碎屑

Optical microscope, scanning electron microscope and X-ray diffraction analysis have revealed that dawsonite mainly occur in the feldspar-rich sandstone and pyroclastic rocks, either as cements filling inter-grain pores as radical, bunchy, rosette, intricately trichoid, and platy collectives, or as replacement of feldspar and lithic grains with bunchy and paty shapes.

片钠铝石主要发育在油气储层或CO2气储层中富含长石的砂岩和火山碎屑岩中。在含片钠铝石砂岩和火山碎屑岩中，片钠铝石以放射状、束状、杂乱毛发状、球状和板状等集合体充填孔隙，或呈束状和板状交代长石和岩屑。片钠铝石及其共生的铁白云石都是最晚形成的自生矿物组合。

The average greatest grain-sizes of lithic fragments and pumice fragments in pyroclastic flow deposits decrease with increasing distance from the crater, indicating that gravity sorting and mechanical wearing did occur during the transportation of the pyroclastic flow.

火山碎屑流堆积中的岩屑和浮岩的平均最大粒度随着离开火山口距离的加大而减小，反映火山碎屑流搬运过程中存在重力分选和机械磨损作用。

Volcanic sedimentation is a frontier realm between volcanology and sedimentology.

在此基础上，本文提出了新的火山碎屑物、火山碎屑岩岩性和火山碎屑岩成因分类。

Debris necrosis of lymph node is not the specific changes of KD. In the tuberculosis of lymph node,① debris necrosis is obvious, but it tends to be caseous nercrosis;② histiocytes, macrophages and foam cells are hyperplasia in the necrotic area or lymph sinus, moreover, epithelioid cells can be found and they tend to be form granuloma;③ numbers of neutrophils infiltrate in the necrotic area;④ the etiologic assay of acid fast bacterium tuberculosis bacterium is positive;⑤ typical clinical manifestation is insufficient.

淋巴结碎屑性坏死并非KD特有病变，诊断KD需先除外有明显碎屑性坏死的淋巴结结核病，后者主要表现：①碎屑性坏死虽明显，但趋于干酪样坏死；②坏死区内或同时在淋巴窦内，组织细胞、巨噬细胞和泡沫细胞增生，并演变为上皮样细胞和趋于肉芽肿形成；③坏死灶内、外可有数量不等的中性粒细胞浸润；④抗酸杆菌／结核杆菌病原学检测阳性；⑤缺乏KD的典型临床过程。

Detrital sedimentation is the direct record in basin for mountain uplift and erosion. The analysis of detrital minerals, including heavy minerals, is a key means for basin-mountain coupling studies.

碎屑沉积是山脉隆升和盆地沉积的直接记录，包括碎屑重矿物研究在内的碎屑沉积物的分析是开展盆山耦合研究的必要手段。

The eruptive pattern of the Chifeng phase is: Plinian column (the Chifeng pumice fall deposits)→pyroclastic flow (the Changbai pyroclastic flow deposits)-lahar mainly triggerd by pyroclastic flow. The eruptive pattern of the Yuanchi phase is from Plinian column (the Yuanchi pumice and ash fall deposits)→pyroclastic flow (the Bingchang pyroclastic flow deposits).

赤峰期喷发模式为：普林尼式喷发柱－火山碎屑流－火山泥流，主要由火山碎屑流诱发火山泥流；园池期火山喷发模式为：普林尼式喷发柱－火山碎屑流。

Based on the Visual Basic 6.0 platform, some new programs for various purposes are developed, such as for the calculation of tephra diameter parameters in the light of Sequential Fragmentation Theory by Wohletz

介绍了在VisualBasic6 。0平台下，碎屑粒径参数、岩浆黏度、结晶压力、喷出压力、给定时间段和特定区域的各高度层风参数、岩浆动力学参数、喷出物总量、抛射体分布、坍塌阶段碎屑分布和扩散阶段碎屑分布计算等各程序的主要结构及主要功能。

Organic matter, pH, cation exchange capacity and contents of potassium, sodium, magnesium, copper, zinc, manganese, cobalt, iron, selenium, iodin and fluorin were determined of rock and soil samples from six main geological background areas within the main ruminant production base, in Yunnan Province, China. Results showed: 1 the red earth area of Paleozoic basalt and red earth area of carbonate the highest; the yellow-red earth area of mixture of carbonate, clasolite and basalt follows, except for its content of Co, which is relatively lower; and the purple earth area of Mesozoic clasolite, the yellow-red earth area of clasolite and the dark red earth area of Precambrian metamorphite are the lowest

对云南省反刍动物生产基地所属的6个主要地质背景区的土壤和岩石样品的K、Na、Mg、Cu、Zn、Mn、Co、Fe、Se、I和F元素及土壤的有机质、阳离子交换量和pH进行测定分析，结果表明：晚古生代玄武岩红壤区和碳酸岩盐红壤区土壤各种矿质元素都比较高，有机质含量与CEC都较高，特别是Ⅴ区最为显著；碳酸岩盐、碎屑岩和玄武岩混合型黄红壤区除了Co含量较低外，其他元素含量都居中等或偏上水平，有机质含量与CEC仅次于第1类背景区；碎屑岩紫色土区、变质岩赤红壤区和碎屑岩黄红壤区大多数矿质养分相对都比较低，有机质含量与CEC最低。
