Aiming at the uniform features of acceleration response spectra, two scalar periods-the response spectral predominant period T and the smoothed spectral predominant period T are employed to normalize the abscissa of the normalized response spectra of ground motions, respectively.

为了考察地震动加速度反应谱的统一性，用2种标定周期（反应谱卓越周期T和平滑化反应谱卓越周期T）分别对传统规准反应谱的横坐标进行规准化。

"But if the economy does well over a long period, markets will do well over a long period," he said. In the short run, the market's a voting machine and sometimes people vote very unintelligently. In the long run, it's a weighing machine and the weight of business and how it does is what affects values over time.

假如经济长期表现得很好，市场也会有一样的表现，短期而言，市场是一台投票机器，而且有时人们投票时非常不明智，但是长期而言，市场是一台体重计，用来测量企业的重量有多少，以及长期影响企业价值的是什么。

The closing of any purchase occurring under this Agreement shall occur no later than thirty (30) days after expiration of the time period specified in subparagraph above for a party to obtain financing to purchase the Stock, or in the case of a purchase by the Offeror pursuant to the second unnumbered paragraph of above, within thirty (30) days after expiration of the time period for the Offeree's election whether to purchase the Offeror's Stock.

截止发生任何购买本协议项下应在不迟于期满后30天的时间内指定项以上的一方获得资金购买股票，如果是购买要约根据第二个未编号的段落以上，后30天内到期的时限要约的选举是否购买要约的股票。

For the model with exponent input, the endemic equilibrium is locally asymptotically stable when the period of latency is small enough; the endemic equilibrium is unstable when the period of latency is large enough.

对于带有指数输入的情形，发现地方病平衡点当潜伏期充分小时是局部渐近稳定的，当潜伏期充分大时是不稳定的。

Because the additional reference signal is not necessary, the delayed time is not related to the period of UPO and should not be the integral multiple of the period of UPO, so the presented method is simple and easy to apply.

由于不需要外加参考信号，延迟时间与UPO的周期无关，不必是UPO周期的整数倍，所以该方法简单易行。转载于中国论文联盟 http：//www.lwlm.com

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.

由于各区域之间土壤、气候条件的差异，各地土壤水分循环4个阶段的划分也不尽相同；黄河流域不同旱作类型区土壤水分动态变化比较结果表明：就季节变化而言(来源：A70b0B0bC论文网www.abclunwen.com)，由半干旱偏旱区→半干旱区→半湿润偏旱区→半湿润区土壤水分含量呈逐渐增加的变化趋势，而且高值区一般出现在雨季恢复阶段或春季土壤融冻返浆时期；而低值区均出现在春季大量蒸发阶段或秋季缓慢蒸发阶段；就垂直变化而言，黄河流域不同旱作类型区土壤水分垂直变化的趋势均表现为上层变化幅度较下层大。

The wavelet variance verification also indicates that the first main period of the runoff of mountainous watershed in the Shiyang River Basin is 30years, and 22years and l5years are the second and third period respectively; 3 Then we also compared the total runoff of mountain watershed with climate factors of Wushaoling which station is in the mountain headstream area, such as precipitation and temperature, the data record that the correlation coefficient of annual runoff and precipitation variation over the upper reaches in the Shiyang River Basin is 0.61 ,which indicates precipitation is the main water recharge of the runoff.

石羊河流域出山口年径流的周期变化与乌鞘岭站年降水量和年均气温周期基本上都能在同一周期上下浮动，其中出山口年径流量与乌鞘岭山区年降水量相关系数为0.61，说明地表径流量主要是由山区降水补给；年径流量与山区年均气温变化呈0.28的反相关，说明该流域近50年来出山口径流与山区气温呈反比，即径流量随年均气温上升而减少，相关性暂时不十分明显。

On the basis of determining their resistant spectrum, CY21, CY23, CY27, CY29, CY30, CY31, CY32, Su-11, Su-14 were used to investigate the resistant components at seeding stage, such as latent period, infection efficiency, uredinium length, sporulation capacity, period of spore production and severity. Also, two equal weight races' mixture CY27:CY30, CY27:CY31, CY27:CY32, CY31:Su-4, CY30:Su-11 were continued to reproduce six generations of Libellula and Xiannong 4 respectively, and the ration changes of each race were tested.

在抗性谱测定的基础上，采用CY21、CY23、CY27、CY29、CY30、CY31、CY32、Su-11、Su-14等9个条锈菌菌系，分别测定其苗期潜育期、侵染频率、夏孢子堆长度、产孢强度、产孢期以及严重度，同时将CY27：CY30、CY27：CY31、CY27：CY32、CY31：Su-4、CY30：Su-11等5个等量混合菌系组合分别在里勃留拉和咸农4号上继代培养6代，测定各小种在组合中的比例变化。
