查询词典 first-order theory

Time are tested under different kinds of stress for nitrided and un-nitrided specimens made from 35CrMo steel. The testing time ranges from 70 to 80 hours. The following equations are regressed from the tested curves: Un-nitrided specimens:〓 Nitrided specimens:〓 The above equations are consistent with the first stage theory for creep.

为此本文通过实验，测试了35CrMo钢渗氮和未渗氮两种试样在500℃时不同应力情况下的应变随时间的变化曲线，实验时间为70-80小时，将测得的曲线回归出以下方程：未渗氮样品：〓渗氮样品：〓以上方程符合蠕变的第一阶段陈化理论公式。

For the first time, we combined ultrasonic wave and time domain reflectometry to study the relationship between gas hydrate saturation and acoustic parameters in the process of gas hydrate formation and dissociation, and got fine results.

本文首次利用超声和时域反射联合探测技术，研究了沉积物中水合物饱和度与声学特性的关系，并对时间平均方程、伍德及其修正方程、李权重方程和BGTL（Biot-Gassmann Theory by Lee）理论等常用的水合物饱和度估算模型进行了验证。

Company insists on" quality for first" management theory that " based on sincerity ", and it makes great efforts to set a situation of to-win together with many sandblast enterprise!

We first denoise the SAR image by Lee filter.Next,the maximum likelihood classifier based on different distribution was used for SAR and SPOT images(Based on Wishart distribution and multivariate Gaussian distribution respectively),to extract the conditional probability of each pixel for each class.

首先使用李式滤波器滤除全偏极雷达数据噪声，接下来同样是使用采用最大似然法来分类融合影像，(不同的在于全偏极雷达影像使用Wishart几率分布，在光学影像采用multivariate Gaussian几率分布)将每个类别中每个像元属于某个类别的几率值计算出来，再利用Dempster-Shafer evidence theory来结合这些类别的机率值。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
