Contrast enhancement was substantially een across all three areas of interest, Wilke said. Anoa analysis of the 11 studies showed no significant difference (p = 0.014) in the aerage Hounsfield unit alue of the main pulmonary artery (380 HU), left pulmonary artery (382 HU), right pulmonary artery (381 HU), distal pulmonary arteries (354 HU), proximal left main artery (410 HU), and the proximal right coronary artery (382 HU).

造影增强大体上正好可以到达三个需要注意的部位，Wilke说。11项研究的方差分析(p = 0.014)显示肺动脉主干（380 HU）的平均Hounsfield单位值没有明显不同。

For Hu invariant moment having no scale invariance, two modified algorithms are proposed: one is based on the normalized central moment coming from the concept of image square and the other is based on constructing a new invariant moment.

主要贡献如下： 1。针对离散情况下Hu不变矩特征仅仅具有平移、旋转不变性，不具有比例不变性的问题，提出了两种改进算法：一种是从图像正方形概念演变而来的归一化中心矩的修正；另一种是重新构造新的不变矩特征。

To determine the infection frequency of CVX-NTU and CVX-Hu in pitaya, samples collected from Yangmingshan orchard were detected by ELISA and one tube multiplex RT-PCR. Up to 95% of tested samples were infected with CVX-NTU and 35% contained CVX-Hu.
