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。

Pear clone with low-chilling requirement 'SH-085' were planted in containers under shelter, after being grafted on bird pear rootstocks. Two soil water status treatments were undertaken at three different stages after entering short days. Sampling and defoliation were done respectively on Oct. 19, Nov. 3, Nov. 16 and Dec. 1. And then the defoliated plants were treated with high soil water content (-0.01 MPa~-0.05 MPa) to observe the growth and to analyse the accumulation of carbohydrates at various stages.

Critical C/Fe ratio as a new concept has been put forward in this paper, when the amount of carbon adding into pellet large than critical C/Fe ratio, it will results that the S% of DRI goes beyond the criterion so that EAF refuse to use it, when less than critical C/Fe ratio, it will accelerate reduction and desulphur.

文章根据热态DRI的再氧化机理，提出了一种利用半熔融密封料覆盖反应罐口的防再氧化理论，在还原温度时半熔融密封料熔化成液相，将罐口密封，反应罐冷却时，这层半熔融密封料凝固并和罐壁紧密结合，阻止氧化性气体的侵入，达到防氧化的目的。
