Hurry, hurry! Ask for help below, reproduction, etc!! There is a bounty!

Boss, you still give your pet to someone else to keep for a while, and then you really don't want to go to the hospital to prepare a new towel at home, a new basin, boil water every day, and the water temperature is 65-70 degrees as well. Wash three times a day, avoid eating, don't eat green onions, ginger, garlic, tofu, especially stinky tofu, don't eat spicy, don't eat beef and mutton, don't eat fishy cold food, the most important thing is not to catch, I guess you can't do it, then cut your nails, wash your hands with soap before you want to catch it every day, so for two weeks, it is estimated that you will become a fairy.

It seems to be a rash, and it seems to be an allergy, it is recommended to go to the hospital to find a specialist, or to buy some **** allergy drugs, depending on where you live, there should be a big hospital nearby.

It may be that a **disease in the pet has infected you, it is recommended that you do not catch it, and go to the hospital as soon as possible**.

The symptoms are not clear, it may be measles, it may just be allergies, or it may even be transmitted from animals, and I can't be sure of it, and I can't be accurate**.

In order to ensure that you can see a doctor as soon as possible**, it is recommended to see a doctor as soon as possible

My husband's symptoms are the same as yours. The doctor said it was allergies, took a drip, and also took the damp poison clear and snow beauty anti-beauty liquid. Today, the red film went down, but there are still red dots. Let's go to the hospital. It's allergies.

Hurry up and go to the hospital sodium... I think it's allergic.

Hehe seems to be something, sores, I've had it, but I forgot what it was.

I went to the hospital, got the medicine, and it didn't take long for me to get better.

(1) From the title, 2 a+2 1 b-1 = 2(b-1) a+2 (hour), answer: it takes 2(b-1) a+2 to drain the water of the pool;

2) When a=2, b= 3 2, 2(b-1) a+2 = 2( 3 2 -1) 2+2 = 1 4 (hour), answer: when a=2, b= 3 2, it takes 1 4 hours to drain the water in the pool.

Let the total volume be "1".

（a+2）=1/(a+2)

1÷（b-1）=1/(b-1)

1/（a+2）×2÷1/（b-1）

2(b-1)/(a+2)

2. Substitute a=2, b=3 2, 2 1 2 (2+2).

Set x hours to be finished.

a+2:b-1=2:x

x=(b-1)*2/(a+2)

x=(2b-2)/(a+2)

2) Substituting a=2, b=3 2 into the above equation, x=(3-2) (2+2)=1 4

1) Flow rate f=1000kmol h, xf=, xd=, **rate = then there is: **rate = (d xd) (f xf), in the formula except d the amount is known, the solution is d = 400kmol h, w = f-d = 600kmol h by the weight balance of benzene: f xf = d xd + w xw, in the same formula except xw the amount is known, xw = (2) first calculate the minimum reflux jujube spring withering ratio rmin bubble point feed, so q = 1, q line equation is:

x=xf=, substitute the phase equilibrium equation: y= x [1+( 1)x], and obtain y=i.e., xp=, yp=, and obtain: rmin=(xd-yp) (yp-xp)=, so r= obtains the operation line equation of the distillation section as:

y=rx (r+1) +xd (r+1)= + 3) bubble point reflux, so the top of the column (the first plate) is composed of, xd=, substituting the phase equilibrium equation: yd= the liquid phase composition of the second plate x2 can be calculated from the operation line of the distillation section: yd= + x2 = continue to use the phase equilibrium equation to calculate:

y2= The second question is a bit wrong, the substitution of the data is wrong, the third question should use x=y [1)y] to calculate the liquid phase on the plate, and recalculate: (2)y=rx (r+1) +xd (r+1)= + bubble point reflux, so the top of the tower (the old plate of Disen) is composed of, y1=xd=, and the stool is hollowed into x=y [1)y] to obtain the liquid phase composition of x1=the second plate x2 can be calculated by the operation line of the distillation section: y2= + to obtain y2=

Input method: right-click the task bar--toolbar--language bar (check the table key and show the silver, and go to the check to indicate that it is not displayed).

Volume adjustment: Banquet control panel - sound and audio equipment - volume selection card - put the volume chart into the taskbar (check it to show it, and uncheck it to show it).
