By means of molecular designing, a series of sodium branched-alkyl benzene sulfonates weresynthesized through seven process, involving Frieded-Crafts reaction, Grignard reaction, sulfonationand neutralization. Those isomers have similar structure, carbons of same quantity, but the position ofalkylaryl dissimilarity. Liner fat acid, metaxylene and halogenated hydrocarbon of different carbonnumber were used as the starting materials. Optimum processing condition was confirmed consideringinfluence of a series of reaction factors such as feed proportioning, quantity of catalysts, quantitysolvent, reaction time, temperature and pressure. Eight kinds of isomers of sodium hexadecylxylolsulfonates were finally synthesized, and characterized by FT-IR.

本文在坚持马克思关于活劳动创造价值的理论基础上，对&商品价值量与劳动生产率变动规律&这一劳动价值论的重要内容作一新的创造性发展，认为关于劳动生产率与商品价值量反向运动的表述只是一种实际状态，而非全部状态，且不完全适应纵向分析；强调就一般意义上讲，个别企业、同一部门或行业和全社会的劳动生产率提高，会使商品价值总量呈现出增长趋势。

2Myocardial ultrastructure was normal in the control group,myoneme arranged disordered,the structure of typical sarcomere disappeared, mitochondrium intumesced,interstitial substance fiber hyperplasy,capillary vessel endothelial cell swelled in DG group.Myocardial ultrastructure improved slightly in rats of SM and LM groups. 3NF-κB p65 and COX-2 had a small quantity to present in the myocardium tissue of control group,while the quantity increased obviously in the diabetic group.The level of it in the group of treatment was significant lower than that in the diabetic group.There was significant difference between the two groups. Conclusion Metformin can protect against the heart injury in diabetic.

结果 1与对照组比较，DG组体重明显减轻，血糖、心脏质量指数、INS、TG、T-CH及FFA明显升高(P＜0.01)；应用 MT治疗后体重无明显增加，INS有所下降，心脏质量指数、血糖、TG及FFA明显降低(P＜0.01)；DG组心肌组织MDA明显升高，SOD明显降低(P＜0.01)，MT治疗后上述指标明显改善；2超微结构观察单纯糖尿病组肌丝结构明显紊乱，典型肌小节结构消失，线粒体肿胀、间质纤维增生，微血管内皮细胞肿胀等表现，而SM及LM组可见组织结构有所改善；3对照组心肌NF-κB p65及COX-2只有少量表达，单纯糖尿病组表达量明显增多(P＜0.01)，MT治疗后表达量明显减少(P＜0.01)。

The results show that the maximum growth quantity of Nocardia can be achieved after culturing 120 h and obvious selective adsorption of Nocardia on the surface of pyrite and sphalerite can be detected. The maximum adsorption rate on the surface of pyrite is 96.99%, whereas it is less than 20% in the case of sphalerite. Adsorption equilibrium can be attained within 20 min on the surfaces of the two minerals. pH value is the key factor influencing upon selective adsorption, and the difference of adsorption quantity on the surfaces of two minerals is apparent when pH is between 4 and 10. Slurry concentration over 6 g/L is favorable to selective adsorption. Nocardia cell concentration, stirring speed and temperature have no obviously effect on selective adsorption.

结果表明：培养120 h后诺卡氏菌达到最大生长量；诺卡氏菌在黄铁矿和闪锌矿表面发生明显的选择性吸附，在黄铁矿表面的最大吸附率可达到96.99％，而在闪锌矿表面的吸附率大都在20％以下；诺卡氏菌在两种矿物表面于20 min内即可达到吸附平衡； pH值是影响诺卡氏菌在两种矿物表面发生选择性吸附的关键因素， pH在4～10之间时，选择性吸附现象明显；矿浆浓度超过6 g/L时有利于发生选择性吸附；细胞悬浊液浓度、搅拌速度和温度对吸附效果影响不大，均可产生选择性吸附。

The shape of tunnel is gained by use of many processing ways to the initial images in the field. The quantity of overbreak and underbreak is gained by contrasting between the extracted shape and the designed shape. The same method is applied to other tunnel sections then the overbreak and underbreak quantity of a certain section or the total tunnel is gained so the problem about the evaluation of overbreak underbreak in the tunnel is solved quantitatively.

通过对野外摄取的隧洞图像进行一系列的处理得到隧洞的基本形状，然后与隧洞的设计形状对比分析，即可得到隧洞在该断面上的超欠挖方量，然后对其他断面采用同样的技术就可评价某一段或整个隧洞的超欠挖数量，这样就从定量的角度解决了以往工程中难以解决的超欠挖评价问题，为工程超欠挖的判断与决策提供合理依据。

It was different in the occurring time and quantity of dominant species: in early spring, there were more Psyllidaes in the dense planted area, but more main pests Opatrums and Scarabeidaes and their nature enemies Carabidaes and Spiders in the low planted area.
