The basic steps of this method are as follows.The firststep is to derive a necessary condition such that the families of quasipolynomials withone parameter,corresponding to the edges of the polytope,have pure imaginary rootsby using the Dixon's resultant for polynomials.Then to check that the casescorresponding to the parameters obtained in the first step are in fact impossible byusing the generalized Sturm criterion and some stability criteria.

其基本思路是先利用多项式方程组的Dixon结式理论导出使各棱边对应的单参数特征拟多项式有纯虚根时，参数值应满足的一个等式条件，即所谓的Dixon结式等于零，然后由广义Sturm判别法验证对所有参数值，Dixon结式不等于零，或使结式等于零的解不产生特征拟多项式的纯虚根。

Regarding (6) type, when tradition Time variable t is two spatial vectors (+ psi 1i) and (- psi 2j) Crossed products v also is not 0, it (x1, x2, x3) differs 90 compared to on speed with the three-dimensional space in the space by the pure imaginary number attribute, I=e^I pi, therefore it Number space has in the physical property with the dot product constitution the difference, because Crossed products psi 1i (X psi 2j extremely small visible it is equal to zero under the conventional speed, but is very big in the object movement speed time, Crossed products psi 1i (X psi 2j in the physical quantity and for the quantum mechanics in may not to the easy quantity, its space and the conventional space is different, the performance is intrinsic or the interior space If the definition vector (+ psi 1i) and (- psi 2j) the dot product constitutes the three-dimensional space (x1, x2, x3) is exterior space, but the three-dimensional space which (+ psi 1i) and (- psi 2j) Crossed products constitutes by the vector is the internal space, contrasts its component

对于⑥式，传统时间量t为两个空间矢量(+ψ1i)与(-ψ2j)的叉积比上速度v且不为0，其与三维空间(x1，x2，x3)在空间上相差90度以纯虚数表征，I=e^Iπ，故其与点积构成的实空间有物理性质上的不同，因为在常规速率下叉积ψ1i(Xψ2j非常小可视其等于零，而在物体运动速率很大时，叉积ψ1i(Xψ2j之中物理量与则为量子力学中的不可对易量，其空间与常规空间不同，表现为一个内在或内部性空间。若定义矢量(+ψ1i)与(-ψ2j)点积所构成的三维空间(x1，x2，x3)为外部空间，而由矢量(+ψ1i)与(-ψ2j)叉积而构成的三维空间为内部空间，对比其分量

When however, once geometry, the network poison of pornography is in flood for originally the pure network sky hoodwinks one shadow, in particular in the last few years, is the young people which how many has has little experience of the world, not only does not have reasonably effectively to use more beneficial information which the network brings, instead lost own in in the network poison of pornography world, caused that originally is the youth encourages imaginary turns into one pale face and the empty look.

然而，曾几何时，网络黄毒的泛滥给原本纯净的网络天空蒙上一层阴影，尤其是近几年来，更是有多少涉世未深的青少年，不仅没有合理有效地利用网络所带来的更多有益信息，反而在网络黄毒的世界里迷失了自己，使得那本是青春的激扬幻化成了一张张苍白的面孔和空洞的眼神。

The changes of complex permittivity of pure-water,natrium oxalate,potassium permanganate and sodium chloride aqueous solution with different power were measured.It is shown that the changes of real part of the complex permittivity are all small and the imaginary part of the complex permittivity of electrolyte solution are obvious.

通过实验分别测量了纯水、草酸钠、高锰酸钾和氯化钠水溶液的复介电常数随微波测量功率改变的情况，发现4种待测物质的复介电常数实部都随微波功率改变较小，而草酸钠、高锰酸钾和氯化钠水溶液的复介电常数虚部随微波功率改变明显。

The genetic inactivation of eggs is the first key stage of androgenesis in fish. In order to observe the effect of UV irradiation for the inactivation of female nucleus of zebrafish the eggs were irradiated by UV with solution-free, pure water, Ringer's solution and Cortland solution. The results showed that abnormal fry were obtained in all groups and haploids were validated. But irradiation with solution was confirmed it could not inactive fully female nucleus and the fertilization rate of the eggs irradiated with pure water was very low.
