Mothers. Although the sound persisted, the intrusiveness

Yvonne 因此而知所措，并请听众假装那高频的声音

The primary character feature curve by this method, called RPCGC (Ring-Projection Curve Gravity Center), has the invariant property with respect to rotation, and then the wavelet feature vectors from RPCGC has stability.

在字符信号f的多分辨率描述中，A〓f代表了信号的低频成份，反映了模式的基本形状，而D〓f代表了信号的高频成份，反映了模式的细节和噪声。

Detail image at each scale can be obtained by inverse transformation of wavelet coefficients of a noise image.

在含噪图像小波分解后，对每一尺度下三个高频子带的细节分量进行单层逆变换，得到该尺度下的细节图像。

This method was to avoid high frequency false wave and compress the effective signals and cause the decrease on inversion precision. The inversion formula was rederived.

这种做法在消除高频假波的同时会对有效信号进行一定的压制，造成反演精度的降低。

The numerical simulation demonstrates that when the intensity of the driving laser is over-saturated,the atom will be ionized rapidly during a few optical cycles,this will lead to a continuous multi-plateau structure in the cutoff region of the high harmonics spectrum from the neutral atom.

通过计算机数值模拟，发现当激光场的强度超过饱和光强时，原子将会在几个光周期内被迅速电离，使得原子的高次谐波谱在截止区呈现出平滑的多平台结构。同时，在高频波段离子产生的高次谐波的影响将变得十分显著。

Some authors proposed that the analyses of transfer cycles of high frequency base level and key surface correlation could be used to correlate isochronal strata.

在前人提出的高频基准面转换旋回分析和关键界面对比分析来确定等时性的基础上，以板中东油田板2油组水下冲积扇沉积为例，就湖盆内事件沉积的特点，提出可以结合洪泛面和事件沉积界面以及异旋回和自旋回来进行高分辨率层序地层的对比研究。

The results showed that the fracture toughness of the weld of HFW pipe was lowest.The value of absorbed energy of HFW weld was closely related to the heat treatment process.But the fracture toughness of fusion zone of submerged-arc welded jointer,its microstructure was coarse granular bainite,and was lower than the other locations of heat affected zone;and with the increasing of steel strength,the effect of welding heat cycles on the pipeline steel became stronger,and form coarse microstructure in fusion zone leading to decrease fracture toughness.

结果表明，高钢级管线钢高频焊接焊缝处的断裂韧性最低，其冲击功大小与热处理工艺密切相关；而埋弧焊接热影响区断裂韧性在熔合线处最低，其主要原因是此处的组织为粗大的粒状贝氏体，而且强度越高焊接热循环对管线钢的作用越强，在熔合线附近更容易产生粗大组织，使断裂韧性降低。
