For 100 mL wastewater in which the concentration of Cr is 62.6 mg*L-1 the best treatment conditions are that the mass ratio of iron chippings to cinder is 3 to 7, mass of the treatment agent is 6 grams, pH value is 5, treatment time is 10 minutes.

对于100 mL Cr浓度为62.6 mg*L-1的含铬废水，最佳处理条件为：铁屑与炉渣的质量比为3∶7，处理剂用量为6 g，废水pH值为5，处理时间为10 min。

The penile mass was located just proximal to the glans penis and measured 3 x 4 x 3 cm. Sonography revealed the mass to be located in the midline, displacing both corpora cavernosa laterally. It was well encapsulated, showing a uniform echo texture, isoechoic to the corpus cavernosum, with no involvement of Buck's fascia.

阴茎的肿块就位于龟头的近端，大小为3×4×3cm，超声显示肿块位于中线处，将两侧海绵体挤向侧方，其包膜清晰，回声均质，与海绵体呈等回声，未累及Buck筋膜。

The term combines the old English words for "loaf" and the Christian"mass", and in early church Lammas was the festival of the wheat harvest .

它是由两个英语单词结合而成的：loaf和mass。在早期教会里，&收获节&是庆祝收割麦子的节日。

First, we adopt MEMS technology to fabricate micro venturis with different widths of 150 and 200 um respectively and utilize FLUENT software to analyze the flow fields. Air was set as the working fluid and the air mass flow rate of inlet is changed to obtain the pressure drop between inlet and outlet. When a flow passes through the throat, the backflow results in the symmetric separations occur and grow with the increase of mass flow rate.

在微文氏管的研究部分，首先利用微机电制程技术制造出两种不同尺寸的微文氏管，宽度分别为150及200微米，开口角度各为45°，总长则为10 mm，再以空气作为工作流体，利用不同质量流率来量测微文氏管进出口的压力差并配合FLUENT软体分析观察其流场分布的情况。

The results show that in the applied load range of 10250 N, the mass loss rate of coated AZ91D alloy can be identified to three stages, which are related with whether the coating is worn out. Abrasion is the main mechanism for the coated alloy. The friction coefficient of the coated alloy during sliding wear appears oscillation before it reaches a constant value, which is close to the μ value of the matrix alloy. The mass loss rate of coated alloy increases slightly with increasing applied load when the applied load is more than 150 N because of high plastic deformation accommodation on the matrix alloy surface.

结果表明：根据载荷大小，涂层处理后AZ91D镁合金的磨损行为明显分为3个阶段，这些阶段同陶瓷层是否磨穿密切相关；微弧氧化涂层AZ91D镁合金的磨损机理主要是磨粒磨损；受表面状况的影响，陶瓷涂层的摩擦因数在 0.20~0.45 间波动；在较高载荷下，涂层被磨穿后，涂层的摩擦因数趋于基体合金的摩擦因数，涂层合金的表面变形能力提高，该阶段质量磨损速率随载荷增加，趋势变得缓慢。
