现在我们已经知道了这个标签的尺寸，让我们将基线放置在距离图像顶部40像素的位置并使其水平居中。
So now that we have the label dimensions, let's place the baseline 40 pixels from the top of the image and center it horizontally.
以焊接处微观结构缺陷尺寸作为初始裂纹尺寸，采用基于裂纹闭合的全寿命预测模型，以焊接区域不同位置的长裂纹扩展速率曲线作为基线，利用J。
Fatigue life prediction from the initial crack size to failure based on long crack propagation at different zones of welded joint was made by using j.
