书写时序的判断在笔迹检验鉴定中,常作为确认单字笔迹的笔顺特征,判定文件中是否存在添改写事实,是否存在伪装等变造事实的依据而被广泛使用。笔迹书写时序的无损判定常常借助于笔迹所反映出的内在实质,即习惯性书写动作系统。针对书写速度较慢的无连笔、无交叉字迹笔画中书写时序的判定,主要是通过相邻笔画起收笔反射动作的照应关系,单字中关键性笔画的运笔趋势和相同的相邻笔画的间距等方面进行判断。针对书写速度较快的有连笔字迹笔画书写时序的判定则主要是透过把握书写动作中“形连”与“意连”的关系来进行。在字迹中有交叉笔画的书写时序的判断中,对使用水溶性色料的笔种,常通过墨水的洇散现象、纸张纤维的流向、墨水拖带现象等特征进行分析;对使用油溶性色料的笔种,常通过笔画沟痕特征、色料堆积特征、笔痕光泽特征等微观现象进行判断。 The judgment of writing sequence is often used as a stroke-sequence feature to confirm single-word handwriting. It is widely used to determine whether there exists any fact that exists in the document, such as modification and rewriting, and whether there are any altered facts such as camouflage. Nondestructive judgments of handwriting writing timing often rely on the intrinsic substance reflected in handwriting, the habitual writing motion system. Judgment of the writing sequence in the strokes-free and non-cross-strokes of strokes, which is slow in writing, is mainly based on the correspondence relationship between the reflex actions of the adjacent strokes and the key strokes in the single word and the same adjacent strokes Pitch and other aspects of judgment. For the writing speed is faster, the writing sequence of writing stroke with stroke pen is mainly determined by grasping the relationship between writing style and writing style. In writing, there are cross-stroke writing timing judgments, the use of water-soluble pigment pen species, often through the phenomenon of tangled ink, paper fiber flow, ink drag phenomenon and other characteristics were analyzed; the use of oil-soluble color Of the pen species, often through the strokes groove strokes traits, pigment accumulation features, pen marks, gloss characteristics of micro-phenomena to judge.
