In china , traditional portal of railway tunnel can be sorted as three types - origin , modified and special types , inclusive of 16 kinds on basis of the characteristic of terrain , basically they are of end wall and post type 我国传统铁路隧道洞门根据地形特点分为基本型、变化型、和特殊型三大类十六种形式,但始终脱离不了端墙、柱式的形式。
The shoulders of human body are plotted out scientifically from the viewpoint of anatomy , the figure data of shoulders are measured by the 3d auto - anthropometric system and the design of basic style of shoulder pads are completed 按照解剖学的观点对人体肩部进行科学划分,采用三维自动人体测量系统获取人体肩部轮廓数据,并完成了垫肩基本型的设计。
3 . the development of the anther wall follows the basic type . cytokinesis in the microspore mother cell is of the successive type . the arrangement of microspore in tetrad is tetrahedral . mature pollen grain is of 2 - celled type . the anther has 4 four rooms , accidentally seen six or seven rooms 花药壁的发育为基本型,小孢子减数分裂为连续型,小孢子四分体为四面体型,成熟花粉为二细胞型。花药多为四室,偶见六室和七室。 4
The state - owned enterprise exists not only in socialist states , but also in capitalist states . this chapter also compares and analyses the state - owned enterprise ' s model and construction of the most countries in the world , which puts forward some valuable - expei ience 本章还对当代世界分国家的口有企业的基本型态、结构作用进行了比较分析,得出了一些有价值的经验教训,并对部分发达国家企业集团的一些问题与情况进行了比较分析。
Time series of discharge in neurons , that is , interspike interval ( is i ) series of action potential is considered to contain plenty of sensory information . however , there is little understanding of basic type and generating mechanism of this time coding because of the complexity of isi series 神经元放电的时间序列,即动作电位的峰峰间期( interspikeinterval , isi )序列被认为蕴含丰富的神经信息,但是由于isi序列的复杂多变,至今对这种时间编码的基本型式及其发生机制了解很少。
Our factory increase a set of intensifier with non - grade - adjustable rating speed to form the intensive air drying , the wet material mixed with hot air fully by screw feeder in the intensifier and material surface is crashed into fine granules and moving to the outlet as well as drying , under rapid rotating hitting and pushing . in the long run , the materials get a further even drying in the dryer pulled by the wind force and those wet and weighty granules the wind force can not pull continue to be crashed , dried until they are pulled by the wind force into the dryer 我厂强化型气流干燥是在基本型上增加一套转速可以无级调节的强化器组成,湿物料通过螺旋加料器进入强化器后和热气流充分混合,在飞速旋转的击刀击碎和推进下,物料被破碎成细颗粒,在干燥同时向出口移动,最后在风力吸引下进入干燥管,进一步均匀干燥,风力无法吸引的湿重颗粒继续被击碎、干燥、直至能被风吸起进入干燥管。
By using the method , 6 , 8 , 10 , 2 and 4 cam - linkage mechanisms are deduced from the 2 existing six - bar kinematic links in order to accomplish function , motion trace , trace , plane motion refer to timing and plane motion regardless of timing respectively . and 48 cam - linkage mechanisms are deduced form the 16 existing eight - bar kinematic links to accomplish plane motion refer to timing . the method is also useful in multibar kinematic links ’ transformation and helpful in developing new cam - linkage combined mechanisms 并采用此方法,对现有的2种基本型式的六杆运动链进行转换,得出6个实现函数、 8个实现运动轨迹、 6个实现轨迹、 2个实现平面运动1和4个实现平面运动2的凸轮连杆组合机构;对16种基本型式的八杆运动链进行转换,得出48个实现平面运动1的凸轮连杆组合机构。
Consequently , an open flexible ats architecture software / hardware model is established , which can meet the requirements of rocket engine ground test . on the part of the engineering application of the automatic test technology used in the rocket engine ground test , with the analysis of ats system software design methods , the universal system software of ats on windows and microsoft access is developed through virtual instrument software development tool - - labview 在火箭发动机地面试验自动测试技术工程应用方面,研究了ats系统软件设计方法,利用虚拟仪器软件开发平台labview开发了基于windows操作系统和microsoftaccess数据库的ats通用系统软件;提出了以标准配置集成方式组建基本型通用ats的思想,采用“ vxi (或pxi ) + plc ”的方案,组建了面向火箭发动机地面试验的基本型通用ats 。
