unblended

This paper presented design of a magnetic wheel driven automatic scan device utilizing magnetic belt navigating, fiber sensor examining in order to the weld seams of high pressure container which often exist boundary unblended, unweld, crack etc.

针对高压容器焊缝常存在边界未融合、未焊透、裂纹等危害性缺陷，设计了一种利用磁带导航、光纤传感器检测、磁轮驱动的自动扫查装置。

Ultrasonic tandem method is usually adopted to detect the weld seam of a high pressure container in which dangerous flaws exist, such as boundary unblended and crack.

高压容器的焊缝常存在边界未熔合、未焊透、裂纹等问题，一般利用超声波串列扫查方法对焊缝进行无损检测。

The results show that no evident relationship exists between the index of the unblended coal and its coke strength, but there is a good relationship among more indexes.

实验结果表明：单一的煤质指标与焦炭强度的关系不是很明显，选用煤质多因素指标进行焦炭质量预测，其预测效果较好；
