The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.

研究指出，水洗工艺所得ZrO〓-Y〓O〓粉末几乎完全由硬团聚组成；乙醇洗涤工艺的脱水效果不是很好，并且由于乙醇的沸点比水低，以致在干燥过程中残留乙醇比水先挥发，乙醇的空间位阻效应不能有效地发挥作用，因此，仍然可以导致产生一定量的硬团聚；而共沸蒸馏工艺的脱水效果最佳，且正丁醇的沸点比水高，干燥时残留正丁醇比水后挥发，从而正丁醇的空间位阻效应可有效地发挥作用，因此避免了在煅烧过程中形成Zr-O-Zr键，即共沸蒸馏粉末中不含硬团聚。

Firstly, A precise batch-distilling tower, which would be adaptable to operate in industry or middle scale experiment, has been designed and set up. The optimized operation conditions of reflux (80?1), vaporing quantity ( 9~10 mL?min-1), and raw material concentration (60% mass of 2-methyl-1-butanol) were found.

首先在小试研究成果的基础上，放大设计并建造了适合2-甲基-1-丁醇与3-甲基-1-丁醇的分离的中试或小规模工业化生产的间歇精馏装置，并以此装置作为实验装置进行了工业化试验，得到了该塔的最优操作条件：回流比80、汽化量9~10ml/min、原料中2-甲基-1-丁醇的质量百分浓度约为60%。

Irony penetrates all strata of Austen"s novels, the narrative language, characters, scenes, motifs and structural design. Irony is not just a primary artistic maneuver of Austen"s novels, but also a framework in which Austen apperceives the world.

反讽渗透于奥斯丁小说的每一个层面，从语言、人物、场景到更深层的主题和构思，它不仅成为奥斯丁作品的一种主要艺术手段，而且还成为奥斯丁领悟世界的一种方式。

However, Martin Luther King''s image, as a peaceful leader of the American disfranchised, lives on; Martin Luther King''s voice of dream of achieving equality and tolerance lives on; Martin Luther King''s ideal and spirit that one day people from around the world would be able to walk together as brothers and sisters---lives on.

但是，马丁·路德·金的形象，一个美国受压迫者的形象，仍然流连在我们中间。马丁·路德·金声音，一个高喊着种族平等和宽容的声音，仍然回旋在我们的耳际。马丁·路德·金的理想和精神，一种梦想---总会有那么一天，来自世界各国各民族人民能象兄弟姐妹一样携手漫步---仍然萦绕着我们的思绪

When there were two kinds of active sites with different properties, isobutene were formed on one kind of active site, and then, spilled over to the other active sites, reacting to MAL, isobutene forming as the final product was restrained, and the oxygenates yield was increased.

当催化剂表面存在相邻的两种化学性质不同活性位时，异丁烷在一种活性位上生成异丁烯后，异丁烯可能在催化剂表面迁移到另一种活性位上，继续反应生成甲基丙烯醛或甲基丙烯酸，这抑制了异丁烯作为产物从反应器中流出，并提高含氧有机物收率。

A novel method combining a conventional free-radical solution polymerization with a chemical saponification was used to synthesize a, cu-dicarboxyl terminated oligo s with molecular weight below 1500. Here, cn-carboxyl terminated oligo s were firstly synthesized by the free-radical polymerization in THF, where 4,4'-azobis(4-cyanovaleric acid) was used as initiator, thioglycolic acid as chain transfer agent, then CTBMA were transformed into di-CTBMA via saponifying CTBMA in dioxane/H_2O/KOH solution.

A four-ball tester was used to evaluate the load carrying and antiwear properties of bismuth dibutyldithiocarbamate,bis-dibutyldithiocarbamates(V7723),sulfurized isobutylene,molybdenum ester non sulfur and phosphorus in a mineral oil respectively and their synergistic effects.

利用四球试验机评价了二丁基二硫代氨基甲酸铋与二丁基二硫代氨基甲酸酯(V7723)、硫化异丁烯和非硫磷钼酸酯添加剂的极压和抗磨性能，以及它们之间的极压和抗磨协同作用。

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。
