I don't know which t value you mean. If it is Unicom's business, T is the initial letter of the text, which is the pricing unit of the text content.
If it is medical, T value refers to testosterone, which is also an important index for examining testicles.
The normal value of testosterone is between 1.7-7.8 1. If the t value changes greatly, it is likely that some diseases have occurred in the body. The most common is male orchitis.
