In the paper ,microstructure evolutions, mechanical properties, small pox phenomenon on the surface, and corrosion mechanism of die-cast magnesium alloy AZ91D,have been investigated and discussed in detail by means of metallography, SEM, tensile strength testing and salt spraying test combined with computer-aided flow in die analysis, some important conclusions are got and listed in the following1 Structure of the die-cast magnesium alloy AZ91D is composed of global-like structure, which is fine and homogeneous, and actinomorphous dendritic grains.

本课题针对AZ91D压铸镁合金，通过金相分析、SEM分析、力学性能测试和盐雾实验，并结合计算机辅助模流分析，对薄壁镁合金压铸件3C产品的显微组织演化，力学性能，爆痘现象和腐蚀机理等进行了较为细致的研究和讨论，得到如下重要结论。

ABR, a highly useful clinical procedure as behavioral audiometric procedure are not sutiable, inconclusive.

目的复位和三枚空心钉内固定是目前治疗股骨颈骨折的常用方法，利用有限元方法对空心钉内固定手术进行力学综合分析，可以找出一种符合生物力学规律的内固定治疗方法。

objective: to investigate diagnosis and treatment choice of detrusor hypoactivity with impaired contractile function on voiding function in benign prostatic hyperplasia.methods:the clinical date of 48 bph patients with dhic were analyzed,including clinical diagnosis,urodynamic parameters,treatment and follow-ups.results:37 patients with detrusor instability and over 40 cmh2o bladder pressure were treated successfully by turp.the time of indwelling suprapubic punctural cystostomy cathter was(1~8)weeks.11cases without di and under 40 cmh2o bladder pressure were treated by suprapubic punctural cystostomy,accepted the test of urodynamics after(1~3)months.7 cases with di were treated successfully by turp,4 cases without di were indwelled suprapubic punctural cystostomy cathter all life.conclusion:dhic worsens the voiding function of the patients with bph,and the test of urodynamic is helpful to diagnose and could provide more convinced evidences for treatment of patients.

分析膀胱过度充盈所致逼尿肌损伤，引起膀胱逼尿肌收缩无力良性前列腺增生48例患者的临床资料，包括诊断，尿动力学检查，治疗及随访结果。结果：37例经尿流动力学检查，诱发存在逼尿肌不稳定，伴膀胱内压达40 cmh2o以上，采取turp，术后留置膀胱造瘘管（1~8）周后全部拔除，排尿通畅。11膀胱内压始终未达到40 cmh2o，且在膀胱注水充盈过程中无逼尿肌不稳定出现，行膀胱造瘘后出院，（1~3）个月后经尿动力学检查复查膀胱逼尿肌收缩力，其中7例膀胱逼尿肌收缩功能有恢复，行经尿道前列腺汽化电切术治愈；剩余4例膀胱逼尿肌收缩功能几乎无任何改善。长期留置膀胱造瘘治疗。结论：良性前列腺增生导致膀胱过度充盈所致逼尿肌损伤，引起膀胱逼尿肌收缩无力患者，术前应用尿流动力学检查对膀胱逼尿肌损伤程度进行认真分析，可进行有针对性的治疗。
