1)  elongational flow
伸展型流动
2)  extensional activities
伸展活动
1.
The extensional activities along the Tan Lu fault zone occurred in the period between Late Cretaceous and Palaeogene,and the extensional normal faults were formed along the preexisting strike slip faults.
郯庐断裂带于晚白垩世 -老第三纪 (K2 -E)时期卷入了广泛的伸展活动 ,其伸展结果是沿着早期先存的走滑断裂产生了伸展正断层 ,构成了合肥盆地的东缘断陷边界。
3)  extensional movement
伸展运动
1.
The investigation indicates that the complex structural patterns within the Liaohe intracontinental rift basin were dominated by the extensional movement and simultaneously deformed by the late down tilting movement just in Mesozoic era.
裂谷盆地的形成、演化是在伸展活动发生复杂而有规律的运动中进行的,表现为水平伸展运动、垂直升降运动、掀斜或翘倾运动等,这是裂谷盆地的主要特征。
2.
Based on the analysis of tectonic deformation,extensional unconformity,sedimentary facies and paleogeographical rebuilding of southern Tibet,it is recognized that the extensional movement consists of active extension of Hercynian,Indo Chinese and Early Yanshan epochs,and passive extension of the Himalayan epoch.
藏南特提斯域内伸展运动和伸展作用非常普遍 ,根据构造变形分析和伸展不整合、沉积岩相、古地理再造及岩相对比方法 ,对藏南海西期以来的伸展构造进行了较为系统的厘定 ,确定了海西期、印支期、早燕山期的主动伸展运动和晚燕山期和喜山期的被动伸展作用 ,并对这些运动特征进行了探
4)  passive spread
被动伸展
1.
the passive spread and resistive training is helpful to the active prevention of sports injury.
被动伸展性抗阻功能训练对如何主动预防运动创伤这一问题有较大帮助。
5)  stretching vibration
伸展振动
6)  extended cone and plate flow
扩展(型)锥板流动
补充资料:伸展链长
分子式:
CAS号:

性质:在充分伸展状态下的高分子链的长度。常用R2表示。R2为高分子链的均方末端距,是表征高分子尺寸的一个重要物理量。伸展链主要有锯齿型结构和螺旋型结构两种。对应的伸展链长分别为R2链齿=[Nb·sin(a/2)]2(式中b为键长,a为相邻两键夹角,N为键数)和R2螺旋=K2N2b2(式中K为取向参数的平均值)。
