求翻译：本文通过调查德州市人民医院1999年1月至2008年12月高血压住院病例，并与同期德州市国家气象观测站逐日气象资料进行分析研究，试图为德州市医疗气象预报提供依据。为排除非气象因素的影响，对资料进行了适当处理，对发病日进行等级划分，运用单相关分析四季高血压发病等级与同期气象要素及其变化的关系。研究发现：春秋季强冷暖空气活动，均会造成高血压发病，冬季主要是强冷空气活动造成。高血压发病等级：春秋冬季与气温、气温距平、气温变化反相关；夏季与气温正相关，与气压反相关；春季与气压变化的绝对值正相关，秋季与气压、气压变化及其绝对值、气压距平及其绝对值均为正相关；冬季与气压、气压距平、气压变化正相关。秋冬季连续阴天寡照、秋季出现降雨、冬季出现大雾，高血压发病等级增高。是什么意思？

This paper surveys inpatients with hypertension in dezhou city people's hospital between January 1999 and over the same period and analysis of the national daily meteorological data meteorological station in dezhou city and dezhou attempted to provide a basis for medical meteorological forecasting. To exclude non-effects of weather factors, the information has been dealt with adequately, on the date of onset for grading, using single correlation analysis of hypertension grade in four seasons and the relationship between meteorological elements and changes over the same period. Study finds strong spring and autumn cold and warm air activities are causing hypertension, mainly strong cold air in winter activities. Hypertension grade: spring and autumn and winter and the temperature, air temperature anomalies, variation against temperature related; and summer temperatures are related, and anti-related pressure; and the absolute value of pressure in the spring, autumn and changes in air pressure, air pressure and its absolute value, a positive pressure anomaly and its absolute value is related; in winter and air pressure, air pressure anomalies, pressure changes are related. Continuous cloudy oligo shines in autumn and winter, rainfall occurs in autumn and winter appears dense fog, hypertension grade increases.
