To the resistance values of emerald jewellery studies have shown that the resistance value of natural jadeite ornaments between 10M Ω to 20G Ω.
According to the test result of the natural jadeite ornaments of 300 various colorss, various granularities, various transparencies, about 67% natural bird with red feathers
The resistance value of emerald green ornaments is between 10M Ω -880M Ω；The resistance value of about 25% natural jadeite ornaments 900M Ω -5G Ω it
Between；The resistance value of about 8% natural jadeite ornaments is between 5G Ω -20G Ω；The resistance value of about 7% natural jadeite ornaments exists
Greater than 20G Ω.The resistance measurement of 86 treated jadeite (B goods, B+C goods) ornaments is the result is that the resistance value of whole samples is greater than
20GΩ.The big reason of treated jadeite resistance value is that the hole inside emerald is filled by resin glue, and insulating properties improves.And natural bird with red feathers
There are various impurity in varying numbers, such as iron oxide, hydrous ferric oxide, moisture for emerald green internal void, when in natural jadeite
When portion's hole is more, the reduction of its resistance value is typically resulted in, whereas if to lack resistance value big for the internal capillary hole of natural jadeite.According to
It is similar with the resistance value of treated jadeite (B goods, B+C goods) less than the resistance value of 10% natural jadeite according to existing result of study, but
It is that can be identified by other identification technologies.Experimental study shows that natural jadeite of the resistance value greater than 20G Ω does not have
Ultraluminescence, and treated jadeite (the B goods, B+C goods) overwhelming majority of the resistance value greater than 20G Ω has moderate strength or more
The Ultraluminescence that naked eyes easily identify.And the resistance value with Ultraluminescence natural jadeite is below 5G Ω.So if can incite somebody to action

Ω grades (Vr3)
When acquisition sample resistance value be greater than 20G Ω, trigger first first comparator 5-21；When the sample of acquisition
When resistance value is less than 20G Ω greater than 1G Ω, second first comparator 5-22 is triggered；When the resistance value of the sample of acquisition is less than 1G
When Ω is greater than 10M Ω, third first comparator 5-23 is triggered.
First indicator light 6-11 is red, and the second indicator light 6-12 is yellow, and third indicator light 6-13 is green, first
A first comparator 5-21 corresponding first indicator light 6-11, the corresponding second indicator light 6-12 of second first comparator 5-22, the
Three first comparator 5-23 correspond to third indicator light 6-13.First indicator light 6-11 indicates doubtful treated jadeite, by than first
A first comparator 5-21 triggering；Second indicator light 6-12 indicates natural jadeite, but the pollution of vigilant sample surfaces is needed to make
Decline at resistance value, wipe samples is needed to measure again, is triggered by second first comparator 5-22；Third indicator light 6-13 shows
Natural jadeite is triggered by third first comparator 5-23.In this manner it is possible to true according to lamp bright in several indicator light 6-1
Determine the type of emerald.
Meanwhile when the returned signal acquisition resistance 5-1 electric signal (Vc) obtained is greater than the overcurrent reference voltage of setting
(Vr4), then the second comparator 7-2 is triggered, by relay 7-1 power cutoff, only reset switch 9 can be just once again powered up.It is high
Pressure generator 3 is connect by resistance 7-3 with resistance measurement mechanism 4, and resistance is 10 Ω, so that maximum high-tension current is less than
120 μ A, human contact test probe oncontacting inductance.
Application method two
First comparator 5-2 in application method one is replaced with into microprocessor (also known as single-chip microcontroller, model
STC15W408AS), meanwhile, display screen 12 is set at indicator light 6-1, display screen 12 is connect with microprocessor.
By the first via converter of microprocessor, input analog electrical signal (Vc) is converted into accordingly by program
Resistance value numerical value, identified using setting program, when acquisition sample resistance value be greater than 20G Ω, to the first indicator light
6-11 power supply, the first indicator light 6-11 indicate that doubtful treated jadeite is lighted and flashed, and show on the display 12 corresponding
Text prompt: doubtful processing.When acquisition sample resistance value between 20-1G Ω, the second indicator light 6-12 is lighted and is dodged
Bright, indicate natural jadeite, and show corresponding text prompt on the display 12: wipe samples measure again.When acquisition
The resistance value of sample is less than between 1G Ω -10M Ω, and third indicator light 6-13 is lighted and flashed, and issued with buzzer 14
Sound indicates natural jadeite, and shows corresponding text prompt: natural jadeite on the display 12.
Microprocessor was provided with flow control, using the electric signal of the first via converter analysis input of microprocessor
(Vc), electric signal (Vc) is converted by program by corresponding current values, once electric current is greater than the threshold value of setting, power cutoff
2, only reset switch 9 can be just once again powered up.Microprocessor is provided with battery capacity deficiency and indicates warning circuit, using micro process
Device the second road converter acquires the component voltage of battery, and the component voltage of battery is analyzed by program, when electric quantity consumption to possible shadow
When ringing test result, the component voltage of battery is less than the threshold value of setting, issues the instruction of not enough power supply, purple indicating light 11 is lighted simultaneously
Flashing, and show on the display 12: battery capacity is insufficient.Microprocessor is provided with timing and closes power supply control, using micro- place
The timer of reason, by program judge instrument open after in 3 minutes without test action, then close power supply 2.
It should be noted last that the above specific embodiment is only used to illustrate the technical scheme of the present invention and not to limit it,
Although being described the invention in detail referring to example, those skilled in the art should understand that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit and scope of the technical solution of the present invention, should all cover
In the scope of the claims of the present invention.
