The difference between polished jade and jade
There were the following differences between water-polished jade and jade: 1. * * Elements **: - The main component of spittle jade is albite, which contains a small amount of augite minerals and hornblendite minerals. Jadeite is mainly composed of jadeite minerals, which is composed of multi-mineral minerals. The main component is NaAIsi <2> O <3>, and also contains a small amount of elements such as Ce, Mn, Ti, S, Ci, etc. 2. * * density **: - The density of the water foam jade was about 2.6g/cm 3, and the density of the jade was between 3.25 - 3.35g/cm 3. The difference in density caused the two to feel different. The water foam jade was relatively lighter. 3. Hardness: - The Mohs hardness of jadeite was 6.5 - 7, while the hardness of spittle jade was lower than that of jadeite. 4. * * Emerald Nature **: - Jadeite was green, and its interwoven structure (fly wings) could be seen under the light. The foam jade did not have this typical interwoven structure because the mineral composition of the two was different. 5. * * Internal impurities **: - Although there might be impurities in both, the form and distribution of impurities inside the jade were fundamentally different from that of jade. There was a lot of white cotton inside the water foam jade, which looked like white foam floating on the water. This was a typical characteristic of the jade. The impurities of the jade varied according to the water and other factors. 6. * * Finished Glow **: - The water foam jade had a low refraction index, and the surface luster of the finished product was dimmer than that of jade. Even if it reached the ice type, the water foam jade did not have the fluorescent feeling of jade. 7. * * Original Stone Shell **: - The raw water foam jade stone had a very thin and transparent shell. The raw water foam jade stone with a white shell was similar to the raw jade stone, but the shell of the raw water foam jade stone was close to grayish-white, and the raw jade stone was bright white. There were also raw water foam jade stones with black spots on the surface. The black spots were like stars in the sky. The sand particles were uniform, and the surface of the raw jade stone had a typical interwoven structure. On the rough surface after cutting, the surface of the water foam had a scale-like weak glass luster. The size of the flashing surface was uniform, while the jade showed a "fly wing-like" flash. The size and length of the flashing surface varied. 8. * * Floating Flower Form **: - In the finished product of the floating flower of the water foam jade, the shape of the floating flower was more three-dimensional, as if it was "embedded" in it, similar to the wrapping of the ghost crystal. The floating flower of the jade was like the ink painting melting into the base, and the color gradually changed from dark to light, which was more ethereal. The novel "Ledge" is equally exciting.

Canon lens, Nikon lens
Canon lenses and Nikon lenses were well-known brands in the field of camera lenses. In terms of Nikon lenses, the new Z-mount lenses were generally of high quality, such as holo-field compatibility and excellent corner resolution. The F-mount was limited by the caliber and the distance between the two sides, while the Z-mount had a great improvement in this aspect, especially in the wide-angle to mid-focal length section. Canon lenses, such as the RF28 - 70mm F2.8 lens, had a constant large aperture of F2.8. It was portable, and the image quality was average, even a little beyond the positioning of the silver ring lens. It also had anti-shake function.
