The main raw material for producing magnesium carbonate and magnesium are magnesite, dolomite and bitten, which have abundant reserves in our country, especially the reserves of magnesite and dolomite, that not only holds the domain position but also has superior quality in the world, which establish the massy material developing foundation of magnesium industry.
但我们也应该看到虽然我国具有发展镁盐产品的优越条件,但因目前绝大部分现有生产厂家均属乡镇企业,资金有限,生产规模小,设备陈旧,技术力量薄弱,提高产量及质量的能力受到限制,且生产的品种单一,使我国镁盐的生产仍处于粗制初级、原料性产品的阶段,远不能满足国民经济发展的需要,高档、功能化产品仍需从国外进口,出口产品的价格只有进口产品价格的几分之一。

结果表明:显生宙以来海水组分发生变化,经海相非骨骼灰岩和钾盐蒸发岩矿物学研究,发现这两种沉积岩长期以来连续变化,在"文石海"是MgSO4型蒸发盐,在"方解石海"是KCl型蒸发盐,从白垩纪晚期、第三纪早期的底部石盐溴含量及矿物学特征表明,此时处于"方解石海",古海水组分的特点是造成缺硫酸盐型钾盐矿床形成的物化基础;通过NaCl-KCl-MgCl2-H2O和NaCl-KCl-MgCl2-CaCl2-H2O两个体系相图的分析认为,当时所形成的成钾原始体系母液是高镁、低钾氯化物型的卤水,在母液蒸发过程中,由于原始海侵母液与残余高镁母液的掺杂作用,致使结晶路线直接从氯化钠区到E点母液或光卤石与氯化钠共饱线上,而没有通过氯化钠和氯化钾的共饱线,因而在矿体中氯化钾相很少或几乎不存在,由于外界CaCl2型水体的掺杂,使成钾母液进入光卤石相区,随着蒸发的进行,最终形成溢晶石矿物。

This paper analyzes the principle of the LP-LFC process,presents the physical and mathematical models of mould filling of the new process. The patterns including window-plate, ladders cluster, electromotor frame and exhausting manifolds are poured using LP-LFC process with AZ91D alloy, and the mould filling course is tracked with electrode touch point method. Based on above tests and experiments,the casting defects including short runs, cold laps, trapped gas,metal penetration, and so on, were investigated. The appearance characteristics,birth causes and influence factors of above defects are discussed in the article,diagrammatize modes of the defects forming is also given, and the measures of reducing or avoiding defects are put forward.

The amount of Ca8-P in soil with CRMP treatments was lower than that of CMP treatments. The changes of the amount of Al-P, O-P, Fe-P and Ca10-P in soil were neglectable during the course of experiment.3. The shoot and root weight of sorghum increased through application of phosphorus, in addition, The increase of sorghum shoot and root weight was greater than that of common monoammonium phosphate due to the slow release of nutrients from CRMP. The accumulative uptake of phosphorus in shoot and root with CRMP treatment was greater than that with CMP treatment in low (75 mg P2O5/kg soil ) and high(150mg P2O5/kg soil)rates, especially on middle stage, and in high phosphorus rate, this advantage was more obvious than that in low phosphorus rate.
磷肥的施入,促进了高粱地上部和根部的生长,而控释肥由于缓慢释放养分,与作物吸收相一致,更能促进高粱的地上部和根部干物质积累;对于高粱地上部及根部的磷素累积,在两种施磷水平下控释处理地上部及根部磷素累积量均大于非控释处理,尤其是在中期,而且高磷水平下优势更加明显,低磷控释处理的磷素累积量能达到高磷非控释的累积量,即减少一半的用量即能达到同样的效果;在氮、钾、钙、镁相同的水平下,控释处理比非控释处理更能促进地上部及根部氮、钾、钙、镁累积量,这种优势在中期表现最明显。4。

The result indicated that MgO and α- methacrylic acid can together thicken epoxy, and the speed of thickening epoxy become quickly with the increasing content of MgO; when the ratio of MgO and α- methacrylic acid is 3:1, thickening epoxy have a better effect; the thickening mechanism: the terminal corboxyl group of α- methacrylic acid react with MgO, and it accompany with large numbers of heat, the heat can accelerate the reaction between the terminal corboxyl group with the secondary hydroxyl groups of epoxy, intermolecular hydrogen bonding which the water of above-mentioned formation result in and complex compound which format the metal atoms and carbonyl group complexing collective increase the viscosity of epoxy resin.
结果表明:MgO和α-甲基丙烯酸配合可增稠环氧树脂,随着MgO加入量的增加,环氧树脂增稠的速度加快;MgO与α-甲基丙烯酸为3:1时,增稠环氧树脂的效果较好;推测环氧树脂的增稠机理是α-甲基丙烯酸中的端羧基与氧化镁反应,放出热量促使其端羧基与环氧树脂中的仲羟基反应,上述反应生成水产生的氢键和羰基与氧化镁中的金属原子形成络合物共同导致环氧树脂的粘度增加。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
