Based on the second- and fourth-order compact difference formulas for second-order derivatives and the idea of weighted average, two classes of the alternating direction implicit method are proposed for solving two-dimensional wave equation. The methods are of accuracy O (T^2+h^4) and O (T^4+h^4) respectively. Stability conditions are obtained by Fourier analysis method.

基于二阶微商的四阶紧致差商逼近公式及加权平均思想，提出了数值求解二维波动方程的2种精度分别为O(т^2+h^4)和O(т^4+h^4)的交替方向隐式格式，以及与其相匹配的第一个时间层的同阶离散格式，并且通过Foulier方法分析了格式的稳定性。

Antibacterial function of body wall was conducted by the following way: microorganism was directly resisted through the change of cuticle, such as incrassation of up-cuticle protuberance and increasing length of micro-floccus in the up-cuticle dissociation surface; exudation function of large granular orthochromatic mucous cells and reticulation mucous cells in the epidermis could be enhanced when the Eisenia fetida was induced by E. coli. Moreover, the mucus that contained compound substance of mucopolysaccharide and protein could make the bactericidal function or dilute the microorganism on the surface of earthworm, which could protect earthworm from invasion of microorganism; the content of neutral mucopolysaccharide of antibacterial function could be increased according with the exudation increment of small granular proteinaceous cells in the epidermis, which could resist bacteria invading into the epidermis of earthworm.

结果表明：蚯蚓的体壁主要是通过以下途径来抗细菌的侵袭：一是通过角质层的变化(如上胶层突起的增厚、上角层游离面中微绒毛的变长等)直接抵抗微生物的入侵；二是增加表皮中大颗粒粘液细胞和网状细胞的分泌功能，分泌出大量含有粘多糖蛋白液体复合物的粘液，在蚯蚓体表对细菌进行稀释或者起到直接杀菌的作用；三是通过增加小颗粒蛋白细胞的分泌作用，在蚯蚓的表皮中分泌出更多的抵抗疾病的中性粘多糖，从而抵抗进入蚯蚓体表内的细菌。
