字画鉴定评估工作者在处理书画真伪问题的过程中，不断总结经验，逐步形成了书画经验鉴定中的“眼学”。当然，“眼学”并非书画鉴定学，虽然有人力图将以“眼学”为主体的书画经验鉴定提升到学科层面。但是，从感性认识到理性认识，从经验积累到建立学科，还需要有更多的学术支撑和更完备的知识结构。

In the process of dealing with the authenticity of calligraphy and painting, the appraisers of calligraphy and painting have constantly summarized their experience and gradually formed the "ophthalmology" in the identification of calligraphy and painting experience. Of course, "ophthalmology" is not the identification of calligraphy and painting, although there are human resources to promote the professional identification of calligraphy and painting experience with "ophthalmology" as the main body to the subject level. However, from perceptual knowledge to rational knowledge, from experience accumulation to discipline establishment, more academic support and more complete knowledge structure are needed.

在艺术品科学鉴定的国际大趋势和注重文化与科技融合的国内新形势的共同影响下，在学习实践科学发展观活动的促进与指导下，书画鉴定由经验主导阶段走向科学发展阶段就具有了历史必然性。我们利用光学仪器对书画材质进行检测时发现，宣纸类书画纸具有指纹一样独特的纤维状态。于是就对这类书画纸的微观状态并结合墨色、印迹进行了大量的检测试验，证实了以下三点。

Under the joint influence of the international trend of scientific identification of artworks and the new domestic situation of focusing on the integration of culture and science and technology, and under the promotion and guidance of the activities of learning and practicing the scientific concept of development, the identification of calligraphy and painting has become historically inevitable from the experience-led stage to the scientific development stage. When we use optical instruments to detect the material of calligraphy and painting, we found that the rice paper type calligraphy and painting paper has a unique fiber state like fingerprints. Therefore, a large number of tests were carried out on the microscopic state of this kind of calligraphy and painting paper in combination with ink color and imprint, which confirmed the following three points.

1.每一张宣纸类书画纸的任何一处微观纤维状态都是不同的。人们能复制出同类的纸（即同地点、同年代、同原料、同批产、同方式的书画纸），但无法复制其纤维结构的微观状态。这种纤维结构状态的差异性，主要由其特殊的生产工艺所决定。

1. Each Xuan paper-like calligraphy and painting paper has a different microfiber state at any point. People can copy the same kind of paper (that is, the same place, the same age, the same raw material, the same batch of production, the same way of painting paper), but can not copy the microscopic state of its fiber structure. The difference of the fiber structure is mainly determined by its special production process.

切割工艺中的切割方式决定了纸浆纤维的长短不一，捞纸工艺中无序组合的纸浆纤维被竹帘捞出水面，各微小纤维都是以偶然状态凝聚形成纸张。于是，宣纸类书画纸在这种生产工艺中就必然形成了纤维结构状态的处处差异；

The cutting method in the cutting process determines the length of the pulp fiber. In the paper fishing process, the disorderly combined pulp fiber is fished out of the water by the bamboo curtain, and each tiny fiber is condensed into paper in an accidental state. Therefore, in this production process, there must be differences in the fiber structure of rice paper and calligraphy and painting paper;

2.墨、色、印迹融合在独特纤维结构上，其微观状态也必然独特。在微观视野中，每一幅使用了宣纸类书画纸原创作品都拥有了独特纸纤维结构和独特的墨、色、印迹状态。这两个独特的状态之结合，形成了该作品无法被复制的物质形。

2. The ink, color and imprint are integrated in the unique fiber structure, and its microscopic state is also unique. In the microscopic view, each original work using rice paper, calligraphy and painting paper has a unique paper fiber structure and unique ink, color and imprint state. The combination of these two unique states forms a material form that cannot be copied.

3.书画作品的物质形态是由纸、墨、色、印泥等材料结合成的物质结合体。这些材料往往因历史变异、品种差异而使其内部物质成分发生变化与差异。每一种不同物质成分的墨、色、印泥往往都具有不同时空的烙印，都能成为防伪、辨伪的依据。所以，用光学仪器对书画原作的物质成分进行定点检测并取证备案，也具有一定的防伪意义和作用。

3. The material form of calligraphy and painting works is a combination of paper, ink, color, ink and other materials. These materials often have changes and differences in their internal material composition due to historical variation and variety differences. Each kind of ink, color and ink paste with different material components often has different time-space imprints, which can become the basis for anti-counterfeiting and identification. Therefore, the use of optical instruments to detect the material composition of the original painting and calligraphy at a fixed point and obtain evidence for filing also has certain anti-counterfeiting significance and role.

书画纸历史悠久，在造纸工艺、原料成分、品种样式诸方面，因地域不同而存在区别，又随时代变迁而有所变化，有许多随时空变化而产生的特征和规律。利用现代科技手段检测不同年代、不同种类的书画纸，捕捉其规律性特征，是鉴定书画作品的一条科研途径。还有怎样的了解就来我们网站http://www.jinandayatang.com看看吧！

Calligraphy and painting paper has a long history. In terms of paper making technology, raw material composition, variety and style, there are differences due to different regions, and also changes with the changes of times. There are many characteristics and laws resulting from changes in time and space. It is a scientific research way to identify calligraphic and painting works by using modern scientific and technological means to detect different kinds of calligraphic and painting papers of different ages and to capture their regular characteristics.
