The conversion boundary of self-incompatibility was researched by sowing by stage. Sunshine of day and temperature was studied critically by investigating leafage and researching traits indoors. The results showed that the daily minimum temperature was the principal factor of affinity conversion and the affinity conversion boundary was 16.5~18.1℃.HE97 was primarily regard as self-incompatible line in this research. The method was by inbreeding and sib HE97, Half the silk of HE97 and Zheng58. Inbreeding and cross have been done simultaneously. The extending condition of pollen tube was observed by dying the silk after pollinating 4 hours. The individuals with pollen tube were observed having seeds, while the individuals without pollen tube were observed having few seeds or no seeds. So this study regard HE97 as sporophytic self-incompatibility .The planting ration of female parent HE97 and male parent 87-1 was 4:1.The nature cross-pollination was studied by the theory of endosperm xenity, the study show that the setting percentage of HE97 was 625%, in which the seed in self was 70% and the seed in hybrid was 30%. This was consistent with the study of silk anatomy structure, then come to the same conclusion: compatible pollen germination and fertilization can stimulate the self-incompatible pollen germination and fertilization in the same corn cob.

通过分期播种，进行了光温敏自交不亲和材料HE97亲和性转换区间的研究，依据田间跟踪调查叶龄及室内考种研究了HE97亲和性转换区间的光温临界值，结果表明：1日最低温度是影响HE97自交不亲和性的主要原因，亲和性转换区间在16.5℃～18.1℃之间。2通过HE97自交和姊妹交以及将HE97与郑58作为双亲，各自的花丝一分为二，分别正反交，授粉后4个小时分别取其花丝进行固定、染色，观察花粉管的伸长情况，根据结实率与花粉管伸长的对应关系，结果发现观察到花粉管的对应植株收获到了种子，而没有观察到花粉管的对应植株结实率极低或没有结实，本研究把HE97初步划为孢子体自交不亲和类型。3以HE97为母本，87-1为父本，按4母：1父行比，通过花粉直感效应研究天然异交率，结果母本HE97结实良好(62%)，其中自交粒占70%，异交粒占30%，结合花丝切片观察表明，亲和花粉的萌发及受精会导致落在同一果穗柱头上不亲和花粉的萌发不再受抑制。

A host of studies since the mid-1990s have found common biological traits between gay men, including left-handedness and the direction of hair whorls.

The lemur, a predecessor of monkeys, had the same traits in each locale.

该基金会，前身猴子，有同样的特质在每个位置。

Based on the traits of the aspherical lens, the sunlight was focused on a very small spot, and then it was transferred into a plastic fiber by an aspherical lens and a selfoc lens. A formula for calculating the optimal length of selfoc lens is presented. The optimal assembly of the aspherical lens and selfoc lens was implemented by the aid of this formula. Therefore, sunlight is coupled into a plastic fiber efficiently.

根据非球面透镜垂轴球差小的特点把太阳光会聚到很小的光点，再利用长度约为1/4节距的自聚焦透镜改变光线的数值孔径使其满足光纤的数值孔径，通过一个计算公式来计算最佳的自聚焦透镜长度，实现非球面透镜和自聚焦透镜的最佳组合，把太阳光以较高的耦合效率耦合进塑料光纤。

Different types of vaginitis leucorrhea different traits can be used as the basis for identification.

不同类型的阴道炎白带的性状不同，可作为鉴别的依据。

They are given characteristic individual traits that make them wonderfully life-like.

他们每人都具有特有的个性，这就使他们有血有肉，栩栩如生。

The variance analysis of blood protein polymorphic loci and its performance indicates that two protein loci have a positive or negative correlation with some traits of red steppe and the improved limousin cattle population.

结论］血液蛋白多态性位点与生产性能的方差分析表明，2个蛋白位点对草原红牛及其利木赞改良牛群体的某些性状存在正相关或负相关。

These images that need no word expression and logical reasoning, even need no brain-racking search for the archetypes, are a kind of self-cultural sediment. They may have multiple and cultural relations or collisions with a declining national spirit at present, but the paintings themselves not only act as a representation of dominant cultural traits of our nation, but are also my attempts to continue stone inscriptions and brick engravings by those ancient people through knife scraping and line engraving in cold and gray tone, not only a visual sediment of my own obscure emotion, but also a kind of exterior exposition of my personal art spirit.

这些无须用言词、逻辑去表达、推理、甚至去挖空心思搜寻的形象，是自我的某种文化的积淀，或许与时下民族气性衰微与潦落的状况有着多层面的文化上的关联与冲突，但画面本身不仅成为民族强势文化特质的某种形式上的渲染，同时也希籍冷灰色调下的刀刮、线刻能够成为古人碑帖、砖刻痕迹的某种延续，既是自我内心晦涩情绪的视觉沉淀，也是个人艺术精神的某种外化的诠释。

Certainly some important traits are partly inherited, such as physical size and particular measures of intelligence, but those influence what a person doesn't do more than what he does; a five-footer will never be an NFL lineman, and a seven-footer will never be an Olympic gymnast.

当然，一些重要的特征还是部分来自于遗传的，例如身体形态和一些特异的能力，但是这些影响没有比他们自己对自己的影响大；一个五英尺高的人绝对不会成为国家足球队的前锋的，一个七英尺高的人绝对不会成为奥运体操冠军的。

These traits are most helpful in the cold, rocky mountains where the llama lives.

你可以想象一下，数百万年中，经过怎样的进化，才形成了这些特征。

You need to lie low for a while.

你们得歇手一段时间

If you do, you may just be pleasantly surprised.

如果你开口问了，或许有意想不到的惊喜。
