Jing Dong is very straight

Keep in mind our website and wish you all a happy reading!Don't forget to spread the word.

Hearing the word Xiaohua, Jing Shuyun raised her eyebrows lightly, her eyes rolled on Tang Qiubai's face, she was thinking, and her thin lips parted slightly for a moment, "Does Miss Tang have WeChat?"

What!This is the first time I was asked by a young lady on WeChat!Help!

"Yes..." Tang Qiubai's hand holding the phone was a little stiff.

"Ah."

Jing Shuyun took out the mobile phone in her bag, raised her eyes to meet Tang Qiubai's innocent and dull eyes, and the tip of her eyebrows moved slightly.

Tang Qiubai, who was belatedly aware of it, received the eyes of the other party who was in a hurry, and quickly unlocked the phone and handed over the QR code with both hands.

Tang Qiubai looked at the screen, nicknamed a single word scene, with a white background, and a big head portrait written with the word work, feeling a little confused.

"Miss Tang, I have something else to do."

Tang Qiubai responded repeatedly, "Okay, Director Jing, please go slowly."

"Well, the rice cake is gone." Jing Shuyun lowered his head and shouted.

Rice cake?who?

The assistant standing behind Jing Shuyun bent down to pick up Xiao Hua and Tang Qiubai nodded slightly, turned and left.

"..."

Chapter 4

Tang Qiubai walked into the office with breakfast in hand, and within a few steps, a small blackboard was pushed to block her way.

She glanced at the blackboard and bypassed it. Every time a new task was assigned, she would paste the printed task list on this small blackboard, so that the corresponding personnel could check it by themselves.

Duan Tianyu, who stood in front of the blackboard with a sad face, followed behind her, "Our team has entered a large number of orders."

Tang Qiubai nodded.

"Is it still the old rule, you do the original suction, and I do the atomic fluorescence?" Duan Tianyu asked.

"it is good."

Tang Qiubai finished his breakfast quickly, looked at the words on the blackboard, and called Xia Sen into the laboratory with a notebook of experimental data.

The laboratory is just opposite the office, not far away, just to prevent unrelated people from entering without permission. Most of the time, the door of the laboratory is closed, and the experimenters need to enter the password when they need to enter.

After changing the lab coat and wearing gloves and masks, Xia Sen went to wash the utensils needed for the experiment first, while Tang Qiubai turned a corner to get the samples.

"Qiubai, I have released the samples you brought back from Lanhua yesterday to the drying room." Zhou Chen is the sample manager of the laboratory.

"Okay, trouble."

The newly brought back solid samples need to be placed in the air dry chamber first, and the air dry for a period of time before the experimental analysis can be carried out.

After taking the samples, Tang Qiubai went straight into the balance room, where Xia Sen was already waiting for her.

"Xiaoxia, you come to weigh the sample today, and I will check your learning results." Tang Qiubai handed her the sample in his hand.

"Okay, Master."

Xia Sen took the sample and put it aside, probed, and looked down at the level bubble from directly above the balance. She was a little off, and she adjusted the leveling feet of the balance with both hands. After a slight adjustment, the level bubble returned to the central position.

After adjusting the balance, Xia Sen went to the dryer to take the calibration weight for self-calibration. The calibration weight must be moved with tweezers. This is what Tang Qiubai said, and Xia Sen remembers it very clearly.

After the calibration was over, Xia Sen officially began to weigh. After folding the weighing paper twice, it was gently placed in the balance and adjusted to zero.

The heavy metal weighing spoon had to be made of wood. Xia Sen held the wooden spoon in his right hand and scooped it up little by little, while the other hand patted lightly on the wrist holding the wooden spoon.

"Soil No. 1 is 0.2001g." Xia Sen said.

"En." Tang Qiubai nodded slightly and recorded the data.

"Parallel sample No. 1 0.2001g."

The weighing of soil samples needs to be accurate to the fourth decimal place with a ten-thousandth balance. Tang Qiubai's request is that no matter whether the samples are parallel or parallel, the fourth decimal place of the sample weight must be similar.

It's easy to say, and it seems that Xia Sen also thinks it's easy, but when Tang Qiubai asked her to do it by herself, she realized how fickle the balance is. It was just right for a second, stabilized for a few seconds, and then quickly jumped away. .

Xia Sen calmed down and came patiently. Later, seeing that Tang Qiubai did a lot, he learned how to do it himself.

"Master, the weighing is over."

"it is good."

While digesting the soil samples, Duan Tianyu shouted from the other side:

"Qiubai, do you still use a hot plate?"

"Well, it's okay, you can use the microwave."

With a "click", Tang Qiubai turned on the electric heating plate to adjust the temperature.

With the advancement of science and technology, with advanced instruments, many experimental operations are more convenient.However, in order to pursue more accurate data, Tang Qiubai still occasionally uses relatively complicated traditional methods.

Of course, these were just the tip of the iceberg. Later, when Tang Qiubai took her through a whole set of experiments, she realized how rigorous Tang Qiubai was about the experiments.

Xia Sen looked at Tang Qiubai's serious look, and recalled the scene when he first came to this company to meet her.

There were a lot of interns, so the company specially held a meeting to assign the interns in detail. She and other interns moved chairs and sat in the back row, while regular employees sat in the front row.

Director Cheng was having a meeting, and everyone recorded in their notebooks that Xia Sen was sitting in a position where he could see the owner's notebook in the front row through the gap in front of him with a slight tilt of his head.

After she finished writing a line, she looked up and saw a page full of graffiti on the book in front of her.

"Okay, let me talk about the assignment of interns, Xia Sen."

"Here." Xia Sen retracted his eyes and got up.

"Little Tang, bring it here."

Following the direction of Director Cheng's eyes, Xia Sen saw the senior named Xiao Tang sitting obliquely in front of her standing up, closing the graffiti notebook, "Okay."
