The effects of solid content of latex, reaction temperature, the amount of phenylhydrazine and pepegal O on the viscosity-average relative molecular mass M(subscript n of LNR were investigated, and the optimization of these influence factors was conducted by orthogonal test.

以天然橡胶浓缩胶乳为原料，在热氧条件下采用苯肼为催化剂通过化学降解法制备液体天然橡胶，考察了胶乳的总固物质量分数、反应温度、稳定剂平平加O和苯肼用量对LNR黏均相对分子质量M(下标 n的影响，并通过正交实验进行优化。

The pseudopodial movement could be inhibited by calcitonin (100 μg*L－1). Lacuna formation could be found in cocultured specimens. There were fibrils on the walls of lacunae. The MGCs demonstrated positive reaction with Gomori stain. Conclusion: The results demonstrated that MGCs had the same morphological features and the bone resorption ability as the osteoclasts.

结果：倒置相差显微镜下可见多核巨细胞胞核较多（20个以上），胞浆周边不规则，有伪足样突起；胞浆内可见较多大小不等的空泡；降钙素（100 μg*L－1）可抑制多核巨细胞的伪足样运动；多核巨细胞与灭活的骨片共同培养时可见骨吸收陷窝形成，扫描电镜下可见吸收陷窝底面有原纤维；Gomori染色时可见多核巨细胞的酸性磷酸酶呈阳性。

The results show: in a specific concentration range, the solubility in neutral solution of SOL, as well as the surfactivity, the ability to reduce ITF and the wettability on the condition of non- alkali are better than the lignosulfonate in market.While using as sacrifice agent, the modified lignosulfonate can reduce 60% of the mahogany sulfonate and 50% of the α-alkene sulphonate which both are adsorbed on the oil sand surface.

结果表明在一定浓度范围内，SOL在中性溶液条件下的溶解性、在无碱条件下的表面活性、降界面张力能力、对岩石的润湿性效果优于市场木质素磺酸盐产品；作为牺牲剂使用时，改性磺化木质素能减少石油磺酸盐在油砂表面吸附的60%，减少α-烯烃磺酸盐在油砂表面上吸附的50%。

Even if a bleached zone contains live polyps and carries the potential to recover when waters cool, a quick invasion of kelp, or types of algae that do not live symbiotically with coral, can make the die-off permanent - hence the protective role of plant-munchng fish.

即使白化区仍有活著的珊瑚虫，当水温降了下来时还是有复原的机会，而巨藻或其它几类无法与珊瑚共生的海藻的快速入侵下，致使珊瑚相继死绝-由此可知这些大啖植物的鱼类，它们的保护作用。

Analysis result shows that the dynamic interaction between wheel and rail and the rail-pad force of the strengthened track are little bigger than those of the unstrengthened track,the safety grades of the tracks are same,the strengthened track can benefit to decrease the displacements of all components of track structure obviously,to restrain the deformation of track effectively,and to reinforce the stability of railway,especially the lateral displacement and the gauge enlargement of the strengthened rail are about 33% of original rail.

分析结果表明：强化后轨道结构的轮轨动态相互作用力及轨枕支点压力均较强化前的相应值略大，但皆属相同安全合格等级；强化轨道结构位移大幅度降低，有效抑制轨道结构变形，增强线路稳定性，尤其是钢轨横向位移和轨距动态扩大量较强化前下降十分显著，前者仅约为后者的1/3左右；强化轨道也有利于降低轨下结构振动和减轻列车提速后对轨下基础的破坏。

In Trollveggen, an even more dramatic drop in the middle of the country, you may plummet for a long half minute, allowing time for backflips, somersaults, or hurtling side by side with a friend.

In control, however,the weak expression ofCY3 mRNA can be found after 48 hours of chilling and showed little increase at the third day instress.

非逆境条件下，IPT对秧苗根系中mRNA的表达差异与对照相比没有很大的变化；低温胁迫3天后，IPT对根系中mRNA的表达影响很大，既能增强某些基因的表达，又能抑制另一些基因的表达；用DDRT-PCR技术，寻找到5个低温胁迫下在对照和IPT处理中差异表达的基因，其中CY3片段与水稻CDPK1和CDPK2的mRNA有很高的同源性，初步断定CY3在植株的抗逆反应中可能具有与CDPKs相似的功能；在Genbank中没有检索到与其它4个片段同源性比较高的已知序列；IPT处理中CY3表达量在低温处理24hr就有明显升高，以后随胁迫时间的延长其表达量不断加强；恢复常温后，CY3表达继续增加，在恢复第14天开始下降，下降速度缓慢，IPT对CY3的影响一直延续到苗末期，对照中CY3在低温胁迫48hr才有微弱表达，72hr后表达量并未增加许多；恢复常温后第4天就开始下降，很快降到最低。

The research used microwave power 600W,and S/L is 1/10, with the suitable microwave operation condition (nitric acid concentration 9.0 mole/L, digesting time 8 minute, and digesting temperature 140 ℃), by microwave digestion lead leaching rate is 94.11%, if it used microwave power 600W,and S/L is 1/10, with the best microwave operation condition (nitric acid concentration 0.8 mole/L, digesting time 6 minute, and digesting temperature 120 ℃), by the result of study, after Microwave Digestion Treatment, the TCLP leachate of lead in reaction ash might could be reduce to 4.83 mg/L from 7.10 mg/L, and the TCLP leachate could keep under the regulation control standards.

本研究以微波功率600W、固液比1/10，在最适微波条件下(硝酸浓度9.0M、消化时间8分钟、消化温度140℃)，铅的微波消化溶出率为94.11％。在微波功率600W、固液比1/10，以微波最佳条件(硝酸浓度0.8M、消化温度120℃、消化时间6分钟)，经微波消化处理后，其铅TCLP 溶出量由7.10 mg/L降为4.83 mg/L，已能符合法规管制标准值。在此最佳微波条件下，对於铅TCLP 削
