据说,饺子原名“娇耳”,是东汉“医圣”张仲景发明的,已经有一千八百多年的历史。当时饺子是药用,张仲景用面皮包一些可以祛寒的药材用来治病,避免病人耳朵生冻疮。之后,饺子在漫长的发展过程中有了“煮角”“焦耳”“扁食”“匾食”“饺饵”“粉角”“牢丸”等名称。 相似文献

在美国,烧烤是一种文化 总被引:1,自引:0,他引:1
BBQ!看到这三个字母,不要以为你out得不知道又出了什么新的高科技数码产品或玩法了。不是不是。它不过是中外老饕们对Barbecue——"烧烤"一词的缩写。过年了,请老外包饺子、吃饺子,不管在国内,还是世界各地的唐人街,甚或我们的驻外机构,大概都是一项少不了的节目。 相似文献

正速冻食品主要分为未经加工直接进行速冻处理和经过制作加工之后再进行速冻处理两类,那么,食用经过如此处理的食品是否安全、健康?随着经济的发展与生活水平的提高,人们对食品种类的需求逐日增加,除了购买价格不菲的跨地域新鲜食物,价格合理的速冻食品也是消费者不错的选择。当下超市中销售的速冻食品主要分为两类。一类是经过制作加工之后再进行速冻处理的食品,例如各种品牌的速冻饺子、鱼丸、披萨等;另一类是未经加工直接进行速冻处理的食品,例如速冻海鲜、蔬菜、水果等。那么,经过如此速冻处理的食品是否安全、健康呢? 相似文献

Japan started the national project “COURSE 50” for CO2 reduction in the 2000s. This project aimed to establish novel technologies to reduce CO2 emissions with partially utilization of hydrogen in blast furnace-based ironmaking by 30% by around 2030 and use it for practical applications by 2050. The idea is that instead of coke, hydrogen is used as the reducing agent, leading to lower fossil fuel consumption in the process. It has been reported that the reduction behavior of hematite, magnetite, calcium ferrite, and slag in the sinter is different, and it is also considerably influenced by the sinter morphology. This study aimed to investigate the reduction behavior of sinters in hydrogen enriched blast furnace with different mineral morphologies in CO–CO2–H2 mixed gas. As an experimental sample, two sinter samples with significantly different hematite and magnetite ratios were prepared to compare their reduction behaviors. The reduction of wustite to iron was carried out at 1000, 900, and 800°C in a CO–CO2–H2 atmosphere for the mineral morphology-controlled sinter, and the following findings were obtained. The reduction rate of smaller amount of FeO led to faster increase of the reduction rate curve at the initial stage of reduction. Macro-observations of reduced samples showed that the reaction proceeded from the outer periphery of the sample toward the inside, and a reaction interface was observed where reduced iron and wustite coexisted. Micro-observations revealed three layers, namely, wustite single phase in the center zone of the sample, iron single phase in the outer periphery zone of the sample, and iron oxide-derived wustite FeO and iron, or calcium ferrite-derived wustite 'FeO' and iron in the reaction interface zone. A two-interface unreacted core model was successfully applied for the kinetic analysis of the reduction reaction, and obtained temperature dependent expressions of the chemical reaction coefficients from each mineral phases. 相似文献
