查询词典 abstracting

On the basis of these observation, the author scans again some problems in the classical curricula from the point of view of teaching to indicate that the scientificalness of teaching is not only limited to the demand of knowledge scientificalness. It also requires that the teachers should make individual treatment in order to subliming and abstracting the content of teaching to make it more thoughtful. In this way it can be easily digested and absorbed by the students.

In the cost approach, the value of a property is derived by estimating the replacement or reproduction cost of property and then abstracting the amount of depreciation (i.e., deterioration and obsolescence) in the property from all causes.

成本途径中，资产的价值的确定是通过估算资产的复原重置成本或更新重置成本，进而扣除该资产由于各种原因所形成的折旧额。

But during the process of democratic voting, providing public goods are usually one of the main measures of abstracting the supporting of electorates. In the scope of a country, a government needs to provide so many public goods, which related to so many profits. So it is very little that a process of providing some public good can determine the process of voting.

但是，由于在民主的竞选过程中，对公共物品的提供往往是参选各方获得选民支持最主要的手段之一，在一个国家的范围之内，一个政府所需要提供的公共物品往往是多方面的，并且涉及的利益也是多方面的，因此，某个特定公共物品的提供左右选举过程的现象往往比较少见。

由于票据背景的复杂性、油墨的不均匀性、位置的不确定性以及采集带来的噪声等因素，使得印章的提取与修复面临较大困难。

Borrowing from Herbert Simon and also influenced by the ideas of existential phenomenologists such as Maurice Merleau-Ponty and Martin Heidegger, McClamrock suggests that man's condition of being-in-the-world ("Dasein","In-der-welt-sein") makes it impossible for him to understand himself by abstracting away from it and examining it as if it were a detached experimental object of which he himself is not an integral part.

借鉴Herbert Simon，受到存在主义现象学家梅洛-庞蒂（Maurice Merleau-Ponty）和海德格尔的影响，McClamrock提出了这样的看法：人的状况是&在世界之中存在&（&Dasein&，&In-der-welt-sein&），但人们却想采用了从这种状况中抽离出来并检验它的方法来理解他自己，就好像这种状态是一个被分开的经验性对象，对它来说他不是一个整合而不可分的部分，这是不可能成功的。
