半深海的

It shows that the sedimentary facies are submarine fans deposited by gravity flow at the bathyal depth.

综合应用沉积岩石学、地质学等多学科理论，全面分析了F4层的岩石学性质、沉积构造特征、测井曲线特征、古生物特征等，认为F4层的沉积相为陆隆-半深海环境下重力流沉积的海底扇。

The water depth had increased since Late Te r tiary and reached to high stand in Early and Middle Pliocene (outer neritic to b athyal environment), and then decreased.

研究认为崖19-1-1井晚第三纪以来古水深变化的总趋势为逐渐增大，至上新世早中期出现外浅海至半深海环境，为古水深最大时期，随后水深则逐渐减小。

包古图组主要为一套深海―半深海相的灰、灰黑色薄层状凝灰质粉砂岩、凝灰质泥岩，与灰绿色、灰色薄层状沉凝灰岩不均匀互层。

Bao ancient group plans for a major deep-sea - a half deep in the ash, black ash-like TLC tuffaceous siltstone, shale tuffaceous, with gray green, with thin gray-tuff interbedded uneven.

包古图组主要为一套深海―半深海相的灰、灰黑色薄层状凝灰质粉砂岩、凝灰质泥岩，与灰绿色、灰色薄层状沉凝灰岩不均匀互层。

Paleozoic stratum can be separated east and west stratigraphical areas, according to lithological character and palaeontological information, contacted relationships and diversification of stratigraphical units in horizontal and vertical etc. The stratums in west area can be divided Devonian-Carboniferous Nanduan formation and Permian Laba formation, which is passive continental margin-bathyal depositional sequences comprised argillaceous and detrital rocks, small siliceous and carbonatite in upper. The stratums in east area can be divided lower-middle Devonian Wenquan formation and middle-upper Devonian Manxin formation, upper Devonian-lower Carboniferous Pingzhang formation, Carboniferous-Permian Yutangzhai formation, middle Permian Damingshan formation, upper Permian Shifodong formation respectively, moreover, middle-upper Permian Huoju formation is exposed in Menglian area.

根据地层的岩石组合、古生物、接触关系和地层单位的纵横向变化等特征，晚古生代的地层明显的可分为东、西两个地层小区：东部地层小区从下至上可划为泥盆—石炭系南段组、二叠系拉巴组，为一套泥质岩、碎屑岩，上部夹硅质岩、碳酸盐岩建造，属被动大陆边缘斜坡—半深海沉积；西部地层小区由下至上划分为下—中泥盆统温泉组、中—上泥盆统曼信组、上泥盆—下石炭统平掌组、石炭—二叠系鱼塘寨组、中二叠统大名山组、上二叠统石佛洞组，此外，在孟连一带尚出露中—上二叠统火居组。

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。
