Tholeiite has a zircon SHRIMP U-Pb age of 352 Ma, suggesting that the formation of the ophiolites may have continued till the Late Devonian-Early Carboniferous.

拉斑玄武岩 SHRIMP 锆石年龄352 Ma ，说明蛇绿岩的形成可持续到晚泥盆世—早石炭世。

The innovations of this paper as follows:(1)The topological relation model between complex spatial objects is brought forward, which represented by some composite basic 9I matrix and results in general signification.(2)Time and space integrated topological model is suggested to reason about spatio-temporal change types;(3)Sweep-line algorithm is improved, and a new little circles of polyline nodes overlapped with region method is proposed. As result, it's efficient to calculate line-line, line-region and region-region topological relations.

本文的创新之处在于提出了一种能够描述复杂对象的数学表达模型，将复杂对象间的复合拓扑关系表示成基本拓扑关系的组合，具有一定的普适意义；研究了时空拓扑关系的内涵和表达方法，说明利用时空拓扑关系可隐性地实现时空变化语义的查询；对平面扫描线法进行了改进，提出了一种新的节点微小圆求交的算法，可有效地解决线面、线线、面面拓扑关系的计算问题。

Cellular structure is simple and has intermediate neurons, which can survive a longer period in vitro. Amphibial sympathetic ganglions show various postsynaptic potential including fast excitatory postsynaptic potential. Slow inhibitory postsynaptic potential.Slow exeitatory postsyn...

两栖动物交感神经节表现出多种突触后电位，包括快兴奋性突触后电位，慢抑制性突触后电位，慢兴奋性突触后电位，晚期慢兴奋性突触后电位，同时还表现多种突触塑性，说明该神经节具有信息存储功能，因此，两栖动物交感神经节可作为研究学习与记忆的模型系统。

Even so, condoms made of animal intestine — known as ＂French letters＂ in England and la capote anglaise in France — remained popular for centuries, though always expensive and never easy to obtain, meaning the device was often re-used.

尽管如此，使用动物肠制成的避孕套，在英国称作＂French letters＂，在法国叫做la capote anglaise，虽然价格昂贵，且不易获取，但是仍然畅销了数个世纪，说明该避孕用具可重复使用。
