The Solidification temperature range was defined as 110-200℃ by DSC analysis. More accelerant used can increase the casing samples dynamic performance, but more than enough accelerant can induce a severe solidified reaction that result in a smaller polymeric meshwork and reducing the sample's performance. Normally the Accelerant dosage can be 2 portions; The Epoxy resin CFRP has a obvious better performances than the Vinyl-ester Resin CFRP, i.e. had a Bend Strength of 1516MPa, LSS of 85MPa, also Tg raised to 195~C~ When used the end-carboxyl polyether to reinforce the epoxy resin, the casing sample's SS, BS and Crack Elongation all increased geminately. The CFRP performance also increased a little, that is because the performance of the CFRP mainly contributed by the CF. The reinforced resin improved the interface between the CF and resin that contribute to the little increasing.

Degradation test in vitro was carried out in phosphate buffer solution (0.1M, pH7. 4) at 37 ℃. The buffer solution was changed daily. Degradation test in vivo was implanted the sample to subdermal in adult ICH rat in the scapular area lateral to the dorsal midline. At suitable time the samples were recovered. Molecular weight changes in surface layer and bulk of polymer sample were measured by GPC and weight loss was determined gravimetrically. It was found that the degradation behavior can be regulated by changing the composition of copolymers. The critical compositions from surface to bulk degradation behavior for PGCA, PLCA, PLMCA, PLDCA systems were 15-20, 20-30, 30- 40, 40 of mol percent GA or LA unit in copolymers, respectively. The degradation behavior of PGCA, PLCA, PLMCA, PLDCA systems were compared and analysed. Some factors influencing the degradation character, such as copolymer composition, hydrophobicity, crystallinity and enzyme affect etc. played important role.

On the base of the analysis about the cause why this type of systems is hard to be controlled a new FNN, the FNN based on hyper-cylinder clustering, is presented. By comparison with the FNN based on hyper-sphere clustering, for any sample to be clustered, the FNN based on hypercylinder takes not only its input sample but also its output value into consideration. And so it is impossible for any two samples with'close'input samples and'estranged'output values to be clustered in the same cluster.

借助于对非线性系统模型Ⅱ不可逆情形下难以控制原因的分析,提出了基于超柱体聚类的模糊神经网络,与基于超球聚类的模糊神经网络相比,这种模糊神经网络在聚类时不仅考虑样本中的输入向量,也考虑样本的输出值,因此不会将输入向量较接近而输出值差异较大的两个样本聚为一类。

As a differential detection is used between the intercarrier, the proposed algorithm overcome the high sensitivity to timing error of conventional algorithm and is robust to multi-path. The effect of sample frequency offset can't be ignored in a continuous OFDM system of a large number of subcarriers. The estimation precision of the conventional algorithm is low and the realization is complex. A joint estimation of sample frequency offset and fine frequency offset based on difference operation is proposed. As averaging use a large number of samples in a maximum likelihood algorithm, the estimation precision is very high. The use of difference operation cancel the effect of carrier frequency offset, and the proposed sampling frequency estimation algorithm is robust to carrier frequency offset.

最后,本文对连续系统中的采样频率和载波频率精同步技术进行较为深入的研究,由于子载波数目大的连续OFDM传输系统中,采样频率偏差不可忽视,以往的采样频率估计方法精度低、实现复杂,因此本文提出了一种基于差分处理的采样频率偏差和精载波频率偏差联合估计算法,利用了最大似然算法进行采样频率偏差的估计,由于采用了差分处理方法,消除了载波频率偏差对采样频率偏差估计的影响,采用的最大似然算法对大量样点进行平均化处理,所以,相对以往算法,提出的联合算法估计精度高,而且采样频率偏差估计对载波频率偏差具有鲁棒性。
