使加速

We can imagine a spacecraft carrying a big area of him film to collect solar energy, with an ion?jet engine to produce thrust powerful enough to boost a spacecraft to a speed of 160 km a second.

我们可以设想一艘航天器，它装载着收集太阳能的巨大薄膜，并载有一个能产生强大推力足以使航天器加速到每秒160公里的离子喷气发动机。

Under the given project scheduling specified by the upper-level algorithm, combined with a critical chain-based heuristic, the lower-level genetic algorithm reallocates the resources to shorten the project duration so that the rate of converging to the global optimum district is improved, and a variable mutation probability is developed to avoid premature convergence.

在由上层算法确定的调度顺序下，下层遗传算法结合基于关键链的启发式算法，对系统资源重新优化配置，使算法加速向最优解区域收敛，并在下层设计了随迭代代数增加的可变变异概率，以避免早熟收敛。

In fact, it is probable that little gain can be made by selecting a geometric compression ratio which would raise the gas temperature by adiabatic compression behind the temperature of the hot zones (except for accelerated heating by gas density and proximity effect, which would make it possible to achieve higher RPM).

事实上，它很可能使小增益可以作出选择几何压缩比率，从而将提高的效果，气体温度接近后面的绝热压缩气体密度和温度的热区（除加速它加热能够达到更高的转速）。

The stock market can supply for capital with the remaining, make the dispersions funds concentrate, accelerate the funds with the turn over of stock certificate, realizes the social resource install reasonable.

通过证券市场，可以调剂资本的供求和余缺；使分散的资金集中化；加速资金和证券的周转；实现社会资源的合理配置。

Considering the design parameters of the BEPCⅡ, in the case of one cavity type being adopted, the thesis analyzes the RF performance of accelerating mode, the suppression of higher order modes , and the restriction caused by HOMs against beam current threshold.

结合BEPCⅡ的设计参数，论文对其中一种腔型在BEPCⅡ上使用时加速模式的微波性能、高次模的抑制效果以及高次模对储存流强阈值的限制等方面进行了分析，并在铝模型腔上测量了加铁氧体高次模抑制器前后，超导腔中各种谐振模式的有载品质因子及其频率的分布。

These facts conflicted with current theory and were not explained until 1905, when Einstein produced his quantitative law and developed the theory of quanta of light or photons, which was verified much later by Millikan.

此后，莱纳德又继续拓展赫兹关于光电效应的研究，他分析了在高真空环境下光电效应的特性和本质，证明了当紫外线照射在金属上时，会使电子从金属表面逸出，并在真空中传播，电子在电场中被加速或减速，电子轨迹在磁场中改变。通过精确的实验，他证明发射的电子数量正比于入射光所带的能量，而电子的速度，或者说它们的动能，却与入射光能量无关，当入射光的波长减小时，电子速度增大。这个事实与当时的理论是相冲突的，经典物理学无法解释莱纳德的光电效应实验结果。

In addition, using MRA to increase the global searching speed and ability of the algorithm.

小波多尺度分解方法的引入，使算法加速了搜索速度，并提高了全局寻优性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
