Analyzing and simulating of the deformation law of the ceramic downspout product after overcoming the shortage of powder material models in the software of MSC. MARC. It shows out the important effects of various factors and the shape of mandril during the process. And it is obvious that the shape of the top mandril has more effects on the process than the bottom.(3) Showing out the important effects of model figure on the flowing of powder and the forming of low-density fields from the analysis. After changing the top of the mandril into spherical shape, an improving model is putting out so that the distribution of stress and strain turns to be even and proper and that the flow rule of powder grains is better.(4) Calculating of the dimensional precision and the cutting ratio of the product and analyzing of the effects of such factors as rubber aging, loading process, mandril, friction etc. on the cutting ratio.

MARC存在的粉末材料模型方面的设计缺陷后,对连铸水口粉末成形件的变形规律及影响因素作用进行了模拟分析,指出芯棒形状对成形件的变形有较大影响,并且芯棒顶部形状与芯棒底部形状相比,对粉末变形有更大影响;(3)分析了成形件出现低密度区域的原因,指出模具形状对粉末流动以及粉末成形件低密度区域的形成有重要作用,提出了密度分布优化改进模型:改进模具顶部形状,并将芯棒顶部设计成球面后,粉末成形件顶部区域的应力、应变分布更加均匀、合理,粉体颗粒流动情况明显改善,低密度区域明显缩小;(4)计算了成形件的尺寸精度及切削率,并指出除模具形状的影响外,充填密度、橡胶模具老化、加载工艺等其他因素对总体切削率也有相当的影响。

Results show that gas release in gassy sand will cause the additive deformation of tunnel and additive stress of the shield segment, and make important impacts on the global displacement of tunnel but little influences on the stress of shield segments and the relative displacement of tunnel. It is inclined to arouse the differential settlement and cracks on the tunnel so as to cause hazardousness. Re-accumulating of the gas can also produce additional stress and the additive resilience, but it can be ignored in practical engineering because the influence degree is small. The shallow gas in reservoirs is appropriate to be discharged before construction of the subway tunnel.

研究结果表明:气体释放将引起隧道产生附加变形和管片附加应力,浅层气体释放对地铁隧道结构应力和结构相对变形影响较小,而对隧道整体位移影响较大,易引起不均匀沉降,导致隧道裂缝或断裂,进而引发危险;气体重新回聚时,隧道产生的附加应力和回弹位移量较小,工程中可不予考虑;地铁隧道施工前,宜对浅层气体进行预先排放。

Long periods of seeming invincibility. Though some industries or lines of business exhibit characteristics that endow leaders with virtually insurmountable advantages, and that tend to establish Survival of the Fattest as almost a natural law, most do not. Thus, for every Inevitable, there are dozens of Impostors, companies now riding high but vulnerable to competitive attacks. Considering what it takes to be an Inevitable, Charlie and I recognize that we will never be able to come up with a Nifty Fifty or even a Twinkling Twenty. To the Inevitables in our portfolio, therefore, we add a few "Highly Probables."

在所属的产业都被赋予其无可取代的优势地位,大者恒存的自然定律似乎牢不可破,但实际结果却不然,也因此在找到真正的真命天子之前,旁边可能还有好几打假冒者,这些公司虽然曾经红极一时,但却完全经不起竞争的考验,换个角度来看,既然能够被称为永恒的持股,查理跟我早就有心理准备,其数量绝对不可能超过五十家或甚至是不到二十家,所以就我们的投资组合来说,除了几家真正够格的公司之外,还有另外几家则是属于极有可能的潜在候选人。
