陆地动物

We will walk across the land ,following the footprints of big animals .

我们将穿行于陆地，追寻大型动物的脚印。

They came to form flat animal, star-shape animal, annelid, arthropod and amniote, such as rabbit, dog, horse, sheep, monkey, orangutan and even human.

后来一些生物脱离了水域来到陆地上生活，逐渐形成扁形动物、星虫形动物、环节动物、节肢动物、脊椎动物、兔狗马羊猴、猩猩乃至人类。

Amphibious animals can live both in water and on land.

两栖类动物在水中和陆地上都可以生活。

The polar bear is the second largest land carnassial beast in the world. Male bear's length reaches 240-260 cm, usually weighed about 400-800kg.

北极熊是世界上第二大的陆地食肉动物，雄性北极熊身长大约240-260cm，体重一般为400-800公斤。

Myriapod animals were probably one of the invertebrate animal groups that first colonized the terrestrial ecosystem during Early Paleozoic.

多足动物可能是最早入侵陆地环境的无脊椎动物之一。

Stationary animals are found in water, but no such creature is found on dry land.

稳定的动物在水中被发现，没有那样的动物在陆地上被发现。

Enigmatic small elongated wormlike terrestrial invertebrates of damp dark habitats in warm regions; distinct from the phylum Annelida; resemble slugs with legs and are sometimes described as the missing link between arthropods and annelids.

身体细长、比较神秘的陆地无脊椎动物，生长在潮湿阴暗的温带地区；与环虫动物门截然不同；与蛞蝓的腿相似，有时被认为介于环节动物和节肢动物之间。

The phylogenetics and evolutionary history of Myriapoda are now central to arthropod systematic research, as the Pancrustacea is commonly accepted as a natural group.

多足动物可能是最早入侵陆地环境的无脊椎动物之一。

At up to 92 feet (28 meters) and 50 tons, these sauropods were much larger than any land animal alive today.

在高达92英尺（28米）和50吨，这些蜥蜴类动物要远远大于任何陆地上今天活着的动物。

Lore has it that the largest land mammal elephants are afraid of mice, but scientists have now discovered that elephants are truly afraid of bees - and that the pachyderms even sound an alarm when they encounter them.

据说，陆地上最大型的动物大象怕老鼠，但科学家如今发现，大象真正怕的是蜜蜂；当这种厚皮大型动物碰到小蜜蜂时，甚至会发出警报。

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。
