Using geomodel 1 . 0 , users can ( 1 ) manage the database of geochemical data , ( 2 ) get atomic weights and molecular weights of minerals , ( 3 ) model geochemical reaction of the species in the database and , ( 4 ) obtain information about geochemistry and modeling theories . compared with analogous software , geomodel 1 . 0 has followed characteristics : ( 1 ) employing database system instead of text files to save data , ( 2 ) introducing the conception of base species and using it in modeling , and ( 3 ) having a friendly and visual interface which is all in chinese 和同類型的軟件相比較, geomodel1 . 0具有以下特點: ( 1 )用數據庫而非文本的方式對地球化學反應參數進行管理; ( 2 )引入基物種的概念進行地球化學反應模擬; ( 3 )程序充分的利用計算機的智能特性,控制模擬流程,人為干預很少; ( 4 )允許用戶對數據庫中的數據進行擴充和編輯; ( 5 )具有簡單、明了的可視化中文界面。

In this article the method of microscale experiment used in the determination of copper atomic weight is introduced and some individual experience on making inorganic chemistry experiment microscale is mentioned 摘要本文詳細介紹了銅原子量測定實驗的微型實驗方法,另外還就無機實驗中實行微型化談出了個人的幾點體會。

The most common isotope of oxygen , for example , has an atomic weight of 16 , but there are also rarer isotopes with weights of 17 and 18 , caused by additional neutrons in their nuclei 例如很常見的同位素氧,原子重量是16 ,但是還有更為稀少的重量為17和18的同位素,這是因為它們的原子核中有額外的中子。

Isotopes are different varieties of the same type of atom , all completely identical in their chemical behavior , but differing slightly in their atomic weight 同位素是同一原子的不同品種,具有完全吸納共同的化學特性,只是它們的原子核重量有點不同。

Mobile dictionary that contains information such as atomic weight , date of discovery , country of discovery etc . about all elements 移動字典:關于原子量,元素發現時間,在哪個國家發現等等,一切的內容都和元素有關。

Isotopes are different varieties of the same element , which have identical chemical properties but differ in atomic weight 同位素是同一元素的不同種類,它們有著相同的化學特性但是原子重量不同。

An isotope of hydrogen with one proton and one neutron in the nucleus having an atomic weight of2 . 014 氘氫的一種同位素,在其原子核內有一個質子和一個中子,其原子重量為2 。 014

In order of ascending atomic weight 以原子重量由小到大是:

The molecular weight of a molecule is the sum of the atomic weights of the constituent atoms . 一種分子的分子量就是構成它的原子成分之原子量總和。
