Exist manifold types breeding materials in test field, manifest abundant germplasm resource, obviously existent prematurity type and late-maturity type . It is very difference of phenological phase, plant height, laminae area, chlorophyl content, stern diameter, seed production ,colour and shape of inflorescence and spike, yield of grass et al.

试验地引种驯化的猫尾草中存在着多种类型的育种材料，表现出丰富的种质资源，明显的存在着早熟、晚熟两种类型，这2种类型的材料在物候期、株高、叶面积、叶绿素的含量、茎杆直径、结籽性，花序及穗的颜色与形状，产草量等方面存在很大的差别。

The ideal is a self-projection; the opposite is an extension of what is; it is not the opposite at all, but a continuity of what is, perhaps somewhat modified.

理想是一种自我投射；其反面是一种真实存在的延伸；它其实不是对立的，而是真实存在的延续，或者说是真实存在在一定程度上的演变。

Most universally significance, exactly, most universally significance from the existence and life of the human beings, performance is one of the ways of human's life and existence, it is person as existent life who takes responsibility to the certain roles, that is, it is self-projection, self-presentation and then self-openness at which arrives by role-behavior and self-exhibition, as result to persuading other's trust.

从最普遍的意义上，表演是人类的基本生活方式和存在方式之一，它是作为生命存在者的人对某种角色存在的主动承担，即是通过对角色的表现和显示而实现的以使他人确信为目的的自我投射、自我呈现，并最终达成的自身敞露。

There exists a positive correlation in the analysis of the relationship between the students" proficiency test of self-explanation and academic performances in the correlation reaearch of the students" proficiency test of self-explanation and academic performances: there is a close relationship between academic performances of students and the mastery level of chemical concept study. As for the students with higher level of self-explanation,their quality of learning is higher and their academic performances are relatively better, proving that there is a close positive correlation between the academic performance of the test subjects and their self-explanation ability.

在对自我解释水平与学科成绩方面的相关性的研究中通过对被试学生的自我解释水平测试与学科成绩之间的分析发现了两者之间存在着正相关；学生的化学学科成绩与化学概念学习掌握水平之间存在着密切的关系，自我解释水平较高的学生化学概念学习质量较高，学科成绩也比较好，化学学科成绩与学生自我解释水平的存在着密切的正相关。

There is no difference between free being being as self-committal, as existence choosing its essence and absolute being.

在自由存在--------作为自我承担责任，作为选择本质的存在----------与绝对存在之间，没有什么区别。

At the same time, gene interaction was observed in some of characters, transgressive segregation gene interaction was observed in polygenes controlling length of axial root and thickness of root base （ 1cm）, complementary gene interaction was significantly detected in nodule number of lateral root and dry weight of lateral root and nodule number of lateral root, but not detected or significant in the others.

控制主根长性状的多基因间存在互作，互作方式为重叠作用；控制主根粗（3cm）性状的基因间也存在一定的重叠作用，但是作用不明显；控制其他性状的基因都存在互作，表现为互补作用，但互补作用的强弱有差异。

Major difference of gene expression occurred in the qualitative level, especially cross-fertilized kernel specifically expressed pattern.

对三个不同优势的小麦杂交种子和自交种子及其正反杂交种与其双亲种子发育前期基因表达研究表明，杂交种子和自交种子之间存在明显的基因表达差异，且以质的特异表达为主；不同优势的正反杂交当代种子与亲本间基因表达发生了显著的改变，进一步分析发现单亲表达与杂种优势存在一定的正向关系，而杂种沉默表达与杂种优势存在一定的负向关系。

In maize, the results indicated that the patterns of gene expression altered obviously in cross-fertilized kernels as compared to self-fertilized kernels, major difference of gene expression occurred in the qualitative level. Further analysis indicated that higher percentage of total differentially expressed cDNA was observed in highly heterotic hybrid than in non-heterotic hybrid.

对四个不同优势的玉米杂交和自交在种子发育前期基因表达研究表明，玉米杂交种子与自交种子在发育前期存在明显的基因表达差异，强优势的杂交组合与弱优势杂交组合之间表现差异的总cDNA比例存在极显著差异，进一步分析发现，杂交特异表达与杂种优势存在一定的正向关系。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
