由于n个元素的有限集有且只有个子集由于个元素的有限集有且只有2n个子集，而且很显然有限布个元素的有限集有且只有个子集，尔代数一定是有限集合代数，所以对某个整数n而言而言，尔代数一定是有限集合代数，所以对某个整数而言，每个有限布尔代数也有且只有2n个元素。例如，上文定义的集合T的限布尔代数也有且只有个元素。

These kinds of analytical elements can describe the crack tip fields for the Dugdale model and can also be combined with the ordinate finite elements to form the semi-analytical finite element method.

该类超级单元能够准确地描述基于Dugdale模型的裂纹尖端场，可与普通有限单元相结合，构成半解析有限元法。

To improve temperature uniformity,trolley electric furnace heated by three districts, in accordance with temperature arrangement method arrange heating elements, compensation for loss of furnace heat mouth, I District II District III district heating elements layout of the different, but the car high-precision temperature furnace heating and insulation in the process of maintaining three districts temperature consistent.

可为用户定做各种规格尺寸高精度高温台车电炉。为提高炉温均匀性，台车电炉采用三区加热，并按均温布丝法布置加热元件，为补偿炉口热损失，I区II区III区加热元件布置范围各不相同，但使高精度高温台车电炉在升温及保温过程中保持三区均温一致。

Carbon lies midway in the periodic chart between the strongly electropositive elements of group I-A and the strongly electronegative elements of group VII-B.

碳在元素周期表上位于I-A族强正电性元素和VII-B族强负电性元素之间。

The flora has the characteristics of both old and new elements, complicated differentiation, young elements mainly,obvious substitution and endemism phenomena. It is the center of alpine flowers and current diversified pine and cypress plants.

为主；替代现象明显、特有现象显著；与北温带联系紧密，高山花卉和现代松柏类植物多样化中心；是中国低纬度高海拔地区植物资源保存比较完整而原始的地区。

You very eugenic awareness should really fill in advance, because any trace elements are not able to fill the entry into force of a body will take some time to accumulate, especially the Chinese people from the dietary intake of trace elements is low.

你很有优生意识，确实应该提前补，因为任何微量元素都不是一补就能生效的，人体需要一段时间来进行积累，特别是中国人从膳食中摄取微量元素的比例很低。

The distributive characteristics of Sr, Sc, K and REE such as Ce, Y are consist with Ca to some degree. Which means those elements host in Ca〓 sites of francolite. Certainly, other sites of these elements are still exist. It is sug gested that the change of mieroenvironment is the cause of the variation of Mn.

Sr、Sc、K及稀土元素Ce、Y在结核内的分布形式在一定程度上与Ca的位置，当然，它们还有其它赋存形式，Mn的变化可说明了磷结核形成作用过程中微环境发生了一定的变化。

Developed from GNZ series of mobile suits, the chassis is reused from GN-008GNHW/B Seravee Gundam GNHW/B and shows some similar design elements of the GNZ-series of mobile suits, like the GNZ-001 GRM Gundam and GNZ-003 Gadessa, as well as some elements from the GN-002 Gundam Dynames.

拉斐尔高达从GNZ系列MS发展而来，同时重新运用了GN-008GNHW/B Seravee Gundam GNHW/B的骨架，在设计元素上与GNZ系列有相似之处，同时也采用了GN-002 Gundam Dynames的一些元素。

A Lithium-Bromide absorption refrigerating machine is designed using inclined fin tubes as heat transfer elements for absorber and using other corresponding heat transfer enhancement elements for the other heat exchangers. Comparing with the machine of using bare tubes, this unit can save bronze by 19%, steel by 28%, space by 36%. And a lot of operating expenditure can be reduced at the same time.

用斜槽管作为吸收器中的传热管，并在其它传热部件中采用相应的强化传热元件，设计了一台溴化锂吸收式制冷机，与全部采用光管的机组相比，节省了19%的铜材、28%的钢材，整体体积减小了36%，同时还节省了其它费用，显示出较好的经济效益。

Under light microscope, on H-E stain section, four types cells can be distinguish: cells with weak basophilic fibrillar elements; cells with acidophilic granular substance; cells with strong basophilic fibrillar elements and ciliated cells. In the basal lamina region under gland epithelium, there are a few connective tissue; Surface view of the hypobranchial gland could be see by scanning electron microscope, there are cilia and different kinds of secretions distributed. Ultrastructure of the hypobranchial gland could be understand by transmission electron microscope, supporting cells, sensory cells and seven types gland cell were observed to form the glandular epithelium; cells with much rough endoplasmic reticulum,smooth muscle fiber and nerve endings were found beneath glandular epithelium, among basal lamina region.
