At Er~(3+) doping concentration range 0.1-1.5 mol%, Er~(3+) first arrived at ~4F_(7/2) energy level by excited state absorption, then rapidly relaxed to ~2H_(11/2) and ~4S_(3/2) energy levels, the population of which increased, the remarkable upconversion green emission was obtained when Er~(3+) directly went back to ground state by radiative transition.

Er~(3+)浓度在0.1-1.5 mol％时，Er~(3+)通过激发态吸收跃迁到~4F_(7／2)能级，后迅速无辐射弛豫到~2H_(11／2)、~4S_(3／2)能级，~2H_(11／2)和~4S_(3／2)能级上Er~(3+)的布居数增多，Er~(3+)直接辐射跃迁回基态，上转换发射以绿光为主。

Berry ovoid or ellipsoid, apex different in texture from base, exocarp smooth, explosively dehiscent at maturity.

Beijingensis under three droughttreatments, normal, moderate and severe stresses. The results showed:(1) the canker disease ofboth cultivars was serious gradually with increased drought;(2) the bark tissue cells sufferedplasmolysis, more evident with the severity of drought stress;(3) under the drought andinoculation with B. dothidea, cells of two cultivars damaged at different degree, mailyrepresented in the changes of organelles, such as chloroplast swollen and distorted, number ofmitochondria increased and membrane system indistinct; then organelles suffered furtherdamagement with inoculation time, thinned mitochondrias stroma, decreased cristae, crumpledand partly broken membrane of chloroplasts with stroma exosmosis. At last, the chloroplastspartly disorganized;(4) the hyphae growed mainly intercellular in resistant cultivar and notonly intercellular but also intracellular in susceptible cultivar, which directly caused thenecrosis of cells;(5) under the severe drought, the damage of cells enhanced the infection ofpathogen and drought and pathogen stressed together and promoted the disease development;the damage from pathogen on cells was more serious than that from drought.

结果显示：(1)随着干旱胁迫程度的增加，2种杨树溃疡病害发生渐趋严重；(2)干旱胁迫下，杨树树皮组织细胞发生质壁分离，并随胁迫程度的增加而严重；(3)干旱胁迫下接种病原菌，2种杨树细胞发生不同程度的损伤，主要表现为细胞器发生较大变化，如出现叶绿体肿胀变形、线粒体数量增多，质膜模糊不清等现象；随接种时间的延长，细胞器受到进一步损伤，叶绿体被膜折皱，严重时局部破裂，基质外渗，并部分最终解体；(4)毛白杨中的菌丝主要在细胞间隙中穿行，而北京杨的菌丝除在细胞间隙中生长之外，侵入细胞内部也较多，直接导致细胞的解体；(5)干旱胁迫下细胞的损伤促进了病原菌的侵染，干旱和病原菌的双重胁迫加剧了病害的发生程度，并且病原菌侵染对细胞的破坏程度大于水分胁迫。

Iam not a good explainer but i will try to answer ur question.been a light, life and the truth simply means to have the base standard of Jesus's teaching that is tolove and to make others fill joy when meeting and talking with you.

荫不是好解说，但我会尽量回答乌尔question.been轻真理就是生命、有水准耶稣基的教学，使即tolove填补别人时，喜悦与你谈。

The one-dimensional time-dependent Schrdinger equation was numerically solved with the symmetric splitting of the short-time exponential propagator and the fast Fourier transformation, and influence of intensity and pulse with on ionization of linear multi-ation molecular ion in two-color laser fields was researched.

利用短时指数传播子对称分割法和快速傅里叶变换技术，数值求解了一维含时Schrodinger方程，探讨了双色激光场中激光的基波和谐波强度之间的不同配比以及脉宽对线性多原子分子离子电离的影响。

After that , he had some ideas of Fabianism in his mind : the top priority task of China's revolution was anti-imperialist and anti-feudal , patriotism and democratism were needed , the socialist system could not be implemented gradually until after the victory of the democratic revolution setting up the diversified forms of ownership on the economic system implementing the cabinet system of responsibility in government organization practising a single system in relation between the central government and the local government the democratic revolution should be led by the intellectuals of the petty bourgeoisie and capitalist class .

在英国师从拉斯基对费边社会主义理论进行研究之后，王造时形成了一些费边社会主义式的想法：中国革命的当务之急是反帝反封建，需要的是爱国主义和民主主义，待民主革命成功后，才能逐渐实施社会主义；经济制度上，建立多种形式的所有制；在政府组织方面，实行责任内阁制；在中央政府和地方政府的关系方面，实行单一制；应该由小资产阶级和资产阶级的知识分子来领导民主革命。

Finally, based on the characteristics of transient responses and the Morlet wavelet, a family of wavelet functions is introduced and used in the simulation of modal analysis.

文中分析了在众多小波基函数中Morlet小波更适合对动态结构系统进行模态分析的原因，结合Morlet小波的性质和结构系统对脉冲响应信号的特性，构造了一小波族，实现了利用Morlet小波变换对多自由度系统进行模态解耦和对时变系统进行模态参数辨识的方法。
