exhaust gas recirculation

According to a lot of measured data and by the statistical method of fuzzy grade and the statistical method of isodensity graph put forward presently, two conclusions are reached as follows: (1)natural calamities often occur nearby solar terms; (2)natural calamities often occur nearby golden section day between solar terms.

根据大量的实测数据 ,利用模糊分级统计法和新提出的等密图统计法 ,经分析得到两点认识 :( 1)自然灾害多数出现在节气日附近 ;( 2 )自然灾害多数出现在节气之间的黄金分割日附近。

Base on the cases of upper digestive tract bleeding from 2000 to 2006 and the solar terms they belong to as well as the meteorological data,the relationship between the climate change and the UGB is analyzed.

通过对2000~2005年龙岩市第一医院上消化道出血(UGB)患者入院时的节气归属及当时气象资料的收集,分析不同节气气候变化与UGB的关系,运用最优子集回归方法建立关系模式进行综合分析,得出影响上消化道出血发病趋势的关键气象要素是节气最高气温、最低气温、平均水汽压;通过节气气候因素对UGB影响的认识,提出相应的预防保健措施。

They also delimit the 24 solar terms,years,months,days and hours.

立竿测影、日晷是追随“天极”、“二十八宿”的框架 ,来测定天地东西南北中这五个方位 ,并据此划分 2 4节气、岁、月、日、时 ,这些内容是对地球全方位直面太阳运动的演示。
