Therefore, the size of the test piece of the bucket = chronograph can be set in the test device as long as it is The inside of the = can not be particularly limited, usually the length of 2 〇 ~ 5 〇 face, the width of 1 〇 ~ 2 〇 face bone 〇 ' ί * elastic means that the material is caused by stress, causing the molecules of the material, causing birefringence The phenomenon of the change in size, in the case of uniaxial stretching, since the body extension directions are uniform, the positive and negative of the complex photoelastic coefficient exhibited when the test piece is extended is measured. Therefore, as for the extension of the above-mentioned measurement interesting film, it is only necessary to set the recording orientation to a stable magnification. For example, the soft substance of the adhesive is likely to be relieved by the alignment or the stress is relieved, and if the elongation is small, the measurement may not be performed stably. The orientation of the spindle can be extended by about 2 to 5 times of the length. If it is a hard substance such as a film, the length of the original test piece can be extended by about i 01 to 2 times.

The ethylenically unsaturated compound (C), and the amount of i曰&amp;, relative to the acrylic resin (Α_ parts by weight is 00 parts by weight) and the aromatic compound (8) is relative to the aromatic compound (8) and Dilute 47 201134905 Total of unsaturated unsaturated bismuth compounds (C); the content of f is related to (_1%) greater than 5Gm 〇 1%. 11. - 雠 接 接 ' is characterized by: propylene glycol resin (A) a polymer comprising (a monomeric group of an ethylenically unsaturated group), an aromatic compound (B) having one ethylenically unsaturated group, and an organic solvent. 12. - a splicing and a composition, It is characterized in that it contains an acrylic acid (4), an aromatic compound (8) containing one ethylenic acid &lt;saturated group, and an ethylenic acid compound (c)* containing two or more ethylenic groups. , the photoelastic coefficient of the acrylic resin (4) is 贞' and the hardening of the aromatic compound (B) and the ethylenically unsaturated compound (C) The photoelastic coefficient of the object is positive.
