What does it mean to read the next digit of the graduation value

Meaning: Estimate one, say your ruler, the smallestGraduation valueIt's 1 millimeter, and the next digit of the reading value is to read the millimeter.

Graduation value: that is, the minimum scale value, which is the minimum value that can be read in the measuring instrument, refers to the value of the minimum grid between two adjacent scales on the measuring tool.

Counterpoint

In this method, each digit of the measured value is given in units with its length according to the unit it bears.

One-to-one correspondence. In this problem, the unit digit "0" corresponding to m corresponds to m, "1" corresponds to the unit of dm, "7" corresponds to the unit of cm, "5" corresponds to the unit of mm, and "3" corresponds to the unit of mm. In physical experiments, the measurement length should be estimated to the next digit of the graduation value, and the "3" in the question is estimated, then the "5" corresponds to the accurate reading on the graduation value, that is, the graduation value is mm.

If the unit of a ruler is cm, generally its graduation value is the range that can be accurately measured. The next digit of the reading scale value is estimated. For example, the thickness of a book you measure with a ruler in between.

If the line is biased towards the thickness of time, it can be estimated to be something like that.

If the minimum scale (i.e. the graduation value) of the scale you use is centimeters, read it as .

Because 2 corresponds to centimeters, 0 corresponds to millimeters, and the next digit of the graduation value is read to the millimeter, so it is read as cm;

If you use a scale with a minimum scale of millimeters, read it as .

Because 2 corresponds to centimeters, and the first zero on the left corresponds to millimeters, reading the next digit of the graduation value, that is, reading the next digit of the millimeter bit, so it is read as cm.

EstimatedGraduation valueThe next digit of the estimate is the next digit of the minimum scale value that is read.

means that the next digit is 1 10 of the graduation value.

Commonly used measuring instruments, such as the decimal scale, are divided into 10 divisions every 1cm, and each index value is 1mm; Micrometer.

The movable scale section is marked with a number for every ten scales, and each minor division is.

Displacement method. In this method, the decimal point is moved between the last digit and the penultimate digit of the measured value, and the unit of the measured value is the graduation value of the scale used to measure the value without changing the size of the measured value.

In this problem, move the decimal point between "5" and "3", and the unit of the size without changing the original value should be mm, that is, mm, and the graduation value of the scale used to measure the ratio is mm. For example, if the measured value is 40 mm and the displacement is cm, the graduation value of the scale used to measure the value is cm.

The next digit of the index value is estimated to refer to the minimum scale unit of the measuring instrument you use, for example, the minimum scale of the plastic ruler we commonly use is mm, you measure the length of an object, but you have to see if the measurement is exactly on that scale line, if so, you have to read it.

If it's a little bit more, you need to estimate the corresponding length, like that. It doesn't matter what unit you want to represent, for example, after changing to mm, it is changed to m, which means that the number of digits to be estimated is only related to the measurement tool you use. (Note: Vernier calipers cannot be estimated).

The conversion formula is 1cm=10mm=

If the scale has a graduation value of 1mm, the next digit is.

If the graduation value is 1cm, the next digit is.

Generally, numbers are expressed in decimal decimal, and the next digit is 1 10 of the graduation value

If the scale has a graduation value of 1mm, the next digit is.

If the graduation value is 1cm, the next digit is.

Generally, numbers are expressed in decimal decimal, and the next digit is 1 10 of the graduation value

The index value of a ruler is, as a result, you use it to measure the length of an object is 15m, you have to read it to indicate that the number is not estimated or rounded, if it is, it can only be read as 15m, and it is not allowed to be followed by zero) But the length ratio of this object, and the ratio is small, can not be expressed on the scale of the ruler, at this time, according to your intuition, estimate the number that is about the same, such as, yes, the index value is accurate, is it the next digit?

Graduation value scale value.

The next one is palliative.

The pointer is between two scales, such as 3 and 4.

That's what the reading is.

Whichever one is chosen. Can't simply say yes.

3 or 4

As can be seen from the title, the length of the object is, and the index value is.

Therefore, choose B

It should be filled in, preferably so.

First of all, it must be made clear that there must be an estimate or inaccuracy bit for measurement and calculation based on the measurement results.

When we read the following 0 is the estimated reading bit, which is inaccurate, divided by 400 and the result of the first 5 is also inaccurate, (it can be assumed that someone else reads the result as, divided by 400 after the result is, of which 6 is due to the different estimation results of my pick-up, but the 4 in the accurate bit knows Qi Zhi, and will not change due to the estimation of the reading in the reading) So obviously can not fill in other results, it is even more ridiculous!

1) The scale of 1cm is divided into 10 small scales, so the small scale value of the most small bending pin is 1mm;

2) The corresponding scale value of the left end of the object is the corresponding scale value of the right end of the object, and the length of the object is.

So the answer is: 1mm;
