يعد الهواء من الضروريات لعيش الانسان وكلما كان الهواء نقياً كلما كانت صحة الانسان جيدة، وفي الآونة الاخيرة اصبح الهواء يتأثر بالملوثات وهنالك عدة متغيرات تؤثر في نقاوة الهواء واصبح الهواء يؤثر على صحة الانسان لما يحمله من ملوثات توثر على جسم الانسان وصحته. ولمعرفة مدى تلوث الهواء في كل مناطق الارض تم بناء مؤشر لمعرف تلوث الهواء بالاعتماد على عدة متغيرات يسمى بمعامل تأثير الهواء. ولبيان اكثر المتغيرات تأثيرا على هذا المعامل تم بناء انموذج انحدار وبما ان معامل تأثير الهواء غير دقيق فتم استعمال انموذج انحدار ضبابي معلمات والمتغير المعتمد ام المتغيرات التوضيحية فكانت جازمة. وفي بحثنا هذا تم بناء انموذج انحدار ضبابي لتلوث الهواء العراق، وتم تقدير معلمات الانموذج للوصول الى العوامل التي لها تأثير اكبر في تلوث الهواء في العراق بعد ان تم جمع البيانات من وزارة البيئة العراقية عن معامل تأثير جودة الهواء (AQI) والذي يعتبر معيارا اساسيا لقياس تلوث الهواء وهل هو جيد او مقبول او سيئ للأشخاص الحساسين ام خطير من خلال ستة عوامل تمثل المتغيرات التوضيحية هي (co2,o3,so2,pm10.pm2.5,NO2) والتي بياناتها غير ضبابية. تم قياسها في الجو عن طريق استخدام محطات تقوم بقياسها منتشرة في المحافظات كافة وتم اخذ البيانات لشهر كامل عن طريق اخذ ثلاث قراءات في اليوم الواحد ولجميع المحافظات كل 8 ساعات وتم اختبار البيانات للتأكد من مشكلة التعدد الخطي وتبين وجود المشكلة وتم استخدام انحدار الحرف الضبابي لتقدير معلمات الانموذج وتبين ان انموذج انحدار الحرف الضبابي يعطي تقديرات افضل دقة. ومن خلال المقارنة مع جدول المعايير نجد ان كل محافظات العراق خارج نطاق المديات التي لا تؤثر على صحة الانسان.
Academic writing is a key skill for success in academic life, particularly for graduate students of a foreign language. The importance of writing to academic culture, practice, and knowledge building has led to a great deal of research in many fields, including rhetoric and composition, linguistics, applied linguistics, and English for Academic Purposes (EAP).

Synonyms in the Arabic language are very few, rather rare, and in the Holy Qur’an they are completely non-existent. And how were these words, close in meaning, translated in the translation of the Holy Qur’an by Almir Kuliev into the Russian language.

Comparison is the most common and effective technique for human thinking: the human mind always judges something new based on its comparison with similar things that are already known. Therefore, literary comparisons are always clear and convincing. In our daily lives, we are constantly forced to compare different things in terms of quantity, quality, or other aspects. It is known that comparisons are used in literature in order for speech to be clear and effective, but when these comparisons are used in everyday speech, it is in order to convey the meaning directly and quickly, because many of these expressions used daily are comparisons. In our research, we discussed this comparison as a means of metaphor and expression in Russia
