Abstract AR
تم في هذا البحث الحصول على الصيغ الرياضية للمعاملات أو الثوابت الكونية (معامل هابل H(t) و معامل التباطؤ q(t)) و ذلك بالاعتماد أولا على الزحزحة الحمراء من خلال عامل القياس، R(t) و ثانيا من خلال افتراض معامل القياس، R(t) كدالة للزمن القوي a و a (t)، و كانت الصيغ الرياضية لكل من H(t) و q(t) مطابقة للصيغ الرياضية المعروفة.
Abstract EN
In this work we studied the dependence of the Cosmological parameters (the Hubble H (t) and deceleration q (t) parameters) on the red shift through the scale factor R (t), so we obtained two relations for the parameters.
Assuming the scale factor as a function of time to the power α and q (α), we found other sets for the parameters H (t) and q (t).
The derived relations for H (t) and q (t) coincides with the well-known relations for the parameters.
