In the evening, Zhu Qi finally arrived in Ping'an County after an afternoon of traveling, and after greeting Wang Lei and Hao Shao, the three of them chatted in the living room. Pen "Fun" Pavilion www.biquge.info

At the dining table in the living room, Wang Fugui was looking at Ouyang Yue excitedly, and now his baby radio direction finder was letting Ouyang Yue fiddle.

After Ouyang Yue accompanied Zhang Hongying back from grocery shopping, she saw Wang Fugui fiddling with the radio direction finder at the dining table, Ouyang Yue knew for the first time that the radio direction finder in his hand was from Wang Lei's handwriting, so she said out loud: "Radio space spectrum estimation direction finder!" ”

Although Ouyang Yue's research direction is not radio, but she still knows something about these things, but Wang Fugui on the side doesn't understand, during this time he has been studying this direction finder for a long time, but there is no progress at all, and now someone actually said the full name of this instrument at once, he was naturally very happy, so he stopped Ouyang Yue and desperately asked everything about this direction finder.

Seeing someone asking, now that he has nothing to do, Ouyang Yue is naturally willing to give people answers, so Ouyang Yue sat at the dining table and introduced to Wang Fugui while demonstrating: "Space spectrum estimation direction finding is a new type of direction finding technology based on multiple antenna arrays combined with digital signal processing technology, it is the measurement of the direction of electromagnetic signals, that is, to measure the same phase wavefront of the electromagnetic wave incident by the radiation source, so similar to the traditional direction finding system, the entire space spectrum estimation equipment system is composed of three parts, namely the space radiation source, Spatial receiving arrays and algorithm processors. Spatial spectrum estimation direction finding is not to directly calculate DOA from the concise mathematical formula of the signal amplitude or phase received by each antenna element, but to estimate the spatial frequency ...... according to the output signal of each element for the general far-field signal, for the general far-field signal, there is a wave range difference between the same signal to different antenna elements, which leads to the phase difference between the receiving elements, and the azimuth of the signal can be estimated by using the phase difference between the array elements,......"

Soon, Ouyang Yue's science lecture began at the table, although Wang Fugui was the only one who listened, but Ouyang Yue was still very happy.

……

After the sun set, Zhang Hongying's voice came from the kitchen: "It's time to eat!" Dinner! Wang Lei, stop talking, come in and help me serve food! And the two at the dinner table, please take the things off the table, we're going to serve the food! ”

Under Zhang Hongying's greeting, a group of people in the family began to get busy and serve food.

As early as when Zhang Hongying entered the kitchen to cook, Hao Shao and Zhu Qi, who thought they could cook, were a little reluctant to see Zhang Hongying busy in the kitchen alone, they wanted to help, and then they were kicked out by Zhang Hongying as a matter of course.

It's not that Zhang Hongying is polite, it's just that she thinks it's completely unhelpful to let them in, and now the kitchenware and cooking utensils in the kitchen are all high-tech products, and they can't understand it when they come in. And now the housekeeping robot is now in the kitchen, they come in, the housekeeping robot can only be disguised as a box, and nothing can be done, and Zhang Hongying does not think that their efficiency is as high as that of the housekeeping robot, you must know that the housekeeping robot cooks a potato, and it only takes one second from peeling to slicing.

In fact, in the kitchen, the selection of vegetables, washing, cutting, stir-frying, washing dishes, etc., these jobs have been contracted by housekeeping robots, Zhang Hongying cooks just to control the heat of stir-frying, the amount and time of seasoning, and when to add what ingredients in the cooking process, these procedures can be completed by housekeeping robots, but in Zhang Hongying's cooking process, the food is required to put something when it is a little cooked, and the food can be out of the pot when it is a little cooked, there is no such function, so it can only be controlled by Zhang Hongying herself.

After the meals, bowls and chopsticks were ready, everyone was ready to eat, when Zhang Hongying suddenly thought of something and shouted towards the stairs: "Jiahezi!" Come down and eat! ”

After Zhang Hongying shouted like this, Wang Lei finally remembered that there is such a number one person in the family, no wonder he always feels that something is missing from the beginning of the dish. This princess has only been in the house for a few days, and she rarely talks to each other, and it is easy for people to forget her existence.

And Hao Shao, who was sitting next to Wang Lei, showed a thoughtful expression when he heard Zhang Hongying call "Jia Hezi", he always felt that this name was weird, and it seemed that he had heard it somewhere, but he couldn't remember it all of a sudden.

As soon as Zhang Hongying's words fell, Jia Hezi walked down from the upstairs, and after seeing so many people, she immediately lowered her head, slowly walked over to find a place and sat down by herself, and she didn't say a word from beginning to end.

Jiahezi's attitude is largely because of Wang Lei. I don't know what Jiahezi's personality was before, but after being controlled by the memory control chip, Bai Xue input a lot of loyal thoughts to Wang Lei in her mind, and deified Wang Lei in her mind, every time she saw Wang Lei and everyone in the family, she had a feeling of being a saint, and she could already praise her cultivation without trembling.

Hao Shao has been staring at her since Jiahezi came down, and Hao Shao has been trying to pull out the memories of Jiahezi from the depths of his memory. Because of the characteristics of his work, the people he came into contact with were either the high-level of Yan'an or the enemy's spy spies, and the only people who could make him have an impression were these two kinds of people, and there was no such strange name among the high-level people in Yan'an, then she might be a spy agent, and for the safety of the instructor, he also had to remember who this Jiahezi was.

At this time, Wang Lei noticed the strangeness of Hao Shao next to him, and he patted Hao Shao's shoulder: "Falcon No. 1, what's wrong?" Although he already knows Hao Shao's name, Wang Lei is used to calling him by his code name.

Hao Shao shook his head: "It's nothing! I just think that the name Kawako seems to have been heard somewhere! He didn't say his guess, after all, he didn't know what the instructor had to do with this guy named Kawako, and it wouldn't be good if the instructor had any misunderstanding.

Wang Lei didn't think much about it, he was just a little curious about how Hao Shao would know Jia Hezi's name, after all, their identity environment should not have any intersection before.

Just when Wang Lei was about to speak, Zhang Hongying spoke: "Okay~!" Wang Lei, eat first, you can talk while eating! Otherwise, the dish will not taste good when it gets cold for a while! ”

Hearing Zhang Hongying say this, Wang Lei smiled: "Let's eat!" Dine! Saying that, he picked up the chopsticks and put some food for himself, and when he saw Wang Lei, the active chopsticks of the family, everyone began to pick up the chopsticks and eat, and the meal finally began.
