That's positively sedentary for private citizen Bill Clinton, who has yakked his way through nearly 200 speeches in 30 countries since leaving office 14 months ago, an average of almost one every other day, not counting all the times he holds court -- sometimes endlessly -- with practically anyone he meets.

In order to avoid the limitation of using only Tobin's Q to evaluate marketing performance and return on equity to evaluate financial performance, this paper introduces factor analysis to calculate synthesized performance, successfully processing totally 12 original indexes, such as return on net sales, average return on equity, return on total assets, per share earning ratio, current ratio, quick ratio, debt to assets ratio, rate of stock-turn, accounts receivable turnover, total asset turnover, main business growth rate, and total assets growth rate.

为了避免单纯使用托宾Q值度量企业市场业绩以及使用净资产收益率等单一财务指标度量企业财务业绩的缺陷，该文运用了因子分子法求得上市公司的综合绩效，成功地对总共12个原始绩效指标，如销售净利率、平均净资产收益率、总资产报酬率、每股收益、流动比率、速动比率、资产负债率、存货周转率、应收账款周转率、总资产周转率、主营业务收入增长率以及总资产增长率等进行了处理。

Results show that plant communities on the flat sandy land with impermeable stratum below root layer, in terms of average soil water content in different plots, ranke in the ascendant order of Leymus secalinus community (4.91%), Oxytropis aciphylla community (7.42%), Caragana korshinskii Community (10.36%), Artemisia ordosica Community (12.55%), and bare sandy land (16.27%). In the same plant community, soil water content is different in different seasons.

And the average WDI for every month was calculated from 60 decades WDI and the drought frequency for every month was obtained with a drought criterion. Results showed that: in spring, North-western China, Northern China and Southern China have a higher drought frequency; in May to August, the region that has a higher drought frequency focus on North-western China and Northern China; from September to December, North-western China, Northern China, center China and Sichuan basin has a higher drought frequency (6) The relationship between average WDI for all the 720 decades in 20 years and average precipitation was analysed and was used to regionalize drought in China.

5分析我国近20年干旱发生的时空分布特征：利用1982-2001年NOAAAVHRR8km数据集，计算了20年来我国各旬干旱空间分布，并根据一定的干旱发生判断标准，统计我国不同地区在各月相发生干旱的频率和各月份平均WDI，初步分析我国干旱发生的时空格局，结果表明：在春季，西北地区、华北平原和华南大部分地区的干旱发生频率都比较高；在5-8月份，高频率干旱发生地区就主要集中在西北和华北平原地区；9-12月份干旱发生高频率地区在主要在西北、华北、华中和四川盆地等地。

At the every relative momentary point of time time-space, is to the situation of observe identity mutuality gravitation and space-energy quantum spatial measurement cosmic energy at relatively determine, namely to the difference of quantity quantum of the original spatial measurement and the spatial measurement limit of cosmic energy, to the quantity of quantum spatial measurement cosmic energy, to the situation of spatial measurement and spatial curvature relative time-space cosmic energy, to the difference of spatial measurement of the gravitation exceed the space-energy of quantum spatial measurement cosmic energy, to the situation of the average density spatial energy and the temperature spatial background of relative time-space cosmic energy, to the situation of spatial measurement and spatial curvature relative vacuum cosmic energy all at relatively determine.

在时空时间的每一个相对时刻点，是对宇宙能量的宇称量子的引力与空间能的守恒状况的相对确定。即是对宇宙能量的原初宇称量子与极限宇称量子的数量差，宇宙能量的宇称量子数量，宇宙能量的相对时空的宇称及空间的曲率状况，宇宙能量的宇称量子的引力大于空间能的宇称差，宇宙能量的相对时空空间的能量平均密度及空间的背景温度状况，以及对宇宙能量的相对真空的宇称及空间的曲率状况全都在相对地确定。

Bifurcation behaviour of nonlinear systems under the resonance condition isstudied when there are parametric and external excitations at the same time.

本文提出的映射迭代法可以有效地用于强非线性系统的定性分析，且对于弱非线性系统，其一次近似的平均方程与其它方法等价。

A simulation is done between MAODV and AODV with software. From the simulation results under different node speed, it indicates that MAODV could decrease the average of ETE delay and offer lower routing overhead effectively. MAODV can complete routing discovery, package retransfer and self-organize when the network topology is changed, MAODV routing protocol is useful to establish Ad hoc networks in military communication.

应用软件对MAODV路由协议和传统的ADOV路由协议进行了仿真，通过在节点不同移动速度下的网络性能进行仿真比较，结果表明，MAODV路由协议能有效地减小分组端到端传输的平均时延，降低协议开销，能够根据网络的拓扑变化进行自组织，完成路由的发现和分组的中转等基本功能，为自组网在军用通信中的运用奠定了基础。

The mean velocity distributions in turbulent boundary layers of smooth surface and two different riblet surfaces are measured with IFA300 constant-temperature anemometer in low-speed wind tunnel to validate the full development of turbulent boundary laye. Friction velocity and wall friction stress of turbulent boundary layer are obtained with the least-squares fitted curve of the sublayer velocity distribution based on Spalding formula, and virtual origin position of riblet surface can be acquired accurately.

在低速风洞中来流速度一定的情况下使用IFA300恒温热线风速仪测量了光滑表面和两种不同尺寸的脊状表面湍流边界层平均速度分布剖面，并验证了试验段湍流发展的充分性；通过应用Spalding壁面公式使用最小二乘法精准拟合了实验测量的边界层内层速度分布曲线，得到了湍流边界层壁面摩擦速度并进一步求得湍流壁面摩擦应力，较准确地计算出脊状表面的虚拟原点位置，并通过与对数律公式拟合结果比较分析，证实了该方法更加准确有效。

The XXZ model with the longitudinal magnetic field can be exactly solved by the Bethe ansatz method, but the similar rigorous solution has not been found in the case with transverse field.

尽管如此，通过Jordan-Wigner 变换，用一种修改了的平均场近似方法，我们可以较为准确地描述这一系统的整个基态相图。

The European position is feeble but not risible, for it has offered an overall average cut in its farm tariffs of 39%, up from 25% only a month ago, though with rather a lot of loopholes that could severely limit the benefits.

欧洲的立场是无力的，而不是滑稽的，因为它已经答应将其农产品关税平均削减39%，而一个月前，只答应削减25%，尽管有很多漏洞可能严重地限制这些收益。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
