字畫鑒定評估工作者在處理書畫真偽問題的過程中，不斷總結經驗，逐步形成了書畫經驗鑒定中的“眼學”。當然，“眼學”并非書畫鑒定學，雖然有人力圖將以“眼學”為主體的書畫經驗鑒定提升到學科層面。但是，從感性認識到理性認識，從經驗積累到建立學科，還需要有更多的學術支撐和更完備的知識結構。

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.

在藝術品科學鑒定的國際大趨勢和注重文化與科技融合的國內新形勢的共同影響下，在學習實踐科學發展觀活動的促進與指導下，書畫鑒定由經驗主導階段走向科學發展階段就具有了歷史必然性。我們利用光學儀器對書畫材質進行檢測時發現，宣紙類書畫紙具有指紋一樣獨特的纖維狀態。于是就對這類書畫紙的微觀狀態并結合墨色、印跡進行了大量的檢測試驗，證實了以下三點。

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.每一張宣紙類書畫紙的任何一處微觀纖維狀態都是不同的。人們能復制出同類的紙（即同地點、同年代、同原料、同批產、同方式的書畫紙），但無法復制其纖維結構的微觀狀態。這種纖維結構狀態的差異性，主要由其特殊的生產工藝所決定。

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.

切割工藝中的切割方式決定了紙漿纖維的長短不一，撈紙工藝中無序組合的紙漿纖維被竹簾撈出水面，各微小纖維都是以偶然狀態凝聚形成紙張。于是，宣紙類書畫紙在這種生產工藝中就必然形成了纖維結構狀態的處處差異；

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、印跡融合在獨特纖維結構上，其微觀狀態也必然獨特。在微觀視野中，每一幅使用了宣紙類書畫紙原創作品都擁有了獨特紙纖維結構和獨特的墨、色、印跡狀態。這兩個獨特的狀態之結合，形成了該作品無法被復制的物質形。

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.書畫作品的物質形態是由紙、墨、色、印泥等材料結合成的物質結合體。這些材料往往因歷史變異、品種差異而使其內部物質成分發生變化與差異。每一種不同物質成分的墨、色、印泥往往都具有不同時空的烙印，都能成為防偽、辨偽的依據。所以，用光學儀器對書畫原作的物質成分進行定點檢測并取證備案，也具有一定的防偽意義和作用。

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.

書畫紙歷史悠久，在造紙工藝、原料成分、品種樣式諸方面，因地域不同而存在區別，又隨時代變遷而有所變化，有許多隨時空變化而產生的特征和規律。利用現代科技手段檢測不同年代、不同種類的書畫紙，捕捉其規律性特征，是鑒定書畫作品的一條科研途徑。還有怎樣的了解就來我們網站http://www.longxiapy22.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.
