喷发

Cleveland Volcano, located in the Aleutian Islands southwest of Alaska, failed to produce an eruption and the plume of ash detached from the volcano two hours after it had formed.

克利夫兰火山，定位于阿留申群岛西南的阿拉斯加，已经失效去制作一个喷发和那羽毛状的火山灰分离自火山喷发2小时之后它已经成型。

Saint Helens seemed at the time of the 1980 eruption, it was actually a relatively small eruption compared to other Andesite volcanoes such as Mt.

圣海伦斯似乎在当时的1980年喷发，它实际上是一个相对小的喷发较之其他安山岩火山如山。

Sub-volcanic rocks include andesitic porphyrite, rhylitic porphyry, cryptoexplosive breccia as well as autobreccia etc.(2) Volcanic lithofacies——through the observation of cores, identification of thin sections and interpretation of well logs and seismic data, there are 8 kinds of lithofacies for the volcanic rocks of Yingcheng Formation are identified: fallout facies, effusion facies, pyroclastic flow facies, base surges facies, lahar facies, eruption-sedimentary facies, subvolcanic facies and extrusion facies.(3) Three types of eruption——i. e. explosion, effusion and surge.(4) Two kinds of eruptive environments——Subaerial (e. g. volcano in Well Shangshen 3) and subaqueous .(5) Three remarkable volcanic apparatus in Shengping-Wangjiatun area——layered, micro-shield and cone volcanoes according to volcanic processes and lithofacies distribution.

次火山岩有安山玢岩、流纹斑岩、隐爆角砾岩及自碎角砾岩等；(2)火山岩相——通过岩芯观察、镜下鉴定、测井与地震资料解释，营城组火山岩中发育8种岩相类型，即爆发空落相、溢流相、火山碎屑流、基底涌流相、喷发沉积相、火山泥石流相、侵出相和次火山相等；(3)火山喷发的形式——有爆发、溢流和涌流三种；(4)火山喷发环境——有陆上(如尚深3井火山)和水下两种；(5)火山机构类型——根据火山作用特点和岩相分布特征，在升平—汪家屯地区识别出三类截然不同的火山机构，即层火山、微型盾火山和渣锥火山。

火山喷发的活火山喷发的，与活火山喷发有关的，由活火山喷发而组成的

Smoke in the car driving, mountain continued to erupt smoke darkened the sky, cars driving in the dust, volcanic eruptions with special phenomenon, local time, April 17, 2010, Iceland, Eyjafjallajokull volcano continued to emit smoke,...

汽车在烟尘中行驶，山持续喷发烟尘天空昏暗，在烟尘中行驶的汽车，火山喷发伴随特殊现象，当地时间2010年4月17日，冰岛，Eyjafjallajokull火山持续喷发出烟尘，。。。

It can be subdivided into two phases of Plinian eruption, the first is named the Chifeng phase and the second the Yuanchi phase.

这次大爆发分为两次普林尼式喷发：第一次喷发称赤峰期，第二次喷发称园池期。

This paper studies the correlation between the maximum height s of the Plinian volcanic eruption columns and mass flux of the volcanic eruptions according to measurement data acquired from active volcanoes around the world.

Plinian式火山喷发柱最大高度是研究火山喷发对环境、气候影响时空范围的重要物理学参数，在分析了影响Plinian式火山喷发柱最大高度诸因素的基础上认为，火山喷发的质量通量是反映火山喷发柱最大高度最有效并且在实际中可以进行测量的参数之一，以此为基础，利用目前实测的火山喷发柱最大高度的数值与火山喷发质量通量的结果，建立两者的相关方程为：H＝0。

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。

The spacial-temporal characteristics of the climate response to volcanos connect with the latitude location, season and strongness of volcanic eruption, Series analyses also confirm the obvious correspondence between the volcanic eruption and the climate change.

时序叠加研究表明，强火山喷发可造成半球和全球年平均温度下降约0.3℃，持续时间约两年；火山活动对气候影响的时空分布特征和火山活动特征：如火山喷发强度、喷发位置和季节等等有关。

Volcanic eruptions happened: the 1st and 3rd are fissure eruptions of intermediate-basic basaltic andesite and are resulted from the structures of active period, while the 2nd belongs to central eruption of neutral trachyandesite and is derived from the structure of stabilized period.

其间包括3次火山喷发活动，第1次和第3次为中基性玄武安山岩的裂隙式喷发，为构造活动期的产物；第2次为中性粗安岩的中心式喷发，为构造稳定期的产物。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
