Vanadium mainly exists as independent minerals or in clay minerals in the form of isomorphism, with a small amount absorbed by clay minerals and limonite. Nickel mainly exists as independent minerals. Molybdenum occurs as colloidal sulfides with carbon, sulfur and clay, and forms molybdenite through thermal metamorphism. Uranium is unevenly scattered in collophanite and carbonaceous_argillaceous materials in the form of isomorphism or adsorption. REE mainly occur in collophanite in the form of isomorphism. Copper, lead and zinc chiefly exist in sulfides or sulfo_arsenides and are concentrated in the metallic layer.

钒或以独立矿物存在，或以类质同象赋存在粘土矿物中；镍主要以独立矿物存在；钼主要与碳、硫、粘土一起呈钼硫化物胶状集合体，经热接触变质作用后形成辉钼矿；铀呈不均匀分散在胶磷矿和碳泥质中，呈类质同象或吸附状态存在；稀土元素主要呈类质同存在于胶磷矿中，部分呈吸附状态存在；铜、铅、锌主要以硫化物和硫砷化物等存在，多富集在金属层中。

The key of cathode surface treatment is the component of glue liquid and the uniform degree of daubing glue, especially whether the carbon grains are transferred into diaphragm and electrolyte or not.

对负极片进行表面处理的关键是浸胶胶液配方及涂抹胶液的均匀程度，特别是负极片表面的碳颗粒是否会迁移到隔膜和电解液中。

The results indicated that the organically modifying precursors could densify the gel glass, but the thermal stability was reduced simultaneously.

结果表明，有机改性先驱体能使凝胶玻璃结构致密，但同时热稳定性降低；对于荧光性能，MTMS和VTES可使其有一定的提高，但它们的最大含量不能超过50%，否则凝胶易失透，而GPTMS能大幅提高凝胶的荧光性能。

The effect of thermal and anaerobic ageing on the structure and properties of NR vulcanizates was studied.The crosslinking density and distribution of NR vulcanizates during ageing were determined with the method of devulcanization by using the chemical probes,and the physical and dynamic properties were also determined.

研究了热空气老化和真空老化对NR硫化胶结构和性能的影响，采用化学探测剂脱硫的方法测定了老化过程中NR硫化胶交联密度及交联键分布变化的情况，同时测定了硫化胶的力学性能和动态性能随时间变化的情况。

Potassium salt of dicyclopentadienyl dicarboxylate DCPD(COOK2 was applied to CPE as crosslinking agent and a crosslinked product with 81.79% gel content was obtained in solution reaction.

以溶液反应法研究了CPE与DCPD：的交联反应，制得了凝胶量在80%以上的共价交联CPE，考察了不同牌号CPE、催化剂及其用量、反应温度、反应时间及其交联剂用量对CPE凝胶形成量的影响；通过对比实验和IR谱图证明了该凝胶确由CPE与DCPD：经双端醋化反应生成；通过反应溶解性实验验证了共价交联CPE的热可逆转化特性。

Diffluent sericin powder can be obtained from sericin solution by refining, decolourizing, degrading, concentrating and spray drying. The powder has a much better dissolvability in cold water than cocoon filament sericin.

将蚕丝脱胶后的丝胶溶液经提纯、脱色、降解、浓缩、喷雾干燥等工序，可制成易溶性丝胶粉，在冷水中溶解性良好，与茧丝丝胶有明显差异。

The castor oil based polyurethane potting materials were synthesized from castor oil,4,4 diphenylmethane diisocyanate,trimethylolpropane and 1,2 propanediol.

以蓖麻油，4，4' -二苯基甲烷二异氰酸酯、三羟甲基丙烷与 1，2 -丙二醇为原料合成了蓖麻油基聚氨酯灌封胶，研究了灌封胶的固化流变行为和凝胶化时间。

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 split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
