Experimental Study of Yearly Change of Soil Water Infiltration Characteristics

土壤水分入渗年变化特性的试验研究

However, the anomalies of moderately strong earthquake ′ s field precursors are short-term, negative ones with obvious amplitude, and show pulse bound, high value rising within short time, step-like change, and the regularity of yearly variation is broken.

而中强震场兆异常，一般表现为幅度明显的短期内的负异常、脉冲突跳、短期内的高值上升、阶变及年变化规律被打破等；

Through detailed analysis on climate change in the period of 1981 ￣ 1994 in Hubei Province, it was found that the yearly mean temperature in this province was getting lower gradually which was different from the results of study on the globe and other palces of China.

对80年代以来湖北省气候变化进行了详细分析，发现该省年平均气温变化是以降温为主，这与全球、全国的一些研究结论不同。

Analyses in the yearly, seasonal change of and regional differences on Korean wind speed and sunshine.

韩国的风速和日照时数的年 、 各季变化趋势和年际变化、地域性分析.

, yearly average temperature classification, gradually analyze the Chinese farm land dynamic change in the differ background.

第二，基于中国高程分级、坡度分级、降雨量分级、干燥度分级和年均温分级，逐一分析了不同自然环境背景下的中国耕地动态变化。
