He made the "calendar time", the projection has 365.2425 days a year, with the Earth around the week, only 26 seconds, with the common world of the Gregorian calendar as one cycle, but the morning than the Gregorian calendar three hundred years.

他制成了《授时历》，推算出一年有365.2425天，跟地球环绕一周的时间，只差26秒，跟目前世界通用的格里高利历的一周期一样，但比格里高利历早三百年。

The paper will show that, if appropriate time information are added into the signals over the Loran-C data channel (studied in the first part of the paper) or in which the current multi-chains signals can be skillfully dealt with(studied in the second part of the paper), the independence of Loran-C for precision timing can be perfected, as well as the precision of timing signals and the automatization level of UTC synchronization can be improved, thereby the Loran-C can be acceptant and employed widely.

本文通过研究认为，在罗兰C信道上增加合适的时间信息或利用多链罗兰C信息，能够完善罗兰C高精度授时的自主性，提高定时信号的精确度和用户定时的自动化水平，从而提升该系统的可利用度和可接受程度。作者所做工作及主要成果如下

Lobal Positioning System is the only perfect kind of new-generation precise satellite navigation system. GPS has been widely concerned on military and the civilian since it was used, which has been developed rapidly, for its characteristics of providing all-global, continuous, real-time and high accuracy 3-D positioning and velocity as well as time.

PS是目前世界上唯一最完善的新一代精密卫星导航定位系统，由于其具有提供全球范围的、连续的实时三维位置、速度信息和精确授时等功能，自投入使用以来，就得到了各国军事和民用部门的普遍关注，并得到了迅猛地发展。

In order to resolve these problems, an independent-developed microseismic monitoring system called MEMS has been developed to aim at this international problem.

为此研制了一套以三分量MEMS检波器为核心硬件的微地震监测系统，并结合GPS系统对监测过程进行精确授时。

The mRNA level of per gene under high temperature was higher than that under low temperature when the larval and pupal stages were under the same photoperiod.

温度和光照是昆虫近日节律基因表达的授时因子，也是影响家蚕滞育的决定因素。

The two transpolar shortwave time signal circuits,Moscow and Irkutsk to the Great Wall Station in Antarctica, are used to study the fading characters for shortwave long circuit.

为了研究过极区的短波长电路的衰落特性，在南极长城站收测莫斯科、依尔库茨克的短波授时台信号，并给出各频率对应的衰落深度、衰落率、衰落平均持续时间等参数的统计特征和衰落幅度分布曲线。

Using RCT can resolve the problems of inaccurate time and the cumulating among most time controller s.

采用无线控制授时技术，解决了大部分时间控制器的时间控制不精确，误差累积严重的问题，且成本低，电路简单。

World wide web is so limited in China and most industry sites are built in rural area that it is difficult to make use of network to reach synchronization, thus, the synchronization board in this thesis is to set up a emendation system in every computer and realize synchronization through emending their system time.

由于我国互联网普及范围还很有限，并且许多工业站点、电网站点等建在比较偏僻的地方，难以实现网络授时。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
