The max stress and the max radial displacement of conveyor is also proportional to the square of rotational speed. With the decrease of the blade thickness, both the stress and axial displacement of conveyor increase rapidly. The stress and radial displacement will increase with the increment of half cone angle and lead.

螺旋输送器的最大应力强度和最大径向位移均与转速近似地成二次方关系；减小叶片壁厚，沉渣对螺旋叶片作用的正压力所引起的叶片的最大轴向位移增长较快；正常工况下，螺旋输送器的最大应力强度和最大径向位移都随着半锥角和导程的增加而增大。

Because the increasing of dip angle can lead to special strata behavior which cause difficulties to mining, The strata behavior theory can not be simpely borrowed from that of flat and gently inclined seams. In order to cut down roof accidents and increase production efficiency, the strata movement and stress distribution must be reassessed for seam with deep dip angle.

煤层倾角增大带来了矿压显现的特殊性和开采上的困难，不能再简单地借用水平和缓倾斜煤层的矿压理论，而必须对大倾角煤层围岩运动与应力分布予以重新评价，以降低顶板事故，提高生产效率。

Meanwhile, the concentration of Pb,Zn and other heavy metals is rather high in the oxidation zone and decreasesdownward to levels that are unbelievably low for Pb-Zn mine tailings. Theseobservations suggest that heavy metals should be re-immobilized by secondaryminerals, rather than primary minerals, in the oxidation zone, and could be leachedout from suboxic environment due to low rate oxidative dissolution which preventsthe precipitation of secondary minerals in significant amount. Thus, cover scenarioswhich establish a suboxic environment beneath the cover layer might not always beeffective in preventing heavy metal release from mine tailings.Sequential extraction studies indicate that, in addition to heavy metal leaching,oxidation of the mine tailings increased the mobility of residual Zn, and Cu, while Pb remains immobile due to the formation of anglesite (PbSO4). Using the seven-step extraction technique developed by Dold (J. Geochem. Explor., 2003, 80: 55-68), galena dissolves in significant amount at step 2 most probably due to the strong complexing of Pb2+ by acetate, while other metal sulfides dissolve at step 6, which suggest that this extraction technique could not be used to evaluate the mobility of lead in natural environment

重金属含量均低于新鲜尾矿，但以硬化层中的含量最高(Pb、Zn含量分别为0.47%和0.93%)，往下大幅度降低，表明尾矿风化过程中形成的次生矿物对Pb、Zn等重金属元素有较强的固定作用，而次氧化带的淋溶作用造成了金属元素的大量流失；(4)与新鲜尾矿相比，硬化层中铅的可迁移性大大降低，硬化层之下尾矿样品中铅的可迁移性也不同程度降低，这是由于硫化物氧化产生的硫酸根与尾矿中的铅反应形成铅矾(PbSO_4)的缘故；(5)氧化作用使尾矿中的zn、Cu等重金属的可迁移性不同程度地增大，其中对锌的可迁移性影响最大，铜的可迁移性与铁比较相似，铅则容易与硫化物氧化形成的SO_4~(2-)反应形成铅矾(PbSO_4)；(6)为了减少尾矿污染和修复矿山环境，人们提出了各种不同的尾矿覆盖方案，本文的研究结果表明，这些方法不一定能够有效地阻滞污染元素的迁移。

In general, smaller grain size and greater angularity tend to increase the porosity while an increase in range of particle size tends to decrease porosity.

通常，颗粒越小曲率越大孔隙度越大，而当颗粒尺寸增大时孔隙度会减小。

Methods According to prescribed regulations, animalcule aerosol was used to test the person protection, product protection and crossed contamination under the condition of normal wind speed and increased contamination.

按照标准中规定的方法，使用微生物气溶胶进行评价，测试了正常标称风速下及增大污染机会的情况下的人员保护、产品保护和交叉污染。

Under the influence of increase in temperature with depth, the fluids are heated and the intraformation pressure is anomalously increased.

在随深度而增高的温度影响下，流体被加热，并且建造内的压力异常增大，因而加热了的流体穿透到断面的较高水平。

Answer 4: The mode of changeover will be analyzed and determined by the person solicited.

第二种方法可以缩短换乘路线，但是会增大车站的体量。

Methods Seven cadaveric spinal specimens were measured of neutrol zoneand range of motionin 6 movements including anteflexion,retroflexion,left and right lateral flexion,left and right axial rotation.

测试前屈、后伸、左侧弯、右侧弯、左旋转、右旋转的中性区(neutral zone，NZ)和运动范围(range of motion，ROM)。程序：完整状态；②骨折后状态；③椎体成形后；④3000次循环疲劳后。结果骨折后中性区和运动范围均明显增大。椎体成形后屈伸、侧弯、旋转在NZ及ROM均明显减少。

Results There were obvious mandible changes such as the increase of SNB angle and decrease of ANB angle and overjet after treatment with Twinblock, suggestive of mandible growth, increase of facial angle, reduction of mandible process angle, mild adduction of upper incisors, and mild anteversion of lower incisors.

结果 矫治前后下颌骨的变化具有统计学意义，表现在SNB角的增大和ANB角、OJ的减小，提示下颌骨的生长、面角增加和颌突角减小，上前牙轻度内收和下前牙少量前倾。

Results indicated that the content of polyaniline had significant influence on the anticorrosive performance of the coatings.

结果表明：聚苯胺含量对涂层的防腐蚀性能有较大影响，当涂层中聚苯胺含量较低时，随着聚苯胺在涂层中质量分数的增加，涂层的防腐蚀性能相应提高；随涂层中聚苯胺质量分数的进一步增大，涂层的防腐蚀效果开始下降；涂层中聚苯胺含量为5.0%时具有最佳的防腐蚀性能。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
