The fogged value before fatliquoring depended on the types of raw hide and skins, beamhouse and tanning method, and its value had some influence on the fogged property of finished fur, but did not impact the sequence of fog property for fatliqouring agent.

加脂前毛皮雾化值的高低取决于原料皮的种类、鞣前准备和鞣制方法，其值的大小对毛皮成品的雾化性能有一定影响，但并不影响加脂剂对毛皮雾化性能的影响次序。

Proliferating cell nuclear antigen is usually regarded as anindex of determinating cell proliferating and its expression levelin the nuclear is correlated with with the activity of cellproliferation. The activity of tumor cell proliferation can beknown by examinationing PCNA of tumor cells.

增殖细胞核抗原(proliferating cell nuclear antigen，PCNA)常作为测定细胞增殖水平的指标，其在细胞核内阳性表达的高低与细胞增殖活性密切相关，通过检测肿瘤细胞的PCNA ，可了解和评价肿瘤组织的增殖活性。

Moreover, there came also "Midnight" by Mao Dun,"Luo Tuo Xiangzi" by Lao She and "Biography of Hulan River" by Xiao Hong (The writer from the northeast of China). Put aside the questions like if the artistic contribution of those work is big or small, or if those writers have conceptualized the word of "bottom", while the debate about this belletristic conception hasn't been settled for a long time.

鲁迅的杂文，蒋光慈的诗歌，丁玲、叶紫的小说，还有茅盾的《子夜》，老舍的《骆驼祥子》，东北作家群里萧红的《呼兰河传》以及沈从文的&湘西小说&等等，不谈这些作品的艺术高低，也不谈作家们是否将&底层&概念化，反正这个纯文学的问题从以前争到了今天一直没有定论，且放一边。

Study the result makes clear, content of Potassium of quick result of soil of area of high yield wet earth is 287.476gkg-1 on average, highest for 483.433gkg-1, lowest is 119.435gkg-1, bulbiform model is Potassium of edaphic quick result the optimal model that successional space distributings, its gold nugget is worth / floor sills value is 0.399, potassium of demonstrative soil quick result is changing the dimensional variability that Cheng has moderate strength inside the limits for 57.691 meters, the area of content discretion distributings more apparent, in the southeast of plot the ministry is mixed mid it is the area with its higher content, two content is inferior outstanding area show typical circle layer to distributing, increase by degrees by the content outside introversion, have stronger gradual change sex to distributing the rule.

探究结果表明，高产潮土区土壤速效钾含量平均为287.476gkg-1，最高为483.433gkg-1，最低为119.435gkg-1，球状模型是土壤速效钾连续性空间分布的最佳模型，其块金值/基台值为0.399，说明土壤速效钾在变程为57.691米的范围内具有中等强度的空间变异性，含量高低的区域分布比较明显，在地块东南部和中部为其含量较高的区域，含量较低的两个突出区域呈典型的圈层分布，由内向外含量递增，具有较强的渐变性分布规律。

Their adsorption rate on the molecular sieve catalysts surface and the stability of their carbonium ions were then obtained based on the molecular simulation on these molecules from their dipole moment, 2-dimensional electrostatic potential energy contours and 3-dimensional electrostatic potential energy isosurface.

采用半经验的AM1量子化学计算方法和静态理论，分别考察了噻吩、 3 甲基噻吩和 2 ，5 二甲基噻吩分子结构特性的不同，从偶极矩、各自垂直于芳香环平面的二维电势能分布曲线和整个分子周围三维电势能分布情况等方面分析了它们在分子筛催化剂表面吸附速度的快慢和生成正碳离子稳定性的高低，进一步比较了噻吩及其衍生物所生成的正碳离子进一步反应的能量变化，从而可判断噻吩及其衍生物裂化脱硫速度的快慢，噻吩及其衍生物裂化脱硫的速度由大到小分别为：2 ，5 二甲基噻吩、 3 甲基噻吩、噻吩。
