升降

The design of the PLC as a tool to the elevators for various operating control.

本设计就以PLC作为工具对升降电梯的各种作进行控制。

This aircraft uses control-figured vehicle design and nine independent control planes: two forward wings, two forward wing flaps, two inside elevons, two outside elevons, and one vertical rudder.

同时歼十使用了数字飞控设计，有9个控制翼面：两个在前翼，两个在前襟翼，两个在升降副翼中，两个在副翼之外，还有一个在垂尾上。

High aspect-ratio flying wing configurations usually use split-drag-rudder and a set of elevons to fulfill the lateral-directional control, without the traditional vertical tail and rudder.

大展弦比飞翼构型取消了垂尾和方向舵，通常采用开裂式方向舵和多组升降副翼组合来实现滚转和偏航操纵。

REE plays an important role in rec ognizing the boundaries of sequence and system tracts and reconstructing sedime nt lithofacies paleogeographic conditions, including ancient water depth,ancie nt salty, pH value and Eh value of water body,oxidation and reduction conditi on and eustacy of lake level.

稀土元素对识别层序、体系域边界及恢复层序框架内的沉积岩相古地理(古盐度、古水深、水体的pH及Eh值、氧化还原条件、湖平面升降变化)都具有重要意义。

The eustasy explanation put forward by Rona is also possible .

罗纳提出的海面升降也是可能的。

Lithology changes of Qom formation were controlled by eustasy change.

海平面升降旋回变化控制着Qom组内部各段岩性变化。

It is proposed that clear definition and discrimination of some relevant concepts and relationships on sea level and sea level change, eustasy and relative sea level, high frequency sea level and composite sea level, sea level rising falling, sea level fluctuation and sea level oscillation, sea level change and transgressive ...

对利用沉积记录来研究海平面变化的重视程度很高，但对海平面变化对沉积盆地的影响注意甚少。建议关注海平面升降变化对盆地充填物的作用，对沉积型矿床的控制和对大陆边缘地壳变形的反弹作用过程的研究及定量模拟是一个重要方向，它可能为大陆边缘动力学研究提供一方面的思路。

On the basis of the basic principles of sequence stratigraphy,the formation of cyclical sedimentary stratum is driven by eustasy which is periodic,and by analysing the seismic,well log and nano-microfossil data of Pearl River Mouth Basin,an integrated study was conducted which is on the sequence stratigraphy of lower and middle Miocene stratum within and around Kaiping Sag .

以层序地层学基本原理——周期性海平面升降控制旋回性地层沉积——为指导，根据地震、测井和古生物资料，对珠江口盆地开平凹陷及其围区的早中新世—中中新世地层进行系统的层序地层分析，认识到该区的层序地层学特点取决于其特殊的古地理位置。

Some specific problems in connection with blade modeling, such as spanning characteristic mesh, interpolation of curve face modeling, precise presentation arc by second order NURBS curve, node interpolation algor...

深入探讨了在叶片构造过程中遇到的剖分网格确定、插值曲面构造、圆弧的二次NURBS曲线精确表示、NURBS曲线节点插入算法及其升降阶等关键性技术问题。

In light of the characteristics of non-linearity,heavy lag behind,strong coupling, time change, heavy working environmental interference as well as stochastic disturbance and according to the self-adapting control theory the control device with PLC as its core element is used to realize the automatic and accurate control on the lift-up and fall-down of the electrode of electric arc furnace.

针对电弧炉的非线性、大滞后、强耦合、时变、工作环境及随机干扰较强的特点，应用自适应控制理论，采用PLC为核心控制部件，来实现电弧炉电极升降的自动准确地控制。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
