The air velocity has little effect on the initial frost crystal shapes.
空气流速对初始霜晶形状的影响不大。
Most frost damage takes place at night. Ice crystal from on the leaf surface. They pull moisture from the leaves and keep plant tissues form getting water.
大多数霜冻灾害发生在夜里。冰晶来自叶子表面。他们从叶子和来自取水的保存植物组织析出水分。
On the basis of analyzing this image, it is found that the distribution of ice crystal at the initial period of frost growth is different from that at fully growth period.
通过对图像的分析，发现霜层的生长初期冰晶体的分布与充分生长的霜层有所不同，此时霜层靠近冷表面固含率最大；
Several parameters, such as frost height, solid holdup, quantity of ice crystal and distribution of ice crystal at different level and so on can be gotten by analyzing this binary image.
通过对二值图像的分析，可以得到霜层的高度、固含率、冰晶体沉积量以及冰晶体在不同高度的分布等参数。
Among the Imperial Egg Collection was the 1913 Winter Egg, carved from rock crystal and ornamented with platinum and diamonds to resemble frost.
其中一个系列是制作于1913年的“冬季彩蛋”，它由无色水晶雕刻而成，用白金和钻石点缀以呈现类似霜冻的景象。
