在...保证下

Because the electricity cannot be stored, the p ower system must maintain a continuous, instantaneous balance between power production and consumption in order to ensure the system stability and the role of reserve electricity is to avoid the risk of the imbalance between the power supply and demand.

电力产品不能储存，为保证电力系统的稳定，其供给与需求必须保持实时平衡，备用的功能显得尤为重要，因为它可以避免系统不平衡所带来的各种风险。在新的电力市场竞争环境下，电力备用的市场化运营问题也必然提到议事日程上。

Implementing good solid phase control, giving full play to peridium inhibitability of polymerized substance driven well fluid, keeping good rheologicability, sand carrying ability are considered to satisfy the requirement under well, reduce drilling resisting exte...

认为：在目前尚无更适合该地区新型钻井液体系的情况下，只要很好的实现固相控制，充分发挥聚合物钻井液的包被抑制性，保证钻井液具有良好的流变性、携砂性和滤失造壁性，也能较好地满足井下要求，降低阻卡程度，减少井内事故。

The invention has the advantages that by means of single film growth craft, supporting structures of a pier, a bridge leg, and a deck are accomplished, thus greatly lowering the difficulty and complicity of the craft; the pier, the bridge leg, and the deck are formed into a trinity, thus assuring the mechanical support of the whole micro bridge to be firmer and to have higher stability; meanwhile, the pier manufactured by means of the single film growth craft has a hollow shape, thus ensuring that the manufacturing process of the electrical channel of the micro-bridge structure is more simple, without the need of tapping in the pier; only simple photoetching craft is needed to guarantee the connection between the electrode at the upper end and the electrode at the lower end.

本发明利用一次薄膜生长工艺完成桥墩、桥腿和桥面的支撑结构，大大降低了工艺难度和复杂性，且桥墩、桥腿和桥面三位一体，使得整个微桥的机械支撑更为牢固，稳定性更高；同时，本发明利用一次薄膜生长工艺制作出的桥墩成空心状，使得微桥结构的电学通道制作过程变得更为简单，无需另外在桥墩中开孔，只需简单的光刻工艺即可保证上端电极和下端电极相连。

Compared with hard-switching inverter, the soft-switching inverter's power swatches turn-on at zero voltage or zero current conditions, zero switching losses in theory, which can improve the efficiency of the system and device power density, reducing the system electromagnetic interference and ensure a brushless DC motor performance and reliability.

与硬开关逆变器相比软开关逆变器的功率开关在零电压或零电流条件下导通，理论上开关损耗为零，从而可以提高系统的效率和装置的功率密度，减小系统的电磁干扰，保证了无刷直流电机的性能和可靠性。

And because high temperature high-pressure water is flowing and can be real-time renewed, experiment condition can be ensured to be stable and synchronized with unit's practical operating condition.

测试装置内的高温高压水是流动的，实时更新，可保证试验条件的基本稳定和与机组实际运行工况的同步，用于金属在该体系下的腐蚀研究。

In the sense of a row metrics,these conditions are very simpleand efficient,which supply some basic guarantees for obtaining an efficient pre-conditioning matrix.

在一种行尺度意义下，这些条件显得简单有效，为得到一个有效的预条件矩阵提供了某种基本保证。

But in both cases, the guarantee is there and is the most predominant feature of the system.

但在这两种情况下，保证有，是最突出的特点之一。

Finally, the paper is summarized. The solutions for alleviating county and township fiscal difficulties must base on the foundation of public finance system, and governments should take efforts to overcome the difficulties. The presidial government is dominant, central government is important, county government carries into execution; reformation of fiscal system is the primary, and the reformations of debt management system and administration system are necessary.

最后，总结全文，提出缓解县乡财政困难对策的指导思想应是在建立公共财政体系的目标下，各级政府共同努力化解县乡财政困难，其中省级政府应占主导地位，中央政府具有重要地位，县乡政府则是对策实施的主体；而具体对策中财政体制改革是主要对策，还需要健全县乡政府债务管理体系和深化行政人事制度等配套改革的协同保证。

Experimental results show that in the case of an unincreased playout delay the scheme could remarkably decrease the probability of lost media unit. The scheme could keep continuous presentation of a single media stream, and require inter-media synchronization between audio and video.

实验结果表明，该算法在不增加播放时延的情况下可以显著地降低媒体单元丢失率，保证单个媒体流的平滑播放，并实现音视频的媒体间同步。

They do not operate so as to shield a promisor from liability for a breach of contract. A force majeure clause will ensure that non-performance is no breach because no performance was due in the circumstances that have occurred.

但它们不是用来帮助承诺人逃避违约责任的，不可抗力条款是用来保证不履约将不构成违约，因为在不可抗力发生的情形下没有履约义务。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
