心動過速可由於疼痛、恐懼、通氣不足或低血容量引起。Further investigated and analyzed composition structure and flow data that dsa ' s formation of image is systematic at first in this paper, carried on intact summing up to the data in the system, having given out the plan of design of high speed and large capacity data channel of digital formation of image system of x - ray ; deeper discussion of control way on sdram, give solution that many pieces of sdram works togetherses of realizing heavy capacity, designing of heavy capacity deposit board realize storing at a high speed to vision data by frame on the basis of this ; through further investigations of interface of pci bus, optimize back end state machine design and urge procedure making with lower, giving intact pci interface scheme that realize high speed dma data transmission and satisfy request of video transmitting ; further investigate the figure systematic design method of programmable logic devices, due to the difficult point of drifting about of enabled signal in fifo in common use and setting up and keeping of output signal, method has been proposed of improving stability of system making use of signal utilizing the phase locking ring in fpga to offer a lot of clocks to move thus realize coordinating the data between every module of system to transmit at a high speed by making use of fifo
本文首先對數字減影血管造影（ dsa ）成像系統的組成結構和數據流向進行了深入研究和分析，並對系統中的數據流向進行了完整的歸納和總結，給出了x線數字成像系統中的高速大容量數據通道的設計方案；在對sdram的控制方式做了深入探討后，給出了實現大容量多條sdram共同工作的解決方案，在此基礎上設計了大容量幀存板實現對圖象數據進行高速存儲；通過對pci總線介面的深入研究，優化後端狀態機設計和低層驅動程序開發，給出了完整的pci介面方案實現高速dma數據傳輸，完全可以滿足視頻傳輸要求；深入研究了基於大規模可編程器件的數字系統設計方法，針對通用fifo使能信號漂移、輸出數據難于建立和保持等設計難點，提出了利用fpga中的鎖相環提供多個時鐘相移的信號來提高系統穩定性的解決方案，從而實現利用fifo來協調系統各模塊之間的數據高速傳輸。The 3t3 mouse fibroblasts and human endothelial cells cultured on the surface of the implanted pp showed much better attachment and proliferation than that for controlled pp. at the same time, the cooft ion implantation also exhibited low macrophage attachment with normal cellular morphology. the above results can cause positive effects on the biocompa tibility when it is used as implant material
研究表明，離子注入后聚丙烯表面的親水性和血液相容性研究表明，通過對pp表面進行cooh ~ +離子注入處理，可以降低其表面能和水接觸角，提高其抗凝血性能和抗鈣化性能，並且pp的抗凝血性能與cooh ~ +離子的注入劑量具有很大的相關性。
