5Under powerful offensive denfense,failing in resolving the offending problems is one of the leading reasons that it lost in the world men ' s basketball championship;the quantity of the fast attacks from chinese team lags behind a lot,compared with the opponents.Moreover,the difference of the quantity of success,the gap of score and fast attacks after stealing is very obvious; scoring could only be attributed to receive and shoot,play by oneself and free throw.Scoring method is simple and unscattered;strategic offenses lag behind the opponent obviously.Both free throw after active offense and rebound control could not defeat the rivals.The stealing and offense succeeding percentage also fall behind. The offense efficiency lags more behind;the number of two – piont shot lags behind the opponent while the field goal percentage ranks a little higher than opponent.The number of three-point shot is similar, but the field goal percentage is obviously different;chinese team ' s front court rebound falls behind the opponent apparently.However,the second offense scoring is a little higher;chinese team ' s assists lags behind a lot;chinese team ' s stealing lags behind a lot;chinese team ' s turnovers distingguish a lot with opponents.

在强对抗的攻击性防守下中国队不能解决好进攻的问题是世锦赛失利的最主要的原因之一；中国队的快攻次数与对手的差异具高度显着性，成功次数的差异具显着性，得分的差异具高度显着性，断球后发动快攻的差异具显着性；得分主要集中在接球得分、单打得分、和罚球得分这三个方面，得分手段单一而且集中；战术进攻与对手呈差异有高度显著性，作为主动进攻的罚球和争夺篮板球都比对手低；抢断与对手的的差异具显着性，进攻成功率与对手的有一定的差距，进攻效率的差距更大；2分球的投篮次数与对手的具有高度显著性差异，命中率比对手稍高一点，3分球投篮次数相当，命中率具有显著性差异；中国队的前场篮板球与对手相比具有显著性差异，但是二次进攻得分却比对手略高一点；中国队与对手的助攻相比有显著性差异；中国队的抢断与对手相比具有高度显著性差异；中国队的失误与对手相比具有高度显著性差异。

As far as free proline content was concerned, that of EI plants was less than EF plants due to higher water-holding ability of EI plants (such as in field plot and field pot sustained drought stress), or due to less damage of membrane of EI plants (such as field pot cyclic drought stress and greenhouse osmotic stress).

至于脯氨酸含量的变化，或是由于感染植株保持体内水分的能力更强（固定样地和田间盆栽持续性干旱胁迫下），或是由于感染植株叶细胞膜结构受到的伤害程度更小（田间盆栽周期性干旱胁迫和温室渗透胁迫下），感染植株的游离脯氨酸含量均低于非感染植株。

The influence of high temperature and high pressure on foaming agent's properties in opened and closed system, and influence of the change of foaming agent's properties on foaming capacity and foam stabilizing capacity are also studied. The multiple regression theory is used to establish the quantitative characteristic functions of foaming agent versus temperature and pressure. Based on the Gibbs Principle, the quantitative characterization is carried out on relation of foam system's free energy versus its surface tension, surface area and concentration, and the analysis of energy concluded that the disintegration of the foam is inconvertible. At the same time, the influence of change of foam's shape and structure on distribution of reservoir temperature and pressure is qualitatively described, and the coupling mechanism between temperature field, pressure field and chemical field is systematically expounded.

But in realistic reason, the absurdity of the personnel system becomes the parent and teachers toward what student bring pressure emollient to borrow;, The family becomes the student to increase the negative important place, it is student the lessons burden aggravate of motive source and direct source, and became student's mental state to increase negative important source;High test conductor's baton BE also result in this phenomenon of important reason, an acceptance score line stopped the teacher's throat, also taking out to beat the student;The slippery 坡 of the occupation morals of teacher make it the mental acceptance ability of the regardless of student and the healthy body of the student, pass to increase student's lessons to make up the shortage on oneself's teaching, this makes some teachers unilateral to emphasize the result but threw to lose the teacher's original intention then;Lack the emollient direct mechanism, foster the teacher and don't go to the character of raise the oneself, don't go to the science skill of raise the teaching, but measures this to breach the method of science in brief to raise the deceitful examination score of student with the enlargement homework, is not science ground passes to raise student's character, raise the teaching result, but use and should try the educational way leading the student copes with the examination with the speculation prosperity method.

而在现实原因中，人事制度的不合理成为家长和教师向学生施加压力的有力借口；，家庭成为了学生增负的重要场所，更是学生课业负担加重的动力来源和直接来源，并且成为了学生心理增负的重要来源；高考指挥棒更是造成这一现象的重要原因，一条录取分数线勒住了教师的喉咙，也抽打着学生；教师职业道德的滑坡使其不顾学生的心理承受能力和学生的身体健康，通过增加学生课业来弥补自己教学上的不足，这便使有些教师片面强调成绩而丢失了教师的初衷；缺乏有力的监督机制，助长了教师不去提高自己的素质，不去提高教学的科学本领，而是用加大作业量这一简单的违反科学的方法来提高学生虚假的考试分数，不是科学地通过提高学生素质，提高教学效果，而是用应试教育的方式指导学生用投机繁荣方法应付考试。

The influence factors are divided into endogenous and exogenous source according to the process control factors. The endogenous source includes: the level of materials safety, the level of adminicle use safety, the level of environmental hygiene management and the level of processing technology safety management.The exogenous source includes the level of national supervision, the level of consumer food safety consciousness and the level of agricultural product processing development. Every aspect includes various factors.

Base on the systematically geological investigation and study, we choose to use aremote sensing data source,the geography control data source(1:50,000relief map of Qiaojia and measured GPS ) as the data source of this research, adopt"Digital Landslide"processing image data, and carry on time-space analysiscombining geological investigation and related data. Application aerodynamicist theories, some important conclusions that obtained from the wind-tunnel experiment,and according to the time –space analysis result, we analyzed the landslide dammingmovement mechanism, presumed the movement format of this high-speed landslide,studied the formation mechanism and the movement characteristic of this landslide ,calculated it's movement equation, applied VC language to write calculationprocedure of each stage of the landslide, computed movement speed and displacement,and made sure its possible stop district.

本文在前人研究的基础上，选用遥感数据源、地理控制数据源(1：5万巧家幅地形图及实测GPS点)为本研究的数据源，采用"数字滑坡"技术处理图像数据，结合野外实地考察及相关资料对石膏地滑坡进行了时空分析；运用空气动力学理论，采用胡厚田等人在风洞实验中得出的许多重要结论，根据时空分析结果分析滑坡的运动机理，推测高速滑坡的运动模式；研究石膏地滑坡的形成机理、运动特征及运动方程，并用C++语言在VC开发环境中编写滑坡各阶段的计算程序，计算滑坡的流动速度及运动位移，确定其可能的停止区域。
