Contemporary music in 20th century has been much changed since 1950-the year it made a new epoch in music and has brought forth a great transformation. The maincause is that since before or after 1920, Scho¨nberg, Berg and Webern have formed a new "ism"-Dodecaphony. The Dodecaphony is what is called the classic of contemporary music, and its value is being revaluated. Among those musicians, Webern's music is being made more and more up by many people year after year. Compared with Scho¨nberg and Berg, in its diction webern has expressed more clearly the classical feature the absolute purity, thrifty and strictness. So, in this point, this treaties examines closely Werbern's classical feature from the point of diction and formation.

In the design of superconducting devices, stability in the present is the one of the most important factors. Stability is a mesure of the ability of a conductor or device to spontaneously return to the superconducting state after the passage of a disturbance that had either triggered or driven an excursion into the normal state ; this treatise made a study of one of the stability theories, flux jump stability. As a part of flux jump stabilization this treatise derived the stability parameter making use of superconducting theory and thermodynamics, and created the critical current density Jc on the formula. Consequently, the stability of superconductor was improved with considering the heat transfer effect. And this treatise reached the conclusion that the critical current density is uplifted in inverse proportion to the width of superconductor and the volumetric proportion of superconductor. For instance, Jc= 1.01×108 when a=0.018m, λ=0.3 but Jc=5.50×104 when a=0.019m, λ= 1
