The dual scale automaton model is improved by introducing the rule of synchronization development, mechanism of reiteration and delay law of plant growth from the viewpoints of botany,which make it possible to generate almost all types of the inflorescences defined by botanists, and to simulate acropetal and basipetal flowering sequences.

通过在双尺度自动机模型中引入&同步生长机制&和&重复生长机制&，能够模拟所有植物学中给出的花序类型。并通过应用&生长延时机制&，实现了&向顶开花&和&向基开花&两种开花顺序的模拟，避免了L系统用成花信号控制的缺点。最后通过与L系统的比较，证明该方法简单实用

The study results indicate that as emission power increases, the peak power density on the section of a certain distance will increase firstly, then it will descend and that the peak light intensity on the section will increase with the increasing of spot radius of basic mode Gaussian beam. As the propagation distance increases, the peak light intensity on the section will descend gradually, and the laser energy will spread. The light intensity distribution exhibits straw hat shape on a certain conditions, in other word to say, the central light intensity is less than acroteric light intensity.

结果表明，无风稳态热晕效应存在时，随发射功率的增大，一定传输距离截面上的峰值功率密度先增人后减小；截面上的峰值光强随基模高斯光束的腰斑半径的增大而增大；随着传输距离的增大，截面上峰值光强在逐渐减小，能量在逐渐向周围扩展；在一定条件下，截面上的光强分布会呈现中心光强小于周围光强的&草帽型&分布。

When weig ht percentage of TiO 2 sol was10%-20%,the coating showed a good hydrophilicity after UV irr adiation for30～60min or sunlight irradiation for2～5hours. The hydrophil ic angle lowered to about 4degree and the surface of coated layer had the featu re of self-cleaning.

在TiO2溶胶质量分数为10%～20%时，该液体在基板上形成的涂层具有很好的超亲水特性，在UV光照射30～60min或阳光照射2～5h后，亲水角可低至4°左右，涂层表面呈现自洁特性。

Simply inferred the optical-rectification effect in the silicon, discovered the optical electric voltage aeolotropic rule through the experiment of observing the relation between the optical electric voltage and the light wave direction of polarization and the orientation of crystal changing when the Si/Al schottky barrier has been illuminated, and confirm the reason is that the existence of self-field destroy the crystal symmetry, produce second-order nonlinear optical-rectification effect, and the direct-current field which has been produced by the optical-rectification effect and the self-field affect mutually.

推导了硅中的光整流效应，并通过观测Si/Al肖特基势垒受光照时产生的光生电压与光波偏振方向和晶向的变化关系的实验，发现了光生电压的各向异性规律，并确定这是由于内建电场的存在使晶体对称性被破坏，产生二阶非线性效应的光整流，光整流产生的直流电场又与内建电场相互作用的结果。

But when John Lipsky, the fund's deputy head, announced its intention to do just that on January 31st, India's chief economic planner, Montek Singh Ahluwalia, deemed the proposal too modest.

然而，1月31日，当IMF常务副总约翰·利普斯基宣布这一打算时，印度的首席经济规划师蒙特克·辛格·阿卢瓦利亚却认为这个数字还太小了。

When the two peoples clashed, the Sumerians gradually lost control over the city-states they had so brilliantly created and fell under the hegemony of the Akkadian kingdom which was based in Akkad, the city that was later to become Babylon.

当著两个民族冲突时，苏美人逐渐的失去了他们辉煌的创造的城邦的控制权而归属与阿卡德王国基於古巴比伦阿卡德地区的霸权之下。这个城邦后来便成为了巴比伦。

If the straight-chain alkoxy group is too long, it's crystalline enhances, therefore thepolymer's solubility declines.

取代基长度进一步增加时，直链烷基自身的结晶性提高而柔顺性下降，聚合物可溶性反而有所降低。

At the beginning of the treatment with BF〓·Et〓O, the BF〓 will coordinate with the alkoxyl group to form intermediates, and the intermediates will then convert to the fluorinated products that generate more active species for styrene polymerization under the selected conditions.

在〓加入的开始时，BF〓和甲氧基形成配位中间体，然后此中间体转化成BF3配位的氟化物。

The longer fluorinatd alkyl chain on the three-ring was advantageous to the formation of smectic phase. The mesogens with chiral center located between fluorinated tail and mesogenic core exhibited chiral smectic C phase and other smectic phases when the alkoxyl adhering to the other side of the mesogenic core was of intermediate length.

三环系液晶化合物中较长的氟烷基边链有利于近晶相的形成，且当液晶核另一端的烷氧基链的长度适中时，在氟烷基边链和液晶核之间具有手性中心的液晶分子显示了手性近晶C相和其它液晶相。
