这减少了设备的厚度和电压损耗，从而降低材料的质量要求和探测器的材料成本。
This decreases the device thickness and depletion voltage and consequently reduces material quality requirements and cost of the detector material.
新的探测器在建造时使用了改进的电子设备和电池组，并且添加了新的的雷达高度计，这是一种发射微波测定两极冰层厚度的装置。
The new probe was built using improved electronics and batteries, and an extra radar altimeter, a device that will fire microwaves at the arctic and Antarctic ice to reveal its thickness.
但是，PIN探测器厚度有限，因而采用并联方法。
But, PIN detector thickness is limited, thus we used the parallel method.
