Roundness tolerance of pitch diameter Roundness tolerance for a minimum of 345o circumferential arc of the pitch diameter shall not exceed .002 inch (0.051 mm) total, or one half the pitch diameter tolerance if the pitch diameter tolerance is less than .004 inch (0.102 mm); roundness tolerance of the remaining 15o maximum circumferential arc shall not exceed .004 inch (0.102) total, provided such tolerance does not result in excrescence on the thread flank.

圆度公差沥青直径圆容忍最低限度的345o圆周弧音高直径不得超过0.002英寸（ 0.051毫米）总，或一的一半，足球场直径公差，如果沥青直径公差小于0.004英寸（ 0.102毫米）；圆的耐受性，其余15o最大周弧不得超过0.004英寸（ 0.102 ），共计提供这样的宽容不会导致在excrescence对线程的侧翼。

The larger the handrim, the greater the moment about the wheel axle M could attain. The tangential force F applied to the handrim was similar among three handrim diameters. However, the radial component of force applied to the handrim increased as handrim diameter decreased.

结果发现，轮圈直径越大，最大前进力矩越大；不同轮圈直径，施加在轮圈的切线分力相似；但轮圈直径越小，施加在轮圈的轴向分力却越大；而轮圈直径越大，有效分力比率也越大。

Reynolds number of impingement, inclined jet angle, the ratio of the jet distance to the diameter of the jet hole and the relative curvature (the ratio of the diameter of jet hole to the diameter of concave surface) were changed to study the rules of flow structures varying with these parameters. At the same time, the developing and disappearing phenomena of the induced vortex were analyzed.

通过改变冲击雷诺数、冲击角度、相对冲击间距（冲击间距和冲击孔直径之比）以及相对曲率（冲击孔直径同凹面靶板直径之比）等参数，分析了受限空间中，斜向冲击曲率表面后产生的涡系结构及其发展和变化规律。

Subgradient projection method with variable diameter for optimization;2. The variable diameter deephole blasting was adopted to solve problems of open-pit high bench mining.

采用变直径深孔爆破工艺可较好地解决露天矿高台阶开采的爆破根底问题，对等直径和变直径 2种深孔形式爆破后岩体移动速度情况采用高速摄影手段进行了分析和研究，为在高台阶开采的矿山推广变直径深孔爆破提供一些有益的参考依据。

It has been found that the cation exchange on diffusivity may play the role in different ways for different zeolites. When the diameter of the diffusant molecule is much smaller than the pore or cage size of the zeolite, the influence of exchanged cations is mainly by way of altering the electric field intensity (or the density of electric charge), the large the Z/r of the exchanged cations, the smaller the diffusivity; while the diameter of the molecule is apporsi- mately equal to the pore or channel size of the zeolite, the exchanged cations may affect the diffusivity by means of blocking up or narrowing the channels of the zeolite.

金属阳离子交换对扩散的影响表现为：当扩散分子的直径比分子筛孔道直径小得多时，交换阳离子以改变分子筛内部电场强度或电荷密度的方式影响扩散速度，阳离子的Z/r越大，扩散系数越小；当扩散分子直径与分子筛孔道直径相近时，交换阳离子则因堵塞或窄化孔道而改变分子的扩散速度。

Results:(1) The two nerves were found anatomically related at 5～10 mm and 26～30 mm respectively following hypoglossal nerve entering the muscle.(2)The diameter of the two nerves were observed to match well with each other or with the main branches at 10 mm following the branching of hypoglossal nerve.(3) At 6～10 mm prior to the branching of hypoglossal nerve there was a branch going to the lingual muscles and plexiform of lingual nerve.

结果：(1)舌下神经与舌神经之间有二个恒定的联系部位，即舌下神经分支进入舌肌后最初5～10 mm处和26～30mm处；(2)舌下神经与舌神经最佳吻接部位，我们认为应在舌下神经主干分叉后10 mm左右；神经直径测量也发现神经直径与舌神经主干和分支直径较为匹配，且此区有利解剖，便于神经吻合；(3)舌下神经分叉之前，在神经干上方距分叉约6～10 mm处有一较固定分支，参与分布舌肌并与舌神经呈丛状结构。
