分别采用偏光显微镜和自主研制的焦炭综合热性能检测装置，检测焦炭的光学组织含量和变温-恒温条件 下的综合热性能指标。 结果表明：代表光学组织综合性质的各向异性程度指数OTI与表征溶损行为的综合热性能指标 起始反应温度Ti、平均溶损速率CRR25和等溶损反应后强度CSR25之间是抛物线关系，各向异性程度适中的焦炭起始 反应温度Ti和平均溶损速率CRR25较低，等溶损反应后强度CSR25较高。 OTI与Ti和CRR25的抛物线关系存在奇异点 （J4 焦炭），可能与光学组织测定方法自身的局限性有关。 OTI指数与表征耐高温特性的综合热性能指标—— —热处理性 指数CPHTI和热处理后强度CPHTS分别呈抛物线关系和逐渐衰减的指数递增关系， 但同样存在奇异点 （J4和J5焦 炭），这可能与光学组织自身组成和气孔、矿物质等其它因素有关。

The content of optical texture and the comprehensive thermal properties of coke under the condition of variable temperature constant temperature were detected by polarizing microscope and the self-developed coke comprehensive thermal properties testing device, respectively. The results show that there is a parabolic relationship between OTI, which represents the comprehensive anisotropy degree index of optical texture, and Ti , the initial reaction temperature, CRR25 , the average dissolution rate, and CSR25 , which is the comprehensive thermal performance index characterizing the dissolution loss behavior. The initial reaction temperature Ti and the average dissolution rate CRR25 of coke with moderate anisotropy are lower, and the strength after iso-solution reaction CSR25 is higher. The parabolic relationship between OTI and Ti and CRR25 has a singularity (J4 coke), which may be related to the limitations of the optical tissue measurement method. OTI index has a parabolic relationship with CPHTI, a comprehensive thermal performance index characterizing high temperature resistance, and an exponential increasing relationship with the intensity CPHTS after heat treatment, respectively. However, there are also singularity points (J4 and J5 coke), which may be related to the composition of the optical tissue itself and other factors such as stomata and minerals.
