使有效

In the past, however, disregarding the above fact, a point source that creates a cylindrical wave was used to numerically validate the numerical dispersion relations of the FDTD-related methods.

过去，然而，忽视上述的事实，一个产生一个圆筒形的波点来源用来数字地使 FDTD-相关的方法数字散布关系有效。

Volcanic gas reservoirs of low permeability in the carboniferous of a basin are characterized by deep burial depth, complex genesis, many types, wide distribution and non-evident expressions in three-porosity log curves, as well as the variedvalues of density and compression wave of main four volcanic gas reservoirs (such as the basalt, andesite, dacite and rhyolite). So a number of effective methods based on three porosity log data cannot work in identifying the volcanic gas reservoirs of the carboniferous of the basin.

石炭系火山岩的低渗透气藏具有的埋藏深、成因复杂、类型多、分布广、三孔隙度曲线响应特征不明显等特点，并且主要的四种火山岩气藏：玄武岩、安山岩、英安岩、流纹岩的密度和纵波时差测井值差别较大，因此使基于三孔隙度测井资料的一系列识别气层的有效方法在该盆地石炭系火山岩气层的识别中无明显效果。

In this paper,a humanoid robot hand with five fingers and a palm（robot hand is called below for short） is designed.Based on the robot hand,the mathematical teaching model is studied,which takes the data glove as the input resource for the robot hand.

设计和实现了一个具有五个手指和手掌的仿人机械手，并利用数据手套对其进行了示教，使其能有效地完成复杂的作业。

"With Producer/Consumer, the data has a unique identifier. Using this model, multiple nodes can consume the same data at the same time from a single producer, resulting in more efficient use of bandwidth. Also, nodes can be easily synchronized."

根据生产者/消费者协议，数据有独一无二的索引，采用这种模式，多节点可在同一时间从单一信号点获取统一的信息，使带宽的利用更为有效，外节点也更易于实现同步。

"With Producer/Consumer, the data has a unique identifier. Using this model, multiple node s can consume the same data at the same time from a single producer, resulting in more efficient use of bandwidth. Also, node s can be easily synchronized."

根据生产者/消费者协议，数据有独一无二的索引，采用这种模式，多节点可在同一时间从单一信号点获取统一的信息，使带宽的利用更为有效，外节点也更易于实现同步。

You have to write a name for the rule and you can activate or deactivate the rule .

你必须填写规则的名称并且你能使规则有效或无效。

Congress needs to do its part by making the tax relief we passed permanent and burying the death tax forever.

议会应该通过使我们已经通过的减税政策永久有效和将遗产税永远的抛弃来完成它的角色。

The cubic effects, which formed from both the DCT-based on the block and the algorithm of sport compensation, have been eliminated effectively when video stream passes the deblock filter.

使视频图像数据经过去块滤波器后，更有效地消除了由于基于块的DCT变换和运动补偿算法而对码流形成的方块效应。

Your plan must be effective before January 1 in order for you to qualify for the 2007 tax deduction.

你的计划必须是有效的1月1日之前，以使您有资格参加2007年扣税。

Cultural conditioning makes the gap in urban area and rural area to certain extent, but urban and rural culture integration is a valid way to make up the respective culture defectiveness.

文化的制约作用使城乡文化差异在一定程度上造成了城乡发展的滞差，城乡文化整合正是克服各自文化缺憾的有效方式。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
