According to the comparative research on Guangnania, the diagnosis of the zosterophytes is expanded. It is suggested that their sporangia have the differentiation in the shape (reniform, rounded/globose to vertically elongate), dehiscence and valves (biconvex or concave/convex).

根据Guangnania的研究和对比，对工蕨类植物的特征进行了扩展，认为孢子囊存在形状（肾形—圆形／球形—纵向伸长）、开裂方式和两瓣的分异。2。

According to Biot-Savart law, the magnetic induction at the diameter position of the spin axis is calculated. Furthermore, using the internal and external radius of the Earth's outer core as well as the radius of the Earth and the magnetic induction at the Earth's magnetic pole, the volume charge density and surface charge density of the Earth's outer core have been obtained.

先根据毕奥-萨伐尔定律计算球形模型绕自转轴旋转时在自转轴直径上产生的磁感应强度；再利用已知的地球外核的内外半径及地球半径和磁极处的磁感应强度值，计算出地球外核的电荷体密度及面密度。

Cleavage produces a blastula a sheet of cells rounded into a sphere that in most species surrounds a cavity.

The spherical embryonic mass of blastomeres formed before the blastula and resulting from cleavage of the fertilized ovum.

桑椹胚形成于囊胚之前且处于胚胎期内的球形裂球群，由受精卵细胞的分裂而成

This mass loss creates a more or less spherical cloud around the star and eventually uncovers the star's blazing hot core.

质量损失在恒星周围造就了或多或少呈现球形的云团，并最终将恒星闪耀的炽热核心掀开。

The 1s electron cloud in hydrogen atom has the largest probability density distribution around a spherical shell with Bohr radius a 0. The author thinks the probability density distribution and electron cloud belong in fact,to statistic regularity, and imply a macro-time scale is used, therefore in hydrogen molecule the product of energy and time is far larger than Planck Constant.

氢原子中 1s电子的电子云呈球形，电子的最大几率密度分布出现在玻尔半径a0 的球壳内，认为几率密度分布及电子云属统计规律，意味着已经使用了宏观时标，这样就使氢分子体系中能量和时间的作用量远大于普郎克常数；根据电子云的交叠，用经典力学计算了基态氢分子的结构常数，获得键长、键能及力常数的表达式分别为Re=2a0 ，De=ze/4 2a0 ，k=ze/2 2a30 ，采用原子单位 a 。u 。

He designed the Bombe coffee set I and it is still in production 1945. The teapot from this set is still being used at

他在1945年设计的半球形咖啡组合I，时至今日仍继续生产，甚至连香港士丹利街的陆羽茶楼亦沿用至今

The results showed that the calcined bone ash obtained at 1200℃ had clear outline, spherical and mode-ratesize particles. These characteristics were benificial to improve the slurry fludity, broaden the sintering temperature range and increased the whiteness of bone china bulk. It is concluded that the moderate calcining temperature range of bone china bulk is 1200-1300℃.

实验结果表明，在1200℃下对骨灰进行煅烧，可获得轮廓清晰、周球形和颗粒尺寸适中的煅烧骨灰，有利于提高骨质瓷坯体浆料的流动性，扩大坯体烧结温度范围，并且能提高坯体的白度。

One is a spherical shape of 12 boron atoms.

一种是由12个硼原子组成的球形，另一种是由一对硼原子组成的哑铃形结构。

By far the largest part of an udoroot is its massive, bulbous root system, the bottommost tip of which can reach 30 feet below the surface.

一般一棵土当归根中最大的部分就是它厚重的球形根系，其根尖最深能达到地面以下30英尺。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
