The revised Hargraves formula has the best result compared with Penman-Monteith formula, the average relative error is 6%, moreover, Hargaves method requiring the least data in calculating ETo, so this method has the high actual application value; The following are Radiation method and Blaney-Criddle method ; The worst is the Pan method, even after revised, the highest and average relative error is 36% and 10%, respectively. So, in this study, Penman-Monteith method, Radiation method, Blaney-Criddle method and Hargraves method are used except Pan method.

在这四种方法中，修正后的Hargraves方法与彭曼—蒙特斯方法的计算结果符合最好，其平均相对误差为6％，而Hargraves方法需要的气象数据只有计算时段的最高、最低温度，该方法具有较高的实际应用价值；辐射方法和布兰尼—克里德尔方法次之；蒸发皿方法最差，即使在修正后，E601型蒸发皿的最大误差也高达36％，平均为10％，所以在预报系统的研究设计中采用了除蒸发皿方法之外的四种方法。

Considering of different meteorologic data in different regions, five methods (namely Penman-Monteith method, Radiation method, Blaney-Criddle method, Pan method and Hargraves method ) of calculating reference Evapotranspiration proposed by FAO are used, and FAO Penman-Monteith method is taked as the criterion to revise other four methods, thus educing the revised formulae in studied region.

考虑到不同地区可用气象数据的不同，本研究中选择了联合国粮食与农业组织推荐的五种(FAO彭曼—蒙特斯方法、辐射方法、布兰尼—克里德尔方法、蒸发皿方法和Hargraves方法)计算参考作物蒸发蒸腾量的方法进行比较研究，并以公认的FAO彭曼—蒙特斯方法为标准，对其它四种方法进行修正，得出适合本论文研究区域的相应修正公式。

But scientists who have long studied Beijing's weather patterns say the blue skies have less to do with the city's $17 billion anti-pollution programs than with simple meteorology.

但是一些长期从事北京气象问题研究的科学家们说，城市170亿美元的反污染工程对于蓝天的影响甚微。

Hematocrit of 15,178 subjects in observation group and 150 healthy adults in control group were examined in different seasons from 1993 to 1997 for statistical analysis.

93～97年检测15，178例中、老年男、女性成人红细胞压积值，对其与多种气象要素作相关性分析。

In Iberia Volume IV, Albeniz used Spanish idioms as composing materials, such as flamenco dance rhythms and cante hondo. He also mixed French and German augmented sixths to create new sounds, which was so-called "Iberian sixth". In addition, he used guitar idioms into Iberia to make it full of unique sounds and also brought a new wave into Spanish music.

由本论文的探讨中得知，阿尔班尼士将西班牙民俗音乐的特色，像是佛朗明哥舞曲节奏及深沉歌谣风格加以运用，不断地开发特殊的音响效果及音乐语言，以及吉他语法融入作品中，并以自己独特的音乐语法，赋予作品更丰富的特性，为西班牙的音乐注入一股新气象。

Sir Brian Hoskins, director ofthe Grantham Institute for Climate Change at Imperial College Londonsaid the Met Office and WMO annoucements reconfirm the strong warmingtrend that scientists have observed over the last century.

伦敦帝国学院格兰瑟姆气候变化研究所所长布莱恩·霍斯金斯爵士说，英国气象局和世界气象组织的公告再次确认科学家们观察了一个世纪的强烈气候变暖趋势。

V is evaluated using the average value of 03 driest months in 03 consecutive years data of National Hydrography Meteorological Centre

The wide used method in weather, hydrography, etc., Kalman filter, is used to update the coefficients of the empirical model and expected to make better improvement. The test with the ionosound data of hourly values from 1986 to 1995 at Changchun illustrates that the root-mean-squre error of the forecasted values in one hour advance is 0.76 MHz in winter, 0.68 MHz in summer and 0.61 MHz in equinoxes, respectively.

尝试利用气象预报中常用的Kalman滤波方法对模型的系数进行实时修正，以提高预报精度，并对长春站1986-1995年近一个太阳周f0F2数据进行提前一小时预报试验。
