The high temperature materials, phased array sensor, and low current requirements stabilize the output signals over a wide range of input voltage, ambient temperature, or output frequencies.

高温材料，相控阵传感器，低电流的要求较稳定的输入电压，环境温度，或输出频率范围的输出信号。

Rock wool insulating tubes is basalt and other natural ore, etc as main raw materials, by high temperature melting in a fiber, stir-in binder, curing processing and is made.

岩棉保温管是以玄武岩及其它天然矿石等为主要原料，经高温熔融成纤，加入适量粘结剂，固化加工而制成的。

And because the gate and the insulation layer are formed right at the end of the chip-making process, after the high-temperature steps have been completed, it is possible to choose from a wider range of materials for the insulation layer.
