Inner insulation materials mainly include transformer oil, oil-paper and paper card.
Resistivity of materials is influenced by many factors such as temperature, humidity, electric field strength and time of power voltage, which results in nonlinearity of electrical field distributions under DC voltage.
In a word, electrical field distributions are resistive and imposed voltage of insulation materials is direct ratio with resistivity.
Electrical field distributions under AC voltage are mainly influenced by dielectric constant of insulation materials, effect on the constant by outside factors is very small, because the difference of the constant is very small.
Electrical field distributions of high-voltage windings are computed, whose superimposed voltage ratio of AC and DC is 1:3, and ratio of dielectric constant of insulation materials is 2:3:4.

Experimental Materials.
Due to the formation of bone-like apatite on the surfaces of materials is the key factor of the materials having bioactivities [2,3].
The XPS results also indicate that the treated materials compare with untreated materials, the surfaces form more bone-like apatite; the modification increases the bioactivity of the materials, which helps the formation and growth of the bone.

Study of Tribological characteristics of vegetable-based cutting fluids is essential to understand the behaviour of various materials under different operating lubrication conditions.
The complexity of predicting the wear and frictional performance of the materials motivates the tribologist to adopt an artificial neural network (ANN) approach, as it can be used to make such predictions with caution [7].

Introduction Droplet-based rapid prototyping is an additive manufacturing technique where objects are built from molten materials in a single operation without a mold or other tooling.
As we know, the surface tension, melting temperature, latent heat of solidification, and thermal conductivity of A2024 are higher than those of other low-melting-point materials.

Relaxation properties of the Solid Propellant Based on Hydroxyl-Terminated Polybutadiene Zhimin Xiea, Sichi Chenb, Youshan Wangc National Key Laboratory of Science and Technology on Advanced Composites in Special Environment, Center for Composite Materials, Harbin Institute of Technology, Harbin 150001, P.R.
The polymer-based propellant is a typical viscoelastic material.
Two experimental methods, quasi-static extension and dynamic mechanical analysis (DMA), are commonly used to measure the relaxation properties of the viscoelastic materials [3-5].
