Numerical methods based on the continuum hypothesis and molecule kinetic theory are performed to investigate the gaseous flow in the microchannels. The validity of different boundary conditions based on continuum model is examined by DSMC method under different Knudsen number. It is found that the impact of rarefied and compressibility effects are different.

Normal human fibroblast spheroids were self-assembled and cultured for 1, 4, or 7 days, then combined in trough shaped recesses. Over a 24-h period the spheroids fused to become a rod shaped microtissue and the kinetics and extent of fusion could be quantified by assessing rod contraction.

正常的人成纤维细胞可自我聚集形成球体，并培养了1、4、7天，然后在槽状的凹处中进行结合。24小时时间段过后，球体融合成柱状的微组织，融合的动力学及程度可以通过评定这种小柱的收缩而进行定量分析。

Assuming fluid is and viscid and slightly compressible, bubble collapse near rigid boundary and free surface is simulated, displaying characteristics such as formation, penetration and impact of reentrant jet as well as vortex ring and bubble rebound.

采用粘性、微可压流体模型，数值模拟了空泡在刚性边界和自由面附近溃灭及空泡溃灭后流动的发展，显示了空泡溃灭过程中的凹陷射流形成、空泡贯穿、射流冲击、涡环的形成和空泡回弹等流动特征，提出空泡回弹的另一种机制是凹陷射流冲击形成的旋涡。

This paper introduces an advanced oil-mist lubricating manner, discusses the possibility of applying auto-oil mist lubricating to tobacco machine tools, researches the working state by comparison,and testifies to this way in saving lubricating oil,prolonging machine tools life,and improving product quality.

介绍了一种先进的油雾、油气润滑方式，探讨了对烟机切刀进行自动油雾润滑的可行性，对比研究了其润滑工况，证明采用该润滑方式可省润滑油用量，提高产品质量，延长切刀使用寿命。还简单介绍了相应的单片机控制的微油雾润滑系统的开发

As title said, microblogging is a movie star in my eyes the place, for me, its greatest significance lies in allows you to spend more on the web tracked boring, I can more easily make a few is not responsible for words, do not twist ...

如题所说，微博在我眼里就是一个搬弄是非的地方，对于我来说，其最大的意义在于可以让你在网上的无聊消磨更加有迹可循，我可以更加轻松地发表一些不负责的言论，不用绞。。。

As the replacement material of cement and concrete, superfine slag powder is widely used for it can be employed to improve the strength of cement and the durability of concrete.

矿渣微粉作为生产水泥的原料和混凝土的掺合料，可有效提高水泥的强度和改善混凝土的耐久性。

It is concluded that the ~(176)Hf/~(177)Hf ratios of 91500, Temora and We-1 were homogeneous, because the aforementioned Hf isotopic results consist of at least seven separated performances of aliquots for each zircon sample. These results have significant implications for zircon Hf isotopic determination by using LA-MC-ICPMS.

上述每个结果包括至少7组独立的锆石样晶的溶解、分离和测定，表明标准样91500、Temora和We-1是Hf同位素组成均一的，可作为LAM-MC-ICPMS(激光剥蚀多接受器电感耦合等离子体质谱)的原位微区锆石~(176)Hf／~(177)Hf比值分析过程中外部校正及监控标准样。

It is found that the electric, field improves elongations in 2090 and 2090+Ce alloys markedly, especially in 2090 alloy, but has little effect on strengths. At the same time, the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation.

研究表明：固溶电场可显著提高2090合金及2090+Ce合金的延伸率，尤其是对2090合金，但对强度则无明显的影响；同时，固溶电场减少合金的沿晶分层断裂比例，并增加穿晶断裂及微区塑性变形；固溶电场还使合金时效后δ′相颗粒的平均尺寸减小、尺寸分布范围减小，并使PFZ的宽度减小。

Microminiaturization of characteristic scales makes flow behavior of polymer melt in micro-channel different from that in macro-channel, some factors, which could be neglected in macro flow, may become important roles in micro scales.

特征尺寸的微小化使得流动通道中的聚合物熔体的流动行为不同于宏观流体，宏观流动中可被忽略的因素，可能成为微尺度下的主要影响因素。
