Professor Ye Hong calmly asked, "what's going on?"

Xu Siyu pursed his lips and said, "the X7 material I saw in a material department magazine is integrated with many substances, so it is directly used."

Ji pomelo smiled and said, "but do you know what? What really blends with many substances is not X7 material, but R7 material subdivided after X7 material is dissolved in water."

Xu Siyu opened his eyes slightly.

The faces of Ye Hong, Jiang Yulan, and several other teachers became more and more ugly.

Ji pomelo smiled and then: "The reason why you don't know is that you use water-soluble when making materials. After X7 water-soluble, you naturally get some R7 to support you to complete the experiment. However, due to the influence of the proportion, temperature and humidity of various materials, the R7 content dissolved in water is unstable, high or low, which makes your experiment fail and succeed."

With Ji You's explanation, except for Chu Jiaojiao, Shen Changqing and Yue qiguang, all the students and teachers of the materials department present understood Ji you.

Everyone opened their eyes and looked at Ji pomelo.

Ji pomelo's speech was slow, word by word, clearly spread to everyone's ears: "the key factor to maintain the stability of R7 material is S53 material."

In the face of people's skeptical eyes, Xu Siyu's face turned white. She pursed her lips and said, "I know what you said. I've done countless experiments, of course."

"Oh?" Ji pomelo raised her eyebrows and asked with a smile, "sister Xu Siyu, my Ji pomelo looked at Xu Siyu and whispered: "Actually, it's different. Because the manuscript I borrowed and destroyed by Xu Siyu still lacks antecedents and conclusions, the reason why I began to study materials in middle school was because I knew that my talent was low. Only learning materials was the way out of the junk star, and I began to study xingcao at that time I decided my future path and began to do it. I found that when I studied ordinary plants such as xingcao, this process brought me great fun... "

"I made some achievements. At that time, I didn't know that it could combine the two methods of processing materials. At that time, it was just a rough idea. I told my deskmate Xu Siyu the joy I found. She was very interested. After that, she always cared about my experimental progress. Until I really succeeded, she was very happy and said that she would join me Research, I borrowed my manuscript notebook by the way, and then... "

"It's a pity that Xu Siyu never gave it back to me. She explained to me that it was accidentally lost." Ji pomelo looked at Xu Siyu, smiled on her lips and asked, "sister Xu Siyu, do you agree with my above words?"
