广州化工 2014年第18期42卷 146-148页

作者：皮向东湖北省产品质量监督检验研究院湖北武汉430061

《工作场所空气中有害物质监测采样规范》（GBZ159-2004）[1]、《工作场所空气有害物质测定》（GBZ/T160.1~160.85）中明确规定了工业企业生产时工作环境中的各类化学有害物质及粉尘的检测采样、测定方法和技术规范[2],如何正确理解、... 详细信息

《工作场所空气中有害物质监测采样规范》（GBZ159-2004）[1]、《工作场所空气有害物质测定》（GBZ/T160.1~160.85）中明确规定了工业企业生产时工作环境中的各类化学有害物质及粉尘的检测采样、测定方法和技术规范[2],如何正确理解、掌握此类检测规范,搞好企业职业病防治、职业卫生检测及评价工作,是我们要重视的问题。本文运用不确定理论对工作场所等环境中有毒有害物质现场采样的准确性进行探讨[3-4],结果表明：采样体积不确定来源主要有采样流量、测量重复性、大气压、温度及采样时间等,而流量计刻度标定不准和重复性是影响采样体积不确定度的主要因素。应采取必要的措施,降低采样体积偏差,才能保证工作场所有害物检测的准确性。

Joint Multimodal Aspect-based Sentiment Analysis(JMASA)is a significant task in the research of multimodal fine-grained sentiment analysis,which combines two subtasks:Multimodal Aspect Term Extraction(MATE)and Multimodal Aspect-oriented Sentiment Classification(MASC).Currently,most existing models for JMASA only perform text and image feature encoding from a basic level,but often neglect the in-depth analysis of unimodal intrinsic features,which may lead to the low accuracy of aspect term extraction and the poor ability of sentiment prediction due to the insufficient learning of intra-modal *** this problem,we propose a Text-Image Feature Fine-grained Learning(TIFFL)model for ***,we construct an enhanced adjacency matrix of word dependencies and adopt graph convolutional network to learn the syntactic structure features for text,which addresses the context interference problem of identifying different aspect ***,the adjective-noun pairs extracted from image are introduced to enable the semantic representation of visual features more intuitive,which addresses the ambiguous semantic extraction problem during image feature ***,the model performance of aspect term extraction and sentiment polarity prediction can be further optimized and *** on two Twitter benchmark datasets demonstrate that TIFFL achieves competitive results for JMASA,MATE and MASC,thus validating the effectiveness of our proposed methods.

人工智能生成虚假信息涉及多种情形,难以在现有法律体系下得到有效控制,应以人工智能系统为防控对象构建安全风险防控体系,当前国际社会和我国采取的是客体式防控,主体式防控不利于实现人工智能系统的可控性和消除人工智能生成虚假信息危害。深度合成、生成式等人工智能系统是与公众交互信息的人工智能系统,对其生成虚假信息的治理应当以系统提供者、运营者承担安全管理义务为重点,当前我国相关立法不完善,欧盟《人工智能法》中的安全风险类型化防控机制具有借鉴价值。基于风险防控的有限规范责任理论可以为人工智能安全管理义务承担者负刑事责任提供理论支持,有必要设立故意违反人工智能安全管理义务犯罪,该罪的性质是违反特殊的公共产品运行安全管理义务的不作为犯,犯罪主体应当限定为人工智能系统提供者和运营者,处罚造成严重后果或有其他严重情节的行为。
