在...的控制下

The Diels-Alder cycloadditions of [60] fullerene for preparation of optical limitingmaterials are discussed in chapter 3 and 6. Soluble cycloaddition derivatives of 〓aresynthesized by the reaction of 〓 with indene,1,1'-biindene andcyclopentadiene derivatives.〓Particular, the Diels-Alder cycloaddition of 〓 with1,1'-biindene under controlled conditions affords the stable monoadduct 〓〓of novel structure, which was confirmed by HPLC, FTIR, FD-MS,〓NMR,〓 NMR, HMQC and HMBC spectra, Its two bridgehead cage carbons resonate at70.91ppm, The 〓 NMR spectra showed 38 lines consistent with the 〓 symmetryassociated with [6,6] addition. The 〓 shows similar optical limitingproperties to that of 〓 in toluene for 8ns laser at wave length 532nm. Moreover, thehigh solubility of this adduct in polar solvents such as THF, acetone enables itsincorporation into sol-gel glass matrix. The thin films prepared via the sol-gel methodshow improved OL behaviour compared to those of 〓. The langmuir-Blodgett filmformation and uv-visible absorption of 〓 are also investigated. LBmonolayer of this compound is prepared on the air-water interface at 〓 mol/l. In chapter 4, three water-soluble derivatives of [60] fullerene: fullerol(1), theaddition product (2)of fullerol (1)with polyvinylpyrrolidone and fumaric acidderivative of 〓(3) are synthesized and characterized.

通过Diels-Alder环加成反应，用茚〓和1，1'-联茚〓及取代茂合成了一系列可溶性的〓环加成衍生物，发现可控制反应条件，使1，1'-联茚与〓反应，并高产率地得到具有新颖结构的单加成物，用HPLC、FTIR、FD-MS 及〓、HMQC、HMBC等多种波谱技术对其结构进行表征，测得它的两个〓杂化的桥头碳的化学位移为〓ppm，证明生成的衍生物为6∶6闭式环加成，〓NMR谱中共给出38个信号，表明〓联茚衍生物分子具有〓对称性；在波长532nm，脉冲宽度8ns的激光下，〓联茚衍生物的甲苯溶液的光限幅性能与〓的甲苯溶液相近，由于〓联茚单加成衍生物熱稳定性好，在四氢呋喃，丙酮等极性溶剂中溶解性好，能分别均匀地掺入溶胶-凝胶中，已发现它的溶胶(so1)光限幅性能优于纯〓的光限幅性能；使用Langmuir-Blodgett技术将〓联茚衍生物在空气和水的界面进行了LB单层膜和多层膜实验以及UV-Vis吸收谱研究，通过等温压缩曲线测试，证明浓度为〓〓时，〓联茚衍生物能够形成单层膜。

At the same time, We also face new challenges in inventory control.

在供应链管理的环境下，物流管理活动呈现出新的变化与特点，库存控制也面临着新的问题。

It is also used to select dBm or dB in the dB function; GPIB selects local or GPIB control; KEYLOCK locks the selected operation; RELATIVE sets up deviation measurements; HOLD holds the reading when pressed.

它也可以用来选择 dBm 时或分贝在分贝功能； GPIB 的，选择本地或 GPIB 的控制； keylock 锁选定操作；相对集了偏差测量；持有控股读时，按下。

At first, we present a necessary condition for the existence of optimal linear state feedback control by means of Lagrange multiplier theorem.

首先利用Lagrange multiplier定理得到了存在最优线性状态反馈解的必要条件，而在加强的条件下也得到了最优控制存在的充分条件。

By the analysis of dive and horizontal plane nonlinear model, the catastrophe model on de dive plane is deduced, and catastrophe stability is analysized. In the horizontal plane, simplified equation is gained by center manifold theory, then draws the conclusion that the stability of limit circle arises from critical point is relate to small difference of move point and critical point.

通过对潜艇垂直面和水平面非线性运动模型进行分析，导出垂直面运动的突变控制模型，并进行了突变稳定性分析；在水平面运动的非线性分析中，通过中心流形定理简化方程，得出临界点处极限环的稳定性与微差占的符号有关的结论，这样在无法或很难得到李亚普诺夫函数的情况下，可以通过这种方法判别临界点的稳定性。

This logical paradox proves that, institutionalization of freedom of press and economic freedom alone cannot guarantee the realization of the ideal goal of the liberalist theory. It is in this very paradoxical situation that related structural categories which influence journalism have, through struggle and compromise under the same mainstream ideology, caused the institutionalization of editing-management separation system and the underpinning journalism professionalism which protects the freedom of news production from market interferences, thus realizing to some degree the freedom of press.

逻辑悖论证明，仅仅有新闻自由、经济自由的正式制度，并不能达致自由主义报刊理论的理想目标；恰恰在此悖论中，影响新闻业的相关结构性范畴在共同的主流意识规约下经过博弈和妥协，达成编营分离制度安排以及作为编营分离制度支撑的新闻专业主义，阻抗了市场力量对新闻生产自由的控制，一定程度上确保了言论出版和新闻自由的实现。
