求翻译：为提高高温红宝石压标的准确度，有必要依据所含Cr3+的含量，选择对应的温度频移率才能对DAC内的压力进行准确的校正。是什么意思？

Contained the cr3 + content, to improve the accuracy of the high-temperature ruby ​​pressure the subject, it is necessary in accordance with the temperature of the corresponding frequency shift rate in order to the dac pressure accurate correction.

High temperature pressure to increase the accuracy of the Ruby, there is a need based on the included Cr 3+ content, choose the corresponding temperature shift frequency rate in order for the pressure DAC accurate calibration.

In order to enhance the high temperature ruby to press the sign the accuracy, it is necessary to rest on contains the Cr3+ content, the choice correspondence temperature frequency deviation rate can carry on the accurate adjustment to in the DAC pressure.

Ruby pressure for improving high temperature standards accuracy is necessary depending on the content of Cr3+, select the corresponding rates of temperature shift can accurate calibration of pressure within the DAC.
