The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

车厢上方雕有三个分别象征着英格兰，苏格兰与爱尔兰的镀金小天使，他们高举着一顶镀金王冠。而在车厢前后，巨大的轮辐上方则隐现四位镀金海神，标志着不列颠是统治海上的无可争议的霸主。

The data from stress box indicate that the observed values usually are smaller than the theoretical ones, and the relationship between the vertical or lateral stress and the fill soil thickness can be described in a power function curve: cr= ahb. The fact that the soil stress is bigger in the portion adjacent to the central part of gully and becomes smaller in the portion close to the side illustrates that the gully has an apparent unburdening effect. From the monitoring results of the settlement deformation during and after constructingperiod, the study conducts statistical system analysis and evaluation on the change of settlement with time.

根据压力盒测试结果表明，测量值往往比实际的理论计算值小，填土的竖向和侧向土压力与填土厚度可以用幂次型曲线表示：σ=αh~b，愈向沟谷中心部位，土压力值愈小，愈向沟谷边缘，土压力数值越大，说明沟谷边坡具有明显的卸荷作用；根据施工期和工后期的沉降变形监测数据，对路堤内各测点的竖向沉降随时间的变化规律进行了数理统计系统分析和总结，工后期路面沉降和时间关系可用对数曲线表示：S=aln+b，并根据此沉降规律对高填方加筋土路堤的工后沉降进行了预测。

The result shew, Chromatin broke into pieces which dispersed around the irregular nucleus, nuclear outer member disintegrated; Mitochondria condensed, cristae of which disintegrated partly; The endoplasmic reticulum dilated, vesiculated, gradually disintegrated; A great number of dense granules appeared in the cell. To sum up: Enrichment of heavy metals in Eriocheir sinensis, Macrobrachium nipponease, Cipangopaludina cathayensis is obviou""

综上所述：我们首次证明上海地区沼虾、河蟹、园田螺对重金属元素富集能力要明显强于淡水鱼类；肝、鳃是鱼、虾、蟹体内重金属富集的主要部位；Hg和Cr为高富集元素，Cd是中富集元素，Cu和Pb为低富集元素；罗氏沼虾对镉离子和锌离子的96小时的半致死浓度（LC50）分别为0.115mg/L和0.68mg/L；首次证明锌离子、GSH在一定范围内可以抵抗镉离子对罗氏沼虾肝胰脏破坏。

The most important reasonwas the melting point of V2O5 only being 690℃, which could be volatilized as liquidstate if the temperature exceed this value and led to disastrous oxidation.

合金的 Cr 含量太低，不足以促成连续致密的 Al2O3膜的形成，故以掺杂作用为主，使合金的抗氧化性能降低。

The results showed that removal rates of five metals were 3.79%, 2.04%, 1.66%, 0% and 0%, respectively, under conditions of ultrasound time of 20 minutes. When nitric acid was added to the sludge, the removal rates were 2.32%, 40.67%, 68.15%, 26.98% and 27.24%, respectively.

结果表明，在超声时间为20分钟时，未加酸时五种重金属Cu、Zn、Pb、Cd和Cr的去除率分别为：3.79%、2.04%、1.66%、0%和0%，而加酸时其去除率分别为：2.32%、40.68%、68.16%、26.98%和27.24%。

采用该种焊接材料作为填充金属用于Cr-M。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
