教育教学活动中的师生人际冲突及其解决方法

受传统观念的影响,人们一般只看到师生人际冲突的负面影响,而很少注意其正面作用;实际上,师生人际冲突是教育教学的互动形式之一,它的存在是必然的,也是合理的,它既有消极有害的一面,也有积极有益的一面。文章试在分析师生人际冲突原因的基础上,针对其影响的二重性,从学校、教师、学生三个方面,提出了正确对待师生人际冲突的建设性对策。     

Atlas II and IIA analyses and environments validation

General Dynamics has now flown all four versions of the Atlas commercial launch vehicle, which cover a payload weight capability to geosynchronous transfer orbit (GTO) in the range of 5000–8000 lb. The key analyses to set design and environmental test parameters for the vehicle modifications and the ground and flight test data that validated them were prepared in paper IAF-91-170 for the first version, Atlas I.

This paper presents similar data for the next two versions, Atlas II and IIA. The Atlas II has propellant tanks lengthened by 12 ft and is boosted by MA-5A rocket engines uprated to 474,000 lb liftoff thrust. GTO payload capability is 6225 lb with the 11-ft fairing. The Atlas IIA is an Atlas II with uprated RL10A-4 engines on the lengthened Centaur II upper stage. The two 20,800 lb thrust, 449 s specific impulse engines with an optional extendible nozzle increase payload capability to GTO to 6635 lb. The paper describes design parameters and validated test results for many other improvements that have generally provided greater capability at less cost, weight and complexity and better reliability. Those described include: moving the MA-5A start system to the ground, replacing the vernier engines with a simple 50 lb thrust on-off hydrazine roll control system, addition of a POGO suppressor, replacement of Centaur jettisonable insulation panels with fixed foam, a new inertial navigation unit (INU) that combines in one package a ring-laser gyro based strapdown guidance system with two MIL-STD-1750A processors, redundant MIL-STD-1553 data bus interfaces, robust Ada-based software and a new Al-Li payload adapter. Payload environment is shown to be essentially unchanged from previous Atlas vehicles. Validation of load, stability, control and pressurization requirements for the larger vehicle is discussed.

All flights to date (five Atlas II, one Atlas IIA) have been successful in launching satellites for EUTELSAT, the U.S. Air Force and INTELSAT. Significant design parameters validated by these flights are presented. Particularly noteworthy has been the performance of the INU, which has provided average GTO insertion errors of only 10 miles apogee, 0.2 miles perigee and 0.004 degrees inclination. It is concluded that Atlas II/IIA have successfully demonstrated probably the largest number of current state-of-the-art components of any expendable launch vehicle flying today.

Launch and early operations of Herschel and Planck

On 14 May 2009 the European Space Agency launched 2 space observatories: Herschel (with a 3.5 m mirror it is the largest space telescope ever) will collect long-wavelength infrared radiation and will be the only space observatory to cover the spectral range from far-infrared to sub-millimetre wavelengths, and Planck will look back at the dawn of time, close to the Big Bang, and will examine the Cosmic Microwave Background (CMB) radiation to a sensitivity, angular resolution and frequency range never achieved before. This paper will present the Flight Dynamics, mission analysis challenges and flight results from the first 3 months of these missions.Both satellites were launched on the same Ariane 5 and travelled to the L2 Lagrange point of the sun–earth system 1.5 million km from the earth in the opposite direction of the sun. There they were injected to a quasi-halo orbit (Herschel) with the dimension of typically 750,000 km×450,000 km, and a Lissajous orbit (Planck) of 300,000 km×300,000 km.In order to reach these Lissajous orbits it is mandatory to perform large trajectory correction manoeuvres during the first days of the mission. Herschel had its main manoeuvres on the first day. Planck had to be navigated on the first day and by a mid-course correction manoeuvre, the L2 orbit insertion manoeuvre was planned on day 50. If these slots were missed, fuel penalties would rapidly increase.This posed a heavy load on the operations teams because both spacecrafts have to be thoroughly checked out and put into the correct modes of their attitude control systems during the first hours after launch.The sequence of events will be presented and explained and the orbit determination results as well as the manoeuvre planning will be emphasised.

SMOS与Aquarius卫星海表盐度测量方法及数据的对比分析

国际上发射的海表盐度遥感卫星主要有2颗:欧洲的SMOS和美国的Aquarius卫星,为给后续海表盐度遥感提供参考借鉴,对比分析了这2颗卫星的遥感器载荷、数据处理算法和盐度数据。遥感器载荷方面,SMOS采用L波段二维综合孔径辐射计,而Aquarius采用L波段实孔径辐射计加散射计;数据处理算法方面,分析了二者在介电常数模型、海面粗糙度校正以及反演算法方面的差异;盐度数据方面,分析了SMOS与Aquarius盐度数据之间的相关程度,并分别与ISAS(In Situ Analysis System)浮标盐度数据作对比,分析了2颗卫星的盐度数据精度。将2颗卫星的盐度遥感数据与ISAS浮标盐度数据对比发现,在全球范围内,Aquarius盐度测量精度优于SMOS;但在开阔海域,SMOS盐度测量精度优于Aquarius;而在近海岸区域,均出现较大的误差,且SMOS数据误差更大。
