    • A technology described herein is for accurately determining the SOC of a secondary battery. An open-circuit-voltage-to-state-of-charge (OCV-SOC) characteristic has a capacity decrease estimation OCV region in which a relationship between the OCV and the SOC is assumed not to change due to degradation of the secondary battery 1a since a reference time point. Charge currents or discharge currents in the capacity decrease estimation OCV region are accumulated in a process in which the secondary battery SOC changes among OCVs. From the accumulation, an accumulated current is obtained. A secondary battery capacity decrease is estimated based on the accumulated current. An OCV-SOC characteristic is specified based on the estimated secondary battery capacity decrease and a predetermined relationship between the battery capacity decrease of the secondary battery since the reference time point and the OCV-SOC characteristic. A secondary battery SOC is determined based on the OCV and the specified OCV-SOC characteristic.
    • 本文所述的技术是用于准确地确定二次电池的SOC。 开路电压到电荷(OCV-SOC)特性具有容量降低估计OCV区域,其中考虑到OCV和SOC之间的关系不会由于二次电池1a的劣化而改变 因为参考时间点。 容量减小估计OCV区域中的充电电流或放电电流在二次电池SOC在OCV之间变化的过程中累积。 从积累中获得累积电流。 基于累积电流来估计二次电池容量的下降。 基于估计的二次电池容量减小和从参考时间点起的二次电池的电池容量减小与OCV-SOC特性之间的预定关系来指定OCV-SOC特性。 基于OCV和规定的OCV-SOC特性确定二次电池SOC。

    • A trace guide (TG) that has been set within a manual trace reference cross-section (58) is illustrated with a dashed line. The trace guide (TG) is obtained from three-dimensional contour information based on already-completed manual tracing of a first sheet. Therefore, the user draws a trace line (TL) corresponding to the contour of target tissue on a second sheet of the manual trace reference cross-section (58) while referring to the trace guide (TG) and also checking a tomographic image of the target tissue within the manual trace reference cross-section (58). The user may: draw the trace line (TL) in full; use apart of the trace guide (TG) without alteration as the trace line (TL) and correct the remaining part to serve as the trace line (TL); or use the trace guide (TG) without alteration as the trace line (TL).
    • 已经在手动轨迹参考横截面(58)中设置的轨迹导轨(TG)用虚线示出。 跟踪指南(TG)基于已经完成的手动跟踪第一张纸的三维轮廓信息获得。 因此,在参考轨迹导轨(TG)的同时,用户在手动轨迹基准横截面(58)的第二张纸上画出与目标组织的轮廓相对应的轨迹线(TL),并且还检查 目标组织在手动轨迹参考横截面(58)内。 用户可以:绘制轨迹线(TL); 使用跟踪引导(TG)作为跟踪线(TL)而不改变,并将其余部分作为跟踪线(TL)进行校正; 或使用跟踪指南(TG)作为跟踪线(TL)。
