The key to feature extraction is to select the optimal feature combination from all the features. In this study, the optimal color feature combination,{/G,(R+4G+B)/6, H variance, S variance}, is selected using genetic neural network at first. Then the main texture features including the mean, variance, energy and entropy of the cooccurrence matrix, the secondary texture features including the maximum frequency number, absolute uniform, inertia and importance of the co-occurrence matrix are extracted.

在此基础上，提出适合多阈值和小目标图像分割的免疫遗传图像分割方法，该方法借鉴了生物免疫系统自调节、抗原识别和记忆功能，并结合了遗传算法对图像进行自适应区域的阈值分割，改善了遗传算法优化复杂问题时存在收敛速度慢和易陷于局部最优的不足，克服了传统阈值分割方法对目标大小的限制，是一种新型的有效的图像分割方法。

The kinetic behaviors of ethylene homo- olymerization and ethylene / l-hexene co-polymerization , catalyzed by the metallocene catalyst PS-DVB-MC in an 0.5 L stainless steel reactor , were studied. The effects of polymerization conditions on ethylene polymerization , such as concentration of catalyst , temperature of polymerization , pressure of ethylene , molar ratio of AI / Z r , etc ., were also investigated . Some leading results were as follows : the activity of the catalyst PS–DVB- MC for ethylene homo-polymerization was high ( 1.053 x 107 gPE / mol Zr·h ), but the molar ratio of AI / Zr was low ( 350:1 ); the catalytic ability for ethyleneα-olefin ( such as l hexene etc .) co-olymerization was great , and the corresponding activity come up to a maximum of 1.753 x 107 gPE / mol Zr·h while concenlration of l-hexene was 0.080 mol / L ; the molecular weight of polyethylene was about 180,000 , meanwhile the molecular weight distribution was narrow ( 2.19 ); the bulk density of polyethylene and ethylene / l-hexene co -polymer were 0.25 and 0.34 respectively .

采用0.5L高压不锈钢反应釜，对催化剂PS–DVB-MC催化乙烯均聚和乙烯/ l-己烯共聚合的动力学行为进行了研究，详细考察了催化剂浓度、反应温度、压力、Al/ Zr比、1-己烯浓度等因素对乙烯聚合反应的影响，得到如下主要结论：催化剂PS-DVB-MC具有催化乙烯均聚的高活性(1.053×107g PE / mo1 zr.hr)，低Al / Zr比( 350：1 )；具有良好的催化乙烯与α-烯烃(如1-己烯等)共聚的能力，在1-己烯浓度为0.080 mol / L时，催化活性达到最大(1.783×107 g PE / molZr.hr)；乙烯均聚产物的分子量在18万左右，分子量分布窄( 2.19 )。
