极限

These X Games Fiestas will be somewhat tamer, but still fully capable race cars out to win the X Games Pro Rally title.

这些极限运动节日将会有所温和，但仍然完全有能力赛车赢得了极限运动职业拉力赛冠军。

The so-called plasticity seal, the seal is the sealing surface pressure is equal Sealing than the soft material yield limit, so that Pressure sealing globe valve joint surface in close contact, use the plastic deformation of soft materials, blockage hardware uneven surface, giving rise to approximate the ideal plane, and produce equivalent soft material yield limit of the reaction and remain sealed.

所谓塑性法密封，就是密封面的密封比压等于密封副软材料的屈服极限，使结合面紧密接触，利用软材料的塑变而堵塞硬件表面的不平处，形成近似理想平面，并产生等于软材料屈服极限的反力而保持密封。

There are two causes leading fractures of the endodontic instruments. Firstly as the value of the toque inc1ases beyond the limited toque, the instrument will twist with no increase in toque and will fracture soon. The value of limited toque is proportional to 3 squares of the file radius.

根管器械断裂的原因主要有2个：一是扭转超过极限扭距，器械顺着扭转的方向发生塑性扭转直至断裂，圆杆的极限扭距与其半径的3次方成正比；二是器械在循环载荷下发生疲劳损伤，最后突然断裂。

Of the first study on the impact of the ultimate strength, the rate is Ligan initial bending pipe wall thickness and the impact on the ultimate strength coefficient.

文献[6]研究分析了第一个因素对极限承载力的影响，给出立杆初始弯曲率和钢管壁厚对极限承载力的影响系数。

Established the crank fillet to rolling strengthened the equivalent column mechanics model, inferred has calculated the crank and rollings the cutting tool design parameter, rollings the cutting tool disposition situation as well as the material performance parameter limit rollings the load the formula, proposed the crank rollinged strengthened the increase principle and the limit rollings the load the definite method.

建立了曲轴圆角滚压强化的当量圆柱力学模型，推导了曲轴和滚压刀具结构参数、滚压刀具配置情况以及材料性能参数的极限滚压载荷的计算公式，提出了曲轴滚压强化的加载原则和极限滚压载荷的确定方法。

Large ordinals can also be defined above the Church-Kleene ordinal, which are of interest in various parts of logic.

因此对于极限序数，存在着带有极限α的一个δ-标定的严格递增序列。

The permanent wilting point is reached when the plant has wilted to a point where it will not recover, even if more water is added, because the cells have plasmolyzed.

当植物的萎蔫达到一定程度就不可以再复原，这一极限被称为永久萎蔫点。超过此极限，补充再多水分也不能被吸收，因为已经胞质浓缩已经到达质壁分离的程度。

It has been certified that the maximum tensile and elongation of wheat straw without stem node is more than that of wheat straw with one stem node.

通过拉伸实验，测试了无茎节和1茎节麦秸秆在天然、浸海水、浸胶及浸胶后再浸海水4种工况下的极限拉力和极限延伸率。

The way to improving throwing power: the suitably high current density, polarization curve is the fine way to find suitably high current density.

解决镀层延展性的方法：尽量高的的电流密度，不高于极限电流密度。寻找尽量高的电流密度方法：测量极化曲线，从中找出极限电流密度。

The way to improving throwing power: the suitably low current density, about 1/3 limited current density; high ratio of sulfuric acid to sulfate copper.

解决深镀能力的方法：适当低的电流密度，即1/3极限电流密度大小；高酸低铜配比；寻找适当低电流密度和极限电流密度的方法：极化曲线方法。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
