The stealth warplane for the microwave radar usually have complicated structures with the coating of wave absorption. On the base of calculation and modeling of the geometrical structure of the warplane in real size, the HF RCS of the air crafts under two different polarizations in different direction have been calculated with the FDTD. The result shows that the above mentioned stealth warplane have the obvious characterstics of frequency resonance, polarization and the relatively large RCS in HF Band 10-30dBm2, which can be used as the theoretical reference for selection of working frequency for sky wave OTH Radar and it also means that the sky wave OTH radar has good capability of anti-stealth targets quantitatively.

It was proposed in the 1960's and developed rapidly in the 1990's. However, some theory problems, for example, the fluid dynamics and mass transfer during the filling up period which could not be dealt with in conventional distillation theories has been remained unstudied. And the simulation and mathematical models have to be made based on some assumptions, which are different from the actual situation obviously. Therefore the further development of DACO was restrained in the past years.
该操作方法自20世纪60年代提出,90年代以来得到了迅速发展,但众多学者的研究基本上集中在优化操作及其与传统恒回流法的比较,而许多重要的基本理论问题至今缺乏研究,特别是传统精馏理论无法涉及的塔内无回流充液阶段的流体力学和传质问题一直没有得到很好解决,导致了动态累积循环操作法的数学模型和模拟计算只能以与塔内真实状况相差很大的简化假设为基础,这严重地阻碍着动态累积循环操作法的进一步发展。

Moreover, an improved upper bound on the average MAP decoding error probability of linear Slepian-Wolf systems for stationary memoryless sources is derived. Based on this improved bound, we analyze the performance of Slepian-Wolf systems based on LDPC codes and random permutations, and prove that under some conditions, all but diminishingly small proportion of LDPC encoders and permutations are good enough for the design of practical Slepian-Wolf systems when the coding length is very large.

Finally, the effect of the complete recycling use of distilled effluent on ethanol fermentation was examined in order to save the cost for the treatment of waste distillage and promote cleansing production. Based on the data of 13 circulations, although the average fermentation time needed to be extended to 30~40 hours, over 12.5% ethanol was achieved, at the same time, residual reducing sugar and total sugar were maintained below 0.70% and 0.90%, which indicates that the negative effect of the completely recycling use of waste distillage was limited, and the waste distillage can be completely recycled within the fermentation system.
