置换

The effect of reaming on intramedullary pressure and pulmonary fat embolization［J］.

全髋关节置换术后脂肪栓塞的早期诊断和治疗［J］。

At this point, sheet resistivity is minimal. Meanwhile, TCR and the refiring change ratio is near to zero. Compound inorganic binder was put forward firstly. The controllable regulation on refiring change ratio can be acquired by linear principle. When the volume ratio is 1:1, the best sintering temperature is 865℃.

实验发现，复合无机粘结相对膜层电性能和重烧变化率的影响近似满足线性复合效应；采用体积比为1：1的钙铝硅玻璃和铅硼硅玻璃作为复合无机粘结相，最佳烧结温度在865℃；铅硼硅玻璃与钌酸铋置换反应生成钌酸铅&过渡层&，实现界面的渐变，使膜层性能得到改善。

Of the hemiprosthetic hip joints were reinfected in the control group and the experimental group, respectively.

结论兔人工股骨头置换术后感染一期翻修时应用VCM-PMMA固定假体，能显著提高翻修的成功率。

The account receivable is an important asset of enterprises. The management of accounts receivable should emphasize the combination of everyday control and utilization. The utilizing means include accounts receivable mortgaging, remising and selling, discounting and replacing etc. These methods are similar in many aspects, but there is qualitative difference sometimes.

应收款项是企业的一项重要资产，对于应收款项的管理，应该强调日常管理和利用相结合，利用的方式包括应收款项抵借、让售、贴现及置换等，这些方式有许多相似之处，但有时也有质的区别。

The output is a permutation, or reordering, of the input.

输出是一个置换，或重新安排，输入。

One of the limitations of all of these studies was a higher preoperative activity level in the hip resurfacing cohort.

不过所有这些研究的缺陷在于所调查的接受表面置换的病人群体的术前活动度较高。

In this review, we have identified several potential areas for further innovation in these contemporary hip resurfacing arthroplasty designs.

本文中我们认为改进表面置换假体的设计有多个潜在领域。

Objective To study the biomechanical significance of hip resurfacing arthroplasty at the femoral side by finite element analysis.

目的 通过有限元分析探讨髋关节表面置换后股骨侧的生物力学意义。

This was unavoidable because the first implantation of current-generation resurfacing devices was performed only nine years ago.

这是不可避免的，因为当前这一代表面置换假体第一次应用仅仅在9年之前。

OBJECTIVE: To explore the stress distribution of the femur and prosthesis following hip resurfacing arthroplasty.

目的：观察人工髋关节表面置换术后股骨及假体的应力分布。
