摘要：MCNPX is a general purpose Monte Carlo radiation transport code designed to track many particle types over broad ranges of energies and it has the potential to deal with Accelerator Driven System(ADS)*** neutronics design and analysis of ADS using MCNPX code is significantly complex mainly on constructing the three dimensional geometry model,especially when there is an additional spallation target coupled with the subcritical reactor constructed by abundant nested repeated structures in several *** modeling process has long been recognized as a time consuming,tedious and error-prone task,which is hard to master for novice ***,it is imperative to build a code system that can translate CAD models of ADS to the native language of MCNPX *** this context of demand,a code system named CAD-PSMC(FreeCAD based parsing script for MCNPX code)has been developed to solve the CiADS modeling conversion problems.

摘要：Genetic variations such as mutations and recombinations arise spontaneously in all cultured *** it is possible to identify nonneutral mutations by selection or counterselection,the identification of neutral mutations in a heterogeneous population usually requires expensive and time-consuming methods such as quantitative or droplet polymerase chain reaction and high-throughput *** mutations could even become dominant under changing environmental conditions enforcing transitory selection or *** propose a novel method,which we called qSanger,to quantify DNA using amplitude ratios of aligned electropherogram peaks from mixed Sanger sequencing *** expressing enhanced green fluorescent protein and mCherry fluorescent markers were used to validate qSanger both in vitro and in cotransformed Escherichia coli via quantitative polymerase chain reaction and fluorescence *** show that qSanger allows the quantification of genetic variants,including single-base natural polymorphisms or de novo mutations,from mixed Sanger sequencing reads,with substantial reduction of labor and costs compared to canonical approaches.

摘要：随着科学技术与现代社会的发展,电子计算机的应用越来越普及。计算机英语专业也逐渐成为一门专门的学科。目前已经有大学、中专、职业中学开设计算机英语专业,下面就有关词汇进行探讨。一、词的组合在计算机英语中,将几个词组合在一起构成词和词组的现象特别多,如“名词+形容词”:time-consuming(花费大量时间的);“形容词+名词”:highlevel-format(高级格式化)、remote terminal(远程终端)、main frame(主机)、master disk(主盘)、host program(主程序);“名词+名词”:work
