交换

It is unrealiable because the only authoritative ground for this figure——a figure that would turn life into a determinate figure for consciousness would be the system of consciousness itself , ie, the system of knowing, here taken as a closed tropological system ie, a system of substitutions and exchanges based on a knowledge of entities and their exchangeable properties.

这是因为这个比喻唯一有权威的根据——这个比喻将会把生命变成对意识的规定的比喻——将会是意识体系本身，即认识活动的体系，在这里被认为是一个封闭的转喻体系（即，建立在对诸实体entities与其可交换的性质的认识之基础上的一个诸替代和交换的体系。

As a key equipment of NGN, the trunking media gateway provides the conversion between PSTN and packet network.

作为NGN的核心设备，媒体网关提供了PSTN电路交换和分组网包交换的转换。

The factors of temperature and humidity influenced on film thickness and order of layer were studied, in which pulling speed and pulling times were also included. It showed that the thickness of single dip-coating film reached 0.23 μm ~ 0.625 μm, and the degree of order of surface layer were still holding much higher.b Adopting calcined or uncalcined mesoporous silica membrane as matrix, nano zirconia particles were assembled through ion exchange method and ion-template exchange method.

结果表明，单次提拉膜膜厚0.23μm～0.625μm、8次提拉后表层膜仍有一定的有序性； b以自制的介孔氧化硅煅烧/未煅烧厚膜样为基体，采用离子交换法/离子模板交换法组装锆氧纳米粒子，选用DSC-TG、FT-IR、Uv-vis、SAXRD等对不同组装方法、锆源浓度、pH值等组装条件下ZrO_2/介孔氧化硅厚膜组装效果进行评价。

In this article, three representative oil and fat resourse (edible raw oil, unedible linseed oil and waste oil and fat) were used to study the fatty acid methyl ester preparation technology, and the products from different technologies were compared and analysed. For plant oil, ester exchange process was performed immediately after simple decolorating and alkali refining pretreatment.

对于植物油脂，采用简单的脱色、碱炼预处理后，直接进行酯交换的工艺；对于废油脂，由于其成分变质较严重，预处理也显得相对复杂，采用了先预酯化再酯交换的工艺和先皂化酸化后再酯化的两种工艺。

Not only that, along with the commodity economic high development, in under the law of value control, for realizes the goal of exchange, it possibility cause the producer partly even entire to give up the independent spirit of creation.

不仅如此，随着商品经济的高速发展，在价值规律的支配下，为实现其交换目的，这种交换目的有可能使生产者部分甚至整个地放弃民间创作的自主精神。

The production process of fatty acid methyl ester with high acid value acidulated oil and fatty acid replaced superior quality fat and oil by high temperature gas phase method and supplemental ester translation process was also introduced.

对间歇式酯化-酯交换工艺进行了具体分析，并着重介绍了采用高温气相法及补充酯交换工艺，以高酸值酸化油和脂肪酸代替高档油脂生产脂肪酸甲酯的生产工艺。
