四分法

The reducing of samples was performed by quartering.

样本的减少为根据四分法来操作的。

Since a large particle size can easily cause division deviation, material over 10mm is not suitable for coning and quartering method. In this instance a riffle divider should be used.

由于大颗粒样品堆成圆锥时容易产生偏析，造成缩分偏差，样品粒度大于10mm不宜使用圆锥四分法，最好使用二分器。

The catalogue of ancient Chinese books experiences a historical development from sexpartite approach to quartered method,While the catalogue of collected literary works displays a path of dissociation and evolution.

中国古籍目录经历了从六分法到四分法的历史发展过程，代表中国古代文学典籍的集部目录也出现了分化演进的轨迹：从诗赋略—文翰志—文集录—集，凸显出古典文学从自发、被束缚的状态向自觉、独立发展的历史嬗变历程。

The earliest classification system written in the book Qi Lue is " one divides into six ".

七略》创立的六分法分类体系是我国最早的图书分类法；魏晋时期，一种新的分类法——四分法应运而生。

Second, based on reference research, the quartation of human capital is put forward.

其次，在文献研究基础上，本文提出了人力资本的四分法。

Coning and quartering method: put the sample onto the steel plate in the form of a cone; each scoop shall be inserted from the top of conical to make it spread along the top evenly, and pay attention not to misplace the center of cone; do it at least 3 times and mixed thoroughly; then flatten the top and use the cross plate from top to bottom to divide into 4 equal segments, randomly take out 2 oppositesegments and do it repeatedly for several times and finally divided into not less than the minimum retained quantity.

圆锥四分法：将样品置于已用样品刷好的钢板上，堆成圆锥形，每铲由圆锥顶尖落下，使其均匀地沿锥尖散落，注意勿使圆锥中心错位，如此反复至少移堆三次，使其充分混匀，然后将锥尖压平，用十字板自上插下，分成四等份，任取两个对角的等份，重复操作数次，缩分至不少于最少留样量。

The quarter system moves so fast you dont retain any knowledge.

四分法制度进度太快，记不住任何知识

During the calculation of the early age temperature field, the early age physical and mechanical performance of concrete varies with its age, therefore in the second chapter we discuss the early age physical and mechanical performance of concrete and its development regulation with time, we emphasize elastic module and the development about the early age strength of concrete varying with time, at the same time consider the effect of shrink and creep upon the early age of concrete, in succession discuss how to confirm the physical parameter of thermodynamics of concrete.

之后讨论了混凝土的热物理参数的确定。为了能够正确合理的应用有限元方法求解早期混凝土温度场问题，第三章论述了求解温度场的有限元方法。第三章首先对热传导的微分方程作了阐述。之后确定温度场的边界条件。本章采用变分原理推导有限单元法计算温度场的公式。因此在第二小节叙述了变分原理，然后阐明了不稳定温度场的计算的三种方法，确定第四章分析中将采用向后差分法求解0#箱梁早期的温度场。

15 Fourth Division: The cause mentioned in the first part of the second division is in turn divided into the famous fourfold classification of final, efficient, material and formal cause, which need no explanation.

15第四种分类：在第二种分类的第一小类中提到的原因的划分即著名的四分法：目的因、动力因、质料因和形式因，这无须赘言。

I can not make it blossom and suits me

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
