This study investigated the impact of important environmental variables （i.e., wind speed, solar radiation and cloud cover） on urban heating. Meteorological parameters for fifteen years （from 1990 to 2005）, collected at a well developed and densely populated commercial area （Tsim Sha Tsui, Hong Kong）, were analyzed in details. Urban heat island intensity （UHII）, a well known indicator of urban heating, has been determined as the spatially averaged air-temperature difference between Tsim Sha Tsui and Ta Kwu Ling （a thinly populated rural area with lush vegetation）. Results showed that the UHII and cloud cover have increased by around 9.3% and 4%, respectively, whereas the wind speed and solar radiation have decreased by around 24% and 8.5%, respectively. The month of December experienced the highest UHII （10.2℃） but the lowest wind speed （2.6 m/sec） and cloud cover （3.8 oktas）. Conversely, the month of April observed the highest increases in the UHII （over 100%） and the highest decreases in wind speed （over 40 %） over fifteen years. Notably, the increases in the UHII and reductions in the wind speed were the highest during the night-time and early morning. Conversely, the intensity of solar radiation reduced while the intensity of urban cool island （UCII） increased during solar noon-time. Results demonstrated strong negative correlation between the UHII and wind speed （coefficient of determination, R^2 = 0.8） but no negative correlation between UCII and solar radiation attenuation. A possible negative correlation between UHII and cloud cover was investigated but could not be substantiated.

因应能源与环保等要求,润滑领域的绿色水基润滑剂得到越来越多的关注。虽然水基润滑符合可持续发展的要求,但它具有承载能力低和易腐蚀等缺点。因此,需要选择性能优异的添加剂以改善其润滑性能。聚醚类添加剂是水溶性聚合物基础添加剂,在大多数时候,在不同的润滑状态下均能够通过形成稳定的具有吸附和承载能力的薄层膜以改善润滑性能。本文选择两种无规则共聚醚:丙二醇无规共聚醚（propylene glycol polyether,PG＿PPE）以及十二醇无规共聚醚（propylene glycol copolymer ether,PG＿CPE）作为水基润滑剂的润滑剂,制备了不同浓度的PG＿PPE和PG＿CPE润滑剂,并对这两种水进行了一系列摩擦学性能测试和分析。实验结果表明,在10%,15%和20%时,PG＿PPE具有比PG＿CPE更好的摩擦系数性能。采用MRS四球测试仪分别对添加PG＿PPE和PG＿CPE的水溶液的摩擦/磨损性能进行比较,实验结果表明相比于PG＿CPE水溶液,PG＿PPE水溶液具有更为良好的抗摩擦性和抗磨损性能,并且比较稳定。然后,使用纳米级膜厚测量仪（NGY-6）研究了PG＿PPE和PG＿CPE水溶液在10N和30N下的成膜性能。结果显示,PG＿PPE和PG＿CPE的加入大大提高了纯水的成膜能力,随着一定质量分数内溶液的增加,膜厚逐渐增加。可见PG＿PPE和PG＿CPE是一种很有前途的水基润滑剂添加剂。
