用于直升机现场计量的低频振动校准技术

本文面向直升机健康与使用监测系统(HUMS)的现场计量保障需求,针对其中振动传感器在低频段尚无法实现现场校准的现状,提出了基于直线电机驱动技术的便携式低频振动校准技术方案。该方案利用高精度直线电机构造低频标准振动源,采用稳定性高的石英挠性加速度计作为标准加速度计,具有体积小、精度高、现场环境适应性好的特点,非常适用直升机HUMS的现场计量保障。根据不确定度评估结果,该方案能够实现0.5Hz～20Hz频率范围,0.01m/s~2～20m/s~2加速度范围内不超过1%的校准不确定度(k=2)。

中国文化产业进入东盟市场的可行性

中国与东盟各国的人文背景相通,民族语言互通,在宗教信仰上相同或相似,生计方式互补,文学艺术相互渗透.若借助上述有利的人文条件,可以顺利地将中国文化产业推向东南亚各国,获得可观的经济效益.困难之处在于上述各国大多存在着较为尖锐的民族对立,政治体制与宗教政策差异较大,展开此类商贸活动,很难获得各国官方的认可和全力支持.此外,上述各国对中国侨民的政策差异甚大,一些国家对华侨抱有偏见.因此,最好采用民间文化交流方式或通过私营企业渠道推进我国文化产业发展.

Numerical modeling of inhomogeneous orographic wave influence on planetary waves in the middle atmosphere

Parameterization of dynamical and thermal effects of stationary orographic gravity waves (OGWs) generated by the Earth’s surface topography is incorporated into a numerical model of general circulation of the middle and upper atmosphere. Responses of atmospheric general circulation and characteristics of planetary waves at altitudes from the troposphere up to the thermosphere to the effects of OGWs propagating from the earth surface are studied. Changes in atmospheric circulation and amplitudes of planetary waves due to variations of OGW generation and propagation in different seasons are considered. It is shown that during solstices the main OGW dynamical and heat effects occur in the middle atmosphere of winter hemispheres, where changes in planetary wave amplitudes due to OGWs may reach up to 50%. During equinoxes OGW effects are distributed more homogeneously between northern and southern hemispheres.     

Mathematical modeling of plasma drifts over equatorial low latitude regions

This paper presents a mathematical model to simulate ionospheric plasma drifts at equatorial low latitude regions by coupling of E- and F-regions. The governing non-linear differential equations (of elliptic and parabolic nature) are solved numerically through finite-difference schemes and obtained neutral winds and electric fields. The temperature and electron density profiles are generated utilizing MSIS-86 atmospheric model. The continuity equation is employed to obtain night-time E-region density profile using measured ionograms at Trivandrum (India). The computed vertical and zonal plasma drifts are comparable with measured Jacamarca plasma drifts with little variations during noon and evening times. The plasma drifts at Trivandrum (8.5° N, 76.5° E, dip 0.5° N) are compared with those of Jicamarca (12° S, 76.9° W, dip 2° N). Neutral wind simulations of present model agree well with those of horizontal wind model (HWM-93). The post-sunset enhancement and its reversal are also discussed.
