使波动

Meantime, through great deal of experiments, spark advance angles, ignition dwell angles, start injection width and electrical throttle threshold were optimally controlled. At last, quick response time of hydrogen-fueled engine was realized, speed stability after successful start was controlled. At the same time, backfire, preignition and fire a gun in the start state of hydrogen fueled engine were avoided.

同时通过大量试验调试，对点火提前角、点火闭合时间、喷气正时、电子节气门开度、起动喷气脉宽进行优化控制，使发动机起动响应时间快，起动后转速波动平稳；同时避免了氢燃料发动机起动时易出现的回火、早燃、放炮等异常燃烧现象。

Some thought of the queerness of her deed affected her.

她自己出格的举动也使她情绪波动。

Depending on the character of Lamb wave propagation , thedamage scat tering signals were time reversed and reemit ted to the damage , and then they will arrive at the damage synchronously so that the damage scat tering signal caught again will be amplified. Details about the time reversal amplifying process were analyzed and given. Based on the focalization ability of time reversal theory to the wave origin , the wave propagation was rebuilt by an image method which displays the damage as the focusing point .

根据信号传播自身的特性，研究采用时间反转聚焦方法使损伤散射信号能量叠加放大，从而提高信号的信噪比，分析给出了具体的损伤信号时间反转聚焦增强过程；利用时间反转法对波源的自适应聚焦能力，重建信号传播波动图，通过信号聚焦显示损伤位置和区域。

The development of the index have catched up with the development of the economy and the society.We can ameliorate our index in many ways. We can fetch in new index,such as rewarding index of investment capital, it can be used to avoid the ruleless fluctuate caused by unregular revenue. We can fetch in the accrual ability of immateriality assets and "social responsibility" to enhance the deal of non-currency info and knewledge assets info. We can fetch in the method of key index analyse through relevancy analyse to conform the sequence of significance.

我们可以从多方面对指标进行改进，可以通过引进新指标如投资资本报酬率来克服因非经常性收益使企业业绩出现忽高忽低地波动的问题；可以通过引入无形资产获利能力评价指标、"企业社会责任"的概念来加强企业非货币性信息、知识资产信息在评价体系中的份量；通过引进企业获利能力关键指标的灰色关联分析来科学地确定指标的重要性顺序，以减少指标使用的盲目性。

Currency substitution is the inevitable problem during the developing course of developing countries,which will make exchange rate fluctuate frequently、influence the independence of monetary policy、decrease government's inflation tax and seigniorage、slack social public's confidence in domestic currency , only to the stability of macro-economy and the effective power of economic policies.

货币替代是发展中国家在开放过程中所不可避免的问题，它的存在会使汇率频繁波动、影响货币政策独立性、削弱政府的通货膨胀税和铸币税、涣散社会公众对本币的信心等，这会严重影响国家宏观经济的稳定和经济政策的效力。

The vertical torsion spring laser guide beam arm is designed by analytic method, and the load curve is mapmaked in the permited fluctuation range. A torsion spring curve is designed to match with the VTSLGBA′s feature curve, and the torsion spring design parameter can be confirmed according to the match result.

采用解析法优化设计了立式扭簧激光导光臂，在允许的工作波动范围内绘出导光臂的载荷曲线，然后设计出一条扭簧的扭矩曲线使其与导光臂的载荷曲线相匹配，再根据匹配结果确定扭簧的设计参数。

Under certain trading conditions it may be difficult or impossible to liquidate a position. This may occur, for example, at times of rapid price movement if the price rises or falls in one trading session to such an extent that under the rules of the relevant exchange trading is suspended or restricted. Placing a stop-loss order will not necessarily limit your losses to the intended amounts, because market conditions may make it impossible to execute an order at the stipulated price.

在某些交易状况下，可能很难或无法执行头寸，例如当价格急速波动时，若某一交易时段之价格上涨或下跌达到某一程度，致使依据相关交易所的交易规则被暂停或禁止交易，便可能发生上述状况，下达止损订单不一定就能将客户的损失限制在预定的范围内，因为市场状况可能使其无法按预定价格执行停损指示。

The optimized structure can more reduce thrust tipple, which provides ideal condition for precision machining and high dynamic response of servo system.

并且其优化后的结构使电机推力波动进一步减小，为伺服系统的超精密加工和高动态响应提供了理想的条件。

The nature of the wave motion in sound can be made clear by considering the tuning fork.

对于音叉的考查可以使我们清楚地理解声波波动的本质。

Home bias may play a role in the investment strategy of all investors , which may lead to an undiversified portfolio causing unnecessary volatility , said Barnerjee .

表示，只投注重资国内股票的投资策略会使投资组合就不够分散，并会导致不必要的起伏波动。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
