根据现场观测资料和工程实践，着重论述了风氧化带内煤层开采时覆岩破坏移动特征，风化带岩石属性和风氧化带内煤层安全开采机理的定性、定量分析。提出了风氧化带煤层开采无垮落带；受采动影响后，具阻水和抑制导水断裂带继续发展的双重作用以及移动快、变形大、回宿快、下沉大和适当加大开采厚度等新观点

The maximum run-out distance is 3200m. The three cases are studied from the Niuquangou rockslide-debris flow at the south west segment of the main seismic fault, the Chengxi rockslide at the middle segment of the main seismic fault and the Donghekou rockslide-debris flow at the north east segment of the main seismic fault.The three cases illustrates following common characteristics:(1)parent rockmass is broken under long geologic processing and weathered;(2) Rockmass was separately expanded and thrown under long-period strong ground vibration in which the vertical motion was predominant along the main seismic fault;(3)sliding mass was crashed at the exiting zone and transferred to fragment material;(4) The secondary landslide was triggered underneath the exiting zone due to the powerful crashing and shaving processes that provides more mass to debris body and cushion shape;(5) The a long run-out distance fragment flow is occurred under air layer lubrication. The air layer was pressed and turbulently flowed in the narrow-shaped valley, or laminarly flowed in the extensive flatland.

本文重点解剖了位于地震破裂带南西段的汶川映秀牛圈沟滑坡-碎屑流、位于地震破裂带中段的北川城西滑坡和位于地震破裂带北东段青川东河口滑坡-碎屑流3个典型实例，认为具有如下特征：1）岩性条件：母岩遭受长期构造动力作用，呈碎裂岩体，后期被强烈风化，岩体极为破碎；(2）抛掷效应：位于汶川地震主断裂带或附近，垂直加速度大于水平加速度，强地面运动持时长，岩体发生振胀和抛掷；3）碰撞效应：上部滑坡体发生高位剪出和高位撞击，致使岩体碎屑化；(4）铲刮效应：撞击作用导致下部山体被铲刮，形成次级滑坡，为碎屑流体提供了足够展翼和抛洒物源体积；5）气垫效应：碎屑化岩体快速抛掷导致下部沟谷空气迅速谷状圈闭和向下紊流，形成气垫效应，或者，在下部地形开阔地带压缩空气呈层流状态致使滑体凌空飞行。

The analysis of weathering crust characteristic of lower Permian Kalagang group in Malang sag, Santanghu basin suggests that the paleo-weathered crust includes weathering clay ground, strong weathering rubble layer, weak, weathering block-stone layer and unweathered rock layer in vertical and was distributed under the unconformity interface and presented in planar manner horizontally.

对三塘湖盆地马朗凹陷下二叠统卡拉岗组风化壳特征的分析，认为古风化壳纵向上分为风化粘土层、强风化碎石层、弱风化块石层以及未风化岩石层等，平面上呈面状分布于不整合界面之下，剖析该区古风化壳成藏地质条件和构造演化，探讨了可能发育油气藏类型及与风化壳的关系，并指出了该区下一步下二叠统卡拉岗组有利的勘探目标是在P2t剥蚀线与P1k剥蚀线之间范围内，其次为卡拉岗组剥蚀线以东地区。

Conventionally the layers have been divided into A, B and C horizons. The A horizon is the upper layer, containing humus and is leached and,or eluviated of many minerals. The B horizon forms a zone of deposition and is enriched with clay minerals and iron,aluminium oxides from the A layer. The C layer is the parent material for the present soil and may be partially weathered rock, transported glacial or alluvial material or an earlier soil.

传统上可将土壤分成A、B、C三层。A层是位於最上面的一层，含有腐殖质，许多矿物质在该层中沥滤和淋溶。B层是个沉积区，富集了大量的来自A层的粘土矿物质和铁，铝氧化物。C层是现在土壤的母质层，也可能是风化的岩石、来自冰河或冲积层的物质、或早期土壤遗留下来的。

The relationships between large igneous rock province, mantle plume and petroleum show that there is a low velocity-high conductive layer of mid-crust in the basin and this layer is the main source of oil and gas. Weathered granites and volcanic rocks are the best reservoir beds for hydrocarbon accumulation and the faults are the main migration pathway. It is suggested that granite and volcanic reservoirs be the future exploration targets.

通过研究花岗岩和火山岩油气藏的形成模式，指出大火成岩省、地幔柱与油气的关系表明盆地中地壳的低速－高导层可能是油气的主要来源，而花岗岩、火山岩的风化壳是油气成藏的最佳储集层，断裂则是其最主要的运移通道，花岗岩和火山岩油气藏将是未来勘探的重要目标。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
