普通话水平测试中“方言语调”的可操作性标准的研究

明确"方言语调"涵盖的基本范围,才能减少测试中误判的几率;掌握评分标准,才能保证评分不偏离等级特征。本文试图从两个方面探讨"方言语调"包括的基本范围和评分问题。

The Evaluation of the Sound Insulation of Partition in Expanded Frequency Range

This paper reports on an evaluation of airborne sound insulation in a wider frequency range then is used in classical measurements. For analyzing sound insulation was used frequency range from 50 Hz to 10 kHz via standard range I00 Hz to 3,15 kHz. For four constructions with different structure was measured sound reduction index depend on frequency and calculated Weighted sound reduction index according to EN ISO 717-1. Then the results were compared. The measurements were made for samples of construction with different sizes. The results of measurements show how the size of sample influence on measured sound insulation. This article could be useful for specialist of architect acoustic and all who interest in sound insulation.

A NEW HYBRID FORECASTING ALGORITHM AND ITS APPLICATION IN ECONOMIC ANALYSIS

There exists a great deal of periodic non-stationary processes in natural,social and eco- nomical phenomenon.It is very important to realize the dynamic analysis and real-time forecast within a period.In this letter,a wavelet-Kalman hybrid estimation and forecasting algorithm based on step-by-step filtering with the real-time and recursion property is put forward.It combines the advantages of Kalman filter and wavelet transform.Utilizing the information provided by multi- sensor effectively,this algorithm can realize not only real-time tracking and dynamic multi-step fore- casting within a period,but also the dynamic forecasting between periods,and it has a great value to the system decision-making.Simulation results show that this algorithm is valuable.

Clinical observation on filiform fire-needling plus continuous passive motion therapy for frozen shoulder

Objective:To observe the clinical efficacy of filiform fire-needling plus continuous passive motion(CPM)therapy for frozen shoulder.Methods:A total of 72 patients were randomized into an observation group and a control group by the random number table method,with 36 cases in each group.Patients in the control group received celecoxib capsule plus CPM,while those in the observation group received filiform fire-needling plus CPM.The whole course of treatment lasted for 2 weeks in both groups.The visual analog scale(VAS),Constant-Murley score(CMS)and range of motion of shoulder joint were measured for therapeutic efficacy evaluation.Results:The total effective rate was 91.7%in the observation group,higher than 72.2%in the control group,and the between-group comparison showed statistical significance(P<0.05).After treatment,the VAS scores in the two groups dropped significantly,the CMS as well as the range of motion including abduction,forward flexion and extension were all increased significantly,and the intra-group comparisons showed statistical significance(all P<0.05).The betweengroup comparisons showed the improvements in these items in the observation group were more significant than those in the control group(all P<0.05).Conclusion:Filiform fire-needling plus CPM can produce more significant efficacy than celecoxib capsule plus CPM for frozen shoulder;it can alleviate pain,improve shoulder function and restore joint range of motion in such patients.

Reconstructing provincial cropland area in eastern China during the early Yuan Dynasty(AD1271–1294)

Reconstructing historical land use and land cover change(LUCC) at the regional scale is an important component of global environmental change studies and of improving global historical land use datasets. By analyzing data in historical documents, including military-oriented cropland(hereafter M-cropland) area, the number of households engaged in M-cropland(hereafter M-household) reclamation, cropland area, and the number of households, we propose a conversion relationship between M-cropland area and cropland area reclaimed by each household. A provincial cropland area estimation method for the Yuan Dynasty is described and used to reconstruct the provincial cropland area for AD1290. Major findings are as follows.(1) Both the M-cropland and cropland areas of each household were high in the north and low in the south during the Yuan Dynasty, which resulted from different natural conditions and planting practices. Based on this observation, the government-allocated M-cropland reclamation area to each household was based on the cropland area reclaimed by each household.(2) The conversion relationship between M-cropland and cropland areas per household showed conversion coefficients of 1.23 and 0.65 for the south and north, respectively.(3) The cropland area in the entire study area in AD1290 was 535.4×106 mu(Chinese area unit, 1 mu=666.7 m^2), 57.8% in the north and 42.2% in the south. The fractional cropland areas for the entire study area, north, and south were 6.8%, 6.6%, and 7.1%, respectively and the per capita cropland areas for the whole study area, north, and south were 6.7, 15.6, and 4.1 mu, respectively.(4) Cropland was mainly distributed in the middle and lower reaches of the Yellow River(including the Fuli area), Huaihe River Basin(including Henan Province), and middle and lower reaches of the Yangtze River(including Jiangzhe, Jiangxi, and Huguang provinces).
