By age 50, almost everyone has significant disk degeneration.

Based on wave propagation feature, this paper analyses 3D seismic migration algorithms such as alternating direction implicit method, LU decomposition method, and inverse operator approach method. The result shows that the alternating direction implicit method is fast but causes distortion in wave field extrapolation and affects image accuracy; however LU decomposition and inverse operator approach methods are fast while holding circular symmetry of wave field, and are promising in oilfield exploration and development.

在波的传播特征分析基础上，对交替方向隐式法、LU分解法、逆算子逼近法等三维地震偏移算法进行了分析研究，结果表明，交替方向隐式法虽然快捷但是在波场外推中明显产生畸变并影响成像的准确性，而LU分解和逆算子逼近法是保持波场圆对称特征前提下的快速算法，在油田勘探开发中具有较好的应用前景。

As they did this, they scattered, climbing over the mountains of useless scrap and down into the amphitheatre, where they found themselves forming a huge circle in the middle.

当她们这么做的同时，她们散开来爬上由无用的废料形成的小山，再下到环形剧场，呈一个巨大的圆站在中央。

AVOID mentioning her amputation and the reasons therefor in the first meeting, if possible.

美国的天，也许比中国的蓝，但是，美国的月亮，和中国的一样圆。

In addition, the anal fin has a curvature that fits the round shape.

还有，尾鳍有一个弯曲度刚好适合鱼的圆型身体。

The load that uses fiber model law to analyse concrete of round CFRP- steel tube to control curved component part - in sectional deflection curve, analytic result and test result be identical are better and slant at safety.

采用纤维模型法分析圆CFRP-钢管混凝土压弯构件的荷载-中截面挠度曲线，分析结果和试验结果吻合较好且偏于平安。

We show that a 1-D signal and its derivative at different scales can be represented by one analytic function defined on the unit disc in the complex plane.

我们证明一个一维信号及其微分在所有尺度下可以用复平面上的单位圆上的解析函数来表示。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
