凹陷的

e-PTFE was implanted into the pitting area after subcuntaneous disjunction. Results: 15 cases were followed for about 3 and 6 momths after implant of e-PTFE, including cases with saddle nose, pitting deformity of orbit, congenital lip cleft with depressed soft tissue around pyriform opening, parbial defect of helix. In these cases, satisfaction rate is evaluated as high as 97.9%, unexpected tissue response was not shown in this clinical trail.Conclusion: Depended on this clinical trail, we believe local e-PTFE manufactured by Shanghai Suo-kang Medical Implants Co., Ltd.

由于e-PTFE的组织相容性好，在80年代初期一些发达国家已经应用于整形美容外科[1]，尤其应用于隆鼻术、面部凹陷畸形的整复、唇线增高、唇加厚、鼻唇沟过深的整形美容术、耳廓缺损等手术中，学者们认为e-PTFE排斥反应的发生率低，弹性和硬度与软组织相似，周围组织细胞能够长期进入移植物内，不形成纤维囊，在整形美容外科领域有重要的应用价值。

Objective: Through comprehensive treatment of the loose skin, muscle, lower eyelid septum and protruding orbital fat in the aged, this kind of operation can correct them and meantime correct the sunken deformity of semilunar curve on the area of oculonasal groove and infraorbital marginalis in some patients.

目的：通过对老化和松弛的眼睑皮肤、肌肉、眶隔筋膜的矫正及眶脂膨出的综合处理，达到矫正睑袋膨出畸形、下睑皮肤皱纹、局部臃肿以及部分求医者显现的眼鼻沟区或眶下沟区的下睑半月弧凹陷畸形。

In this area, the evolution history of the main faults including Zhen①fault, Zhen②fault and Zhen②′fault is burring. Through the analysis of structural evolution and quantitative research of fault activity, the development history of the three main faults is verified. It also could be supported by structural physical simulation.

南部断阶带是高邮凹陷南部的一个二级构造单元，长期以来真①、真②及真②′等主干断层的发育历史模糊不清，本论文通过对构造演化的分析及对断层活动的定量研究重新厘定了三条主干断层的发育历史，并利用构造物理模拟实验对其进行了验证。

Methods: A little improvement was made on the management of orbital septum and septal fat while doing the general lower eyelid blepharoplasty. Separate the plane between them. Orbicularis oculi and orbital septum to the infraorbital marginalis, incise the orbital septum transversely, then sewing up the orbital fat onto the periosteum of the infraorbital marginaslis in order to fill up and correct the sunken deformity of this area.

在进行常规的睑袋整复术同时，对眶隔和眶脂的处理作适当的改进，在眼轮匝肌下平面分离到眶下缘，横向切开下睑眶隔筋膜，将眶脂缝合在眶缘的骨膜上，填充和纠正该区域的凹陷畸形。

There should, of course, be a normal, gentle hollowing in the lumbar region (it's called the lordotic curve) but exaggerating this will cause a painful "pinching" in the lower back.

当然，在腰部必须有一个正常的、和缓的凹陷，但太夸张的弧度会造成在背部的下端有种疼痛的&集聚&。

It was used to talculate the abnormal gas concentration of Qingshankou Formation's uncompacted mudstone in Sanzhao depression , Songliao Basin.

利用异常孔隙流体压力和异常温度建立了欠压实泥质源岩异常含气浓度的计算公式，并将其应用于松辽盆地三肇凹陷青山口组泥质源岩异常含气浓度的计算中，结果表明该区青山口组泥岩具有0.5～0.8m3／m3的异常含气浓度，对下伏扶、扬油层中的扩散相天然气具有强的封闭能力。

The zonality of abnormal pressure is closely correspondent to the breakthrough pressure (or pressure preservative ability) of mudstones in the Dongying Sag. The breakthrough pressures and formation fluid pressure coefficients rise with increasing depth. The preservation of isolated mudstone intervals is also important to the abnormal pressure formation.

东营凹陷异常压力的分带性与泥岩的突破压力具有明显的对应关系，随着深度增加，泥岩突破压力及地层流体压力系数均增大，泥岩封隔层对流体压力的保存也是形成异常压力的重要条件。

In order to overcome the problems of traditional snake associated with poor convergence to boundary concavities and sensitive initialization,gradient vector flow based on deformable models is presented to segment tumor region.

为了克服传统的蛇形算法不能收敛于边缘凹陷处以及对蛇的初始化过于敏感的缺点，本文提出用基于可变形模型的梯度矢量流方法提取乳腺X光片中的肿瘤区域。

The proposed method can detect certain object boundaries, for which the original method is not applicable. E.g. it can automatically detect interior and exterior contours of an object and edges of multi-objects, starting with only one initial curve whose position is anywhere in the image. Moreover, active contours can move into boundary concavities and perform better in the presence of weak boundaries.

它能够解决原方法所不能解决的一些图像分割问题，例如，能够从任意选取的一条初始曲线出发自动检测目标物体的内外轮廓，检测多目标物体以及深度凹陷区域的边缘，并能较好地提取目标物体的弱边界。

The active contour model is a powerful image segmentation method for representing image contour, but it has three severe difficulties. First, active contour model highly depends on its initial position. Second, active contour model lacks the ability to handle boundary concavities.

动态轮廓模型(active contour model； ACM)是一种功效强大的影像分割描绘方法，但却具有三个严重的缺点：第一、此模型非常依赖待描绘图形的起始位置，第二、此模型缺乏进入图形凹陷处的能力，第三、此模型有停滞在局部能量极小值的倾向。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
