How about Mazda CX-4? The value of power consumption is both controllable, but it also has shortcomings. The bigger drawback is that

Mazda CX-4's shape design is perfect, high grade, not like the mid-level car, especially the standard LED star shooting eyelight design, at night, it has the feeling of high-end car. The body line CX-4 is also smooth and perfect, and the interior design is also OK, which is quite satisfactory. The engine is also perfect, power output to force. The performance on fuel consumption is also very surprising. The fuel consumption is very low. The blue sky body, the blue sky chassis and the blue sky engine are all created. These high-tech technologies have reduced the fuel consumption of the CX-4.

CX-4 comprehensive performance is OK, but there are also shortcomings of poor performance of tire noise and sound insulation. After 60 yards of noise will increase, this price of Japanese cars, it is estimated that this problem, do not want to install sound insulation, car It will be very distressed to be dismantled, and the space of the CX-4 is still a bit narrow, which is one of the bigger drawbacks.

The space is not large. As a compact SUV, the space of the CX-4 is enough, and the storage space is OK, but the ride in the back row is still relatively poor. The space in the back row is very small. My friend and woman. 3 people, sitting in the back row is OK, is the middle raised, uncomfortable, men's words, if you have a big head, you can only sit 2 people, the trunk is still considered qualified, not too big or too small, normal use is enough .

I am a sister paper, I am not demanding power. The CX-4 engine is a blue sky technology. The acceleration is very stable, the start is very fast, the corner is also very stable, and the performance is not bad. The chassis is solid, the steering wheel is also comfortable to operate, not too light and not very good, and the steering is very easy. The power of the CX-4 is abundant, and it will open to 100 and 120 on the elevated platform. The car is still quite stable. Look at the speed of the instrument panel and then slow down. The performance of the 2.0L car is already good. If you are a friend who likes to drive by yourself, it is better to choose 2.5L, and it will be easier to get on the high speed and ramp.

Mazda's control is still good, the CX-4 is very good, the car is not too big, it is also good to stop, the steering wheel points to the precision, which is where to play. Because it is SUV design, the passability is also good, the suspension is hard to train, the sport style is good, the cornering support is good, and the body is very stable.

CX-4's performance in fuel consumption is excellent, fuel consumption is very low, Japanese cars are inherently fuel-efficient due to the weight of the car, CX-4 uses the world's most advanced Chuangchi blue sky engine, Chuangchi blue sky chassis, create As for the blue sky gearbox, the fuel consumption is even more economical, but the power does not affect it at all. At present, it has opened several hundred kilometers and the fuel consumption is around 7.8. The driving feeling is very good. I am also very good at driving. I usually do not drive violently. Basically, there are still a lot of elevated roads. The CX-4 feels very good when it is opened. It is also fast, overtaking, and the safety of the car is also very high.

CX-4's seat is soft and moderate, and the package is also good. Sitting inside the CX-4 is quite comfortable. It won't hurt when you drive for a long time. The noise is good. The CX-4 is generally good. The Japanese car is here. Convenient performance is not as good as the German-American car. In terms of space, as a compact SUV, the CX-4's performance in space is also general, but the home is also sufficient. It is quite convenient and easy to open, and the space performance is also Good, the cooling effect is good, the advantage of the CX-4 is up, it is easy to drive, the parking is good, I am quite satisfied with the comfort.

I was attracted by the shape of the CX-4. At first glance, the CX-4 feels that this car looks good, especially the front big face LED meteor eye headlights, very bright, the overall CX-4 shape design is domineering, soul movement, The whole car looks perfect, and the tail design is also good. In the price of 10 million, the CX-4's shape design is quite unique. It has high recognition, smooth body, soul shape and shape. Still quite like it.

CX-4 interior design is quite perfect, the materials are also good, the workmanship is exquisite, the design of the instrument panel is novel, the cool, the center console is also beautiful, the interior of CX-4 is more in line with the aesthetics of young people. The odor is not too big, the seat is good, the package is good, the comfort is high, and the sound effect is just good.

In fact, the most important thing to buy CX-4 is the engine, chassis and gearbox. The three major hardware of CX-4 are imported from Japan. The quality still makes me feel at ease. The configuration is also good. One button starts. Electronic hand brakes, LED headlights and other configurations are standard. Overall, the CX-4's configuration is still very high compared to the same price of the car, the control is also very good.

Optical Ball Lens

We all know that the convex lens has the function of condensing and magnifying light. The reason is that the refractive index of glass and air are different. If the convex lens is deformed into a spherical shape as shown in the figure, it becomes a ball lens. The ball lens has a larger magnification than the ordinary convex lens. , But the magnification of a single lens is determined by the refractive index of the lens itself. We know that the greater the curvature of the convex lens, the shorter the focal length, so ball lenses have a shorter focal length than ordinary convex lenses.

Fused Silica Ball Lens and hemispherical lens have high transmittance between 200nm and 2.2μm, and low thermal expansion coefficient, making it an ideal choice for the most stringent ball lenses in ultraviolet, visible and near-infrared spectroscopy applications. Ball lenses are commonly used to improve signal coupling between optical fibers, transmitters, and detectors, as well as objective lenses in endoscopes and barcode scanning applications. The hemispherical lens can simplify the integration of the entire system.

Sapphire and ruby ball lenses are composed of alumina ruby or ruby-doped sapphire to purify chromium oxide (the chromium content in the ruby ball must be greater than 0.5%), and their physical and chemical properties are the same, but the optical properties However, there are some differences. Sapphire has a better optical transmittance, and ruby is easier to see, so it is suitable for physical applications.
