In this paper, we mainly study the alternating group A_4 actions on spin 4-manifolds. First we discuss the special action of A_4 on K3 surfaces of Fermat type, we compute the fixed points set of this action and some invariants of the group action, also we get some topological properties. Then we study the A_4 actions on general K3 surfaces and obtain some similar results.

本文主要是以交错群A_4在K3曲面上的作用为研究对象，从Fermat型K3曲面上的特殊的A_4作用出发，得到了Fermat型K3曲面上A_4作用的不动点，利用不动点集计算了群作用的一些不变量并得到了相关的拓扑性质，在此基础上进一步把其中的一些结果推广到一般情形下的同伦K3曲面上。

In the fifth chapter in Xingjian, the employment structure and absorbing elasticity coefficient of deviation degree Angle of result is in the development process, but on the whole of the tertiary industry in Xingjian obviously higher employment contribution in the primary and secondary industries, in the future development and will continue its important role. In Xingjian, the third industry sectors in the urban employment situation analysis, the result is, in recent years the development of traditional service industry in the employment of absorbing effect decreased progressively, contribution emerging service industry has become the main force of the employment and absorb a function is to keep this trend.

在第五章，在新疆第三产业就业的分析中，从就业吸纳弹性系数和结构偏离度的角度得出的结果是，在发展过程中虽有小幅波动，但整体上新疆第三产业的就业贡献作用明显高于第一、二产业，在今后的发展中并将继续保持其重要作用；在新疆第三产业各行业的城镇就业情况分析中，得出的结果是，在最近几年的发展中传统服务行业在就业吸纳方面的贡献作用逐步减退，新兴服务行业已经成为吸纳就业的生力军，并有保持这一作用的趋势。

First, the phenomenon of the projectile-retarded mechanism of moving plates is introduced, the conditions of the projectile-retarded mechanism of moving plates is analyzed. By a number of numerical simulations, the residual length and residual velocity of the rod which penetrate the fixed plate is contrasted with those of the moving plate. Under the different velocity of moving plate, the relationship between the effect of the projectile-retarded moving plates with thickness and intersection angle of the projectile-retarded moving plates is achieved, and the most optimal thickness and intersection angle is gotten.

首先介绍了运动板抗弹作用的现象，分析了产生运动板抗弹作用的条件，利用数值计算的方法，对比了长杆侵彻固定靶板和运动靶板后长杆的剩余长度和剩余速度，分析了不同的运动板速度条件下产生运动板作用的条件，得出了运动板抗弹效果与靶板厚度和夹角的关系，得到了产生运动板抗弹作用的最优靶板厚度和夹角。

And their CD4+CD25+ Tregs in PB and MLN were much more than the model control group at the end of one or two weeks after treating with SASP and CLYSTER No. 1. Conclusion: CD4+CD25+ Tregs with strong immune suppression could play a central role in the initiation and development of mouse experiment colitis, and the CLYSTER No. 1 might exert its therapeutic effects on UC by the regulation of number and function of CD4+CD25+ Tregs.

具有较强免疫抑制作用的CD4+CD25+Tregs细胞亚群在小鼠实验性溃疡性结肠炎的发病及病情转归中可能具有重要免疫调节作用，中药灌肠1号通过调节Tregs细胞的数量对溃疡性结肠炎发挥治疗作用。

Dr Gregg Fonarow, Eliot Corday Professor of Cardiovascular Medicine at UCLA and coauthor of this study, noted, Experimental studies suggest that metformin improves myocardial function via activation of a signaling mechanism (AMP-activated protein kinase) independent of antihyperglycemic effects.

另两位合作研究者，加州大学洛杉矶分校心血管内科教授Gregg Fonarow博士和Eliot Corday博士还提到："实验室研究提示，二甲双胍改善心肌功能是通过激活了一种不同于降糖作用的信号机制（AMP-活化的蛋白激酶）"这些研究结果共同提示，二甲双胍可能具有心脏保护作用，这一作用是通过在分子水平增强心脏功能来实现的。

The optimal dose of hemostasia action of Rep

立芷雪对NIH小鼠产生最佳止血作用的剂量可能在0.58～1.74 ku/kg之间；立芷雪对新西兰兔产生最佳止血作用的剂量可能在0.21～0.63ku/kg之间，剂量达到1.90ku/kg、5.71ku/kg 具有明显的抗凝作用。

MCP could inhibit the respiration of climacteric fruits such as Starking and Fuji apple and Feicheng peach in different degree, and this effect was not be able to convert by exogenous ethylene. On the contrary, the effect of 1-MCP on the non-climacteric fruit was not ascertainment: 1-MCP inhibited the respiration of strawberry stored at 20℃ during the whole storage time, while when stored at 0℃, 1-MCP didn't inhibit the strawberry respiration.

1-MCP能够不同程度的抑制跃变型果实富士、红星苹果和肥城桃的呼吸作用，而且这种作用可以不为外源乙烯所拮抗，但对非跃变型果实草莓的呼吸作用的效果则不确定：1-MCP抑制了20℃下草莓的呼吸速率，但并没有抑制0℃下贮藏草莓的呼吸作用。

The results indicate that the spalling behavior of oxide scale is the result of the inner and outer stress together,during rolling,the oxide scale cracks under the growth stress and thermal stress,at the same time the oxide scale also mainly undergoes alternative shearing stress in the rolling zone,the oxide scale spalls,then the reason of stripspalling is also analyzed.

结果表明：氧化膜剥落过程是内外应力联合作用的结果，轧制过程中氧化膜在长大应力和热应力作用下开裂，在轧制区内氧化膜还因受沿轧辊圆周方向的交变剪切应力作用而剥落。

Then, a hypothesis of "double force source" for tectonism is put forward, its main points are: the tectonism is not only the result from the action of tectonic stress, but also the result from the action of "double force source", namely, the tectonic stress and subsurface fluid force including force produced by precipitation, etc.

提出了&双力源&构造变动假设，即构造变动不仅是构造应力作用的结果，而且是构造应力与地下流体力共同作用的结果；二者共同作用因方式不同而产生不同的构造变动；在构造变动孕育与产生过程中，构造应力的作用是第一位的，地下流体力则是调制性的，只有那些能与构造应力增强过程产生力学耦合的地下流体力，才能调制与诱发出构造变动异常并促进构造变动。

Study shows that strengthening body resistance and archaeus herbs have many effects,such as improving and adjusting immunity function,protecting bone marrow,improving haematogenesis function,raising digest and absorb function,improving substance metabolism,preventing gene mutation,inhibiting tumor cell proliferation,inducing tumor cell differentiation or apoptosis,resisting tumor invasion and metastasis,inhibiting formation of tumor vessel and activity of telomerase,etc.It's possibly the result of synergistic effect by multi-pathway and multi-target.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
