By using the method for positive term resolution of equations of higher degree, all non-zero real roots of a real coefficient equation of higher degreewere obtained by determiningthe abscissas of intersection points of two monotonically increasing concave functions in the first quadrant of a planar rectangular coordinate system.

用高次方程正项分解方法，将求解实系数高次方程非零实数根的问题，转化成求解两单调上升凹函数在平面直角系第一象限内交点横坐标的等价问题；给出了基于共享存储多指令流多数据流并行计算模型求解任意实系数高次方程全部实数根的大范围收敛性异步并行迭代算法，并分析了算法计算的复杂程度。

The sex needs to say from the beard, does not have the long beard thefemale, has also is only some fantastic story strange events, theprobably long beard all is a male, may have the masculine not longbeard, has also is the weed is difficult to plough, ten eightinadequate climates, do not have the man taste, therefore some peopleare called on the play "positive wither", like this really is awkward,does not have the pubic hair like the man, but this although covers upthe matter, but in the heart a little energy is also insufficientflavor.

识性别要从胡子说起，没有长胡子的女性，有也只是一些奇闻怪事，大概长胡子的都是男性，可有的男性也不长胡子，有也是荒草难耕，十根八根的不成气候，没有男人味，因此有人就戏称为"阳萎"，这样确是尴尬的，就像男人没有阴毛，可这虽是遮掩之事，但心里也有点底气不足的味道。

The results showed that POD activity increased at first and then decreased in the skin and flesh of root. The peak occurred at 40 d and 60 d in the skin and flesh, respectively. POD activity in the skin was higher than that in the flesh at 30 d and then contrary results were observed. The higher POD activity was, the more POD isoenzyme was. The pattern of POD isoenzymes was different between skin and flesh at different vegetative growth stages. POD isoenzymes in the skin were composed of five monomers and four dimers while five dimers or two monomers, two dimers and one tetramer in the flesh. POD isoenzymes in the root were mainly acidic. POD localized mainly in the cell walls of periderm, cambium, xylem ray, xylem vessels and primary xylem.

结果显示，心里美萝卜营养生长期肉质根的皮和肉中POD活性均先升高后降低，分别在播种后第40 d和60 d出现峰值，30 d时皮中POD活性高于肉，之后则相反，酶活性最高时同工酶数目也最多，不同时期，皮和肉中同工酶种类不同；皮中POD同工酶由5个单体和4个二聚体组成，而肉中由5个二聚体或2个单体、2个二聚体和1个四聚体组成，均以酸性同工酶为主；组化定位显示POD主要分布在肉质根的周皮、形成层、木射线、木质部导管和肉的初生木质部等的细胞壁附近。

To properly explore the photoreceptor for the negative phototropism in rice (Oryza sativa L.) root, lights with different wavelengths were applied to investigate the effect of light quality on phototropic response. The negative phototropic bending could be induced prominently by blue/UV light, while not be induced by red and far-red light.

为了研究水稻根负向光性的光受体，观察了光质对稻根的负向光性效应，用紫外－可见分光光度计测定了水稻根冠浸提液的吸收光谱，并对根冠中的蛋白质进行了SDS-PAGE电泳分析。

The division with surplus, the comprehensive division and Eisenstein Test applications on polynomial that can not be divided are mainly discussed; the sufficient condition of that polynomial with coefficient being integer has no integer root, that cubic polynomial with coefficient being integer is irreducible in rational domain and that polynomial with coefficient being integer has not two completely same roots are summed up.

主要论述了带余除法、综合除法及不可约多项式艾森斯坦判别法的应用；总结出了整系数多项式的无整数根的充分性，三次整系数多项式在有理数域上不可约的充分性，整系数多项式无重根的充分性。

Fertilizing date presented obvious effects on root growth and distribution. Fertilization after watering was more primitive to the root in up-soil layers than before watering. Fertilization of Ca-Mg was positive to the increase of root in 5-15cm soil layer, but negative to that in the surface layer. Both fertilization date and Ca-Mg fertilizer affected root vigor obviously.

施肥时期对根系也具有明显的影响，与灌水前施肥相比，灌水后施肥有利于促进根系在上层土壤中的生长和分布；钙镁肥的施用能增加5~15cm土层根重，但对表层根的生长不利，施肥时期和钙镁肥施用与否对根系活力的影响也较大。

The extramatrical mycelium developing from the "nurse" seedlings infect roots on the younger seedlings.

在有些国家，移植具有大量外生菌根的松苗，以1至2公尺的距离栽植於新苗床。从&肥料&苗发育出来的外表生菌丝，会感染幼苗的根。

Last month, a UK insurance company Lucida announced the first longevity swap transaction based on the LifeMetrics index, agreeing to pay JPMorgan an income stream based on current longevity expectations in return for JPMorgan's promise to pay an income stream based on how long people actually live for.

上月，英国保险公司Lucida宣布了首笔基于LifeMetrics指数的寿命掉期交易，同意根据目前的寿命预期向JP摩根支付收入流，以换取JP摩根的承诺：根据人们的实际寿命支付收入流。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
