Videlicet, this sequence represents the accountability of the 11 features in distinguishing insects on the level of species. According to the above results, some features varies not remarkably on all levels, such as Lobation, Shape-Parameter etc. This shows that such kind of features are nearly same in all species of insects, and can represent the feature suitable to distinguish all insects from other classes of animals. On the other hand, they are not suitable as distinguishable features of levels which lower than insect Class.

从结果可以看出，有些特征在各个分类阶元上差异均不是很显著，如叶状性、形状参数，说明此类特征在昆虫中具有较强的共性，可以代表整体昆虫的特征，而不适合于作昆虫纲下阶元的分类特征；有些特征在各分类阶元下的差异始终比较显著，如周长、面积等，说明这些特征适合在各分类阶元上作为昆虫的分类特征。

As a result of analysis to many of the results of experiment, checked up on specimens, field investigation and combining with the theories of palaeobotany, comparative morphology, evolutional morphology of vascular plants and taxonomy, it can be concluded as following: the primitive sorts of Cycadaceae are the sorts that pinnate leafs are dichotomy; among these, the sort that pinnate leafs are tripinnate-dichotomy is most primitive, from this sort gradually evolve to bipinnate-dichotomy, to only for monopinnate-dichotomy, from this sort evolve to the sorts that pinnate leafs are simply pinna; among the sorts of simply pinna, the species that segments of megasporophyll possess much more triplicate to monodichotomy are most primitive.

经过大量的实验结果分析、查阅标本和野外调查，结合古植物学、比较形态学、演化植物学和分类学等理论进行分析，认为苏铁科原始的类型为羽叶呈二歧状分叉的种类，其中最原始的又是羽叶呈三回二歧状分叉的种类，从这个羽叶类型逐渐演化出一回二歧状分叉的羽叶类型，再演化出羽叶为单羽状的类型；而单羽状叶的类群中，又以大孢子叶侧裂片具三回、二回及一回二歧状分叉数量多的种类为最原始，而侧裂片二歧状分叉数量少的为较进化，侧裂片无二歧分叉的如拳叶苏铁类为最进化的种类。

Correlation analysis showed that meteorological variables, such as containing water rate of sandland, photosynthetic available radiation, air temperature, saturated water vapour pressure difference, and physiological variables, such as leaf area index, leaf temperature, stomatal conductance, affected transpiration of S.

相关分析结果表明，环境因子，如沙地含水率、太阳有效辐射、大气温度和饱和水汽压差，以及植物因素，如叶面积指数、叶片温度和气孔导度等，均能显著影响沙柳的蒸腾作用。

Ferns do not show secondary thickening, but in large ferns such as tree fens bands of sclerenchyma and the overlapping bases of the fronds help to support the plant.

真蕨类无次生加厚作用，但在大型真蕨中如树蕨具有厚壁组织，叶的重叠也有助于支撑植物体。

A joint between two separable parts, as a leaf and a stem.

节植物两个可分部分的连接，如叶与茎连接处

Having three leaflets, as a leaf of clover or string bean.

具三叶的有三中叶的，如三叶草或豆类植物的叶子

Having three leaves or leaflike parts, as in the trillium.

三叶的有三片叶子或具三个叶状部分的，如延龄草

Pinnately compound with a single terminal leaflet, as in the leaves of the rose plant.

奇数羽状叶的与顶端羽状单叶接合的，如蔷薇科植物的叶

Hepatophyta (marchantiopsida; liverworts) A phylum containing leafy and prostrate thallose forms, commonly known as liverworts, Thallose liverworts are prostrate and dichotomously branched with thalli several cells thick.

苔类植物门：是一门包括多叶的或匍匐叶状体类型的植物，如通常所说的苔类。

"We are your guests, but there is no difference between us and pigs because you treat us like pigs, eating the leaves of sweet potatoes.""Didn't you tell us you would offer boiled sweet potato leaves?"

&我们是你们的客人，却和猪没什麼两样，因为你们视我们如猪一样的招待吃地瓜叶&，&你们不是说，要煮地瓜叶的吗？&

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
