TF refers to the total time difference, also called "total free time". In network planning, the time difference of an activity indicates how much mobile time (ample time) can be used for the activity, which is equal to the difference between the earliest start time and the latest start time of each process.
In other words, how long can the start time of this activity be delayed without affecting the completion period of the whole project? This time difference is called activity time difference. Obviously, the greater the time difference, the greater the potential of available time.
2. Transfer function
Transfer function. One of the functions of computer accessing the network. The computer access network mainly has five functions, namely account function (UPF), service port function (SPF), core function (CF), transmission function (TF) and management function (AN-SMF).
3. Gravity unit
TF is ton force, which is the main unit of force in the engineering unit system, meaning 1 ton force. Ton force is the gravity of 1000kg matter on the earth, which is exactly equal to 9.8* 1000 Newton, 1 ton force (tf)=9.8* 1000 Newton (n).
4. Domain name
Tf is the domain name of France's southern hemisphere territory, belonging to overseas domain names. The domain name tf of France's southern hemisphere territory belongs to overseas domain names. There is no restriction on the qualification for registration. Tf domain names can be registered by individuals or enterprises in any country.
5. Task Force
The Special Task Force (STF) was established in mid-2006 at 5438+0. It used to be a temporary task force under the Customs Intelligence and Investigation Department, whose main responsibility was to eliminate piracy, illicit cigarettes and illegal fuel sales.
In addition, the information collected during the operation will be forwarded to the Intellectual Property Investigation Bureau for follow-up, so as to ensure that the illegal activities of importing, manufacturing, distributing and storing pirated products are analyzed and sorted out, so as to facilitate the planning of larger-scale sweeping operations in the future.
