置换

Replacement through a retrospective study of the mid-term therapeutic effect of the treatment of the patients. Methods FromJune 1997 to March 2000, a consecutive series of 152 (152 knees) cementless TKA performed in Hessing-Stiftung was studied.

Moreover, an improved upper bound on the average MAP decoding error probability of linear Slepian-Wolf systems for stationary memoryless sources is derived. Based on this improved bound, we analyze the performance of Slepian-Wolf systems based on LDPC codes and random permutations, and prove that under some conditions, all but diminishingly small proportion of LDPC encoders and permutations are good enough for the design of practical Slepian-Wolf systems when the coding length is very large.

然后，论文在相关平稳无记忆信源下推导出线性Slepian-Wolf系统平均MAP译码错误概率的一个改进上界，并在这一改进上界的基础上，分析了基于LDPC码和随机置换的Slepian-Wolf系统的性能，证明了在一定的条件下，当编码长度非常大时，几乎所有的LDPC编码器和置换对于实际Slepian-Wolf系统的设计都是足够好的。

Results BLASTn analysis revealed insertion or substitution of 18-38 nucleotides in the penA gene of gonococcal isolates with reduced ceftriaxone susceptibility.

将11株头孢曲松低敏和2株头孢曲松敏感的淋球菌penA基因全基因测序，通过BLASTn与BLASTx分析，研究penA基因的碱基插入和置换情况及PBP2中氨基酸插入和置换模式。

We identified reports of clinical trials that compared computed tomography-based and imageless naigated arthroplasty with conentional unicompartmental or total knee arthroplasty, regardless of the underlying condition or disease.

我们找出了以断层摄影术为基础的临床试验和不依赖影像的关节成形术导航的临床试验的比较报告，这些临床试验或者是常规分区膝关节表面置换术，或者是全膝关节表面置换术，但是未考虑患者潜在病情或疾病本身情况。

Is the Outcome After Single Segment Implantation Similar to Multisegmental Implantation?

单节段置换与多节段置换术后的结果是否相似？

Summary of Background Data. Multisegmental disc replacement procedures belong to the so-called "off- label" indications for disc replacement, which still lack evidence ofnoninferiority when compared with fusion procedures.

背景。多节段的腰椎人工椎间盘置换手术属于所谓的&无标签&的椎间盘置换指征，目前依然缺乏明显的优势，和腰椎融合技术相比。

the hip knee joint replaces the technique the deep phlebothrombosis, are cause the fibrin, the red blood cell under each kind of factor function as well as not the isometric blood platelet and the white blood cell in the vein the clustering process, after is the hip knee joint replaces the technique, most common complication.

髋膝关节置换术后的深静脉血栓形成，是在各种因素作用下导致纤维蛋白、红细胞以及不等量的血小板和白细胞在静脉内形成凝块的过程，是髋膝关节置换术后最常见的并发症。

The main objective of the dissertation was to improve and modify the experimental procedures of mouse nuclear transfer and pronuclear transplantation, respectively, and try to establish new possible methods for mouse cloning and pronuclear transplantation.

本论文的主要目的是改进和修改小鼠核移植和原核置换的实验程序，试图建立新的小鼠核移植和原核置换的可行方法。

It shows that mechanical activation makes the activity of iron increase sharply and enhanced its replacement reaction ability. Succeedingly, the recovery of copper and nickel is improved.

在铁粉置换法中，利用机械活化可以增强铁粉的活性，从而增大从溶液中置换铜镍的效果。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
