使成块状

In plantation management, APP GXFMC reserves buffer strip, sets up firebreak, plants trees of various species and clones. Plantation forms natural mixed forest in group with nearby indigenous forests. Plantation and surrounding environment compose a perfect ecosystem together. Thereby biodiversity is improved. And forest regulation and control capacity is enhanced. Forest capacity of prevention from disease and pest is increased, too.

APP广西林务在营林中，保留缓冲带、设置防火隔离带、种植不同的树种和不同品系的树林，与周边乡土林成自然块状混交，使人工林与周围环境形成了一个良好的生态系统，从而提高了生物多样性，提高了森林的自我调控能力，增强了森林自身抗御病虫害的能力。

The results showed that the structure characteristics of block cloddy was with tight surface but loose inner, the bulk density of the crust can be high as 1.39~2.0g/cm^3, which was mainly affect by unreasonable tillage process. The tight surface can not be crushed by nature alternation of drying and wetting. Farming machinery to impact and rotary tillage were necessary when reduce them.

结果表明不合理耕作所产生的块状结构体具有外部极为密实而内部相对疏松的构造特征，外壳的容重高达1.39~2.0g/立方公分以上，仅依赖于自然干湿交替作用使其碎散成小的土团成为不可能，必须运用机械击打、旋耕切割等方法进行破碎。

However, these rigid and dense carbonates and thick-bedded sandstones are of relatively developed secondary fractures and solutional pores, which are mainly distributed in four suites of rigid rocks.

然而对于刚性致密的碳酸盐岩以及厚层块状砂岩，次生裂隙、溶隙相对发育，它们分布于四套主要的刚性岩层中，极大地改善了这些岩石的孔渗性能，使之成为良好的裂隙储集体，为海相中生界、古生界油气聚集成藏提供了有利的储集空间。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
