| 1. | Hst , hubble space telescope
哈勃空间望远镜 |
| 2. | Water body is shallow and sediments are coarse in lst and hst , but in tst , being deep and fine
低水位体系域和高水位体系域水体较浅，沉积较粗，而湖进水位域则水体较深，沉积较细。 |
| 3. | The upper permian - triassic is subdivided into two sequences with lst , tst and hst systems developed for each sequence
把上二叠统三叠系划分为两个层序，每个层序发育lst ， tst和hst等3个体系域。 |
| 4. | This paper briefly introduces the arrangement of hst on middle and small tractors . it has certain advantages and possibility
摘要经过结构布置，认为将hst应用于中、小功率拖拉机上具有明显优势，而且切实可行。 |
| 5. | The insert shows the three chandra sources closest to the supermassive black hole , overlaid with the intensity contours from the hst image
小图显示距离大黑洞最近的3个x射线源，影像上面的红线是透过哈勃太空望远镜所得的光度等值线。 |
| 6. | It is fitting that the hst , named after edwin hubble , should obtain a picture that would greatly enhances our understanding of the nebula that hubble himself discovered 85 years ago
从哈勃望远镜拍得的照片，去了解哈勃于八十五年前所发现的星体，可说是最适合不过。 |
| 7. | By performing a detailed analysis of the hst images , kwok and hsia found a series of nine rings along the axis of this hourglass - shape nebula . these mysterious rings are circular in shape and lined up precisely one after another
郭新教授和夏志浩详细分析这些照片时，发现有九个神秘的环，一个接一个的环绕著这星云的轴心。 |
| 8. | In the end the significance and the contents of this thesis were presented . in the chapter 2 the components and the requirement to main element were carefully analyzed . several main drive schemes were studied
第二章详细分析了hst装置主要元件的选用要求，对zjm系列液压马达提出了自己的设计方案，进行了结构和原理设计。 |
| 9. | One of the main contents of continental sequence stratigraphy is dividing the three - order sequence into " lst , tst and hst " , representing three stages of a lake basin deposition
摘要陆相层序地层学的一个主要内容是将三级层序划分为“低水位体系域、湖进体系域和高水位体系域”等三个水位域沉积体系，分别代表着一个湖盆沉积的三个阶段。 |
