Near-Infrared Spectroscopy of McNeil's Nebula Object

, 2004
We present 0.8-5.2 micron spectroscopy of the compact source at the base of a variable nebula (McNeil's Nebula Object) in the Lynds 1630 dark cloud that went into outburst in late 2003.

AKARI Near-Infrared Spectroscopy of Luminous Infrared Galaxies

, 2012
We present the AKARI near-infrared (NIR; 2.5-5 micron) spectroscopic study of 36 (ultra)luminous infrared galaxies [(U)LIRGs] at z=0.01-0.4. We measure the NIR spectral features including the strengths of 3.3 micron polycyclic aromatic hydrocarbon (PAH ...

Rotationally resolved spectroscopy of (20000) Varuna in the near-infrared [PDF]

, 2014
Models of the escape and retention of volatiles by minor icy objects exclude any presence of volatile ices on the surface of TNOs smaller than ~1000km in diameter at the typical temperature in this region of the solar system, whereas the same models show

无创颅内压监测的研究进展 Research Progress of Noninvasive Intracranial Pressure Monitoring

Zhongguo cuzhong zazhi
颅内压是指颅腔内容物对颅腔壁的压力，其变化能反映颅内的生理、病理变化情况。成人平卧位的颅内压持续维持在15 mmHg（1 mmHg=0.133 kPa）以上，即为颅内高压。目前，颅内压的监测方法以有创的脑室外引流和实质内探针为“金标准”，然而该方法存在感染风险高、易导致脑损伤和出血等缺陷，且成本高昂。鉴于此，探寻一种安全、精确的无创颅内压监测手段显得尤为关键。本文综述无创颅内压监测的最新研究进展，比较分析了多种技术方法的优势与缺陷，脑成像技术、TCD、脑电图 ...

Near infrared spectroscopy of W51 IRS-2 [PDF]

, 1982
Near-infrared spectra at 2.95-3.5 μm and 3.99-10 μm have been obtained towards W51 IRS-2 and its surroundings, in order to investigate the spatial variations in intensity of the 3.28 μm unidentified feature and the 4.05 μm Brackett-α line. The Br-α and 3.
