《英汉科技翻译教程》中的若干失误

英汉科技翻译除了语言技巧外 ,还要把握好相关科技背景知识。本文通过对《英汉翻译教程》中若干例句翻译的探讨 ,指出了其中的一些不当和失误 ,以求进一步提高英汉科技翻译的准确性     

机床主轴回转误差计算机辅助测试

应用计算机辅助测试（ＣＡＴ）技术，以计算机为基础，提出了一种高精度主轴回转误差在线测量方法，并开发了在线测量和数据处理系统。该系统由高精度标准球、涡流传感器、微机和数据处理软件组成。采用数字滤波方法消除一次偏心分量，在此基础上对数据处理和误差评定进行了探讨，将系统用于车床主轴回转精度的实际测量，取得了良好效果。     

数控铣削加工沟槽方法与控制

本文主要介绍在数控铣削加工沟槽时,如何利用刀具半径补偿功能,使刀具偏离工件沟槽轮廓一定距离,实现利用一个程序完成沟槽内、外轮廓粗、精加工,以及选用合适的下刀方式进行沟槽加工质量控制,并用宏指令进行编程。     

结点水准网平差及精度评定的统计功能实现

指出结点水准网等权替代法进行平差计算的理论依据为序贯平差，在分析结点水准网序贯平差特点的基础上，给出了其逐次平差和精度评定的实现步骤。剖析了计算器中固化统计功能程序的实质，扩展了其应用范围，给出了在实数权情况下各统计功能的含义，结点水准网平差统计功能实现的方法，并通过算例进行了验证。     

一种新型插齿刀的探讨

本文提出一种用曲线代替增大分度齿形角渐开线作端面齿形的新型插齿刀。该插齿刀的铲形齿形是渐开线，理论上无齿形误差，可加大前后角来改善插齿刀的切削性能，而不会对齿形精度产生影响。     

评《新时代英汉大词典》

张柏然教授主编的《新时代英汉大词典》博采众长,加上自己的创新,开辟了我国双语词典编纂的新天地。这部以计算机语料库为基础的英汉词典的主要特色在于真正做到传统与现代的交融、精确与繁丰的统一、实用与欣赏的并妍,从而保证了词典的质量。

Combination forecasting for directional accuracy: An application to survey interest rate forecasts

Using published interest rates forecasts issued by professional economists, two combination forecasts designed to improve the directional accuracy of interest rate forecasting are constructed. The first combination forecast takes a weighted average of the individual forecasters' predictions. The more successful the forecaster was in past forecasts at predicting the direction of change in interest rates, the greater is the weight given to his/her current forecast. The second combination forecast is simply the forecast issued by the forecaster who had the greatest success rate at predicting the direction of change in interest rates in previous forecasts. In cases where two or more forecasters tie for best historic directional accuracy track record, the arithmetic mean of these forecasters is used. The study finds that neither combination forecasting method performs better than coin-flipping at predicting the direction of change in interest rates. Nor does either method beat the simple arithmetic mean of the predictions of all the forecasters surveyed at predicting the direction of change in interest rates.     

《汉语拼音方案》有关标音问题的探讨

《汉语拼音方案》在标音准确性上还存在不足，主要是元音音位确立过宽和借用，音节拼字中，增、删字母等，这使得其表音变得模糊，这些标音上的问题给人们学习普通话带来了一些影响，《汉语拼音方案》的标音方法应向精细化方向改进。     

Who Are the Marital Experts?

We asked whether professional training or personal experience with marriage predicted accuracy in judging (a) marital satisfaction and (b) marital stability. Nine groups of participants viewed 3‐minute videotaped conversations of 10 married couples and rated each on level of marital satisfaction and whether they were likely to divorce in the future. Group differences were found in accuracy of marital satisfaction judgments. Those for whom marriage held high personal meaning (satisfied and dissatisfied long‐term marriages, newlyweds, recent divorcé[e]s), as rated by a panel of judges, were more accurate than those with professional training (pastoral counselors, clinical psychology graduate students, marital therapists, marital researchers). Neither professional training nor personal experience was associated with the ability to predict divorce.
