The nickelous chloride both may use in to galvanize, and is prepares the galvanization chemical thionamic acid nickel the important raw material, lead is affects the electronickelling quality a important attribute, in the present industry 331 ion exchange resin deleading effect still could not arrive in the electronickelling the lead content standard, used pocket weak basicity resin XSC312 after the screening experiment determination to take from the nickelous chloride solution intermediate ion exchange except the micro lead resin, inspected the material fluid pH value, the contact duration in the ionic exchange column to the ionic exchange adsorption lead influence, has determined the resin adsorption capacity and inspected the resin analysis performance.
氯化镍既可用于电镀,又是制备电镀化学品氨基磺酸镍的重要原料,其中的铅是影响电镀镍质量的一个重要因素,现行工业中的331离子交换树脂除铅效果尚不能到电镀镍中铅含量标准,经过筛选试验确定采用大孔弱碱性树脂XSC312作为从氯化镍溶液中离子交换除微量铅树脂,在离子交换柱中考察了料液pH值、接触时间对离子交换吸附铅的影响,测出了树脂的吸附容量并考察了树脂的解析性能。

Three important conclusions are as follows:(1) the H2O content in garnet and omphacite can be up to 2000ppm and 3000ppm by weight respectively, indicating that they are significant carrier recycing surficial water into deep earth;(2) the heterogeneous distribution at the small scale of the H2O content and hydrogen isotopic ratios suggest that the whole subduction- exhumation process should be very fast;(3) the regular decrease of H2O content from rim to core within some garnet and omphacite grains indicates that hydrogen diffused out from mineral lattice during exhumation in response to sharp pressure decrease, and such hydrogen is expected to be involved in the early-stage retrograde metamorphism.
取得的主要科学认识包括:(1)石榴石和绿辉石的结构水含量可以分别高至2000ppm和3000ppm,这表明它们是板块俯冲过程中将地表水携带进地球深部的重要载体;(2)水含量和氢同位素组成表现出小尺度的不均一分布,说明板块的俯冲和折返过程是十分快速的;(3)在板块折返的早期,由于压力的降低,矿物中的H 会发生不同程度和尺度的扩散,这是早期退变质流体的重要来源。

In the generalization of contact lens develops day by day, on the issue associated with corneal infection due to incorrect habit of contact lens is put much emphasis. Pseudomonas aeruginosa is one of the most important infectious pathogens, it will adhere on the cornea and destroy the corneal tissue opportunistically with its quite violent virulence. The infected corneas will be attacked to necrosis by one to two days with very fast destructive speed. It is very important to diagnosis the infectious pathogen in time.
在隐形眼镜愈来愈普及的趋势下,因隐形眼镜配戴习惯不正确造成角膜感染的议题也逐渐受到重视,而绿脓杆菌正是其中最重要的一种感染病菌,其会附著在角膜上,然后伺机地破坏角膜组织,绿脓杆菌毒性相当猛烈,故其破坏的效率相当地快,角膜大概一至二天就会被摧残溃烂,因此即时诊断出角膜感染的病原体是相当重要的。

With the rich sediments supplied by the Pearl River, under the paleogeography sedimentary background of Baiyun Sag continuously subsiding, with sedimentary sequences related to relative transgressive sea level change ,contrary to regressive eustasy, the Pearl River Deepwater Fan System has specific evolution characteristics, which left the sedimentary record controlled by peripherical significant geological events. The sharp change of deposition rate and lithologic geochemical characteristics about 23.8Ma sequence boundary demonstratesd that sediment source had changed, perhaps related to the uplift of Tibet plateau and spreading of the South China Sea, which led the paleoPearl River drainage to expand to western China plateau , maybe much broader than present.
