Results MPR and SSD techniques can acquire lots of important information:（1）rule out the diagnosis of frac-ture and dislocation and its type can be when patient has been injured so badly that cannot take X-ray examination.（2）detect the secret fracture and missing fracture in X-ray examination because of overlap.（3）diagnose the missing transverse fracture in routine CT scan.（4）diagnose the atlantoaxial joint luxation without fracture.

结果 MSCT扫描MPR、SSD技术在寰枢椎外伤中可：（1）对于外伤后病情不适合拍平片者，MSCT能快速、准确地明确骨折、脱位的有无及其类型；（2）MSCT轴位扫描结合MPR能排除因平片结构重叠漏诊的骨折以及平片不易发现的隐匿骨折；（3）MPR对椎体发生的常规轴位扫描易漏诊的水平型骨折线能明确诊断；（4）对于没有骨折的寰枢关节半脱位能提供可靠的依据。

Thus the universal nature of frac-tal structures in the weak interactions of solitary waves is analytically established. Tounderstand the fractal regime further, using asymptotic methods along separatrix orbits,a simple second-order map is derived.

为了更深入的理解分形出现的机制，沿着separatrix轨道运用渐近分析，我们得到一个简单的二阶映射，这个映射描述了动力学方程中动量的变化关系，经过变量变换以后，它不含任何参数，因此对于广义非线性Schro¨dinger方程中孤立波的弱相互作用都是成立的。

SEM analysis finds that the fractures are intercrystalline plus quasi-cleavage fractures under quasi-motionless state;with the increase of stress intensity factor,fractureschange from transcrystalline quasieleavage fractutes to microvoid-coalescence dimple plus cleavage frac-tures,The increase of fracture toughHess of 8090Al-Li alloy under high stress intensity factor is associ-ated with the deformation mechanism and the change of precipitation Free Zone of grain boundary.

扫描电镜分析发现，准静态下的断裂为沿晶和准解理混合断口；随着应力强度因于的增加，断裂从准解理断裂过渡到准解理和显微空穴聚集的韧窝断裂舶混合断口。高应力强度因于率下断裂韧度的提高与其变形机制和晶界无沉淀区的变化有关。

It was found that the impact toughness is obviously decreased when the laths of the acicular ferrite are coarsened,and the fracture morphology is changed from the dimple frac...

当针状铁素体条束比较粗大时，-50℃冲击试样的断裂方式从韧窝断裂转变为解理断裂，韧性明显下降。
