The results showed that two of the ball cactuses tested could growth well in solution culture , in which the growth rate was significantly higher than or equal to that in peatmoss culture. Among the four solution culture formulae , formula 4 had the highest biomass increment and uptake of N , P and Kfor Ferocactu horridus. The biomass of Echinopsis calochlora did not differ significantly among the four formulae , but significantly increased higher than medium culture. This study indicated that ball cactuses could grow well in nutrient solution culture.

结果表明：经100 d 种植，供试的仙人球在这4 种营养液配方静置水培中均能正常生长，而且生长速度显著大于基质栽培或与之相当；在4 种营养液配方中，巨鹫玉在完全硝态氮的配方处理中球体质量的增加比基质栽培的快1 倍以上， N、P、K的吸收量也显著高于其它含有铵态氮配方的；而金盛球在所有营养液配方中生长量均显著高于基质栽培，球体质量增长量超过基质栽培的1 倍以上， 4 种配方间无显著差异。

During valve operation, the friction between the ball and the PTEE seat ring will produce electrostatic charges and they

当操作阀门时，由于球体和聚四氟乙烯阀座之间的摩擦，会产生静电电荷积聚在球体上。

In the Eines pack,you will find the necessary tools for spherification:syrings for measuring out the drops that produce spherifical caviar,dosing spoons of different diameters for making ravioli,gnocchi or spherical balloons;and collecting spoons,used to rinse the preparation once it has been submerged in the calcic bath.

首先，形状和尺寸就有严格的规定，最合适的工具必须选择：注射器不被用来做球状的鱼子酱。还有大量的准备（迷你小球体，馄饨，马铃薯饼，气球等），做的汤匙将会被用到。汤匙被用来移动和清洗化盆里的球体准备物质。

In this article, the other half of ball reaction will be broken down and investigated.

前一篇文章我们提到球心动态与球体表现的关系，在这一章节，我们将深入剖析另一方面关於&球体反应&的部分。

An analytic equation for electromagnetic response of semi-space sphere is derived. The areal, pseudo-sectional and frequency responses of low and high resisting buried sphere trippers in the even semispace are calculated, the characteristics and rules are analyzed.

推导出基于半空间中球体的电磁响应的解析式，计算了均匀半空问中低阻和商阻埋藏球体的倾子的平面、拟断面和频率响应，分析了其特征和规律。

The proposed method is firstly applied to calculate the added mass of a sphere and spheroids moving in unbounded fluid. The numerical results are compared with the theoretical ones to check the validity of the proposed method.

为了验证本文开发的高阶面元法的有效性，首先对无界流场中的球体及一般椭球体的附加质量进行了数值计算，并将计算结果和理论结果进行了比较。

The fusion kinetics and steady length of rods formed by smaller versus larger spheroids (approximately 100 vs. 300 microm diameter) were indistinguishable, even though smaller spheroids had twice the surface area and greater numbers of contacts between units.

由较小的和较大的球体（约100和300微米直径）形成的融合动力学和稳定的柱状长度没什么区别，虽然较小的球体有两倍的表面积，单位间有更多的接触。

Normal human fibroblast spheroids were self-assembled and cultured for 1, 4, or 7 days, then combined in trough shaped recesses. Over a 24-h period the spheroids fused to become a rod shaped microtissue and the kinetics and extent of fusion could be quantified by assessing rod contraction.

正常的人成纤维细胞可自我聚集形成球体，并培养了1、4、7天，然后在槽状的凹处中进行结合。24小时时间段过后，球体融合成柱状的微组织，融合的动力学及程度可以通过评定这种小柱的收缩而进行定量分析。

In July, an international team of craftsmen unveiled an unusual pair of balls - believed to be the roundest objects in the world.

今年7月，一个由工程师和能工巧匠组成的国际团队制作了一对完美的硅球体，该硅球体被认为是世界上最圆的物体。

Using linear accelerator,the dose rate of the 6MV X-ray was 2Gy/min.The A549 spheroids was not more sensitive to low doses of single radiation.After exposure to 2-8Gy radiation,the spheroids recured quickly.Thetreatment of fractional radiation were more effective than single ones.With the increase of radiation doses,the 〓-M% block increased,numberof dead and apoptosis cells increased.

直线加速器产生的6MV高能X射线，2Gy／min的剂量率照射，A549多细胞球体对低剂量单次放疗不太敏感，2-8Gy范围内低剂量放疗后球体细胞很快增殖复发，分割放疗疗效优于单次放疗。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
