The younger brother has some detection issues 20

Please contact the inspection and quarantine department.

Moisture: Karl Fischer method for measuring trace water.

Ash: weightlessness method.

Acidity: If a large amount of liquid can be used with a pH meter, other matrices require a different method.

Carbohydrates: Generally speaking, it is not possible to easily determine the type and content of sugar of unknown kinds, and the total carbohydrate is generally expressed in terms of glucose. Colorimetric methods can be used.

Vitamins: liquid chromatography, basically each has its own method of determination.

Dimensional element: atomic absorption.

Protein and amino acids: Kai nitrogen determination method.

Ahem, look at the clarity of the screen, and whether the logo behind it is brighter.

Hello, please analyze and solve it from the following aspects.

1 Computer poisoning or malware may also cause computer abnormalities, the solution is to upgrade the anti-virus software, anti-virus, if it really doesn't work, reinstall or restore the system. Reinstalling or restoring the system can completely resolve the software side of the problem.

2. Unreasonable configuration, uncoordinated, and incorrect BIOS settings will also cause computer abnormalities, so you should find more professional personnel to solve the problem when installing or upgrading hardware. You can send the configuration down to help you see if the configuration is reasonable.

3 The high temperature of the computer will also cause the computer to be abnormal, it is recommended to use Master Lu software to measure the temperature of the hardware, and then solve it.

4. Due to the voltage instability point, the power supply is not enough, and it will often cause computer abnormalities, if it is caused by these reasons, configure a voltage regulator, and replace the high-power power supply to solve the problem.

5 Caused by running large software and programs, such as playing big games, using large software, watching Blu-ray movies, etc., it should be caused by poor computer hardware configuration. The only solution is to upgrade the computer configuration and optimize the computer system.

6 Old computer Because there is too much dust in the case, it is easy to cause computer abnormalities caused by short circuits. Clean the inside of the chassis frequently.

7 Old computer Due to the long period of use, the capacitance of the motherboard circuit is aging, which will also cause abnormal problems in the computer. Only sent for repair or replacement.

8 Old computer hard disk will also fail after a long time, causing the computer to crash, which requires the use of hard disk testing software to test the hard disk, repartitioning the installation system can repair the hard disk logical bad sectors, can not be repaired, and only to replace the hard disk.

If it helps, please choose the answer you are satisfied with!!

You are win7 system, I can see it,As for the crash, the computer fan is not forceful, resulting in ** processing (CPU) temperature is too high and the crash phenomenon is too high,Try it with a fan!

Is there a virus?,Or the memory is not enough.,Or the motherboard is hot.,Can't bear it.,Automatic shutdown.,Change the motherboard.,Also,Play less big games.。

Answer: The landlord said that the "annotation under the beam" 2 25 + 1 22 ", in the flat method is the in-situ annotation, and the in-situ annotation is a supplement to the centralized annotation, that is, the bottom of the beam is long rib. Therefore, the bottom of the long rib is 3, 2 25 + 1 22, arranged as 25 on both sides, and 22 in the middle

Supplement: in the centralized annotation of KL7, 2 25 is the upper long bar, and the lower steel bar is not marked; Therefore, the lower part of the beam is marked with reference to the in-situ position of the beam.

Isn't that indicated, 2 roots 25 lengths, the 2 25 + 1 22 you said is his in-situ marking, not long.

The bottom is all long steel bars. (Is there still a truncated bottom rebar?) ）

If the in-situ annotation under the beam is 2 25 + 1 22, it means that it is all long. You check the annotation description of 03G101-1 with beams.

Hehe, the bottom is all long steel bars? What are the rules there? Hehehe, this is a flat annotation with axillary beams, and the answer is this.

KL7(3)300 700 Y500 250 Beam width 300, height 700, 3 spans, add horizontal length 500 at the bottom of the support, height 250, is added from the bottom of the beam downward, you do not give the axillary reinforcement, you look at the drawing, there should be, if there is no standard, then the minimum reinforcement according to the specification is 2 12.

10@100 200(2) stirrups, 100 in, 200 without 200, 2 hoops, add 2 to 2 times the beam height.

2 25 beam top erection reinforcement.

N4 18 Torsional Waist Tendons.

The elevation of the top surface of the beam is relative to the elevation of the number of layers where the beam is located, that is, the top of the beam is reduced by 100 mm 2 25 + 1 22 is the in-situ annotation of the bottom of the beam.

The easiest way to do this is to use the Light and Shadow Magic Hand to open** and see the NEXF information, and the last item is the number of shutter speeds.

Light and shadow magic hands to view ** information.
