In this paper, we report the calculation of single line-image and double lineimage for various configuration of diffractive optical element, which were designed as one- dimensional plane configuration of bar- shaped pure- phase from the principle of the optical equal- path compensation.

报道以一维平面阶梯条形纯位相结构，用等光程补偿的物理概念出发，计算了单线与双线象的衍射光学元件的多种构形，获得了与理想衍射线象符合的光强分布；同时发现双线象时会出现噪音光强小峰，这在精确成象时仍是要设法避免的。

The measurement takes account of accumulation of discrepancy signals, distribution of discrepancy signals, and treatment of preternatural discrepancy signals. Based on the measurement, this paper presents, at the same time, a new algorithm for extracting features with symmetric figure on scanned topographic map.

前者匹配效率高，稳定性好，对图象的非本质的变化不敏感；而后者利用图象中的所有信息，所以区分不同图象的能力强，精度高，特别是它能在十分复杂的图象环境下(此时很难甚至不可能使用特征匹配法)有效地工作。

Motivated by these researches, the thesis proposes an original paradigm that implements IBMR in wavelet domain. In general, IBMR means performing a set of operations in image space, such as warping, correspondence searching, mosaicking, interpolation, and so on.

通常意义下的IBMR是在图象空间中完成一系列的变换、对应匹配、拼合、插值等操作，这些操作的复杂度不仅跟图象分辨率有关，往往还与计算象素的邻域大小、图象中的特征多少、参考图象的多少等因素有关。

Firstly, B-scan ultrasound images are captured form patients and the regions of interest are localized. During the feature extraction approach, three models are employed including mean intensity ratio of the near field and the far field, the gray level co-occurrence matrices and the gray level run-length matrices. 10 statistics are extracted from the three models for each image.

首先以脂肪肝B超图象纹理的变化为出发点，分别采集人体肝脏的B超图象，并选择图象中的感兴趣区域，计算出每一幅图象的近远场灰度比特征、灰度共生矩阵和灰度游程矩阵的二次统计量特征。

In our research, marked autologous fluorescent blood red cell is immitted into SD-rat body and the whole process is shown and recorded by microscope image system.

利用做过荧光标记的自身红细胞注入SD大鼠体内，通过显微图象系统将整个过程以视频信号的形式存贮，然后利用基于视频图象的采集卡，将流速变化过程回放采样，得到暗视场下的荧光图象，利用图象分析和处理的方法，测定血流速度。

It offers a more precise way for image analysis than wavelet multi-resolution analysis. Through merging images data of different wavebands from multi-sensor to the same object and different resolution images data by applying image fusion method based on wavelet packet analysis, we get fused pictures.

利用此融合算法将由多传感器获得的同一目标不同波段的遥感图象和不同分辨率的遥感图象进行融合后得到的融合图象，能够很好地将源图象的细节融合在一起。

Fifthly, the conception and the method of image compress is dissertated, also discusses the conception of wavelet transformation、continuous wavelet、discrete wavelet and multi-resolution analyses、Mallat algorithm, and do further research on the characteristic of wavelet images、the choice of wavelet bases and the continuation of image border, and based on this work, the way of freight train images compression combined with the wavelet and JPEG is put forward.

第五，论述了图象压缩的概念、方法，对小波变换的概念、连续小波、离散小波以及多分辨率分析、Mallat算法进行了讨论，并对小波图象的特点、小波基的选择以及图象边界的拓延进行了深入研究，在此基础上提出了小波和JPEG相结合的货车图象压缩方案。

We determined net male genetic effects on female and offspring fitness in a seed beetle and then tested whether fertilization success was biased in favor of high-quality male genotypes in double mating experiments.

研究人员惊奇地发现，当雌性豆象与2个雄性豆象交配的时候，那个&低品质&的雄性豆象的精子会比&高品质&豆象育出更多的后代（用仅交配一次后所产生的后代的数量来衡量）。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
