The Japanese movie“0.5mm”connects the life clips between the nursing-care helper Sawa and several old people in the form of a road movie,highlighting many thought-provoking social problems,and revealing how the elements of emotional abuse hidden between the old people and their relatives and friends affect people’s dignity and decency,and at the same time trying to offset the persecution from the emotional abuse with the warm kindness between the elderly and the care *** film’s implicit description of emotional abuse and explicit display of good deeds are blended in the quiet and mysterious narrative character,achieving the effect of synchronizing the artistic narrative rhythm with the flow of life,reflecting the unique aesthetic characteristics of Japanese films.

由于青藏高原生态系统的脆弱性和对人类活动的敏感性,近年来高原环境中与人类活动相关的重金属污染研究受到越来越多的关注.本文通过2021~2022年间采集的青藏高原表土样品,结合同时期采集的周边高海拔冰川区雪冰样品,分析测定了As、Cr、Co、Ni、Cu、Mo、Cd、Pb和Sb共9种重金属元素的含量和组成特征.结果表明,青藏高原表土中重金属的含量(均值为256.5μg/g)远高于雪冰中重金属(均值为14.6μg/L)的含量.其中As的I geo平均值为1.32,总体处于中度污染水平,而土壤中其他重金属以无污染特征为主.表土中重金属的组成和空间分布与周边冰川区雪冰中表现出明显不同特征,而且不同区域表土重金属的空间分布、组成和富集系数(EFs)没有明显差别.结合相关性、主成分分析和APCS-MLR等方法,发现表土中重金属有3个主要来源,分别为居民生活和工业用煤有关的煤燃烧源(42.3%)、局地地表自生土壤来源(20.6%)和交通排放源(14.2%).高海拔雪冰和表土中重金属的组成、分布存在差异,可能是由于地表样品中重金属受到自然风化、和人类活动影响导致远距离输入源的贡献被掩盖,而雪冰中重金属则更多受到大气环流远距离输入污染源的影响.本研究较为全面的展示了目前青藏高原大范围区域表土中重金属组成状况,反映出部分元素的明显富集(例如As)和整体上重金属元素含量仍然表现为清洁的自然状况.

In China, meteorological forecasting relies on meteorological data obtained from regional and national stations. However, there were discrepancies between the data collected from the meteorological station at the passion fruit growing base and the data from regional and national stations. Consequently, the high and low temperature disaster indicators determined by the meteorological station at the passion fruit growing base cannot be applied to meteorological forecasting. To address this issue and facilitate the monitoring and early warning of high and low temperature disasters in passion fruit cultivation in Fujian, China, we used multi-source hourly temperature data (including the data from meteorological observation stations in passion fruit growing bases, the nearest regional stations, and national surface conventional meteorological observation stations) in three cities in southwestern Fujian (Longyan, Sanming, and Zhangzhou) spanning the years 2020 to 2022. By employing comprehensive statistical analysis methods (0.5 interval division and Cumulative frequency), we identified that passion fruit in southwestern Fujian was susceptible to high temperature disasters during the blooming-fruiting period, as well as low temperature disasters during the sprouting period. Consequently, we developed high and low temperature disaster indicators based on data from regional and national stations for different phenological periods of passion fruit in this region.
