The rise in temperatures during daytime was reduced but this is more or less offset by the heat generated from air conditioning and other urban activities . the net result is little change in the daily maximum temperature . overall , the annual mean temperature rises but at a slower rate than the annual mean minimum temperature 综合最高和最低气温的变化，日平均温度有上升的趋势，但速度较日最低气温慢。杨继兴说：换句话说，日间酷热的情?并未有恶化，但寒冷的夜晚却少了。
The results showed the drought index could successively and dynamically monitor the drought process , so it was the better representative ; the frequency of spring drought of the loess plateau area in gansu was stronger in north than in south and its center is in gansu center ; the frequency of serious late spring drought was increasing while that of early spring drought was decreasing 结果表明： ( 1 )干旱指数能够连续动态地监测干旱过程，因而具有较好的代表性； ( 2 )甘肃黄土高原地区早春旱和晚春旱北部高于南部，干旱中心在陇中； ( 3 )重晚（早）春旱的发生频率增加（减少） ，站数增多（减少） ； ( 4 )区域性早春旱随年代呈下降趋势，区域性晚春旱略有上升的趋势，但不明显。
N view of an increasing number of accidents relating to bulky luggage being carried on board train compartments and into escalators at stations , the kowloon - canton railway corporation ( kcrc ) today ( 2 april ) revised its luggage regulations that control the number , size and weight of luggage items that can be carried into the east rail 鉴于乘客因携带大型行李导致意外而受伤的个案有上升的趋势，九广东铁今日（四月二日）开始，限制乘客随身携带大型行李的数目、体积和重量。

Soil saturated capacity , capillary capacity , total porosity and capillary porosity showed the trend of the " u " during the successional course of artificial forest , namely , they reduced on the early successional stages , after picea reached mature forest , soil porosity recovered slowly . the content of natural water was mainly affected by capillary porosity . from soil chemical properties analysis , the content of soil organic , humus , ha , fa and ha / fa of topsoil was more than that of bottom layer 即人工云杉幼林向成熟林演替阶段，土壤饱和持水量、毛管持水量及总孔隙和毛管孔隙则减少，在40年生云杉林达最低值，之后随着云杉自疏，微生态改善，林地凋落物分解加快，土壤饱和持水量、毛管持水量及总孔隙和毛管孔有上升的趋势，毛管持水量是决定林地自然含水量的主要因子。
