The appearance of heterojunction high electron mobility devices has made the new vigor poured into the development of GaAs MMICs. Pseudomorphic high electron mobility transistors have outstanding high-frequency characteristics, power characteristics and low-noise characteristics. And these merits have made the PHEMTs one of the most promising devices.

异质结高电子迁移率器件的出现给GaAs MMIC的发展注入了新的活力，赝配高电子迁移率晶体管具有优异的高频特性、功率特性和低噪声特性，使其成为现今微波单片集成电路发展中最具应用前景的器件之一。

Compound semiconductor devices are key parts of RF communication applications because they have advantages of high electron mobility, high working frequency, low RF loss, high linearity and low noise. It is so-called "pHEMT" for full name "Pseudomorphic High Electron Mobility Transistor".

中文摘要Ⅲ-Ⅴ族化合物半导体材料所制成之元件，具有高载子迁移率、工作频率高、射频损耗低、高线性度、低杂讯等优势，使得Ⅲ-Ⅴ族化合物半导体元件成为现今射频通讯应用之关键部份。pHEMT为假晶高电子迁移率电晶体之简称。

Results bFGF 2.5ng/mL promoted ECV-304 cell migration. Cell pseudopodia was increased and cell skeleton was rearranged.

Basically, the distribution patterns of most trace metals can be divided into iron style and manganese style, both of which were controlled not only by their different remobilization degrees, but the different input from coal mining drainage, mainly influenced by pH.

Fe型元素与Mn型元素分布差异的原因可以简约的概括为：锰的界面循环极为强烈，导致再迁移程度很高；而铁的循环相对较弱，又容易受到上层硫酸盐还原作用的抑制，因此再迁移程度不高。

Methods Porcine coronary SMCs were incubated with serum-free medium containing different concentrations of simvastatin. Infiltration of 3H-TdR into SMC DNA was measured as an index of cell proliferation. Simvastatin's effect on migration was tested with Sarkar's technique.
