On a convex surface, the pressure is less than

在凸面上，底面压力变小，向心力与水的自重方向一致；在凹面上，底面压力变大，向心力与水的自重方向相反。

According to the results of stress calculation, provided the choosing basis for structure parameters of hydraulic cylinder and advanced a new cylinder bottom structure-oblique plane check ring concave groove.

对 10MN闭模挤压液压机卡环式液压缸进行有限元应力分析，根据分析结果，给出了液压缸缸底结构参数的选取依据，并在此基础上提出了一种斜面卡环凹槽新结构，有效解决了大型卡环式液压缸卡环凹槽的应力集中问

Devices in the test package include: a high-precision automated dimensional gauge designed for measuring the unique attributes of bottles, particularly threaded and crown finishes as well as weight and pushup; a pressure tester for performing buckle and bottom roll out tests; a dual-purpose tester that performs both fill point volume measurements and top-load tests; and a thickness gauge for high accuracy measurement of material distribution.

该成套测试仪器的装置包括：一种用于测量瓶子独特属性的高精度自动化尺寸测量仪器，特别是对螺纹瓶口和皇冠盖瓶口，以及重量和瓶子凹底的测量；一个用于进行凹凸和瓶底压平测试的压力测试器；一个进行灌装点容积测量和最大负载测试的双重目的测试器；一个高精度测量材料分布的测厚仪。

From the above observations, it was deduced fragmentation process of the shell, and concluded that fragmentation of the explosive shell with bottom concave will made as soon as it breaks away from gun muzzle resulted from overburn of material at the bottom co.

根据上述结果，推测了这发弹的破碎过程，并得出结论，这发底凹榴弹出炮口即发生破碎是由于底凹部材料过烧引起的。

A maths model according to anatomic measure in Transorbital Roof Craniotomy were established to compare with transorbital keyhole approach to frontal base meningioma and pituitary adenoma. We discovered that removing 1cm orbital roof bone will increase the instrument handle angle from 360 to 450(25%).

本文通过经眉弓锁孔去眶顶入路对前颅凹底脑膜瘤垂体瘤的手术治疗，从解剖测量数据建立几何数学模型，与传统眉弓入路进行比较发现去除1cm的眶顶骨质，在理论上手术器械的操作角度从360增加到450即增加25％。

Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.

新桥深凹露天矿边坡岩体的原位剪切试验、点载荷试验、室内模拟AMD作用试验表明：AMD蚀化后的石英砂岩，岩体层面间的抗剪强度和粘聚力减小的幅值约为13.2%~21.3%；层面间内摩擦角减小幅值在5.0%~7.5%之间；AMD一般影响垂直边坡体内部在60~100m范围内的岩体力学性质数值分析表明：AMD对边坡体的作用主要集中在弱化区域内，边坡体的底脚和AMD作用中心区域的剪切应力减少了52.0%和64.7%；(2)随着边坡体高度和距离的增加，远场爆炸应力波对边坡扰动幅值的增加趋势明显，边坡顶部和断层部位的响应突出，损伤效应明显；边坡底脚扰动幅值最小，临空面附近台阶的扰动幅值明显大于边坡体内部；(3)AMD与爆破荷载耦合作用后，边坡体内部的应力分布主要呈现出爆炸应力场的特征，AMD影响区域形成了一个剪切应力弱区。

Results: When the top shape of osteotomes was concave,displacement and tensile stress were the maximum at the maxillary sinus floor.

目前，在临床中，骨挤压器顶端形状分为凸形、平形和凹形3种，对于哪种形状的骨挤压器在窦底提升术中提升效率高，对窦底的损伤小，目前观点不一致。

According to AAR Manual,calculations are made respectively for the lateral forces applied on vehicles due to deviation of the coupler while the drawing point is in different positions(on the bogie and on the carbody) of the new type speed increased 90 t depressed center flat car ,so that basis is provided for determination of the overall scheme.

按照《AAR机务标准手册》，对新型提速90 t凹底平车的牵引点布置在不同位置(布置在转向架上和布置在车体上)时由于车钩的偏移而作用在车辆上的横向力分别进行了计算，为确定总体方案提供了依据。
