Simulation of the - coincidence detection efficiency in activation measurment for neutron yield 符合探測效率的模擬計(jì)算
However , the calibration of detection efficiency in tgs is more difficult and complicated than that in the conventional method Tgs測量與常規(guī)能譜測量不一樣的是:探測效率的刻度極為困難。
The location accuracy and detection efficiency will be reduced when the lightning stroke occurs outside of the network or when not all of the stations are operative 假如閃電發(fā)生在網(wǎng)絡(luò)以外或有些探測站不能正常運(yùn)作,閃電定位的準(zhǔn)確度及閃電探測效率會較低。
After analysing the being pattern matching algorithm , under the circumstance of main string is very long and patterns is shorter , this thesis introduces a improved bmh algorithm , enhancing detection efficiency 在分析比較了已有的模式匹配算法后,提出了改進(jìn)的bmh算法,提高了檢測效率。
The detection efficiency was also obtained experimentally using radioactive source 60co . it was shown that the calculated values fitted the experimental data very well with the relative deviation less than 5 % 將mc模擬計(jì)算的探測效率與實(shí)驗(yàn)得到的探測效率進(jìn)行了比較,兩者相對偏差小于5 。
The results show that : monte carlo method used to obtain tgs efficiency is feasible and reliable , and is the only practical method of determining detection efficiency in tgs 表明了用mcnp4b方法刻度tgs探測效率的可行性和可靠性。中國原子能科學(xué)研究院博士學(xué)位論文2 .關(guān)于tgs透射測量問題,它與一般的ct測量相比,在原理上相類似。
We have calculated the variety rules of detection efficiency with the samples of various components and densities and sizes on different energy points , gained the factual results , and resolved the difficulty of the experiment 模擬計(jì)算了探測效率隨環(huán)境樣品成份、密度及樣品體積的變化規(guī)律,得出了具有實(shí)際意義的結(jié)果,解決了實(shí)驗(yàn)中制作各種標(biāo)準(zhǔn)樣品的煩瑣問題。
My thesis focuses on analysis network audit data using data mining , and mine rules about intrusion detection . intrusion detection efficiency is improved by using machine learning methods , thereby enhance adaptation of intrusion detection 本文主要從數(shù)據(jù)挖掘的角度對網(wǎng)絡(luò)數(shù)據(jù)進(jìn)行分析,發(fā)掘出入侵檢測的模型,用機(jī)器學(xué)習(xí)的理論改進(jìn)入侵檢測的效率,提高入侵檢測的自適應(yīng)性。
Abstract : in order to demonstrate the implementation scheme of the automatic system for telephone trunk , the implementation is discussed from the software and the hardware , and it is proved that the detection efficiency and precision of the system are preferable 文摘:對局間中繼線路自動偵測系統(tǒng)的實(shí)現(xiàn)方案進(jìn)行論證,從軟件和硬件方面進(jìn)行探討,證明該系統(tǒng)有較好的檢測效率和檢測精度。
