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。

The main causes of the vibration in pipeline system are in two respects : The first is the vibrant force of the medium acted on pipeline system,i.e.exciting signal,such as the vibrant force caused by the gas flow at the compressor ′ s inlet and outlet and at the ramified and nodel points as well as the action of pig passing through pipeline bridge,etc.;The second is the response to the exciting signal,which is relating to the characteristics of the pipeline system,i.e.the rigidity,support,quality and equipments of the system besides the waveform of the exciting signal.

管道系统振动的原因主要有两方面，一是介质对管道系统产生的振动力，即激发信号，如气流在压缩机进、出口，分支节点部位产生的振动力，清管器通过管桥时对它的作用等；另一方面是对激发信号的响应，其响应除了和激发信号的波形有关外，还和管道系统本身的特征，即系统的刚度及支撑，质量及其配置等情况有关。

The dynamic measuring method of alignment parameters based on the Satisfaction Criterion Model is presented in this paper. Using the quadratic regression crosscut combination method to organize the experiment, the mapping relationship between side force of slippage and camber angle and toe-in of the testing vehicles is obtained by regressing the experiment data. In this experiment, side force and slippage are testing objects, camber and toe-in value are testing factors.
