Excuse me, the ground is uneven, how to determine the standard line, using horizontal measuring instruments? So how does the master make the height?

1. Use the level meter to determine the horizontal plane, then determine the height points on the wall, and connect several height points together to form the horizontal plane. The level meter is used to measure the tilt angle relative to the horizontal position, the flatness and straightness of the machine tool guideway, the horizontal and vertical position of the equipment installation, and so on.

2. Nail a stake in the ground, make a point on it and then set up the instrument.

3, how to locate the ceramic tile to open the corner step we design a standard height around the wall to be pasted, and detect a horizontal line with cotton thread. Before laying the tile, the flatness of the base surface is not guaranteed, in order to achieve good results, generally, the flatness will be adjusted according to the paving.

4. Use a horizontal measuring tool (such as a level) to place it on the ground to determine the horizontal baseline. Move the measuring tool to the top of the column and make sure it is parallel to the top, and record the measurement results.

5. The national standard testing method of ceramic tile flatness is as follows: preparation tools: flat plate, ruler, measuring instrument and so on. Preparation before testing: before testing the flatness of ceramic tiles, the floor needs to be cleaned to ensure that there is no sundries and dust.

6. Make a number of points on the ground where cement leveling is needed, all of which are parallel to the horizontal line of the wall. In this way, there is no difference in the height of the cement floor. Cement, coarse sand, melon seed slices should have a certain proportion, stir evenly.

How to judge the relative sliding trend of the connecting body doing uniform circular motion on the horizontal plane, and how to see the A..

1. Do not say that because of circumferential motion, the friction force points to the center of the circle, and the relative motion trend points to the opposite direction, please use the definition of relative motion trend to judge the direction.

2. Because of the balance, it is impossible for the two balls to be on one side. If they are on the same side, the elasticity mentioned above will inevitably cause the two balls to tend to the wallboard on the A side. Under the above analysis, the two balls must be on both sides of the center of the circle. Because it's connected as a whole and rotates around the center of the circle, so the angular velocity is the same, B pair.

3. The relatively stationary object on the disk is also moving in a uniform circle with the disk, which requires a centripetal force and points to the center of the orbit.

4. Because the whole component rotates around the O point, any point on the component (including point A) moves in a uniform circle relative to the O point. When you connect the AO, you find that it is vertical, and the linear velocity is perpendicular to the radius, of course, horizontally to the left.

5. When an object has a trend of relative motion, it is still at rest, so how to determine the trend and direction of motion? One of the methods is "hypothetical method".

How to draw a plan with a computer?

Find the drawing in the Windows attachment of the system and open it. Create a new file after opening it. After entering the menu bar, we first click on the 2D shape, draw a plan, and there is a 2D shape selection on the right.

First of all, we click on the lower right corner of the desktop, the start icon to open the start menu, and click "draw" Mini Program menu in the interface that appears. There are tools in the drawing tool that can be used to draw a plan. We can use the tool to draw all kinds of plane graphics.

The computer drawing method is as follows: first, we open the computer, click, start-- program-- attachment-- draw, and a drawing layout will pop up. The whole drawing tool can be divided into three areas, title bar, toolbar, paint version, mouse click tool, each tool will show the corresponding function.

First of all, we draw the overall structure of the bedroom. Draw the home figure in the bedroom on the overall structure diagram. Draw a picture of the bed and nightstand in the second bedroom. Finally, draw the floor tiles for the bedroom decoration, so that our interior graphics will be drawn.

How to draw the layout plan drawing method: the first step: you can open the billion map icon (PS: you can also log in directly to the official website to draw online) the second step: create a new plan. Select "Chart"-"Plan", select a template, select a plan template.

By downloading the CAD software on your computer, you can easily draw a basic floor plan. The following are the contents and steps of drawing a plan.

Interpretation of horizontal plane

1. The word interpretation of horizontal plane is the plane formed by completely still water. It also refers to a face parallel to this plane. The term horizontal plane is defined as the plane formed by completely still water. It also refers to a face parallel to this plane. The structure is: water (single body structure) flat (single body structure) surface (single body structure). Part of speech is: noun.

2. Horizontal plane, the projection plane seen from above. The horizontal projection plane is called "horizontal projection plane", that is, H plane; the vertical projection plane perpendicular to the horizontal position and in the positive position is called "upright projection plane", that is, V plane; and the lateral projection plane perpendicular to the above two projection planes is called "lateral projection plane", that is, W plane.

3. It refers to the collection of all points perpendicular to the direction of gravity, that is, horizontally, at the same altitude. In geography, the water level usually refers to the sea level, that is, the average sea level.

4. The interpretation of the horizontal plane the plane formed by completely still water. It also refers to a face parallel to this plane. The explanation of decomposing water is a colorless, odorless, transparent liquid: Rice. Constant dripping wears away a stone. It's packed. River: Han River. Xiangshui. A general name for rivers, lakes and seas. The reservoir. Water conservancy.

5. Horizontal Pinyin: shui ping mian horizontal plane explanation: the plane formed by completely still water. It also refers to a face parallel to this plane. Horizontal plane sentence: it will move toward the horizontal plane. Scientists say its water level drops by more than three feet a year.
