Abstract AR
باستخدام تقريب كرونشين و عدد من معادلات الحالة تم إجراء دراسة نظريـة لتغيـر ترددات اهتزاز شبيكة الألمنيوم و تغير كثافة الأنماط مع الضغط من خلال تحليل طيف التردد الفونوني للألمنيوم.
إن التغير بالحجم النوعي للبلورة يؤدي لتغير ترددات اهتزاز الـشبيكة مـن خـلال إجراءات معقدة.
يعرض هذا البحث إمكانية التغلب على هذه الـصعوبات باسـتخدام تقريـب كرونشين و معادلات الحالة لمرنكهان، برخ-مرنكهان و معادلة فينت•
Abstract EN
A theoretical study was made of the pressure dependence of lattice frequencies and distribution function for aluminum by analyzing phonon frequency spectrum, using Grüneisen approximation and many equations of state (EOS).
Each change in the specific volume of a crystal excites a change in the frequencies of lattice vibration in a very complex manner .
This work shows how this complexity can be overcome at least approximately depending on Grüneisen approximation and Murnaghan , Birch- Murnaghan and Vinet equations of state.
