As the concentration of FeO increasing, the rate of decarburizing and reaction-dissolving of refractory rises sharply. Meanwhile gas production rate of reduction reaction is increased and motion and foaming of molten slag are also speeded up. The corrosion feature of refractory containing graphite carbon is that the most severity area is slag level (interface of slag-gas phas -refractory) and slag-metal interface comes second, and the lowest corrosion rate is the area of iron-bath.

熔体的组成、温度及熔体与耐火材料间的相对运动对耐火材料的侵蚀产生着很大影响，而熔渣中FeO浓度是最主要的因素，FeO浓度提高，使耐火材料脱碳和反应熔蚀速度呈直线上升，熔体中还原产生气体量增加，熔体涨泡及运动速度提高，这些作用都加快了熔体对耐火材料的侵蚀。

To explore the existence and dynamic changes of the Golgi body-like structure in the log-phase and encysting trophozoites (6, 12, 18 hours) of Giardia lamblia, these trophozoites were stained with C6-NBD ceramide, a specific marker for Golgi body in eukaryotic cells, and then they were observed with fluorescence microscopy.

It is found that before the pearlitic and upper-bainitic reactions, a pro-cutectoid orpro-bainitic phase is precipitated along the austenite grain boundaries in the cyanidedsamples; and it is thought that this is likely a nitrogen-bearing phase which provides thephase boundary effect for the nucleation of the reactions and impoverishes the parentaustenite in alloy content, thus accelerating the transformation of austenite.

实验中发现，在珠光体及上贝茵体形成之前，氰化试样中均有一种过剩相沿奥氏体晶粒边界析出。这种先析相可能是一种含氮的化合物，其析出为珠光体及上贝茵体的非自发形核提供了现成的有利界面，并使奥氏体合金化程度降低，因而加速了转变。

Addition of minor alloying elements can fine the structure of bainitic ferrite markedly. The bainitic ferrite is composed of subunits or subchunks. The carbides with different morphologies are distributed between the laths. inside the plates and at the boundaries of subunits. There are abundant fine structures in bainitic ferrite. In the primary bainite of Cu-Zn-Al alloy there are interfacial structure ledges.

结果表明：加入微量元素可以使贝氏体铁素体组织明显细化贝氏体铁素体由亚单元或亚块组成、碳化物形貌不一，分布在条间、片内和亚块边界贝氏体铁素体内有大量的精细组织。

Results:When wide-diameter implant or two-implant were used to replace single mandibular molar, the stress of implant-bone interface was much lower than that of standard-diameter implant restoration. Comparison between wide-diameter implant and two-implant replacement showed that the former created lower stress. The difference was more obvious under oblique loads.

结果：与单个标准直径种植体修复相比，采用单个大直径种植体或双种植体修复单个缺失下颌磨牙均可使种植体-骨界面应力值大大降低；而采用单个大直径种植体修复单个缺失磨牙时骨界面应力值相对较小，以斜向加载时更为明显。

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。

Acidizing and fracturing are performed on perforated Berea sandstone targets after perforating tests in labs.

在实验室条件下对贝雷砂岩进行射孔试验，并分别对射孔后的靶体进行酸化、压裂工艺处理，利用核磁共振和工业X-CT技术分别对未射孔的靶体、射孔后的靶体、射孔后酸化的靶体、射孔后压裂的靶体进行测试。

Tandem bluff bodies.It is found that:（1）occurrence of the self-excited flow between two tandem bluff bodies depend strongly upon:the Reynolds number, the streamwise spacing between two tandem bluff bodies, the vortex formation length of the single upstream bluff body, and the characteristic length of the downstream bluff body.

本实验结果显示：（1）双钝体间具有自激式振荡的流场特性归纳如下：雷诺数、双钝体间的纵向间距、上游钝体的涡漩形成长度、下游钝体相对之特徵尺寸等均是影响双钝体间自激式振荡特性的重要参数。

Proceeding from the thought of blasted fragments having the fractal characteristics, the calculation of blasted fragment sizes was related to the mechanism of blasting in jointed rock masses by the new concept of "rock mass fracture ratio" presented and , thus, the model of damage mechanics for blasting in rock masses was established, which reflects the blasting essence of both rock masses breaking along joint planes and rock breaking.

从爆破岩块具有分形特征的思想出发，通过提出&岩体破裂比率&概念，将爆破块度计算同节理岩体爆破机制相联系，建立起岩体爆破块度的损伤力学模型，该模型反映了岩体沿节理面破裂和岩石本身破裂的岩体爆破本质。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
