Explain what is a self solution file?

You understand the compression first, first open the compressed file with winrar, and then see what files are inside, as long as you can see the files, then the description of this compressed file, in fact, is only the document. If you see other files, you have a problem with the extraction method. Extract elements when blended into all selected files, or select the top two dots and then click on the unzip time.

Also, if you open the antivirus software then but the other file in the compressed file is a virus, it can be unzipped after the file is deleted by the antivirus software.

The following installation package will be automatically installed and opened with its own recognition.

Once WinRar is installed, right-click on the file you want to unzip and unzip it to a folder.

Not all stand-alone games have to be decompressed, or disc images, you need to use a virtual optical drive.

Some of the software programs built into the system and the applications you install will create their own folders on your phone's memory card by default, and Tencent is created by QQ. The pea pod is created by wuandoujia, and so on. Some folders are the English name of the software, and some are in Hanyu Pinyin.

It looks complicated, but it's actually quite simple to analyze it carefully. The folders in the root directory are created by the system when the system is installed, such as:

Folders in mobile phones can be divided into two categories: system folders and application folders.

Different mobile phones, folder naming results are also different, and there is no need to explain the annotation of Chinese characters.

Common English are:

Android -- Android.

apks - Android) app installation package.

officel -- document office processing.

1. Erection of base stations:

Choose a place with a wide field of view and high terrain to set up the base station, and there should be no high-rise buildings or dense forests (poor satellite reception), large ponds (serious multipath effect), high-voltage transmission lines or transformers (interference) near the base station. The base station is generally erected at an unknown point, and the following instructions are all applicable to this situation. (In this case, the base station does not need to be aligned).

2. New projects:

Open the Hi-RTK road software, go to "Project", select Unnamed, "Apply", enter the project name and confirm, (the purpose of selecting "Apply" instead of "New" is to make the created project do not contain any human parameters).

Then: Project Info --- Coordinate System --- Change the coordinate system name to "China - 'Project Name'" and confirm whether the original parameters of each option are correct, please correct the changes that need to be changed ---Save --- exit ---pop up "Update Point Library") Yes.

5. Collect known points and obtain parameters:

1.Collect known points: It is recommended to use "Smooth Acquisition" when collecting known points, and the button is the penultimate button of the toolbar. (A minimum of two known points is collected, and at least three known points are required for the calculation of seven parameters).

2.Enter the theoretical coordinates of known points to the point library: Broken step measurement--- control point library --- added (the first button in the toolbar) - confirm after entering the point name, x, y, h).

3.Parameter calculations:

Main interface) Parameter ---Coordinate system--- parameter calculation--- select the calculation type, and use 'four-parameter + elevation fitting' when collecting two known points)-Add ---Source Point' as the point collected in the field, 'Target' as the input known point, and Button as the call point library information. ) - Save ---Continue Adding) - Solve --- using the --- coordinate system) Save ---whether it is overwritten or not) Determine --- OK ---Update Point Library) is --- exit. (Please make sure that the pairing is correct).

4.Perform split-step collection or stakeout.
