The proportion of the viruliferous Laodelphax striatellus is the most important factor for the epidemic of the disease, so a rapid and sensitive method is necessary for detection of RSV in Laodelphax striatellus.

灰飞虱的带毒虫量是条纹叶枯病发生流行的主要影响因子，因此建立一种快速、灵敏检测灰飞虱带毒率的方法是迫切需要的。

Indirect ELISA was then used for detection of RSV in Laodelphax striatellus Fallen. The proportion of the viruliferous Laodelphax striatellus in Jiangsu province ranged from 12.5% to 41.5%.

The average gray of normal skin and vitiliginous lesion was approximation.

结果20例白癜风患者的28块皮损进行了自体黑素细胞培养移植，移植后的平均灰度与正常皮肤平均灰度接近。

There is a large amount of ash after coals combustion, which results that the heat-exchanger is abraded in the tail flue of the boilers in the power plant, further more, results in a great deal of the safety problems and the economy loss.

在火力发电厂中，煤燃烧后形成的烟气中含有大量飞灰，灰粒通常保持固体状态，对于锅炉尾部烟道中的受热面带来了很严重的磨损，从而造成了大量的安全问题和经济损失。

Eight 3×3 Kirsch direction templates are convoluted with a SAR image respectively and the maximum of convoluting results is used as the edge strength value of the central pixel in the window. The output gray level of the central pixel is the weighted average of gray levels of its eight neighboring pixels, and the weighting coefficients are corresponding edge strength values.

该方法利用8个3×3的Kirsch方向模板分别与SAR图像进行卷积运算，取其中的最大值作为窗口中心像素的边缘强度值，中心像素灰度值的滤波输出为它的8个邻域像素灰度值的加权平均，加权系数为每个像素的边缘强度值。

In a method and an arrangement for processing a skin print image, and particularly a fingerprint image, which image exists as a gray-level image, provision is made for the gray-level image to be convolved in the direction of two axes by generalized gradient filters, for the generalized gradients obtained in this way to be normalized, for the normalized, generalized gradients each to be convolved with generalized gradient filters, and for the sum of the two results of the convolution of the normalized, generalized gradients to be converted to binary form.

在处理皮肤印迹图像的方法和设备中，具体来说，处理指纹图像的方法和设备中，指纹图像是作为灰度级图像存在的，对于灰度级图像进行如下的规定：通过通用梯度滤波器沿两个轴的方向卷积灰度级图像，归一化以这种方式获得的通用梯度，利用通用梯度滤波器卷积每一个归一化的、通用梯度，并且转换归一化的、通用梯度的卷积的两个结果之和为二进制形式。

The results were as follows: Compared with natural growth, defoliating and shielding photosynthesis organs decreased the contents of starch, fat and iron in wheat grains and yields of starch, fat, protein, ash, phosphorus, potassium, zinc, iron and calcium in a single ear.

结果表明，剪叶遮光后小麦籽粒中淀粉、脂肪、铁含量比正常生长降低，灰分、磷、钾、锌、钙含量提高，而对蛋白质含量影响很小；剪叶遮光后小麦籽粒淀粉、脂肪、蛋白质、灰分、磷、钾、锌、铁、钙单穗产量均比正常生长降低。

You are that glass of dirtied water, gray faced all day.

She still stood at her post , her flushed and perspiring face coated with the corn - dust , and her white bonnet embrowned by it

苔丝仍然站在她的位置上，累得通红和满是汗水的脸上落了一层麦灰，白色的帽子也被麦灰染成了黄褐色。

The valid gray grads are equipoised. This algorithm conquers the gray discontinuity and drop. This algorithm has achieved the elimination of gray redundancy and the improvement of image quality.

该算法在压缩灰度冗余的同时，进行直方图均衡，克服了传统直方图方法在图像增强时造成的灰度断层和丢失，提高了图像质量。
