类似球体的

In my former post with the name Trip to London 2nd week, I invited you to guess the structure of a ball-shaped video installation.

在名为"感受英伦之第二周"的那个帖子中，我曾经请你猜一猜这个2、3层楼高的球体的装置（下面那张照片是自然历史博物馆中另一个类似的装置。

This problem dates back to 1611, when Johannes Kepler conjectured that the best packing arrangement for identical spheres was arranging them in what is now called face centered cubic packing - similar to how one sees cannon balls stacked.

这个问题可追溯到1611年约翰尼斯·开普勒提出堆积等大球体最佳方法的猜想（译者注：当等大球体按照--球心位于正方体各面的中心上--的形式，并且将第一层摆放成六角形时，它们占用的空间最小，对空间的利用率可以超过74%），现在把这个方法叫做面心立体堆积法--类似于加农炮弹的堆积方式。1998年，安娜堡密西根大学教授托马斯·C·黑尔斯证明了这个猜想。

The patient was a 66-year-old male who presented with paraparesis. On examination, strength was 5/5 in both upper extremities and 3-4/5 in both lower extremities. Pricking sensation was relatively retarded below the sixth thoracic vertebra on both sides. Fine-touch sensation was limited below the ninth thoracic vertebra on the right side and below the eleventh thoracic vertebra on the left side. Responses to vibration and joint position sense were well preserved. Deep tendon reflexes were increased in his legs. He had voluntary anal contraction and preserved anal and bulbocavernous reflexes. MRI revealed dissection of the descending aorta from T4 to T10 levels with thrombus present in the false lumen, and the thoracic cord was marked atrophy, especially from T6 to T8 levels. To the best of our knowledge, no such case had been reported so far.

这是一位66岁的男性病患，到院时以下半身轻截瘫来表现，检查后发现其双上肢肌力为5/5而双下肢肌力则为3-4/5，刺痛觉在两侧第六胸椎以下异常，轻触觉在右侧第九胸椎与左侧第十一胸椎以下异常，震动觉与本体感觉则皆属正常，深肌腱反射在两下肢均有异常增强的情形，肛门的主动收缩正常且肛门反射与球体海绵体肌反射均正常，核磁共振影像显示降主动脉在T4到T10处有剥离的情形并於伪腔内发现血栓，此外，病患之胸部脊髓则有明显萎缩的现象，以T6到T8处最为明显，就目前可见的文献资料，并无类似的报告被提出。

At present study we show that aseptic flask grown plantlet of Cyrtopodium paranaese and Mormodes Jumbo Odin × Catasetum expensum can form "rootball" spontaneously at root tips and root middle parts under no influence of hormones, and then regenerate into plantlets.

吾人研究发现曲足兰与妖精兰×瓢唇兰在组织培养下，不需荷尔蒙就自然会在根的尖端或是中间形成类似原球体构造的组织，再发育成为完整的植株，此种现象在曲足兰园艺栽培上已有记载并称之为根球。

And unto the angel of the church in Sardis write; These things saith he that hath the seven irits of God, and the seven star I know thy works, that thou hast a name that thou livest, and art dead.

3：1 你要写信给撒狄教会的使者，说，那有神的七灵和七星的，说，我知道你的行为，按名你是活的，其实是死的。
