First, the color-image was preprocessed with grayscaling, smoothing. The vertical gradient components of the image were found using the vertical mask of Sobel operator. Then the candidate areas with sufficient amount of edges were determined by calculating the gradient of edges. After finding possible vehicle candidates, the proposed method measured the prominent vertical symmetry of candidate areas and verified all possible candidates, as symmetry is an important feature of vehicle. The proposed method also figured out the vertical axis of symmetry and the width of the candidate vehicle.

算法首先对图像进行灰度化、平滑去噪等预处理，使用Sobel算子垂直方向掩模计算图像感兴趣区域内的边缘梯度，确定候选区域；而后根据车辆图像垂直边缘具有对称性的特点，分析候选区域的对称性强弱，并计算其对称轴位置和车辆宽度。

Results:(1) All of HCC were irregular hyperdense in arterial phase companioned with mass and hyperdense tumor vessels.

结果 ：( 1)肝动脉期肿瘤实质出现密度高于肝实质的肿瘤血管和瘤区强化，门静脉期其密度迅速降低，至平衡期为低密度；( 2 )肿瘤边缘于肝动脉期和门静脉期均可见环行强化；( 3)转移性子灶仅在肝动脉期明显强化，门脉期全瘤密度迅速降至等密度；( 4)门静脉受累表现为肝内分支的边缘侵蚀、破坏、中断，或为不规则的充盈缺损。

Experiments on synthetic images with low signal-to-noise ratio images and nature images show good performmance and robust of the approach, especially it's capable to capture the discontinuous boundary and move snakes into boundary concavities.

对人工合成的低信噪比图像及自然图像的实验表明，本文方法性能良好，工作稳定，具有较强的处理边缘不连续及进入凹形边缘能力。

After convolving the image model with the edge detection operators of second derivative model, a plane fitting in the least squares sense is used to detect the zero crossing points as edge points.

使用二阶导数型边缘检测算子对图象模型进行卷积后，用均方误差最小的准则对卷积后的图象进行平面拟合，并求出零交点作为图象的边缘点。

The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach. The water is relatively deeper at the forming of most of platform marginal oolitic beach which is not transformed by the diagenesis of fresh water and mixed water and has poor reservoir properties. However, a part of oolitic beach formed under shallow water environment, and it is transformed by the diagenesis of fresh water and mixed water and well dolomitized, which can form excellent reservoir.

川西北下三叠统飞仙关组滩体分为台地边缘鲕粒滩和台地内点滩2种类型，多数台地边缘鲕粒滩形成时水体相对较深，未经大气淡水和混合水的成岩改造，储集性能较差，局部鲕粒滩形成时水体较浅，在经过大气淡水和混合水的成岩作用改造后，白云石化好，可形成储集性能极好的储集体；台地内点滩白云石化较好，储集性能也较好，但分布狭窄，厚度较薄，无规律可寻。

The bottom plate and annular plates of large storage tank s are more subject to corrosion.

大型储罐底板的边缘板在油罐腐蚀事故中占很大比例，有关储罐边缘板的防护问题是储罐防护的重要组成部分。

The draw ratio is the direct relationship between the draw punch and the blank edge—the greater the distance between the draw punch and the blank edge, the greater the resistance to flow, primarily because of the additional surface area of sheet metal clamped between the die face and the blank holder.

拉伸比直接体现在拉延凸模和板料边缘之间的关系--拉延凸模和板料边缘之间的距离越大，限制流动的阻力越大，主要是因为在压边圈和凹模表面间有额外金属板表面被夹紧。

Crustal original and crustal\|mantle original type are located at the Yinggehai basin of the northwest margin and controlled by the diapirs up-invasion and thick marine calcic sand shales. Volcano-mantle original type is most located at the Qiongdongnan basin of the northeast margin and the Pear River Delta. Furthermore, the accumulation and migration of CO2 and oil gas of these types of CO2 are controlled by the exhaustion of mantle magma and the transportation of discordogenic faults.

壳源型和壳幔混合型CO2富集于西北边缘莺歌海走滑伸展型盆地，受控于海相含钙砂泥岩与泥底辟热流体上侵活动的物理化学综合作用；火山幔源型CO2则主要展布于东北边缘琼东南及珠江口断陷裂谷盆地，其火山幔源岩浆脱排气活动与深大断裂导气输送作用的配置，控制了这种类型CO2的运聚乃至富集成藏过程。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
