Cases were the diseases with two or super-two kings of abnormity, including 25 cases' chronic obstructive pulmonary disease, 7 cases' pulmonary alveolar proteinosis and 5 cases' viral pneumonia. The DGGO had presented mosaic-fashion's shadow or geographic change or crazing paving pattern, or the DGGO had centrally distributed with lobular central node, acinose node and interstitial fibrosis. Conclusion DGGO may be seen in various diseases.

两种因素或两种以上因素异常的疾病有慢性阻塞性肺病25例、肺泡蛋白沉积症7例及病毒性肺炎5例，慢性阻塞性肺病为通气-血流障碍所致，其磨玻璃影与低密度区形成马赛克样改变，常伴有桶状胸；而肺泡蛋白沉积症及病毒性肺炎同时具有气腔和固有肺结构异常，其磨玻璃影是间质性病变与实质性病变共同作用的结果。

Results show that the Spiti shale in Zanskar terminated 15Ma later than that in southern Tibet, while the lowermost Cretaceous quartz sandstone in Zanskar appeared 18Ma later than that in southern Tibet. The age of volcanic sandstone in southern Tibet is very poorly time constraint and their deposition occurred somewhere within Berriasian～early Albian. In Thakkhola, the Chukh Group volcanic sandstone are of late Hauterivian-early Albian age (duration about 20Ma), while in Zanskar, the volcanic sandstones facies only appeared in Albian (duration of less than 10Ma). Therefore, it can be concluded that the onsets of both quartz sandstone and volcanic sandstone occurred earlier in eastern Tethys Himalayas than in western Tethys Himalayas .

侏罗纪末～白垩纪初印度大陆的北缘同时期存在大陆向上挠曲，导致陆源碎屑输入量的快速增加，石英砂岩广泛存在；早白垩世火山岩屑砂岩对应着的印度大陆北缘地层侵蚀加深，使得较深部的深成火山岩暴露并遭受侵蚀；石英砂岩和早白垩世岩屑砂岩所代表的印度大陆剥露时间在空间上的&东早西晚&，说明构造运动首先是从特提斯喜马拉雅的东部开始（大印度与澳大利亚的彻底分离），然后逐渐波及西部的，东西时间差为15～20Ma；由于地壳均衡作用，大陆分离后原先地壳挠曲转变为地壳下沉，发生强烈的构造沉降，故Albian之后沉积一套深水环境下的海绿石、磷酸盐和黑色页岩沉积。

The unique geographic position of shelf and marginal sea causes the material supply of seafloor sediments plenteous and the material sources of them diverse. As terrigenous materials being input into the sea continually and a great deal of authigenous minerals coming into being, the sediments can be used to study the change of sea level and the meterail and energy exchange between the sea and the land.

陆架和边缘海独特的地理位置决定了海底沉积物物源的充足与多样性，陆源物质源源不断地通过河流输入到海洋中，同时大量的自生矿物在海洋中生成，因此研究陆架和边缘海海底沉积物，可以为研究海平面变化、海陆之间物质和能量的交换等作用提供信息。

Furthermore, in order to improve the interpretation of the deltaic sedimentary record, e.g., to identify climate and environmental changes using the record, the various parameters derived from analyses of the cores should be standardized by evaluating the temporal changes caused by early diagenesis and decay, and by determining the rate of deltaic shoreline changes which control the relative position of the record within the deltaic sedimentary system.

此外，在长江三角洲沉积记录的分析方面，为了更好地提取气候、环境演化信息，应充分考虑沉积记录形成后所经历的自身变化（如成岩作用变化、分解和衰变等）和相对于岸线迁移的空间位置变化。

This kind of sequence indicated the mutation of sedimentary environment of the epicontinental sea basin.

Increase of that clast of sedimentary rock, high-grade metamorphic rock and unstable heavy minerals shows tectonically active setting and obvious uplift of Bogda Mountain during the Late Jur.

新疆博格达地区中—新生界碎屑成分自中侏罗世的中晚期开始发生了巨大变化，主要表现在：自中侏罗世晚期开始，沉积重矿物组合及相对含量发生较大变化，不稳定重矿物、较高级别变质岩岩屑明显增多，显示此时发生的物源属性变化及构造活动的存在；自侏罗系西山窑组沉积晚期开始，砂岩碎屑成分中的沉积岩碎屑明显增加，显示盆缘沉积岩物源的隆升和剥蚀作用。

The ore-bearing fluid of the Dabaoshan deposit is related to magmatic thermal dynamic process, and volcanogene hydrothermal sedimentary polymetallic deposit on seabed was formed. The Fankou Ore-bearing fluid is related to circulation hydrothermal in deep formation, and middle-lower temperature Pb-Zn-Ag-Hg polymetallic sedimentary deposit by sea-floor thermal spring and overflowing was formed. The Hongyan ore-bearing fluid is related to the compaction water that formed by the basin's lithogeny process, and low temperature and pyrite only was formed.

大宝山型流体与岩浆热动力作用有关，形成海底火山热液沉积多金属矿床；凡口型流体与深部建造的循环热液有关，形成中低温海底热泉喷溢沉积铅锌银汞矿床；红岩型流体与盆地成岩压实水有关，形成低温单一黄铁矿矿床。
