First,the determinant is regarded as a function of or- der n and denoted by D;Second,the determinant is expanded by row or by column,then the relation in both of Dand subdeterminants will be examined in details to set up certain a recursion,generally speaking,it must be a homogenous or a non homogenous recursion;fi- nally the coefficients of the general solution are found out with the aid.

给出了用递归关系方法求任意 n 阶行列式的值的一般方法：首先，把已知的 n 阶行列式看作为阶数 n 的一个函数，记为 D；其次，按行或按列展开这个行列式，并仔细观察存在于余子式及 D里的关系，建立关于 D的某一递归关系，此关系总为一个齐次的或非齐次的递归关系；最后，借助于 D(0)、D(1)和D(2)等求出递归关系的通解的系数。

对植物来说，很多组织缺乏正常的途径对D-氨基酸进行氧化脱氨基作用，由于这种消化系统的不同导致的结果是，有几种D-氨基酸本身对植物是有毒性的，即使在D-氨基酸相对浓度较低的情况下。

Results: Tyroserleutide can significantly increase the life span of H22 tumor-bearing mice by 50-70% in dosages of 20ug/kg/d-80ug/kg/d,specially the high dosage of 80ug/ml can significantly increase the life span by 69.24%; Tyroserleutide can inhibit the growth of transplanted hepatocellular tumor BEL-7402 in nude mice,the rate of tumor inhibition was25-50% in dosages of 40-320ug/ml ,the inhibition rate of 160ng/ml was 44.03%; Tyroserleutide could inhibit the growth of H22 and BEL-7402 tumor in a dose-dependent manner. Simultaneously, tumoricidal activity of tyroserleutide against BEL-7402 cell line in vitro was observed hinger when compared with the control group(P.05).The inhibition effect of 72hrs was higher than 24hrs,48hrs,96hrs.And specially the high dosage of 160ug/ml can significantly inhibit growth of tumor cell by 19.36%. Tyroserleutide can activated PEM and marked enhance cytotoxicity andphagocytosis functions in vitro and in vivo. The OD values of cytotoxicity were observed hinger when compared with the control group(P.05).The cytotoxicity of macrophages activated by tyroserleutide against BEL-7402 and B16-F10 was 35.58%,61.2% in vitro and21.39%,47.63% in vivo. The cytotoxicity rate of nude mice PEM was 32.86%,73.07% in vivo. Furthermore, tyroserleutide alone could stimulated the production of IL-1B TNF- a and NO by M . Tyroserleutide and LPS could synergistically activated M producing more cytotoxicity effectors. Conclusion: Tyroserleutide had inhibition functions against hepatoma carcinoma .Its possible mechanisms were related to the affect that Tyroserleutide could inhibit tumor cell directively and induce tumor cells apoptosis or death effectively.
