最后，本文还以二元共聚树脂和三元共聚树脂为基体选择制备了三类共11个配方的玻璃布层压板。

It consists of two parts: one is for one dimension and the other is for two dimensional case.

本文研究了一类插值逼近的收敛性质，分一元及二元两部分进行。

If accuse share price in order to collect to behave reference, collect at that time accuse every to be more than 120 yuan, but drop to last week 43 yuan half, share price evaporated three, and report is filled with the share price before putting forward to be changed demesne to be n duality 7 horn half, he says: If follow constant to point to, now should drop to two-spot, with collect accuse more remnant gets a yuan.

如以汇控股价表现作参考，当时汇控每股为一百二十多元，但上周跌至四十三元半，股价蒸发了三分二，而电盈在提出私有化前的股价为二元七角半，他说："如跟恒指走，今日应跌到两元，跟汇控更剩得一元。"

Starting with the fractional viscoelastic theory, a binary mathematical model is put forward to describe the degradation rule of properties of stress relaxation and compression set of vulcanite during the thermo-oxidative aging by means of Fox-H function.

从分数阶粘弹理论出发，利用Fox-H函数提出了描述硫化胶在热氧老化时应力松弛和压缩永久变形性能变化规律的一个二元数学模型。

In 1954, Jaffe and others successfully developed PbZrO3-PbTiO3 binary system solid solution piezoelectric ceramics, which is lead zirconate titanate piezoelectric ceramics first appear.

1954年，Jaffe等人研制成功了PbZrO3-PbTiO3二元系固溶型压电陶瓷，这就是锆钛酸铅压电陶瓷最早的出现。

The catalytic system composed of NHPI and transition metal ion can catalyze effectively ethane into acetic acid,cyclane into dicarboxylic acid,toluene into benzoic acid,alkene into epoxide,alkyne into acetylenic ketone,and amide into imide;NHPI used alone can catalyze adamantane to be carbonylated,hydrogen peroxide prepared by oxidization alcohol;NHPI combined with as...

NHPI与过渡金属离子组成的催化体系能高效地催化乙烷氧化为乙酸、环烷烃氧化为二元羧酸、甲苯氧化为苯甲酸、烯烃氧化为环氧化物、炔烃氧化为炔酮、酰胺氧化为酰亚胺；NHPI单独使用能催化金刚烷发生氧化羰基化反应、催化氧化醇制取过氧化氢；NHPI与有机助催化剂如偶氮二异丁腈、溴化季铵盐、蒽醌和醇等也能催化分子氧氧化反应。

Calcium pimelate, calcium azelate and zinc azelate are prepared by alkali neutralization process, and calcium dimer are prepared using double decomposition reaction, the effect of binary carboxylate heat stabilizer on PVC thermal stability is studied adopting Congo red method and toast with heat method.

The effective permittivity for biphase organic solution at microwave frequency has been obtained by the perturbation method.

本文在微波频率下，利用微扰法测量了有机二元体系的等效介电系数。

This is a bivariant function named "Duration Intensity Function".

这就是被称为历强函数的一个二元函数。

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。
