Through the analysis of the experimental and numerical calculation values, hereinafter gives the description of the characteristics of the flow and heat transfer within the rotating blade cavity. Influenced by the inflow structure and the centrifugal force, the air flow rate on the top of the blade is bigger than that at the bottom, therefore, there exists radial component velocity which may make the buoyancy force weaken the heat transfer behavior of the blade.

通过实验和数值计算的结果的分析，发现气流在旋转叶片腔内的一些流动和换热特征：在进口流动结构影响和离心力的作用下，使得叶片顶部的气流流量大于底部的流量，因此流体存在径向分速度，可能是这种径向分速度造成浮升力对叶片的换热起降低的作用。

The larger the handrim, the greater the moment about the wheel axle M could attain. The tangential force F applied to the handrim was similar among three handrim diameters. However, the radial component of force applied to the handrim increased as handrim diameter decreased.

结果发现，轮圈直径越大，最大前进力矩越大；不同轮圈直径，施加在轮圈的切线分力相似；但轮圈直径越小，施加在轮圈的轴向分力却越大；而轮圈直径越大，有效分力比率也越大。

Equations of the force acting on the oil droplet are given based on the analysis of radial pressure field. These equations point out that this force directs to the core and may improve the separation.

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。
