可牵引的

It has been shown by allalysis that to predict the multi-pass performallce of a driven wheel on sand with Bekker s theory will result in a larger error.

应用本文的方法，可明显改善刚性驱动轮在松散沙土上重复通过时牵引性能的预测精度。

In this case, we tried to use the alveolar bone splitting technique with the Piezosurgery, and the incison line was put in the alveolar ridge as lingually as possible that the integrity of the cortical plate of the alveolar ridge is reserved in the buccal side. Because the resistance to the mesial movement of the posterior teeth is greatly decreased, the possibility of the root resorption or dehiscence is reduced, and the stability after the orthodontic treatment would be improved while the height and width of the alveolar bone increase.

本病例尝试以超音波骨刀，於缺牙区进行齿槽骨劈开手术，其切线尽可能靠近齿槽之舌侧，以使齿槽上的皮质骨板可完整置於颊侧；这样当后牙向前牵引时，才不会因皮质骨板而阻碍前进及牙根被吸收或裂开，同时也能增加齿槽骨之高度与宽度，亦可使矫正后的牙齿更加稳定。

In this case, traction to the legs may be applied to long strips of adhesive strapping fixed to the legs.

在这种情况下，牵引至腿部，可用于长期带胶粘剂的strapping固定双腿。

It is based on a bendable rubber track that guarantees maximum traction as well as freely changeable directions.

它是基於轨道，保证最高可折橡皮牵引以及自由多变的方向。

In order to control the insufficient transition displacement of the long rail components to ensure the high regularity of turnout and its locking reliability, a transition design method for long rail components and double limb elastically bendable turnout frog structure was established using the finite element method, a new roller sliding platform was developed, and the transition traction point layout and stroke design were optimized.

为控制长大轨件转换不足位移，确保道岔的高平顺性和锁闭可靠性，运用有限单元法进行长大轨件及双肢弹性可弯心轨结构的转换设计，研制出新型辊轮滑床台，并优化了转换牵引点布置及其动程设计。

RESULTS: Distraction osteogenesis implants contained intraoral or extraoral distraction device, which could be used for distraction of transport plate.

结果：牵张成骨植入物分为口内牵张器和口外牵张器，可进行转移盘的牵引。

Mandibular widening by means of intraoral distraction osteogenesis is an easy, predictable and controlled method that creates new bone.

下颌骨扩大利用内牵引成骨术是一种简单，可预测和控制的方法，创造了新骨。

In the power supply of the windlass mechanism, carriage trolleying mechanism and slewing mechanism,and install master ZK pneumatic switch,and current is 120A,if the current load more 120A,the power will be automatism cut off.

3.5.2.2 自动空气开关 automatism pneumatic switch 在卷扬机构，小车牵引机构和回转机构的供电线路中，装有总空气开关 ZK，脱扣电流为 120A，若线路负载超过 120A，可自动切断电源。

It has features different from the deformation and failure of an ordi- nary slope. It can be divided into four characteristic zones of deformation.(1) traction collapse,(2) sitdown sink,(3) graben sink and deformation influence zone.

具有与一般斜坡变形破坏所不同的特征，可将其分为四个变形特征区：即牵引式塌落区、坐落式塌陷区、地堑式塌陷区和变形影响区。

The MG700-WD mining machine is a kind of electricity drawing and high-power mining machine, this machine's fuselage is low, installation-power is large, all electric motor are fixed up horizontally, mechanical drive is all the transmission of gear, electric motor、walking case drive wheel package etc, can take from old pool side out, so the transmission is high in efficiency, easy to install and maintain.

以下为资料的部分内容，如需要全部资料请点击获取全文论文编号：JX414 包括设计图，说明书字数：22278。页数：75MG700-WD型采煤机是一种电牵引大功率采煤机，该机机身矮，装机功率大，所有电机横向布置，机械传动都是直齿传动，电机、行走箱驱动轮组件等均可从老塘侧抽出，故传动效率高，容易安装和维护。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
