The steps for preparing insecticide include: first shaking flask for fermentation, adding amidon, soya bean cake powder, cotton cake powder, protease leather, yeast powder, maize milk, magnesium sulfate heptahydrate, monobasic potassium phosphate, dibasic potassium phosphate, calcium carbonate alpha-amylase and make-up water by ratio in culture medium with 100 unit volumes; secondarily filling 100ml culture mediums in triangular bottle, then seeding BTH-13 after disinfection and culturing them until the brood-cell pulls off under finite temperature; third adopting the selected culture medium and fermenting them in full-automatic fermentation tank, acidifying the fermentation liquor after the fermentation, adding the emulsifier, and directly performing spray-drying after the compression of the fermentation liquor to prepare the wettable powder.

制备杀虫剂的步骤是：首先是摇瓶发酵，在100单位体积的培养基中，按比例加入淀粉、豆饼粉、棉饼子粉、蛋白胨、酵母粉、玉米浆、七水硫酸镁、磷酸二氢钾、磷酸氢二钾、碳酸钙、及α-淀粉酶，补充水；其次是在三角瓶中装100ml培养基，灭菌后接种BTH-13，在一定温度培养至芽孢脱落；第三是采用筛选出来的培养基，在全自动发酵罐中进行发酵，发酵结束后发酵液酸化，加入乳化剂，酵液浓缩后直接喷雾干燥制备可湿性粉剂。

Among the three dimensions of triangles, the cross-generational coalition was negatively associated with marital satisfaction.

研究结果发现：(1)夫妻婚姻满意程度愈高，子女愈不会在父母争吵时涉入三角关系。

Children with divorced parents reported more cross-generational coalition than those with married parents, whereas children with married parents involved more parentification than children from divorced families.

进一步分析发现，夫妻婚姻满意程度愈低，子女愈容易在父母争吵时以「跨世代联盟」的方式涉入三角关系。(2)父母已离婚之子女比父母未离婚之子女更容易与父母一方联盟，而父母未离婚之子女则比父母已离婚之子女更容易有亲职化的表现。
