In this algorithm, inertia weight is nonlinearly adjusted by using population diversity information. Velocity mutation factor and position interchange factor are both introduced and the global performance is clearly improved. The algorithm has been applied to optimization of parameters in SVM.

该算法利用种群多样性信息对惯性权重进行非线性的调整，并在算法的后期引入速度变异算子和交换算子，使算法摆脱后期易于陷入局部最优点的束缚，同时又保持前期搜索速度快的特性。

The first part discusses about the effects of the five factors:temperature,relative air moisture,rate of frass sifting,density of larvae,fodder water percentage to growth speed and survival rate of older mealworm (Tenebrio molitor L.) larvae through rotational composite design of quadratic regression. Two models were established to describe the effects of the five factors. The models showed that percentage of fodder water is the major factor that has effect on the growing speed of T. molitor larvae,and fodder water is the major factor on death rate. The models also show that temperature on growth speed,temperature and fodder have important effects on death rate,and the significant test showed they have significant difference on 1% or 5% level. From the two models,by frequency analysis,we can get the optimizing rearing condition,in which the mealworm larvae overweight 10% per day,temperature is 25-26 ,frass sifting rate is once 2-4 days,density of larvae is 0.61-0.79 g/cm2,fodder water is 33.27%-39.71%. And the rearing condition,in which total death rate of T.

第一部分：采用五因素二次正交旋转组合设计，以黄粉虫幼虫饲养过程中饲养温度(X_1)相对湿度(X_2)、虫粪筛除频率(X_3)、饲养密度(X_4)以及饲料含水量(X_5)五因素为参试因素，考查它们对黄粉虫高龄幼虫的生长及存活的影响，建立了以黄粉虫幼虫增重率及死亡率为目标函数的回归模型，并进行了简化： Y_增=127.5079+18.6559x_5+2.7894x_3x_4-2.3854x_3x_5-3.0594x_1~2+1.8241x_3~2-3.8559x_5~2 Y_死=1.7459+0.4108x_1+0.0975x_2+0.9025x_4+0.3442x_5+0.0834x_1~2+0.3060x_4~2-0.2623x_5~2 分析结果表明：影响黄粉虫幼虫生长后期增重及死亡的主要因素分别为饲料含水量和饲养密度；饲料含水量和温度对黄粉虫增重有着重要的影响，饲养密度、温度、饲料含水量对黄粉虫的死亡有着重要的影响，其影响均达1％或5％显著水平；黄粉虫幼虫后期日增重率大于10％的饲养条件为：温度26～27℃、筛粪频率2～4天／次、饲养密度0.61～0.79g／cm~2、饲料含水量33.27～39.71％。

According to making research on its deconstructing subject in the traditional philosophy, We can get a more profound understanding about the relationship between his philosophy and the traditional philosophy Wittgensteinian deconstructing mainly embodies the following points; firstly ,he unloaded magic halation of "self",according to researching 'self'; secondly , he removed the duality of subject .thirdly, he discarded introspection belonging to the subject.

后期维特根斯坦的哲学是以彻底反传统著称的，通过对后期维特根斯坦哲学对传统哲学中的"主体"的消解，我们能更深刻地理解他的哲学与传统哲学之间的关系。维特根斯坦的消解主要体现在三个方面：（1）通过对"我"的考察，卸掉了"我"身上的神秘光环；（2）解除了主体身份的二重性；（3）抛弃了主体的反思功能。

The activity of catalase in rind of both hybrid and inbreed showed the trend of decreasing, but increased in early period and decreased later in four season pummelo, while in inbreed pummelo pulp it showed the trend of decreasing, but increased in early period and decreased later in hybrid and four season pummelo.

自交和杂交琯溪蜜柚果皮中的过氧化氢酶活性呈下降的趋势，四季柚前期上升，后期下降；而果肉中的CAT活性变化是自交琯溪蜜柚呈下降趋势，杂交琯溪蜜柚和四季柚前期上升，后期下降。

W7 was added when the cells entered anaphase, we found that although some cells had elongated, the distribution patternof CaM at central spindle was normal, and it seemed that a cleavage furrow would possibly form soon, however, these cells stopped cytokinesis at this stage, no furrow ingression followed.

本实验中我们还观察到在胞质分裂后期，CaM与Y一微管蛋白共分布于中体两端。W7处理同步化在胞质分裂后期的细胞，不但使中体解聚发生延迟，而且抑制了Y一微管蛋白与中体的解离。

然而省际人口迁移现象是人们对特定时期省区间差异的一种反应，不同的时期必然会表现出不同的特征与规律。2000年的全国第五次人口普查为我们研究90年代后期的省际人口迁移提供了可靠的数据支持，本文正是在这样的基础上展开了对90年代后期我国省际人口迁移的研究。

A student of Lowell and also an admirer of Jarrell, Snodgrass exemplifies the post-formalist as well as the Post-Romantic trend toward individual expression, neither academic nor Beat.

斯诺德格拉斯是洛厄尔的信徒，也是贾雷尔的崇拜者。他是一个例子，说明了后期形式主义和后期浪漫主义倾向于表现个人，即不是学院派，也不是垮掉派。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。
