置换

Objective: To evaluate the effect of posterior cruciate ligament resection on the tibiofemoral joint gap and its clinical value in total knee replacement.

中文摘要：目的：通过研究全膝关节置换中后交叉韧带切除对于胫股间隙的影响来探讨其在全膝关节置换中的临床意义。

OBJECTIVE: To explore cervical adjacent zygapophyseal joint stress distribution following two level ADR and anterior cervical discectomy and fusion, so as to provide biomechanical reference for clinical application of two level ADR.

目的：观察轴向载荷对双节段颈椎人工椎间盘置换和前路椎间融合内固定对邻下位节段关节突关节内压力的影响，以期为双节段人工颈椎间盘置换的临床应用提供生物力学依据。

Or else, posterior approach is a better choice. As regard to patients who had both ankylosed hips and only one hip can be undergone total hip replacement, after the operation, the function of this hip is good, but the patient can't walk because of the influnce of the other hip, so that the Harris hip score is very low, often less than 70 points. But this didn't indicate that the function of the hip is poor. Due to that, we recommend that the Charnley hip score should be adopted under this condition.

对双侧强直患者，行单侧置换后，该髋关节良好，但受对侧或其他关节的影响，患者仍不能行走，Harris评分仍很低，在70分以下，但这并不能说明术侧髋关节功能不好，因此，对经济状况不良或身体状况差者，不能同时行双侧手术，单侧髋关节置换后功能评分将受影响，双侧髋关节强直的患者只行单侧手术后的评分不适合用Harris评分，而用Charnley评分较为合适。

Objective To explore changes in the height and width of the cervical intervertebral foramina of C6,7 before and after the C5,6 discetomy, the replacement or the anterior intervertebral fusion so as to provide the theoretical basis for the clinical practice.

目的 探讨C5、6人工椎间盘置换、椎间盘摘除、前路椎间融合内固定后对邻近下位椎间孔形态改变的影响，为临床应用颈人工椎间盘置换提供理论依据。

The Coordinated Multi-Queue Algorithm relieves this problem efficiently. CMQ algorithm classifies the blocks which often be accessed together as an access group, and replaces the blocks of an access group in bulk. CMQ algorithm homogenizes the cache hit-ratios of all the storage nodes caches, and improves the global cache hit-ratios of the cluster file system.

采用存储节点缓存协同置换算法CMQ(Coordinated Multi-Queue)把一些经常同时被访问的数据块归为一个访问组，并对访问组施行整体置换策略，使各存储节点缓存的命中率趋于均匀，从而提升并行文件系统存储节点缓存的整体命中率。

Material and Methods:unipolar hip replacement in 2 patients,bipolar hip replacement in 10 patients,total hip replacement in 6 patients,mean years of follow-up is 2years and 4months,applying with Harris score system to examine patients,while photoing hip X-ray on anteroposterior and lateral sites,.

材料与方法：对18例髋关节置换术后患者进行随访，其中髋关节置换单极2例，双极10例，全髋6例，其平均随访时间为2年4个月，应用公认的Harris髋部评分系统，在疼痛、功能、活动范围和畸形四个方面进行临床检查，同时行髋部正侧位拍片检查。

In addition, some patients chose to have a traditional total hip arthroplasty instead of a resurfacing arthroplasty.

此外，也有些患者愿意进行传统的全髋关节置换，而不是髋关节表面置换。

In addition, some patients chose to hae a traditional total hip arthroplasty instead of a resurfacing arthroplasty.

此外，也有些患者愿意进行传统的全髋关节置换，而不是髋关节表面置换。

Estimating calculation method of consistencycan be used to calculate bleach agent consistency in the saturation water of fiber cell wall.. The main cause of the reaction rate of displacement bleaching being faster than that of conventional bleaching is that the bleaching agent consistency in the saturation water of fiber cell wall, when bleach liquor mix with pulp by displacement way, is bigger than that of by conventional way.

浓度估算法可用于估算漂剂在纤维细胞壁饱和水分中的浓度，置换漂白比常规漂白反应速度快的主要原因在于漂液以置换方法与纸浆接触混合后纤维细胞壁饱和水分中漂剂的浓度比常规方法的高。

Result］four of 9 patients successfully retained their component at most recent follow up, without ongoing infection (mean 18 months, range 10～25 months).we have not draw the statistically significant factors that related to successful and failure,but the factors such as acute infection, surfacing replacement, immediate debrided after onset of symptoms, and the bacteria sensitive to antibiotic were relate to success.

由于病例数较少，本研究针对可能影响清创成功的因素未能得出有意义的统计学结果，但从结果看：急性感染清创容易成功，而慢性感染则很难获得成功；表皮葡萄球菌成功率较高，金黄色葡萄球菌均失败；表面膝置换成功率较高，而铰链膝置换则难以获得成功；出现症状后应该抓紧时间进行清创，延误的时间越长，成功的可能性越低。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
