In this paper,the effect of the compound stress of Cu,Cd,Pb,Zn and As on the growth and the accumulation and the distribution of heavy metals in Juncus Effuses is researched by using soil cultures method.

盆栽试验结果表明：Cd、Pb、Cu、Zn、As 5种重金属复合胁迫对灯心草地上部生长有一定程度的抑制作用，在土壤环境质量二级标准上限值处灯心草地上部生物量减产9。

Eco-toxicology effects of compound stress of Cu, Cd, Pb, Zn and As on growth, chlorophyll content and protective enzyme of Juncus Effuses were studied using pot culture. Concentrations of the heavy metals in the soil were designed according to the State Soil Environmental Quality Standard. Considering practical application, soils contaminated with tailings and wastewater from Lead/Zinc mining were also used in the experiment.

Methods One hundered and fifty patients with hypertension were randomly divided into three groups,with each of 50 cases.The levels of blood pressure,hypokalemia,blood sugar,uric acid,lipide were examined before and after treatment.

将符合诊断标准的150例老年高血压患者电脑随机分为3组，每组50例，进行用药前后自身对照试验，8周后检测各组血压、血钾、血糖、尿酸、血脂值。

Abstract］ objective to observe the effects of indapamide and losartan alone and combined treatment on the elder patients with hypertension,hypokalemia,hyperglycemia,uric acid,lipid,ect.methods one hundered and fifty patients with hypertension were randomly divided into three groups,with each of 50 cases.the levels of blood pressure,hypokalemia,blood sugar,uric acid,lipide were examined before and after treatment.results after 8 weeks the systolic and diastolic blood pressure were significantly lower.antihypertensive treatment group is the best,the levels of hypokalemia is lower after treatment in the indapamide group,the levels of uric acid is also lower in the losartan group and antihypertensive group.conclusion losartan and indapamide combined treatment not only coordinate to decrease blood pressure but also reduce uric acid,reduce the effect of hypokalemia caused by indapamide.

目的 观察氯沙坦与吲哒帕胺单独应用或联合用药对原发性高血压患者血压、血钾、血糖、尿酸、血脂的影响。方法将符合诊断标准的150例老年高血压患者电脑随机分为3组，每组50例，进行用药前后自身对照试验，8周后检测各组血压、血钾、血糖、尿酸、血脂值。结果 3组治疗后收缩压和舒张压均较前明显降低，联合治疗组降压幅度最大，氯沙坦组和联合治疗组治疗后尿酸值较治疗前降低，吲哒帕胺组治疗后血钾值较治疗前降低。结论氯沙坦与吲哒帕胺联合应用不仅具有协同降压作用，而且能降低尿酸，减轻吲哒帕胺引起的低钾血症。

Objective To establish the quality standard for Lithospermum anti-inflammatory tablets.

目的 为了建立紫草消炎片的质量控制标准，本试验进行了定性鉴别研究。

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。

All weighing tests should be made in the standard atmosphere for testing textile.after the specimens have been conditioned in the same atmosphere.it may be impractical to condition the specimens in option A or nonconditioned testing may be agreed upon by the purchaser and supplier.when the full rolls or bolts of fabric can not be properly conditioned in a resonable time with available facilities,perform the tests without conditioning and report the actual conditions prevailing at the time of the test.such results may not correspond with the results obtained after testing adequately conditioned specimens in the standard atmosphere for testing textiles.

D1776实际操作的定向试块。纺织品的所有的权衡测试都应该在标准大气压下进行。当试块被置入同等气压的条件之后，或许将试块限制于A选项是不切实际的，而且有可能条件测试并不一定会被供应商和客户认同，当充满凹凸不平和毛刺的织物不能被适当的限制与合理的时间和现有的设施的时候，在没有限制的情况先执行试验并准确的报告在测试时的有力条件。这样得到的对纺织品测试的结果或许会与在真空中得到充分限制测试的结果不相一致。
