1·For all tests, when the power is on, the initial state of the curve tracer is assumed to be as follows.

对于所有的测试，当电源上，曲线的示踪剂的初始状态是假设如下。

2·The renal parenchymal ROI: drawing a closed curve excluding the renal pelvis detentioned the radioactive tracer.

肾实质ROI：沿肾皮质外缘亦勾画一个闭合的曲线，不包括有示踪剂滞留的肾盂。

3·This paper introduces a practiced method of calculating the tracer contour data of YX-173A cam milling machine from the discrete curve of brake cam contour, based on the copying principle.

应用连续曲线离散化思想，介绍了一种从已知工件轮廓曲线出发，按加工成形原理计算出YX -173A专用凸轮铣床仿形靠模轮廓数据的实用方法。

4·Different tracer curve types correspond to different reservoir types, providing reliable instructions for in situ profile control.

不同的曲线类型反映了不同的储层，从而有效指导现场调剖。
