随着交换技术的飞速发展,程控交换软件的规模越来越大,改动也越来越频繁,如何使代码对数据的改动具有相对的稳定性成为程控软件设计的一个首要问题。本文以CCS7(7号公共信道信令)为例,从对象模型、动态模型、功能模型3个方面阐述了OO(面向对象)方法在CCS7软件设计中的应用。这一方法,也可应用于程控软件的设计。 相似文献

Static and dynamic average polarisabilities and polarisability anisotropies of seven linear non-polar and polar molecules are calculated within the CCS, CC2, and CC3 approximations using a range of medium-sized basis sets: the polarised LPol-n (n = ds, dl, fs, fl), the aug-pc-n (n = 1, 2), the def2-SVPD, and -TZVPD basis sets. Reference values are obtained using a hierarchy of Dunning's (d-)aug-cc-pVXZ (X = D, T, Q, 5) basis sets. The results are discussed together with the available CCSD values in terms of basis set and correlation method errors, and their ratio. Detailed analysis shows that already the def2-SVPD basis set can be used in CCS polarisability calculations. When affordable, the slightly larger aug-pc-1 basis set is recommended, as it leads to significant reduction of basis set error. The def2-TZVPD, LPol-ds, and aug-pc-2 basis sets are optimal choice within the CC2 approximation, with the latter allowing to approach the CC2 basis set limit. The LPol-ds, -dl, and def2-TZVPD sets outperform the aug-cc-pVTZ set in average polarisability CCSD calculations, with the def2-TZVPD being competitive to other reduced-size sets also in determination of polarisability anisotropy. The aug-pc-2 basis is a particularly attractive choice for CCSD, giving the accuracy of aug-cc-pVQZ at a significantly reduced computational cost. The polarisability anisotropy is shown to be more computationally demanding than the average polarisability, in particular with respect to the accuracy of the correlation method and an accurate evaluation of this property requires at least the CCSD model. 相似文献

CCSDS分包遥控协议分析 总被引:1,自引:0,他引:1
空间数据系统委员会(CCSDS,Consultative Committee for Space Data System)所发布的标准在窄间数据通信领域起着极其重要的作用,很多标准已经转化为ISO国际标准。分包遥控(TC)协议主要用于地面对航天器的控制,其安全性和准确性对航天器至关重要。着重对TC协议进行通信进程演算(CCS),通过演算没有发现协议中有死锁与活锁等问题,为今后CCSDS协议(如PSLS)的开发提供了有效的分析方法。 相似文献
