Nucleophilic opening of the terminalepoxide 57 by a lithium acetylide from 27 in the presence of BF3·EtO furnishedcompound 58, which had the skeleton of target molecule, subsequent conversionsinvolved the introduction of γlactone gave Annonacin.

然后以三氟化硼参与的炔负离子开环氧反应建立分子骨架，得到化合物58。随后经氢化，引入α，β不饱和丁内酯环、去保护等几步反应，就得到Annonacin。

After the analysis in Hulunber 301 section, the corrosion occurs mainly in inner corrosion and the outer corrosion is indistinctness. In affusion and heating system, the corrosion gives priority to oxygen corrosion, which the supplement of animalcule corrosion and carbon dioxide corrosion. In life drinking water system, the corrosion in stainless steel jar and pipeline wall usually generate welding line corrosion.

分析发现：贝301区块发生的腐蚀以内腐蚀为主，外腐蚀不明显；注水系统和采暖系统以氧腐蚀为主，微生物腐蚀为辅；还发生了以氢去极化为主的二氧化碳腐蚀；生活饮用水系统不锈钢罐及管线内壁发生的腐蚀主要是焊缝腐蚀。

Amino desacetoxycephalosporanic acid (7 - ADCA) is an ampholyte.

7-氨基去乙酰氧基头孢霉烷酸是两性化合物，从等电点两侧改变溶液的 p H值都可以产生过饱和度并结晶得到晶体产品，本文对 7-ADCA两种方法结晶的初级成核过程进行了研究。

Consider to discover, OSAHS patient appears because of relapsing in nightly Morpheus disease of blood of low oxygen, tall carbonic acid, consensual as disorder as parasympathetic nerve function, already made coronary heart disease (the cardiovascular disease such as CHD) sparks importantly element, can cause all sorts of rhythm of the heart wrong, aggravating cardiac muscle is short of blood, produce sudden death of heart source sex even. 1 O SAH S and hypertensive disease consider to discover, OSAHS patient's nightly small arousal can bring about sympathetic stimulant increase, adrenalin can nerve medium if adrenalin, go adrenalin secretes armour grow in quantity, heighten of material of phenolic amine of catechu of nightly make water.

探究发现，OSAHS患者夜间睡眠中因反复出现低氧、高碳酸血症、交感和副交感神经功能紊乱，已成为冠心病等心血管疾病重要的触发因素，可诱发各种心律失常、加重心肌缺血，甚至发生心源性猝死。1 O SAH S和高血压病探究发现，OSAHS患者夜间的微觉醒可导致交感神经兴奋性增强，肾上腺素能神经介质如肾上腺素、去甲肾上腺素分泌增多，夜间尿儿茶酚胺类物质增高。

Dehydroxylation, deoxygenation, and intake of oxygen ions from surface resulted in the reduction and oxidation of dopants in the bulk ZrO2 films.

But, this kind of condition would only occurred when a great deal of nitrobacteria are added into the water.

1去氨硝化菌能将鱼类所排放的氨转成毒性较小的亚硝酸盐，而去亚硝酸硝化菌则负责将亚硝酸盐再转成毒性更小的硝酸盐，硝酸盐必须由换水的方式移除，像硝化细菌这类的细菌再作用时需要消耗水中的氧气所以也称好氧菌。

The first synthetic route uses 1,2,4-trimethoxybenzene and chloroacetonitrile in forming 2,4,5-trimethoxy-a-chlor-acetophenone under the anhydrous condition, then the intermediate condensates with papaverine forming the core pyrro[2,l-a]isoquinoline, followed by formation and lactonization to form the lactone ring. The second synthetic route uses prepared aldehyde with prepared ethyl nitroacetate by Knoevenagel condensation to obtain 2-Nitro-3-(2,4,5-tris-methoxy-phenyl)-acrylic acid ethyl ester and 2-Nitro-3-(2,4,5-tris-benzyloxy -phenyl)-acrylic acid ethyl ester etal intermediates. The lamellarin skeleton could arise from condensation of the papaverine and these intermediates by Michael reaction, the ester group is provided for subsequent lactonization. The third synthetic route uses coumarin or indan-l,3-dione derivatives and papaverine to form lamellarin under basic conditions.

第一条路线首先从1，2，4-三甲氧基苯出发与卤乙腈作用合成卤代芳酮中间体，然后与罂粟碱反应合成开链片螺素，最后经乙酰化、去保护、成内酯环得到片螺素；第二条路线由制备的芳醛和制备的硝基乙酸乙酯经缩合得到2-硝基-3-芳基丙烯酸乙酯，然后由该中间体与罂粟碱反应，在完成关环的同时也引入酯基，最后去保护、成内酯环得到片螺素；第三条路线是由香豆素或茚二酮出发，经溴代后的中间体与罂粟碱反应，得到片螺素的基本框架。

Mr. I and plans for half a year want a BB but have not been pregnant this month to the hospital for an examination has been found pregnant as a result of six months but were not pregnant so there is no care to protect their early physical illness is as follows吃了药specific menstruation is the last time I was on the 4th to January 2 (can not recall the specific date that the last two days anyway) cycle for 29-32 days as a result of Kim Jong-January 16 Doctor hospital was opened two days of ofloxacin吊针two bottles a day and oral inflammation hundred net service for three days or not some of the symptoms also had oral Lowe four days after 28 No. Because when cooking large half fingernails cut off after two days due to inflammation of eating cefradine BB always wanted as a result of another failed as Friend introduction has been gradually taking ginseng cream until February 3鹿胎feeling some discomfort to the hospital post-mortem examination urine was very weakly positive on the drug problem at that time ask the director of hospital doctors when she helped me just as long as the operator told me to eat before February 5 in medicine are not all right to ask whether she was in the comfort me?

我和先生计划了半年想要个BB可是一直没有怀上这个月去医院检查验出已怀孕了可是由于大半年都没有怀上所以就没有小心保护自己身体早期因病吃了药具体情形如下我最后一次月经是一月二号还是四号来(具体日期记不起了反正就是这两天)周期为29至32天一月十六号由于泌感到医院看病医生开了两天的氧氟沙星吊针每天两瓶及口服药百炎净服了三天未还是有些症状又口服了洛威四天之后二十八号由于做饭时切掉大半块手指甲后由于发炎吃了两天的头孢拉定另外由于一直想要BB未果经朋友介绍一直在陆续服用人参鹿胎膏直到二月三号感觉有些不适去医院检查验尿呈极弱阳性当时就服药问题问了医院的主任医生当时她帮我算了算告诉我只要在二月五号前吃的药都没什么大碍的请问她是否在安慰我呢？

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
