Director Peng thought for a while and gave Fei Nali a suggestion: "Since this captain Shou's illness is already in the stage of recuperation, with my experience, it is better for you to buy some fresh and easy-to-preserve dishes and bring them over."

"Those beautifully packaged nutritional products are expensive and useless, but they are just good-looking, and with the knowledge and status of Captain Shou, it is estimated that people are not rare in those nutritional products.

"The fruit is too cold, and it is not suitable for the current captain Shou, only the most practical way to buy vegetables, nutritious and sincere, and it is not easy to be politely rejected by the other party.

"You and Warring are colleagues and best friends, listening to the two of you chatting these days, I can hear that you and your lover have a little friendship with Captain Shou, Warlene takes care of Captain Shou, mainly in terms of buying vegetables and cooking, so you carry the vegetables to visit the patient, it will not seem abrupt, everyone cooks and eats together, it is easier to shorten the distance and enhance the relationship, so you bring the vegetables, it is the most suitable.

"Actually, it's not impossible to bring fruit, Captain Shou is afraid of the cold, he can not eat fruit, and the rest of you can use fruit as a dessert after dinner, or as a snack while chatting, but I think if you bring fruit, it will be a bit of a snake. ”

He had heard of Shou Weiguo and his people, as an old fox of his age, if he wanted to understand someone, he didn't have to make too much effort.

"Why is it important to bring fruit?" Fei Nali was puzzled, "Isn't it normal to visit a patient and bring fruit, if the patient can't eat it himself, he can keep it for guests?"

On the contrary, she felt that it was more difficult to buy vegetables, the vegetables were bought less or cheaper, it seemed shabby, the vegetables were bought too much or expensive, and she herself felt sorry for the money, and no matter how expensive the vegetables were, people did not necessarily know, she couldn't quote the money the same, so she would be more shabby and stingy.

"So, you don't necessarily need my experience," Director Peng laughed, "You young people's affairs, or you young people make their own decisions, my experience and insight are outdated for you young people." ”

The three of them talked, and did not delay their work, and after the bundle was completed, Director Peng entered the computer room again.

Fei Nali couldn't make up her mind: "Sister Wollen, do you think Director Peng's method will work, do you really bring vegetables to see patients?"

Warlene shook her head: "You have to take this idea yourself, anyway, in addition to going to work these days, I am dealing with firewood, rice, oil and salt, and I think Director Peng's method is not impossible." ”

Before the two could discuss a result, they saw Director Peng in the computer room fiddling with the hand control box from the monitor, and both of them felt that something was wrong.

Fei Nali said quickly: "Sister Volin, it can't be that the hand control box is broken, right?"

In the case of adding and reducing water to the water tank, in order to keep the fixed distance between the water on the surface of the water tank and the radiant head of the linear accelerator unchanged, it is necessary to adjust the distance by adjusting the height of the linear accelerator machine tool supporting the water tank, and the machine tool is controlled by the hand control box.

Warlene speculated: "It's also possible that there is a problem with the control circuit board, which caused the hand control box to malfunction, I'll go in and take a look." ”

Whether there is a problem with the control circuit board or a problem with the hand control box, it is easier to repair.

If it's a problem with the control board, just replace the broken parts on the board.

If it is a problem with the hand control box, it is generally the loosening of the dial wheel used to control the direction of mechanical movement, or the phase change of the relay, as long as the changed situation is restored to its original state.

I'm afraid, it's a problem with the transmission line, which is very simple to say, but it's quite troublesome to check, because the distance span is large, there are more things to disassemble and assemble, which is time-consuming and laborious, and it may not be able to be checked.

Hearing Warlene's footsteps, Director Peng hurriedly urged: "Warlene, come and see, is the hand control box broken, why can't this bed be controlled?"

"Good. Warlene agreed, and walked up to Director Peng.

She took the hand control box from Director Peng's hand, pressed the enable switch on the back panel of the hand control box with one hand, and toggled the dial wheel in the control position with the other.

The bed can move normally in the up-down and anteroposterior directions, and the left and right directions are abnormal, either unresponsive or moving in the opposite direction.

Wallen hung the hand control box on the hook at the foot of the bed, unlocked the electric control switch on the side of the bed, and tried to manually control the front, back, left, right and left directions of the bed.

Fortunately, there is no problem with manual control, but after the machine tool is in place, when the electric switch is locked, the position of the machine tool is often vibrated away due to the excessive suction force of the relay associated with the electric switch, and sometimes the distance of deviation is more, at most more than three millimeters, sometimes the distance of deviation is less, at least less than one millimeter, and the number of deviation distance is random.

Warlene proposed: "Director Peng, let's finish measuring the data in today's plan first, and then I will repair the hand control box, so as not to delay the use of tomorrow's machine." ”

"Okay, then it's hard for you, I'll give you one more day off. Director Peng directly accepted Warlene's proposal.

Although the error of the machine tool due to the vibration of the relay suction force is random, compared with the problem that Volin has already encountered and dealt with, Director Peng is much more unfamiliar with the manual operation of the machine tool, and this time is not the time to practice, so the next matter of re-debugging the water tank to the exact position is all handed over to Warlene to operate.

Director Peng is only responsible for standing in front of the water tank, helping to look at the scale on the water tank and judging the position error value.

When manually adjusting the position of the machine tool, as long as the electric switch is unlocked, the left and right directions and the front and rear directions of the machine tool are unlocked at the same time, which means that Worlene not only has to manually control the left and right positions of the machine tool at this time, but also pays attention to the position in the front and rear directions.

Although the suction force of the relay has little influence on the front and rear directions, and the influence is fixed almost every time, it also forms a constraint on her adjustment of the position of the left and right directions.

However, if you directly lock the machine and adjust the relative position by moving the water tank, it is difficult to control the force.

Because there are dozens of pounds of water in the water tank, when the water tank is moved slightly, the water tank cannot be moved with less force, and the water tank moves too much because of the inertia with a large force, and the water tank may rotate, which increases the complexity of the position adjustment of the water tank.

After Director Peng and Warlene tried, they both chose to give up moving the water tank.

It took nearly ten minutes for the exact position of the machine tool to be adjusted, and in the following time, every time I went in and out of the machine room to debug the height of the water tank, Director Peng and Wollene worked together to speed up the test.

Because the up and down movement of the machine tool can only be controlled by the hand control box, in order to avoid his own unskilled and misoperation, Director Peng did not touch the hand control box again, and the hand control box was all operated by Warlene.

At nearly eleven o'clock, after the data test of today's plan was completed, Fei Nali and Director Peng left, and Warlene locked the fence door from the inside and began to enter the computer room to overhaul the machine.
