For the problem that the suppression of co-channel interference and suppression of noise can't be balanced in signal-to-jamming and noise ratio maximization method for the linear precoding of multiuser multiple-input multiple-output downlink systems, an improved scheme that the term of noise variance is modified as a piecewise linear function is proposed, in which the balance between suppression of co-channel interference and suppression of noise can still be maintained even when the noise variance is a small value through piecewise modifying the term of noise variance, and thus the bit error rate and capacity of the systems are further improved.

针对多用户多输入多输出系统下行链路线性预编码的信干噪比最大化方法中，共信道干扰抑制和噪声抑制不能有效平衡的问题，提出将其中的噪声方差项修正为以噪声方差为变量的分段线性函数的改进方案。该方案通过对噪声方差项的分段修正，在噪声方差的值较小时依然能够保持共信道干扰抑制和噪声抑制间的平衡，从而使系统的误比特率性能和容量得到进一步提高。

Since in some instance, the variance of response variable might be changeable along withthe alteration of explanatory variable, in the procedure of model constructing, a fixedeffects model should be considered firstly, then the random effects model or randomcoefficient model when necessary.

Results: In acute experiment, there was no significant difference of body weight or organ indexes between the normal control and arsenic poisoning groups ; while the CH50 level, lymphocyte accruing rate, phagocytosis rate and macrophagocyte index in arsenic poisoning group were significantly lower (P.05 or P.01) than those in normal group. There was no significant difference of body weight or organ index between arsenic poisoning group and EXD (10 g) treated arsenic poisoning group, while CH50, lymphocyte accruing rate, phagocytosis rate, and mavrophocyte index were significantly higher in EXD (10 g) treated arsenic poisoning group than those in arsenic poisoning group (P.05 or P.01). In EXD (5 g) treated arsenic poisoning group, results of all the tested indexes were the same as those of arsenic poisoning group.
