But it is very difficult to have good mechanics function and antifouling capability if we use organic polymer resin simply.

因此本文通过有机硅单体与丙烯酸酯类单体进行共聚制得具有低表面能特性的有机硅改性丙烯酸树脂。

The results show that: the fillers of SiO_2 based investment consist of SiO_2,Al_2O_3 and MgO,and the binder is NH_4H_2PO_4;for SiO_2 based investment,the bulk density and the compression strength decrease,the apparent porosity and the thermal expansion increase,when the specimens are heated to 900 ℃;the fil.

结果表明：氧化硅系包埋料的骨料是氧化硅、氧化铝、氧化镁，结合剂为磷酸二氢铵，其900℃煅烧后显气孔率增加，体积密度下降，耐压强度降低，热膨胀增大；氧化铝系包埋料的骨料是氧化铝和氧化镁，结合剂为磷酸二氢铵，其900℃烧后显气孔率增加，体积密度下降，热膨胀变化不大；氧化镁系包埋料的骨料是氧化镁和氧化铝，结合剂是铝酸钙水泥，其900℃烧后耐压强度明显降低，热膨胀明显增大。

To restore the ability of chromium can be dissolved in sulfuric acid, hydrochloric acid and High-FE acid and release hydrogen, but also of pure chromium with aqua regia does not work, when there is the presence of halogen ions in the acid can not be long-term stability, high temperature with alkali, hydrogen sulfide, sulfur steam, phosphorus, ammonia, such as carbon monoxide and water vapor reaction of the corresponding compounds, in the high temperature reaction of silicon into the silicide also chromium, chromium alloys with many metals generate a wide range of industrial applications, such as chromium-manganese stainless steel is used extensively for chemical plants.

铬的还原能力强，能溶于硫酸、盐酸和高FE氯酸而放出氢气，但纯铬连王水也不起作用，当有卤素离子存在时，在酸中不能长期稳定，高温时能与强碱、硫化氢、硫蒸汽、磷、氨、一氧化碳和水蒸汽等反应生成对应的化合物，在高温下还能与硅反应成硅化铬，铬能与许多金属生成合金广泛在工业上应用，如铬锰不锈钢大量用于化工设备。

Si-Mo Pole electrical-heating elements is a resistance generate-heating component made from Si-Mo or the baric material.

硅钼棒电热元件是一种以二硅化钼为基础制成的耐高温、抗氧化、低老化的电阻发热元件。

The bimodal pattern of nutrient variation is characterized by consumption in spring, increase in summer and autumn, and accumulation in winter.

河流输送量的变化，对氮的影响最显著，对磷的影响次之，但硅对河流的响应并不强烈，这因为胶州湾的硅主要来自底矿化。

LST reef characterized by aggradational bioherm or patch reef is generally associated with mixed clastic turbidite, siliceous limestone and mudstones reef.

低水位礁仅发育于台盆背景，以加积丘礁或点礁为特色，常与混屑浊积岩、硅灰岩、硅泥岩共生。
