转化率

Summed up an experience to what we make network sale so, must not regarding SEO as is the only work of network sale, SEO has been done really the effect is very apparent, your cause client the finds you through searching engine website with can special accurate spirit, change rate is average taller, the ad that more beautiful than you even money buys is changed rate is even high, and the can very good product network brand that promotes you, but his turn a sex changeably too strong.

这样给我们做网络营销的总结了一个经验，千万不要把SEO当成是网络营销的唯一工作，SEO做好了的确效果非常明显，你的目标客户都能非常精准的通过搜索引擎找到你的网站，转化率一般都比较高，甚至比你花钱买的广告转化率还要高，而且能很好的提升你的产品网络品牌，但他的可变化性太强了。

From the point view of product distribution, conversion of dimethyl ether and energy consumption, with RCD plasma DME conversion was higher and was hardly affected by the residence time of dimethyl ether, and hydrogen, carbon monoxide and unsaturated hydrocarbons with RCD plasma were more than those with DBD plasma.There was no liquid product with RCD plasma, but the liquid product obtained with DBD plasma consisted of aldehydes, alcohols and methoxy-containing organic compounds, for instance, formaldehyde, methyl alcohol, dimethoxy ethane and so on.Moreover, most compositions of liquid product were methoxy-containing compounds, and the liquid product selectivity was as high as 32.23%.However, energy consumption for the reaction with DBD plasma was more than that with RCD plasma.

从产物分布、转化率及能耗上看，利用RCD所获得的二甲醚的转化率高，几乎不受二甲醚停留时间的影响，且氢气、一氧化碳和不饱和烃的含量大，几乎没有液相产物，而利用DBD能获得较多的液相产物，包括一些醇、醛和含有甲氧基的有机化合物，如甲醛、甲醇和二甲氧基乙烷，且大部分组成都是含有甲氧基的化合物，液相产物的选择性高达32.23％，但是能耗较大。

The results show that among the acetoacetonate complexes,Co_3 has the best catalytic activity.The optimum reaction conditions were as follows:0.764 mmol of Co_3,mole fraction of ethanal 10%based on the substrate,room temperature,oxygen pressure 2 MPa,reaction time 11h and solvent acetonitrile.Under these conditions,13.3%p-chlorobenzaldehyde was obtained with 15.3%conversion and 87.2%selectivity.The oxidation can also be carried out without solvent with 8.1%conversion,89.1%selectivity and 7.2%yield respectively.

在金属配合物中Co_3的催化性能最好，在其用量为0.764 mmol、乙醛用量为反应物物质的量的10%、氧气压力为2MPa时，以乙腈为反应介质，室温下反应11h，反应的转化率和选择性可达15.3%，87.2%，对氯苯甲醛收率可达13.3%；反应也可在无溶剂时进行，此时反应的转化率、选择性及醛的收率分别为：8.1%，89.1%，7.2%。

The temperature and the addition of surfactant can accelerate conversion and selectivity of reaction. Under the conditions of 200℃、0.38MPa、0.06 mol/L、t=4h,the conversion of hexene is 86.32%.Selectivity of 2-hexene and 3-hexene is 30.46% and 57.86%.

结果表明，当表面活性剂的加入以及反应温度的升高，能明显提高反应的转化率和选择性，在200℃、0.38MPa、0.032 mol/L的反应条件下，反应4小时底物转化率为86.32%，3-己烯的选择性为57.86%，2-己烯的选择性为30.46%。

Long time hygrothermal ageing may have significant effects on the structure of the blend when the cure extent is not sufficiently high.

表观转化率提高，则吸湿性降低；固化程度越大，湿热老化对化学结构影响越小，但当固化转化率不高时(例如小于 90 %)，湿热老化可能对共混物结构产生显著影响

Result shows that the sulfur compounds in the diesel can react with iodomethane easily at room temperature, the most of sulfur compound derived into methylsulfonium salts; the homologue of benzothiophene get the higher conversion ratio and react selectivity than the homologue of dibenzothiophene. It is found that primarily sterically hindered alkylated DBT, for example, 4-or 4-, 6-DBT, is recalcitrant to be methylated.

结果表明：柴油中硫化物在室温条件下容易与碘甲烷发生甲基化反应，大部分硫化物转化为锍盐，总转化率超过80%，苯并噻吩类比二苯并噻吩类更易发生甲基衍生化反应，转化率也相应较高。

A sort of lipase producing strain with relatively high esterification rate of ethyl hexanoate was obtained was isolated from Lavandula vera L. root soil. The strain was identified and named as Arthrobacter Y-605. The optimal lipase producing conditions of the strain was indicated in details and the results were as follows:2% maize meal, 1% soy flours, 0.1% urea, 0.05% MgSO4, 0.1% K2HPO4, 0.15% KCl.

以有机相中合成酶活为指标，通过对薰衣草根际土壤产脂肪酶菌株的筛选，获得了一株在有机相中合成己酸乙酯转化率相对较高的细菌Arthrobacter Y-605，其己酸乙酯转化率为67.53%。
