The optimization method is an effective tool in back-analysis of displacements of roadway, choosing the bad iteration method will lead to many problems, such as slow constringent speed, bad stability of solutions, local minimization.

最优化方法是进行巷道位移反分析的有力工具，如果优化迭代方法选择不当，将导致迭代过程收敛缓慢、解的稳定性差、陷入局部极小值等问题，不能保证搜索到全局最优解。

The crystallitic carbon was prepared from anthracite by demineralization and carbonization,then the magnesium/carbon nanocomposites for hydrogen storage were manufactured through reaction milling of the mixture of magnesium,crystallitic carbon and aluminium under hydrogen atmosphere.

将无烟煤进行脱灰和碳化，制备微晶碳，再将微晶碳和铝添加到镁中，用氢气反应球磨法制取镁/碳纳米复合储氢材料。用透射电子显微镜、选区电子衍射、X射线衍射和差示扫描量热分析对储氢材料的粒度、晶体结构和放氢温度进行了测定。

A"subgrain Al layer"was usually observed at the Al side of a SiC/Al interface containing no"interface Si"; the layer was less than 1μm thick and a few degrees crystallographically misoriented form the Al matrix, with high density of dislocation generated in it.

在那些没有&界面Si&的真正的SiC/Al界面处靠Al一侧，普遍地形成一层厚度不到1μm的&亚晶铝带&，它紧靠SiC表面形成，与远离SiC的Al基体有几度的位向差。

Furthermore, we also observed a kind of medium type cells intermediate between squamous and cuboidal cells, whose cytoplasm and nucleus were much better developed than those of squamous cells but less well developed than those of cuboidal cells.

另外，我们还观察到一种介于扁平形细胞和立方形细胞之间的中间型细胞，其胞质和核的发育明显好于扁平形细胞，但比立方形细胞差。

In cuboidal cells the nuclear membrane sank downward dividing the nucleus into t wo or three segments and the perinuclear space and nuclear pores were wider than those in squamous cells.

他悟性差，没有意识到存在的危险。

Defensor Sporting midfielder Tabarè Viudez will be an AC Milan player;"There is not the signature yet, but the negotiation is about to be carried out, only the medicals and the contract are missing, it's a question of one or two days" has declared the uruguayan club chaiman Fernand Sobral"."

德芬索体育队的中场球员塔巴雷-韦德斯将要成为一名AC米兰球员：&到现在还没有签约呢，但谈判即将进行，只差体检和签合同了，可能会在接下来的一天或两天内进行。&乌拉圭德芬索体育队的主席费尔南德-索伯拉尔说。

A scan of the whole genome for digenic interactions detected considerable amounts ofsignificant epistatic gene actions.Furthermore,many homologous pairwise loci with sameepistatic types observed simultaneously in both years,undoubtedly indicating that realinteractions exist in the population.

以双向方差分析方法对全基因组进行两位点互作显著性检测表明，存在大量的基因上位性作用显著影响产量等性状(P＜0.01)，而且两年能重复检测到同一显著互作乃至同一互作类型影响各性状。

It is found that the design of reinforce-beam section dog-bone connection can transfer the yielding joint from flange welds to parent metal zone, which possesses better plasticity and avoid yielding joints in weak welds. This design also enables beam flanges to dissipate earthquake energy more effectuality and protects weak welds.

在弹性、弹塑性有限元分析的基础上，对狗骨式节点和翼缘增强狗骨式节点进行了承载能力对比分析，结果表明：翼缘增强狗骨式节点设计可以将梁柱翼缘焊缝的塑性铰有效的转移到塑性好的母材区域，避免了在薄弱的焊根部位形成塑性铰，保护了韧性较差的焊缝。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。

He gained a small fortune in real estate.
