A new method and instrument for accurately measuring interval between ultrashort pulses

Using second-order autocorrelation conception, a novel method and instrument for accurately measuring interval between two linearly polarized ultrashort pulses with real time were presented. The experiment demonstrated that the measuring method and instrument were simple and accurate (the measurement error <5 fs). During measuring, there was no moving element resulting in dynamic measurement error.

Effects of rhFSH regimen and time interval on ovarian responses to repeated stimulation cycles in rhesus monkeys during a physiologic breeding season

We studied the effects of repeated stimulation by recombinant human FSH (rhFSH) at various time intervals during a physiologic breeding season in rhesus monkeys. Ovarian recovery and responses were assessed by ultrasonography, serum steroid concentrations

Birth seasonality and interbirth interval of captive Rhinopithecus bieti

This study, which is based on 10 years of birth records, shows that black-and-white snub-nosed monkeys (Rhinopithecus bieti) in captivity display marked birth seasonality. The birth season starts in December and ends in June, with a peak from March to May

Measurement of gain spectrum for semiconductor lasers utilizing integrations of product of emission spectrum and a phase function over one mode interval

A technique based on the integrations of the product of amplified spontaneous emission spectrum and a phase function over one mode interval is proposed for measuring gain spectrum for Fabry-Perot semiconductor lasers, and a gain correction factor related to the response function of the optical spectrum analyzer (OSA) is obtained for improving the accuracy of measured gain spectrum. The gain spectra with a difference less than 1.3 cm(-1) from 1500 to 1600 nm are obtained for a 250-mum-long semiconductor laser at the OSA resolution of 0.06, 0.1, 0.2, and 0.5 nm. The corresponding gain correction factor is about 9 cm(-1) at the resolution of 0.5 nm. The gain spectrum measured at the resolution of 0.5 nm has the same accuracy as that obtained by the Hakki-Paoli method at the resolution of 0.06 nm for the laser with the mode interval of 1.3 nm.

基于Qt的国际化图形用户界面设计与实现

一次开发多语言使用是国际化软件开发的主要目标。但是世界上的文字多种多样，它们的书写方向也有所不同，除了水平从左向右书写的英文、水平从右往左书写的阿拉伯文外，还有类似蒙古文这样垂直排列的文字，这对计算机图形用户界面提出了更高的要求，现有的计算机系统将这类垂直排列的文字沿水平方向输出，极不符合少数民族人民的习惯。在分析现有Qt库对类似阿拉伯文这样从右向左书写的文字的部分支持机制的基础上，我们设计并实现了支持四种方向模式的国际化的图形用户界面，现在它已经能够适应世界上几乎所有的文字。这对于软件国际化以及民族语言信息处理有重要意义。

在Qt上实现蒙文显示的设计与实现

随着软件产业国际化进程的发展,在操作系统中实现对我国少数民族文字的显示是一项具有挑战性和刻不容缓的任务,针对这项任务先分析了少数民族文字中蒙古文的语法特点和书写特点、桌面系统平台库QT的体系结构特点以及OpenType字体文件的特点,在此基础之上提出在QT中使用OpenType字体文件来实现蒙古文显示的详细实现方案,最后给出了目前该方案在项目中的实现情况和效果,并阐述了还有哪些地方需要进一步研究和改进。
