New pit jadeite and old pit jadeite difference The new pit jadeite and the old pit jadeite's main difference looks at the jadeite pulp whether exquisite close. The new pit jadeite's raw material short texture, some quality of material winter melon pulp or the rice polishings radish, the bottom color by creamy white, grayish white, the light green majority, the ore looked like is probably likely likely the thick salt particle presses in one.

The old pit jadeite flood peak is bad, the structure is very close. Cotton and kapok difference: The old pit jadeite cotton and kapok are very few, has,cheap evening dresses the cotton and kapok also presents slight punctual, the new pit jadeite cotton and kapok are many, and occasionally will have some to ice the dregs same impurity likely. Colloid:

The old pit jadeite will sometimes give the human in the vision one kind of insightful feeling, the careful observation will also think that in the pulp will be as if containing the colloid, the colloid uniform distribution, will dissolve in which.

The new pit jadeite will not have. Gradation contrast: The flood peak good old pit jadeite general meeting has a gray. If does not have the gray and the flood peak good, the kind of old pit jadeite, certainly is priceless. Fluorescence: The flood peak good old pit jadeite will sometimes feel that will be dispersing the fluorescence from the jadeite interior. The new pit jadeite very little has the fluorescence phenomenon.

The beautiful jade · appreciates Song agate floral formula bowl The agate is one of our country tradition jades, the color is rich,discount costume jewellery assumes the translucent glassy luster, was known as “thousand kind of agate ten thousand kind of jade” saying. Agate multi-jade colors, therefore is called the red jade.

Its solidity ratio Hetian jade is also high, and further because its nature is crisp, toughness is bad, from this increased the manufacture to be possible to supply to set at the use utensil's processing technology difficulty abundantly. The agate is vulnerable, therefore is handed down for generations the agate product is extremely precious.

This agate floral formula bowl which has in the Hebei Province museum is the Song Dynasty product, has saved the world millennium. Its quality of material is compact, glittering and translucent carving, deep abdomen, encircles the foot, the shape,South Sea Pearls if is in full bloom flower of the Chinese flowering crabapple, elegant beautiful, unique refined. Six petals gentle charming “flower petal” on, obviously the purple-red streak, the actual situation mutual promotion of the five elements, complements each other, has unfolded the agate color fully variegated, the glittering and translucent carving characteristic, entire carves carves the nature to be smooth.

As the Chinese · awn city (Pan-Asian) a jewelry handicraft exposition activity's part, on December 27 the morning, the awn city first session jewelry expert forum converged numerous domestic and foreign well-known experts and professors, suggests plans together for the Yunnan jewelry industry's development. “our jewelry industry is facing the excellent opportunity.”Awn municipal party committee Secretary Cai four great said.

Presently, wholesale fashion jewellery three big policies boost Yunnan to develop. First, western big development; second, bridgehead construction; third, “a nucleus two wing” development measure. This had decided the jewelry industry's development is hopeful, has the vigor.

Expert sound Morocco too: Will not transform the idea to will certainly to eliminate “Yunnan's jewelry profession must develop, the idea must transform, must the renewal, will otherwise certainly to eliminate.”Yunnan should not only become the jadeite raw material collection and distribution center, should develop the jadeite processing vigorously, causes the entire industrial formalization,LED strip lights the batching, the modernized development.

China's jadeite carving had the glorious history, but since long, the theme nothing but is the flower-and-bird fish insect, the good fortune is happy, Goddess of Mercy big buddha. But carves the study also for a long time continues to use the tradition educational mode - - skilled worker leads the apprentice, the idea to be too obsolete.

He said: “our jade carving had not innovated, has not developed, the good theme has that many, why can't transform the thought? We need the specialized school, the specialized jade carving talented person. The work should integrate the curiosity, the modernity.”

: The LED illumination application's energy efficiency needs to unify the power to lose the consideration. The US “star of the energy” the solid state illumination standard has stipulated the illumination appliance level energy efficiency, but does not involve alone the LED driver's energy efficiency request.

As mentioned above, uses AC-DC power source's LED application to be possible to use two section of type distributed topology,LED lights manufacturer therefore possibly uses the exterior AC-DC adapter power supply. But “star of the energy” indeed contains the related list to output external power supply's standard, its 2.0 edition of external power supply standard starts in November, 2008 to become effective, under the request standard working pattern the lowest energy efficiency reaches 87%, but under the low pressure working pattern the lowest energy efficiency reaches 86%;

When this standard, the power is bigger than 100 W only then requests PFC. But in uses AC-DC in power source's LED application, must provide the higher AC-DC transformation energy efficiency, involves to factor between and so on cost, size, performance standard and energy efficiency compromised questions. For example, if uses the high grade part, lower breakover impedance (RDSon),dvb t tuners may reduce the loss and the improvement energy efficiency; Will cut the turn-on frequency to improve the energy efficiency generally, but actually will increase the system size. Such as resonance such new topology provides a higher energy efficiency, actually also increases the design and part's order of complexity.

If we will design define in the narrow power and the voltage range, then may help the optimized energy efficiency.
