The paper studied influence of tungsten on microstructure and properties of Cr24 high chromium cast iron.

研究了钨元素对Cr24高铬铸铁组织及性能的影响。

Further increasing the Cr thickness results in larger grain size and fewer hillocks in the Al pads.

附著性方面，当於铝和ITO锡薄膜间，沈积10 nm的铬薄膜，即可明显提升薄膜附著性，薄膜附著性由小於0.25 N/mm2提升至47.78 N/mm2。

Objective To explore the acute toxicity of arsenic,chromium,lead,cadmium,hydrargyrum to luminescent bacteria Vibrio qinghaiensis sp-Q67 at normal temperature(25℃).

目的探索常温(25℃)下水中砷、铬、铅、镉和汞对发光菌青海弧菌Q67的急性毒性效应。

Thus, Chinese current standards include 12 heavy metals and harmful substances in apple, such as lead, cadmium, hydrargyrum, abio-arsenic, chrome, arsenic, selenium, copper, fluorine, rare earth, nitrite, nitrate, and also the residue limit of 56 pesticides.

至此，我国现行标准中，共包含了苹果中铅、镉、汞、无机砷、铬、砷、硒、铜、氟、稀土、亚硝酸盐、硝酸盐等12种重金属和有害物质以及56种农药的残留限量。

Reaction mechanism for 11,1,2-tetrafluoroethane preparation is carried out through gas phase fluorination by hydrogen fluoride over chromium-magnesium fluorination catalysts with trichloroethylene as main materials and dynamics models are set up.

研究了以三氯乙烯为主要原料，在铬镁氟化催化剂存在下，用氟化氢气相氟化制备1，1，1，2-四氟乙烷的反应机理，建立了动力学模型。

The processes for preparing collagen and collagen hydrolyzate from chrome shavings have been summarized in the present paper.

本文对从铬鞣革屑中提取胶原及其降解产物的方法进行了综述。

Results toxic test and ld 50 test showed that nata de coco strain was free from toxin.quality control system has not been established and sanitary facilities were incomplete in most fac-tories.totally54samples of nata de coco were hygienically determined.the pollution level of elements of pb,as,nitrate and nitrite was low,but chromium was relatively higher.no aflatoxin b 1 and pathogenic bacteria were detected.the residual hydrogen peroxide were detected from15out of the18samples detected.

结果 菌种毒力试验和急性毒性试验（ld 50 ）显示为无毒物；多数企业未建立卫生管理制度，卫生设施不完善；采集54份椰果样品做卫生学检测，铅、砷等重金属元素、硝酸盐、亚硝酸盐污染水平较低，铬含量相对较高，未发现黄曲霉毒素b 1 和致病菌的污染；18份椰果样品中有15份残留过氧化氢。

By the method of sand culture, this paper studied the effects of different concentration chromium 0, 100, 200, 300, 400, 500, 600, 800 mgL^(-1 on the matured hypocotyl germination and seedling growth of Avicennia marina on 25, 45 and 150 days of treatment.

采用砂基栽培，研究重金属铬不同胁迫强度0、100、200、300、400、500、600、800mgL^(-1和胁迫时间（25、45和150d）条件下，对红树植物白骨壤成熟胚轴萌发及幼苗生长的影响。

You can now rename the shortcut to something more appropriate and use Chrome in Incognito Mode directly.

现在，您可以重命名该快捷方式的东西更合适和使用铬隐姓埋名在直接模式。

Artificial mechanical cardiac valve was produced by Lanzhou Flight Control Instrument Factory. Prosthetic valve frame was acid-resisting chrome-nickel alloy of high intensity, valve ring was polyester filament fabric, valve was consisted of graphite matrix in interior and deposited hydrolytic carbon on surface.

人工机械心脏瓣膜由兰州飞控医疗仪器厂生产，为C-LⅠ型短柱人工机械心脏瓣膜，瓣架为高强度耐酸铬镍合金，瓣片的内部为石墨基体，表面为沉积热解碳，瓣环为涤纶长丝织物。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
