A. 古代发明了多少生活用品有多少是世界上最最早(゚Д゚)ノ
1.由妲己发明的筷子。
2.牙刷
3.由嫘祖发明的梳子。
4.铜镜。
5.皂角(长在树上当做肥皂用的物品)
6.鲁班发明的伞。
7.胭脂
等
B. 日本为什么喜欢发明,生活用品方面的东西
因为日本人喜欢生活,喜欢在生活中钻研,所以就发明生活用品方面的东西,生活中只要你真心,一定会有发明的。
C. 为什么最近200年中国没有发明一些人类用的东西,比如电子设备和日用品现在用的一切几乎都是外国发明的
现在发展的电子科技,
比如手机,电脑,
都是人类用的啊,
至于外国的话,
那是因为我们中国现在还没有外国这么牛逼轰轰,
毕竟我们科技在清朝的时候落后了一大段的
D. 求太空技术有关的日用品有哪些他们是如何被发明出来的
纸尿布,纸尿布本来是用在航天员身上的,后来才运用在婴儿身上。
E. 中世纪的欧洲人发明了什么生活用品
中世纪的欧洲人还发明了一些我们现代日常生活中十分熟悉的东西,包括专钟和印刷书本属。机械钟发明于1300年前不久,此后迅速传播开采。最早的钟表太过昂贵,非私人所能购买,但城镇很快竞相在其重要公共建筑上安装精巧的钟。这些钟不仅显示时间,而且显示太阳、月亮、星辰的运行轨迹,还起着机械报时的作用。
F. 古人都发明创造了哪些生活用具
我国古代人的生活一直是现代人感兴趣的话题。古人的生活条件虽然与现在相差很大,但专是属事实上,古人发明创造的许多生活用具,大大弥补了物质条件的某些不足,使生活质量得到了不断地提高。古人的生活用具很多,不可能一一加以叙述。在这之中的伞、筷子、冰箱、钟表、扇子等,古今一直在用,体现了实用性强的特点。
G. 谁发明超市
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. 有什么生活用品,是科学家从动物身上受到启示,而发明的
乌贼和鱼雷诱饵 乌贼体内的囊状物能分泌黑色液体,遇到危险时它便释放出这种黑色液体,诱骗攻击者上当。潜艇设计者们仿效乌贼的这一功能读者设计出了鱼雷诱饵。鱼雷诱醋似袖珍潜艇,可按潜艇的原航向航行,航速不变,也可模拟噪音、螺旋节拍、声信号和多普勒音调变化等。正是它这种惟妙惟肖的表演,令敌潜艇或攻击中的鱼雷真假难辩,最终使潜艇得以逃脱。
蜘蛛和装甲 生物学家发现蜘蛛丝的强度相当于同等体积的钢丝的5倍。受此启发,英国剑桥一所技术公司试制成犹如蜘蛛丝一样的高强度纤维。用这种纤维做成的复合材料可以用来做防弹衣、防弹车、坦克装甲车等结构材料。
长颈鹿和“抗荷服” 长颈鹿是目前世界上最高的动物,其大脑和心脏的距离约3米,完全是靠高达160~260毫米汞柱的血压把血液送到大脑的。按一般分析,当长颈鹿低头饮水时,大脑的位置低于心脏,大量的血液会涌入大脑,使血压更加增高,那么长颈鹿会在饮水时得脑充血或血管破烈等疾病而死。但是裹在长颈鹿身上的一层、厚皮紧紧箍住了血管,限制了血压,飞机设计师和航空生物学家依照长颈鹿皮肤原理,设计出一种新颖的“抗荷服”,从而解决了超高速歼击机驾驶员在突然加速爬升时因脑部缺血而引起的痛苦。这种“抗荷服”内有一装置,当飞机加速时可压缩空气,也能对血管产生相应的压力,这比长颈鹿的厚皮更高明了。
鲸鱼和潜艇的“鲸背效应” 当代核潜艇能长时间潜航于冰海之下,但若在冰下发射导弹,则必须破冰上浮,这就碰到了力学上的难题。潜舴专家从鲸鱼每隔10分钟必须破冰呼吸一次中得到启迪,在潜艇顶部突起的指挥台围壳和上层建筑方面,作了加强材料力度和外形仿鲸背处理,果然取得了破冰时的“鲸背效应”。
蝴蝶和卫星控温系统 遨游太空的人造卫星,当受到阳光强烈辐射时,卫星温度会高达200摄氏度;而在阴影区域,卫星温度会下降至零下200摄氏度左右,这很容易烤坏或冻坏卫星上的精密仪器仪表,它一度曾使航天科学家伤透了脑筋。后来,人们从蝴蝶身上受到启迪。原来,蝴蝶身体表面生长着一层细小的鳞片,这些鳞片有调节体温的作用。每当气温上升、阳光直射时,鳞片自动张开,以减少阳光的辐射角度,从而减少对阳光热能的吸收;当外界气温下降时,鳞片自动闭合,紧贴体表,让阳光直射鳞片,从而把体温控制在正常范围之内。科学家经过研究,为人造地球卫星设计了一种犹如蝴蝶鳞片般的控温系统。
