Results The structures of the aloe leaves were basically similar as characterized by the presence of the large, well developed parenchymatous cells in the phloem pole where anthraquinones were stored. Some positive correlations exist between the contents of anthroquinones in the leaves of different species and different parts of leaves of the same species, and some phytotomic factors including the density of vascular bundles, the ratio of large parenchymatous cells in phloem and the thickness of the chlorenchyma.

结果 芦荟属植物叶的基本结构类似，维管束韧皮部内具大型薄壁细胞为该属的结构特征，是蒽醌类物质的主要贮存场所；不同种植物叶内及同种植物叶的不同部分中蒽醌类物质的含量不同与维管束分布密度、大型薄壁细胞所占比率及同化组织厚度成正相关。

In order to investigate buckling mode, buckling load and failure mode of structure, shear experiments were conducted for stiffened thin-walled composite plate. Finite element method was also used to analyze the buckling behavior of that composite structure. Analysis results reveal buckling mode and buckling loading of finite element analysis are accordable with experimental results.

通过对复合材料薄壁加筋板结构进行剪切载荷下的屈曲试验研究，得到结构的屈曲模态、屈曲失稳载荷以及破坏形式，并通过有限元方法对结构的屈曲进行数值分析，分析得到的复合材料薄壁加筋板结构的屈曲模态和试验结果一致，屈曲载荷与试验结果吻合较好。

There are many cross-section forms in this bridge style. The form of double thin-wall piers is popularly used among of them. The key problem is how to choose the thickness of one single pier and the distance between two single piers from center to center. Depending on technical experience or trial analogism, the conventional technical methods have some limitations.

在大跨径连续刚构桥桥墩截面形式中，双薄壁墩又是较常用的一种截面形式，其设计的关键问题是如何合理的选择双薄壁墩的墩中心距和壁厚，传统的技术方法是凭借经验或类比试算来决定墩中心距与壁厚，具有一定的片面性。

The results showed that fruit crispness was influenced by several factors including fruit skin thickness, thin-wall cells increasing progressively, cellulous content and fruit hardness. The relationships among those factors showed that thicker epidermal cells might mean unsuitable fruit crispness. Fruit crispness would be better if the volume of thin-wall cells very close to epidermal size increased rapidly.

对黄瓜果实脆度与组织结构和纤维素含量关系的初步研究表明，影响黄瓜脆度的因素包括果皮厚度、薄壁细胞递增情况、纤维素含量和果实硬度等，它们的基本关系表现为：表皮的厚度要适中，过厚的表皮脆度不好；近表皮的薄壁细胞由大到小递增快的，多表现为比较脆。

Based on the fundamental assumptions of thin-walled structure,bendingand torsion of monosymmetric I-section thin-walled curved beams with smalldeformation were studied in detail.

从薄壁构件的基本假设出发，对薄壁曲梁小变形时的弯曲与扭转进行了详尽的分析，首次得出了单轴对称工形截面曲梁的翘曲位移、正应力、剪应力、应力合力以及适用于各种荷载作用的控制方程的精确表达。

In explants of W5, DNA and RNA content increased in both ovules and parenchyma. DNAcontent in proligerous cells decreased after 6 days of culture. Amylose increased inparenchyma gradually and big starch grains appeared in proligerous cells.

在 W5 上的外植体内胚珠和薄壁组织细胞的 DNA、RNA 都增加，第 6-9 天，增生的细胞 DNA 含量减少；薄壁组织中多糖含量一直增加，并且发现增生的细胞内布满了大的淀粉粒。

Aim at the Non-destructive testing of thin-wall lead alloy castings, X-ray testing parameters are optimized and the hole-style image quality indicator is designed and manufactured,thus the X-ray testing and the process control of thin-wall curve face lead alloy castings are realized.

针对薄壁铅合金铸件的内部质量检测问题，通过优化射线检测参数和研制孔型象质计，实现了薄壁曲面铅合金铸件的射线检测和检测过程控制，并对在孔型象质计灵敏度控制下的渣孔类缺陷的检出能力进行了分析和试验。

The distribution of ATPase activity in the phloem parenchyma cells and flesh parenchyma cells(no-phloem parenchyma cells)changed during the different developmental phases of the fruit.It isparticularly interesting to observe a band along the plasmalemma of flesh parenchyma cellsadjacent to the phloem,the band highly enriched with the ATPase activity,forming a ring ofencirclement that surrounds the phloem.

结果表明：SE/CC复合体的ATP酶主要定位于质膜上，韧皮薄壁细胞和果肉薄壁细胞的ATP酶在不同时期的分布和活性是不一样的，令人注目的是：在邻近韧皮部的果肉库细胞的细胞壁和质膜之间发现一条ATP酶活性物质的聚集带，形成环状，包围韧皮部。
