水泥熟料中游离氧化钙(f-CaO)含量的传统人工离线检测缺乏时效性,不利于生产指导。针对离线检测的滞后问题和软测量模型中f-CaO含量与辅助变量的时序匹配问题,提出了一种基于卷积神经网络(convolutional neural network,CNN)和长短时记忆(long short-term memory,LSTM)神经网络的f-CaO含量预测模型。首先,利用滑动窗口截取辅助变量的区间数据;然后,采用CNN提取区间数据的时序特征;之后,构建LSTM神经网络模型;最后,控制截取辅助变量的延迟时间和间隔时间,根据模型预测拟合度提取辅助变量的最优时序特征。仿真结果表明,所提模型提高了水泥熟料中f-CaO含量的预测精度。

The diagnosis of Janus Stephens 1829 and a key to the Chinese species of the genus is provided. Janus rnegarnaculatus Liu ＆ Wei sp. nov. and J. rufus Liu ＆ Wei sp. nov. are described from China. Janus megamaculatus sp. nov. differs from its known congeners by the body very large, head and thorax yellow brown with few black macula, the abdomen yellow brown with transverse black bands, the mesoscutal middle lobe with a deep middle furrow and the apical sheath as long as the basal sheath. Janus rufus sp. nov. is similar to Janus xanthus Naito ＆ Smith, 1998 in structure but differs from the latter by the head and thorax almost entirely yellow brown, the antenna brown and about 2 times as long as head and thorax together, the hind femur yellow brown, the cell Rs in hindwing closed and cereus 0.14 times as long as the apical sheath.

液化天然气(LNG)的主要成分是甲烷,其主要用途是作为燃料,是目前最清洁的一种能源。LNG的体积是常温下天然气体积的1/625,因而便于运输和贮存。正是由于这一特点,LNG贸易早在几十年前就成为了世界上仅次于石油的一种能源贸易的主要形式。进口LNG不仅进口了能源,而且也进口了宝贵的冷能,但如果不利用其冷能则是极大的浪费。为此,在介绍日本LNG冷能利用情况的基础上,重点讨论了利用我国中小型LNG气化站的冷能生产液氧、液氮等液体空分产品的可能性及经济性。随着我国LNG进口量和自行生产量的不断加大,LNG冷能的利用必将受到高度重视并付诸实践。

我国已规划建设10个以上从国外进口LNG的大型接收站,还在不断建设一些中小型LNG气化站。进口LNG不仅进口了燃料,同时也进口了宝贵的冷能。不同气化管输压力下LNG的可利用冷能和冷能的品位或利用价值有很大的不同。阐述了常压LNG和加压LNG气化时可利用冷能的数量和冷能的品位或低温价值所发生的变化。讨论了LNG冷能的梯级利用和LNG加压气化后天然气的外输压力问题。认为目前我国最应关注的是以成熟的LNG冷能利用技术为基础,在现有和即将建设的LNG接收站尽可能充分地利用冷能。接收站在规划之初就应同时把冷能的利用给予通盘考虑。对接收站的建设提出了建议。

Background： Many studies have reported that depression and anxiety have bidirectional relationship with headache. However, few researches investigated the roles of depression or anxiety in patients with headache. We surveyed the prevalence of depression and anxiety as a complication or cause of headache among outpatients with a chief complaint of headache at neurology clinics in general hospitals. Additional risk factors for depression and anxiety were also analyzed. Methods： A cross-sectional study was conducted at 11 general neurological clinics. All consecutive patients with a chief complaint of headache were enrolled. Diagnoses of depression and anxiety were made using the Chinese version of the Mini International Neuropsychiatric Interview, and those for headache were made according to the International Classification of Headache Disorders, 2＇ld Edition. The headache impact test and an 11-point verbal rating scale were applied to assess headache severity and intensity. Logistic regression was used to analyze risk factors of patients with headache for depression or anxiety. Results： A total of 749 outpatients with headache were included. Among them, 148 （19.7%） were diagnosed with depression and 103 （13.7%） with anxiety. Further analysis showed that 114 （15.2%） patients complaining headache due to somatic symptoms of psychiatric disorders and 82 （10.9%） had a depression or anxiety comorbidity with headache. Most patients with depression or anxiety manifested mild to moderate headaches. Poor sleep and severe headache-related disabilities were predictors for either depression or anxiety. Conclusion： Clinicians must identify the etiology of headache and recognize the effects of depression or anxiety on headache to develop specific treatments.
