By adopting the strategy that the different components of the residuals and the noise are approximated by uncorrelated random variables after the SIC,the complexity of the algorithm can be greatly reduced as the matrix inversion for MMSE is not necessary.

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。

Excellent Flow Control- The eccentrically mounted disc design provides an approximately linear flow characteristic and can be used for on/off or throttling control applications through 90 degrees of disc rotation.

良好的流量控制，偏心式光盘的设计提供了近似线性流量特性，可用于开/关或节流，通过90度旋转的光盘控制应用。

Each segment of line current can be approximated as a Hertzian dipole if each segment is much smaller then a wave length.

因此任意线电流在三度空间之三维向量电磁场即可以赫芝电偶极完整之远场及近场近似合成之。

The experimental results indicated that the longer the po uring intervallic time of the two kinds of molten metal and the higher the heigh t of the molten iron to pour into the tip of dipper teeth , the narrower its tran sitional zone will be, on the contrary, the wider its transitional zone will be.

用不同粘度的流体通过水力模拟的方法近似地描述了双金属斗齿过渡区的混合状态。试验结果表明：两种液体浇注的间隔时间越长，先浇入的铁液液面越高，过渡区越窄；反之，过渡区越宽。生产中为了保证过渡区双金属的结合质量，应控制较高的铁液液面高度及一定的双液间隔时间

We have considered an approximating two-dimension Muskat model next, and gotten the existence and uniqueness of its local solution.

作为解决多维非等粘度的Muskat问题的第一步，还证明了一个二维Muskat问题的近似模型局部解的存在唯一性和正则性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
