随着空管事业的迅速发展,尤其是在美国“9.11”事件后,我们经常会接触到“应急方案”、“应急处置措施”、“应急保障预案”等,从空管行业特征和发展的要求来看,这些方案的制定、完善和实施越来越要求其具有指导性、严密性和可实践性,其根本目的就是要把突发事件或安全隐患遏制在萌芽状态,不让其造成严重后果或将突发事件的危害性降低到最小。这些大大小小的应急系统小到一台设备的应急,大到一个部门、一个机场的应急。  相似文献

2002年底至2003上半年爆发的非典疫情对我国社会造成了十分严重的危害。在严峻的形势下,我国政府充分发挥社会管理与公共服务职能,在短时间内集中大批的人力、物力,带领全国人民团结一心,众志成城,最终赢得了抗击非典的重大胜利。但是,面对成绩党和国家的领导人依然保持了清醒的头脑,敏锐地认识到我国在应对突发公共事件方面存在的各种问题和种种不足。非典过后,党中央、国务院一方面迅速进行社会秩序的恢复工作,另一方立即组织有关部门认真总结经验教训,并将提高全社会应对突发公共事件能力安排到了工作日程之中,明确提出了“要建立健全社会预警体系,提高政府应对突发事件和风险的能力,形成统一指挥、功能齐全、反应灵敏、运转高效的应急机制,提高保障公共安全和处置突发公共事件能力”的工作目标。  相似文献

A string moving with geostationary angular velocity in its radial relative equilibrium configuration around the Earth, reaching from the surface of the Earth far beyond the geostationary height, could be used as track for an Earth to space elevator. This is an old dream of mankind, originating about 100 years ago in Russia. Besides the question of feasibility from a technological point of view also the question concerning the stability of such a configuration has not yet been completely solved. Under the assumption that a proper material (carbon nanotubes) is available, making the connection possible technologically, we address the question of existence and stability of the radial relative equilibrium of a tapered string on a circular geosynchronous trajectory around the Earth, reaching from the surface of the Earth far beyond the geostationary height.  相似文献

In this paper, we analyze the illumination conditions, the thermal regime, and the possibility of deposits of volatile compounds existing in the vicinity region (NSR S5 region) near the southern pole of the Moon. It has been found that there are no permanently shadowed zones near the Scott crater and the NSR S5 region, though the temperature conditions allow the of compounds such as CH3OH, SO2, NH3, CO2, H2S, C2H4, and water to remain stable relative to evaporation for a long time (≥1 Gyr). It has been also shown that compounds like CO and CH4 cannot stably exist in these regions.  相似文献

The results of an investigation of the distribution of plasma pressure, pressure gradients, and magnetic field near the equatorial plane in the plasma ring surrounding the Earth under magneto-quiet conditions are presented. Observational data obtained during the international THEMIS mission are used. The picture of the distribution of transverse-current density near the equatorial plane was obtained under assumption of observing the magnetostatic balance condition at geocentric distances from 6 to 12R E. In estimating the integral transverse current it was accepted that in daytime sector the magnetic-field minima on magnetic field lines are not localized in the equatorial plane. Estimates of the integral transverse current were obtained, which demonstrate the possibility of closing nighttime transverse currents at geocentric distances of up to ~12R E inside the magnetosphere, which form a high-latitudinal continuation of the ring current.  相似文献

The paper has studied the accuracy of the technique that allows the rotational motion of the Earth artificial satellites (AES) to be reconstructed based on the data of onboard measurements of angular velocity vectors and the strength of the Earth magnetic field (EMF). The technique is based on kinematic equations of the rotational motion of a rigid body. Both types of measurement data collected over some time interval have been processed jointly. The angular velocity measurements have been approximated using convenient formulas, which are substituted into the kinematic differential equations for the quaternion that specifies the transition from the body-fixed coordinate system of a satellite to the inertial coordinate system. Thus obtained equations represent a kinematic model of the rotational motion of a satellite. The solution of these equations, which approximate real motion, has been found by the least-square method from the condition of best fitting between the data of measurements of the EMF strength vector and its calculated values. The accuracy of the technique has been estimated by processing the data obtained from the board of the service module of the International Space Station (ISS). The reconstruction of station motion using the aforementioned technique has been compared with the telemetry data on the actual motion of the station. The technique has allowed us to reconstruct the station motion in the orbital orientation mode with a maximum error less than 0.6° and the turns with a maximal error of less than 1.2°.  相似文献

The possibility of the spacecraft insertion into the system of operational heliocentric orbits has been analyzed. It has been proposed to use a system of several operational heliocentric orbits. On each orbit, the spacecraft makes one or more revolutions around the Sun. These orbits are characterized by a relatively small perihelion radius and relatively high inclination, which allows one to investigate the polar regions of the Sun. The transition of the spacecraft from one orbit to another has been performed using an unpowered gravity assist maneuver near Venus and does not require the cruise propulsion operation. Each maneuver transfers the spacecraft into the sequence of operational heliocentric orbits. We have analyzed several systems of operational heliocentric orbits into which the spacecraft can be inserted by means of the considered transportation system with electric propulsion (EP). The mass of the spacecraft delivered to these systems of operational orbits has been estimated.  相似文献
