碎屑

Grainstones are the main part of the section, among which the oolites, intraclast limestones and most bioclast limestones are cemented by sparry calcite.

颗粒灰岩在剖面中占绝大多数，其中，鮞粒灰岩、內碎屑灰岩和多数生物碎屑灰岩均为亮晶方解石胶结。

The main lithologic characteristic is that the rock types are dominated by light-colored clastic rocks reflecting the oxidation environment with a low maturity. The grain size distribution and sedimentary structure show that the rocks have the sedimentary characters of both gravity currents and tractional currents. Plant fragments are lacking and bioturbation structures are abundant and cyclic. Sandbodies are distributed in a ring shape.

其主要岩性特征为：岩石类型以反映氧化环境的浅色碎屑岩类为主，成熟度较低，粒度分布和沉积构造反映其兼有重力流和牵引流的沉积特点，植物碎屑贫乏而生物扰动构造丰富且具周期性，砂体呈环带状分布。

Like cedar shavings, pine shavings are also believed to be hazardous to the health of small mammals, though this is more widely disputed.

和香柏树碎屑一样，松树碎屑也被认为是对小型哺乳动物的健康有害的，尽管这种说法还有很多的争议。

High-quality clastic reservoirs deep-buried in superimposed basin s of China, with many layers and wide distribution, are the importantoil and gas reservoir bodies and exploration targets, which are also key conditions to increase in the exploration effect in seeking for large-scale,high-quality clastic reservoirs in deep superimposed basin s.

我国叠合盆地深层碎屑岩的层系多、分布广，是重要的油气赋存单元和勘探目标，而寻找较大规模的优质碎屑岩储层是提高叠合盆地深层勘探效果的重要前提。

There are 4 end members of volcanic clasts, including catapult airfall, ejection airfall, base surge and volcanic clasts flow.

与火山作用有关岩相有4种端元的火山碎屑岩相：弹射坠落爆发空落相、喷射降落爆发空落相、热碎屑流相和热基浪相。

If the volcanic clasts were deposited on volcanic slope and/or fluvial plain, they would occur in the 4 faceis mentioned above or in alluvial fan and braid stream.

According to the sequence model, the topography is expanse and flatness, there are relative shallow water, stable structure, flattened basement in intercontinental rifting basin, and the provenances changed gradually from terrigenous clasts to intra-basin carbonate. So, there are some corresponding characteristics in sequence genetic framework:① Sequence material components are carbonate rocks, and mixed sedimentary series of carbonate rocks and clastic rocks.

就层序模型来讲，陆内裂陷盆地地势宽缓，具有水体相对浅、构造稳定、基底平缓、物质来源由陆源碎屑逐渐向盆地内的碳酸盐转化，因此，其相应的层序成因格架具有如下主要特征：①在层序物质构成方面，主要由碳酸盐岩构成，其次是碳酸盐岩—碎屑岩的混合沉积岩系。

The exposed massive cold-seep carbonates provided substrate for the encrustations of corals as well as coralline algae and might have played a crucial role in the initial development of coral reefs in a siliciclastic paleoenvironment of active tectonic setting. This is probable the first case of the world that cold-seep carbonates acting as initial colonization hardgrounds of hermatypic corals and corallines.

在此基底泥岩快速浅化的过程中，出露的块状冷泉碳酸盐岩成为不稳定地体构造背景中，珊瑚与珊瑚藻等表覆生物在矽质碎屑环境生长的硬底质，可能在礁体的最初发育扮演关键性的角色；此种冷泉碳酸盐岩成为造礁珊瑚与珊瑚藻在矽质碎屑古环境中最初生长硬底质的现象，很可能为世界首例。

On the basis of the researching of facies、 petrology、 cathodoluminescence analysis, this paper concludes that the terrigenous clastics in Pingyipu Formation were mostly originated from Motianling palaeo-peninsula lied to its north, and sands in distributary channels、 braidedriver in estuaries、 deltas and in littoral zone in hybrids could be derived from Middle-Sichuan Palaeoland with Peng-Guan Highland.

对早中泥盆世浑水陆源碎屑沉积及混合沉积的沉积相、岩石学、阴极发光等研究分析，作者推测，该区陆源碎屑主要来自北边的摩天岭古半岛，而分流河道、辫状河充填及混积滨岸砂则可能以川中古陆和彭灌高地为主要源区。这一点与过去通常认为的主要来自彭灌岛和轿子顶古岛差别较大。

Combined with previous studies, we suggest that the 1100-2200 Ma zircons perhaps originate from the China North Craton, while the zircons of 520 Ma may stem from Jiamusi massif.

根据目前有关年代学研究成果，推断1100~2200 Ma碎屑锆石可能来源于华北克拉通，而样品中的520 Ma的碎屑锆石则可能来源于佳木斯地块。

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。
