Accordingly, to avoid future schisms it was first laid down that nobody was to be regarded as Roman pontiff unless he had been elected by two thirds of the cardinals (canon 1); all appointments by antipopes were deemed invalid (canon 2), heretics called Cathars were excommunicated and likewise were the bands of mercenaries, or rather criminals, which were causing utter destruction in some parts of Europe; it was declared, and this seems an innovation, that arms should be taken up against them (canon 27); it was also decided not to pass judgment about the preaching of the Waldensians .

因此，为了避免将来发生分裂，这是第一次订下的任何人都被视为罗马教皇，除非他已当选三分之二的枢机主教（佳能1）；所有任命由 antipopes 被视为无效（佳能2），所谓的异端 cathars 被驱逐，并同样被乐队的雇佣军，或者更确切地说，罪犯，其中造成极大破坏，在部分欧洲，它被宣布，这似乎是一个创新，即军控应采取行动对付他们（佳能27 ）；会上还决定，没有通过判决对说教的

He thought about doing it with Shareef, and was wise to pass, in retrospect. He got by one year with Mikki, got by another year with Cliffy. He busted with Marc Jackson.

他曾经考虑过Shareef又作罢，现在回过头看来这一选择是明智的，他用MM将就了一年，也用Cliffy将就过一年，他跟Marc Jackson崩了。

Came in March 2008 in June, the attention that Z and C never pass pair of Www.176pet.com laxly and newer, do not advocate exceeding SEO, but the thing that how holding to spend is a special difficulty, excessive optimize, can be indexed prop up a repulsion by search for certain, the station that a lot of people say me by Baidu K, perhaps be you fail to had held to spend, perhaps be you those who disobeyed search engine is certain collect regulation, the proposal watchs stationmaster network more (Www.admin5.com), engine of much all alone seeing search collects a guideline, optimize appropriately, be necessary, build up from nothing after all, careless root people the conduct propaganda that do famous website without too much capital, go Baidu, Google, Yahoo makes key word rank, and new station should stand firm, can friendly do well with each big search engine this kind of delicate concern also is crucial.

2008年3月至6月，Z和C从来没有松懈过对www.176pet.com的关注和更新，不提倡过度的SEO，但如何把握好度是一件非常困难的事情，过度优化，肯定是会被搜索引擎所排斥的，很多人说我的站又被百度K了，也许就是你没能把握好度，也许是你违反了搜索引擎的某些收录规则，建议多看看站长网(www.admin5.com)，多看看搜索引擎收录指南，适当的优化，是有必要的，究竟白手起家，草根们都没有太多的资本去做闻名网站的宣传，去百度、google、yahoo做要害字排名，而新站要站稳脚跟，能友好的和各大搜索引擎搞好这种微妙的关系也是至关重要的。

In the phase space spanned by the first 8 EOFs generated from the 20-day low-pass filtered data, the six rainfall regimes were id entified by applying a cluster analysis method, namely, the northeastern China regime, Yellow River regime, Qinling-Huaihe regime, Yangtze River with its south regime, Southern China regime, and rainless regime.
