包围

While the War in Italy was at a Standstill, Marcellus lead his legions to Syracuse an put it under siege.

当时意大利的战争陷入僵局，马塞卢斯率领他的军团包围了叙拉古。

When the algorithm is applied to the Prochlorococcus marinus MED4, our results confirmed earlier reports that tRNA serves as integration hotspot for alien genes and many genomic islands are flanked by direct repeat sequences.

当该方法被运用于PMED4时，我们的结果证实了早期曾提出过的一个观点：tRNA是外源基因的整合热点，许多基因组岛被正向重复序列所包围。

Almost as soon as I graduated from high school in the late 70's, I moved to Poughkeepsie, NY for 4 years at Marist College (midway between Albany, NY and New York City). I experienced what it was like to be homesick my first year but after that, I relished every moment away from home.

在70年代后期，我几乎一高中毕业就搬到了Poughkeepsie，在纽约的Marist学院度过了4年的时光（在被Albany，纽约和纽约城包围的地方）那是我思家的第一年，从此以后，我享受着离开家的每分每秒。

Our neighbours were mostly well to do farmers from villages surrounding the market town.

我们的邻居大多是好做，农民从乡村包围城市的市场。

Marmot said that I must strive to make money, to the ground to build a beautiful house, surrounded every day by this kind of thing.

土拨鼠就说，我一定要努力挣钱，到地上来盖一所漂亮的房子，天天被这种东西包围。

"An external layer of compact bone surrounds a central area of spongy bone , except at the marrow cavity."

骨的外层为质密的骨皮质，包围着海绵状骨松质中心区。

骨的外层为质密的骨皮质，包围着海绵状骨松质中心区。

My childhood is data in the mathematical formula and chart surrounded spent.

我的童年是在数学数据、公式以及图表的包围下度过的。

Based on the elastic theory of large deflection and by taking into account the variation of the axial force and its effects on bending deformation of the drillstring in vertical section,the vibration of the drillstring induced by fluctuating weight-on-bit is described by a parametrically excited system.A Mathieu equation describing the system is established by Galerkin Method.By extending the solution into a Fourier series,the curves of dynamic bifurcation values and the dynamically unstable regions surrounded by the curves are presented.

基于弹性大变形理论，考虑到轴力沿钻柱轴线的变化及其对钻柱弯曲变形的影响等因素，将受自重作用的铅垂井段钻柱在波动钻压激励下的振动转化为一个参数激励系统，用Galerkin方法首次得到了描述此系统的Mathieu方程，并通过将方程的解展成富里叶级数的方法，得到了该振动系统的动力分岔值曲线及其所包围的动力不稳定区。

Surrounded, surrounded, in measureless oceans of space
