في هذا البحث، قمنا باشتقاق معادلة تحليلية تعطي تابعية ضغط الغاز الكلي لزمن
الاستخدام من أجل أنابيب عدادات GM المخمدة-ذاتياً بالهلوجين و من أجل أنابيب
عدادات GM المخمدة-ذاتياً ببخار أو غاز عضوي. تدل هذه المعادلة أن ضغط الغاز،
في الأولى، يتناقص أسياً مع الاستخدام عند ثبات درجة حرارة الأنبوبة و ثبات النشاط
الذي تتعرض له.
In this research, we have derived an analytical equation gives
dependency of the total gas pressure to operation time for halogen
self-quenched GM counter tubes and organic vapor or gas selfquenched
GM counter tubes. This equation indicates that the gas
pressure exponentially decreases as the operation time increases, at
constant temperature of tube and constant activity that this tube
exposed to.

In this research, we derived a non–paralyzable dead time
equation shows the relation between the dead time and those factors.
This equation shows the dead time as function of the applied
voltage, pressure, temperature, dimensions of counter tube and type
of the gas.

In supervised learning, a well-trained model should be able to recover ground truth accurately, i.e. the predicted labels are expected to resemble the ground truth labels as much as possible. Inspired by this, we formulate a difficulty criterion base
Corrosion is the most important problem in the process of oil production, Its results are: sudden fracture, high economic cost and great loss in oil equipment. Appropriate solutions have been suggested to extend the life of facilities, and to avoid c
