	1	An Arecibo follow-up study of seven pulsars discovered by Five-hundred-meter Aperture Spherical radio Telescope(FAST)显示文摘We present Arecibo 327 MHz confirmation and follow-up studies of seven new pulsars discovered by the Five-hundred-meter Aperture Spherical radio Telescope(FAST).These pulsars are discovered in a pilot program of the Commensal Radio Astronomy FAST Survey(CRAFTS)with the ultra-widebandwidth commissioning receiver.Five of them are normal pulsars and two are extreme nulling slow pulsars.PSR J2111+2132’s dispersion measure(DM:78.5 pc cm^(-3))is above the upper limits of the two Galactic free electron density models,NE2001 and YMW16,and PSR J2057+2133’s position is out of the Scutum-Crux Arm,making them uniquely useful for improving the Galactic free electron density model in their directions.We present a detailed single pulse analysis for the slow nulling pulsars.We show evidence that PSR J2323+1214’s main pulse component follows a non-Poisson distribution and marginal evidence for a sub-pulse-drift or recurrent period of 32.3±0.4 rotations from PSR J0539+0013.We discuss the implication of our finding to the pulsar radiation mechanism.	王珅朱炜玮李菂潘之辰王培 James M.Cordes Shami Chatterjee 姚菊枚钱磊岳友岭张蕾赵汝双王双强牛佳瑞袁懋缪晨晨谢晓尧刘志杰于徐红游善平孟令祺 FAST Collaboration	2021	Research in Astronomy and Astrophysics2021，21，10：	1
	2	肝脏海绵状血管瘤——诊断方法的比较显示文摘继超声显象之后,机械控制静脉团剂注射造影剂的动态CT扫描成为肝脏血管瘤的最佳诊断方法.彩色多普勒超声显象、血池闪烁摄影和磁共振是补充方法.	R.Langer M.Langer R.Felix C.Zwicker J.Treisch F.Astinet R.Bittner und M.Cordes 蔡培华	1991	放射学实践1991，6，4：	0
	3	内分泌性眼眶病的磁共振诊断显示文摘磁共振断层摄影应用的指征范围随着经验的不断增加而扩大.这是对CT检查的重要补充,它能对组织进行鉴别.内分泌性眼眶病就是一个例证.	N.Hosten Ch.Schubert M.Cordes R.Schneider R.Felix 储凤梧	1991	放射学实践1991，6，4：	0
	4	Scintillation optics of pulsar binaries and microstructure in the local ionized interstellar medium显示文摘Interstellar scintillation(ISS)caused by scattering from electron density microstructure(?1 AU)provides unequaled spatial resolving power for a number of applications in astronomy.These include studies of the interstellar medium on scales as small as 100 km and constraints on emission structure in the magnetospheres of compact objects on similar scales.

	5	Probing turbulence in galaxies with fast radio burst scintillation显示文摘Interstellar scintillation(ISS)is a well-known phenomenon observed from pulsars in the Milky Way.It comprises intensity variations vs.time and frequency caused by constructive and destructive interference from multipath propagation,which is due to diffraction from fluctuations in electron density in the interstellar medium(ISM)on scales as small as~100 km.These density fluctuations appear to be part of a turbulence process combined with discrete structures in electron density from other astrophysical processes;together these fluctuations extend to scales of pc or larger.

	6	结节性和弥漫性甲状腺肿B超和同位素扫描的对比研究显示文摘B超和同位素扫描系甲状腺疾病的辅助诊断方法,根据目前的知识和经验能作出很好的鉴别诊断。	K.Rosenkranz R.Langer M.Cordes 乐桂蓉	1991	放射学实践1991，6，2：	0
