It is indicated through the analysis of assistant steering mechanism of the farm transporter model fr1608 that within th e rang e of standard swinging of the pitman arm , the design rod structure satisfies the requirement of optimum pressure angle 对fr1608运输车转向助力机构的分析结果表明,在转向器转向垂臂的标准摆动范围内,设计参数满足最佳压力角要求。
The first official version of the alphabet appears in passy 1888 . these teachers based the ipa upon the romic alphabet of henry sweet 1880 - 1881 , 1971 , which was formed from the phonotypic alphabet of isaac pitman and alexander john ellis kelly 1981 国际音标最早是在1886年,由语言学家保尔巴西所带领的一群英国和法国语言教师基于教学与研究上的需要,在国际语音学协会的赞助下开发出来的,公布于1888年。
A new biased estimator so - called ridge type - generalized inverse ( rg1 ) estimator is constructed after summing - up the historical and present condition of biased estimation theory in surveying data processing . the prosperities of rg1 estimator are studied especially by pitman ' s criteria . the other biased estimator so - called partial root root ( prr ) estimator is generated 通过对有偏估计理论在测量数据处理中的应用历史和现状进行总结和分析,构造了未知参数的一种新的有偏估计方法? ?岭型广义逆估计,对其性质特别是在pitman准则下的若干性质进行了讨论;接下来构造了另一种新的有偏估计方法? ?部分根方估计,该估计的最大特点在于它是一种部分压缩估计。
The proposed method in this paper raised a way of relatively high performance recognition of pitman shorthand vocalized outline . the approach includes : a ) segmentation of the vocalized outlines , including correction of the over segmentation based on neural networks . b ) feature extraction and recognition of pitman shorthand consonant signs using neural networks 在解决这些问题的基础上,完成了本文,主要内容有: ( 1 )速记手写体的预处理; ( 2 )辅音多音节音素符笔划的二次分割法,以及基于神经网络的对过分割的检测和纠正; ( 3 )基于神经网络的pitman速记辅音符号的识别; ( 4 )基于单个符号识别结果的整体单词识别。
