克莱因瓶

The Klein bottle's inside is its outside.

该克莱因瓶的内部可以说是它的外面。

Chain complexes of projective space and Klein bottle are well known.

射影空间和克莱因瓶链复合物是众所周知的。

Chain complex of Klein bottle is presented

克莱因瓶链复杂，提出

Only four surfaces are possible for such embedding:the sphere,the torus,the Klein bottle and the projective plane.

这样的嵌入只能在球面、环面、克莱因瓶和射影平面上实现，其五边形面的个数分别为12，0，0和6。

This is one of a series of glass Klein bottles made by Alan Bennett in Bedford, United Kingdom for the Science Museum, London. It consists of three Klein bottles, one inside another. A Klein bottle is a surface which has no edges, no outside or inside and cannot properly be constructed in three dimensions.

其实除了用玻璃吹制，如果我们把两条莫比乌斯带沿着它们唯一的边粘合起来，也可得到了一个克莱因瓶（当然不要忘了，我们必须在四维空间中才能真正有可能完成这个粘合，否则的话就不得不把纸撕破一点）。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
