If we plug the current consensus estimate of Q1 GDP growth and then compute the year-on-year four-quarter percentage change, we get a figure of -2.3%. Thus, based on consensus estimates of GDP for Q1 2009, the four-quarter contraction of GDP will be--in the first quarter of this year--already worse than both the baseline scenario figure （-1.9%） and the more adverse scenario figure （-2.1%）.

然而，根据上述环比增长-5%的主流预测值计算，1季度GDP的同比增长率应为-2.3%；这就是说，即使是在1季度，主流预测的GDP同比增长率就已低于压力测试中假设的基准情形（-1.9%）和悲观情形（-2.1%）的数字了。

Firstly, with the analysis of electric characteristics of a condensate gas reservoir, we find that there are some differences between Tri\|porosity logging amplitude, Deep Investigation Laterolog, Shallow Investigation Laterolog, and Microlaterolog, etc; secondly, in view of the feature of the condensate gas reservoir, the log interpretation model is built on the basis of the correlation of four reservoir parameters, and the reservoir grade scale is completed using conventional logging techniques combined with cross plot technique and the result of well testing; finally, according to the feature of Qiketai Formation and Sanjianfang Formation in the Hongtai oil field, we set up the reservoir classification criteria and divide the reservoir parameters into four types.

以吐哈盆地红台地区为例，对凝析气层的电性特征进行了分析，认为凝析气层在三孔隙度测井曲线幅度和深、浅、微电阻率等方面存在差异。针对研究区凝析气藏特点，在关键井&四性&关系研究的基础上，建立了储层参数测井解释模型，采用交汇图技术和实际试油、试气资料相结合的方法，对研究区目的层常规测井储集层的分类标准进行了分析，并结合红台气田七克台组和三间房组凝析气藏特点，建立了研究区储层参数分类评价标准，依据该标准将红台地区储集层划分为4类。

A two-year field experiment was conducted to investigate ammonia volatilization from Gleyed paddy soil in the Taihu Lake region. The experiment was designed to have four N levels 0, 180, 255, 330 kg hm^(-2 and four P205 levels 0, 30, 90, 180 kg hm^(-2, forming six NP combinations (CK-N0P0, LN-N180P90, OPT-N255P90, LP-N255P30, HP-N255P180 and HN-N330P90). Ammonia volatilization was measured with the enclosure method.
