That is to say, the bridging mode further abstracts the implementation details of the original base class into an implemented structure, and then transforms the original base class into an abstract hierarchical structure, thus realizing independent changes of the system in multiple dimensions. The structure diagram of the bridging mode is shown below.4. "Towing lamp" means a yellow lamp having the same characteristics as the "tail lamp" mentioned in paragraph 3 of this Article."Then it was the old method of tracing armour-piercing firebombs that repelled the attacks of the big wasps twice. There was another very special sound from the position. At first we thought there was another big wasp coming, But after looking at it for half a day, I didn't find anything. After a little while, It is also the kind of special sound that is getting closer and closer. Only then did I recognize that it was not the "buzzing" sound of the big wasp, But a sound of "knowing, knowing, knowing, knowing, knowing, Taken out with 'creaking', It's like a lot of people grinding their teeth together, Then a piece of black came running in the direction of the position. This time the direction is straight ahead, At first those things were far away from us and we could not see them clearly with our naked eyes. It was an instructor with a telescope who looked through the telescope and saw that the thing was a lot of mice. And they are all very big, After the news spread throughout the position, I have all my comrades, All ready for battle, Knowing that this is like one of those big wasps, It is certainly not a good fault, Just thinking of starting to fight the newcomers when it comes closer, I didn't think they were about 100 meters away from the position. It stopped suddenly, At the beginning of digging holes collectively, I felt that they were digging holes faster than running on the flat ground. One by one, they almost disappeared from the ground in an instant. Soon, a large area of dark mice disappeared. Looking through binoculars, on the ground where they disappeared, there were many holes the thickness of sea bowls, which were almost denser than craters.未曾见过的，命运交错的恋爱喜剧，就此开幕！But we didn't realize it until the first big mouse emerged from the trench of the position. The big rats under the "earth beam" are only a few that dig shallow holes. Most of the deep digging is simply not visible from the surface, This is what I said just now. If you dig shallow, you can barely hit it. You can't see it deep, There is no way out, At last this thing was dug up and emerged directly from the trench wall. Then don't even shake the soil on your body, Bite at the sight of men, As the number of drillings grows, In the end, there were several times more rats than people in the position. Forming a situation of several besieging a soldier, Seeing the urgency of the situation, But 'the lame man caught up with the uneven road' (this is a folk proverb, meaning to make things worse, the house leaks when it rains at night), The big wasps that were repelled for the first time launched another attack, or from the left and right wings, in your words, this also formed the "open space" to cooperate in the battle. It is very strange that the big wasps did not attack the big rats on the ground at one time, but only stung people. They are obviously "a group" of dogs. Alas, then we will fight too badly. " Zhang Xiaobo said with a long sigh here, and I couldn't help but be surprised. This big mouse can dig out more than 100 meters of passages underground in more than half an hour. How fast is this? That's a speed of more than 30 centimeters per minute. Although it is said that the soil on the southern border is softer and no harder than that in the north, it can dig more than 30 centimeters per minute. This speed is really staggering.
