查询词典 substituting

Efforts to simplify the cladding process by substituting a glassless braze-HIP cycle for the glass-HIP diffusion bonding cycle were not successful due to the inability to insure 100% leak-tight brazed seams.

为了简化程序，以覆面的刹车glassless-Hip周期为玻璃胯扩散焊接周期没有成功，因为无法保证100%漏风雨焊缝。

From the structural analysis of three praseodymium complexes, we could draw a conclusion that as the dentate arms of carboxyl group on ligands elongating, the coordination numbers of Pr and the coordination modes of ligands increase, and the mean distances between metallic atoms of metallic helices existing in these complexes augment.2. By altering 5-substituting group of isophthalic acid three series of lanthanide complexes 8～19 with 5-methylisophthalic acid and 5-nitroisophthalic acid have been prepared.

从得到的三个配体的镨配合物的结构分析可以看出，随配体的羧基齿臂的增长，Pr的配位数逐渐增大，配体的配位模式增多，配合物中存在的螺旋金属链中的金属间平均距离增大。2、通过改变间苯二甲酸配体的5位取代基，制备了5-甲基间苯二甲酸和5-硝基间苯二甲酸的三个系列稀土羧酸配合物8～19。

In complexes 8～16 synthesized by hydrothermal method, most of the ligands adopt multidentate coordination modes joining several lanthanide ions into high-dimensional coordination polymers. And changing of 5-substituting group on isophthalic acid has a little effect on the coordinated abilities of the meta-carboxyl groups.

水热法制备的配合物8～16中，配体多采取多齿配位模式桥连多个稀土离子，形成高维配位聚合物，同时由于羧基氧原子和稀土离子的强的键合力，间苯二甲酸的5位取代基的变化对间位羧基的配位能力的影响不大。

The work proved the possibility of substituting inorganic acid with strong acidic resins for levulinic acid preparation from biomass.

该研究结果证实了用耐水型强酸性树脂替代现有的无机酸催化制备乙酰丙酸的可能性。

As a developing country, there still have 30 years to stop the production and distribution of R 22 in China , and there are very few technical obstacles in substituting C22 for R 410A . But the substitution will follow with the higher costs of production. And because of the threat of 揼 lobal warming? the future of R 410A is still unclear. How can the air-conditioner industry deal with this problem?

作为发展中国家，中国距最终禁止 R22 的生产与销售还有 30 余年，虽然目前进行绿色制冷剂的替代在技术上的障碍并不多，但随之而来的却是空调生产成本的提高，而且面对着全球变暖的问题， R 410A 等绿色制冷剂的前景还并不明朗，那么在这个问题上，空调行业将走向何方？

Among them, BRS1 with mercapto alkylchlorine substituting group, which can be used as intermediate for the synthesisof new BR derivatives.

其中一种(BRS1)为末端氯代的化合物，可以作为中间体用于进一步的合成中。

In this new technology,on the basis of substituting flotation froth of high intensity scavenger concentrate for high intensity middlings,the desired RE concentrate can be obtained easily,which does not take any special measures of removing surplus reagents and adopts the current technological process taken by workshop of RE ore dressing,and the cost of flotation reagents per ton RE concentrate can also be reduced about 50%.

将生产中所用的稀土浮选原料强磁中矿更换为强磁扫选精矿的反浮泡沫，不需特别的脱药措施，只采用稀选车间现有的工艺流程和浮选药剂组合方案，即可获得所需的稀土精矿，使每吨稀土精矿的成本降低一半左右。

Considering the disadvantages of the elemental iron-based matrix, a partial alloyed Fe-Ni-Cu-C powder and an iron-based monophase fcc structure alloy were used for substituting the cobalt, and the experimental results were encouraging.
