Duck virus hepatitis ( DVH) caused by duck hepatitis virus type ⅰ( DHV-ⅰ) is a highly mortal infection disease.

Ⅰ型鸭病毒性肝炎是由Ⅰ型鸭肝炎病毒引起的雏鸭高度致死性传染病。

A Development of the Conventional DVH& Function Dose-volume Histograms

剂量体积直方图的扩充&功能剂量体积直方图

But conventional DVH is not suitable in the case when the normal organ function is non-uniformly distributed within the organ.

但是传统的DVH〔1〕都是未考虑到正常器官功能区域分布不均匀性这一特点，故在利用放射线对病人照射时引起了不必要的损伤。

Duck viral hepatitis ( DVH) is an acute, high-touch and mortal infectious disease caused by DHV which usually lead to high mortality in infant ducks. It is believed the primary disease threatening to duckery.
