On the Social Basis of the Lin Piao Anti-Party Clique
姚文元
by Yao Wen-yuan
[This article is reprinted from Peking Review, #10, March 7, 1975, pp. 5-10.]
毛主席在讲到必须搞清楚无产阶级对资产阶级专政的问题时明确指出：“林彪一类如上
台，搞资本主义很容易。因此，要多看点马列主义的书。”这就提出了一个极其重要的
问题：即“林彪一类”的阶级本质是什么？林彪反党集团产生的社会基础是什么？把这
个问题弄清楚，对于巩固无产阶级专政、防止资本主义复辟，对于坚定地执行党在社会
主义历史阶段的基本路线，一步一步地造成资产阶级既不能存在也不能再产生的条件，

都是日本领土。资料来源：日本外务省
http://news.ifeng.com/a/20150202/43077157_0.shtml
在自民党上月国会选举取胜的鼓舞下，日本首相安倍晋三再次立誓，定要将日本从往昔
的桎梏中解脱出来，尤其是要带领国家走出二战失败的阴影。安倍晋三和他的支持者们
将对那个时代的主流记述看作“自虐史学”，并认为正因如此日本人才难以对所谓的“
新日本”产生自豪感。他们提出要修改日本宪法第九条，即日本人民“永远放弃战争作
为国家的主权权力”。
去年4月，日本外务省在其官方网站公布了一幅日本地图，集中体现出开拓新日本的雄
心壮志。在这份被译成12种语言的地图上，日本的疆域超出了国际社会承认的边界。它
以“固有领土”的名义，将周边国家提出主权主张的许多岛屿统统划归日本所有。按照
日本的说法，这些地方都是日本国不可分割的一部分。
实际上，安倍政府的扩张主义观点反而有损于日本的经济和战略利益。

经文: 「耶和华释放被囚的。」（诗篇一四六：7）
还记得吗？上帝带以色列人出埃及，也曾释放被囚的耶利米、彼得等。祂今天
仍能行此大事，祂用口中的话断开铜锁，用火炬般的眼神断开铁链。祂现在正做此大事
，各地受捆绑的人，要奔向自由光明，耶稣为他们开了一条道路，监门因而大开，锁链
因而断落在地。
亲爱的朋友，若你现在正被疑虑恐惧牢牢辖制，耶稣乐意释放你，给你自由与
喜乐；不，你不用奋力去挣脱这捆绑，你尽管放松，耶稣自己要来替你松绑。只要单单
地信靠祂，祂会成为你的解放者；纵然有石墙铁链将你困住，撒但钩不到你，罪恶也不
能钩住你，绝望也无法淹没你。只要你现在相信主耶稣，沉浸在祂自由的恩典中，祂有
无比浩大的能力要拯救你。

引用 timmy发言：【加尔文主义者，也分很多种，或很多的层次。

1/ 超极端的加尔文主义者，认为得救是预定的，用不着传福音。现在是极少数极少数

2/ 较极端的加尔文主义者，认为亚敏流派、和大部分福音派是在严重错误中。现在欧

3/ 温和型泛改革宗，大体接受加尔文五点，但接受对其的各样修正。接受对圣约神学
的修正。这是大部分的福音派长老会。
4/ 泛归正派，接受加尔文五点中的三点或四点，参考圣约神学，同时也对其它神学体
系抱开放学习的态度。其中有浸信会、英国教会、公理会等。

发帖数: 2166 | 32 宿命论那是印度教吧，我个人认为是不符合佛陀的缘起法的。
不过我们的free will 也很有限。这个从缘起法里看的很清楚 －
那些是已经决定了 － 这当下一刻的六个感官感受，以及喜厌平和感都是已经决定了的。
什么决定的哪？
过去的所做所言所愿决定了我们的这一刻。
那些是自由意志哪？ 我们对这一刻喜厌平和感的产生反应。反应包括情绪(fetters)，
和情绪产生的思维，下的决心和执行的言行。
当我们有了情绪，做了决定，或者有了言行，这就是bhava, becomging. 这个就是新的
kamma 产生了。
如果对当下一刻只有喜厌平和感，而没有产生情绪，这就是pure mind, 即便做了事说
了话，那也没有创造新的kamma. 。
这个就是我们如何避免造业。也是修行要达到的境界。
根据缘起法看，我认为我们的自由意志令我们在娑婆世界周转。并非我们没有自由意愿
，而是它是我们的枷锁。
在这些自由意愿了，有一种叫做chanda, 就是修行的决心和努力，这个是wholesome 的
， 当然它还是创造kamma 的。 |

Check a review article by LJ FETTERS on macromolecules in (1994?, not so sure) |

hehe...Just check Fetters LJ's Macromolecules in 1994, 27(17): 4639.
you need to know the difference bettwen Me (entangled M) and Mc (critical M),
generally Mc=2-3Me

I am just wondering why Science and Nature so favor various experiments to
verify reptation theory.
seems this time, that guy together with Grest and Kremer used Fetters et al's
old concept of packing length to win a big deal...

他对于高分子合成和高分子物理两个方面都作出了基础的极重要的贡献。
罕见的全才。 |

发帖数: 12367 | 47 虽然有一些人试图用Kuhn length做点文章，试图把它作为使得高分子
链行为符合高斯链行为，但仍然不够清楚，或不够General。。。究其
原因，无非是因为在大部分polymer来说，Me挺低的，下面基本上没有
多少区间可供研究，也就PS和PDMS以及他们的一些改性的东东。。。
以我的看法，现在这个问题的重点应该先解决Me和Mc的区别的根本原因，
Fetters等人曾经有几片文章(Macromolecules, JPSB)讨论过用Packing
Length去说明之间的根本原因，好久没搞这冬冬了，不知道是否为众人
接受。。。。cashine，有没有什么input?

Tg is around 0 degree C.
however, it has a very strong dependence on 1,2-content.

北大百年的时候，他好像就带着去了的，不过那时候是作为女朋友介绍的
其实04年前后我就听说他是要作为DOE掌门人培养的
然后要先去national lab弄些administration的经验 |
