查询词典 the maximum

Based on the distance of Kullback-Leibler, this paper give the exact definition of the maximum Kullback-Leibler distance between two different distribution functions and prove that this one has analytic properties such as symmetry, triangle inequality which is the same as the Euclidean distance. By the definition, the maximum Kullback-Leibler distance between some conventional distributions, such as two different binomial distributions, two different normal distributions are obtianed.

Worn surface morphology was examined with scanning electron microscopy, and wear volume was measured with a Talysurf 5P-120 topographer. Results show that CNTs, in mass concentration of 0.01%~0.1%, can greatly improve the antiwear ability of lubricating oil. With addition of CNTs, the maximum reduction of wear rate is about 57%, and scratches on the worn surfaces become slighter and more uniform. The maximum decrease of friction coefficient is about 15% with 0.025% CNTs additive at the load of 300 N. The antiwear mechanism has been discussed.

The fatigue test of CFRP bars was carried out at the different cyclic stress, choose the 70% ultimate tensile stress of CFRP bar as the maximum cyclic stress, under the cyclic ratios of R=0.5 （the minimum-to-maximum stress ratio） and R=0 and the fatigue behavior of CFRP bars was investigated.

The results showed the maximum cyclic stress of CFRP bar should be under 70 percent of ultimate tensile stress; when the maximum cyclic stress decrease 5 percent of ultimate tensile stress, the fatigue life of CFRP bars increase generally 10 times; with the decrease of cyclic ratios, the fatigue life of CFRP bars decrease heavily; for the brittleness, CFRP bar should possess a higher reserve of strength, the margin of safety against failure is a necessity; according to experimental cyclic stress-fatigue life curve, the fatigue behavior of CFRP bar is much better than the fatigue behavior of Q235 steel.

On strength computation,the finite element models of rotating mirror were established according to the real structure of the mirror,and the rotating three-faced beryllium mirror were analysed.Results display that the surface deformation magnitude of the mirror is approximately 0.334 6 μm,and the maximum stress is 0.204 GPa at 600 m/s of edge linear speeed.The regions of maximum stress are on the axial hole and symmetric to symmetrical planes of mirror body,and keep beelines to surfaces.On the modal analysis,the results show that the first and second modals of bending vibration exist around 3.4×105 r/min and 6.6×105 r/min,which appear binate and orthogonal respectively,and another modal belongs to the first torsional vibration that occurs by 5.13×105 r/min.

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。

For the purpose of environment protection and reasonable development of scale breeding, Juchao District in Anhui Province, which is situated by the middle of Chaohu Basin, was taken to be studied. The maximum waste load of farmland was estimated through the breeding numbers and respective excretive coefficients. By comparing the actual load of livestock manure with the maximum admissible load, environmental risk of actual breeding scale in each community was evaluated.
