PM technique

The ENA polypeptide in sera of 52 patients with dermatomyositis ( DM)/ polymyositis ( PM) were measured by immunoblotting technique, the positive rate of Jo 1 antibody is 13.3% and 31.8% respectively.

应用免疫印迹技术测定52例皮肌炎和多发性肌炎病人血清可提取性核抗原（ENA）多肽抗体，其中Jo－1抗体的阳性率分别为13.3%和31.8%。

A 15% SiC_p/ 2009Al composite was fabricated by high energy milling powder metallurgy ( PM) technique. The effect of velocity and time of milling as well as PM procedure on mechanical properties of the composite was investigated.

采用高能球磨粉末冶金法制备了15%SiC p/2009Al复合材料，研究了球磨转速、球磨时间、加热抽真空工艺、热压成型以及热挤压比对复合材料力学性能的影响。

Objective: To study the pathogenesis of polymyositis ( PM) by using immunohistochemistry staining and electron microscope technique.

目的：本研究旨在采用免疫组织化学技术及电镜技术对多发性肌炎（PM）的发病机制进行研究；

Traditional PM focuses on the quality, cost and progress of projects, while modern PM emphasizing on unconventional technique and a new definition for project manager.

传统项目管理关注的焦点是项目质量、成本和进度。而现代项目管理要以非传统的项目管理技术和重新定义项目经理的作用。
