Among the large number of nonlinear absorbers, the material applied most extensively is phthalocyanine reverse saturable absorption compound which is organic large molecule with central symmetry two-dimensional π-electron conjugate system. In the off-resonance condition, its absorption coefficient will raise along with the increasing of incoming light intensity, which shows its reverse saturable absorption properties.

在非线性光学材料中目前最具应用价值的是酞菁类的反饱和吸收材料,这是一类具有中心对称二维π电子共轭体系的有机大分子,在非共振激发条件下,吸收系数往往会随入射光强的增加而增加,体现反饱和吸收。

And the culturable bacterial degraders were increased from 10^6CFUg^(-1) soil to 10^8CFUg^(-1) soil after inoculating with the degrader. Moreover, the bacterial population increased faster in 100mgg^(-1) microcosoms than in 500mgg^(-1) microcosoms, revealing that the inoculated bacteria could survive and enhance the biodegradation of chlorophenol in cuntaminated soil.

接种外来微生物后,土壤中可以培养的氯酚降解菌的总数从开始的10^6CFUg^(-1)增加到10^8CFUg^(-1),并且,在氯酚含量为100mgg^(-1)的土壤样品中,微生物数目的增加比在氯酚含量为500mgg^(-1)土壤样品中更快。

The turnover in the territory increased by 20% in 1993 and by 25% in 1994. copyright dedecms

该区域的营业额在1993年增加了20%,在1994年增加了25%。

First, from room temperature to 500oC, the shell structure is amorphous with crinkly and airtight character. The shell structure begins to change into γ-Al2O3 and α-Al2O3 at 900oC. The surface of shells shows nano-sized pores at 900oC from SEM and BET analyses. When heated to 1000oC and 1100oC, the shell forms stable α-Al2O3 structure with smooth surface. Cracks often occur at the triple grain junctions. The specific surface area and the total pore volume of the hollow spheres increase with the calcination temperature.

首先,将锻烧温度由室温提升至500℃时,球壳属非晶相皱褶状致密结构;在900℃时开始有γ-Al2O3相及些许的α-Al2O3相出现,由SEM及BET结果得知,900℃之球壳表面有许多奈米级孔洞出现;当加热至1000℃和1100℃时,球壳形成稳定相之Al2O3结构,壳层表面趋於平滑,且球壳在晶界处有微裂缝存在;由BET 结果得知,比表面积及总孔洞体积会随锻烧温度之增加,有增加之趋势。

Modified polylactic acid vector have better biocompatibility with Schwann cell, and their cytotropism were improved.

改性后的材料细胞生物相容性良好,其表面亲水性增加,但2材料可能在改性过程中表面酸度增加,在处理上有必要改进。

The process of ecological degradation in the vicinity of Shaoguan Pb/Zn smelter may be summed as: heavy metals and acidic deposits from the waste gas from smelter resulted in the vanishment of the sensitive plant species, increasing accumulation of heavy metals in soils and acidification of topsoil worsened the chemical properties and then shallow-rooted plant, mainly the herbaceous, vanished. With the demolishment of the vegetation cover, increasing water-soil erosion worsened physico-chemical properties of soil and, subsequently, some woody plants disappeared and barren land was finally appeared.

该生态系统的退化过程可以归纳为:来自于冶炼废气的重金属和酸沉降导致了敏感植物的消亡,丧失了对土壤的缓冲保护作用;重金属在土壤表层的积累,酸性物质在土壤表层的增加导致的土壤酸化以及由此引发的有机质与养分的淋溶和重金属及Al的活性增加,加剧植被的快速退化,特别是浅根植物的衰亡;地被层的破坏,导致水土流失和土壤侵蚀加深,进一步恶化表层土壤的理化性质,一些木本植物随之消失,最终形成光板地。

Deterministic search process restricts its flexibility, determined on the basis of fixed TS, according to the information of moving, add a probability function to the evaluation function, increase the probability factors , broad the search area, makes a better solution a better chance of being selected.

T S中确定性的搜索过程制约了它的灵活性,所以在禁忌搜索原则确定的基础上,根据搜索中的移动信息,增加概率性因素,在评价函数中增加一个概率函数,把确定性选择过程变为概率性的,从而改进搜索方向,拓宽搜索领域,使得更好的解有更大的被选中的机会。

Triglyceride content in the fat body was as high as 75% at the initial stage of pupation, but decreased gradually with the development of the pupae. Accordingly, triglyceride content in the ovary was only 20% at the beginning and increased to 64% before eclosion, and the content of diglyceride and free fatty acids in the blood also increased significantly. This suggests that fat in the ovary is transported from the fat body through the blood.

在化蛹初期,脂肪体中甘油三脂的含量高达75%左右,随着蛹体发育而逐渐降低;与此同时,卵巢中甘油三脂的含量在化蛹初期仅为20%,到羽化前增加到64%;血液中甘油二脂和游离脂肪酸的含量也有明显增加,说明卵巢中的脂肪是由脂肪体经血液转送而来的。

At present, the wireless devices in general to bring the whole antenna, omni-directional radio antenna to the antenna axis, was "donut"-shaped radiation field; directional antenna is highly directional, in the small angle of radiation is totally outside the scope of signals ; the use of removable external antenna equipment can gain antenna, the antenna can not increase in the case of radiated power to increase communication distance.

目前的无线设备一般自带全向天线,全向天线电波以天线为轴,呈"面包圈"状向外辐射;定向天线具有极强的方向性,在小角度的辐射范围外是完全没有信号的;使用可拆卸天线的设备可以外接增益天线,可以在不增加天线辐射功率的情况下增加通讯距离。

While it has also given the granule diameter distribution curve of different types of starch.

结果表明:随着淀粉乳浓度的增加,FBRM测得的淀粉颗粒粒径呈现先增加后减小的趋势,当浓度达到10%时,粒径大小趋于稳定;在高浓度淀粉乳中,搅拌速率对淀粉颗粒粒径的影响较为显著,在低浓度淀粉乳中,则没有显著的影响;采用浓度小于50%的乙醇和异丙醇以及高于75%甘油作为介质时,可以得到较为稳定的粒度分布;不同种类淀粉颗粒的粒径分布曲线趋势不同。
