2Similar to other shrimps, artificial pond culture Penaeus monodon also had difference in growth between female and male. At early culture period, the difference between them was not distinct, but the female would grow more quickly than male after the fifty-ninth day. The body weight growth turning point of the male appeared at the 144.5 days, and at the 195. 3 days for the female.(3) By using Von Bertallanffy growth equation, the growth equations of Penaeus monodon were abtained.

养殖前期，雌、雄虾的体长、体重生长差异不明显，雄虾略高于雌虾，在59.6d后，雌虾体长生长速度高于雄虾；雄虾体重的生长拐点出现在144.5d左右，雌虾体重的生长拐点出现在195.3d左右；(3)采用von Bertallanffy生长方程，拟合出池塘养殖斑节对虾体长、体重生长方程为：。

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。

It was a manuscript containing 53 stories, some written out in detail, others sketched in brief outline form. In December 1810 they submitted this collection to Clemens Brentano and Achim von Arnim for inclusion in a planned third volume to their successful collection of folk poetry entitled Des Knaben Wunderhorn (The Boy's Magic Horn, 3 volumes, 1806, 1808, 1808), which was to be dedicated to folktales.

这是一份包含了53个故事的手抄稿，有些故事描写细致，有些只是有个故事大纲。1810年12月格林兄弟把它寄给了lemens Brentano 和 Achim von Arnim，希望把它包含在这两位作者计划出版的《Des Knaben Wunderhorn (The Boy's Magic Horn， 3 volumes， 1806， 1808， 1808)》第三卷中。

In order to deeply reveal the smoothing mechanism of roller burnishing and to overcome the difficulty in the selection of the burnishing cross feed dependent mainly upon experiences and hand feel, the roller burnishing process is taken as an issue of plane-strain mechanics and the micro-plastic deformation area is determined on the basis of the Von-Mises yield criterion and by using the Boussinesq-Flamant solution. Then, the contact pressure distribution is obtained based on the Hertz contact theory, and the stress distributions in the burnishing tool and the workpiece are respectively revealed.

为深入了解滚柱滚压表面光整机理，解决目前滚压量选择完全凭经验和手感的不足，将滚柱滚压加工过程视为平面应变力学情形，利用Boussinesq-Flamant问题的求解并根据Von-Mises屈服准则得出了滚压局部发生微塑性变形的区域，根据Hertz接触理论得出了滚压接触压力分布及滚压过程中工件和工具的应力分布。

Among these are a heart-stopping rendition of the previously unreleased 'Gitardjamm', filmed inside a derelict herring oil tank in the far West Fjords; a windblown, one-mic recording of 'Vaka', shot at a dam protest camp subsequently drowned by rising water; and first time acoustic versions of such rare live beauties as 'Staralfur', 'Agaetis Byrjun' and 'Von'.

其中的一些就是尚未发行的《Gitardjamm》中压心的演奏，在远西峡的一个遗弃了的窄油槽*中拍摄；一段风吹，《Vaka》中用单话筒录下的，在一水坝阻流营地拍摄；以及像《Staralfur》《ág？tis Byrjun》(1999.6)和《Von》(冰岛1997，英国2004.9，美国2004.10，Sigur Rós首张专辑)这样极罕见的难忘美好的首个非电版*。

The growth of Schizopygopsis stoliczkai stoliczkai could be fitted with von Bertalanffy equation. There were inflexions in growth rate and growth acceleration of body weight, the reflection point was t=10.18 years. Growth rate and growth acceleration of body length would change as time.
