Slide a book across a table and watch it slide to a rest position. The book in motion on the table top does not come to a rest position because of the absence of a force; rather it is the presence of a force - that force being the force of friction - which brings the book to a rest position.

The P.pratensis community is in the phase of herbs and forbs of degraded alpine meadow.At the same time the P.pratensis population is in the dominant spices position,subordinate spices position and company spices position.So,we can replant P.pratensis and other grass seed to change the structure and composition of plant community,improve community environment,cause it to develop to subclimax community succession,reach the stabler state.We can apply fertilizer,improve soil nutrition condition,enable degraded grassland with the link of soil and vegetation system together to reach the stabler subclimax and climax state.

草地早熟禾群落处于高寒草甸退化的禾草杂类草阶段，草地早熟禾种群在群落中处于优势种地位、次优势种地位和伴生种地位，因此，可通过补播草地早熟禾和其他禾草草种，改变植物群落结构和组成，改善群落环境，使其向亚顶级群落演替，达到较稳定的状态；也可通过撒施肥料，改善土壤养分状况，使土壤与植被系统共同作用将退化草地演替为较稳定的亚顶级或顶级状态。

The analysis of SAR reveals that the activities of target compounds are closely associated with the electron-withdrawing substituents at the para position of 1-aryl-1, 2, 4 -triazoles as well as with the substituents such as sulfonyl and methylthio groups at the 3 position of 1, 2, 4 -triazoles; And the introduction of sulfamoyl moiety at the para position of 5-aryl-1,2,4-triazoles also has significant influence on the anti-inflammatory activity of these compounds.

构效关系分析发现，在三唑环1位芳基的对位引入F、Cl、Br吸电子基团以及3位引入磺酰基和甲硫基，对抗炎活性有重要的意义；在三唑环5位芳基的对位引入氨磺酰基，对抗炎活性有较大影响。

Cinnabarinus at 150 mg/L.The influences on bioactivity of substituted pyrazole and pyrimidine were discussed respectively: pyrazoles substituted with phenyls at 3 position had higher activity than thiophen and compounds with R_1=methyl had higher activity than that with R_1= hydrogen, pyrimidines substituted with methyl at 2 (R_3) and 5 (R_3) position and phenyl at 6 position were most active.

本论文对吡唑及嘧啶取代基对活性的影响分别进行了讨论，可知：吡唑3位为取代苯基的化合物杀菌活性优于取代噻吩的，吡唑4位(R_1)为甲基的杀菌活性高于R_1为氢的活性；嘧啶的2位(R_3)为甲基，5位(R_1)为甲基，6位为无取代基的苯基时活性最好。

125E The final phase in a bull move is an accelerated runaway near the topE In this phase, the market always makes you believe that you have underestimated the potential bull marketE The temptation to continue pyramiding your position is strong as profits have now swelled to the point that you believe your account can stand any setbackE It is imperative at this juncture to take profits on your pyramids and reduce the position back to base levelsE The base position is then liquidated when it becomes apparent that the move has endedE

一个牛市运动的最后阶段是一场接近顶部的加速赛跑。在这一阶段，市场总是让你相信你低估了潜在的牛市。随著盈利膨胀到让你相信你的账户可以对付任何挫折，继续堆砌你的头寸金字塔的诱惑强大。在这关键的时候，要紧的是从你的金字塔上拿走你的盈利，把你的头寸减少到基本水平。随后，当这一运动变得显然结束了时，将这基本头寸也平仓。

Second, we point out that the AAM model contains redundant information between the shape and the texture on the basis of the study of AAM model. We remove the unsoundness, directly establish the relationship between the shape and texture, use texture to determine the shape, then establish PCA model of the difference image, and use this model to predict the next position to get the texture information form this position, and redetermine the shape and its position.

其次，在深入研究AAM模型的基础上，本文指出了AAM模型的形象模型包含了冗余信息，并对此进行改进，直接在形状和灰度之间建立起联系，由灰度确定形状，然后再对差分图象建立起PCA模型，由此模型预测下一步的位置变化，在从此位置上获得灰度信息，重新确定形状及其位置。

First, context position is weighted by information gain; second, the position weight function is constructed according to weight of context position...

该文的结果对上下文在自然语言处理中的价值和作用给出了一个具有统计意义的量化解释

When the strap is positioned at the contracted position, the hook can be positioned adjustably along the length of the strap; when the strap is positioned at the spread position, the hook can be fixed on the selected position of the strap.

当带子处在收缩位置时，该钩子可调节地沿带子的长度定位；而当带子处在展开位置时，该钩子可固定到带子的选定位置上。

We hope that the formation of biazulene compound(201), under the coupling reaction of 1、3-position being along with electron-withdrawing group, 2-position being along with hydroxy group, and four 4、8-position being along with static energy obstacle large enough functional group of azulene compound(200), may have the chiral auxiliary effect like that of the BINOL.

希望将两个在1、3-位置上有拉电子基、2-位置上有羟基及在4、8-位置上有立体能障够大的官能基之薁类化合物(200)，进行偶合反应后所形成的双薁类化合物(201)能够像BINOL那样具有掌性辅助剂之效果。

In addition, error resource existing in rotor position estimation algorithm is analyzed comprehensibly, therefore, some further work is made to eliminate the negative influence from errors. In this research, additional function is added to rotor position estimation algorithm to enhance precision of position estimation and its feasibility has been proved.

根据已有的无位置传感器转子位置检测原理，提出了两种改进的检测方法：一是改进电感法的检测方法，并设计了检测电路；二是根据SR电机的ψ-I-θ关系，研究了基于模糊推理规则的间接转子位置估算方法，分析了估算过程中存在的误差源，研究了提高估算精度的策略。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
