Robert Frost is an American contemporary poet who is good at stylistic feature of poems, especially in macroscopic organization, rhetorical methods, grammatical metaphor, vocabulary, rhythmic feature, and semantic relations. Generally, sound is related to phonetics and phonology. Patterns of sound can create melodious effect in poetry, and sometimes a single vowel or consonant will make the verse or even the particular poem significant. Sometimes musical or incantatory effects are achieved through devices such as onomatopoeia, alliteration, assonance and rhythm. A stylistic analysis of Robert Frost's famous poem"Stopping by Woods on a Snowy Evening"is given, which mainly focused on its language features. Through the excellent choice of words and organization of sound, Frost makes the simplest pieces into meaningful poems with beautiful melody and brings readers refreshing sense, flatus of life, tranquility and geniality.展开更多

The permittivity, resonant frequency and dielectric loss of the composites have been measured under vertical stress and temperature, and the variety of the material properties under pressure and temperature could also be obtained. The pressure and temperature stability of the composites have been assessed through experiments. The data of these two types of composites indicated that the stability of 1-342 composite with pressure was better than that of 1-3 composite, and two composites have almost the same dielectric stability with temperature. However, 1-3-2 composite showed slower frequency variation than 1-3 composite.展开更多
