And destruction usually occurs on angle.(2)Around the keyhole, the stress centralizes, column" edge opt to inflects in local.(3)The change of friction coefficients or bolt pretension forces can"t affect the performance of top-and-seat angel connections so much.(4)The parameters of angel influence joints performance greatly.

破坏一般是由于顶角钢上应力过大，形成塑性铰而导致的；(2)柱翼缘在与顶角钢相连的螺栓孔周围，存在应力集中，容易导致局部屈曲；(3)材料抗滑移系数的改变和螺栓预拉力的大小对于节点受力性能的影响并不明显；(4)角钢参数的改变对节点的各项性能影响显著，增加角钢厚度，节点的强度、刚度和延性都能得到明显的提高；增加角钢长度，节点的强度和刚度也有较大的提高，延性则略有下降；(5)柱轴压比过大时，节点的承载力、刚度以及变形能力明显下降；(6)螺栓中心线到角钢肢背距离增大时，节点的强度和刚度有所下降，但延性略有增加。

The results of the TG and DTG curves show that, in the whole intumescing process, APP, PER and MEL cooperate with each other and synergism is generated; The kind of base resin and its contents, the ratio of the component of fire retardant system and their contents all have great influence on the thermal degradation behaviors of fire retardant coating; The concentration of oxygen has no influence on the thermal degradation of fire retardant coating below 345℃, while the influence can not be neglected above 345℃, but compare with the factors mentioned previously, the influence is small.

研究表明，聚磷酸铵-三聚氰胺-季戊四醇三者能密切配合，对阻燃起到协同作用；基料树脂的种类及含量、阻燃体系配比及含量对防火涂料的热分解行为有较大的影响；氧气浓度在低温阶段(345℃以前)对热解行为几乎没影响，而在高温阶段(345℃以后)则对热解行为有影响，但相对于前面的因素对热解的影响来说，氧气浓度对防火涂料的热解行为影响较小。

It also makes it possible for relatively large images to be projected from a short distance away using the same sort of fish-eye lens used in planetariums to cast images at wide angles.

这还使得在采用和天文馆大角度投射图像中采用到的鱼眼透镜相同类型的透镜时，可以从短距离投射出相对较大的图像。

Further studies on biodiversity in the reforested land showed that shrub diversity increased but herb diversity decreased with reforested time. The evenness index changed little.

该流域人工林恢复结果表明，林龄的增加，土壤性质变化比较大，总氮含量与种植年龄呈现十分好的线性正相关，土壤质量也有较大的改善。

In the depth scope ranging from 1100 meters to 3500 meters, the direction of the middle principal stress becomes vertical.The simulation result, from the modelling of the Kun 2# drill and its vicinities, suggests that the vertical stress variation is relatively small in the place 3 to 7 times of the drill diameter from the well wall, but the horizontal stress varies in some trend. Moreover, the direction of the minimal stress component and the remote loading pressure take place large deviation in southeast direction.

而对昆2井及其周边地区建立了子模型进行模拟的结果显示，在距井壁3～7倍的地方，垂向应力变化相对较小，但水平应力则发生了不同程度和趋势的变化，另外，最小应力分量的方向与远源加载的压力在南东向发生了较大的偏转。

Study limitations include small sample size, exclusion of several potentially eligible children because of medication-related drowsiness or refusal to participate, limited ability to generalize the results, and testing of some children more than once resulting in a learning effect or decreased pain due to healing. Older children found the game too simple and therefore not as distracting as the younger children reported it to be. Because the VR equipment was not waterproofed, pain responses could not be determined through an entire dressing change, including during wound debridement in the bathroom.

这项试验的限制因素，包括样本数很小、排除许多潜在合适的儿童，因为药物相关的嗜睡或是拒绝参与试验，而限制了这个试验结果的普遍性，而且对许多儿童进行一次以上的试验会造成一种记忆效果，或是因为复原而减少疼痛；年龄较大的儿童觉得这些游戏太过简单，因此不像对年龄较小的儿童一样，那麼地吸引人；且因为VR装备不是防水的，因此疼痛反应不能在换衣服时评估，包括於浴室时清创时。

For LP casing of 50MW air cooling units,the internal 3-D flow field of the off-design simulated with Fine/Numeca,a 3-D CFD software,is introduced.

详细分析各工况下的三维流场信息，结果显示背压变化对末级的影响比较大，在高背压、小容积流量工况下，在末级动叶中部出现较大的分离区。

The anchor anchoring depths could be regard as critical value for concrete edge failure and anchor failure. When the anchor edge distance was shorter than anchor anchoring depth, the failure mode was concrete edge failure and anchor space length had some influence on cracking load. When anchor space length was longer than anchor anchoring depth, the failure mode was anchor failure.

锚栓的锚固深度可以认为是混凝土边缘破坏以及锚栓破坏的临界边距，对于锚栓边距较小的情况，以混凝土边缘破坏时的承载力为标准，锚栓间距对于试验的开裂荷载有影响；对于锚栓边距较大的情况，以锚栓的破坏为标准。

Large-span steel arch bridge are developing rapidly in recent years due to their aesthetic feeling and spanning capacity.

大跨径钢拱桥以其优美的造型和较大的跨越能力，近年来得到了迅速的发展。

In the paper, we investigate, respectively, the unsteady transport properties of heat and moisture in enclosure under constant wall heat flux and constant wall temperature when porous particles are small and Darcy number is lower, the effect of conductivity ratio, heating conditions and other parameters on the heat transfer rate of enclosure when particles are larger and Darcy number are higher.

并分别对多孔颗粒较小时的低Da数封闭腔内的非饱和渗流与传热，及颗粒较大的高Da数封闭腔内的非饱和自然对流行为进行了数值模拟，研究了低Da数时湿分与热量在恒热流与恒壁温条件下的非稳态传递特性，高Da数时封闭腔的传热与流动特性、达西效应以及导热比、加热条件等对空腔传热系数的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
