因為台灣人只會欺負台灣人
為了生活,錢少還是要做
不然要餓死嗎?
不過請看學校...
你知道國立大學熱門科系
和私立科大熱門科系
程度是天壤之別⋯？
碩士只要看大學是讀哪
馬上就能區分是純血統還是洗學歷
碩士連Excel語法都不會用的都見過
洗出來也是丟人現眼
證照、語言能力、經歷是很現實的東西
簡稱學識、技術、工作經歷
台灣職場一直以來都很看學經歷
尤其在學時的工作經歷更為重要
耕耘多少就收成多少
有些人在學時都在超商加油站打工
不懂得找科系相關工作洗經歷
如果學歷、語言、證照等等又不佳
畢業後暫時當技術員也不為過
至少不要當啃老族
現在企業要的是"即戰力"不是白紙
況且做技術員也沒什麼
我想沒人說要做一輩子
別人私底下進修也不會和你告知
我大學同學中字輩的也當過大樓保全
當時常常被他們的總幹事嘲笑
不到一年的時間就考上高考走人了
誰笑誰還不知道

其實事前知道會用到的話，先上網找個英文使用說明看看，稍微記一下就行了！

====================
1
Familiarize yourself with the anatomy of a micrometer. Some parts are stationary while others are movable.
Ratchet stop
Thimble
Frame
Thimble lock
Spindle
Anvil
Sleeve

2
Clean the anvil and spindle before beginning. Use either a clean sheet of paper or soft cloth, and hold it between the anvil and the spindle. Gently twist and close on the sheet or cloth. Slowly, pull out the sheet or the cloth.[1]
This practice isn't a necessary step for measuring, but keeping the surfaces of the anvil and spindle clean ensures precise measurements.

3
Hold the object in your left hand and place it against the anvil. The anvil is stationary and can withstand more pressure than the spindle. Make sure the object doesn't move or scratch the surface of the anvil.

4
Hold the micrometer with your right hand. The frame will rest gently on your palm.
You can also fasten the frame on a stationary vise; this helps free up both hands for the measuring process.

5
Spin the ratchet counter clockwise. Be sure the 0 on the thimble is lined up with the scale on the sleeve.

6
Twist until the spindle is against the object. Apply enough force. The thimble often clicks. Three clicks is a good stopping point.

7
Set the thimble lock while the micrometer is still on the object. Even though it is on lock, the spindle can still be moved.

8
Slide out the object carefully. Be sure to avoid scratching either surfaces of the anvil or spindle; the slightest scratch can ruin the micrometers measuring accuracy.

Write down the measurements before unlocking the spindle. If the spindle loosens, be sure to remeasure.

Reading an Inch Micrometer
Image titled Use and Read an Outside Micrometer Step 10
1
Learn the different number scales on the thimbles.[2]
On the sleeve is a scale that measures by the one-hundred thousands or 1/10 of an inch; in decimal form it would be .100.
In between those whole numbers are three lines that represent twenty-five thousandths of an inch; in decimal form, it would look like .025.
The thimble has evenly spaced lines that represent one-thousandth of an inch; in decimal form it would be .001.
Above the whole number scale on the sleeve are lines that measure to ten-thousandths of an inch; in decimal form it looks like .0001.

2
Read the whole number on the sleeve first. The last visible number will read as the thousandths. For example, if the last number you can see on the sleeve is 5, then it would read 5 hundred thousandths, or .500. ”

3
Read how many lines come after the whole number. Look at the individual markings exposed next to the 100 thousandths and multiply each marking by .25.. In this case 1 x .025 would be .025.

4
Find the number and corresponding marking on the thimble scale closest to but underneath the measurement line on the stock. If it's closest to 1, then it would be .001.
Image titled Use and Read an Outside Micrometer Step 14
5
Add those three numbers together. In this case it would be .500 + .025 + .001 = .526.
Image titled Use and Read an Outside Micrometer Step 15
6
Flip the micrometer over to read to the 10 thousandths marking. Read that line that lines closest with the sleeve. If, for example, it lines with 1, then the measurement will will read .5261

Reading a Metric Micrometer
Image titled Use and Read an Outside Micrometer Step 16
1
Learn the different number scales on the thimbles.[3]
The line on the sleeve usually has top line showing millimeters, and below that line the marks represent half millimeters.
The marks on the thimble usually go to 50, and each line represents a hundredth of a millimeter or .01 mm.
The horizontal lines above the scale on the sleeve will measure to the thousandth of a millimeter, or .001 mm.
Image titled Use and Read an Outside Micrometer Step 17
2
Read the number of millimeters first. If the last line you saw were a 5, then you would have 5 mm thus far.
Image titled Use and Read an Outside Micrometer Step 18
3
Incorporate all the half millimeters in your measurement. If you have one mark that would be .5 mm.
Don't count a mark that is barely showing; the reading on the thimble might be getting close to 50. [4]
Image titled Use and Read an Outside Micrometer Step 19
4
Find the number of .01 millimeters. If the line on the thimble reads 33, then you'd have .33 mm.
Image titled Use and Read an Outside Micrometer Step 20
5
Add up all three lines. In this example, add 5 + .5 + .33. The measurement is 5.83 mm.
Image titled Use and Read an Outside Micrometer Step 21
6
Add the thousandths. If the thousandths read a 6, then at .006 to the measurement. In this example, it would be 5.836
The main time you should incorporate the thousandths measurement is if the object has less tolerance for the pressure applied by the micrometer.[5]
