Recently, neural models have been proposed for headline generation by learning to map documents to headlines with recurrent neural network. In this work, we give a detailed introduction and comparison of existing work and recent improvements in neural headline generation, with particular attention on how encoders, decoders and neural model training strategies alter the overall performance of the headline generation system. Furthermore, we perform quantitative analysis of most existing neural headline generation systems and summarize several key factors that impact the performance of headline generation systems. Meanwhile, we carry on detailed error analysis to typical neural headline generation systems in order to gain more comprehension. Our results and conclusions are hoped to benefit future research studies.

对许多西方读者而言,小泉八云于年出版的《怪谈》经常被视为日本怪谈文学的重要文本。不过,此书原先以英文撰写并针对西方读者的事实,显示出在西方语境中作为一种文类的"怪谈"具有某种跨文化与翻译的特质,正因《怪谈》不仅仅是一本翻译作品,同时也是西方语境中怪谈文学源起的标记性著作,怪谈文类的起源因此可以是翻译研究上的有趣议题。本文企图呈现这种双重书写(double inscription)的逻辑,并依此逻辑展开对于怪谈故事中"起源"概念的分析。本文首先探讨小泉八云在该书序里描述各种关于怪谈源起的方式,其次分析书中名作《雪女》自我否定/再生产的故事结构,来解释"起源"的概念不仅仅是重复叙述/翻译所产生的效应,同时也是叙事结构本身对于故事起源的认定与扬弃的双重需求所致。

This study assesses the level of contamination of Hg in farmland soils along the irrigating channel down-stream from Guizhou Organic Chemical Factory (GOCF),where metallic mercury is used as a catalyst to produce acetic acid. The total input of mercury into the environment,as announced by GOCF,is 140 t in the past 30 years (1971-2000). Sampling sites were chosen based on the distance from the source of pollution—the chemical factory. A total of 39 samples were collected from the study area and analyzed for total mercury concentrations and methyl mercury concentrations. The characteristics of vertical and horizontal distributions of total mercury and methyl mer-cury in the study area (farmland) are described in this paper. Much attention was paid to the transformation of inor-ganic Hg into organic mercury species in soils as well. The results showed that the farmland has been heavily con-taminated by Hg. Land cultivation activity,land utilization style and distance from the pollution source could be the dominant factors controlling the distribution of THg and MeHg. It is observed that active transformation of inorganic Hg into organic mercury species (MeHg) usually takes place in paddy soils.

为筛选出适合杉木优良无性系洋-061容器苗生长的轻型基质配方。采用单纯形-重心混料试验设计,以泥炭土、珍珠岩、杉木皮和稻谷壳为材料,并以黄心土为对照(CK),研究不同轻型基质配比对杉木生长、根系形态和养分积累的影响。结果表明,1)不同轻基质配方(T1-T14)和对照(CK)处理的苗高、地径和生物量均表现出相同的生长规律,即随时间增加而逐渐增大。2)当苗木培育360 d时,不同轻型基质处理苗高、地径和苗木质量指数均高于CK,其中,苗高在T6处理最大,较CK增加了54.89%,地径和苗木质量指数在T6和T1处理时达到最大,分别较CK提高33.04%和48.65%,T14处理下生物量最大;3)不同轻型基质处理有效促进了杉木幼苗根系的发育,而且其总根长、根表面积、根直径及根体积分别在T2、T14、T9和T14处理时达到最大;4)杉木植株养分含量对不同轻型基质响应存在差异,其中轻型基质T5、T3和T12处理显著促进植株氮的积累,轻型基质T8、T3和T13处理苗木全磷含量显著高于其他处理,而T8、T9和T2植株全钾含量显著高于其他处理;5)利用隶属函数对幼苗生长指标进行综合分析,综合评价排名前3的依次是T14(20%泥炭土+27%珍珠岩+27%杉木皮+26%稻谷壳)、T5处理(60%泥炭土+40%珍珠岩)和T1处理(100%泥炭土)。考虑到泥炭土成本较高,因此,T5和T14处理为本研究中适合于杉木洋-061容器苗生长的轻型基质配方。
