The key to installing the lenses is to make the main optical axis of the objective and eyepiece fall on the center line of the lens barrel, which is the more difficult part of the experiment.

Lan Jie carefully placed the objective tube with the objective lens initially installed on the light source, and more carefully covered the end of the objective lens barrel without an objective lens with a layer of translucent paper, so that the light was imaged in the center of the translucent paper through the objective lens.

This experiment should not be done with brute force, but with caution. The tall Lan Jie has delicate hands, he adjusts the objective lens at all, without slackness, his hands make the simplest telescope, and his heart flies to the sea of stars.

"Hey, Handesang, how do you adjust the eyepiece? I can't remember the actual details of the eyepiece. Zhu Mengqi, the deputy squad leader of the operation position next door to the experimental table, asked in a low voice.

Lan Jie turned his head and looked, yo, Zhu Mengqi's hand speed is very fast, I haven't finished adjusting the objective lens yet, and she has already started to adjust the eyepiece.

"Hey, pot Jisi, give me three minutes, and I'll give you back a sea of stars. Lanjie sped up the experiment and adjusted the objective lens in an instant.

Zhu Mengqi is a girl with no characteristics.

Her face is neither beautiful nor ugly, she is neither tall nor short, her figure is neither fat nor thin, her skin is neither white nor black, and her hairstyle is neither long nor short nor curly or straight.

She doesn't walk fast or slow, she doesn't speak lightly or heavily, she doesn't leave school early or late, she doesn't eat much or nothing at every meal, and her seat doesn't go forward or backward or left or right.

She didn't get top grades in any of the subjects, and she didn't lag behind in any of them.

After entering the sheep middle school, her total score will always rank in the top three in the class, to be exact, even the ranking has not changed, she will always be the third in the class.

Although it is featureless and rarely shows off highlight operations, I have to admit that Zhu Mengqi is an indispensable cornerstone of the second and third classes.

Lan Jie skillfully adjusted the eyepiece, Zhu Mengqi observed and studied for a while, she nodded and said, "Well, that's right, I remembered, the eyepiece is adjusted like this." ”

Lan Jie and Zhu Mengqi completed the assembly of the simple Kepler telescope at the same time, and the two presented the telescope to Tang Xiaoyun for review.

Tang Xiaoyun thought it was qualified after the inspection, she said: "Lan Jie and Zhu Mengqi completed the high-quality experiment in the shortest time, which is very good, you two go back to the teaching building to write the experiment report." ”

"Well, okay. Lan Jie took the binoculars and left the laboratory with Zhu Mengqi.

Lan Jie said as he walked: "I love to do physics experiments the most, and every time I finish a physics experiment, I can always take something practical with me. ”

Zhu Mengqi said: "The wool comes from the sheep, and these practical things are not included in the tuition and miscellaneous expenses. ”

"Zhu Mengqi, let's think about it differently, we don't make money by bringing goods out of the laboratory, but if we can't bring them out of the warehouse, it will be a blood loss. ”

"Yes, that makes sense, so Lan Jie, we don't make or lose money today. ”

Back in the second and third classrooms, Lan Jie flicked his binoculars, and he asked, "Guo Jisi, do you like to look at the stars?"

Zhu Mengqi stroked her binoculars, and she asked rhetorically: "Handesang, use this simple telescope to look at the stars?"

Lan Jie smiled and asked, "Of course, I use a higher-end telescope to watch the stars, are you interested?"

Zhu Mengqi asked again: "Do you have a higher-end telescope?"

Lan Jie nodded and said: "The telescope is not a problem, the key problem is the car, if the problem of the car can be solved, I will organize a free trip." Zhu Mengqi, leave a parking space for you, welcome to get on the bus. ”

The provincial middle school athletics meeting is approaching, and Lan Jie has signed up for the men's long jump, and he attaches great importance to this sports meeting.

Recently, Lan Jie has been training the long jump every day, and although some technical details still need to be improved, Lan Jie is confident that he can do well.

Ranger had the same dream for the past two days.

In the dream realm, Lan Jie stepped into the air, his feet kept stepping on the air, and the faster his feet stepped on the air, the higher Lan Jie flew. Stepping on and on, Lanjie finally stepped out of the atmosphere.

The dreams that adolescents have during the development period are often related to physical development.

On April 29, Lanjie measured his height, 186cm.

Plus one!

This centimeter is added to the leg, one centimeter is longer and one centimeter stronger, good news, God help me Ajie too!

That night, Lan Yunhui had dinner near Yangda.

After the meal, Lan Yunhui brought two bottles of sauce-flavored liquor to Lan Jie's house.

Lan Jinhui asked: "Xiaoyun, don't all members of your teaching and research department drink apple cider vinegar?

Lan Yunhui explained: "Tonight is a meal in the courtyard, and there are two bottles of liquor left, I will bring them to you by the way." ”

"Oh, eat in the courtyard, I see. I always think that it is normal for people engaged in literary and artistic work to drink some wine, how can they have creative inspiration if they don't drink?" Lan Jinhui smiled at the sauce-flavored liquor, although he didn't help his brother's sister, he helped his brother's sister.

The brother and sister chatted for half an hour, and Lan Jinhui asked Lan Jie to send her aunt.

Lan Jie sent his aunt downstairs, and her aunt's car was parked downstairs.

"Auntie, you didn't drink at the bar? Lan Jie asked with concern.

"I didn't drink. Lan Yunhui shook her head, and she said: "I have a meal every day this week, one at noon and one at night for two days, and another night supper, and then I go to have morning tea after the supper is over." The store sent some coupons, Applejack, you can use them. ”

Lan Yunhui took out a large handful of various coupons and stuffed them to Lan Jie, local cuisine, Hunan cuisine, Sichuan cuisine, Shandong cuisine, Northeast cuisine, Japanese food, barbecue, buffet, all kinds of coupons.

"Auntie, you're so busy, you're a successful person!"

"Busy. ”

"Busy is busy, aunt, you must pay attention to your body, your body is the capital of your career. Lan Jie accepted these coupons, and he said to Lan Yunhui with a grateful heart: "Thank you, aunt! If it weren't for the fact that physics is my belief and fate, I would definitely apply for the Galaxy Conservatory of Music." This is a voucher for the Garden Hotel, I have lived in Aries City for more than ten years, and I have never stayed in the Garden Hotel. ”

Lan Yunhui took back the accommodation voucher of the Garden Hotel, she said: "This kind of thing is okay but not necessary. Applejack, when you're an adult, you'll go to the hotel by yourself. ”

"Uh-huh, okay. Huh, what kind of ticket is this? Aries Theatre "Matilda"?" Ranger swiped the last two tickets, which were tickets for the Aries Theatre on the night of May 1st.

"I personally prefer the West End to Broadway. Matilda on the night of May 1st is the West End version, Ajay you can check it out. As a music teacher, Lan Yunhui hopes that Lan Jie will come to the theater to enjoy the musical, so as to improve his artistic accomplishment and cultivate noble sentiments.

"Well, I especially like art, this West End version of Matilda, I won't miss it, thank you again aunt!"

Ranger waved goodbye, and his aunt drove away.
