【正文】 on of Changning Road and Gubei Road for people to enjoy the view of the creek and a 3km plastic runway on both sides of Changning Road, which attracts people of all ages, Chinese and expat. Jogging on the two sides gives a different feeling because the north side is next to the creek, and the south side is adjacent to the residential highrises, which is like jogging in the jungle, says Xiao Xu, a 27yearold woman who lives nearby. The riverside used to be pletely different. Dozens of textile mills, chemical plants and machine manufacturing factories were set up along the creek in the 1920s. They brought industrialization but also pollution. From the 1930s the creek could no longer be used as a source for tap water, and no living fish or shrimp could be found. Suzhou Creek in my memory is dark and smelly. I used to go to the riverbank to watch the sewage disposal running out from the chemical plants when I was a little girl. We didn’t know it was pollution. We thought it was a red waterfall, says Huang Qi, a 57yearold Shanghai resident. So the residential houses along the creek were unpopular, and only migrants with low ines would live in that area, she says. However, things have changed. The plants were closed and turned into riverside parks and the apartments in the new highrises, especial ly those facing the creek, are much sought after. East China University of Political Science and Law This is the famous former Saint John’s University, China’s firstever modern institution of higher education established by missionaries from the United States in 1879. The buildings bine Chinese and Western elements. Address: 1575 Wanhangdu Road, Changning district The old residential area After you leave the university from its east gate you will enter a shabby neighborhood that retains its original look. The alleys are narrow and the houses are overcrowded. Some things have not changed for many generations, such as raising chickens at home. Address: West Guangfu Road Moganshan Road This is an artsy street that has bee very popular among artists and fashionistas in recent years. Graffiti covers the walls on the winding street, where you can find a cluster of art galleries and creative industry offices. Sihang Warehouse Four banks jointly funded the construction of this warehouse, so it is named sihang, or four banks. The warehouse, built in 1931, was used for the storage of food, firstaid supplies and ammunition during the years of war. The building, which is also a masterpiece left by the Hungarian architect Laszlo Hudec in the 1930s, has been recently transformed into a center of creative industry workshops. Address: 1 Guangfu Road, Zhabei district 。 ⑤ 輸出分辨率 輸出分辨率是指激光打印機(jī)等輸出設(shè)備輸出的圖像每英寸的點(diǎn)數(shù)。 ④ 位分辨率 位分辨率也可稱為位深，用來(lái)衡量每個(gè)像素存儲(chǔ)的信息位數(shù)，這個(gè)分辨率決定在圖像的每個(gè)像素中存放多少顏色信息。如常見(jiàn)的 PC顯示器、掃描儀和數(shù)字相機(jī)等設(shè)備，各自都有一個(gè)固定得分辨率。 ② 設(shè)備分辨率 設(shè)備分辨率是指每單位輸出長(zhǎng)度所代表的點(diǎn)數(shù)和像素。另外，圖像的尺寸、分辨率和文件大小三者之間有很親密的關(guān)系，一個(gè)分辨率相同的圖像，如果尺寸不同，他的文件大小也不同，尺寸越大，文件越大。所以，在制作圖像時(shí)，不同品質(zhì)圖像需設(shè)定適當(dāng)分辨率才能最經(jīng)濟(jì)、有效地制作作品。 在數(shù)字化圖像中，分辨率的大小直接影響圖像的品質(zhì)。當(dāng)然，不同單位計(jì)算出來(lái)的分辨率各不相同，以厘米為單位比以英寸為單位計(jì)算的數(shù)值小得多。 例如， 72dpi表示該圖像每英寸含有 72個(gè)點(diǎn)或像素。 ？分別代表什么意義？ (10分 ) 答：分辨率可以分為以下幾種類型。 答：色彩的三個(gè)基
