Using manganous sulfate solution as precursor, Mn2+ was converted to Mn2 by the addition of ammoni, then Mn2 was oxidized to Mn3O4 with microwave irradiation.The rea-brown Mn3O4 powder was obtained.

论文在微波辅助加热条件下，向净化后的硫酸锰溶液中滴加氨水，使溶液中的Mn2+沉淀为Mn2，利用空气氧化Mn2得到Mn3O4沉淀，过滤，洗涤，干燥后得到棕红色四氧化三锰固体。

The meridionally accelerated axial-flow fans including meridian acceleration rotor, vaneless diffuser and volute was numerically simulated in the whole flow passage by Reynolds time-averaged N-S equations with tensor and k-ε turbulence model.

采用三维雷诺时均N-S方程和标准k-ε湍流模型，对包含叶轮、无叶扩压器与轴向蜗壳于一体的子午加速风机进行了整机全流道的数值模拟。

The theoretical analysis shows that the wave-activity relation presented a nonconservative form in which the pseudoenergy wave-activity density is composed of disturbance kinetic energy, available potential energy and buoyant energy. The local change of pseudoenergy wave-activity density depends on the combination of shear of zonal basic flow, Coriolis force work and wave-activity source or sink as well as wave-activity flux divergence.

理论分析表明，拟能量波作用方程具有非守恒形式，其中的拟能量波作用密度主要由扰动动能、有效位能和浮力能三部分组成；拟能量波作用密度局地变化除了受拟能量波作用通量散度影响之外，纬向基本气流切变、科氏力作功以及由非绝热加热和水汽相变所构成的波作用源汇项对其也都有贡献。

On this particular night three of them oared their way to the end of the lake where Amazon was based,hoping to find the enemy ship unguarded,capture her and bring her away.

就在这天晚上，他们三人划船向湖的尽头进发，亚马孙号船停泊在那里。他们希望发现、缴获并且带回这艘未加警戒的敌船。

A new direction of arrival estimation method is proposed using a single vector hydrophone, which is composed of three spatially co-located but orthogonally oriented velocity hydrophone plus another co-located pressure hydrophone.

摘要提出了一种基于单个矢量水听器的二维波达方向估计方法，该矢量水听器由三个空间轴向垂直的振速水听器和一个声压水听器构成。

Methods A 3-D finite element model of the wrist based on CT scan images was established. The load transmission of carpus and the distribution of contact stress on radiocarpal joint under axial compressive force on metacarpals as well as the effect of transverse carpal ligament release on the displacement of carpal bones were computed and analyzed.

通过CT扫描图像数据对腕部进行三维有限元建模，计算并分析掌骨受轴向压力作用下正常腕部载荷传递及接触应力的分布，以及腕横韧带切开前后腕骨运动的变化情况。

Radman won't ever be the dead-eye 3 point specialist for us, because he will never get consistent playing time.

拉德再也没有向我们展示过他的三分绝技，因为他完全无法融进球队的进攻。

After 30 years'Rearm and Opening-up,the outlook on economic crime has been shifted from the traditional one to the modern one in the scholarly circle.

改革开放三十年来，学界实现了由传统的经济犯罪观向现代经济犯罪观的转换。

3 A jealous wife is heartache and mourning and a scourging tongue like the other three.

但是，嫉妒别的妇女的女人，令人心痛悲伤；她向众人传话的舌头，是一条鞭子，比这三件事更使我害怕
