洗碗机用液体洗涤剂的研制

研究了二元表面活性剂混合体系的泡沫、表面张力、cmc及浊点等性能，并据此进行了复合配方试验，添加自制复合钙皂分散剂和其他助剂，研制出了一种去污力高、起泡力低并适用于家用洗碗机循环喷洗用的液体洗涤剂。该剂为碱性水基清洗剂，不含强酸、强碱和磷助剂等成分，可用于中温（30℃－40℃）洗涤，能有效去除碗与碟等餐具硬表面的油污，对人、畜无毒，洗涤排水合格。

IBI and CA Model based Extraction of Urban Built\|up Areaand Its Application：A Case Study in Shanghai

At present,the automatic extraction of urban built\|up area is still a problem.Taking Shanghai city as an example,this research uses the binary image,which was derived from an IBI(index\|based built\|up index)image,as the geographical cellular automaton initial input data.This was then imported to the extended cellular automata model for further processing.After a series of processing such as thresholding,corrosion and connectivity test,the urban built\|up area was simulated and can be extracted.Based on this method,the urban built\|up area of Shanghai in five different years between 1987 and 2015 was extracted using multi\|temporal Landsat images of Shanghai.In addition,the urban growth intensity index,the concentric buffers analysis and radar chart analysis were calculated and used to analysis spatiotemporal pattern of Shanghai urban expansion in the 28 study years.The result shows that the built\|up area of Shanghai was expanded from 195 km² in 1987 to 1759 km² in 2015,which is eight times as large as that in 1987.In the period between 1987 and 2002,the urban built\|up area expanded mainly along the North\|South axis of the Huangpu River.However,after 2002 the expansion rate was increased more quickly,and the direction of the expansion was shifted to an east to west direction.Generally speaking,Shanghai has experienced a rapid urban expansion in the recent three decades.

Social diversity and construction era of neighborhoods with traditional design features: Portland and Atlanta compared

This paper compares neighborhoods with more traditional features in two very different cities. As expected, in Portland the majority are socially diverse and in Atlanta they are low‐income. However, in both cities about a quarter are high‐income. In Atlanta the latter are located in older neighborhoods, whereas in Portland they are also in areas combining newer and older housing. A return to valuing a more traditional urbanism may explain the signs of revitalized central cities in both places. Our findings, however, indicate it may be accompanied by the relocation of low‐income neighborhoods to areas where activities are not readily accessible.
