Tencent Digital (Zhong Wenze) Samsung in the high-end market can not be satisfied with the iPhone and die, after all, iOS has obvious advantages. Therefore, this South Korean manufacturer opened up new trails and developed a model that is completely aimed at the Chinese market - a flip-type dual touch screen mobile phone.
In fact, this phone is certainly not as good as millet hammer Huawei Meizu, did not want to do video, but this flip machine is like a physical keyboard phone, you do not do, after the chance is probably not done. So by feelings, I did a video evaluation of this phone.
Dual-screen practical value is high?
Flip phone Andrews how to design the three virtual keys?
Does the hardware meet the price?
Cylindrical lens is mainly used to change the design requirements of imaging size. For example, convert a point spot into a line spot, or change the height of the image without changing the width of the image. It can be used in linear detector lighting, barcode scanning, holographic lighting, optical information processing, computers, and laser emission. Optical cylindrical mirrors are also widely used in high-power laser systems and synchrotron radiation beam lines. At the same time, the requirements for cylindrical mirror parts are getting higher and higher, especially in the cavity of high-power laser resonators and long-distance line interference. High-precision testing instruments and devices such as instruments.
