发帖数: 3 | 2 前面有网友在看完“潘伟平——长期迫害中国大陆学者、官司缠身、学术造假，营
造‘血汗实验室’，这样的人也配入选中组部千人计划？”一文后说，“就事论事，这
是在指责潘伟平在‘德’方面的问题，好像‘才’方面没提到。那么国家‘千人计划’
在德方面有哪些要求？好像没有嘛。”这位网友，谢谢你的回帖。下面我们提到潘伟平
“才”的一面。首先让我们回顾一下“千人计划”的基本要求。
“千人计划”是中国目前最高层次的海外人才引进计划。国家从2008年起，用五到
十年，引进一批战略科学家和领军人物回国创新创业。国家重视程度之高，投入力度之
大，远远超过“长江学者计划”。
“千人计划”设立四个平台，其中为高等学校和科研机构引进的海外高层次人才，
除基本要求外（年龄、学历、职称等），还需具备下列条件：
具有世界一流的研究水平，近五年在重要核心期刊上发表具有重要影响的学术论文；
获得国际重要科技奖项，掌握重要实验技能或科学工程建设关键技术。
潘伟平宣称的文章很多，让我们一一梳理，看他是否符合“千人计划”的条件。所

Synthesis
Each carbon filament is made out of long, thin filaments of carbon sometimes
transformed to graphite. A common method of making carbon filaments is the
oxidation and thermal pyrolysis of polyacrylonitrile (PAN), a polymer based
on acrylonitrile used in the creation of synthetic materials. Like all
polymers, polyacrylonitrile molecules are long chains, which are aligned in
the process of drawing continuous filaments. A common method |

Do you cellulose ethanol is not compatitive and higher cost than starch
ethanol with established platform except one company in German or Denmark
can marginally compete with starch etanol. Although cellulosic ethanol is a

发帖数: 773 | 21 Pyrolysis has too low product yields although it has low capital investment
and can use broad feedstock.
Sugary H2 production is a net energy gain process (output is 22% more than
input). No technology can achieve it before. Also, hydrogen is cleanest for
end users. It is why it will be a final winner compared to most energy
generation or conversion systems. |

有pyrolysis的方法直接做油类fuel的是吗？在现在的科技下，大家都是怎么利用纤维
素的？
还有，一般纤维素的工业来源是啥啊？algae?稻草？木材？玉米杆？都有啥好处坏处啊？
最近读文献，看到还有说有用cellulose-derived intermediate来进行精加工的。这种
中间物比如糠醛啊，levulinic acid等等。好奇这类中间产物真的就很便宜吗？一般都
是怎么弄出来的？
