单管的

Under the single phase state, verification of coupling between the two codes was performed with horizontal pipe blowdown problem firstly.

在单相范围内，首先利用水平圆管喷放问题验证了程序间耦合的正确性。

The experiment results prove that the boiler coking is largely reduced and the temperature difference of two sides of horizontal gas-pass is very small, when the 330MW boiler operate, the pressure of primary hot air parison is controlled beyond 12.0～12.5KPa, the O2 content of air pheheater is controlled about 3.0%, the door of OFA is opened to 30%, the buffle of the inner secondary air sleeve is adjusted to the minimum, the outer secondary air swirling strength and the baffle of the outer secondary air sleeve is regulated to the maximum and the outlet temperature of pulvervised mill is kept in 70℃.

试验结果表明，330MW运行时，一次热风母管压力控制在12.0～12.5kPa以上、空气预热器实际氧量控制在3.0％左右、燃尽风门开至30％、内二次风量套筒挡板调整在最小、外二次旋流强度和外二次风套筒挡板调整到最大、磨煤机出口温度维持在70℃，此时锅炉结焦大幅度减轻，水平烟道两侧烟温差非常小。优化试验完成后，进行了单烧灵武烟煤对比，结果是：掺烧高灰熔点的银北煤后，炉膛结焦大幅度减轻，锅炉过热器减温水量较小，主蒸汽压力易提高，带负荷能力正常；再热器烟气挡板开度较大、减温水量较小；风机电耗较小。

The main sources of uncertainty of measurement for 10 mL singlet burette certification were analyzed.

分析了10mL单标线刻度吸管进行容量检定时测量不确定度的主要来源，对各不确定度分量进行了分析和量化，得出合成标准不确定度和扩展不确定度结果分别为0.00068mL和0.0015mL。

It is shown that the mechanical properties including Young's modulus, tensile strength, critical strain and stress under buckling can be enhanced with the decreasing of intershell spacing. The shear strength can be enhanced by 2-3 orders of magnitude when the intershell spacing is reduced to 20%, which is also dependent on commensuration. Zigzag-type carbon nanotubes have higher shear strength. The axial stress in tubes when the load transferring from outmost tube to inner tube is observed as well.

研究了单壁纳米管束横截面的六方化失稳现象，给出各种管径的面内压力－应变关系曲线；每条曲线都给出一个明显的拐点而且有很强的非线性；线弹性模量与参考构形有关，也受管直径的影响；分析了管束横截面的晶格不稳定性特征，表明晶格的缺陷能够明显的减小临界值；模拟了在不同应变下纳米管束对静水压的反应，发现不同压力下的截面形态不同，在很高压力下相邻管之间会形成化学键。

Based on the force constant model we calculate the phonon dispersion relations of single wall BC3 nanotubes with different diameters and chiralities.

描述了单壁BC3纳米管结构的表征方式，比较详细地给出了其结构、对称性和晶格动力学分析。

For example, neural tube defects （NTDs--anencephaly, spina bifida, encephalocele, myelomeningocele） usually have multifactorial causes, although they also have many specific known single-gene, chromosomal, and environmental causes.

例如神经管缺陷（NTD，包括无脑，脊柱裂，脑膨出，脊髓脊膜膨出）通常有多基因造成，虽然也有许多已知的单基因，染色体和环境原因。

For bulk carriers, the side shell is one of the weakest parts of the hull. Most of previous bulk carriers are single-hull bulk carriers, according to the casualty statistics of bulk carriers, the accident rate of the side shell of the single-hull bulk carriers is highest among hatch, pipe, deck, side shell and bottom etc.

散货船的舷侧结构是整个船体结构中最薄弱的环节之一，目前绝大多数散货船为单壳结构，根据多年的散货船事故统计显示，在舱口盖、管系、甲板、舷侧外板、船底结构等诸多损伤中，单壳散货船的舷侧外板事故率是最高的。
