不精确地

A robust adaptive control scheme was proposed for a class of nonlinear systems in the presence of unknown parameters and unmodeled dynamics. The whole design was divided into two steps.

针对一类含有不确定参数和未知扰动的非线性系统，提出一种鲁棒自适应控制方法以确保系统输出稳定地精确跟踪给定的参考信号。

Based on this method, simulation results show that the closed-loop mobile robot system has not only the robust stability but also the perfect robust performance of tracking. The proposal of this method vanquishes the shortcomings of other methods designing controllers only for exact models, which can not ensure the system′s performance under internal perturbation.

仿真结果表明，基于此方法设计的控制器能保证移动机器人闭环系统不但具有鲁棒稳定性而且能很好地跟踪给定轨迹，具有鲁棒性能，从而克服了其他学者仅对系统精确模型设计控制器而导致系统出现内部摄动时，不能保证系统性能的缺陷。

The SeaWiFS will be the first ocean color satellite to follow the Nimbus-7 Coastal Zone Color Scanner, which ceased sending dataa in 1986 after more than seven years of operation.

宽视场海洋观测传感器是继工作了七年多，于1985年停止发送资料的Nimbus－7海岸带水色扫描仪之后的第一个星载海洋水色传感器，不像作为概念验证性实验的海岸带水色扫描仪那样，宽视场海洋观测传感器被设计用来提供充分精确的光合色素浓度资料以进行海洋初级生产力和生物地球化学定量研究［4］。宽视场海洋观测传感器将常规地每二日一次提供全球复盖资料。

Injection pump is as pressurized structure in the pressure feed system. Unloading valve can adjust system pressure. The method calculates strength with accuracy without limit of shape of basal body and magnitude of intensity.

该测量装置不仅能精确定量测定金刚石涂层的附着强度，而且测量范围不受基体形状及附着强度大小的限制，可方便地用于复杂形状基体金刚石涂层的附着强度测量，因而具有显著的经济效益。

The new watershed-based method which improves on the original watershed transform to some extent,can overcome the shortcoming of some conventional methods that they cannot mark the grain exactly and give a exact boundary or mark to every grain in the image.

在对颗粒分析方法进行归类和总结的基础上，提出了一种基于分水岭的彩色图像颗粒分析普遍框架，该框架不仅消除了有些传统方法不能进行颗粒定位的缺点，而且对分水岭算法进行了一定的改进，由于该算法对颗粒形状进行了精确定位，从而得到颗粒的各种特征信息，可比较好地完成了颗粒分析。

On both sides of the head, bo palletizer gables and jump out after all, coping with brick and WaiHu bolts into the curve, delicate and elegant, In front of the hall YanXia is WangZhuan grinding and Chuan bent with very precise porch corridor, look up, its monumental made by artificial and materials that, And the bridge of short column and column, is not a simple shu to use a few short wood, but installation high-relief curving flowers.the curving flowers and leaves, Lu carved into a cloud, LiangYun fog, not only can satisfy the structural component of the requirements, and the proper decoration, try and do not provide craftsmanship.

两侧山墙的垛头、博缝及后檐出跳，也都用砖磨成道道内、外弧的曲线，精致而又素雅；厅屋前檐下是把望砖磨成与弯椽配合得极为精确的轩廊，抬头望去令人赞叹不已，其制作所耗费的人工和材料可想而知；还有那梁架上的短柱与蜀柱部位，不是简单地用几根短木，而是安装高浮雕和透雕雕刻成荷叶墩、栌斗、山雾云、抱梁云构件，不仅能满足结构上的要求，又恰到好处的进行了装饰，真可谓两全齐美，别具匠心。

The possible thin wearing course thickness enables the economical use of high-value mineral nutrients regarding to polishing-resistance, elucidation and edge strength.

橡胶垫形式的履带保证摊铺机在施工中能充分补偿地面的水平不平整，实现精确的电子转向控制，保证良好的摊铺效果。

Carefully screw the tap to the precise line between one speed and a slower one, and the pattern refuses to stay on the edge but reverts to one state or the other, as if it were attracted to a side, any side.

小心翼翼地将水龙头调至过快和过慢之间的精确位置上，但这种模式不愿停留在那里，而是回复到一种或另一种状态上，仿佛它是被吸引到一边，任何一边。

Carefully screw the tap to the precise line between one speed and a slower one, and the pattern refuses to stay on the edge but reverts to one state or the other, as if it were attracted to a side, any side.

即使小心翼翼地将水龙头调至过快和过慢之间的精确位置上，这种模式仍然不愿停留在那里，而是回复到一种或另一种状态上，仿佛它是被吸引到了一边，任何一边。

Naturalism and realism to portray the same emphasis on the objective reality of the accurate picture of life, but the difference is that the tendency should be realistic and the plot from the scene revealed to naturally, it should not be pointing out in particular, while natural Literature and the fundamental negative should be subject to a certain degree of political and moral purpose, that literature should be to maintain absolute neutrality and objectivity.

自然主义与现实主义一样偏重于描绘客观现实生活的精确的图画，但不同的是，现实主义认为倾向应当从场面和情节中自然而然地流露出来，不应当特别把它指点出来，而自然主义则根本否定文学应当服从于一定的政治的和道德的目的，认为文学应当保持绝对的中立和客观。
