掩蔽

If there is adrop in X-ray receipt when GOES-O is in eclipse behind the Earth,why would there be aspike when the satellite is at dusk?

倘若GOES-O卫星在地球背面被掩蔽时，收到的专业心理测试题目X射线的量消沉了，那卫星在傍晚的时刻X射线的量又若何会上升呢？

Using EDTA as titratant,murexide as indicator,sodium tartrate ammonium fluoride and sodium thiosulfate as masking agent, nickle concentration was determined in ammonic medium.

以EDTA为滴定剂，紫脲酸铵为指示剂，NH4F、酒石酸钾钠、Na2S2O3为掩蔽剂，在氨性介质中测定镍的浓度；在pH值为8.0的氨-氯化铵缓冲液中，采用滴定比色法测得钴的浓度。

Microcapsulation technology is adoptted to shelter the offensive smell and the color of the deer placenta polypeptide in the test, the result is fine. Also the antioxygenic property of the deer placenta polypeptide microcapsule maintains well.

试验中采用微胶囊技术对鹿胎盘多肽的腥味和颜色进行掩蔽，效果良好，并且微胶囊化的鹿胎盘多肽抗氧化性保持较好。

RESULTS:In the Chenxiang Lubailu table,the identification of bismuthic salt positive result with dilute nitric acid instead of hydrochloric acid and the white precepitation formed in identification of magnesian was bismuth hydroxide sediments,it was easy and accurate to identify bismuthic salt by adding ascorbic acid.

结果：该片中的铋盐碘化钾鉴别反应，用稀硝酸代替盐酸做溶剂，呈正反应；镁盐氯化铵-磷酸氢二钠鉴别反应，加氨试液后，析出的白色沉淀不是Mg2，而是Bi3，该沉淀在氯化铵试液中不溶，干扰镁盐鉴别；铋盐含量测定项，用加抗坏血酸掩蔽剂的方法，排除Fe3+的干扰，使终点颜色稳定，易于准确判断。

A mixed indicator composed of bromocresol green, methyl red and phenalphthalein was used as indicator in titration of boron after the inteterience of cobalt was masked by EDTA.

采用甘露醇强化硼酸滴定硼时，以EDTA为掩蔽剂，可消除二价钴对硼分析的干扰；改用溴甲酚绿-甲基红-酚酞三元混合指示剂作为测定硼的指示剂，使滴定终点灵敏，准确。

Other methyl nucleophiles includingMeMgBr, MeCeCl2, MeTiCl3, Me3Al, Me3ZnMgCl, MeMnClwere tried, but in all these cases no detectable amount of exo-C8-methylated product was obtained. Although protecting C3-carbonyl as 1,3-dioxolanes could be achieved, the serious enolization of C8-carbonyl was still problematic. Converting C9-furan ring to α,β-butenolide did depress the enolization, but desired C8-methylation was completely replaced by migration of the double bond of the butenolide.

在本论文的早期阶段，主要着眼于解决二环[3.2.1]-C8-羰基加成甲基所遇到的C9-呋喃环差向异构化和C3与C8两个羰基之间化学选择性的问题：通过引入不同金属降低甲基试剂的碱性并没有取得甲基化的成功；通过不同的方法将C3-羰基掩蔽，但是C8-羰基的烯醇化依然无法抑制；虽然通过将呋喃环转化为α，β-不饱和-γ-丁内酯可以抑制烯醇化，但内酯环上的双键迁移又成了新的竞争反应。

Right now I am using Homeopathic Tinnitus Remedies to help me with my tinnitus, as well as tinnitus masking therapy.

现在，我使用顺势耳鸣的补救措施，帮助我与我的耳鸣，以及耳鸣掩蔽治疗。

Therefore can pass to use the cupric sulfate sulfuric acid potassium for the catalyst take sulfuric acid as to carry the body to digest it, make the amino acids chelate match the conversion for dissolve sex easily of ammonium sulfate and white vitriol, then absorb a fixed amount to try the kind to join 40% sodium hydroside combine under the steam heat function make ammonia the spirit swims to leave out, through cool off to respond the born boric acid with boric acid, be got the total nitrogen content by the standard aqua titration of hydrochloric acid immediately after;But the white vitriol can immediately join the hydrochloric acid hydroxylate , fluoride to turn the in order to cover up, carry on the titration but get the content of its zinc with the EDTA mark liquid..

因此可以通过用硫酸铜硫酸钾为催化剂以硫酸为载体将其消化，使氨基酸螯合锌转化为易溶性的硫酸铵和硫酸锌，然后吸取一定量的试样加入40 %的氢氧化钠并在水蒸气高温作用下使氨气游离出来，经冷却与硼酸反应生成硼酸铵，接着由盐酸标准溶液滴定得到总氮含量；而硫酸锌即可加入盐酸羟铵、氟化氢铵为掩蔽剂，用EDTA标液进行滴定而得到其锌的含量。

The thesis at last emphasized on the practical problems of Chinese movie's narration in postmodern times. The incurrent movies created by Chinese sixth-generation directors in the 1990s have many postmodern artistic peculiarities.

从电影叙事的意识形态来看，在后现代文化语境中，意识形态在影片本文的缝合与反缝合、掩蔽与去蔽的不断斗争中，不断地呈现出一些新的变化，这些变化逐渐形成了一种新型的意识形态腹语术。

With the classic iodometric method,this paper can work out the total effective chlorine, the sum of the chlorine and chlorine dioxide in the system.

按通常的碘量法可测定体系的总有效氯(ClO2 +Cl2 )；向体系中加入一定量的掩蔽剂二甲亚砜后可有效地掩敝体系中的Cl2 ，进而可测定体系中的ClO2 。
