objective:to study and analyze the features of lower limb fatigue fracture in the special force by means of radiodiag-nosis.methods:anterior-posterior and lateral films and clinical follow-ups were made to all the affected limbs in the56cases of lower limb fatigue fracture from june2003to feb.2006.results:through medical history and radiodiagnosis all the cases were giv-en definite diagnosis,achieved good treatment results and all had clinical follow-ups.the average length of clinical follow-ups was3months.following treatment,all patients returned to work and resumed training.conclusion:lower limb fatigue fracture finds a rather high incidence in the special force.special features could be seen in the x-ray film,which has obvious clinical significance in the differential diagnosis of other diseases.

摘要］ 目的：分析特种部队下肢疲劳骨折的x线特征性表现和鉴别诊断。方法：从2003年6月～2006年2月，对56例来院就诊治疗的下肢疲劳骨折的患者全部进行患肢x线正侧位片检查和随访。结果：本组病例依据病史和x线分析，均明确诊断，经治疗后效果好，全部获得随访，平均随访时间3个月；骨愈合时间1～2个月，全部恢复工作和训练。结论：下肢疲劳骨折在特种部队发病率高，x线片中具有特征性表现，与其他疾病的鉴别具有重要的临床意义。

Firstly, DWT is applied to the image, and moment invariants is extracted on fixed-size blocks of low-frequency component in wavelet sub-band to yield a reduced dimension representation.

然而，许多实际情况是要求在不依赖任何预签名提取或预嵌入信息的前提下，对图像的真伪和来源进行鉴别，这就是图像盲取证技术，也叫被动取证技术，它是一种新的图像鉴别分析思路。

Moreover, to suppress the non-Gaussian reverberation, the robustness of the spectrogram has been studied in this algorithm.

同时，本文也将传统的可鉴别性算法扩展到任意噪声污染下的信号可鉴别性算法。

In this paper,the advantage and disadvantage of several seal imprint recognition method have been compared,and an approach for seal imprint recognition based on ring projecting template matching is proposed.

As a result, some valuable taxonomicmethods, criteria and our viewpoints were concluded. The morphology ofthe sporus is the main identical base at species level, which include thecharacters of the shape, size, colour, septate and ornament of the wall etc,and some sporus with distinct variable are also useful at genus level.

孢子的特征(包括形状、大小、颜色、隔膜数和表面纹饰等)是种级分类的主要依据，一些形态差异较大的孢子可作为属的划分标准；其次，分生孢子梗的形态特征、产孢细胞的延伸方式及产孢方式也是主要的鉴别依据，对属级水平上该真菌的鉴别有重要意义；另外，培养特征及产孢表型可作为分类鉴定的必要、有益补充。

Singular value decomposition of matrix may be avoided in the process of feature extraction, which is simpler than that of previous technologies such as PCA.

在Yale和NUST603两个人脸库上与ORL和NUST603两个人脸库上分别检验了两种方法的识别性能，实验结果表明两种方法抽取的鉴别特征有较强的鉴别能力。

First of all, these two standards in the test project and test methods for perfect more standardized, science, and coupled with the standard abouttwoweeks divisions, increasing differentiation of qualitative test (including infrared identification and chemical identification) by the main identification to enhance strict control formula control, part of the application to natural or other plastic impersonatea butylbenzoic stopple stopple quality, control and standardize butylbenzoic stopple market.

首先，这两个标准在测试项目和测试方法上力求更规范、科学，并结合标准按材料划分的特点，增加了鉴别定性试验，目的是通过鉴别试验加强主配方控制，严控部分掺用天然或其它胶来冒充丁基胶塞，控制胶塞质量，规范丁基胶塞市场。

Key of Woody Species at Botanical Garden in Shanxi Agricultural University;2. The key to the main herbage landscape plants from Guangzhou;3. Key s to females and males of this subgenus were given.

结果 记述了中国库蠓属三囊亚属的鉴别特征，其在国内的分布现已知有 3 3种，报道了主要鉴别特征的测量值，编制了雌虫和雄虫的分种检索表。

This paper presents a research on the algorithm of optimal set of statistically uncorrelated discriminant vectors.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
