查询词典 time interval

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法，对这三种模型的基本原理、模型的构建过程进行对比分析，在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量，并对三种方法的特点、预测的准确度和适用范围进行了比较分析，结果表明：(1)马尔可夫链预测模型属于中长期预测，预测的结果为区间预测，但对于害鼠种群数量的预测来说已经达到要求，通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测，预测的结果都比较准确，这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态，马尔可夫链模型是比较好的模型。

Many schoolmates in study English time often only has used the eye, or uses the hand, to use the mouth, to use the ear, has used some organ, but had not thought that inside unit interval/unit time, may actually the five senses and uses, such words may enhance itself to study English the efficiency.how is that concrete does?

In a world where no one is compelled to work more than four hours a day, every person possessed of scientific curiosity will be able to indulge it, and every painter will be able to paint without starving, however excellent his pictures may be. Young writers will not be obliged to draw attention to themselves by sensational pot-boilers, with a view to acquiring the economic independence needed for monumental works, for which, when the time at last comes, they will have lost the taste and capacity. Men who, in their professional work, have become interested in some phase of economics or government, will be able to develop their ideas without the academic detachment that makes the work of university economists often seem lacking in reality. Medical men will have the time to learn about the progress of medicine, teachers will not be exasperatedly struggling to teach by routine methods things which they learnt in their youth, which may, in the interval, have been proved to be untrue.

在一个无人被迫每天工作4小时以上的世界，每一个怀有科学好奇心的人都可以全身心地投入；每一个画家都可以专心绘画而不致挨饿；年轻的作家们不必被迫以耸人听闻的粗制滥造作品来吸引注意力，以使自己有经济能力来写出不朽的作品，而时机一旦来临，他们或许已经丧失了情趣和能力；那些在业务工作中，滋生了经济学或政府工作某个方面兴趣的人，能够发展他们的思想，而不必受学术机构的羁绊，这种羁绊往往使大学里的经济学家的工作缺乏现实性；医务工作者们能有时间学习医学上的进展；教师们也不必再恼火地勉强用老掉牙的方法教授他们年轻时学过的东西，而这些东西时过境迁，可能早已不符合实际了。

Based on this idea, the author has chosen two typical loess sections of Luochuan, and Xifeng for this study, collected the successive loess columns; To probe the conditional experiments of BeO sample preparation and measurement, and improve the existing method; On the basis of the technology improvement, the author has finished 402 samples' BeO preparation and AMS measurement; Also at the same time, to separate quartz from samples at 1 cm interval for both Luochuan and Xifeng sections systematically, to carry out measurements of quartz grain-size, SUS, grey scale, carbonate content and bulk sample density; By using the grain size model, the author has set up the chronological framework for both Luochuan, and Xifeng sections and the time sequence of millennial scale abrupt climate events recorded in loess strata, and reconstructed the East Asian monsoon history over 130ka by using multi proxies; Finally, to discuss the possible mechanisms of palaeoclimatic changes tentatively.

详细地球科学的发展离不开高精度和高分辨率的研究。运用长寿命核素如〓Be作为环境过程的示踪，已成为不可替代的有效工具。本论文选择洛川、西峰两个典型的黄土剖面，连续采集柱状样；探索了BeO样品制备、测量的条件实验，改进了原有的方法，完成了402个BeO样品的制备和AMS测量；同时还系统地分离洛川、西峰剖面高分辨率（1cm）黄土、古土壤样品中的碎屑石英，测量了碎屑石英粒度，以及全样的磁化率、灰度、碳酸盐含量和容重等古气候代用指标；采用粒度年代模式建立了洛川剖面和西峰剖面的年代标尺，建立了黄土地层记录的千年尺度的气候突变事件的时间序列，多指标重建了最近130ka东亚季风变迁史；初步讨论了古气候变迁的可能机制。

The results showed that different topping frequency (at intervals of 15 d, 30 d, 60 d, 90 d) had no evident influence on total wine loss, volatile acid content, T-SO2,F-SO2, wine colour, and wine pH values. Under constant temperature and humidity conditions, total wine loss was closely correlated with the using degree of Chinese barrel and the storage time in Chinese barrel. Volatile acid content slightly rose along with wine storage time. The content of SO2 dropped rapidly during 15 d after wine filling, but dropped tardily ever since. Wine colority rose remarkably during 15 d after wine filling, but climbed tardily ever since. Wine colority change was unstable, it changed wavily and depressed on the whole. In conclusion, it was recommended that the best topping interval was 90 d.

结果表明，橡木桶15 d、30 d、60 d、90 d添桶间隔对红葡萄酒的酒液损失总量、挥发酸含量、T-SO2、F-SO2、颜色、pH值无显著影响；在恒温恒湿的条件下，红葡萄酒的酒液损失总量与橡木桶的新旧程度、桶贮时间密切相关；随桶贮时间延长，葡萄酒中挥发酸略有上升；葡萄酒入桶后15 d内SO2含量急剧下降，以后则缓慢下降；葡萄酒入桶后15 d内色度显著上升，但随后变化平缓，总的趋势是随桶贮时间延长色度缓慢上升；葡萄酒的色调变化不稳定，呈波浪式变化，总的趋势是降低；建议中国橡木桶桶贮红葡萄酒的添桶间隔为90 d。

Image reconstruction from the projections of fan-beam: The CT equipment is broadly adopted on the world that its detectors are arranged on the concentric circle at same angle interval. This equipment rebates the complex machinery movements like parallel-beam geometry, makes the sampling time shorter, that is rebating the whole CT testing time.

The association rules of the traditional data mining technique are used to mining higher appearance frequency and support for itemsets. If the association rules are applied to mining the outbreak symptom of excrescent disease, the support of partly outbreak symptom not high will be ridded during the mining process. The reason is that the number of excrescent disease patients is less than the number of ordinary patients. In addition, the outbreak symptom of excrescent disease may have the successively order of time happened, for example, symptom B will just take place sometime of interval later after symptom A. The data mining techniques that generally direct against the higher appearance frequency itemsets and only consider the single dimensional sequential pattern cannot totally search the pattern of outbreak symptom of excrescent disease, and cannot also provide related reference information to prescribe medicine for nursing staff at that time.

由於传统资料探勘技术中之关联规则是用来针对资料集合中出现频率较高亦是支持度高之项目集合进行探勘，若是应用於异常疾病发病徵状样式之探勘，由於异常疾病病患人数不及於普通疾病病患人数之缘故，因而造成部份发病徵状之支持度不高，将会在探勘过程中被去除，另外这类异常疾病之发病徵状可能会有先后发生时间之顺序，例如症状A发生后间隔一段时间后才会发生症状B，所以一般针对高频项目集合且只考虑到单一顺序维度之资料探勘技术，并无法完全找寻出这类异常疾病发病徵状之样式，也就无法在第一时间内提供医护人员对症下药之相关参考资讯。
