不起作用的

It has been warranted through experiments and practical application that rare-earths-high-aluminium heat-resistant nodular iron has some intrinsic properties which are worthy of reconimandation, namely,that it will not scale after long periods of use at 1050-1100℃, will hardly break while being hammered into castings, runners or risers as the high-temperature tensile strength reaches 14-19 kg/mm2 at 800℃ or≥l3.3kg/mm2 at 900℃, with the room temperature strength close to HT 30-50 and the unnotched impact str...

本文介绍了稀土高铝耐热球墨铸铁的生产实践、化学成分；探讨了稀土作用及其用量和控制；论述了稀土和铝加入方式以及冷却速度对金相组织的影响；并对铸造工艺、铸件缺陷及分析、耐热性能及使用效果作了阐明。试验和使用证明：稀土高铝耐热球墨铸铁在1050～1100℃长时间工作不起氧化皮，热强度800℃时，14～19kg/mm~2，900℃时≥13.3kg/mm~2，室温强度近于HT30—54，a_k≈2～6kg·M/cm~2，锤击铸件或浇冒口，很难碎裂，并能机械加工。可以认为是以我国富产资源为原料，能用各种炉子熔炼、耐热和综合机械性能均较高硅、中硅中铝球铁、高铝片墨铸铁为高的一种耐热铸铁，也是镍铬系耐热材料较好的替代品。

It is true that outside forces, such as foreign Sunni jihadists and Shia militias supported by Iran, have played a part in fomenting the violence now under way.

确实，像外部的逊尼派伊斯兰圣战主义者和伊朗支持的什叶派民兵这样的外部势力，在挑起如今愈演愈烈的暴力事件方面起了不小作用。

Numerous infections have been suspected as environmental disease triggers, but none of them has consistently been incriminated, and it is unclear how so many different infections may play a role.

虽然人们怀疑众多的感染因素是环境疾病的触发因素，但还没有明确的归咎于任何一种感染因素，而且也不清楚如此多的感染因素如何起作用。

The rolling--ball flat--bottom mill shoe whose bottom face is overlaid with YD alloy is used to fully grind junks which is stuck downhole and impossible to be caught. Additionally, rolling balls which are dressed on cylinder face of mill shoe can guarantee the mill shoe not to mill casing inside wall during milling operation in hole.

滚球式平底磨鞋是用底面所堆焊的YD合金去全面磨碎那些卡死在井内无法打捞的钢铁落物，并且在磨鞋圆柱面上有可以起扶正作用的滚球，使磨鞋在井眼内工作时不磨铣套管内壁。

Thirdly, it is not criticism, the decisive factor that the astricts the arists' creativity, but the genius.

第三，是艺术家的才能，而不是评论家的评论，对艺术家的创造力起决定性作用。

The author is a Mormon, which means a lack of actual sex in the whole thing - except later in the books, where some very weird fetishes come into play.

作者是个摩门教徒，这就意味整个故事中不会有性方面的内容——除了在后续小说中有一些奇怪的事发生，而且还是一些奇怪的外在事物在起作用。

The control chart based on the geometric distribution(g-type chart) has shown to be competitive with p or np chart for monitoring the proportion especially for application in high quality manufacturing environments. However when the cases with LCL=0 occur, plotting values beneath the LCL is impossible given the non-negative nature of units, such type of lower control limits no ability to detect rate increase.

但是由于几何控制图的自然下限的问题，在其使用过程中若控制下限LCL＜0，则取其自然下限为0，这使得几何控制图在此情况下对于检测不合格品率p的增加是几乎不起任何作用，而此问题也是实际中我们最需要检测并作判断的问题。

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

Critics contend that the selection of the winners often has leas to do with true writing ability than with the peculiar internal politics of the Academy and of Sweden itself.

批评者们争论说：评选获奖者时，起作用更大的不是真实的写作能力，而是该委员会以及瑞典特有的内部政治。

Much the same argument can be made for lessors that provide vendor financing programs and services, but with an important, if obvious, caveat: the "build it and they will come" approach is not likely to work in China.

对于提供卖主融资计划和服务的出租人来讲，会有许多同样的说法，但带有重要而明显的告诫：&筑巢引凤&的方法在中国不太可能起作用。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.
