第二篇:交大 運營管理 第一次作業
工藝專業化和對象專業化各有什么優缺點?他們各自適合哪種情況? 答:
1、工藝專業化的優缺點:
工藝專業化的優點是:對產品品種變化有較強的適應能力。工藝專業化的缺點是: 1)生產率較低;
2)生產過程的連續性較差,運輸距離長。
3)計劃管理、生產調度、質量管理、在 制品管理等管理工作變得
復雜,使管理工作量大為增加。
2、對象專業化的優缺點:
對象專業化的優點是:
1)生產的專業化程度高,從而可以獲得 較高的勞動生產率;因此,生產周期長,在制品量大,因而相應的費用支出就高。
2)管理工作較簡單。
對象專業化的缺點:適應性差,設備利用率不高,不利于工人交流.與工藝專業化正好相反。

四、主觀題(共17道小題)
52.今有軟化點分別為95℃和25℃的兩種石油瀝青。某工程的屋面防水要求使用軟化點為75℃的石油瀝青,問應如何配制?
解:
軟化點為 95℃ 的石油瀝青用量 =(95℃-75℃)/(95 ℃- 25℃)× 100 % = 28.6 %
軟化點為 25℃ 的石油瀝青用量 =100 %- 28.6 %= 71.4 %
所以,軟化點為 95℃ 的石油瀝青用量為 28.6 %;軟化點為 25℃ 的石油瀝青用量為 71.4 %。
53.已知某混凝土的試驗室配合比為 C∶S ∶G = 1∶1.92 ∶3.97,W/C= 0.56, 配制1m3 混凝土水泥用量為300Kg。施工現場砂、石的含水率分別為5% 和1%,求施工配合比。
參考答案:解:按試驗室配合比,1m3混凝土中各種材料得用量為:
C= 300Kg ; W = 300 × 0.56 = 168Kg ; S = 300 × 1.92 = 576Kg ; G = 300 × 3.97 = 1191Kg ;
所以,施工配合比為:
C= 300Kg ; W = 168-576 × 5 %-1191 × 1 %= 127Kg ;
S = 576 ×(1 + 5 %)= 605Kg ; G = 1191 ×(1+1 %)= 1203Kg ;
施工配合比為: C= 300Kg ; W = 127Kg ; S = 605Kg ; G = 1203Kg。
54.假設混凝土抗壓強度隨齡期的對數而直線增長,已知1d強度不等于0,7d抗壓強度為21MPa,14d抗壓強度為26.0MPa,求28d強度為多少?
解:
設混凝土n天的抗壓強度為fn,齡期為n,則 fn=Algn + B ①
又有: f7 = Alg7 + B ②
f14 = Alg14+ B ③
由式 ②③得 : A=16.61 ; B = 6.96,代入式 ①得: f28 = 16.61lg28+ 6.96 = 31MPa
55.填充材料對瀝青有何影響?
答:瀝青與堿性礦粉之間具有較強的吸附力,在礦粉表面形成一層結合牢固的瀝青膜,即所謂“結構瀝青”。“結構瀝青”具有較高的粘性、大氣穩定性,較小的溫度感應性。提高了瀝青膠的粘結性、耐熱性、大氣穩定性
56.為何石灰屬于氣硬性膠凝材料?
答:石灰的凝結硬化是兩個同時進行的過程:干燥結晶,碳化反應;
以上過程只能在空氣中進行。
石灰硬化后的主要產物是Ca(OH)2,而Ca(OH)2溶于水,不能在潮濕和水中保持其強度。
57.簡述混凝土強度的影響因素。
答:①由f28=Afc(C/W-B)
混凝土強度主要取決于水泥等級(水泥強度)和水灰比,水泥等級提高,水灰比降低則混凝土強度提高。
②骨料品種,碎石混凝土強度高于卵石混凝土(配比相同)。
③攪拌和搗實方法。
④養護條件,齡期。⑤試驗條件、試件尺寸。
58.為什么說材料表觀密度是一項重要基本性質。
答: 答:由表觀密度可以說明材料其他一些性質,同類材料的表觀密度大說明其孔隙小,吸水率一般也小,強度、抗凍性、抗滲性好,導熱系數高。
59.名詞解釋:堆積密度
答:
堆積密度是指粉狀或粒狀材料在堆積狀態下,單位體積的質量。
60.名詞解釋:抗滲性
答:抗滲性是指材料抵抗壓力水滲透的能力。
61.名詞解釋:混凝土的強度等級
答:混凝土的強度等級是指按混凝土立方體抗壓強度來劃分的強度等級。
62.名詞解釋:石灰陳伏
答:石灰陳伏是指石灰在化灰池中放置兩周以上再使用的過程。
63.名詞解釋:混凝土拌和物的粘聚性
答:混凝土拌和物的粘聚性是指混凝土拌和物在施工過程中其組成材料之間有一定的粘聚力,不致產生分層和離析的現象。
64.名詞解釋:砂漿的流動性
答:砂漿的流動性是指砂漿在自重或外力的作用下產生流動的性質。
65.名詞解釋:石油瀝青的針入度
答:石油瀝青的針入度是指在規定溫度25 ℃條件下,以規定重量100g 的標準針,經歷規定時間5s 貫入試樣中的深度。
66.混凝土拌合物離析
答:混凝土拌合物離析是指混凝土拌和物由于密度和粒徑不同,在外力作用下組成材料的分離析出的現象。
67.名詞解釋:氣硬性膠凝材料
答:氣硬性膠凝材料是指只能在空氣中硬化,保持并繼續發展其強度的膠凝材料。
68.名詞解釋:時效敏感性
答:時效敏感性是指因時效而導致鋼材性能改變的程度的大小。

Directions: For this part, you are allowed 30 minutes to write a composition on the topic “Online Shopping”.You should write no less than 80 words.Just as its name implies, online shopping is to conduct the shopping activities online.With the development of Internet and electronic commerce,it seems to be gaining in popularity.Online shopping is accessible round the clock and it makes the world's marketplace at your fingertips.It is so convenience that you can buy whatever you want even at 3 a.m.in the morning;you can choose from a wider variety of things available for you to shop which may not be available in the local brick and mortar stores.What's more,it's always cheaper for you.However,given the lack of ability to inspect merchandise before purchase, consumers are at higher risk of fraud on the part of the merchant than in a physical store.So,when shopping online,we have to choose goods with care.But all in all, I would say its advantages outweigh its disadvantages.
