上胶

The effects of DCP content, content of in situ formed LiAA or NaAA and LiOH/AA or NaOH/AA molar ratio on the mechanical and water-swelling properties of the vulcanizates were discussed.

同时，硫化胶的力学性能和吸水膨胀性能在很大程度上取决于酸碱摩尔比，过量的AA会给硫化胶的性能带来不利的影响，但碱稍微过量（MeOH/AA摩尔配比为1.0～1.1）对硫化胶的性能影响并不大。

Scholaris and Coffea arabica (2.500 kg). Nine to eleven months after planting, A. scholaris trees grow very fast. Total biomass per plant of seed-propagated trees is 28.41kg, 3.21 times that of vegetatively propagated trees. Therefore, it is recommended that seed-propagated seedlings be used in A. scholaris production.

移栽定植后9~11个月是糖胶树生长的最快阶段；用种子进行苗木繁殖的糖胶树，其单株总生物量为28.41 kg，是营养繁殖的3.21倍，在生产上大面积推广时宜采用糖胶树种子进行幼苗繁殖。

In this dissertation, the weak gels with good thermal stability and/or salt tolerance for use in EOR were prepared from HPAM and aluminium citrate or the compound containing hydroxymethyl groups in aqueous solution. The gelation mechanisms, structure, and properties of the HPAM-AlCA and HPAM-PRIM gels were investigated. For the HPAM-AlCA gelling system, the effects of aluminium : citrate and pH value on the properties of AlCA were systematically studied.

本文以研制高性能价格比的提高石油采收率用聚合物材料为目标，在耐温抗盐水溶性聚合物研究工作的基础上，选择聚合物弱凝胶这一前沿课题为研究对象，对HPAM-柠檬酸铝凝胶的有关基础问题进行了研究，研制出了具有优异耐温抗盐性能的HPAM-PRIM弱凝胶，解决了采用聚合物提高石油采收率的高性能与低成本之间的矛盾。

Black wattle tannin was immobilized on collagen fiber by aldehydic cross-linking reaction to prepare a novel adsorbent,and its adsorption behaviors toward scandium ion(Sc3+)were investigated.

以胶原纤维为基质，通过醛交联剂将黑荆树单宁固化在胶原纤维上，制备了胶原纤维固化黑荆树单宁吸附材料并研究了IBWT对钪离子(Sc3+)的吸附特性。

Black wattle tannin was immobilized on collagen fiber by aldehydic cross-llnking reaction to prepare a novel adsorbent, and its adsorption behaviors toward scandium ion（ Sc^3＋） were investigated.

以胶原纤维为基质，通过醛交联剂将黑荆树单宁固化在胶原纤维上，制备了胶原纤维固化黑荆树单宁吸附材料并研究了IBWT对钪离子（Sc^3＋）的吸附特性。

The research displayed that yeasts Genus level can be discerned by agarose gel electrophoresis and polyacarylamide gel electrophoresis, but the latter is more advanced. The Saccharomyces cerevisiae strains ITS-1 sequences are most disalike, few of them are equal completely. The bigger differences are part of base pairs about Poly-T, others are exchanged by single base pair.

研究表明，以酵母菌株的rDNA ITS-1序列进行琼脂糖凝胶电泳，能把菌株分类鉴定到属的水平；采用非变性聚丙烯酰胺凝胶电泳能把部分酿酒酵母菌株分类鉴定到种的水平，区别效果较琼脂糖凝胶电泳有所提高；对rDNA ITS-1序列进行克隆、测序，经序列比对后发现，酿酒酵母属中酿酒酵母菌株的ITS-1序列大多数有差异，差异主要表现在ITS-1序列上游的一段Poly-T碱基上，其它处的差异仅是个别碱基的转换或颠换，ITS-1序列长度分布在360-370bp之间，G+C%含量均在35.3%左右。

The characteristics of the AP include (1) in addition to the formation of hydrogel in aqueous alkaline or polar organic solution, AP can form carbonaceous hydrogel in neutral and acidic aqueous solutions, which extents the application of carbonaceous sol-gel;(2) AP contains a large amount of nitric groups which decomposes quickly by thermal initiation, releasing a large amount of gases and heat, indicating explosive properties of the AP;(3) metal salt-containing AP is also explosible by thermal initiation, and the metal in AP promotes the explosion.

以沥青为碳源，用氧化法制备水性沥青过程中，浓硫酸和浓硝酸的比例、用量、氧化温度及氧化时间对水性沥青的收率皆有影响。经过氧化后，沥青上含有许多含氧官能团，导致水性沥青溶于水。含氧官能团越多，水性沥青越易溶于水。调节制备条件，可使水性沥青不仅可以在碱性水溶液中形成凝胶，而且可以在中性和酸性水溶液中形成溶胶、凝胶，从而拓宽了炭基溶胶—凝胶法制备炭基纳米材料的应用范围。

Since the natureal frequency of the structure can be obtained from any one of test points on it, ie. regardless of its position, the glueyness may be responded from the discrepancy of autospec-trum structure of the bicycle frame glued. For such a specified structure system,therefore, vibration monitoring which takes...

由于结构的固有频率可以从结构上任一试验点获取，即与试验点的具体位置无关，胶接车架自谱结构的差异可反映胶接质量的不同，因此，对于胶接自行车车架这一具体结构系统，以响应的自谱结构作为诊断特征的振动检测方法是简便可行的。

By use of the existing research achievements,the so-called Jiaohe River-Laihe River Strait is historically inexistent at all.
