In this paper, the transformable conditions and the transformation matrices of two arbitrary B-spline bases are studied, and the theoretical results about the representation and properties of the elements of the transformation matrices are given.

本文研究任意两个B样条基可转换的条件及转换矩阵，给出了关于转换矩阵元素的表示及性质等理论结果，并推导出了两个递推公式，为实际计算转换矩阵的元素提供了易于实现的数学方法。

Transuranium elements with atomic numbers through 112, along with 114 and 116, have been produced in laboratories.

原子序数一直到112的元素，加上114、116和118元素都已经在实验室里产生出来。

A member of the actinide series of transition elements, it is the most important transuranium element because of its use in certain types of nuclear reactors and in nuclear weapons.

锕系过渡元素及其化合物，是最重要的超铀元素，用作核反应堆燃料和核子武器装料。

A member of the actinide series of transition elements, it is the most important transuranium element because of its use in certain types of nuclear reactors and in nuclear weapon s.

锕系过渡元素及其化合物，是最重要的超铀元素，用作核反应堆燃料和核子武器装料。

The naming of the transuranium elements has been fraught with controversy regarding which laboratory first made the discovery and should propose the name and whether elements should be named for living persons.

超铀元素的命名充满着争议，究竟是哪个实验室首先发现而应该命名，该不该以一个活着的人的名字为元素命名等。

Comparing size distribution of trace elements at haze weather and the normal weather discovered that,Ca、Ti、Fe、Cr showed significant enrichment in the small size particle at the haze weather:Cu,As didn't have different at such two kind of weather conditions;Zn、Mn、Pb appeared bimodal even trimodal distribution,whose suggested that there were a long distance transmission in originations of such three metals.

对比正常天气下的金属元素的粒径分布，发现：Ca、Ti、Fe、Cr 等元素在灰霾发生时细粒径上有明显的富集： Cu、As 在两种天气条件下区别不是很大：Zn、Mn、Pb 等元素在两种天气条件下均出现双峰甚至多峰分布。由此推断 Zn、Mn、Pb 的来源中可能存在长距离传输。

The level of soil fertility was high in GAP base, but nutrients distribution was unbalanceable: nitrogen and phosphorus in soil could basically satisfy the crop growth; but potassium was not enough.

对三七GAP基地的土壤质地、供肥特性和土壤肥力进行了调查和分析，结果表明，三七GAP基地土壤以壤质粘土为主，偏酸性，土壤肥力水平较高，但各养分因子分布不平衡，氮、磷元素基本满足三七生长的需求，而钾元素普遍不足，在栽培管理上，应根据三七的生长特点、不同生长期及具体的种植片区对养分的要求制定施肥方案，并注意多施钾肥。

Absolute tonal neutrality, outstanding dynamics and a so far unknown level of resolution are trademarks of our amplifiers, complemented by an explosively fast and uncoloured bass and high power triode performance.

绝对忠实的音乐还原，卓越的动力性能，久负盛名的高水准音场解像度，是我们不可或缺的元素，整机装备在极速反应、不添加任何色元素、功率储备充足的胆管上。

From early to late, the ratio of Rb/Sr, Rb/Ba and the content of uncompatible elements ascent and the ratio of K/Rb, Ba/K, LREE/HREE and δEu, the content of compatible elecments descent, Which is the result of differentiation of granite magma.

由早至晚，岩石中Rb/Sr、Rb/Ba比值及不相容元素含量升高，K/Rb、Ba/K、LREE/HREE、δEu及相容元素含量降低，反映了本区的花岗岩岩浆分异演化特征。

As the Titans made their way across the primordial landscape, they encountered a number of hostile elemental beings. These elementals, who worshipped a race of unfathomably evil beings known only as the Old Gods, vowed to drive the Titans back and keep their world inviolate from the invaders' metallic touch.

泰坦在制作这个世界风景的时候遇到一伙有敌意的元素生物，这些元素信奉一些邪恶生物，据说是这些邪恶生物是古老的神，他们发誓要把泰坦赶出这个世界，他们不希望泰坦的用金属手改造这个世界。

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。
