This paper presents the methods to improve the performance of mispronunciation detection at syllable level for Mandarin Chinese from two aspects: introducing the speaker adaptive training and the selective maximum likelihood linear regression to get a better acoustic statistical model, and proposing speaker normalization backend because of the limited information and the different rating level for the different pronunciation level.

该文一方面为了获得对于发音错误检测更好的声学模型，引入了说话人自适应训练和选择性最大似然线性回归技术；另一方面，由于字发音检错中存在严重的信息量不足问题和专家对于不同水平说话人的评价标注不一样，在后端上加入了话者得分归一化技术。

Using this theory, the flame structure of gas explosion in a horizontal pipe were studied, and the results show that: the gas explosion flame in a horizontal pipe is much thicker than that calculated from the former explosion theory, the intermediate products in the flame region are in separated state between the higher and lower level, and the cohesive force of the luminous body at lower level is bigger than that of the nonluminous body at higher level, there is a negative pressure region in the flame, and the flame splits easily in its propagating process.

结果表明，a水平管道内瓦斯爆炸传播火焰的厚度比以往理论计算得到的厚度大得多；b火焰区内爆炸中间产物呈上下分离状态，下部明亮发光体的内聚力比上部非发光体的内聚力高；c在火焰区内会出现负压现象；d火焰在传播过程中会发生断裂现象。

Using the seale separation method, the meso-scale structure of Mcc occ- ured near the Delta Area of the Pearl River is studied. It is shown that there is a meso-scale cyclonic circulation at 1000 hpa level and a meso-scale anticyclon at 200 hpa level associated with the Mcc. The axis of the Meso-scale cyclone center tilts northwestward with height, stretching up to 400 hpa level.

用滤波方法分析了一例发生在珠江口附近地区的Mcc的中尺度结构，结果表明，在对流层下部有中尺度的气旋性涡旋与Mcc相应，涡旋的中心轴线随高度向西北方向倾斜，在地面涡旋的上方200hPa层上，是一中尺度的反气旋性涡旋，中尺度的辐合中心和上升运动中心偏于Mcc的西部，扰动温度场也是非对称的，在对流层上部没有中尺度的暖高压。

The algorithm combines the simulated annealing algorithm with the ratio-cut idea to ascertain the level of the multi-level multi-way partitioning and considers the number of cut lines while partitions CLB into cluster, then performs a k-way optimization without changing the level, so as to achieve a better partition result and improve the usage in HFPGA, then optimize the FPGA performance.

该算法将模拟退火算法与ratio-cut思想结合，确定多层多划分的规模后，在不影响规模的情况下进行多分优化，实现更好的划分结果，从而提高FPGA芯片的利用率，进而优化整个芯片的性能。

New land-level in accordance with the comprehensive category, commercial, residential and industrial categories identified four categories, identified only comprehensive than the original one-level type of land-level is more accurate and scientific.

新的土地级别按照综合类，商业，住宅和工业类确定了4个类别，确定只有全面的比原来的1级类型的土地级别是更准确，更科学。

In the model which has one product, the first level is a multi-goal programming, the decision-making variable is treaty tanff ,the second level is a nonlinear programming and the optimum tariff will he decided, the third level is a game, the industries decide the sale in domestic market and quantity of export by competing.

在单产品模型中，上层是多目标规划问题，通过谈判决策谈判关税；中层为一个非线性规划问题，决策国家的最优关税；下层为一个博弈问题，通过产业间的竞争决策内销量和出口量。

Accountant the environment may divide into three levels approximately: First, productive forces level; second, economic basis level; third, overtop structure level.

In contrast, DBA/2 mice from re-infected with PbANKA showed the high level of parasitemia and the same as that of primary infection; the level of IFN-γ in spleen cell super natants significantly increased on day 4 pi compared with control group (P.01); however, the level of specific IgG in serum didn't obviously elevated (P.01), and all mice died.

相比，PbANKA再感染小鼠出现高水平的原虫血症，与其初次感染水平柯近，再感染后第4d脾细胞培养上清中IFN-γ水平出现明显升高(P.01)，而血清中特异性的IgG抗体水平却无明显变化，与正常小鼠水平接近，小鼠全部死亡。
