trc的翻译

when the black point luminance was as small as possible, the white point luminance met the requirement of the application while the trc did not cross the discrete integer value axis or luminance axis, the display achieved the best settings with respect to brightness and contrast.

通过亮度、对比度设置使黑点亮度尽可能小，白场亮度达到使用要求，同时TRC不出现横剪切和纵剪切现象，则显示器达到了最优化设置。

results both parotids imaging and trc of radionuclide dynamic scintigraphy were all normal in 10 cases of controls. in 40 cases of patients with ss, 34 cases were abnormal imaging, and the abnormality rate was 85.0%.

结果10例正常对照者双侧腮腺核素动态显像的系列影像结果与TRC均正常，40例干燥综合征患者中，显像结果异常者34例，异常率85.0%；

a kind of driving circuit of the stepper motor adopting permanent flow and cut waves technology was introduced, for which trc was used to control the voltage of power in order to improve the frequencies characteristic of stepper motor.

介绍一种采用了恒流斩波技术的步进电机驱动电路，该电路的电源电压使用TRC（TimeRationControl）控制来改善步进电机的频率特性；
