Description
Technical field
This utility model relates to a kind of fuming box, particularly relates to a kind of portable comprehensive fuming box, belongs to electric equipment neck
Territory.
Background technology
Fingerprint is streakline protruding on epidermis, and fingerprint is jointly acted on by h and E factor and formed, everyone finger
Stricture of vagina has the characteristics such as uniqueness, the most constant and tactile thing trace, therefore, often by first of the evidence of judicial circuit.Fingerprint
The fingerprint formed after contact object includes three kinds, and the first be obvious stricture of vagina, i.e. visually seen from lines, as hands be stained with paint, blood,
The article transfers such as ink form.The second is molding stricture of vagina, and fingerprint is by soft substance, if hands contact printing is on wax candle, clay
The fingerprint stayed；The third is latent fingerprint, and this kind of fingerprint is the fingerprint formed through transfers such as health nature secretions such as perspiration
Lines, is visually difficult to find, is modal fingerprint in spot.
In fingerprint technique, the problem of most critical is the appearing technique of latent fingerprint, and Appearing Techniques of Human Fingerprints is developed so far to be gone up
