It is advisable not to act rashly until everything is stable.

At present, China's housing prices are at a high level, and the trend is still unclear. But I estimate that around 2010, there must have been a process of downward adjustment or relative downward adjustment of the house**.

When China's **bubble bursts, that is, when the property market **.

Second, as you said, mortgage interest rates are high right now, but they're going to keep rising. Remember my sentence: "Within 2 years, the commercial housing loan with a term of more than 5 years will definitely rise to more than 12".

On the one hand, the range of wages is limited, and on the other hand, prices and inflation continue to rise, so at this time, if you buy a house in debt, the quality of life must be seriously reduced.

The essence of life is to enjoy it, and not to let yourself be burdened by the social economy too early.

You're a girl, you're still young. There are still a lot of variables that should not be tied down by the house.

It is recommended to buy, the house is real estate, it will not be lost, if you stay in Chongqing in the future, you can live by yourself, not in Chongqing, just sell it.

In fact, it's useless for you to buy the house, you always have to get married, leave this matter to your husband, what do you care?

There is no specific thing to talk about with your girlfriend, you need to find a breakthrough point to arouse her to speak, and then find something from her words to tease, and then have nothing to tell about the interesting things you had when you were a child, the interesting things you saw, the interesting things that just happened today, you usually pay attention to observing more things and you don't have to worry about nothing to talk about, you can also see what your girlfriend likes, you also know a little more, so that you can increase the common language, and talk more, and jokes, find a few classics, pay attention to the skills of telling jokes and throwing baggage... In short, it's good to chat more!!

Error Description:

1.The shaft extension step should not be flush with the bearing cover or inside the bearing cover (you don't want to let something on the shaft extension rub against the non-rotating parts).

2.The fitting size with the inner and outer rings of the bearing should not be too narrow and too thickIt seems that the shaft diameter of the bearing is larger than the shaft diameter of the limit ring?

4.Here a shoulder is designed on the shaft to prevent axial slip 5The bearing is no longer in the housing.

6.Here an interference fit ring is designed to prevent the gear from moving in series in the axial direction7Pay attention to the direction of the angular contact bearing, and when the axial load is large, it is best to use the back-to-back installation method.

I usually don't work hard, and I crammed for exams.

1 The derivative of f(x) f'(x) = a+1 x

When f'(x)" 0, fx increases monotonically, and it can be solved that the monotonically increasing interval of x is the supplement of the increasing interval of the single-decreasing interval and calculates it by yourself.

The solution set of the monotonically increasing interval is the same as (ax+1)x》0, and x is not equal to 0, and the landlord can find the solution set by assuming the positive and negative of a,].

2. 2m*x+2m*lnx=x 2 can be written as 2m*lnx=x 2-2mx

Let gx=2m*lnx kx=x 2-2mx (let them be the left and right parts of the equation respectively), draw the image of gx and kx, and find the geometric meaning of the problem, that is, there is only one common point (no common point can be considered an empty set of solutions).

When m<0 draws the image of gx and kx (gx is monotonically decreasing, kx axis of symmetry is to the left of y, past the origin), there is only one intersection point, which is in line with the title.

When m>0, the drawing (gx is monotonically increasing, kx is on the right side of the y-axis, and crosses the origin) is uncertain and needs to be calculated.

Since it is a quadratic function image and a logarithmic function calculation, it is too difficult to calculate directly. The idea must be placed on only one intersection point, at this time the intersection point is tangent (do it yourself, don't draw it is not able to understand what I say, and the origin of the geometric meaning must be clear), the slope of the two images in the intersection part is the same, that is, use the derivative of gx and the derivative of kx to list the equation, if you will find the derivative, I will directly write the equation 2m x=2x-2m, get x 2-mx-m=0, and.

Let the tangent point (b,c), i.e. b 2-mb-m=0(1).

At this point, x is also satisfied.

c=2mlnb (3)

c=b^2-2mb .(2)

From (1), (2), (3), b=1, m=1 2

Is this math, is it to be solved with a computer program?
