Our work includes: 1 Different from general target recognition problems, L2 normalized samples are applied to HRRP-based RATR to deal with the amplitude-scale sensitivity problem, therefore, geometrically speaking, HRRP samples spread on a unit hypersphere.

考虑到用于识别的HRRP样本在2-范数强度归一化后都位于单位超球面上，针对于幂次变换后趋于Joint-Gaussian分布的HRRP数据，提出了一种改进的基于子空间近似的统计识别方法。

The FHS-SVM based on the structural risk minimization criterion can solve the small sample learning problem, which can get a good shallow buried target and clutter classification performance with only shallow buried target training samples to obtain the parameters of hypersphere. Furthermore, the factors of misclassification risk and bury environment diversity are combined into the discriminator study procedure using the fuzzy membership of training samples, which improve the practical value of the FHS-SVM in shallow buried target discrimination.

FHS-SVM基于结构风险最小原理，在有效解决小样本学习问题的同时，只需要浅埋目标训练样本就能优化超球面参数，获得较好的浅埋目标和杂波分类性能；并且利用训练样本的隶属度将误判风险和埋设环境多样性等因素融入鉴别器学习过程，提高了FHS-SVM浅埋目标鉴别算法的实用性。

The iteration process of sampling and model updating forms a positive feedback after a good subset is sampled. The inlier samples will be sampled with a much larger probability than outlier samples after several iterations.

在首次获得正确模型之后，样本采样与模型更新构成了一个正反馈环节，经过若干次迭代后，正确样本被采样的概率远超过错误样本被采样的概率。

Followed by the decomposition phase is optimal feature subset selection, in which the optimal feature subset acquired the best divergence is obtained according to interclass/intraclass distance of the training samples. This procedure is implemented by a Genetic Algorithm, with each possible feature subset encoded as chromosome. Fitness scores in GA are calculated and evaluated based on Jeffries-Matusita distance of the selected training samples.

然后，对这些线性光谱特征利用遗传算法结合训练样本计算类内/类间距离搜索最优分类子集，其具体染色体编码取可能的特征号，适应度函数基于样本平均Jeffries-Matusita距离计算。

A great deal of bacteria was found intracellularly and extracellularly in these positive samples under transimission electron microscopy. 4. The nanobacteria which was identified by transimission electron microscopy was isolated from 5 atherosclerotic plaque samples.

阳性标本透射电镜观察见细胞间质和细胞浆内均有较多的细菌，细菌表面有一层致密的外衣。4.6例腹主动脉瘤粥样斑块标本中有5例分离培养出纳米细菌，阳性率为83.3％，并予以透射电镜鉴定。6。

FT-IR spectrum showed that the new bands at 3000cm-1~2700cm-1 and 1600cm-1~1400cm-1 were assigned to the C-H telescopic vibration and the framework vibration feature of imidazole ring, besides the characteristic bands of BMMs appeared in all samples, however, all of characteristic bands for imidazolium ionic liquid disappeared in the samples when calcined at 550oC, which implied that the structure of imidazolium ionic liquid has been destroyed during calcinations.

FT-IR分析测试中3000cm-1~2700cm-1及1600cm-1~1400cm-1波数范围内的谱带被认为是饱和的C-H伸缩振动和芳环骨架振动，说明离子液体的存在，这些峰只在萃取样品中出现，可见键连的离子液体的结构在焙烧过程中被破坏。
