The thermal stress analysis about microscope tubes of space camera with FEA codes ANSYS is shown as an example to analyze thermal stress distribution when some thermal load affect, and the calculating results are given. 利用有限元分析软件ANSYS,以某空间相机镜筒为例,分析了在一定温度载荷作用下其温度场及应力分布,给出了相应的计算结果。
The optical microscope, electron microscope and histochemistry were used as basic techniques to study microscopic structure and submicroscopic structure of digestive tubes in 10 adult myocastor coypus. 应用光镜、电镜和组织化学技术,对10只成年海狸鼠消化管的食管、胃底、小肠和大肠壁的显微和亚显微结构进行了研究。
This paper takes Xinjiang Almond Cultivars as a researchful object. scanning electron microscope 、 style in vitro and fluorescent microscope is used to study on Pollen Morphology 、 Pollination Compatibility and the part of pollen tubes stop growing. 本试验以新疆栽培扁桃为研究对象,通过电镜扫描技术、花柱离体培养技术、荧光显微技术研究了试供扁桃品种的花粉形态、授粉亲和性和花粉管生长受阻的部位。
We observed the pollen germinated and the pollen tubes grew by Fluorescence microscope after pollination, results show that 41.02% of the pollen germinated and 3h later, pollen tubes reach ovary. 荧光显微镜下观察授粉后不同时间段内花粉的萌发和花粉管的生长情况,可以得出,羊草柱头上有41.02%的花粉萌发。在授粉3.0h后,花粉管到达子房,进行受精作用。
