The statistical result of the phase difference presents the roughly linear dependence on the nanowire diameter.

我们也统计了不同直径的奈米线并发现并不完全符合预期的尺寸效应，这是由於经由激发光萤光机制测量不同直径的奈米线可以发现奈米线内部的缺陷和奈米线的直径成反比，由於氧空缺的增加使得奈米线的铁磁性变强，因此奈米线的磁力并不会和直径的两次方成正比。

The effects of linear velocity at cup's edge and temperature of slag on particle diameter and mass fraction were investigated.

研究结果表明，随着转杯边缘线速度的提高，渣粒平均直径逐渐减小，渣粒向远离转杯的方向分布；当线速度超过6 m/s时，渣粒平均直径的变化随线速度的提高趋于平缓；当熔渣温度在1400 ℃～1500 ℃范围内时，熔渣温度对渣粒平均直径和质量分布没有影响。

The aortic diameter change rates were (-0.2±1.4) mm/year and (-0.18±0.98) mm/year in aortic diameter0 mm group and≥40 mm group, respectively. There was no significant difference between the two groups. The ascending aortic diameter change rates were (0.8±1.6) mm/year in BAV group, and (-0.3±1.5) mm/year in TAV group. The ascending aortic diameter of patients in BAV group enlarged continuously following AVR.

在升主动脉直径0mm组和≥40mm组中，升主动脉直径的变化率分别为(-0.2±1.4)mm/年和(-0.18±0.98)mm/年，两组之间无显著性差异；二叶主动脉瓣组和三叶主动脉瓣组升主动脉直径的变化率分别为(0.8±1.6)mm/年和(-0.3±1.5)mm/年，二叶主动脉瓣组病人的升主动脉直径在主动脉瓣置换术后仍继续扩大。

Moreover, the cutting tip can have a portion of maximum diameter which is of greater diameter than the inner diameter of the sleeve so that the portion of maximum diameter overlies the sleeve radially.

而且，切削尖端(11)可以具有最大直径的部分，所述部分具有比套筒(20)的内径更大的直径，从而使得所述最大直径部分沿着径向覆盖于套筒(20)之上。

The experiment of the auxiliary heated arc plasma generator shows that thekey arc root has contraction under the condition of having magnetic field when thekey arc root is at the edge of the cathode surface.

在辅助加热电弧等离子体发生器的实验中看到：在有外磁场的情况下，主弧弧根在阴极边缘时，弧根有收缩的迹象，而当主弧弧根在阴极中心附近时，观察不到明显的弧根收缩迹象，并拍摄到有双弧柱的图片；当关掉磁场和弧电流〓时，主弧在阴极和阳极之间稳定的燃烧，主弧弧根稳定在阴极中心附近的一点上，而且弧根没有收缩的迹象，主弧弧根亮区的直径约为6.8毫米，与弧柱段的亮区直径相差无几；因而从实验结果分析可以看出，阴极表面温度的升高，能使主弧弧根直径增大：另一方面，由于主弧弧根直径的增大(即也意味着主弧弧根截面积的增大)，因而使电弧通过主弧弧根传入阴极表面的有效比热流降低，从而减少了阴极烧损。

The tree diameter at breast height and crown length can be used to predict the size and location of mean knot diameter in a whorl.A linear mixed model expressed as function of tree and knot variables such as HK、RKD、KD and DBH was used to predict sound knot length,and a log-linear mixed model using RKD and DBH as variables was used to describe loose knot length.4.A knot has four development phases:from the birth of a branch to its growth cessation,from growth cessation to death,form death to occlusion and form birth to occlusion.The numbers of annual rings in four periods,as well as the stem width of respective zones were used as dependent variables predicted by models expressed as function of tree variables and knot attributes.5.Using the data of diameter out side bark of 15 relative heights along the step,the best taper equation for Larix olgensis was established.

节子平均直径可以用以胸径，冠幅和节子高度为参数的舒马克生长方程来预测，用树木胸径和冠长可对每轮节子平均直径的最大值及位置进行预测；健全节长度可用以节子着生高度、相对直径、节子直径以及树木胸径为参数的线性混合模型来预测，疏松节长度采用节子相对直径和胸径为自变量的可转化为线性模型的自然对数模型来预测；4、节子有四个生长发育时期：从枝条形成到生长停止BC从生长停止到死亡(CD从死亡到包藏DO从形成到包藏
