对我国工业经济效益的考核，迄今为止采用的仍是1998年进行试算，1999年按月对外发布的工业经济效益考核指标体系，经过6年多的运行，已经趋于成熟，一些问题却也随之暴露出来。同时，随着工业经济形态向知识经济形态的转变，可持续发展问题日益被人民所重视，客观上对工业经济效益的考核提出了新的要求，故对我国现行工业经济效益考核的指标体系做如下探讨。

To this end the original 'Blue Fox' radar is replaced by Ferranti 'Blue Vixen' coherent pulse-Doppler track-while-scan radar to improve acquisition and look-down capabilities, and other improvements are a MIL 1553B digital databus (making it possible to carry Sea Eagle anti-ship and ALARM anti-radar missiles) and the installation of the Marconi Sky Guardian 200 RWR, the JTIDS for secure voice and data links, two additional underwing hardpoints, wing tip stations for two AIM-9 Sidewinder short-range AAMs, wing improvements, a revised cockpit with HOTAS controls, larger drop tanks, provision for 25 mm Aden 25 cannon in place of the elderly 30 mm weapons, and possibly a Plessey missile-approach warning system.

为实现这一目的，原有的"蓝狐"雷达被新型的"蓝雌狐"连续波脉冲多普勒雷达替换，该雷达具有搜索的同时锁定目标的能力，可下视下射。其他改进包括加装军用1553B数据链，这使得MK2可以使用"海鹰"反舰导弹和ALARM反雷达导弹。另外加装了马可尼"天空哨兵200"通信系统，JTIDS保密语音及数据链路。增加了两个翼下外挂点，翼尖挂架可携带两枚AIM-9"响尾蛇"近距空空导弹。细节的改进还包括：机翼设计有所改进；改进的座舱设计；更大的副油箱；采用阿登25mm机关炮代替了以往的30mm机炮；可能加装了导弹告警系统。

In order to design a scheme to quantify the observation and to get the fusion estimation from the received bits,the estimation fusion problem was changed into that of decision fusion.The interval was divided into subintervals,each subinterval was assigned a hypothesis,suitable cost coefficients of each hypothesis was selected to form the Bayes cost functional,and a mapping from estimation fusion to decision fusion was constructed.

采用将区间划分，每一区间形成一个假设，规定假设之间合适的损失系数，将估计融合问题化为决策融合问题，运用成熟的决策融合的方法，对于现在研究还不成熟的估计融合传感器量化问题设计了一个解决方案，将决策融合的决策结果作为最终的估计，从而在观测被量化的条件下达到较优的估计效果。

Second, aminolysis of polystyrene and poly prepared by reversible addition-fragmentation chain transfer polymerization was investigated. The product of the former contains predominantly double molecular weight species by the formation of disulfide bond, whereas the latter formed coupled species which consequently cleaved to unimolecular weight species.

由RAFT聚合的机理可知，聚合最终得到的聚合物的结构包含双硫酯基团，它是聚合物链保持活性特征的重要体现，同时它为聚合物的端基官能化提供了一个重要的途径，其中氨解反应是一个被人们广泛采用的方法，它在很温和的条件下将端基去掉，同时还能将双硫酯端基变成硫醇端基。
