查询词典 geometrical optics

We have asked that all of the air hoses be switched from polycarbonate to polyurethane. This is because polycarbonates outgas hydro carbons, which contaminate the air mixture reducing power, and can also produce H20 which can damage the optics.

我们已经要求将所有空气软管从聚碳酸酯换成聚亚安酯，因为聚碳酸酯会和混合气体中的碳原子产品反应，这们会使混合气体所产品的激光功率下降，同时会生成H20原子损坏聚焦镜。

高斯光束|高斯光束传播是近轴光学的扩展，它可以更为精确地描述相干传播

At this point, with a limited degree of familiarity with paraxial optics, and believing that only lens designers with a penchant for algebra can understand the subject, the vast majority of students opt out.

这种情况下，学生仅仅熟悉了一点近轴光学的知识，然后就是胡思乱想的假设只有嗜好代数运算的镜头设计专家才可以懂这一门学问，最后，大部分学生选择了放弃努力。

Coming with the multimedia era and fiber optics, the demand on optic fiber patch cord are soaring both quantity and quality.

由於光纤宽带时代的来临，所以对於光纤连接器数量及品质的需求不断的提高，但对於投入生产光纤连接器的厂商而言，却面临价格不断下降的压力。

We examined 8 cases after costal cartilage autograft in clinical observation through optics microscope, verified that the framework keeps the nature of costal cartilage and pointed out the importance of prevention of infection. Ear reconstruction can be completed in preschool age because we observed that the reconstructed ear in preschool age could grow with the normal ear in pace (7 cases). With perichondrium costal cartilage autograft could live and grow better.

临床观察8例肋软骨移植后的组织学检查，证实了耳支架成活后保持了肋软骨的生物学特性；强调了预防感染对移植耳支架的转归及治疗效果的重要性；观察到7例学龄前儿童自体肋软骨移植后再造耳廓能随年龄同步按比例生长，表明耳廓再造可在学龄前6岁时完成。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
