查询词典 period

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。

XiangHe developing zone is variable zone continent climate, four clearly seasons, the winter heating period is from 15th Nov to next 15th Mar, lasts about four months, it's a long period.

香河经济技术开发区属温带大陆性季风气候，四季分明，冬季取暖时间为11月15日至三月15日，达四月之久，供暖周期较长。

The poly-choral style originated from Venetian school in the 16th century is an important style of development of instrumental music which has affected the Baroque period and the period after Baroque.

摘要 源自十六世纪威尼斯乐派的复合唱风格，是影响了巴罗克时期，及其之后器乐曲发展的重要风格之一。

The main focus of this paper is the discourses of 'vernacularism' and the invention of 'native Taiwaneseness' constructed and imposed by the Japanese during the colonial period, which is followed by my analysis of its transformation and continuity into the postcolonial period.

本文主要重点为「本土主义」论述与在日本殖民时期由日本人所创造与命名的「本土台湾人」概念，接著进行笔者对此论述进入后殖民时期之转型与延续的分析。

The present paper falls within the scope of three historical phases, Japanese Colonial Period, Post-hostilities Period and contemporary relevance; it takes diachronic Luan-tan Opera audio materials in the same play for the research theme, cuts into the angle with vernacularism, attempts to observe the varieties of language changing while these troupes were trying to fit in the environment.

本论文以日治、战后及当代三个历史段落为范围，选择跨越两个时空以上、相同剧目的乱弹戏有声资料为研究题材，并以戏曲剧种的白字化为切入视角，试图观照戏曲剧种适应环境所因应的变异性，即「剧种语言」在地化的现象。

Through concretely analyzing the magnitude and error of deflection of the vertical, we can get the results that the long-period, smaller-range non-tidal variations are commonly less than the tidal ones, but the short-period, larger-range non-tidal variations are comparable to the tidal ones, especially in some areas they are even bigger than the tidal ones, this state can be measured by repeated gravimetry completely.

通过对垂线偏差量级和误差大小的具体分析，得出结论：一般长周期的、幅度较小的非潮汐变化要小于潮汐变化，但短周期的、幅度较大的非潮汐变化则可能与潮汐变化相当，个别地区甚至还会超过潮汐变化，这种情况完全可以用重复重力测量的方法检测到，这也说明重复测量的方法是可行的。
