拉丁方

In a 4×4 latin square design four steers (500±50) kg with permanent rumen and abomasum cannulae were fed on the different type of diets to study the effects of fiber digestion and VFA in the rumen on the methane production.

装有瘤胃和真胃瘘管的成年阉牛4头，体重（500±50）kg，采用4×4完全拉丁方试验设计，在呼吸代谢室内就不同日粮的纤维消化、瘤胃内VFA对甲烷产生量的影响进行了研究。

WT5BZFour adult castrated steers with permanent abomasum cannulas according to a complete 4×4 Latin square design in respiratory double chambers (BAU KB 1)were used to determine the effects of abomasal infusion with palm oil of 0,100,200,and 300 g/d on the energy conversion.

用安装真胃瘘管体重 370kg的 4头阉牛，按 4× 4完全拉丁方设计，用KB 1型自控大型呼吸测热室，研究真胃灌注不同水平棕榈油(10 0 g/d、2 0 0 g/d、30 0g/d和 0 g/d)对能量、蛋白质转化效率及血液生化指标的影响。

It focuses extensively on multiple and partial regression and correlation, some uses of Chi squares, and some advanced experimental designs and data analysis, including: two- and three- factor factorial, Latin square, nested, split-plot, confounding and fractional replication experiments.

Our result on the isotopy classes of latin squares of order 7 is also obtained by another mathematics-mechanization method.

我们用另一计算机辅助方法证明，我们所得的7阶拉丁方的564个合痕类代表元是互

So method AIC is more effective for finding the isotopy classes of latin squares.

On the basis of permutation, the concept of feature number, which is a fixed quantity of Latin square isotopy, is given.

在置换合痕的基础上，提出拉丁方合痕不变量—特征数的概念，进而提出一种判别拉丁方合痕代表元的算法—特征数法，同时提出局部合痕的概念，使拉丁方合痕代表元判别问题在实现时大大加

In this paper, we discuss symmetric Latin square s and their special orthogonality,and describe their application in the area of experimental design, together with an example of the arrangement of a kind of bridge games.

讨论的是一类具有对称性的拉丁方，并且给出这类对称拉丁方特殊的正交性的定义。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
