TAS diagram for these three kinds of volcanogenic detritus, combined with variation diagram for Al2O, FeO(superscript *), MgO, CaO, Na2O, K2O vs SiO2, shows that there may exist bimodal volcanic activity in the north margin of the South China Sea, brown volcanic glass and colorless volcanic glass represent basic end member and acidic end member respectively, and crystallization differentiation is the main process for magma evolution.

在硅碱图及Al2O3、FeO、MgO、CaO、Na2O、K2O对SiO2，的变化趋势图中可以判断，本区可能存在双峰式火山活动，褐色火山玻璃代表中一基性端元，而无色火山玻璃代表酸性端元。无色火山玻璃与褐色火山玻璃具有共同的岩浆源区，结晶分异可能是源区岩浆演化的主要方式。

Observation is the first step in identifying the "skin" refers to the kogult into a transparent glass goblet to watch brightly colored.

鉴别的第一步是观察"皮肤"，指将kogult倒入透明的无色玻璃高脚杯以观察色泽。

Process:① the platinum wire dipped in concentrated hydrochloric acid to colorless colorless flame on the ignition;②sample in the colorless flame ignition, to observe the flame color (if test potassium cobalt glass through observation, because in most cases need to be used when the system of potassium sodium, potassium solution, therefore often contain sodium, and sodium yellow flame color reaction, a small amount of yellow and purple, respectively, can not come out).

3操作过程：①将铂丝蘸浓盐酸在无色火焰上灼烧至无色；②蘸取试样在无色火焰上灼烧，观察火焰颜色(若检验钾要透过钴玻璃观察，因为大多数情况下制钾时需要用到钠，因此钾离子溶液中常含有钠离子，而钠的焰色反应为黄色，黄色与少量的紫色无法分别出来)。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
