螺钉

When tested with vertical load, DHS and low angle external fixator were significantly stronger than the other three groups.

3在抗压力方面，动力髋螺钉最强，与其余各组有显著性差异，其次为低角度倒三角形外固定支架组，优于其余三组。

Results: the pullout strength were increased when the extraversion angle were augmented from 5o to 30o.

结果：在5°～30°的范围内，随着外倾角的增加，椎弓根螺钉的把持力增加，但对椎体的应力也增加。

3 In the mounting or supporting of small, fragile insulating parts, screws or other fastenings should not be tight enough to cause cracking or breaking of these parts with expansion and contraction.

14.3在装配或支撑小而易脆的绝缘件时，螺钉和其它紧固件不要装得太紧以致于这些绝缘件的收缩或扩展而破裂。

Results:According to Stanffer criterion of therapeutic effectiveness, the treatment group of fibular autotransplantation had 6 favorable cases, 1 common case and 1 disappointed case.

结果：34例手术患者按Stauffer疗效标准，自体腓骨移植治疗组，良好6例，尚可1例，差1例；椎弓根螺钉治疗组良好24例，尚可2例，良好率达92.3%。

Twenty four fresh femora were randomly divided into 4 groups with 6 specimens in each group.

按下列分组连续进行测试：A组：1-2-6（1-2-6表示螺钉位置）；B组：1-2-3-6；C组：1-2-3-4-6；D组：

F. Install the gusset plate and gusset box, make them parallel to the lock and match the lock tongue.

F。 安装扣板及扣盒，对齐锁体，应使锁舌与之配合顺畅，拧紧螺钉。

The panel-furniture part joining tensile strength and simulate modulus of rigidity along with their connecter(dowel, eccentric connecter, hangnail fixed connecter, wood screw, wooden peg, adhesion and so on), base material influence factor and so on, which are joining spot and joining way are different but changes.

板式家具部件结合的抗拉强度和模拟抗弯刚度随着其连接件(圆棒榫、偏心连接件、倒刺固定连接件、木螺钉、木钉和胶结合等)、基材的性能、连接部位和连接方式等影响因素的不同而改变。

We have advanced imported equipment such as the panel saw from Germany, the timber we fell with which doesn't have any burst opening; the automatic extruder from Japan, which automatically seals the lines of planks, thus ensuring their quality; the row drill imported from Germany, which guarantees that wooden bolts and linkers instead of screws are used in installing the sideboard; and the hinge joint from Germany, with which we use for perforation, using the advanced German 32 positioning system.

我们有先进的进口设备，德国的开料锯，开出的木料没有爆口；日本进口的自动封边机，对板材进行自动封边，保证了品质；德国进口的排钻，保证了柜体安装使用木销和连接件，而不使用螺钉；德国的铰链机打孔，采用德国先进的32定位系统。
