微动

A simplified vessel network consisting of arteriole, open and reserved capillaries, venule, initial lymphatics and arteriole-venule anastomose is adopted as the geometrical model.

几何模型是一个包括微动脉、开放与储备毛细血管、微静脉、初始淋巴管和微动静脉吻合支的简单网络。

In this work,based on the principle of microdoppler,the mathematical model between missile and decoy is constructed,and characteristics in microdoppler are analyzed through simulation,thus distinguishing the target from heavy decoys and the missile.It offers a new reassuring way to the discrimination of the real or false targets.Keywords : target recognition;warhead;decoy;microdoppler;micromotion

文中在对微动目标微多普勒分析的基础上，建立了导弹与诱饵的数学模型，采用短时傅里叶变换的方法对回波信号进行微多普勒特征提取，仿真分析了导弹与诱饵的微多普勒特征，通过研究其时频分布特点的差异成功的识别出了真假目标，从而为弹道导弹与重诱饵的识别提供了一个新的有效方法。

Abstract］ objective to provide the experience on treatment with the internal fixation to the fractures combined with/without dislocation on peripheral amphiarthrodial joint.methods from january 2000 to january 2005,62 cases were follow-up visited and evaluated on imageology,imaging,joint function and complication,et al.results serveral problems were observed on these cases.first,when the internal fixation were pulled out,some of the patients were observed the disturbance,even loss on joint function,and their quality of life were limmited.second,some internal fixations had been broken before they were pull out.conclusion we should sufficiently allow for not only the stabilization and the union of the fracture,but also degrade the complication to minimum limit and maximally recover the joint function.

作者：洪洋，陈峥嵘，董有海，钱光，杨群，程根祥目的通过对微动关节周围骨折和合并关节脱位的内固定治疗后的疗效分析，进而为临床治疗提供经验。方法对2000年1月～2005年1月期间62例患者进行随访，并从影像学及关节功能、并发症等方面进行评估。结果治疗该类创伤病例存在着以下几个问题：（1）部分患者的关节功能在内固定解除术后，存在着不同程度的功能障碍，甚至丧失而影响到患者的生活质量。（2）并发内固定断裂情况时有发生。结论治疗微动关节周围骨折尤其在合并有关节脱位时，应充分考虑到既要修复因创伤引起的骨折使其愈合并使该关节稳定，又应该最大限度地恢复关节功能，并将并发症降低到最小限度。

The results showed that the synergistic effect was remarkable, while mechanical action was the dominative factor for inducing damage.

结果表明，材料微动过程力学化学作用相互促进，力学损伤在微动损伤过程中占居主导作用。

Symptoms of cemented femoral prostheses the same as the uncemented femoral prostheses were present in male patients at 60-70 years and in female patients older than 55 years old.

骨水泥型股骨假体上的整体应力在男性60~70岁年龄段分布相对较均匀，初始微动变化较小；在女性55岁后分布相对较均匀，初始微动变化较小。

RESULTS: Relatively well-distributed whole distress and slight initial micromovement of uncemented femoral prostheses were found in male patients at 30-60 years old and in female patients at 40-55 years old.

结果：生物型股骨假体上的整体应力在男性30~60岁年龄段分布相对较均匀，初始微动变化较小；在女性40~55岁年龄段分布相对较均匀，初始微动变化较小。

Furthermore, the connection between two sesamoids and metacarpal was a kind of soft tissue connection which seemed like fabric, it could exist mini-motion between two sesamoids and metacarpal, resulting in the increasing friction between the tendon of flexor pollicis longus muscle and sesamoids. Meantime, it could lead to metacarpophalangeal joints dislocation and injury the tendon sheath of flexor pollicis longus muscle.

而且，籽骨和掌骨之间没有骨性连接，为纤维软骨样软组织连接，导致籽骨和掌骨之间可以微动，拇指屈伸时，籽骨和掌骨间的微动导致拇长屈肌腱与籽骨摩擦进一步加大，籽骨易脱位，产生籽骨嵌顿于掌指关节，造成拇长屈肌腱狭窄性腱鞘损伤。

Pure water and acidrain could transform the partial slip regime of steels (45# steel, GCr15 steel and 0Cr18Ni9 stainless steel) to small displacement amplitude, resulting in a wide mixed regime and gross slip regime.

纯净水和酸雨介质改变了三种钢的微动运行区域，使部分滑移区向小位移方向移动，混合区和滑移区变宽：海水使0Cr18Ni9钢的部分滑移区向小位移方向移动，但对45~#和GCr15钢的微动运行区域无明显影响。
