OBJECTIVE To investigate the significance of expression of p53, Mdm2 and p21(superscript WAF/CIP1) proteins and their relationships.

目的 探讨p53、鼠双微体2(murine donble minute 2， Mdm2)及p21(上标 WAF/CIP1)等蛋白在甲状腺癌组织中的表达、意义及相互作用关系。

RESULTS The positive expression rate of p53, Mdm2 and p21(superscript WAF/CIP1) in thyroid carcinoma was 50.6%(37/73), 63.0%(47173) and 38.4%(28173) respectively.

结果 p53、Mdm2及p21(上标 WAF/CIP1)在甲状腺癌中表达的阳性率分别为50.6%(37/73)，63.0%(47/73)和38.4%(28173)。

I am no more lonely than the Millbrook, or a weathercock, or the north star, or the south wind, or an April shower, or a January thaw, or the first spider in a new house

比起牧场上的一朵毛蕊花，一支蒲公英，一片豆叶，一束酢浆草，一只牛虻或大黄蜂来，我并不孤单多少；比想密尔溪，风标，北极星，南风，四月春雨，正月融雪，或者新房中的第一只蜘蛛，我也并不更加孤单。

If Whittier and Intel have their way, they will be inside, well, everything.

如果怀特和英特尔继续在他们的道路上驰骋，他们将会将英特尔植入所有的东西，他们的一个品牌将会覆盖所有的东西，不论是智能手机、还是车载电脑、以及各种价位的家用电脑，还有大众办公系统，像是兔子一样，人们将会看到奔腾芯片的大爆发，这些芯片将遍及每一件产品，从低价位到高价位产品，远远超过了英特尔标志在1991年首次推出内置英特尔标志时候所想象的那样。

The Mn(superscript 2+)-BrO(superscript - subscript 3)-H(superscript +)-Act oscillating systems of Chinese traditional medicine compounds (Siwu Decoction and Windflower Decoction) are studied at different concentrations and different temperatures by TAM Air 8-channel calorimeter.

用微量量热法对中药复方四物汤和白头翁汤的Mn(上标 2+)-BrO3-H-Act振荡体系进行了研究，得到了四物汤和白头翁汤分别在不同浓度、不同温度下的振荡谱图和310K时体系发生振荡的浓度范围。

The winter-time PM2.5 pollution was serious with an average concentration of 223μg/m^3. Organic matter, sulfate and elemental carbon were the most abundant species constituting about 23.4%, 13.1% and 12.8% of the total PM2.5 mass, respectively.

结果表明，天津冬季PM2.5污染严重，平均质量浓度为223μg/立方公尺，其中有机物、SO4(上标 2-)和元素碳是含量较高的3种组分，分别占PM2.5总质量的23.4%，13.1%，12.8%。

YAG/CO2 laser marking machine can be fine in metal, leather, wood, two-color panels, plexiglass, crystal, such as different materials on a variety of text and logo engraving, sculpture has a certain depth is not easy indelible and very beautiful, with wire Network printing can not mark the effect.

YAG/CO2激光打标机能够精细地在金属、皮革、木材、双色板、有机玻璃、水晶等不同材料上雕刻各种文字和图案，雕刻具有一定的深度不易磨灭，而且非常美观，具备丝网印刷达不到的标记效果。

Maleic rosin has been added to the surface of wood flour in the form of monoester, i.e., the formation of esterified wood flour bearing a pendent carboxylic group. The rheological study showed that the complex viscosity η(superscript *, storage modulus and loss modulus of WF-HDPE composites decreased firstly and increased afterward and declined lastly as the dosage of maleic rosin increased, however, the viscosity of the composite melts decreased as a whole. After the modification of wood flour, the rheological properties of composite melts were improved markedly. According to the mechanical test it was indicated that, by proper treatment of wood flour with maleic rosin, the tensile strength and flexural strength of WF-HDPE increased obviously.

WF-HDPE流变学研究表明：复合材料的复合黏度η(上标*、储能模量和损耗模量随马来松香用量的增加先减小后增大最后减小，但体系的黏度和模量总体呈下降趋势，木粉经马来松香改性后复合熔体的流变性能显著改善，这不仅有利于提高复合材料的成型加工效率，而且适当的马来松香处理也能够提高复合材料的拉伸强度和弯曲强度，后者被静态力学试验结果所证实。

In the third area, Pb2 is gradually supersaturated in solution with the increase of pH value, so the Pb2 is deposited as sediment. As a result, the processing of wulfenite leaching by sodium hydroxide is carried out. Additionally, feasibility of the processing of wulfenite leaching by sodium hydroxide is proved, but Pb(superscript 2+) reacts with hydroxyl to form complexes which is leached into solutions. So removing the complexes lead from solution is needed.

通过对Pb-Mo-H2O系的热力学分析，苛性钠分解彩钼铅矿在一定的pH值下是可行的，但在碱分解过程中Pb(上标 2+)与羟基形成了配合物，主要是以Pb3的形式存在而大量进入溶液，因此，尚需进一步除铅。
