查询词典 Pr

The higher amount of gammacerane, relatively low value of Pr/Ph (pristane vs. phytane) and presence of dinosterane all suggest that the lake during the period of Qingshankou 1st formation deposition was subjected to salinity stratification, strong reducing deposition environment, and the potential marine transgression. The shales of Qingshankou 2nd3rd formations mainly contain typeI and typeII kerogens.

青一段泥岩有机质类型主要为Ⅰ型，较高的甾烷含量反映以藻类输入为主，较高的伽马蜡烷和低的Pr/Ph及甲藻甾烷的存在反映该时期水体具有盐度分层和强还原的沉积环境，可能与海侵有关。

Cite a real case: In Baidu search netizen evil do Chen Guanxi to treat rank condition: Row the 1st be Baidu (this is not strange, stationmaster people know), ranking this station of the 2nd is Pr value is the dragon money net of 3 (0086money.com), row the 3rd it is me happy, platoon of the 4th is QQ.

Experiment and flow visualization are conducted in a water-filled cavity which cover the range of Ra=1×10〓----6×10〓 and Pr=3. 3---6. 5. Similarity theorem is applied in analytical investigations. And core region stratification effects to heat transfer are studied. By using scale analysis, temperature and velocity profiles in turbulent natural convection boundary layer are obtained. The results reveals that for turbulent natural convection in enclosures, the bulk of the cavity fluid is essentially statement with thermally stratified temperature and the only substantial motion is that in the boundary layer along four side walls.

Be such, to new website that still ranks data without Alexa, alexa is collected also have a process, like be just like search to all alone engine is collected, this needs period of time, specific how long is the thing of the specific algorithm inside Alexa, we are bad also and informal speak carelessly, but have a bit, if the visit amount of your station is large, meet what collect quickly for certain, still what Alexa ranks raise a question, the effective affirmation that brush a station can raise a rank, but Alexa rank also is an index that measures a website, collect an amount with Pr value and search engine, key word ranks the algorithm that there is his like waiting a moment, not be effect of 9 days of affirmative certain visibility, it is commonly of course should such, but what thing has exception, so, urgent also be urgent do not come, general left and right sides of a week, affirmative meeting vicissitudinous, if you are,undertaking brushing the word of the station effectively.

是这样的，对于新网站(还没有alexa排名数据的网站)，alexa收录也有一个过程，就好比搜索引擎收录一样，这个需要一段时间，具体多长时间就是 alexa里面的具体算法的事情，我们也不好随便乱说的，但是有一点，如果你站的访问量大，肯定会加速收录的，还有alexa排名的提高问题，有效的刷站肯定会提高排名，但是alexa排名也是衡量网站的一个指数，就和pr值和搜索引擎收录数量，关键字排名等等一样有自己的算法，不是一两天肯定就一定能见效果的，当然一般是应该这样，但是什么事情都有例外，所以，急也是急不来的，一般一个星期左右，肯定会有变化的，如果你是在进行有效刷站的话。
