For the inverse matrix is a very troublesome thing.

求距阵的逆是很麻烦的事。

Then we prove the isometrical identity and inversion formula of the solution of the wave equation.

然后，证明这个二阶波动方程的解具有反演公式及等距恒等式。

The one order differential model and convolutional model of impedance formula of amplitude versus offset inversion were established. Impedance inversion formula from AVO was derived based on Bayesian framework. Methods of using Huber function as prior model parameter distribution and covariance matrix from well log as constrains were developed. The P-wave impedance, S-wave impedance and density were calculated by the conjugate gradient algorithm.

为此建立了振幅随偏移距变化波阻抗反演公式的一阶差分模型及褶积模型，推导了基于贝叶斯理论的AVO波阻抗反演公式，给出了采用Huber分布作为模型参数的先验分布及测井数据的参数协方差矩阵作为约束条件的实现方法，并利用共轭梯度法计算了纵、横波阻抗及密度。

I hope you will chang the irascibility!

我希望距会改掉个的坏脾气！

For comparison, Iridium fragments are confined to altitudes between 582 km and 1,262 km.

相比之下，铱33卫星碎片则分布在距地面582公里至1262公里的高度之间。

That the location of the airport帕希姆happens to be in the center of Europe, from Hamburg, 120 km, Berlin 160 km, between the two major German cities have a sea port of iron supply and rail systems, but there is no air transport hub, Pa Fahim stop at the airport between the two cities, while Hamburg is Europe's second largest port, and the Baltic port of Rostock, Wismar, Lübeck circle at the airport, 100 km range, have a direct rail link, the multimodal transport is that it combines the advantages of.

庞玉良认为帕希姆机场的所在位置刚好是在欧洲中心，距汉堡120公里，柏林160公里，两个主要德国城市之间都有海、铁的货源的港口与铁路系统，但没有空运枢纽，帕希姆机场罢处于两城市之间，而汉堡又是欧洲第二大港口，而波罗的海港口罗斯托克、维斯玛、吕贝克在机场圈100公里范围之内，有铁路直接联系，这种多式联运结合是它的优势。

If for any〓,they are conjugate to each other in D if andonly if they are conjugate to each other in G then every virtual character of D is-stable and if〓is an irreducible character of G in b with height zero,the map〓is an isometry from〓onto〓.

若对任意〓，它们在D共轭的充要条件是它们在G中共轭，则D的每一个指标是-稳定的，且若x是G落在b中的高零不可约指标，则下面映射是从〓到〓的等距映射

下肢骨包括髋骨（由髂骨、耻骨、坐骨构成）、股骨、髌、胫骨、腓骨、跗骨七块（距骨、跟骨、舟骨、第一、二、三楔骨、骰骨）、跖骨五块和趾骨，它们分别组成髋关节、膝关节、踝关节、跗跖关节、跖趾关节和趾关节。

Due east of King's Cross, a bit less than a mile away in Islington, is Angel Station, on the Northern Line.

国王十字车站正东方，在距它略少于一英里的伊斯灵顿，是北线上的天使车站。

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

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
