The analysis of AL, especially ALL aneuploid, by image analysis system can be helpful in distinguishing the high risk ALL from the standard risk ALL ,and the determination of cell cycle distribution can provide a crucial reference data for chemotherapy.

图像分析系统对AL尤其是ALL异倍体的分析，有利于判断高危ALL，对细胞周期的测定给化疗个体化提供了具体的参考指标。

Integrated with the design and the programming practice of the matching algorithms about LS MPP embedded computer used to image comprehension, this paper will analyze and study five problems about the SIMD computer which oriented to the application of image comprehension, they are how to reduce the number of memory instructions and their execute cycles, how many control register we require, how to protect the contents of the base address register, how to design the buffer and how to set up the date types of image array, etc.

本文结合 L S MPP嵌入式计算机图象匹配算法的设计与编程实践，对面向图象理解应用的 SIMD计算机减少存储类指令及其执行周期、控制寄存器的数量需求、基地址控制寄存器内容的保护、缓冲器的有关设计及图象阵列数据类型的设立等设计问题进行了分析和讨论，提出的一些设计思想对于面向图象理解的类似 SIMD计算机的设计具有较为重要的参考价值

Biomimetic laminated composite was fabricated by mimicking the cyclical matrix control process to form the highly structured Mollusca nacre, the structure and growth period of the biomimetic laminated obtained was similar to Mollusca nacre, it can be considered as a model for the research of the formation of Mollusca nacre.

获得的该复合材料与珍珠的结构和生长周期与珍珠具有一定的相似性，为研究珍珠的形成过程提供了参考模型，并通过研究珍珠的形成过程，掌握和了解珍珠形成的各种影响因素。

Chapter4 presentsthe calculation of optimal order quantity of single period inventory system of autonomous recovery problem based on the traditional "news vendor problem". And also analyses an example.

第四章在参考传统的报童问题的基础上，提出了自治复原的库存问题中单周期库存的最佳经济订货量的确定方法，并分析了一个实例。

Chapter4 presents the calculation of optimal order quantity of single period inventory system of autonomous recovery problem based on the traditional """"news vendor problem"""". And also analyses an example.

第四章在参考传统的报童问题的基础上，提出了自治复原的库存问题中单周期库存的最佳经济订货量的确定方法，并分析了一个实例。

Phenomena such as precession the slow roughly 25 000 year cycle of movement of the direction of the Earth's axis and nutation the continual "nodding" of the Earth's axis due mainly to tidal forces from the Sun and Moon all have to be taken into account when defining a Universal Reference frame.

现象，如进动，慢，大约25 000年的周期，对地球的轴的方向运动，章动，不断"点头"地球的轴心，这主要是由于来自太阳和月亮，所有潮汐力量要考虑到当定义一个通用参考框架。

Comparison between the numerical results in earth orbit and that in lunar orbit shows the characteristics of the periodic distribution for thermal parameters of the solar array in lunar orbit, which will provide powerful references for the design of the solar array and the whole lunar satellite.

计算结果与地球卫星的相应数据进行比较，明确了月球轨道上电池阵所得外热流以及温度的周期分布特点，为月球卫星上太阳电池阵以及整个卫星的设计提供了有利的数据参考。

For the purpose of reusing the developing experiment and knowledge of the existed successful complex large-scale system, the generation dimension of the modeling structure defines three case referenced levels of different generation, and builds up the reifying and extractive relationship. At the same time, method for building referenced model is presented, which is a kind of knowledge expression based on the case superset.

是当今对复杂大系统全生命周期各开发阶段设计工作支持最全面的一套完整的方法体系；为了充分利用已有的复杂大系统开发经验和知识，该建模框架的通用性维方向定义了参考案例的三个不同通用程度的案例参考层次，建立了各通用层之间的具体化和抽取关系。

Because the additional reference signal is not necessary, the delayed time is not related to the period of UPO and should not be the integral multiple of the period of UPO, so the presented method is simple and easy to apply.

由于不需要外加参考信号，延迟时间与UPO的周期无关，不必是UPO周期的整数倍，所以该方法简单易行。转载于论文联盟 http：//www.lwlm.cn
