CVA was used to study the relationship between 6 cutting heights of 3, 6, 10, 14, 18 and 24cm, and 3 population traits of herbage yield, leaf area and tiller density, on manned swards of tall rescue grown under constant light and temperature regimes. The first canonical variate, which is very significant, explained 98%of separation among the heights.

在控制光温的人工草地上，高羊茅草丛群体的3个特征-牧草产量、叶面积和分蘖密度与刈割高度(3、6、10、14、18和24cm)的关系研究中采用CVA，结果表明，第一典型相关极显著，且第一典型变量能反映刈割高度间98％的变异。

Film die where the mandrel is equipped with spider fed spiral flow channels for uniform distribution of polymer melt around entire die area. all internal die parts are hard chromed with high polish. easy adjustable die opening for accurate film thickness control.

模头心轴处安装了蛛网供料螺旋导流槽使聚合物熔体在整个模头区域得到均匀一致的分布，所有的模头内部部件均镀硬铬并高度抛光；易于调整的模头开口容易获得准确的薄膜厚度控制。

The model not only provides a fast means of modeling transients in gain-clamped EDFA′s, but also shows clearly how the laser relaxation oscillation frequency, damping constant, and oscillation amplitude are affected by design parameters through explicit analytical expressions. Modeling shows quantitative agreement with experiments when the spectral-hole burning effect plays minor role on EDFA transients.

首次发现全光链路控制EDFA瞬态的WDM系统中，通过环形腔激光反馈产生的补偿信号，在系统要求的典型功率范围内就可能发生受激布里渊散射，并因此损伤系统性能。

There are many factors to influence the accuracy of laser alignment and target position.

本论文正是针对上述因素，在神光II升级项目靶场分系统的设计中，通过对靶场中关键元器件的优化设计，以提高焦斑性能和激光弹着点控制精度，使其满足系统设计的要求，为项目的顺利实施提供必要的设计参考数据。

"Titanium Goose Ceramic High Speed Rail under the ceramic production 'K2O-Al2O3-SiO2′ ternary system phase diagram and the iron titanium oxide in different color under the conditions of the principle of green glaze recipe for technological innovation so that billet, at the end of the glaze, glaze surface three raw materials as close as possible to the expansion coefficient, at a high temperature reduction firing, the control FeO/Fe2O3 proportion and coloring oxides of different valence state to develop a cream-colored,棕红, brown, light窑变blue color, and simplicity of natural color, green color and窑变color white, color, soft, short thick matching, contour lines of fresh, rich European-style."

A necessary and sufficient condition for the curve being torsion curve in every sub-interval is given.

当张力参数趋于零或趋于无穷大时的极限曲线，分别是等距节点的有理三次B样条曲线和其控制多边形，故张力参数可用于调节曲线的光顺性。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
