Shen Wanqing looked at Lin Yuan seriously and asked, "What can you do?" ”

Unexpectedly, Lin Yuan laughed twice and said, "I thought about it carefully, I haven't invited you to eat since we met, and today is the first meal." ”

Shen Wanqing didn't expect what he said to be these, and thought, "Why are you joking about such an important matter!" So he said angrily: "You ......" but as soon as the words came out, he couldn't bear to reprimand him, and quickly changed his words: "You don't have to ask for so many dishes!" What a fee! ”

Lin Yuan said with a smile: "How can you catch a big fish without a little capital, let's eat it for a while." ”

The two ate for a while, and Lin Yuan shouted outside the door, "Man, come on." ”

The guy hurriedly pushed the door in and said, "Master, what's the matter with you?" ”

Lin Yuan said with a smile: "Your dishes are well done, I have a habit, when I see a restaurant where the dishes are well done, I must talk to the shopkeeper and invite your shopkeeper to come." The guy saw Lin Yuan's generous move, and knew that this person was either rich or expensive, and making friends with such a person would be very beneficial in the future, so he went to call the shopkeeper, and as soon as the guy left, Shen Wanqing said: "It turns out that you are so generous, just to see the shopkeeper." ”

Lin Yuan smiled: "Of course, otherwise the shopkeeper won't bother to pay attention to us." The shopkeeper was Hu Liang, and he also knew the benefits of the powerful, so he walked into the house in three steps and two steps, and said with a smile: "The shopkeeper is the one below, surnamed Hu Mingliang, I don't know the name of this master?" ”

Lin Yuan said with a smile: "My surname is Zhang Wenyuan, I traveled here with my wife today, and I saw that your store was good at wine and food, so I would like you to come up and talk about it, and I hope you will forgive me for the abrupt place." ”

Hu Liang sat next to Lin Yuan and chatted a few words, and Lin Yuan smiled and said, "Is the eighteen stars and moon Bodhi on Mr.'s hand?" ”

"Eighteen sons of Xingyue Bodhi" is a kind of Buddha beads, "eighteen sons" refers to eighteen Buddha beads, "Xingyue Bodhi" is a kind of plant seeds, because the pattern on it is like the stars holding the moon, so it is named, it is a precious material for making Buddha beads.

It turned out that when Hu Liang gave his hand, his sleeves fell off, revealing his wrist, and Lin Yuan saw the Buddha beads, Hu Liang looked at the Buddha beads on his wrist, and said with a smile: "I didn't expect Brother Tai to also understand Buddhism." ”

Lin Yuan said with a smile: "Buddhism is boundless, a layman in the mortal world, where can he dare to claim to understand Buddhism, can Mr. lend me the Buddha beads?" ”

Hu Liang hurriedly took off the Buddha beads, held them in front of Lin Yuan with both hands, and said with a smile: "This Buddha bead was begged by my mother from Guoqing Temple on Tiantai Mountain, and my younger brother has always carried it on his body, and he has never dared to take it off." ”

Lin Yuan took the Buddha beads with both hands, looked at them for a long time, and then asked, "Can you open your eyes?" Hu Liang hurriedly said: "Of course, of course." ”

Lin Yuan put the Buddha bead in front of Shen Wanqing and said, "Take a good look, how good this Buddha bead is." ”

After watching it for a while, Lin Yuancai respectfully returned the Buddha beads to Hu Liang, and said with a smile: "Thank you, there is still something to do, so I will retire." ”

The two exchanged a few more polite words, and then Hu Liang sent Lin Yuan and Shen Wanqing out, and Shen Wanqing asked in surprise: "Do you know Buddhism or something?" ”

Lin Yuan smiled "hehe" and said, "I don't understand!" ”

Shen Wanqing said: "You don't understand? You don't understand, how do you know that the string of Buddha beads in the Tao is called 'Eighteen Sons of the Stars and the Moon Bodhi'? ”

Lin Yuan smiled: "I don't know its real name, I've only heard that name, so I said it, he wants to please me, even if I don't say it, I will treat it as right." ”

Shen Wanqing smiled: "You are really cunning, but we are here this time, except for eating and chatting, what are we going to do?" ”

Lin Yuan said, "Have you forgotten what he said? He said that he had been carrying the beads with him, and I came to see him just to find something that he had been carrying, but I happened to find the beads, and we put the bugging device in the beads, so that wherever he went, we could hear his conversation. ”

Shen Wanqing said: "Your idea is very good, but how can we put the bugging device in it?" Lin Yuan said: "We can make a hole in the surface of the Buddha beads, then put the bugging device in it, and then glue the surface together, without knowing it." ”

Shen Wanqing said: "This kind of technique is not difficult, I can do it, and we also have miniature bugs, but the most difficult thing is how we find the identical Buddha beads, not only the appearance must be the same, but also the weight must be the same, otherwise, the things he often wears, you will know the Tao as soon as you change it." ”

Lin Yuan said: "The feeling in my hand is very sensitive, it has a few catties and a few taels I have almost written down, we can balance the weight when installing the bug, as for the appearance, as long as it is similar, I don't believe he can remember the characteristics of each pattern." ”

Shen Wanqing thought for a while and said: "That's right, even if it's different, it doesn't really matter, people in this era, who would have thought that there was a bugging device in a Buddhist bead?" Even if he noticed a change in the beads, he would think that he was feeling wrong. ”

Lin Yuan said: "Didn't I just let you see the Buddha beads? I know that your memory is very good, so please bother to go to the place where antiques are sold and look for it, Beijing's Xiangshan is a famous Buddhist mountain, there are many temples on it, maybe there will be inside. ”

After the two discussed, Lin Yuan rushed to Tianjin, he knew that the airborne radar had been transported at this time, as soon as he entered the Machine Bureau, he was led into the secret research and development department, originally the Machine Bureau did not have this department, because their skills are too backward, backward to the point that foreigners disdain it, since Luo Chaoying entered the Machine Bureau, Lin Yuan has established this department.

As soon as he entered the R&D room, Lin Yuan saw Ma Zhiliang, a radar expert on the Beijing ship, who was an old man who had participated in the design of almost all types of radars, and was also the founder of China's development of ultra-wideband radar, lidar and other new concept radars, and his monographs were almost a compulsory course for every radar designer and engineer.

Lin Yuan asked, "Ma Lao, do you know what we need to design?" ”

Ma Zhiliang frowned and said: "Our airborne radar is a phased array system, and the change in beam direction is achieved by changing the phase of the beam. ”

Lin Yuan nodded, Ma Zhiliang said again: "You are a pilot, you are certainly no stranger to the working principle and use environment of radar, because the earth's surface is a curved surface rather than a plane, and electromagnetic waves can only propagate along a straight line, so the radar can only detect targets within a direct visual distance, although there is over-the-horizon radar, the use of electromagnetic waves in the ionosphere reflection can achieve over-the-horizon detection, but this requires the radar to work in the longer wavelength band, and our airborne radar works in the shorter wavelength C-band, Obviously not that way. ”

Lin Yuan said: "I understand that the radar range is limited by the surface of the earth, in order to be able to detect long-distance targets, our radar must be set up at a high place, do you want to talk about this problem?" ”

Ma Zhiliang said: "That's right, it's better to let people wait for equipment, not let equipment wait for people, I think now we should think about the location of the radar, I just looked at the map, the best positions seem to be occupied by their gun positions, should we drive them away?" ”

Lin Yuan shook his head again and again and said, "This is absolutely not good!" ”
