The right and left TMJ were removed from the animals, and all the specimens were observed. 3 days later, we could find that all TMJ components showed signs of injury. The synovial membrane was torn up and the cartilage of the condylar process and glenoid fossa was destructed.

伤后3天可出现关节滑膜撕裂、颞骨和髁突骨质破坏、关节腔内积血，关节盘以及关节附着的断裂等改变；7天后，关节积血少见。2周后可见关节内明显的破坏性改变，关节腔内还可有渗出液存在。

The females incubated at 33 , their ovarium has powerful cortex, the germinal epithlium produce oocyte, its medulla degenerate into ovarian cavity. During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of ovary increase in quantity, they disintegrate after sexual differentiation. There are a lot of big grana in cells of ovary before sexual differentiation, in the course of sexual differentiation the quantity of the big grana decrease, while small grana increase and peakafter sexual differentiation. The males incubation at 26 , cortices of their testes degenerate into a thin albuginea. Medulla are formed by testicular cords in which scatter spermatogonium.

33℃下孵化的小龟卵巢皮质发达，由原始生殖细胞产生卵原细胞，髓质退化成为卵巢腔，分化时卵巢细胞的超微结构显示线粒体和内质网的数量大大增加，它们在分化结束后解体，分化前细胞内有较多的大颗粒，在分化中大颗粒减少，小颗粒增多，在分化后小颗粒达到最多。26℃下孵化的小龟精巢皮质退化成为一层薄的白膜，髓质有许多睾丸管构成，管腔内有散落排列的精原细胞。

The EDFL is structured by insertion of three different short passive subring cav it ies, which serve as mode filters, into the main cav it y, and it is combined w it h a fiber Bragg grating, the MRCs resonator can make SLM lasing.

这种激光器通过在主环形腔中插入充当模式滤波器的三个长度不等的无源次级环形腔，并结合腔内光纤布拉格光栅形成多环形腔掺铒光纤激光器结构，多环形谐振腔可保证激光器的单纵模输出。

Results 12 cases tubal pregnancy were confirmed as well as 1 case of intra-uterine pregnancy. X-ray showed a localized dilation of fallopian tube , half-loop, ring- like or irregular shaped filling defect. In one case, cluster of grapes appearance of contrast medium could be seen at the frimbriate end of fallopian tube. Of the 12 cases of tubal pregnancy, 10 were successfully treated, the successful rate was 83%.

结果 诊断输卵管妊娠12例，宫内妊娠1例。X线表现为输卵管腔局限性膨大，腔内见半环状、环状或不规则充盈缺损11例，1例输卵管腔显影正常，但在输卵管伞端见对比剂呈葡萄串状集聚。12例经输卵管内注射MTX治疗，10例获得成功。

The flow distribution in micro premixing chamber is analyzed. The influence of the diameter of fuel inlets, the numbers of arc-shaped and straight micro-channel, the distance of second fuel inlets and the numbers of second fuel inlets on the uniformity of flow distribution and premixing characteristics are numerical investigated.

对微型预混腔内流场分布以及预混腔的燃料入口直径，旋、直流槽数量，二次燃料入口距离和二次燃料入口数量对微型预混腔内流动分布均匀性及混合特性的影响进行了数值研究。

Taking water-jacket of 226B diesel engine as the practical objective, the calculation in void fraction and the velocity filed of the water jacket were made.

最后以226B 型发动机水腔为工程应用对象，计算出了水腔内的空泡份额分布和水腔内的流度分布情况。

Inferior vena cava is the largest vein in human body , wider than the hepatic vein, so some researchers propose direct intrahepatic portacaval shunt to lead some portal blood flow directly into vena cava, hoping to obtain more stable bypass.

DIPS术是在肝内门静脉与肝后段下腔静脉之间建立肝内分流，将部分门静脉血液直接分流入粗大的下腔静脉，它扩大了介入性门腔分流的适应症，可使部分难以实施TIPS术的患者也能做介入性门腔分流，成为介入性门腔分流的新热点。

In addition, many studies of patients with AVN showed plenty of special characteristics,such as age distribution and bone quality.Objective:To study the geometric features of proximal femur for the Chinese AVN population,in order to prove the existence of special characteristic of proximal femur for the disease and then develop an AVN-specialized stem evaluated by a validated finite element analysis.Methods:1.The author investigated the standard X-ray data of 127 cases(179 hips) with definite diagnosis of AVN to provide anatomical references for this disease.At the same time,we conducted a meta-analysis of anatomical studies of normal proximal femur data,including the section of LT+20,LT,LT-20 and CFI to identify the potential difference between AVN and normal population.

方法1、通过研究AVN患者标准X线正、侧位片127例(179髋)，获得股骨近端的解剖学数据，利用荟萃分析的方法比较AVN患者股骨近段髓腔特征平面(LT+20，LT，LT-20)及CFI的改变与以往研究数据的差异，并利用创伤性FNF患者资料代替正常人股骨数据进一步比较髓腔前、后、内、外四条曲线段上的差异。2、通过结合现代CAD技术，将内、外、前、后曲线拟合到AVN柄的外形上，选用短柄假体设计，近段设计利用AVN患者骨髓腔CT相对应位置的断面进行修正，设计AVN人工股骨柄。3、计算机三维有限元分析：①使用CAD软件SolidWorks和有限元软件Ansys所建立的髋关节股骨侧假体置换后的三维有限元模型。
