The sidereal day, two successive vernal equinox on the transit time interval.

恒星日，春分点连续两次上中天的时间间隔。

In an update of its 2002 recommendation, the USPSTF now recommends that adults aged 50 to 74 years be screened in 1 of the following ways: every year with high-sensitivity fecal occult blood testing; every 10 years with colonoscopy; or every 5 years with flexible sigmoidoscopy plus interval high-sensitivity FOBT.

在针对2002年建议的更新中，USPSTF目前建议50至74岁成人应该接受以下筛检：每年接受高敏感度粪便潜血检验；每10年接受一次大肠镜检验；或是每5年接受一次乙状结肠镜加上间隔高敏感度FOBT。

The description of network delays including characteristics and effects are also covered and the uniformed mathematic models for NCSs with four different structures are derived. Furthermore, the controller basing on state prediction and compensating time delay is designed. Sufficient and necessary stability conditions for systems with different transmission policies such as perfect transmissions, delayed transmissions and time-varying transmissions are obtained as simple eigenvalue tests of certain test matrices. And in the end, effects of model error over maximum communication interval are analyzed. Numerical examples show the feasibility and efficiency of the proposed methods.

首先介绍了网络控制系统中数据包的传输情况以及基于模型结构方法的基本思想，并针对四种不同拓扑结构的控制网络分析了网络时延的性能，进而给出了统一的数学模型；然后，提出了基于状态预测的具有时延补偿功能的状态反馈控制器的设计方法，并针对完美传输、延时传输及时变传输三种数据传输策略，分别研究了控制系统的稳定性问题；最后分析了模型误差对最大通讯间隔的影响；仿真结果表明了设计及控制方法的正确性和有效性。

We can now answer questions concerning the simultaneity of, or the time interval between, two events in different places.

现在我们可以回答关于同时性的问题了，或者不同地方的两件事情之间的间隔时间了。

It can either be a single file or more than one files uploaded during the one week interval.

它可以是单个文件或多个文件上传在一周的时间间隔。

Suppose that, instead of a single slit, or two slits side by side as in Young's experiment, we have a very large number of parallel slits, all of the same width and spaced at regular intervals.

设想我们用非常多的平行狭缝像杨氏实验的双缝一样那样替代单缝，这些缝以相同的缝宽和相同的间隔排列。

If a single space is used it is interpreted as whitespace.

若使用一个间隔，则看作为空白。

Separate each event with a single space.

用一个单独的间隔来分开每个事件。

Avoid double coat buttons, while the single-breasted or single button on the more appropriate, and the button layout and buttons are required to avoid too much.

外衣切忌双排纽扣，而单襟或单行纽扣就较合适，并且纽扣间隔和纽扣都要避免太大。

Have originally designed of variable frequency sinusoidal wave generator 、 the frequency of measurements, and the interval between cycles of equipment.

本设计以单片机为核心设计了一种可变频率的方波、正弦波的发生器，并可测量频率、周期和时间间隔的仪器。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
