中古时期,樊氏家族本为南阳地方家族,迨于唐代开始定居洛阳,完成“中央化”,并在北邙山两次建立家族坟茔。居于两京,死葬北邙,使其成为了两京家族。对此类小姓家族而言,政局变动可说是牵动其行为的决定性因素。樊氏在室三女的迁葬,一方面是家族情感的体现,另一方面也是对家族墓地进行调整与整合的行动之一。樊氏或想借助两次葬地的选择与墓志的书写,改变家族的地域认同,迎合政治需要,让家族成为真正的“东京戚里”。樊氏虽非世家大族,但迁徙决策与葬地选择,亦与士族向中央的迁徙路径相符。可见在当时的背景下,某些选择与行动非世家大族所独有。

The present paper presents a new experimental method to measure the deceleration time history of projectiles penetrating into concrete in full-size test. The experiment can be carried out by using an onboard accelerometer to measure the projectile deceleration history and the data are transmitted to a ground recording system. With this experimental method, a series of tests on hemisphere-nose steel projectiles penetrating normally into plain concrete at the velocity region 150 - 400 m/s have been executed and the deceleration histories obtained. The high frequency portion in the deceleration data has been investigated and proved to be the structure response of projectile. The characteristics of deceleration history have also been analyzed and discussed.

作者： Wang Xianrong Chen xiaohu liu Zhuo (Department of Electrical Engineering)

Dynamic load flow technology can simulate actual frequency and load flow change when a load naturally varies and generator units adjust their power output by an adjustment system during a certain time. Dynamic load flow is a basic part of power system state and tendency analysis. In this paper, a dynamic load flow model and its solution method are first presented and discussed. Then, the application of dynamic load flow to a real power system is given as a demonstration.
