使渐变

Its main tasks are to deal with binary images, gray scale processing, and the use of Sobel, Canny, Roberts, Laplacan operator of four digital image edge detection, the results show that: Roberts operator more precise positioning, but more sensitive to noise, Sobel operator son of gray-scale images with low noise gradient has a better detection of the effect of Laplacian can be detected in the vast majority of the edge did not appear at the same time the basic pseudo-edge, the edge can be precisely targeted, Canny operator is the traditional first-order differential operator in one of the best operator to detect the best edge detection, edges clear, make clear at a glance.

主要工作包括图像的二值处理，灰度处理，并运用Sobel、Canny、Roberts、Laplacan四个算子实现数字图像边缘检测，结果表明：Roberts 算子定位比较精确，但对噪声比较敏感，Sobel算子对灰度渐变低噪声的图像有较好的检测效果，拉普拉斯算子可以检测出绝大部分边缘，同时基本没有出现伪边缘，可以精确定位边缘，Canny算子是传统一阶微分算子中最好的算子之一，检测边缘检测的效果最好，边缘轮廓清晰，使人一目了然。问题补充：摘要英文翻译，不要在线翻译的，是在线等！急啊！！！！谢谢！！！！

When the boxboards stay long in refrigerator in very low temperature, the waterproof level will decrease passing through along with the time which is because the humid air keeps permeate into the boxboards. The strength of the boxboard may become weaker. Consequently, cartons which are made of the boxboards can collapse more easily when they are stacked up.

但主要缺点为防水效果并非十分理想，湿气不断的侵蚀长期待在冷藏库里的低温下的纸板，使防水效果因时间的增加而逐渐变差，也使得纸板本身的强度变差，层层堆叠的纸箱容易因此倒塌。

This will give some depth to the color on our text instead of just a solid or gradient.

这将使一些深度在我们的文字颜色，而不只是在固体或渐变。

The epidemiology investigation showed that the morbidity and mortality of it is remaining increasing in recent years.

癌的渐变过程，使肺癌的早期诊断和早期治疗成为可能。

At the early iteratives, the mutation rate is bigger and the aim is to make particles to explore smaller and isolate region and to avoid the algorithm trapping to the local optimum. While the algorithm runs, the mutation rate will be decreased to reduce the disturbing to the particles. IPSO adopts a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space. Additionally, our algorithm incorporates a mechanism with a simple and easy penalty function based on the largest distance between the particle and the boundary of the feasible region to handle constraint.

IPSO采用了一种新型的变异策略，变异概率随着算法的运行是动态变化的：在算法运行初期，变异概率大，其目的是使算法不但能够探测到目标空间中的孤立区域，而且避免搜索陷入局部极值；在算法运行后期，变异概率逐渐变小，以减少对粒子的扰动；算法通过将部分具有邻近距离的粒子聚集成核形成多子群引导种群中粒子的飞行；采用一个简单的基于粒子与可行域边界最远距离的罚函数处理约束的机制，使得算法高效实现。

This would produce a large impact restoring force to straighten well-bore gradually.

这对井壁产生较大的冲击纠斜力，使井眼逐渐变直。

The results show that sulfite ion increases with pH value and concentration of sodium sulfite, which results in the increase of solubility of silver chloride. In the circular leaching solution, the solubility of silver chloride becomes lower with the increase of concentration of chloride ion.

结果表明：pH值的增大和亚硫酸钠浓度的提高，使与银配位的亚硫酸根离子增多，从而氯化银的溶解度明显提高；在亚硫酸钠循环浸出氯化银的过程中，溶液中不断积累的氯离子导致浸银效果逐渐变差。

The effect curve reflects the relationship between fertility factor and crop production, and the subordinative functions are got.

通过肥力因子与产量的效应曲线建立隶属函数，解决了模糊变量渐变过程中的定量化问题；引入层次分析结合专家知识确定肥力因子权重，更符合客观实际，使评价结果更准确。

The metasomatism resulted in decreasing content of orthopyroxene, increasing contents of clinopyroxene and olivine in peridotite, and the transformation from harzburgites to wehrlites.

这种交代导致橄榄岩中斜方辉石逐渐减少，单斜辉石和橄榄石逐渐增加，从而使方辉橄榄岩渐变成易剥橄榄岩。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
