This dissertation was designed to study heteto-phase grafting polymerization of vinyl acetate , maleic anhydride and VAC/MAH binary monomer system, irrespectively, with low density polyethylene film as substrate and benzophenone as photoinitiator. The purpose is to develop new and more effective methods to modify the surface and buck properties of polyolefines by studying the grafting mechanism of the system and exploring the characteristics of the grafting process.

本文主要以低密度聚乙烯膜为基体膜，以二苯甲酮为光引发剂，分别对醋酸乙烯酯、马来酸酐以及VAC/MAH的非均相接枝聚合反应进行了系统研究，以探讨相关的接枝反应机理、接枝反应过程以及接枝工艺的可行性，目的在于建立聚烯烃材料本体和表面改性新方法。

What's more, we also study some key techniques and realization difficulties of image authentication in-depth, including referent block to help tamper localizing, sign bit adjustment for binary encoding, mean quantization improvement, diagonally extension to help tamper localizing, and discard isolated error point to tolerate incidental distortion. These techniques can be used for good reference to the development of image authentication technique.

此外，我们还对数字图像鉴别的一些关键技术和实现难点进行了深入研究，主要包括有：参考点辅助定位技术、二值编码中的符号处理技术、均值量化方法的改进技术、对角扩展和去除孤立点技术等，这些技术的研究都对数字图像鉴别技术的发展具有很好的借鉴意义。

And a way to find the elements ofthat are conjugate to is proposed. Then we prove that the quotient group is isomorphic to, the symmetric group of order , and is a semidirect product group of with the classical binary simplex code in the linear case. Finally, we generalize a result due to Calderbank et al..

本文刻画了商群与集合的关系，给出了一个确定集合中那些与共轭的元素的方法，还证明了在线性情形下，商群与阶对称群是同构的，而且是与经典单形码的一个半直积，并且推关广了Calderbank等人的一个结果。

Isopiestic measurements are known to be one of the most accurate methods in determining thermodynamic properties for aqueous solutions and has been used mainly for binary and ternary unsaturated solutions.

等压法是测定溶液热力学性质的最精确的方法之一，前人主要用它测量二元和三元非饱和水溶液。

Therefore, in this paper, importing Genetic algorithm which has been applied successfully to deal with this problem, we present a better approach to compress a binary image by using Iterated Function System and Genetic Algorithm.

然而，IFS的求解属于NP-hard问题，在复杂的约束条件下，并要在庞大的搜索空间中寻求最优解，传统的搜索方法几乎是不可能的。

And "Huji" is also an medi-variable to put effect on education, which means that the binary social structure between city and country has still operated on job mobility of labor force.

本文还对调查中涉及的影响劳动力职业流动的个人主观因素如职业价值观和一些社会结构及行政因素进行了分析，以供政策参考。

Even though Kermit used an entirely binary system (open-closed-open-closed), you had no issues understanding him.

即使柯密使用了完全二进制系统，你没有问题的理解他。

However, laboratory and field experiments show that mosquitoes can produce binary toxin resistance under a long-term high selective pressure, which compromises Bs products as a biological mosquito larvicide in the comprehensive prevention and control of vectors and mosquitoes.

但实验室以及野外实验表明，蚊虫在长期高选择压力下能对二元毒素产生抗性，蚊虫对Bs产生的抗性影响了其作为生物杀蚊幼制剂在蚊虫综合防治中的持效应用。

Laser printers by laser, acousto-optic modulator, high-frequency drivers, scanners, desynchronizers and acoustooptic, etc., it is to interface circuits for the binary lattice information modulation in laser beam, scan-to-peripherin-seadweed.

激平打印机是由激平器、声平调制器、高频驱动、扫描器、同步器及平偏转器等构不败，其功用是把接口电路送来的二进制不面阵陈闻调制在激平束上，之后扫描到感平体上。

On the other hand, some marine animals (such as dolphin, whale, et al.) and plant leafage have the capability to resist the biofouling (namely, self-cleaning effect) because of their micro-nano-binary structure.

海豚、鲸鱼等大型海洋动物的皮肤和莲藕等植物的叶子由于具有类似于微相分离形态的纳米-微米级的双重结构，因而其自身具有极好的防污功能。
