The peach blossoms in Weishui bloomed again, and the old man Wang Xiaotong from Liaodong sent an urgent letter over. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 The info problem is neither big nor small.

The new blast furnace of the Shicheng Iron and Steel Plant blew up.

Selling one in a Bethelman-style blast furnace is nothing, which is something that Zhang De has long been worried about and looking forward to at the same time. As long as Wang Xiaotong and Wang Xuedi did not die, the death of a few Khitan slave laborers was nothing.

The problem is that human life cannot be filled in vain, and people have to think about why the blast furnace is exploding.

According to his observations in the past few years, the author of "The Ancient Calculations" said to Zhang Dexin: "The new furnace of Wuguan No. 3 has been around for a long time, and its iron material of coal concentrate has slightly changed from the old furnace of No. 1 and No. 2. The coal is produced by local coking, but the source of the iron is different. The old materials are the Youji Liao Metro Mine, and the materials transported by the Dahe Cave Brother are very little fluorite. However, the No. 3 new furnace is the product of Qilu's old ironware, and the mineral contains fluorite ......"

Shaking the envelope, Lao Zhang slapped the letter paper on the table, and then slapped his palm, full of emotion.

In fact, Mr. Wang Xiaotong is not funny, he still uses a data table to speak. The comparison between the ore and nail output rate of the local iron ore in Youji and the production in Denglai Shandong was listed, and the source of iron was sorted and the primary file was established.

To tell the truth, one thing that Lao Zhang has always admitted in his two lives is that none of those who play mathematics are in vain.

The hierarchy of admiration for engineering dogs is about the mathematician-physicist ------ engineering dogs.

"Everything will change through the ages, only mathematics will not change, and only mathematics will not deceive people."

Zhang De muttered to himself with some emotion, and then hurriedly went to the study, passed by the side compartment, and called, "Sanniang, come and help me polish the ink." ”

"Yes, here it is."

Putting down the needle and thread in his hand, there was a little bit of clothing and cloth in the basket, obviously busy with delicate work. Bai Jie is a woman with delicate hands, different from Zheng Wan's unrestrained faction, she is a typical scheming 1,500 years later, and she is very open in the Tang Dynasty.

The only pity is that this woman smashed the pot in Zhang Caozhi's hands, and it is impossible to correct it in this life.

Originally, Bai Jie still wanted to rely on her posture and temperament to speak, but she didn't know that the Liangfeng County man who was bored and did her had actually had someone outside and gave birth to a son.

It can be said that if the scheming knew the reason why Zhang De was so "indifferent", I am afraid that he would only complain that Zhang De and Zhang Caozhi were a scheming boy.

Although she has always shown people with a gentle posture like water, she has never been slow down in what Zhang De commanded.

After a while, Bai Jie, who had laid out the rice paper, saw that Zhang De had already worked hard to write, she glanced at what Zhang De had written, and then the whole person was stunned.

She knew every word, but when it came together, she had no idea what bullshit it was.

Of course, there are also those who don't know...... But that's not important, there are few people in Datang who know each other, except for the students of the engineering dog and the students of Wang.

Mr. Wang Xiaotong knows the benefits of coking, but he doesn't know why coking coal is stronger than wood. Lao Zhang didn't talk to him about thermodynamics or energy, but introduced a concept to the old man - temperature.

Therefore, on the day when the peach blossoms bloomed in Weishui in the ninth year of Zhenguan, the author of "The Ancient Calculations" defined the solid-liquid mixed temperature of water at a standard atmospheric pressure as zero degrees.

Then the old man thought about it and added a stroke: if the water is boiled, it will be a hundred degrees.

As for what iron ore sorting work, the active ingredients in iron ore, and the color classification of iron ore, these are all details...... Anyway, no matter how you do it, the new blast furnace still has to be fried a few times.

Of course, after writing it, Zhang De's hands were a little sour, and after packing the envelope, he asked people to send it to Shicheng Iron and Steel Plant quickly.

"Ah Lang is a little tired?"

Bai Jie blinked and looked at Zhang De with half-closed eyes a little playfully. Typical scheming eyes are talkative, and they only talk about love. In short, their eyes are seductive......

Lao Zhang originally said that he was a little tired, and he was tired and broke his waist on Zheng Wan for a while, and he had to clock in and go to work every day to deal with technical problems for Li Dong.

But when I saw that the three ladies were as warm as water, and she looked weak and deceitful, a restless firework suddenly floated in her heart. I just want to peel off the petals of this delicate flower.

Zhou Dunyi said, "Slim and elegant, not vines and branches", and said "You can only watch from a distance, but you can't blaspheme and play", but the vulgar Zhang De thinks that Lao Zhou's words are not scientific, normal young men, don't they just want to "play profane" and pat their butts and leave?

Aristocratic demeanor, proper.

The spring peach is in the wind with calyx and seals the buds, and the juicy young girl, with a little dress, will have fragrant hormones to the male dog's brain to give mating instructions.

Not to mention that this woman is not only full and juicy, but also fair lady. The robe faded, and the snow-white body, which was as soft as silk, was just allowed to be placed on the desk by the strong man.

Crash!

When the evil fire came up, where could it be suppressed, Zhang De untied his belt and swept the pen, ink, paper and inkstone on the desk. Bai Jie was startled, it was probably because the weather was still cool, Zhang De took an arrow step, held the study door with both hands, and shouted left and right: "I have something important, don't make noise!" ”

Boom!

The door was slammed shut, which eliminated the cool breeze at the end of spring and added warmth to the house.

"Aaron ......"

Somehow, Bai Jie saw that Zhang De was like a tiger and a wolf, so he was even more interested, like a rabbit who didn't know whether to live or die, and the jackal, tiger and leopard who came to hook coveted it.

Speaking of which, the orchid girl who scratched her head in Pingkangfang, Ren Er and others teased in every way, and Zhang De didn't think there was anything new.

It's just that this white third lady, who dresses dignified on weekdays and strips off the bed repeatedly, really doesn't feel tired no matter how she plays.

"You goblin, don't I know you're flirting with me? See how I clean you up! ”

After that, he took off the brocade robe and put it on the desk, Bai Jie's snow-white body rolled down, the whole person was delicate and delicate, like a lamb to be slaughtered, Bei Yan bit his lips lightly, his eyes were full of tears, and he looked like he wanted to cry and shout, and he wanted to die and grieve.

The more this goes, the more evil it is.

The old man opened his mouth and shouted, but his hands and feet were not slow, and his eyes were more like swords plowing the ground, back and forth on this white silk body. This woman is also a lot of money, and she is definitely not lacking a little plumpness. Compared with Zheng Wan's hot and enthusiastic, this beautiful divine thought is really right for the sullen taste.

There are two peach blossoms on the chest, which are neither big nor small, about a copper coin, and the size is a bean. Bai Shimo, who doesn't know where to reincarnate, will definitely not be like Lao Zhang, who figured out "lightly and slowly twisting and wiping and re-picking" at this moment.

Again, what other families use is a technique, the Zhang family is playing a sword, and even the most pungent Ashde Yinchu also popped out a "flesh tongue with flowers" praise here.

A girl made of water, a man who is also like charcoal, yin and yang, just gasping with a coquettish sound, it is a wonderful thing.

This is also a woman who is full of joy and joy, delicate and elegant, and there are more than 10,000 kinds of styles. But no matter how fairy you look, the fairy body, in front of this reckless body, it is probably not very poetic.

"Ah Lang...... Aaron loves me! ”

"To love you, to love you, is to love you!"

Push the waist and abdomen, lift the legs and rest the shoulders, that posture, like a foolish man who bears the mountain, and like an old man who drives a cart. Seeing that the muscles were tense, and the indescribable killing decision, the girl Chenghuan opened her mouth, and between a little red lips, the brushed crystal liquid was more charming than the viscous stretching of sugar water.

Squeak squeak, squeak......

The desk of pear blossom wood trembled slightly, and the study was suddenly swept quiet, perhaps it was the dance and ink here after all, so I listened to the rough man who pressed on the white silk girl and said: "If the two love for a long time, they will only look at the light insertion and ......slow delivery."

"Phew!"
