It is challenging to make an ultrafast diagnosis of the temporal evolution of small and short-lived plasma in two dimensions. To overcome this difficulty, we have developed a well-timed diagnostic utilizing an x-ray streak camera equipped with a row of multi-pinhole arrays. By processing multiple sets of one-dimensional streaked image data acquired from various pinholes, we are capable of reconstructing high-resolution two-dimensional images with a temporal resolution of 38 ps and a spatial resolution of 1. μm. The temporal fiducial pulses accessed from external sources can advance the precise timing and accurately determine the arrival time of the laser. Moreover, it can correct the nonlinear sweeping speed of the streak camera. The effectiveness of this diagnostic has been successfully verified at the Shenguang-II laser facility,providing an indispensable tool for observing complex physical phenomena, such as the implosion process of laser-fusion experiments.

目的:探讨陕西省人群体重指数(BMI)与高血压的关系,为人群高血压在BMI超过正常水平时的防治提供相应的依据。方法:采用分层多阶段随机抽样方法,对陕西省目标人群共1.649人进行相关问卷的调查以及基本指标测量,比较不同水平的BMI人群高血压患病率的差异,采取Logistic回归分析,了解不同水平的BMI以及参照性别、年龄等因素与高血压发病可能的关系。结果:在陕西省1.649名调查人群中,高血压患者有4067人,且在调查的人群中,当BMI水平达到超重及肥胖时,高血压的患病率出现明显的上升趋势(P1.,考虑年龄与性别的影响,经Logistic相关分析,不同水平下BMI与高血压仍有显著性意义(P1.。结论:在参照性别和年龄因素的影响下,当BMI的水平达到超重及肥胖时,人群中高血压的患病率呈现明显上升趋势,因此,维持BMI的水平在正常范围是高血压防治的重要手段。
