阶梯收费问题举例

阶梯收费问题与现实生活联系紧密,经常在各类试题中出现.现举例说明其解题策略.例1某市出租车的收费标准是:起步价为8元,起步里程3km(3km以内按起步价付费),后每千米收2元(不足1km按1km计算).小王乘出租车从甲地到乙地共付费16元,求甲地到乙地的距离.分析首先,要理解出租车车费如何分段累加计算,如图1:把总路程分割为两部分:起步里程3km(含3km以内)为第一部分,收起步价8元;超过3km的里程为第二部分,每千米收2元.设甲地到乙地的距离为xkm,第一部分3km,收起步价8元;第二部分(x-3)km,收2(x-3)元.根据题意得:2(x-3)+8=16,解得x=7,所以甲地到乙地…     

On Word-formation of China English Lexis

This paper introduces China English and China English lexis,and analyzes the four ways of the word-formation of China English lexis:transliteration,loan translation,loan-blend and coinage.The analysis can show that China English is used to express the language system in a special situation in China,and it has brought large number of new lexis and new vision into world Englishes,which has enhanced the expressive force of English.     

Application of land use regression for estimating concentrations of major outdoor air pollutants in Jinan, China

SO2, NO2, and PM10 are the major outdoor air pollutants in China, and most of the cities in China have regulatory monitoring sites for these three air pollutants. In this study, we developed a land use regression （LUR） model using regulatory monitoring data to predict the spatial distribution of air pollutant concentrations in Jinan, China. Traffic, land use and census data, and meteorological and physical conditions were included as candidate independent variables, and were tabulated for buffers of varying radii. SO2, NO2, and PM10 concentrations were most highly correlated with the area of industrial land within a buffer of 0.5 km （R2=0.34）, the distance from an expressway （R2=0.45）, and the area of residential land within a buffer of 1.5 km （R2=0.25）, respectively. Three multiple linear regression （MLR） equations were established based on the most significant variables （p〈0.05） for SO2, NO2, and PM10, and R2 values obtained were 0.617, 0.640, and 0.600, respectively. An LUR model can be applied to an area with complex terrain. The buffer radii of independent variables for SO2, NO2, and PM10 were chosen to be 0.5, 2, and 1.5 kin, respectively based on univariate models. Intercepts of MLR equations can reflect the background concentrations in a certain area, but in this study the intercept values seemed to be higher than background concentrations. Most of the cities in China have a network of regulatory monitoring sites. However, the number of sites has been limited by the level of financial support available. The results of this study could be helpful in promoting the application of LUR models for monitoring pollutants in Chinese cities.
