根的

We studied the asymptotic properties of the integer part of the k-th root positive integer and gave an interesting asymptotic formula.

研究了一个关于正整数κ次根的整数部分序列的均值，并利用初等的方法得到了一个有趣的渐近公式： 3。

The results showed that NAA at low concentrations 0.1~0.2 mgL^(-1 was more beneficial for root induction, the rate of rooting was up to 100%. 1/4MS was more suitable to deal with the plantlet rooting and form small bulb. The optimal ratio of IBA and AC for rooting was 2.0 mgL^(-1) IBA+0.1%AC. The in vitro growth of plantlets were the strongest, and survival rate was 100% after incubating at 4℃ for 4 weeks when the diameter of bulblet was ≥9 mm.

结果显示；低浓度的NAA0.1~02mgL^(-1有利于根的诱导；生根率均达100%；大量元素1/4MS处理更适合试管苗的生根和小鳞茎形成；"IBA+AC"处理最佳组合是2.0mgL^(-1) IBA+0.1%AC；鳞茎直径≥9mm的试管苗去顶4℃低温冷藏4周；移栽后喷施1/2MS营养液；长势最好；成活率达到100%。

It is a celebration of our love of cars and the romance of travel and is a fitting model to announce during Morgan's Centenary year.

这是庆祝我们的爱汽车和浪漫的旅行，是一个合适的模式，宣布在摩根的百年。

Colicroot with yellow-bracted racemose flowers; smaller than Aletris farinosa; southeastrn United States.

Efficacy: DCE anti-acne constringing toner contains tea tree oil, dandelion, red sage root, honeysuckle, forsythia, salvia and other precious natural herbal extracts. It can efficiently and speedily break down grease, and penetrate into pores to prevent acnes exacerbating, constringe pores and control oiliness. Skins with occasional acnes will find acnes disappear in several days after using this product; while skins harassed with regular tough acnes will radically get rid of this trouble if a whole bottle of toner is used. And one or two bottles of this product are enough for skins with new acnes, recrudescent acnes, prosperous acnes or tough acne roots.

Therefore at each time we get the roots of this cubic equation, we can decide if we keep or reject each root according to the continuity of the curved surface, the method is as follows: If , the relative cubic plane curve is just a circle, this circle can be gotten by solving .

因此在每次求得该一元三次方程的解时，我们根据曲面的连续性来判断这些根的取舍，方法如下：在处，所得的平面曲线就是圆截线，该圆截线可以由相截得到，即。

Furthermore, supplements of callus induction medium under N6 basic medium,such as concentration of 2,4-D, proline and casein hydrolysate were used to study their effects on the induction frequency,embryogeny and quality of callus,the inhibition of embryo spontaneous shooting.

幼胚在附加4 mg/L 2，4-D且去掉水解酪蛋白和L-脯氨酸的N6改良培养基上，幼芽及根的数量少、出愈率高、愈伤组织质地好，并明显减少了幼胚自发性芽分化的趋势，有利于保持愈伤组织胚性、提高再生植株频率，为玉米自交系幼胚诱导的适宜培养基。

There Morgan clanked, blackened and sun-dried, for three years, pour encourager les autres.

三年时间，摩根的脚镣在那里随风发出清脆的叮当声，那里的日光烤黑蒸干了他的身体。

The way of working out the problem of taking two line segments as the root of an equation is to link up monodic quadratic equation directly with geometry and establish the connection between them.

以两线段长为一元二次方程的根的问题的解法，是把一元二次方程与几何问题直接挂钩，沟通了几何与二次方程之间的联系。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
