圆石头

This one, and, by scratching it on a stone, I made it round.

就是这块，我把它在石头上磨圆了。

Most of the stones of Stonehenge stand in incomplete formations of circles.

Not the ignorance, but the ignorance of ignorance, is the death of knowledge. By Whitehead

很抱歉，这个不是恐龙蛋，除了石头是圆的外和蛋没有什么关系。

When the soil relative water content is 80%, the chloroplast and mitochondria cristae were regular. When the soil relative water content is 100%and 60%, the chloroplasts became roud in shape.There were bigger giqantic starch grains and fat droplets in the chloroplasts. Mitochondria cristae became swollen. When the soil relative water content is 40%and 20%, thylakoids became swollen and disorder in leaf cell, mitochondria cristae became obscured .

5在土壤相对含水量为80%时，叶绿体和线粒体能维持其结构和膜的完整性；在土壤含水量为100%和60%时，毛桃和石头扁桃叶片中的叶绿体变圆，出现大颗粒淀粉和脂类小滴，线粒体嵴膨胀；在土壤含水量为40%和20%时，叶绿体类囊体紊乱肿胀，线粒体嵴模糊或溶解。

I must look into that dark cave,where through boulders and scowling stones,trickles a tiny stream.

我一定要去那个黑洞里查找，在那儿，一条小溪从圆的，有皱纹的石头中流出。

Jack came lagging in late one afternoon, drank his two bottles of beer cooledin a wet sack on the shady side of the tent, ate two bowls of stew, four ofEnnis's stone biscuits, a can of peaches, rolled a smoke, watched the sun

drop。这天接近傍晚时，杰克慢条斯理走过来，喝下两瓶放在帐篷阴影处湿袋里冷藏的啤酒，吃了两碗炖肉，吃了四颗恩尼司硬如石头的软圆饼，一罐桃子，卷了一根烟，欣赏日落。

Barely light and yet--- cold shouldering clipped laurel, nippling the road--- I subvert sculpture, the old mode; I skin I dimple clay, I flesh, I rump stone.

几无光线但是——寒气以肩膀顶着剪过的月桂，以乳头指明道路——我推翻了雕塑这种旧模式；我有皮，令泥土荡出涟漪，我有肉，让石头长出圆臀。

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。
