| 1. | When ignoring the influence of deformation , the constitutive relation can be reduced to that of jaumann derivative
当忽略变形率的影响时，欧拉表述的大变形固结本构方程可退化为通常的jaumann率形式。 |
| 2. | The second point is about the conflict between the supposition that we need to grow continually and that we cannot grow unless we degrade our environment
有人认为，我们需要保持经济的增长，但经济的增长是以环境的退化为代价的。 |
| 3. | It is easily seen that problem ( 1 . 0 ) formally degenerates from a fourth order plate model toward a second order membrane problem when e decreases from 1 to zero
0 )从一个四阶板模型逐渐退化为一个二阶弹性膜问题，因此如果某种有限元方法对( 1 |
| 4. | In the second chapter we discuss the mass - defect in the schwarzshild field and r - n field , and if a = 0 the latter will reduce to the case in the former
第二章详细讨论了史瓦西场中及r - n场中的质量亏损效应，且当= 0时，后者就会退化为前者的情况。 |
| 5. | One of the characters of primary osteoporosis is bone fragility due to low bone mass and regression of the internal bone structure , with alterations of its microarchitecture
摘要原发性骨质疏松症是以骨量减少、骨质微观结构退化为特征的一种全身性疾病。 |
| 6. | Thus many new periodic solutions are obtained and the periodic solutions will degenerate into solitary solutions on the limit condition , which shows this method is more powerful
而且这些周期解在极限条件下可以退化为孤立波解，由此表明上述两种展开法是一种高效实用的方法。 |
| 7. | Osteoporosis is a serious healthy disease , which is characterized by low bone mineral density ( bmd ) and deterioration of skeletal microarchitecture , leading to increased risk of fragility fracture
骨质疏松症是严重影响人类健康的疾病之一，它是以骨量减少，骨的微观结构退化为特征，致使骨的脆性增加，并易于发生骨折的全身性骨骼疾病。 |
| 8. | Regularly riled criterion and constitutive model to rock mass are described in this paper . sometimes four - parameter yield criterion which may degenerate to other regularly yield criterions in some certain conditions are described , too
文中综述了岩体材料常用的屈服准则和本构模型，同时论述了四参数屈服准则在一定条件下可退化为其它几类常用的屈服准则。 |
| 9. | Steel bar and reinforced concrete , nine to five , numerous and complicated day after day , when you and me degenerate into biology that are good at disremembering , especially for come and go in one day as well as our dribs and drabs feeling when we wander around the times river
钢筋水泥、朝九晚五，纷繁复杂的一天天，当你我退化为“善于忘却”的生物，善于忘却一朝一暮的过往，以及你我在时光的河流里游荡时，点点滴滴的心情。 |
| 10. | Another algorithm is based on pixels : sample many points along the curve , round them to the nearest integer and set each pixel the computed point falls in . although this algorithm uses integer arithmetic , it provides the smooth curve possible at the expense of computation time as many points have to be computed to ensure that no gaps are created along the curve . furthermore these two algorithms we mentioned above is appropriate for low degree parametric curves , for high degree parametric curves , we usually approach them by using low degree rational parametric curves , the generating curve ' s fairness property is not very good
我们知道当节点矢量的两端节点均为k重节点且无内节点时， b样条基函数退化为bemstein多项式，因此该生成算法还可推广到b能ier曲线中，具有广泛的应用价值、同样地，在cad和cagd中，有理b样条曲线，特别是非均匀有理b样条曲线( nurbs )已经成为曲线曲面设计中最广为流行的技术，然而对这些曲线目前也尚无很好的曲线生成算法，因此有理b样条曲线的生成算法无疑有着更重要的意义 |
