But there is defect in present commonly used calculation formula of rockfall movement characteristics that there is no parameter can characterized the mass of the rock. So the computed result can not reflect the influence of the different rock mass to the movement characteristics and is quite different from the actual movement of falling rock.

但目前普遍采用的落石运动特征计算公式中存在没有表征落石质量的参数的缺陷，这使得计算结果不能体现落石质量的差异对其运动特征的影响，且与落石实际运动过程存在较大差异。

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。

He proves, furthermore, that the Mass of the Gregorian Sacramentary, such as we have it, is of Gallican origin (since the belief in the bodily assumption of Mary, under the influence of the apocryphal writings, is older in Gaul than in Rome), and that it supplanted the old Gelasian Mass. At the time of Sergius I (700) this feast was one of the principal festivities in Rome; the procession started from the church of St. Hadrian.

他证明，此外，地下的阳历Sacramentary ，如我们，是原产地的高卢圣（自认为在担任身体玛丽的影响下，在未经著作，是中老年人比高卢人在罗马），它取代了旧的Gelasian马萨诸塞州的时候塞尔吉乌斯口（ 700 ）这是一个节日的主要庆祝活动在罗马举行的游行开始从教堂的圣哈德良。

The study of the origin of Mass leads to the understanding of Haydn's Mass, and his contributions to the sacred music in the history.

从弥撒曲的起源发展探讨海顿的弥撒曲作品，了解海顿弥撒曲的音乐特质及海顿在宗教音乐上的贡献。

ResultsFour cases are huge mass of solid oval with integrity of coat and smooth, clear edge; they grow at the right middle or right posterior inferior mediastinum, along the spine, no expansion of intervertebral foramen and down to enter into crura of diaphragm; their density are less uniform, in two masses with a sand calcification image. In plain scanning, the CT values is 23~33Hu; in dynamic state enhancement scanning of 4 cases the mass are not enhanced or not obviously strengthened at arterial phase, and have a linear strengthen at venous phase.

结果4例均为巨大实性椭圆形肿块，肿块包膜均完整，边缘光滑清晰；4例肿块分别位于右后中下和右后下纵隔，均沿脊柱生长，无椎间孔扩大，向下伸入膈脚后；4例肿块密度均欠均匀，2例肿块伴有一砂粒状钙化影，平扫时CT值为23～33 Hu；动态增强扫描时动脉期4例肿块均呈无强化或强化不明显，静脉期4例肿块内均见有一条线形强化。

The paper is based on the theory of inter-function between water and rock, and losing energy in rock mass, brought forward that the water flow has head loss during water flow intruding through the coal seam effective water-resisting layer and energy waste concept for splitting rock mass, and analyzed the form of the remaining water pressure. Through the simulation experiment in the preventing water capability of water-resisting rocks in the coal seam scaleboard, studied the law, character of the losing in water head waste and the relation to pressure, water-resisting of hydrogeology and engineering geology character. Brought forward the new method of calculating the water inrush coefficient.

通过理论分析和实验研究，本文得出以下结论：高承压水在沿煤层底板隔水层导升过程中存在着明显的压力水头损失；同一地层条件下，煤层底板承压水水头压力越大其导升过程中的水头压力损耗就越大；同一水头压力条件下，地层的渗透性越差其阻水能力越强，水流导升过程中的水头压力损耗也越大；在同一介质中，当初始水头压力不同时，水流在导升过程中水头压力的衰减不同，在同一隔水介质中底板含水层水头压力越大其沿隔水层导升过程中的水头损耗也就越大，水头损耗随底板隔水层水头压力增加而呈递增趋势，另外它们相应的水头衰减速率也呈递增趋势，煤层底板隔

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
