But the vegetations changes in plain zone were slower.(4) Study on the driving forces and driving mechanism of the change of vegetation cover in HHH zone The farmland vegetation area received the common drive of climate and the society factors, but climate factors were the main driving forces for annual harvest crop or biannual irrigated and dry harvest crop, and society factors were the main driving forces for biannual harvest crop or biyearly tri-harvest dry crop.

4黄淮海地区植被覆盖变化驱动力与驱动机制研究不同植被覆盖类型，其NDVI变化的驱动力不同：一年一熟粮作区植被覆盖变化受到气候和社会经济因子的共同驱动，但以气候驱动为主；一年两熟或两年三熟旱作区植被覆盖变化受到社会经济和气候因子的共同驱动，但在主要驱动因子中，社会经济的影响更大一些；一年水旱两熟粮作植被覆盖变化主要受气候因子驱动，同时，社会经济因子也会在一定程度上影响植被NDVI的变化。

The Armed Forces Expeditionary Medal may be awarded to members of the Armed Forces of the United States who after 1 July 1958 participate as members of US military units in a US military operation in which service members of any Military Department participate, in the opinion of the Joint Chiefs of Staff, in significant numbers and encounter during such participation foreign armed opposition, or are otherwise place in such a position that in the opinion of the JCS, hostile action by foreign armed forces was imminent even though it does not materialize.

武装部队远征可授予勋章，以对美国武装部队的成员谁7月1日后1958年，美国的军事单位的成员参加美国的军事行动中的任何军事部门服务的成员参加，在意见参谋长联席会议，在大量的这种参与中遇到的外国武装反对派，或因其他原因有这样的情况发生，在参联会，外国军队的敌对行动迫在眉睫的意见是，即使没有实现。

Traditional air interdiction--again according to JCS Pub 1--is defined as "air operations conducted to destroy, neutralize, or delay the enemy's military potential before it can be brought to bear effectively against friendly forces at such distance from friendly forces that detailed integration of each air mission with the fire and movement of friendly forces is not required."

传统的空中遮断——也是依据参谋长联席会议的一号文件——被定义为"在敌方军事势力能够对友军带来打击效果之前的一定距离上实施摧毁，压制，或者是迟滞的空中行动，对于各项空中任务，不要求对友军的射击和移动进行逐一的综合识别。"

"It examines what happened and why, and it balances the traditional focus on international relations with an emphasis on the intricate web of internal affairs and events, for although external forces precipitated the demise of the Lamaist State, internal forces created the conditions under which these external forces could prevail."

应译为："本书所考察研究的问题是，这个喇嘛王国衰亡的过程及其原因，用强调错综复杂的内部事务和事件来平衡传统上将注意力只集中在国际关系上的方法，因为外来势力的介入虽加速了这个喇嘛王国的衰亡，然而其内部力量为外来势力在西藏得势创造了条件。"

The linear aerodynamic forces of airship hull were calculated in terms of Munk airship theory. The linear aerodynamic forces of airship hull were calculated by Allen viscous cross flow theory. The fins linear aerodynamic forces were calculated by approach of panel method.

根据势流理论对飞艇艇身线性气动力进行分析计算，由于飞艇艇体是旋成体，故根据Allen的横流阻力理论对其所受的非线性气动力进行计算；尾翼的线性气动力采用有限基本解方法进行计算，非线性气动力用Polhamus-Lamar吸力比拟方法估算。

The unbalance forces due to the lumped eccentric mass are treated as general forces. Meanwhile, the potential energy expression about gravity based on finite element method is presented for convenience. Based on the variational inequalities principle, the finite element is used to determine the film forces produced by fluid film bearing and damper at any moment and its Jacobian matrix with respect to location and velocity of journal and bearing house.

在第二部分中，主要应用有限元方法及Hamilton原理对所研究系统进行了建模分析，着重对质量偏心问题进行了分析处理，并对此提出了两种处理方法：一、转化为对系统动能的影响；二、将其产生的离心惯性力视为非保守的广义力，并对其表达式进行了推导，同时为分析问题方便，基于有限元离散化方法，推导了重力的势能表达式。

These eigenvalue algorithms are examined under the mode error, i.e, the ratio of out-of-balance nodal point forces that is the difference of maximum elastic nodal point forces and maximum inertia nodal point forces, and the maximum elast...

与ANSYS的子空间迭代和Lanczos法相比，本文的子空间迭代比ANSYS的效率高很多，Lanczos法和ANSYS的效率差不多。大量较大规模的例题显示，本文对特征值算法的改进是十分有效的，算法的健壮性，通用性都达到了高水平。

The main results can beexpressed as follows:(1)Based on πtheory, some affected factors about wave forces are given, and therelation between affected factors and wave forces is analysised by experimentalresults.(2) The distribution of wave press at representative time and reflection nature aregiven and their variety charactes are discussed by experimental results.(3)By comparing the wave forces of quarter-circular breakwater and semi-circularbreakwater under the same wave conditions,some approximately wave forcesexpressions of quarter-circular breakwater are given.(4)Based on VOF method to trace water free surface,solve numerical value ofRANS equation,and get the distributions of flow field and wave press ofquarter-circular breakwater at the same time during one period,the mechanism ofwave force is also discussed elementarily.(5) Based on the result that RANS equation of numerical simulation agree wellwith experimental results,a new approach to study hydraulic natures of quarter-circular breakwater is provided.
