1. There is no need to add APP_SECRET after the ordered parameter string.
(Note: Note the second reason. Without sign_method, some people say that without this argument, there is no need to add secret at the end. I didn't verify it. In case you must add sign_method, you can try adding secret at the end.
2. The 2.API says that sign_method is a system parameter and is necessary. Actually, it can be omitted. Default md5
3. Add one more parameter, partner_id. If it is missing, it means that the signature is wrong.
partner_id=-apitools
4. A session is not necessary. The description of API system parameters is unclear. This parameter is necessary for some APIs. In a sandbox environment, if you don't add a session, he will prompt you for an error.
Correct calling method:
Using the sandbox test, it will give the correct patchwork URL, and you can prepare parameters according to it, so you can call it normally.
How to correctly calculate the independent variable WebRtc AECM of WebRtc-AECM-msInSndCardBuf on Android (Samsung GT-I9 100G) and get the echo cancellation "almost", but it is difficult to calculate the programming of the value "msInSndCardBuf". What we have done here before: processing real-time audio with AudioRecord and AudioTrack, and echo appeared. Wrap WebRtcAecm function in JNI. Use the WebRtcAecm JNI interface to process this echo. We use a constant value from 240 milliseconds to "msInSndCardBuf", but if the delay changes for any reason (thread, etc.). ), AECM is poor or even poor. Therefore, we hope to be able to calculate the "msInSndCardBuf" programming constant in 240 milliseconds). I think it's in the audio_procession.h algorithm:
Delay = (t _ render-t _ * * yze)+(t _ process-t _ capture)
The sign signature generated by Taobao api is incorrect, and the signature of calling Taobao API has been incorrect for the following reasons: 1. There is no need to add APP_SECRET after the ordered parameter string (note: note the second reason. Without sign_method, some people say that without this argument, there is no need to add secret at the end. I didn't verify it. In case you must add sign_method, you can try adding sum at the end.
How to correctly set the argument is usually 20 balanced moving averages, and the upper and lower lines are upper and lower lines respectively. First calculate the standard deviation SD of the closing price in the past 20 days, and then multiply it by 2 to get 2 times the standard deviation. The upward line is 20 average plus 2 standard deviations, and the downward line is 20 average minus 2 standard deviations.
The argument you gave is wrong, isn't it?
1, indoor screen is generally not p20, generally 5.0 and 3.75.
2. The unit board size is 600*240MM long, and there is no such specification ~
The width and height parameters are the values of physical points on the screen. Specific cell board:
5.0 board, 64 minutes long, 488mm, 32 minutes high, 244 mm
3.75 plate, 64 minutes long, 304mm, 32 minutes high,152 mm.
Specifically, you can measure the size of a unit board to see what kind of board it is, and then calculate the total number of points.
If not, you can only count them one by one ~ ~ haha
Another method is to gradually adjust the length and height values in VisionShow until they are normal.

How to calculate Gini coefficient correctly? Assuming that a country has 100 people, calculating the Gini coefficient of this country is divided into the following four steps: 1. Rank these 100 people from low to high in income, with the first being the lowest income and the hundredth being the highest income; 2. Draw a square with a long side and connect the diagonal lines of the lower left corner and the upper right corner; 3. Calculate the income ratio of the top ten, top twenty and top thirty ... until the top ninety accounts for the income of the whole 100 people; 4. Take the lower left corner of the square as the origin, mark the cumulative population with horizontal edges, mark the cumulative income ratio with vertical edges, and mark the cumulative income ratio calculated above in the square. Then, connect these points with the origin and the upper right corner of the square to get a curve. This curve is called Lorenz Kruff curve. Gini coefficient is the ratio of the area between diagonal and Lawrence curve to the area of triangle below diagonal. If the income is evenly distributed, the Lawrence curve coincides with the diagonal and the Gini coefficient is zero. If the income is extremely unbalanced, such as the income of the top 99 people is zero, the Lawrence curve coincides with the right line of the square, and the Gini coefficient is 1.
How to set the mode in OTDR test parameter setting correctly If it is automatic, the test distance and pulse width cannot be set, and can only be adjusted in manual mode. Generally, the testing distance is 1.5 to 2 times of the tested optical fiber. If you don't know the approximate length of the optical fiber, test it automatically first.
How to correctly search what you want to buy in Taobao first, then shop around (which can be sorted by reputation), see the credit evaluation and comment records of goods (which is very important), and finally weigh it again and again, think it's ok, just do it, buy more times and have experience, and wish you good luck.
How to correctly calculate the profit of drugs;
The sales price of drugs minus the purchase price of drugs is gross profit.
Subtract the employee's salary, rent, utilities and some expenses, which is the profit.
Finally, the income tax is paid, and the rest is the final profit.
