First and foremost,the definition of the PSSn is shown and the calculation procedure of the PSSn at the work condition where the telescope aberration is much smaller than seeing is presented to reveal the relationship between PSSn and seeing.Then,the optical degradation due to vibration is achieved by the two methods: one is the statistics moment for the arbitrary froms of vibration and other one is spectrum method for wind load. After the theoretical presence,the simulation is processed. The multi-axis-accelerometers are used to achieve the motion of the mirror. After integrated to displacement signal,the measured signal is applied to the mathematical model of the GSSM and the optical performance degradation under certain mechanical vibration can be achieved. The PSSN flows from 0.996 to 0.994 under some dynamic vibration. And then,the wind load is applied to the mathematical model using spectrum method with the PSSN flows from 0.996 to 0.991. This paper can help the system engineers to predict the performance of the GSSM in various work condition. What is more,PSSn is able to be combined just by simple multiplication,so the optical performance degradation can be easily co-considered with other error sources.展开更多

Over thirty million oppressed blacks finally won their freedom to becomemasters of a new nation born in the firstever all-race election held last April. The African National Congress (ANC), with years of anti-apartheid record,won 252 seats in the election to the 400-seat National Assembly to come out as thelargest party of the country, followed by the original ruling National Party (NP)with 82 seats, the Inkatha Freedom Party (IFP) with 43 seats and others with 23seats. ANC President, world-famous black leader Nelson Mandela, was elected asthe first black State President and the organization’s National Chairman ThaboMbeki as First Deputy President. F.W. de Klerk, former State President andleader of the National Party remained in the new government as the Second DeputyPresident. An ANC-led government of national unity was inaugurated and swornin on May 10.展开更多
