叠

I used to have piles of MP3 files clogging up my computer hard drive.

我以前叠叠堵塞了我MP3音乐电脑硬盘。

Weak formulation of equilibrium equations including boundary conditions of laminated cylindrical shell is presented, thermal stresses mixed equation of closed continuous cylindrical shell is established.

建立了弹性力学基本方程的弱形式，从而得到叠层连续柱壳混合状态方程和边界条件放在一起的算子方程，扩大了求解的空间，给出了叠层连续闭口柱壳在热荷载和机械荷载作用下的解析解。

Experiment proved that the method based on phase congruency is the one that is invariant to illumination and magnification, robust to noise.

对要匹配的两幅图像，先计算它们的相位叠合，把它们的相位叠合映射成256个灰度级，在这一对新图像上尝试FMI-SPOMF算法，结果比较满意。

At present, the main approach for seismic data imaging is the prestack Kirchhoff time migration, however, violent variation of surface elevation makes the datum plane selection of prestack time migration very difficult.

目前该类地区地震勘探中主要的成像手段依然是Kirchhoff叠前时间偏移。但地表高程的剧烈变化使叠前时间偏移的基准面很难选择。

So far the pattern of seismic prestack depth migration is the same as it abroad. Before the work of velocity building the original seismic data must be corrected on a datum plane, and then to make the prestack depth migration work.

目前我国叠前深度偏移的研究方向与国外基本一致，特别是在目前油田的实际勘探中，大多套用国外的模式，一般都是对原始资料校正在一个基准面后，然后开展叠前深度偏移工作。

The normal graded type development mainly in microfacies of underwater distributary channel. The reverse graded type development mainly in microfacies of debouch bar or subaqueous crevasse splay, The homogeneous type development mainly in microfacies of distal bar, interdistributary bay, subsea natural barrier, prodelta et al.

正粒序型剖面结构主要出现在水下分流河道微相；逆粒序型剖面结构主要出现在河口砂坝、水下决口扇微相中；无粒序均一型剖面结构主要出现在远砂坝、分流间湾、水下天然堤、前三角洲等沉积微相中；复合粒序型剖面结构主要出现在叠置水下分流河道和叠置河口砂坝微相以及水下分流河道与河口坝的组合相序。

Additionally, the hinge will point north, and the diptych will be angled so the gnomon is parallel to the Earth's axis of rotation. At solar noon, sunrise and sunset, the latitude adjustment of the diptych can't affect the time of either sundial, but at 9am and 3pm, each degree of latitude error (from holding the sundial at the wrong angle) creates four minutes of difference between the two faces.

另外，当绞链朝向北方，摺叠式日晷被旋转了一个角度，晷针才能与地球的自转轴平行，则当正午、日出与日落时，摺叠式日晷的时间不会受到纬度改变的影响，但是在早上9点和下午3点，纬度每偏差1度，在两个晷面上的时间便会相差4分钟(肇因於日晷在错误的纬度上)。

Based on geological mapping and field observations, we conclude that there occurs a sedimentary interruption between the Middle and Upper Permian in the northern Qinghai-Tibet Plateau, which is represented by disconformity and angular unconformity.

通过对1999年以来在青藏高原北部空白区开展的1/25万区域地质调查成果等资料的分析，结合大量的野外观察，发现中、晚二叠世之间普遍存在着沉积间断，表现为地层之间的不整合或假整合以及晚二叠世地层的大量缺失。

What about stacked exposure? If we want to talk about origins, it began as a mistake in photographic exposure that eventually became a widely used technique. It is just like today's topic and exhibition; every time I have a discussion with an artist it is an exposure, and when there are more discussions, it becomes a double or multiple exposure, talking, chatting, laughing, moving on.

叠影？如果真的说清楚来源，是影像中一次失误的曝光形式，刚开始是错误，后来却成为精巧的技术被摄影界广泛使用，就像我们今天谈的话题和这个展览，每一次和艺术家的讨论就象曝光，都有几次以上的叠影，谈。

In order to apply and popularize this technology in our country, on the basis of having received researches, this project has carried out some theory analysis and developed a double-faced stack mold, which can easily be turned into a single-face mold according to production task.

为了实现这项技术在国内的应用和推广，本课题在总结国内外研究成果的基础上，通过叠式热流道模塑的理论分析，研制了一副可由单层冷流道模具拓展成为双层叠式热流道的模具。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
