去饱和

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.

The significant improvement might be caused by the Cu substrate which has higher thermal conductivity than conventional Sapphire substrate. However, Cu substrate is a ductile metal plate and easy to deform during the processing. The deformation of the Cu substrate will destroy the LEDs that were bonded on the Cu substrate. Finally, LEDs will be fabricated on the patterned Cu/Si substrate to make high-power LEDs and solve the deformation problem in processing.

主要是因为利用铜基材去取代蓝宝石基板使其具有较高的散热性，可以使元件在较高的饱和电流下驱动以达到高功率的目标，然而，铜金属是延展性佳的材料，因此，在整个元件的制做过程中，易造成发光二极体元件毁坏，利用本实验的方法可以提升制造高功率发光二极体之良率。

But the network cable version you can sample locations to observe the master, while non-net site is rarely used instruments to its seriousness, adjusting the pressure by our own experience, as well as on non-net business card printing and membership card making products paid enough attention to, as long as the field without a saturated color deficiency, there you go, so adjust to stress that, in some cases this is a standard printing efficiency (probably as a result of ink, paper causes), the largening business card printing and membership card making pressure so that it reaches collesting burliness, color saturation, which in English means offsctdruckereien stress damage without, in particular affect printing quality.

但网线版可以堵住不不差样弛的网不面来查察把持，而无网实不天则好众用仪器去检测它的不弛辛，调动水平不常凭自己的教训，同时也不不差无网制卡和会员卡制作品不敷鄙薄，觉得只给印不入实不天不不收虚，色彩较饱和不离可以了，因此不不差不弛辛的调动也不离以此为尺量，有时印品成果不佳(不定是因油不朱、纸弛来因造不败)，则拔取加不小制卡和会员卡制作不弛辛的办法，使之到达实不天单弱，色彩饱和的成果，殊不知胶印不弛辛功不小有百害而无一利，格外会感化印品格量。

It is a testimony to the joyfull pull of family that Americans saturated the air and highways this week to return to the place they no longer live but nevertheless call home.

对这个充满了欢快的回家乡度假的家庭来说，有证据表明这周美国的去他们虽然已不再居住的家乡的航空和公路运输都已饱和

The adsorptive effect of chitosan on acidic dye follows a sigmoidal trend. The chitosan-woven fabric after 98% de-acetylation achieved 98% and 95% dye adsorption in reactive dyes; and achieved 93% and 92% dye adsorption in reactive dyes in eight days. The higher the degree of de-acetylation, the better the dye adsorption.

使用去乙醯化98%的几丁聚醣含浸织物吸附材，在经过8天的饱和吸附后，对於种反应性染之吸附效果可达到98%和95%；且对於种酸性染之吸附效果也可达到93%和92%，由此可知去乙醯化程越高，对染的吸附效果越好。

WT, antisense-transgenic lines T2-8 and sense- transgenic lines T2-7 of tomato were used to measure the fatty acid composition of thylakoid membrane, photosynthetic and chlorophyll fluorescence parameters, chloroplastic reactive oxygen species and activities of antioxidant enzymes under salt stress.

以野生型，转反义番茄叶绿体ω-3脂肪酸去饱和酶(LeFAD7)基因株系T2-8和转正义LeFAD7基因株系T2-7为试材，测定了类囊体膜脂脂肪酸组成，盐胁迫后的光合参数，叶绿素荧光参数和叶绿体活性氧清除酶活性。

The next step is to desaturate the layer that will take on the bloom effect.

下一步是对图层进行去饱和，图层将获得辉光效果。

Elderly patients are more prone than younger patients to developcerebral desaturation because of the reduced physiologic reservethat accompanies aging .

随着年龄的增长老年病人生理储备下降，因此比年轻人更容易发生脑氧去饱和。

The risk of respiratory complications (i.e., desaturation, cough, laryngospasm, bronchospasm, breath-holding, or apnea) and wound infection (i.e., wound redness or discharge +/- positie microbial culture, requiring antibiotic therapy) in smokers nonsmokers was ascertained.

作者查明了吸烟者和不吸烟者发生呼吸系统并发症（例如：去饱和作用，咳嗽，喉痉挛，支气管痉挛，憋气或者呼吸暂停）和伤口感染（如伤口红肿，或是渗出液细菌培养阳性，或需要抗生素治疗）的危险性。

The results indicated that whole H-OLE1 gene could complement fad1 mutation in H. polymorpha recipient lacking △9-fatty acid desaturase. However UFA requirement that Saccharomyces cerevisiae ole1 mutant displays was complemented only by ORF of H-OLE1 driven by S.

发现完整的H-OLE1基因可互补缺乏△9-脂肪酸去饱和酶活性的多形汉逊氏酵母营养缺陷型fad1突变体，却不能互补相应的酿酒酵母ole1突变体，而由酿酒酵母GAP表达框架和H-OLE1 ORF组成的嵌合基因可互补上述ole1突变体。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
