查询词典 echo

In this thesis we propose an orthogonal polynomials adaptive filter and perform theoretical convergence analysis of residual echo power which proves its faster convergence rate owing to the reduced eigen spread of the input signal.

在传统上，多项式采用次方级数展开的形式；而在本篇论文中，为了提升非线性适应性滤波器的收敛速度我们使用正交多项式的非线性适应性滤波器。

Methods: 17 healthy volunteers underwent axial conventional DWI and DWI with fluid attenuated inversion recovery by use of the single shot echo planar diffusion weighted MR sequence in three orthogonal directions on 3.0T MR imager.

17名健康志愿者在3.0T MRI上行常规轴位DWI和FLAIR-DWI扫描，分别测量两侧半卵圆区、扣带回、丘脑及胼胝体膝部和压部的ADC值及DWI信号强度，同时测量基底节层面的DWI信号强度作为噪声，计算以上5个部位DWI图像的信噪比。

If you need structured data, an XML document would be output with an echo statement in just the same way, but the content-type of the output page basically must be set to text/xml .

如果您需要结构化数据， XML文件将输出的回波声明只是以同样的方式，但内容类型的输出网页基本上必须设置为文本/ XML的。

The authors talked about civic space structure evolution on four cities of Dalian, Shenyang, Changchun and Harbin, at city field scope and outspend, and also made a contrast between them from angles such as central city, city-region space echo and so on.

作者从中心城市的联系、城市与区域空间互动、区域产业协调发展等角度出发，运用区域经济学、城市地理学、经济地理学、城市与区域规划等相关学科理论，对大连、沈阳、长春和哈尔滨四城市在市域范围及更大尺度上的城市空间结构演进进行了比较研究。主要内容如下

The lingering echo of the dashing waters are a paean of praise to and an expression of love for China's landscape.

The lingering echo of the dash ing waters are a paean of praise to and an expression of love for China's landscape.

在人们耳际荡起滔滔势的余响，表达了对华夏河山的赞美和热爱。

Some of them with visual loss, optic papilledema and orbital mass. B-scan ultrasonography revealed a cyctic tumor and a strong echo spot with spontaneous movement. On CT scanning, found was a well-defined hyperdensity mass in which there was a low density area. On MRI, the signal intensity of T1WI of cystic fluid was low or moderate and of T2WI was high, while the signal intensity of T1WI and T2WI of surounding scar tissue was still low.

结果 22例有反复的眶内炎症史及占位性病变体征，如眼睑及结膜充血水肿，眼球突出，眼球运动受限；6例有视力下降和视乳头水肿，并扪及肿物。B超示占位性病变内有液性暗区及自发运动光斑；CT扫描示高密度块影中央部有低密度区；MRI检查示囊液信号强度T1WI为低或中信号，T2WI为高信号，其周围的纤维瘢痕组织T1WI和T2WI均为低信号。

Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population.

在人们的保护措施下，一度濒临灭绝的长尾小鹦鹉的数量有了增加。

An accelerated acoustic echo cancellation algorithm is proposed in this paper based on Parallel Subgradient Projection technique.

摘要该文在并行次梯度投影技术(Parallel Subgradient Projection，PSP)的基础上，提出一种加速回波抵消算法。

It supports the sound effects such as chorus, compression, distortion, echo, flange, gargle, parametric equalizer, reverberation.

它支持的声音效果，如：合唱，压缩，失真，回声，法兰，漱口，参数均衡器，混响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
