To elucidate the biological structure basis of transgenic rice plants expressing maize PEPC gene with high photosynthesis efficiency, PEPC transgenic rice and its wild type with at 3 leaves seedling stage were treated under 1000 μmol/(m^2s) light intensity for 100 min, respectively, and those under 200 μmol/(m^2s) light as the control. The structure of mesophyll cells, bundle sheath and thylakoids of the second blade were observed with a transmission electron microscope.

Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L 2, 4-D 2.5 mg/L, and 300 mg/L CH 0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus.

结果对仙茅叶片的愈伤诱导，黑暗的效果好于光照；在所试验的培养基成分中，适宜的激素配比是2.0mg/L2，4-D或6-BA1.5mg/L 2，4-D2.5mg/L，并且附加300mg/L水解酪蛋白和0.2%活性炭，对于仙茅叶片的离体成苗较好；培养后，愈伤组织主要由叶片的中脉产生，位于中脉上表皮内侧的薄壁细胞首先启动分裂，随后维管束鞘薄壁细胞及其外侧的叶肉细胞也启动分裂，参与愈伤组织的形成。

From the point of microstruction,bamboo volume fraction of bundlesheath,single bundle sheath area,fiber width,cell wall thickness increase withthe growth of age,fraction of cell wall changes like density,increases with thegrowth of age,the 2 age-degree bamboo is the biggest.The reason why 2 age-degree fraction of cell wall more than 3 age-degree bamboo is the former has thegreater fraction of parenchyma;1 age-degree bamboo has the greatest fiberlength,fiber length and width ratio and vessel length.The difference in bamboofiber length,vessel length and width among other age-degrees is not distinct.

从构造角度来说，竹材的纤维束比量、单个维管束纤维束面积、纤维宽度、胞壁厚度随着年龄的增大而增大，胞壁率随年龄变化规律与密度相似，随年龄增大而增大，以2度竹最大，2度竹胞壁率比3度竹大主要由于薄壁组织比量较大所致；纤维长度、纤维长宽比、导管长度以1度竹最大，其它年龄纤维长度、导管形态变化不明显。

Through comprehensive comparison,during the growth from 1 age-degree bamboo to 2 age-degree bamboo,density, mechanical strength(except maximum tensile strength etc.),fraction of bundle sheath,cell wall ratio,crystallinity,cellulose content and lignin content increase rate are the greatest.3age-degree bamboo has higher strength,strength and gravity ratio andcrystallinity are the biggest,fraction of parenchyma is small and insect-resistant.2 degree bamboo has the greatest mechanical strength,but its strength andgravity ratio is not the highest and its crystallinity is lower than 3 age-degreebamboo due to its greatest fraction of parenchyma,loss tangent value is thebiggest.Its creep character is not good and is easily eaten by moth.

通过综合比较，竹材从1度竹到2度竹生长过程中，密度、力学强度、纤维束比量、胞壁率、结晶度、纤维素含量、木质素含量等指标增加幅度是最大的。3度竹强度较高，强重比、结晶度最高，薄壁组织含量较小，相对抗虫蛀，材质最好，适合材用。4度竹结晶度下降引起强度的下降，但薄壁组织组织比量最小，相对最抗虫蛀。2度竹力学强度最大，但是强重比并不是最大，结晶度比3度竹低，由于薄壁组织组织比量最大，内耗值最大，蠕变性能较差，同时相对易遭虫蛀。

A universal card with multi-purpose refers to a card that can be used in both of card brushing reader and optical driving to fetch data. It is mainly made as to set a CD fetching face and a magnetic strip on the disc (thickenss of 0.8 mm) being produced in accordance with ISO 7816 agreement rules to fetch the data stored in the magnetic strip or IC card by inserting them to a card brushing machine or a card inserting machine. The disc also can be placed on the fetching sheath disc of 0.4 mm thickness and further to place them together into an optical driving firmly for reading out data on CD fetching face by optical fetching head in optical driving so that it is not only integrating magnetic card, IC card and CD disc for easy to carry but also increasing the safety in using, storing volume of the disc and expanding the using range.

本发明涉及一种多用途万用卡，尤指一种可同时适用在刷卡卡片阅读机及光驱内进行数据读取的多用途万用卡，其主要是在一符合ISO 7816协议规范(厚度0.8mm)的盘片上设有一CD读取面及一磁条，可插入一刷卡机或一插卡机内读取磁条或IC芯片内的储存数据，而该盘片又可放置在一厚度为0.4mm的读取套盘上，致使当该盘片放置在读取套盘后可安稳放置在一光驱内，且方便光驱内的光学读取头读取CD读取面内的数据，因此不仅可整合一磁卡、IC卡、CD片等于一盘片中以方便携带，又可提高盘片使用的安全机制、内存容量及扩展其使用范围。

Since chain conveyer is let , expects , is even , is steady with traversal speed, the power change that consumed in working process is not large , thus the power of actuating device less prick Jia Lu suddenly make noise signboard sheath Lu earth the structure of chain is ever changing, so chain conveyer can apply to numerous use environment and numerous use ask .

由于链条输送机供料均匀与运行速度稳定，工作过程中消耗的功率变化不大，因而驱动装置功率较小链条输送机的重要功能元件是输送链，而链条的结构是千变万化的，所以链条输送机能适用于众多的使用环境和众多的使用要求。
