The present study, from the cognitive perspective, takes into consideration the following three points: the cognition of apposition is based on the knowledge of types and categories of things and objects; the original expression and its appositional expression are used as two different expressions for the same thing or event seen from different perspectives; the essential relationship between the two is that, in spite of the identical feature in syntax, they refer to different aspects of the object described out of different considerations.

In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product"s quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block"s width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SENs immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.

对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

There are three things - OK, more than three thing - that I find people won't believe, even after you prove it to them: 1 Warming up your car on cold mornings is a waste of gas - just get in and drive, staying under 35 mph for a mile or two; 2 Gas is gas - buying high octane gas is a waste of money unless your car is one of the select few that specifically demands it; and 3 finding a tick on your dog does not signal the impending apocalypse.

Such doubts havesitimulated the researchers'curiosity and start to explore the students' terms This research proceeds by observation interview test using learning sheets and etc The purpose is to explore students' terms of scientific concepts sources of terms connections between students' usage nomenclature and chooses of usage The results of the research are as follows: 1 There are five kinds of naming principles for students' terms of scientific concepts: appearance habit function replacing and sound Appearance principle contains three categories: color shape and partial construction; habit principle contains custom and ability; replacing principle contains reality and non-reality 2 Students' terms of scientific concepts come from two ways: self-acquisition and learning through senses The former way is only a bit more common than the latter 3 There are three different relationships between students' usage of terms and nomenclature: one both the same in usage and meaning; the other both different; another different usage but the same meaning Normally terms that students used are various from nomenclature in the aspects of usage and meaning only a few would match and even rare for "Synonyms" to occur 4 Alternative options for students' scientific terms are maintenance adaptation or co-existence with formal scientific terms The most common way of selecting usage of terms is to maintain Sometimes students would adapt themselves once learn of scientist's term However some believe that very odd chances for both could exist at the same time

这样的疑问深深引起研究者的好奇，著手探索学生科学概念所使用的语言。本研究透过观察、访谈、学习单施测等方法来进行，目的在探讨学童在科学概念上所使用之学生惯用语、学生惯用语来源、学生惯用语与科学家用语之关联性、学生惯用语选择。研究结果如下：一、学童在科学概念上所使用之学生惯用语的命名原则有五种：外型、习性、功能、藉代称呼及声音，其中外型原则有颜色、体型及部份构造三类目，习性原则有习惯及能力两类目，藉代称呼原则有实体及虚拟两类目。二、学童在科学概念上所使用之学生惯用语有两种来源，分别为自己称取和听来。学生惯用语来源较多为自己称取，透过其他方式听来少一点，但两种来源的比率差距甚小。三、学童在科学概念上所使用之学生惯用语和科学家用语的关系有三种，分别为用语意涵均相同、用语不同意涵相同和用语意涵均不同。学生惯用语通常和科学家的用语是不同的，且其意涵也不同，只有部份学生惯用语和科学家用语意涵均相同，至於学生惯用语和科学家用语不同但意涵相同的极少。四、学童的科学概念相关学生惯用语选择有三种，分别为维持学生惯用语、改变成科学家用语和科学家与学生惯用语皆可。学童的科学概念相关学生惯用语选择，以维持学生惯用语最多，而有些时候学生会在得知科学家的用语后改变成科学家用语，但认为科学家用语和自己使用的学生惯用语皆可的则很少。
