In this case the impressions are placed on a pitch circle diameter 120° apart; this design allows the runners to be kept to a minimum length.

在这种情况下，型腔等分120度布置在圆周上；这种设计允许流道能维持最短的长度。

From the runner balancing standpoint it is simpler by far to situate the impressions on a pitch circle diameter and feed each impression directly from the sprue via a runner rather than to incorporate a main and branch runner system.

从流道平衡的角度考虑，把型腔分布在圆周的等分点上直接从主流道通过分流道注入每个型腔的方法，远比通过一级分流道和二级分流道系统的方法简便。

optical fiber coupler, scattering matrix ; output phase difference; Hermite quadratic form ; positive definite matrix

利用其散射矩阵为酉矩阵的么正性不难证明，2×2耦合器输出相位差恒为90°，与输出功率比无关，而耦合区具有旋转对称结构的3×3耦合器的输出相位差完全取决于输出功率比，特殊地，当等分功率输出时，输出

It was Kepler in the 17th century who decided that the circle could be further divided by 5 and proceeded to create the quintile family of aspects.

在17世纪的开普勒确定了圆可以分成5等分，形成了5分的相位。

结果使用五等分分层法对临床试验中的非随机化数据进行处理，分层前两组协变量间的不均衡在分层以后达到了均衡。

For solving regular polygon,the author presents a geometrograph which divides the circumference uniformly and arbitrarily; and derives an analytic expression.

介绍任意等分圆周的几何作图法及所推导的解析表达式，提出用解三角形法解决正多边形零件在设计和加工中的计算问题。

BThese two groups of students have no significant differences in their performances on the equal-sharing concept and simple fraction concept.

2两组学童在等分概念及简单分数概念的表现上没有显著差异。

And between sexes have also shown similar differences in equal-sharing, simple fraction, units, etc.

在性别间的检定结果，分数概念、等分、简单分数、单位量概念的表现在性别间有显著差异。

There are 26 questions asking teachers to predict the correct percentages of students and they include the concept of equal dividing, simple fraction, unit of quantity and equivalent fraction.

教师预测学生答对率的试题共计26题，包括等分概念、简单分数概念、单位量概念及等值分数概念试题。

To examine the case between grades and sexes and further explore the performances of those students' fraction concepts of equal-sharing, simple fraction, units, and equivalence fraction including the intuition rules. Finally, to analyze the errors made by students' in concepts of fraction.

首先发展国小中年级学童分数概念试题，接著在年级及性别间做检定，其次探讨国小中年级学童分数概念的等分、简单分数、单位量、等值分数概念的表现及直观规律的运用，最后分析犯错误类型的学童在分数概念的表现。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
