翻译:However, in our country there are still no installations for conducting such tests. It should be noted that the low venting of the detector causes the gain of the processing path to increase to ensure operability, while also increasing noise levels caused by reflection from walls and from external light sources. Thus, the detector became a constant source of false alarms. However, to undergo certification, it is possible to achieve the required sensitivity of the announcer to cotton decay (0.05 - 0.2 dB/m) and at an insufficient ventiliruyemost of a smoke chamber. But, as you know, cotton in our country is not the main fire load. And the sensitivity to the rest of the smoke remains unknown. Therefore, one cannot be sure of the ability of smoke lime bodies to detect real fires. But it is worth noting that abroad the appearance of a new smoke chamber does not occur annually and is an event.

然而,在我们国家仍然没有进行这种测试的设备。值得注意的是,探测器的低通气性会导致处理路径的增益增加,以确保其可操作性,同时也会增加由墙壁和外部光源反射引起的噪音水平。因此,探测器成为了虚警的常见来源。然而,为了获得认证,可以在烟气室通风不足的情况下实现对棉花腐烂的报警器所需的灵敏度(0.05-0.2 dB/m)。但是,正如你所知,在我们国家,棉花不是主要的火灾负荷。对其它烟雾的灵敏度仍然未知。因此,不能确定烟灰体探测真实火灾的能力。但值得注意的是,在国外,新的烟气室的出现并不是每年都会发生,是一件大事。

ERROR: Could not find a version that satisfies the requirement Cython (from versions: none) ERROR: No matching distribution found for Cython
Cython is a programming language that is used to write Python extension modules. It allows you to write Python code that can be compiled into highly efficient C or C++ code, which can then be used as an extension for your Python programs.
To resolve the error you encountered, which indicates that a compatible version of Cython could not be found, you can try the following steps:
1. Make sure you have the latest version of pip installed. You can upgrade it by running the following command:
```
pip install --upgrade pip
```
2. If you are using a virtual environment, activate it. This step is optional but recommended to isolate package installations.
3. Try installing Cython again with the following command:
```
pip install Cython
```
If these steps still don't resolve the issue, there might be some compatibility problems with your system or Python version. In that case, please provide more information about your system setup and Python version so that I can assist you further.
These critical programs are missing or too old: gawk bison *** Check the INSTALL file for required versions.
This error message indicates that the gawk and bison programs are either missing or outdated on your system. These programs are required for some software installations and builds.
You can try installing/updating them using your system's package manager. For example, on Ubuntu, you can run the following command in the terminal:
```
sudo apt-get install gawk bison
```
If you are using a different operating system, you may need to use a different command to install/update these programs.
If you are still facing issues, you can check the INSTALL file of the software you are trying to install for the required versions of gawk and bison. Then, you can manually install the required versions of these programs on your system.
