Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.
结果发现:棉铃虫卵在棉株不同部位的分布差异较大,2代棉铃虫卵主要分布在叶正面、叶背面和茎尖,3代棉铃虫卵主要分布于蕾铃;在放蜂田,赤眼蜂对棉株不同部位棉铃虫卵的寄生率差异较大,2,3代棉铃虫时期对叶正面、叫背面、茎尖、蕾铃的棉铃虫卵寄生率均较高,对叶柄和茎杆处卵的寄生率较低;并以3代棉铃虫时期的寄生率较高;在2,3代棉铃虫时期分别连续释放3次赤眼蜂,对棉铃虫具有很强控制作用,2,3代棉铃虫卵的被寄生率分别为66.0%~70.7%和76.0%~81.2%,均显著高于化防田的自然寄生率(2代:7.0%~12.3%,3代:5.2%~7.4%);蕾铃被害率分别为2.2%和3.1%,均显著低于化防田(2代:8.5%,3代:20.9%;2代棉铃虫时期,放蜂田和化防田的棉铃虫卵量和幼虫数量差异均不显著,但3代棉铃虫以后,放蜂田棉铃虫卵量和幼虫数量均显著低于化防田,且放蜂田的捕食性天敌数量显著高于化防田。

By summarizing the community factors, like theory determination, vanguard exploration and the photography community and so on, and taking a few key words, such as the time conception, the representative personage and their works, the esthetics pursuance etc, as standard, we can separate the sixth generation from such names as the cainozoic generation and the past-fifth generation out, and fix the basic points of the thesis.The esthetics pursuance of the sixth generation is the emphasis of the thesis, mainly incarnating the innovation of their theme selection, narrative strategy and image style, In the aspect of the theme selection, the sixth generation exhibits the metropolis fragment and the autoecious person through angles of the modern rock-and-roll, the city feeling and the fringe citizen, avoiding the theme of the fifth generation and the traditional film esthetics points, pays attention to the sub-culture of city.

Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.
作者给出了Canny算子与中心B样条二进小波严格的比较证明,得出如下结论:a中心B样条函数具有紧支集,Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数,中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求,并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143%。f中心B样条函数的导数可以构成稳定的二进小波,存在快速的多尺度算法;而Canny算子不构成稳定的二进小波,无法给出快速的多尺度算法。

The problem of multi-objective usually meet many conflict each other and can not use the objective of the same standard unit, then to employ membership function of fuzzy theory,at first each objective function to change fuzzy set and express with membership function, membership function include the maximum constraint, minimum constraint, the decrease function of monotonic property, to become optimal of the multi-objective function, but still to scanty of weighting value with regard to adjustment of objective function, thus this thesis proposes the method of combine orthogonal arrays and particle swarm optimization to solve the problem of multi-objective optimal power flow, each objective function separately add weighting value, to setting each weighting value of objective function in order to the result of anticipating.
多目标最佳化的问题通常会面临到许多互相冲突且不能用同ㄧ标准单位的目标,於是利用模糊理论中的归属函数,首先将各目标函数转换成模糊集合并以归属函数表示,归属函数包含了最大限制值、最小限制值、单调的递减函数所组成,将各目标函数利用归属函数表示,形成单一目标函数的最佳化,但是仍缺乏权重值对於目标函数的调整,於是本篇论文提出ㄧ种权重值设定与粒子群优演算法的方法去解决多目标最佳电力潮流的问题,将各目标函上分别加上权重值设定各目标函数的权重值,得到预期的效果。
