In conclusion, it is suggested to select gilts from primiparous sows for replacement in order to shorten generation interval and thus to accelerate the genetic improvement in pig selection program.

因此，建议选留初产的女儿猪为种畜，应可缩短世代间距，加速选拔。

The Shi zi mountain rock tunnel which connecting the Punan expressway and the Nanping city in Fujian province were taken as engineering background. Associating plentiful of field test data of vibration velocity with the finite element numerical simulation which based on MIDAS/GTS software, the blasting vibration behavior of the precedence tunnel in the Shi zi mountain rock tunnel was studied. For further, the effects that lining support systems with variation parameters, such as the length, the distance and the length of rockbolts, the spacing of steel braces, the thickness and reinforcement quantity of the secondary lining,,on the blasting vibration behavior of the precedence tunnel were systemlly discussed.

论文以福建浦南高速与南平城区连接线狮子山隧道为工程依托，通过大量的现场振速测试和基于MIDAS/GTS软件进行的三维动力有限元数值模拟，对狮子山隧道先行隧道的爆破振动特性进行了系统研究，并在此基础上进一步探讨了不同衬砌结构参数，如锚杆长度、钢格栅间距、二衬厚度和二衬配筋量等对先行隧道爆破振动特性的影响。

Note that the tube pitch selected for the Reboiler is a deviation from the requirements of the Technical Appendix 3.1.3.9, but is necessary to ensure the optimum design for the units.

注意，为再沸器选定的管间距与技术附件3.1.3.9的要求有偏差，但对于保证该装置的最佳设计是必要的。

According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine l...

按 渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。精细片层区域的比例随着轧制压下率的提高而增大。此外，重度冷轧变形还引起渗碳体严重塑性变形和部分溶解。

The seed layer has an intermolecular spacing of 3.4 -0.3 AA. and it is formed by rodlike supramolecules comprised of disc-shaped molecules of at least one polycyclic organic compound with conjugated p-system.

该晶种层具有3.4±0.3的分子间距，并通过由盘形分子构成的棒状超分子形成，该盘形分子至少为一种具有π共轭体系的多环有机化合物。

Axis: shorten distance between shafts to postpone the longevity of bearing and mechanism sealing; total seal, non-contacting with medium, rustless; need not adjusting when installation; serialization design, high generalization degree.

轴承体及轴承：拆卸方便，有足够的空间用于维修保养；泵体、泵盖、密封室轴承体浑然一体，精美大方。轴：缩短轴间距，以延长轴承和机械密封的使用寿命；完全密封，不与介质接触，不锈蚀；装配时不需调整；系列化设计，通用化程度高。

When the full version has a width of about 1 cm or so deep and sattle marks, may be a question of gear (the most likely reason is that the gear wear or gear spacing has issues).

当满版都有阔度不小约为1公分把握的深不深相间的条痕的时间，不定是齿轮的题目了（最有不定的来因不离是齿轮的磨损或是齿轮间距有题目而导致的）。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
