transference of imagery: a comparative formalistic study of shakespeares hamlet and its two persian translations
هدف از این تحقیق بررسی انتقال صور خیال هملت در دو ترجمه ی فارسی آن از نظر فرمالیستی بود. برای بدست آوردن داده-های مورد نیاز، 130 نمونه استعاره، مجاز، ایهام، کنایه و پارادوکس در متن اصلی مشخص شده و سپس بر اساس مدل نیومارک (1998) برای ترجمه ی استعاره یا بطور کلی زبان مجاز با معادل های فارسی شان مقایسه گردیدند. این تحقیق بر آن بود تا روش های استفاده شده برای ترجمه هر کدام از انواع زبان مجاز ذکر شد...
15 صفحه اولRequirements for the Transfer of Lead-free Piezoceramics into Application
The recent review for the Restriction of Hazardous Substances Directive (RoHS) by the expert committee, appointed by the European Union, stated that the replacement of PZT “... may be scientifically and technologically practical to a certain degree ...”, although replacement “... is scientifically and technically still impractical in the majority of applications.” Thus, two decades of sustained...
متن کاملTowards Lead-Free Piezoceramics: Facing a Synthesis Challenge
The search for electroceramic materials with enhanced ferro-pyro-piezoelectric properties and revealing the perovskite type structure has been the objective of a significant number of manuscripts reported in the literature. This has been usually carried out by proposing the synthesis and processing of new compounds and solid solution series. In this work, several methods to obtain ferro-pyro-pi...
متن کاملExtrinsic Contribution and Instability Properties in Lead-Based and Lead-Free Piezoceramics
Piezoceramic materials generally exhibit a notable instability of their functional properties when they work under real external conditions. This undesirable effect, known as nonlinear behavior, is mostly associated with the extrinsic contribution to material response. In this article, the role of the ferroelectric domain walls' motion in the nonlinear response in the most workable lead-based a...
متن کاملNonlinear properties of lead zirconate–titanate piezoceramics
Nonlinear properties of lead zirconate-titanate ~PZT! piezoceramics are investigated using ultrasonic second harmonic generation technique. When a sinusoidal ultrasonic wave of frequency v0 is sent into a nonlinear material, the second harmonic wave with frequency 2v0 is generated. Through measuring the absolute amplitude of the fundamental (v0) and of the second harmonic (2v0) waves, the ultra...
