冬奥主题纪录片《粉雪奇遇》叙事策略与全球想象

冬奥主题纪录片是我国以全球性议题为契机讲好中国故事、传播“人类命运共同体”理念的关键文本。本文以中法合拍纪录片《粉雪奇遇》为个案,考察其融通体育、生态和文化的选题创意,分析其叙事视角、结构和内容维度的机制,阐释粉雪联结的风物意蕴,以期为在全球性议题中构建“中国叙事”提供借鉴和启示。

北海道的粉雪诱惑

有人说，想真正了解北海道，一生至少要去四次，因为每个季节的北海道都各有特色。不知道这么说是不是有点夸张，反正我选择在冬季去北海道，只是为了体验一下冰天雪地和洁白无瑕的粉雪。所谓粉雪，就是雪中几乎不含水分，更加固态。这些雪更加柔软，像棉花糖那样非常蓬松，让人即使跌倒，也不会感觉太疼。

两种面粉粉质曲线描述与比较分析

描述与比较了两种不同产地、不同品牌面粉的粉质特征,主要包括面团的形成时间、稳定时间、粉质指数等参数。结果表明,两种面粉的粉质参数都符合国家标准。统计分析,面团的形成时间和断裂时间存在显著的差异,但吸水率、稳定时间、粉质指数、弱化度差异并不显著。

Effects of Bacillus amyloliquefaciens Biofertilizer on Brassica juncea var. multiceps Growth and N_2O Emission from Soil

In this study, Bacil us amyloliquefaciens A3 was continual y incubated in shake fIasks contalning wastewater from sweet potato starch production as an ef-fective biofertiIizer for cuItivation of Brassica juncea var. multiceps（XueIihong）. Based on pot experiments in the greenhouse, the effects of chemical fertiIizers （CN）, biofertiIizer （BF）, inactivated broth （BI）, starch wastewater （SW） and the combination of biofertiIizer and chemical fertiIizer （BC） on the yield, NO3- content and NO2- con-tent of XueIihong, soiI physicochemical properties and N2O emission were investi-gated. The resuIts showed that the yield of XueIihong in BC and CN treatments was improved by five times compared with CK; BF and SW treatments had insignifi-cant impact on the yield of XueIihong. Compared with CN treatment, BCL treatment exhibited simiIar improving effects on the yield of XueIihong, in which NO3- content of XueIihong and soiI was reduced by 16.4%-73.6% and 22%-29%, which reduced the risk of nitrogen eIuviations in soiI; average N2O fIux （FPV30） in BCL treatment was reduced by 58.3%-73.1% compared with CN treatment. In concIusion, B. amy-loliquefaciens is a feasibIe Iow-cost biofertiIizer for sustalnabIe vegetabIe farming with a great potential for starch wastewater utiIization.

美在人间的《秋草雪鸪粉画集》

《秋草雪鸪粉画集》即著名美术家陈秋草、方雪鸪的粉画画集,这本画集是我国出版的第一本粉画画集。学界一致认为此画集已毁于日军炮火中,没有正式出版,现根据正式出版的此画集原版,详述了画集的具体内容,指出《秋草雪鸪粉画集》的重新发现有助于我们认识和了解粉画在我国早期发展的真实面貌,对于研究白鹅画会及中国早期洋画运动有着重要的参考价值,同时,对当下的绘画创作应该也有一定的借鉴和启示意义。

归途

放学了。 那时大雪依旧不停地落着。这场雪从夜里就开始了,早上地面已是白雪一片,但整个上午一直都没有停歇。从窗子里望出去,大朵大朵的雪花正漫天飞舞,飘然而下。雪花在空中簇拥着翻飞的样子似乎很有点急切欢乐的意思。操场里先前有一些同学在那里踏雪,抛打雪球,现在他们的身影连同嬉笑吵闹声都消失湮灭了。在城外远处。
