一种基于混编的气溶胶光学厚度(AOD)反演的新方法

目前国内AOD反演专业性很强,需要通过使用者自己编程处理才能得到结果,速度很慢,无法实现异地处理。本文介绍了一种利用C#和IDL混合编程技术开发对CE318太阳光度计测量得到的直射太阳辐射数据进行处理,从而最终得到550nm气溶胶光学厚度的网络处理系统的新方法。文章给出了新方法的处理流程,详细介绍了混编机制在AOD反演系统开发中的实现方式,并且通过野外实验实测CE318数据对应用平台进行验证,从而提出了C#和IDL进行混合编程开展基于网络版的遥感数据定标和大气测量应用研究的优势。     

PDC磨损齿切削载荷与生热规律研究

目前在不同倾角和不同磨损等级下,对真实磨损齿切削载荷和生热规律缺乏进一步的研究.为此,通过单齿切削试验验证了在不同磨损程度和不同前倾角下磨损齿的相关性能,得出磨损齿在切削过程中三向力和温度等的变化规律.研究结果表明:P DC齿磨损越严重,达到同样切削深度所需要的力越大,磨损齿的切削力随着前倾角的增加而增大,在破岩过程中...     

Experimental studies of cusp stabilization in Keda Mirror with AXisymmetricity(KMAX)

Stabilization of the axisymmetric magnetic mirror relies on the pressure-weighted magnetic field curvature. We report a new experiment by configuring a magnetic cusp structure to stabilize m = 1 interchange mode in the KMAX tandem mirror. The cusp configuration is formed by reversing currents in the two side cell coils, and a stronger cusp can lead to a more stable plasma once the null point of the cusp is less than 35–40 cm away from the device axis. The density fluctuations measured by four ax...     

Particle simulations on propagation and resonance of lower hybrid wave launched by phased array antenna in linear devices

In this work, we performed first-principles electromagnetic-kinetic simulations to study a phased antenna array and its interaction with deuterium plasmas within the lower hybrid range of frequency. We first gave wave accessibility and resonance results, which agree well with theoretical prediction. In addition, we further investigated the antenna power spectrum with different antenna phases in the presence of the plasma and compared it with that in a vacuum, which directly indicates wave coupling and plasma absorption. Furthermore, for the case with zero phasing difference, our simulation results show that, albeit the launch is away from the accessibility region, tunneling effect and mode conversion occurred, which enhanced coupling and absorption. Moreover, consistent interactions between the injected wave and the plasma concerning various antenna phase differences are shown. We presented the inchoate response of the plasma in terms of the launching directions. Our results could be favorable for the engineering design of wave heating experiments with a tunable phased antenna array in linear devices, such as simple magnetic mirrors or tandem mirrors.
