中国航天科工集团事业部制改革浅评

事业部制结构又称M型结构或多部门结构，也有人称其为多分支公司结构。它是现代大型企业常见的一种组织结构模式。在这种结构中，各事业部(或分支公司)通常是半自主的利润中心，企业往往以产品、服务、区域、客户或商标为依据，将相关的研发、采购、生产、销售等职能部门结合成相对独立的单位即事业部，实行集中决策指导下的分散经营，其显著特征是集权与分权的有机结合。

稳定人民币汇率:中国和世界经济增长的共同内在需要

中国经济在相当长的时间里一枝独秀的形势，引起了日本、美国的少数心怀叵测之人的嫉妒。日美强烈要求人民币升值，并改变我国现行的汇率制度。对这些非理性的要求，我国是明确予以拒绝的。如果人民币升值并发生波动，将对中国经济和世界经济带来灾难性后果。为什么自由浮动汇率会造成恶果呢?让我们用例子作出原理性解释吧。假设某个拥有50亿美元的大投机家，他以1：10的汇率购进某个实行自由浮动汇率东道国的500亿元本币进行炒汇，随后也有大量的小户投资人跟进。在接下来的投机中，这个大投机家的可能收入是：①若在汇率为9．1：1时抛出全部本币，他可收回约54．9亿美元；②若在汇率为8．33：1时抛出全部本币，他可以收回60亿美元。无论哪种情况出现，这个大投机家的汇率炒作都获得了巨额收益，即由50亿美元变成为54．9亿美元或60亿美元。实行自由浮动汇率的国家，有可能成为国际金融投机家的自动提款机。由此得到的结论是，一个国家为了自身的经济安全绝对不能搞自由浮动汇率；不能轻言开放资本市场；主权国家政府必须控制与本国经济规模相适当的外汇储备；我国现行的人民币汇率符合国情，能够有效地支撑我们参与国际竞争；人民币汇率长期稳定是中国经济和世界经济增长的共同内在需求。     

On the stability of the track of the space elevator

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.     

On the Possibility of the Existence of Volatile Compounds in the Region of the Scott Crater on the Moon

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.     

Estimation of the current density and analysis of the geometry of the current system surrounding the Earth

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.

Estimating the accuracy of the technique of reconstructing the rotational motion of a satellite based on the measurements of its angular velocity and the magnetic field of the Earth

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°.     

Optimization of the trajectory of the spacecraft insertion into the system of heliocentric orbits

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.
