The new technology makes the sucker rod string downwards easily by applying a downward hydraulic force at the bottom of the hollow sucker rod string, which effectively solves the problem of large drag force on the downstroke in the present technology of this kind.

介绍了一种新型空心杆采油工艺技术，这种技术采用了具有液力反馈原理的空心杆抽油泵，该泵的特点是能有效地减小空心杆的下行阻力，并能增加抽油杆的下行动力。

According to virtual router advertise, virtual address of master device is used to upstream access device, which enables downstream traffics to have the same flow direction with that of upstream traffics via routing.

虚拟路由通告的方法则把主设备中的虚拟地址通告给上行接入设备，从而下行流量可以通过上行设备的选路，使上下行数据流向保持了一致。

In TDD-CDMA system, the different asymmetrical requirements between uplink and downlink in different Base Station and different time will generate serious inter-cell interference. From the interference point of view, Dynamic Channel Allocation is treated mandatorily on TDD-CDMA systems.

摘要在TDD—CDMA系统中由于对上下行不对称业务的需求，使得不同小区间的上下行切换点不同，因此会产生严重的小区间干扰，需要使用动态信道分配算法。

Determining whether the time that RNC transmits downlink FP frame is stable or not: if unstable, determining the nonsynchronous reason is that the time that RNC transmits FP frame is unstable and determining whether the time that NodeB transmits uplink FP frame is stable or not: if unstable, determining the unstable reason of transmission channel is that the time that NodeB transmits uplink FP frame is unstable; D.

确定RNC发送下行FP帧的时间稳定或不稳定，在不稳定时将传输信道不同步原因确定为RNC发送下行FP帧的时间不稳定，并确定NodeB发送上行FP帧的时间稳定或者不稳定，在不稳定时将传输信道不稳定原因确定为NodeB发送上行FP帧的时间不稳定；D。

In order to observe the influences of the descending projections from the subnucleus reticularis dorsalis on the neurons in the spinal cord and caudal spinal trigeminal nucleus,by using an immunocytochemical method,we investigated the c-fos expression within spinal cord and Vc after kainic acid microinjection into the SRD of the rat.

为了观察起自延髓网状背侧亚核的下行投射对脊髓和三叉神经脊束核尾侧亚核神经元活动的影响，将微量海人藻酸注入大鼠SRD中，致SRD神经元兴奋，在SRD下行通路的作用部位引起c-fos的表达。

There exists downward inertial gravity waves in mesosphere, their phase fonts moves upward, and polar ellipses are anti-clockwise with increasing heights.

中层大气中存在下行惯性重力波，它们的等相面向上移动。通过分析它们的偏振关系，发现下行惯性重力波的偏振椭圆随高度增加而逆时针旋转。

Results of synthetic and field data examples show that, compared with conventional method, separated wavefields using local slopes are clean and amplitudes are maintained. The interference between upgoing and downgoing wavefields can be eliminated better.

模拟和实际资料处理结果表明，该方法与传统方法相比，分离出的上、下行波噪声假象少，振幅保持好，更好地消除了上、下行波的相互影响。

Based on difference between upgoing and downgoing wavefields in vertical seismic profiling data, a new method to separate upgoing and downgoing wavefields using local event slopes attribute is developed.

基于垂直地震剖面资料中上、下行波视速度的差异，利用地震剖面同相轴局部斜率属性参数，提出了一种分离上、下行波场的新方法。

To overcome the above described drawbacks,P.W.Baier and other researchers propose a novel multi-user transmission scheme for the downlink of TD-CDMA termed joint transmission. This paper discusses the application of JT technology in the FDD system,and proposes a new solution: Through feedback signal,channel pre-estimation is accomplished at the base station.

为此提出了名为联合传输的多用户传输方式，可以利用TDD模式上下行链路移动无线信道脉冲响应相等的优点，只在上行链路对信道进行估计，下行链路利用估计得到的信道冲击响应值，把在移动台判决传输信号的任务交给基站来完成，利用这种技术可以提高系统性能和减少系统复杂性。1系统模型及JT原理联合传输技术[1～3]，可由信道传输概念引出，如图1所示。

While the ascending melodic minor follows the natural minor, with the sixth and seventh degrees of the scale sharpened as in the major scale, the descending melodic minor scale follows the natural minor. The descending melodic minor scale of A minor can, therefore, be played on the white notes of the piano, starting on A, and would be:

上行旋律小调与自然小音阶的模式相同，大音阶的第六级和第七级音阶仍为升，下行旋律小调遵循自然小调模式。A小调下行旋律小调为在钢琴的白键上演奏，开始于A调，为

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
