查询词典 for the time

However, keywords can only represent the simple content, which easily dissever the relevancy of the content The deep-content representation and application are not developed, so semantic navigation is not satisfied at present. Time mechanism is a kind of navigation mechanisms that uses time for the signpost, and determines navigation route according to the time of occurrence.

时序机制指以时间为导航路标、根据事物发生的时间顺序确定访问路径的一种导航机制，主要应用于WWW信息空间中以时问顺序为线索组织信息的结构中；空间机制指依据对象间的空间关联，为用户指引路径，提供导航路标的机制，应用于具有空间特征的结构中；社会机制指利用先行者的经验、建议为后来者指引路径的行为，原来主要应用在推荐系统、协作系统中，目前已经在主流的信息检索系统中得到了应用，如在CNKl知识网络服务平台（CNS 5.0）中的应用。

The result makes clear, force of the grinding when using emery wheel of cast-iron bond diamond to undertake ELID grinding asks at any time scarcely change and change, and the change that adopts the grinding force when common grinding means undertakes grinding to let time increases ceaselessly, online electroanalysis the grinding function that nap makes emery wheel keeps good from beginning to end in grinding process, be helpful for saving time of emery wheel nap, improve treatment efficiency.

结果表明，采用铸铁结合剂金刚石砂轮进行ELID磨削时磨削力几乎不随时问的变化而变化，而采用普通磨削方式进行磨削时的磨削力随时间的变化不断增大，在线电解修整使砂轮在磨削过程中始终保持良好的磨削性能，有利于节省砂轮修整时间，提高加工效率。

根据实验的目的和原理，自行研制了两套实验系统：一套为光斑实时测量和记录系统，另一套为光强实时测量和记录系统。

The worst performing biometric technology was facial recognition, which failed 31% of the time for able-bodied participants and a farcical 52% of the time for disabled participants.

表现最差的生物识别技术是面部识别，未能31 ％的时间为健全与会者和可笑的52 ％的时间内为残疾人士参加。

For the requirement of instantaneity, an implicit real-time discretisation is used, and the equations are integrated in a fictitiously pseudo time. This approach allows the real-time step to have two-order accuracy and accelerates the speed of convergence. Based on the theory of Mr. John K. Dukowicz and the algorithm of Mr.

在非定常计算中，本文同时采用当地和虚拟时间步，即双时间推进，在每个真实时间步上采用虚拟时间进行定常迭代，从而不但使时间迭代具有二阶精度，并使计算时间大大缩短，这样程序与定常程序在算法思想上一脉相承。

Then we contrasted the two groups from the first time of flatus,first time of leaving bed,the sleeping time during 24 hours and 48 hours,and the number of hospitalization days,hospital fees,satisfaction with the effect and measures for the management of pain.

目的 探讨手术后疼痛管理在普外科无陪护理病区中开展的效果方法（1）将2006年9～12月开展无陪护理后来我科住院并实施规范的手术后疼痛管理的521例患者设试验组；将2006年3～6月开展无陪护理来我科住院并实施常规术后止痛的456例患者设为对照组。

Compounds 1 and 2 were new xanthones, and compound 3 was isolated as a natural product for the first time, and compounds 4 and 6 were isolated for the first time from this genus. The antioxidant activities of all compounds were evaluated by ABTS,FRAP and DPPH assays respectively. Compound 9 showed significant activity by the ABTS and FRAP assays. Compound 1 showed significant activity with IC50 value of 0.31 mg·L-1 in DPPH assay.

化合物1，2为新化合物，化合物3为新天然产物，化合物4，6为首次从该属中获得；化合物9在ABTS和FRAP模型中显示出显著的抗氧化活性；化合物1清除DPPH自由基能力的IC50为0.31 mg·L-1。

In part one (chapter 2-3), two new methods and systems of optical parallel logic operation are studied. Triple-in Double-out shadow-casting logic operation system is proposed and realized for the first time. Based on this, optical full adder and 3-bit decoder array logic have been obtained. It is the first time to use coding pattern and different reading-writing model to realize BSO-PROM optical parallel logic operation where the time-order operation is avoided, so that the computing speed of optical parallel logic gate which uses this kind of spatial light modulator is increased, and it is successfully used in optical symbolic substitution .

在第一部分，对两种新的并行光学布尔逻辑运算方法及系统进行了研究：首次提出并实现了三输入、双输出铸影光学逻辑运算系统及其由此得到的光学全加器，并提出一种以此为基础的3-比特译码器阵列逻辑，首次利用图形编码和不同的读写模式实现了无时序操作的BSO-PROM光并行逻辑运算，大大提高了这种空间光调制器用作光并行逻辑门的运算速度，使之成功地用于光学符号代换之中。

Using the time-gain compensation technique to compensate for ultrasonic wave's weaking when transmitting in the air,and reduce the fluctuation of echo signal.The peak time detecting circuit which is composed of full-wave rectification circuit and differential circuit can detect the reach time of echo signal accurately.

和其他方法相比，如激光测距、微波测距等，由于声波在空气中传播速度远远小于光线和无线电波的传播速度，对于时间测量精度的要求远小于激光测距、微波测距等系统，因而超声波测距系统电路易实现、结构简单和造价低，且超声波在传播过程中不受烟雾、空气能见度等因素的影响，在各种场合均得到广泛应用。

At the same time, oceanographer Dr Kate Stansfield will study the deep ocean currents in the Cayman Trough for the first time and geochemist Dr Doug Connelly will hunt for volcanic vents on the ocean floor.
