In this paper,based on the concept,purpose and operation process of depreciation of fixed assets,the depreciation fund obtained from the depreciation method commonly used in water conservancy sectors is compared and analysed with its rebuilt value.
根据折旧的概念、目的以及固定资产运行循环过程，对目前水利系统普遍采用的折旧方法提取的折旧额与资产重置价值进行了分析比较，认为目前采用的折旧法给固定资产的周转带来很多不利影响。

窦性起搏对心室肌纤维自发节律位相重置性质的数值研究
The numerical simulating result: When the intensity of driving pulse current is lower than 14, phase resetting is odd resetting,otherwise, it appears even resetting.
本文应用Beeler-Reuter模型,选取损伤电流I=23μA,产生自发振荡,施加不同强度的电流脉冲刺激,研究窦性起搏对心室肌纤维自节律位相重置的过程,结果表明:当外加电流脉冲强度小于14时,体现位相奇重置,反之,体现位相偶重置,并给出位相重置函数。
