However,authors still do not find the relevant references on convergence and symmetric problems of the semi-analytical solution.Based on the semi-analytical solution for Hamilton canonical equation theory,the formulations of the clamp and simply supported and symmetric boundary conditions on the Hamiltonian element are derived by the variational principle.Several numerical examples show that with increase of meshes,the convergence rate of the semi-analytical solution is faster than the convergent rate of traditional finite element method based on displacement.

①在厚度上没有任何位移和应力模式的假设，由于传递矩阵方法的引入，从理论上讲，不受板壳厚度或层合板壳层数的限制；②采用弹性力学的Hamilton正则方程半解析法，可以克服边界的局部化效应[8]；③由于在平面内或圆柱壳的曲面内采用了有限元法，所以一般的板壳问题不受结构侧面边界条件的限制，在复杂工程板壳问题上具有广泛的应用领域。

With the varieties of the different structural dimension and outer load, it will be real number and imaginary number.

为了在不过分增加壳板厚度或缩小肋骨间距的情况下保证稳定性，带中间支骨的环肋圆柱壳结构是

In this paper, we use FEM software ANSYS to simulate. Using FEM to evaluate the strength of pressure hull, the FEM model of outer covering and stiffeners can use shell element to establish, but it may waste much computing time to calculate. Therefore, in this paper, we can evaluate more easier by making use of the idea of effective-width, and considering the stiffener/plating combined moment of inertia.

本文采用有限元素分析软体ANSYS进行求解，在有限元素分析的模拟上，外壳与环肋均可用壳元素建立一实体模型来分析，但是在模型的建立上过於复杂，在解析上也需要更多的时间来计算，因此本文采用有效幅度的观念，考虑环肋与壳板间之组合惯性矩，将环肋部分取梁元素来模拟，如此一来可简化建立模型的困难度，且大大的缩短分析的时间。

Author has described the existing problems in process of design,fabrication and installation for 5 000 m3 PVC spherical tank;discussed the problems and its solution for analysis design;design change for spherical shell sector plate dimension ;weld gap exceeding the standard requirement etc.

The results show that the sandwich composites, applied to replace steel in submarine nonpressure hull, satisfy strength and rigidity requirements and its property of acoustical stealth is much better than that of steel strnctnre.

结果表明，潜艇非耐压结构的壳板采用夹层复合材料可以满足结构的力学要求，与钢结构相比声隐身能力大大提高。

The δ^34S values of ore minerals vary slightly from -3.1‰ to +0.7‰ with an average value of -1.1‰ and the δ^34S values of the ore-bearing porphyries are -1.4‰ and -1.5‰, indicating that sulfur is mainly derived from the magma of porphyry.

雪鸡坪铜矿S，Pb同位素组成共同指示成矿物质主要来自于深部岩浆，这种岩浆可能主要起源于俯冲洋壳板片的部分熔融并受到少量地壳物质的混染。

It is likely that the floor of the central nave was made up of one mosaic carpet. In the field were white flowers with twenty four petals with black lance-shaped leaves and red and black crosses, all on a red background. Especially suited for covering large areas, this design is called "shell-panel" by the archaeologists. It was used again in other places.

中殿的地板像铺了一条马赛克地毯，以红色为背景，有24片花瓣的小白花、黑色长矛形枼子以及红黑交错的十字架呈现其上，这样的设计适合面积较大的区块，考古学家称之为「壳板」，它也被使用在其他地方。

While the ship's draft being 5 ft forward and 25 ft aft, the both side shell plating at bow and bulbous bow all out of water were inspected and found in normal condition.

当该轮前吃水为 5 呎及后吃水为 23 呎时，船首两舷壳板和球鼻首均露出水面进行检查并发现正常。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
