Dragon solved the following problems: 1. [Pressure resistance problem: The Dragon needs to overcome the huge water pressure on the seabed. For example, the water pressure in the Mariana Trench is more than 1000 times the standard atmospheric pressure.] China successfully resisted ultra-high pressure by using a 70-millimeter-thick titanium alloy shell, and the three observation windows made of pure glass on its structure could also withstand water pressure. This showed that China's technology in the waterproof aspect of submarines had reached the forefront of the world. 2. [The difficulty of controlling the rise and fall of a submarine: It must be able to sink and rise smoothly.] Dragon solved this problem with the help of ballasting iron. The ballasting iron began to provide negative buoyancy for the submarine to sink. After reaching a certain depth, it threw away part of the ballasting iron to make its specific gravity close to the density of seawater, reducing the working pressure of the propeller. After the operation was completed, it threw away the ballasting iron again to obtain positive buoyancy. 3. ** Communication problem **: Because electromagnetic waves are seriously weakened underwater, the submarine needs to transmit information using sonar, but there is a problem in extracting sound transmission signals in different seawater environments. Dragon's domestic sound system solved this problem. Its sonar could accurately send and identify signals, and it could also explore the surrounding fine terrain. At the same time, the domestic ultra-short baseline positioning system could provide underwater positioning and navigation services, and the equipment could broadcast the exploration process. 4. ** Life support problem **: Like a space capsule, a deep-sea vehicle needs water, food, and a circulatory system to ensure that the submariners can operate normally underwater. There were two oxygen supply systems inside Dragon, which could guarantee the safety of three people for 84 hours. The novel "Flood Dragon" is equally exciting.

Caricature pollution is a significant issue. It can have negative impacts on the environment and public health.

Plant more trees. Trees can act as natural sound barriers, absorbing and deflecting noise. For example, in many urban parks, the presence of a lot of trees makes the area much quieter compared to the surrounding streets.

It's a very serious issue. Caricature environmental pollution can have significant negative impacts on our planet and all living beings.

The problem/conflict in a story can be solved in various ways. It could be through a heroic sacrifice, a clever plan, or even a change in perspective that leads to a new approach.

The 'Problem Solved' political cartoon usually conveys a solution or outcome to a particular issue presented. But its exact meaning can vary depending on the context and details shown.

He was treated really well. The fans were excited to see him and he seemed to have a great time.

Often, cartoons use vivid imagery and storylines to raise awareness about air pollution. They might depict smoggy cities or animals suffering from poor air quality to make the issue more relatable for viewers. However, the depth of the reflection can vary depending on the target audience and the purpose of the cartoon.

Well, in many cartoons, car pollution is depicted as a significant problem. It often leads to negative effects on the environment and the health of characters. However, the severity can differ depending on the cartoon's theme and message.

In a cartoon about cars pollution, it usually shows dark smoke coming out of car exhausts and maybe a polluted city scene with sick people.
