning to address, and then swinging to the top of his backswing.

在这个次序中，球员摇杆，转向瞄球，然后摆动到上杆顶部，每幅图都强调了身体部位在上杆的每个特定阶段的功能。

Whippy A shaft more flexible than normal.

软球杆：比常规杆更柔软的杆身。

Research shows that temperature, slenderness ratio, section forms of rods, and covering layer thickness to members under fire conditions have a sizable effect on critical load and length of rods, but the effect of rod dead load may be overlooked.

研究表明，温度、长细比、杆件截面形式、保护层厚度对杆件稳定临界荷载和临界长度影响较大，构件自重的影响可忽略，在此基础上给出了不同约束条件下杆件的计算参数。

Aiming at the limitations of the way to increase the static stiffness of the boring bar ,this paper adopts a novel thinking way that aggrandizes the dynamic stiffness of the boring bar to design a bar with a vibration absorption system in the boring bar .

针对一般方法增加深孔加工镗刀刀杆静刚度的局限性，采用了一种新颖的增加刀杆动刚度的思维方法，对内藏式减振刀杆进行了设计。

Zhou, who shot a 2-over 74 on Thursday, was 10 strokes worse on Friday, his chances of making the weekend cut all but erased after his opening eight holes resulted in five bogeys and two double bogeys.

周在星期四打出了74杆高于标准杆两杆的成绩，星期五的成绩比星期四差了十杆，他晋级的机会在打完前八个洞之后彻底丧失了，前八洞他打出了5个柏忌和2个双柏忌。

They are the strengthening-toughening of 40SiMnCrNiMoA by the critical normalizing, the fine macrostructure and property matching between the all drill rod parts, the low tendency of decarburizing and delete the weak inner hole surface owe to the drill-hole and hot-rolled with core process of rolling steel.

本文研究表明，40SiMnCrNiMoA钢亚温正火强韧化特性、亚温正火使钎杆整体性能良好地匹配、较小的脱碳倾向和钻孔法消除钎杆内孔粗糙和脱碳表面是钻孔法并整体780℃亚温正火+钎柄淬火和低温回火的H22-40SiMnCrNiMoA锥体连接小钎杆延寿的主要原因。

Others, parts on Kelly bar shouldn't be changed or demounted at random; welding shouldn't be done on the part which did not weld formerly; maintenance should be guided by manufacturer, it is prohibited to weld the key side in principle, welding should be done on three keys at one time, indexing is ensured by grinding after welding, internal keys should be grinded of its full-length to ensure indexing.

其它，钻杆上的制件不要随意拆换或卸掉；不要在原来不焊接的部位自作主张焊接；维修钻杆要有钻杆生产厂家指导，原则上不允许对键侧进行焊补，焊补要三键同时进行，焊补后修磨保证分度，内键要通长焊补修磨，保证分度。

Refer to the impacting-echo technology, we impacted the apex of the steel bar and incepted the reflecting stress \\ave through the resonator that fixed on the apex of the steel bar, and the value of the consolidating wave speed was calculated based on the timeof stress wave transmitted and the length of the steel bar, so, identifying the reflecting signal is the key of the consolidating wave speed method.

借鉴于冲击回波技术，固结波速的测定方法是在钢筋测杆的出露端施加瞬态冲击载荷，由安设在测杆顶端的传感器接收反射应力波信号，根据应力波的走时和测杆的长度折算固结波速的大小，因此反射信号的识别是固结波速法检测混凝土强度的技术关键。

In the transmission mechanism of optional drive ratio worm crank pin,the circular pitch of annulus worm changes from the function of optional drive ratio.When the annulus worm tums equably,the roll-pin crank brings shift tuming through joggling,and it can applly to dumping and turning mechanism of ladle.

变传动比蜗杆曲柄销式传动机构，其环面蜗杆的齿距是依变传动比的函数关系变化的，当环面蜗杆匀速转动时，通过啮合使滚销式曲柄产生预期的变速转动，可应用于铸造生产的铁水浇包的倾转机构。

Cleveland Series HiBore is the main product of this year, the beginning of the year by Vijay Singh on the 1st endorsement wood, and its most salient feature is the oblique head of the geometric design, this has only recently listed under the mixed no exception.

HiBore系列是Cleveland今年主打的产品，年初就由Vijay Singh代言一号木杆，其最大的特色就是斜切式的几何杆头设计，这款最近才上市的混血杆也没有例外。
