目的:直喷内燃机工作过程中,燃油通过喷油嘴上的微小喷孔(直径为100–200μm)输送到燃烧室内进行燃烧做功。为定量研究喷孔直径和长度等结构参数对燃油输运过程的影响,首先需要实现对这些结构参数的高精度测量。创新点:对喷油嘴喷孔入口和出口等重要结构特征进行精确地定义,实现喷油嘴微小喷孔的直径和长度的高精度自动测量。方法:1.基于同步辐射X射线CT扫描技术实现喷油嘴顶部结构的三维重构;2.结合几何学原理,从这些离散的三维数字结构数据中提取宏观几何特征参数。结论:1.对喷油嘴喷孔结构特征参数进行了精确地定义;2.基于微米级精度建立了喷油嘴喷孔直径和长度的自动测量方法,实现喷孔沿其轴线从入口到出口的直径分布的自动测量。

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in june 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in june 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

目的了解国内ICU收治患者的营养治疗实施状况。方法对国内116家医院的118个ICU内的患者进行营养治疗实施状况的横断面调查。以2017年4月26日0时所有在ICU内治疗的患者为调查对象,收集患者基本信息、2017年4月25日(即调查日)的营养实施和胃肠道耐受情况,以及患者的28 d临床转归情况。结果调查共收集病例1953例,女631例(32.4%),男1306例(66.9%),缺失16例(0.7%);年龄(64.1±19.3)岁(1950例)。患者GCS、SOFA和APACHEⅡ评分分别为(10.76±4.35)分(1749例)、(5.65±3.52)分(1783例)、(17.14±7.31)分(1792例)。28 d临床转归存活1483例(75.9%),死亡312例(16.0%),失访+缺失158例(8.1%)。除身高和体重(P=0.000)外,男性与女性患者在年龄、病情严重程度及28 d临床转归等方面差异均无统计学意义。1953例患者中,胃肠功能评估为正常或轻度损害占73.7%(1440例),中-重度损害占10.8%(210例),衰竭占1.7%(33例),13.2%(258例)的患者未做评估。截至调查日,69.4%(1356例)的患者已启动肠内营养(EN),36.4%(711例)的患者已启动肠外营养(PN)。调查日有营养摄入的患者1720例(88.1%)。1953例患者中明确有恶心、呕吐反流、误吸、腹痛、腹胀、腹泻(大便次数≥3次/d且量≥500 ml/d)等胃肠道不耐受表现的分别占总人数的4.8%(93例)、5.4%(105例)、0.9%(17例)、8.7%(170例)、27.5%(538例)和4.3%(84例)。在1270例使用EN的病例中,明确存在恶心、呕吐反流、误吸、腹痛、腹胀、腹泻等不耐受症状的分别占3.2%(40例)、4.3%(54例)、0.8%(10例)、4.4%(56例)、26.9%(341例)和5.4%(69例)。入ICU后24 h内开始EN治疗的患者占22.4%(437/1953),48 h内开始的占38.6%(754/1953),72 h内开始的占46.6%(911/1953)。患者入ICU后3 d总热卡(EN+PN非蛋白热卡)达标率为12.9%(78/607),7 d总热卡达标率为18.7%(189/1010),14 d总热卡的达标率为23.0%(305/1325)。入ICU后3、7、14 dEN达标率分别为9.9%(60/607)、15.0%(151/1010)和18.6%(246/1325)。结论目前我国ICU内的绝大多数患者均接受了营养治疗,其中EN的使用率明显高于PN;但EN的开始时间和达标情况仍不理想,且实施营养治疗时未能体现个体化差异,营养治疗的细节仍需要提高。

为更好地防控新型冠状病毒(2019-nCoV)医院感染,保障医疗机构医务人员及其他工作人员的安全,合理使用个人防护用品,中华预防医学会医院感染控制分会、中国医院协会医院感染管理专业委员会、中国感染控制杂志编辑委员会组织国内专家(包括赴武汉抗疫一线的部分专家)共同制定本共识。本共识主要适用于同时收治新冠肺炎患者和普通患者的医疗机构;指导疫情期间医疗机构一线医务人员合理有效利用防护用品,同时也覆盖了几乎所有非一线医务人员及其他工作人员的防护用品使用。本共识通过评估医疗机构工作人员新冠肺炎暴露的风险,根据暴露风险来确定不同区域不同岗位工作人员的个人防护标准。本共识主要内容还包括:个人防护用品介绍及适用范围,三级防护穿脱流程,个人防护用品异常的防范与应急处理,新型冠状病毒肺炎职业暴露处置流程。同时,本共识特别强调,要合理进行新冠疫情期间医疗机构区域划分,以及重点分诊岗位安排有经验的感染科或呼吸科医生参与分诊,这些是风险评估的前提要求;在选择个人防护用品时,既要防止防护不足,又要避免滥用与过度使用,以保障工作人员安全为前提,预防新冠肺炎医院感染。
