本文在分析我国矿山安全生产严峻局势和矿山矿井安全评价国内外现状的基础上，提出矿山井下生产系统是一个由人、机、环境三方面所组成的、空间分布极其复杂的灾害系统，其安全评价应立足于人、机、环境三方面进行系统的分析与判断，并从危险因素、安全评价指标及权重、隶属函数、安全评价结构模型、综合评价方法等方面出发，以掌握矿山矿井系统的安全状态，为矿山安全管理体系的整改提供依据。

Furthermore, based on Two-term local quadrat variance algorithm, a scale decomposing method is pointed out. This thesis also evaluates the question that whether we can apply scale decomposing results into gully ordering results for getting gully ordering system keeping the same scale characteristics results.The primary works and contributions of this thesis are summarized as follows:1. Three term local strip lacuanrity algorithm (3TLSL)This thesis shows that the gliding algorithm of Lacunarity has several shortcomings, such as it can only focus on the current analysis window, and is easily influenced by some local irregular values.

Through theoretical, comparative, demonstration study and so on and the analysis of the nature and characteristics of the credit system, The thesis has put forward the conception of the Three-credit system for vocational schools: On the basis of the credit system and according to its general principle the teaching management in vocational schools divides the original credit system into three types of credits: creditof theoretical knowledge, special techniques and integrated quality with each covering a certain proportion. Each type has its own corresponding time request and evaluation forms. In each type students are, to seme extent, allowed to do some choices on their own.

本论文运用了理论研究法、比较研究法和实证研究法等研究方法，从分析学分制的本质及特点入手，提出了三元学分制的概念：中等职业学校三元学分制是中等职业学校教学管理以学分制为基础，遵循学分制的一般原则，将原来单一的学分形式分解为理论知识学分、专业技能学分、综合素质学分三类学分，三类学分之间有一定比例，每类学分有一定的课时要求和相应的评价考核办式，学生在每类学分选修中有一定的自主权，在达到规定的学分总数后即可毕业。

The agitation power consumptions in boiling systems decrease uniformly with the increase of agitation speed, whereas the relative power demand (RPD-the ratio of agitation power input of HEDT for gassed system to that for ungassed system and under the same agitation speed) can maintain at a high level for high gas loadings even when the impeller is operating with a high impeller tip speed. The gas hold-up in the boiling system is much lower than that in the cold gassed system, and the gas hold-up in boiling system increases at first and then decreases with the increase of the agitation power consumption per liquid mass P(subscript m. It implies that the boiling three-phase system has a maximum gas hold-up point. The changes of nucleation site of vapour bubble and the character of suspension of the solid particles with the rotational speed of the impeller are responsible for those behaviors mentioned.

在沸腾条件下，搅拌功率消耗随着搅拌转速的增加有所下降，但HEDT桨具有较高的载气能力，即使在高叶端线速度下，相对功率消耗仍能保持在较高的水平；沸腾体系的气含率随单位质量流体输入功率的增加表现出先增后减的规律，即存在气含率的极大值，蒸汽成核位置和固体颗粒悬浮特性随搅拌功率增加而改变是造成上述行为的主要原因；沸腾体系中的气含率远远低于常温通空气体系。
