Results? 6 cases in X-ray film revealed round or oval stones in areatus distribution in the areas of renal papillae and medulla. 3 cases of IVP revealed cystic or hair-brushed dilation. 5cases in B-ultrasound revealed little anechoic area and strong echo light spot in radial distribution with acoustic shadow. Unenhanced CT of 6 cases revealed spotted or areatus stones surrounding minor renal calices with collecting tube system dilation and enhanced CT showed artifacts of stones magnification because of the collection of contrast medium around the stones. Conclusion?

结果 X线平片检查6例，表现为肾乳头、髓质区见簇状排列的圆形、椭圆形致密影；IVP检查3例，显示肾集合管囊状、刷子状扩张；B超检查5例见肾髓质内呈放射状分布的小无回声区和强回声光点，其后方伴有声影；CT检查6例，平扫呈环绕肾小盏分布的点状或簇状钙化灶，集合管囊状扩张，增强后因钙化周围的集合管内造影剂聚集，造成钙化影增大的假象。

As I arrive, the din of chinking glasses and smoke-scratched voices dies down at the imperious strum of acoustic guitars, and seven men launch into an up-tempo, flamenco-style ballad.

当我到那里的时候，玻璃酒杯碰撞的叮当声和烟火的刮擦声已经湮没在非电吉他的弹奏之中，七个男子开始演奏一首急促的弗拉门戈风格的民歌。

Indeed,"Luminosa" boasts choral numbers arranged by Prizeman from a surprising variety of sources, including Saint-Saens'"Carnival of the Animals," Beethoven's Seventh Symphony, Pachelbel's "Canon," and Debussy's "Clair de Lune." Set to Latin words and recorded in an echoey acoustic style, the results have a churchy feel without being doctrinal.

的确，luminosa专辑中包括了很多出色合唱歌曲，是罗伯特从众多的音乐类型中选取出来的，包括Saint-Saens'&Carnival of the Animals，&贝多芬的第七交响曲，巴夏贝尔的圣颂和德彪西的月光，以拉丁文和回响式的音响风格编奏，因此演唱具有教堂的氛围，却不刻板。

Cogging torque is one of the most important parameters of PM motors,which causes torque ripple,vibration and acoustic noise.

齿槽转矩是永磁电机最重要的参数之一，它的存在会造成电机的转矩波动、振动和噪声。

In this paper,by numerical calculation, the effect of gas saturation on dispersion of model waves,excited spectrum of compressional wave and shear wave and full wave of acoustic logs in cased boreholl are discussed.

通过数值计算讨论了气体饱和度对声测井曲线的模式波的频散特性、纵波和横波的激发特性、全波波形的影响。

The system uses a special acoustic emission sensors, combined with the DSP card as a dedicated hardware platform, through UBS2.0 extended to PC, In the environment of the Windows operating system ,using software programming method to configurate USB 2.0 bus ,then to operate the hard platform, Achieved a high sampling rate data acquisition system of Cavitation signal.

该系统采用特殊的声发射传感器，结合以DSP为核心的预处理卡作为专用硬件平台，通过UBS2.0扩展到上位机上，在视窗操作系统环境下使用软件编程的方法，以微机作为控制单元经USB2.0总线对硬件平台进行配置和操作，实现了对气蚀状态信号的高采样率的数据采集。

In order to decrease the error rate of speech recognition, speaker adaptation techniques are often used to adjust speaker-dependent acoustic models. MLLR (Maximum Likelihood Linear Regression) and MAP are two of the most popular techniques in recent years. MLLR uses the technique of regression trees. It calculates the transform matrix for each leaf node of the tree. This makes it possible to use fewer sentences to decrease the error rate of HMM-based speech recognition. However, while we examined the recognition result, we found that although the overall error rate decreased, but the error rate of certain confusable phones was higher. In order to solve this problem, we propose the use MPE (Minimum Phone Error Discriminative Training) to solve this problem.

在语音辨识技术的实际应用上，语者调适技术常被用做调整语者无关之声学模型，使其对於特定语者之辨识率有所提升，常见的语者调适技术有最大化相似度线性回归（Maximum Likelihood Linear Regression），其精神在於透过对语音辨识模型相近的mixture做群聚，再对各个群聚做调整，以期能达到利用少量语料，提升辨识率的目的，但其缺点为，在发音上相近的模型，其mixture原本就极为近似，若再分类为同一群聚做调整，容易因为使用者的发音习惯，而使模型偏向ㄓ或ㄗ，因此虽然整体的辨识率获得提升，但却造成混淆音的错误率上升。
