The results show that: the input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar; the stress distribution of the femur under external violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.

分析结果表明：股骨颈处的压力骨小梁和股骨距是重要的承载结构，临床医学治疗股骨颈骨折时，内固定物的放置应循压力骨小梁方向并尽量紧贴股骨距钻入；暴力作用时股骨上端的应力分布特点从生物力学的角度说明了老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

Seeral types of calcar replacement femoral components, as illustrated in Fig. 7-33 , are aailable for patients with loss of arying amounts of the proximal femur in lieu of the use of bone grafts.

如图7－33所示，几种带股骨距的股骨置换假体可用于股骨近端有不同程度骨缺损的病人，以替代骨移植。

However, the stress load alters in the proximal femur following THA, leading to "adaptable bone reconstruction", which is characterized by thin cortical bone, decreased bone density, and bone loss surrounding prosthesis, in particular calcar femorale.

但是全髋关节置换后股骨近端应力负荷会发生改变，导致股骨近端的所谓"适应性骨重建"，其特点是皮质骨变薄，骨密度下降，引起股骨近端假体周围，尤其是股骨距区骨丢失。

On the fracture section, three strain gauges were put above the pins of groups fixed with external fixator. The gauges were recorded when the femurs were loaded vertically. Results (1) The compressive trabeculae and femoral calcar in the femoral neck region are the main load-bearing construction. The contract of the abductor muscle can protect the hip joint. When the model femur was abducted in small degree (10-30°), the stress improved gradually with the abductor angle. But adduction of the model will gradually decrease the stress in that area. When external violence was put on it, the main stress distribution was on the upper femur, which was in the middle and lower part of the femoral neck and between greater trochanter and lesser trochanter.

同时在④⑤两组又应用电阻应变片贴于断端间的三枚斯氏针上方以测定钢针上的应力与应变结果(1)股骨颈处的压力骨小梁和股骨距是重要的承载结构；载荷的传导主要通过压力骨小梁和股骨距由股骨颈区传至股骨干的中下1/3处；外展肌力的收缩对髋关节有一定的保护作用；在小角度外展实验中（10-30°）股骨颈区的应力递增，超过30°时股骨颈区的应力又逐渐减小，但在内收实验中随角度增大股骨颈处应力呈递减趋势；当外界暴力作用时，应力主要集中在股骨上段，即股骨颈中下段和大小转子处及其之间。

METHODS: Measurement of palatal raphe area first three-dimensional reconstruction of images at up to nasion plane centerline, whichever was determined as a reference surface plane, selection one point on incisor cervix in this line, to measurement of the available palatal bone height; sagittal views were selected at 6 mm dorsally from the incisive canal. The available bone height was defined as the distance from the palatal baseline (lower cortical border of the palate) to the nasal cavity (upper cortical border of the nasal cavity).

先在三维重建图像上以鼻根为准确定面中线平面为参考平面，在此线上选择1个位于中切牙牙颈部的点，在其矢状位图像上，选取位于口腔内侧骨皮质上距切牙孔后缘6 mm处为标测点，通过此点向硬腭做垂线确定腭骨厚度，测量范围自口腔内腭部骨皮质外侧边缘至鼻腔侧骨皮质外侧边缘。

Results: Anterior talofibular ligament on axial plane, calcaneo fibular ligament on coronal and oblique axial planes, posterior talofibular ligament on all of four planes, cervical ligament on coronal and sagittal planes, interosseous talocalcaneal ligament on coronal, sagittal and oblique axial planes, lateral bundle of inferior extensor retinaculum on coronal and sagittal planes, medial and intermediate bundle on coronal planes, can be most clearly observed.

结果：距腓前韧带在轴位，跟腓韧带在冠状位和斜轴位，距腓后韧带在四个方位，颈韧带在冠状位和矢状位，距跟骨间韧带在冠状位、矢状位和斜轴位，伸肌下支持带浅束在冠状位和矢状位，中束和深束在冠状位，能清楚观察各韧带的形态和毗邻关系。

Results When the foot was in a relaxing position, the optimal position to observe anterior talofibular ligament with MRI was transverse orientation, to calcaneofibular ligament was transverse oblique, to posterior talofibular ligament and cervical ligament was coronal and to interosseous talocalcaneal ligament was sagittal orientation. The identifying signs of the ligaments were described.

结果 当足呈自然放松位时，距腓前韧带在横断位，跟腓韧带在斜横断位，距腓后韧带在冠状位，颈韧带在冠状位，距跟骨间韧带在矢状位断面上，为最佳观测方位，并提出了各韧带在断面上的辨认标志。

MAIN OUTCOME MEASURES: The palatal bone thickness and bone thickness density were measured at 6 mm dorsally from the incisive canal.

主要观察指标：口腔内侧骨皮质上距切牙孔后缘6 mm处腭中缝的骨厚度及骨密度。

In addition, finite element modeling and direct measurement of strains within proximal medial cement mantles hae demonstrated only slight increases in cement strain with the use of stems with enhanced offset.

另外，有限元模型分析及对近端内侧骨水泥套内侧应变的直接测量表明使用加长偏距的股骨柄对骨水泥的应变仅有轻微增加。

Ruyu Jiaquantian meng Ruins 2 years ago about "advanced Homo sapiens" fossils of human bones; Qian'an Zhaocun Village Ruins 40,000 years ago if the tooth's edge as the ancient ivory and human used to sew the late Paleolithic clothing of bone needles, bone cone; move posts MA solitary village unearthed bamboo with close ties to the state-owned "The Double" and "bo ding "; Qian'an Liao Dynasty unearthed in white, is a boutique Ancient.

如玉田孟家泉遗址出土距今2万年左右的&晚期智人&的人骨化石；迁安爪村遗址出土距今4万多年的若氏古棱齿象象牙及旧石器时代晚期人类用来缝制衣物的骨针、骨锥；迁安马哨村出土的与孤竹国有密切联系的&其簋&和&卜鼎&；迁安出土的辽代白瓷，堪称古瓷精品。

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。
