对流

The system only proceeds re-editing for the tail of one stream and the front of another stream which across the editing point in editing operation to generate single stream by combination two streams, and utilizes rest of the stream as formerly, thus to reduce the worsening of signals quality caused by re-editing for the stream to the lowest.

在合并两个流产生单个流的编辑操作中，系统只对跨越编辑点的、一个流的尾部以及另一个流的前部进行重新编码，并且照原样使用流的其余部分，从而把对流重新编码而造成的信号质量的恶化降至最低。

I think there was only vent per box, no opportunity for cross ventilation, and the vents were toward the bottom, not the top where heat would normally head.

我觉得每个盒子只留一个散热孔，会造成空气无法对流，而且这个通风孔是朝下的，而不是在热气散发的顶部。

Before the occurrence of the rainstorm there are the energy front, the occluded high energy tongue and the centre of the high energy.

结果表明，该次暴雨的出现和早期出现的高能系统及深厚对流不稳定层有一定的对应关系。

According to thermodynamic law of conservation of mass and energy and heat transfer theory, a group of differential equations on thermal balance of cover, thermal balance of indoor air, thermal balance of multi-layers of north wall, thermal balance of multi-layers of soil, thermal balance of multi-layers of north roof and thermal balance of plant were built.

该文建立了日光温室热环境模拟模型，定量描述了日光温室内的太阳辐射、对流换热、辐射换热、热传导、自然通风和水分相变带来的潜热对日光温室热环境的影响，根据质能平衡和传热学理论，得到一组关于覆盖物、室内空气、温室分层后墙、分层地面土壤、分层后坡和作物热平衡的微分方程组。

This paper takes 9 kinds of different parameters high-property flame-resistant fabric which were often used for firefighter clothing as samples, TPP values and the time to 2 degree burn of the samples were tested through thermal radiation and thermal convective integrated experiments.

以9种不同结构参数的消防服用阻燃织物作为研究对象，采用FPT-30A火焰防护性能测试仪测试了织物在热辐射和热对流综合作用下，织物的热防护性能TPP值和二级烧伤时间t2。

In the new model the tectonic driving force is not the mantle convection, but the relative movement of horizontal shear between the continental lithosphere slab due to A-type subduction characterized by spreading and separating and the asthenosphere.

新模式不是以地幔对流运动，而是以扩张分离A型俯冲的大陆岩石圈板片与软流圈之间的水平剪切相对运动机制作为它的躯动力。

The whole flow field represents the characteristics of anisotropies for the fluctuation of the centerline velocity lacking of self-preserve.

对流场紊动量的分析表明，射流的紊动强度在射流的中垂线上不具有自相似性，射流在整个流场中是各向异性的。

The results demonstrate that mixing bubble to pure jets makes the profile of water elevation flatting, the velocity distribution of centerline rising and the fluctuation of velocity near surface fluctuating. The fluctuation of the centerline velocity lack of self-preserve and the whole flow field represents the characteristics of anisotropies.

对比纯射流情况，掺气射流中掺气使得射流中线附近的流速增大；对流场紊动量的分析表明，掺气使射流中心处水面的紊动加剧，掺气射流的紊动强度在射流的中垂线上不具有自相似性，射流在流场中表现为各向异性。

The transplant model is established in groundwater at saturated state based on identical conditions presumption, directed to wet method discharge of coal fly ash. It gave out the model solve and calculated transference regularity using the Femlab for the trace element in groundwater in 20 years.

针对传统的对流－弥散理论和粉煤灰湿法排放的特点，基于相应的假定条件建立起饱和状态下污染物在地下水中的迁移模型，给出了模型的求解过程，并用Femlab软件模拟计算了微量元素20年内在地下水中的迁移规律。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
