A. 古代發明了多少生活用品有多少是世界上最最早(ﾟДﾟ)ﾉ
1.由妲己發明的筷子。
2.牙刷
3.由嫘祖發明的梳子。
4.銅鏡。
5.皂角（長在樹上當做肥皂用的物品）
6.魯班發明的傘。
7.胭脂
等
B. 日本為什麼喜歡發明，生活用品方面的東西
因為日本人喜歡生活，喜歡在生活中鑽研，所以就發明生活用品方面的東西，生活中只要你真心，一定會有發明的。
C. 為什麼最近200年中國沒有發明一些人類用的東西，比如電子設備和日用品現在用的一切幾乎都是外國發明的
現在發展的電子科技，
比如手機，電腦，
都是人類用的啊，
至於外國的話，
那是因為我們中國現在還沒有外國這么牛逼轟轟，
畢竟我們科技在清朝的時候落後了一大段的
D. 求太空技術有關的日用品有哪些他們是如何被發明出來的
紙尿布，紙尿布本來是用在航天員身上的，後來才運用在嬰兒身上。
E. 中世紀的歐洲人發明了什麼生活用品
中世紀的歐洲人還發明了一些我們現代日常生活中十分熟悉的東西，包括專鍾和印刷書本屬。機械鍾發明於1300年前不久，此後迅速傳播開采。最早的鍾表太過昂貴，非私人所能購買，但城鎮很快競相在其重要公共建築上安裝精巧的鍾。這些鍾不僅顯示時間，而且顯示太陽、月亮、星辰的運行軌跡，還起著機械報時的作用。
F. 古人都發明創造了哪些生活用具
我國古代人的生活一直是現代人感興趣的話題。古人的生活條件雖然與現在相差很大，但專是屬事實上，古人發明創造的許多生活用具，大大彌補了物質條件的某些不足，使生活質量得到了不斷地提高。古人的生活用具很多，不可能一一加以敘述。在這之中的傘、筷子、冰箱、鍾表、扇子等，古今一直在用，體現了實用性強的特點。
G. 誰發明超市
The concept of a self-service grocery store was developed by Clarence Saunders and his Piggly Wiggly stores. A&P was the most successful of the early chains in Canada and the United States, having become common in North American cities in the 1920s. The general trend in retail since then has been to stack shelves at night and let the customers get their own goods and bring them to the front of the store to pay for them. Although there is a higher risk of shoplifting, the costs of appropriate security measures will be ideally outweighed by the economies of scale and reced labor costs.
According to the Smithsonian Institution, the first true supermarket in the United States was opened by ex-Kroger employee Michael J. Cullen, on August 4, 1930, in a 6,000 square foot (560 m²) former garage in Jamaica, Queens, New York.[1] The store, King Kullen, following King Kong, operated under the slogan "Pile it high. Sell it low." When Cullen died in 1936, there were seventeen stores in operation.
A Safeway advertisement from the 50'sExisting grocery chains like Kroger and Safeway at first resisted Cullen's idea, but eventually were forced to build their own supermarkets as the North American economy sank further into the Great Depression and consumers became price-sensitive to an degree never seen before.[2] Kroger took the idea one step farther and pioneered the first supermarket surrounded on all four sides by a parking lot.
Supermarkets proliferated in Canada and the United States, along with suburban areas after World War II. At present, North American supermarkets are often co-located with smaller retailers in strip malls and are generally regional rather than national. Kroger is probably the closest thing to a national chain in the United States but has preserved most of its regional brands like Ralphs, City Market and King Soopers. In Canada the largest food retailer is Loblaw Companies. Loblaw Companies operates grocery stores across Canada under a variety of regional names such as Fortinos, Zehrs and the largest Loblaws (named after the company itself). Sobeys is Canada's second largest supermarket with locations across the country, all under the same name. In the UK Tesco is the largest chain of supermarkets followed by ASDA and Sainsburys.
In Britain, France and other countries, the proliferation of out-of-town supermarkets has been blamed for the disappearance of smaller, local grocery stores and for increased dependency on the motor car (and the consequent traffic). In particular, some critics consider the practice of selling loss leaders to be anti-competitive, and are also wary of the negotiating power large retailers have with suppliers. Supermarkets are found around the world in dozens of countries.
It was formerly common for supermarkets to give trading stamps. Today, most supermarkets issue store-specific "members cards," "club cards," or "loyalty cards" which are scanned at the register when the customer goes to check-out. Typically, several items are given special discounts if the credit card-like devices are used.
Today supermarkets face price competition from discount retailers such as Wal-Mart and Zellers (non-union labor and greater buying power) and warehouse stores such as Costco (savings in bulk quantities).
H. 有什麼生活用品，是科學家從動物身上受到啟示，而發明的
烏賊和魚雷誘餌 烏賊體內的囊狀物能分泌黑色液體，遇到危險時它便釋放出這種黑色液體，誘騙攻擊者上當。潛艇設計者們仿效烏賊的這一功能讀者設計出了魚雷誘餌。魚雷誘醋似袖珍潛艇，可按潛艇的原航向航行，航速不變，也可模擬噪音、螺旋節拍、聲信號和多普勒音調變化等。正是它這種惟妙惟肖的表演，令敵潛艇或攻擊中的魚雷真假難辯，最終使潛艇得以逃脫。
蜘蛛和裝甲 生物學家發現蜘蛛絲的強度相當於同等體積的鋼絲的5倍。受此啟發，英國劍橋一所技術公司試製成猶如蜘蛛絲一樣的高強度纖維。用這種纖維做成的復合材料可以用來做防彈衣、防彈車、坦克裝甲車等結構材料。
長頸鹿和「抗荷服」 長頸鹿是目前世界上最高的動物，其大腦和心臟的距離約3米，完全是靠高達160~260毫米汞柱的血壓把血液送到大腦的。按一般分析，當長頸鹿低頭飲水時，大腦的位置低於心臟，大量的血液會湧入大腦，使血壓更加增高，那麼長頸鹿會在飲水時得腦充血或血管破烈等疾病而死。但是裹在長頸鹿身上的一層、厚皮緊緊箍住了血管，限制了血壓，飛機設計師和航空生物學家依照長頸鹿皮膚原理，設計出一種新穎的「抗荷服」，從而解決了超高速殲擊機駕駛員在突然加速爬升時因腦部缺血而引起的痛苦。這種「抗荷服」內有一裝置，當飛機加速時可壓縮空氣，也能對血管產生相應的壓力，這比長頸鹿的厚皮更高明了。
鯨魚和潛艇的「鯨背效應」 當代核潛艇能長時間潛航於冰海之下，但若在冰下發射導彈，則必須破冰上浮，這就碰到了力學上的難題。潛舴專家從鯨魚每隔10分鍾必須破冰呼吸一次中得到啟迪，在潛艇頂部突起的指揮台圍殼和上層建築方面，作了加強材料力度和外形仿鯨背處理，果然取得了破冰時的「鯨背效應」。
蝴蝶和衛星控溫系統 遨遊太空的人造衛星，當受到陽光強烈輻射時，衛星溫度會高達200攝氏度；而在陰影區域，衛星溫度會下降至零下200攝氏度左右，這很容易烤壞或凍壞衛星上的精密儀器儀表，它一度曾使航天科學家傷透了腦筋。後來，人們從蝴蝶身上受到啟迪。原來，蝴蝶身體表面生長著一層細小的鱗片，這些鱗片有調節體溫的作用。每當氣溫上升、陽光直射時，鱗片自動張開，以減少陽光的輻射角度，從而減少對陽光熱能的吸收；當外界氣溫下降時，鱗片自動閉合，緊貼體表，讓陽光直射鱗片，從而把體溫控制在正常范圍之內。科學家經過研究，為人造地球衛星設計了一種猶如蝴蝶鱗片般的控溫系統。
I. 日用品發明的由來
擼主指的是安全套？由來就是計劃生育啊，生多了養不起。
