It takes advantages of AR-quiver analysis and APR- tilting translation. We proved: if T_A is a tilting A-module over a path algebra of type A_n or a characteristic tilting A-module over a path algebra of type D_n,E_6,E_7, E_8,then there are points corresponding indecomposable direct summands of T_A in theτ- orbit of each edge.

通过对Dynkin型路代数的AR-箭图分析及利用APR-倾斜变换，证明了A_n型路代数倾斜模及D_n，E_6，E_7，E_8型路代数本性倾斜模T_A的一个必要条件是，在A的AR-箭图Γ_A的边缘的r-轨道都有T_A的不可分解直和项对应的点。

They swore an oath which none shall break, and none should take, by the name even of Iluvatar, calling the Everlasting Dark upon them if they kept it not; and Manwe they named in witness, and Varda, and the hallowed mountain of Taniquetil, vowing to pursue with vengeance and hatred to the ends of the World Vala, Demon, Elf or Man as yet unborn, or any creature, great or small, good or evil, that time should bring forth unto the end of days, whoso should hold or take or keep a Silmaril from their possession.

他们发的誓无人能够打破，是任何人都不应发下的；他们甚至以Iluvatar为名，声称如果不遵守它，永恒的黑暗将降临他们。他们以Manwe、Varda和圣山Taniquetil为证，发誓说：不管是谁敢持有、夺取或隐藏属于他们的Silmaril，不管对方是Vala，魔鬼，精灵或是尚未出生的人类，或是任何生灵，不管伟大还是渺小，善良还是邪恶，他们都将怀着复仇与憎恨直追他到天涯海角，世界末日。

The indication of anus preserved operation should be chosen according to clinical stage and biological characteristic of rectal malignancy; eversion and pull-through anus preserved colorectal anastomosis through anus is a better anus preserved operation for low rectal cancer.

根据直肠癌的临床分期和肿瘤的生物学特性选择保肛手术适应证，经腹、肛门齿线上直肠癌根治性切除，行肛门直结肠外翻拉出吻合是低位直肠癌较好的保肛术式。中国诺宇综合网http：//www.siaaa.com
