甲醇

It is also true that Drosophila melanogaster, which does not methylate its genome, suffers a very high rate of spontaneous mutations—from 50% to 85%—through the action of transposable elements.

这也是事实果蝇，而这还不甲醇，其基因组中，出现了非常高的自发突变，从50 ％至85 ％-透过行动的转座因子。

The processes of repeatinduced point mutation and methylation induced premeiotically, both found in fungi, and of repeatinduced gene silencing, found in flowering plants, all silence and methylate repeated sequences, a common characteristic of parasitic DNA elements.

过程repeatinduced点突变和甲基化诱导premeiotically ，均发现真菌，并repeatinduced基因沉默，发现在开花植物，所有的沉默和甲醇重复序列，一个共同的特点，寄生虫的DNA分子。

The influences of reaction conditions such as material ratio, reaction temperature and time were studied.The optimum preparing condition was that the mole ratio of 1,3-diiminoiso- indoline and trimethoxysilane was 4:3,sodium methylate and tributylamine as additive ,reaction time 11h at 220℃, the yield of metal-free phthalocyanine was 46.7％.

并对反应时间、反应温度、原料配比等影响因素进行了研究，优化了工艺条件，得到的最佳反应条件是在酞菁素和三甲氧基硅烷的摩尔比为4：3，甲醇钠和三丁胺为添加剂，于220℃反应11h，无金属酞菁的最高收率为46.7％。

According to our method, we can quantify the total amount of isoflavone more rapid and conventiently without preparing all 12 kinds of standards.In this study, acetyl- and malonyl- glycosides were converted to 7-O-glycosides by reacting with 1M methanolic sodium methylate at 60℃ for 20 min. Then, the solution was neutralized with 2.5N HCL and extracted for further 30 min at 60℃. Aglycones and 7-O-glycosides were then analysed by HPLC.

根据本研究，此方法系使用1.0 M sodium methylate在60℃下与样品中之acetylglycoside、malonylglycoside反应20分钟，将其转化为7-O-glycoside，反应完成后以2.5N盐酸水溶液中和，调整溶液为80%甲醇溶液并在60℃下继续萃取30分钟然后进行HPLC分析；由於仅需要分析两种形式的大豆异黄酮化合物（aglycones及7-O-glycosides），因此可以有效地缩短分析时间至30分钟以内。

The steps were as follows: trimethyl borate-10 was synthesized from boron-10 trifluoride-ether complex and sodium methylate,which was hydrolyzed to synthetize boric-10 acid.

首先采用三氟化硼-10-乙醚络合物与甲醇钠反应生成硼-10酸三甲酯，之后水解合成硼-10酸。

Magnesium methylate can be prepared by reacting magnesium with dry methanol; Primary alcoholates can be prepared by alcoholysis; the sterically demanding substituted magnesium alcoholates can be prepared by ester exchange or from dialkylmagnesiums.

综上所述，几乎所有的醇镁化合物都可以通过这三种方法进行制备：甲醇镁通过直接合成法制备；伯醇镁通过醇解法制备；仲醇镁或叔醇镁通过酯交换或烷基镁法制备。

The synthesis path of 2-phosphono-butane-1,2,4-tricarboxylic acid is studied by using alkyl phosphate,butendioic acid dialklesters and methyl acrylate with the catalyst of sodium methylate.

论文摘要本文以亚磷酸二甲酯，顺丁烯二酸二甲酯，丙烯酸甲酯为原料，甲醇钠为催化剂，合成了 2-膦酸丁烷-1，2，4-三羧酸并对中间物及产物进行了 IR、13C，31P 核磁，MS 表征。

Silicon phthalocyanine dihydroxide was prepared from silicon phthalocyanine dichloride through two methods. The first was alkali treating that meaned silicon phthalocyanine dihydroxide was treated in the ethanol solution containing sodium methylate .The second was acid treating meaned precipitating its solution in concentrated sulfuric acid into ice water. The product yield of the second method was 77.0％, which was higher than the method of alkali treating.

此外将合成的二氯酞菁硅采用两种方法转化为二羟基酞菁硅，第一种方法是碱处理法即将二氯酞菁硅在甲醇钠的乙醇溶液中回流得到，最高收率为53％第二种方法是酸处理法即采用二氯酞菁硅的硫酸溶液在冰水析出的方法转化为二羟基酞菁硅，其中酸溶析出法收率为77.0％。

Sodium Methylate.

甲醇钠。

This test can also be completed by mixing equal parts honey and methylated spirits. Pure honey will settle to the bottom.

这个实验也可以通过把蜂蜜和加了甲醇的酒精等量混合的方法来完成。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
