In today's issue of the journal "Nature," scientists Flvia Nunes and Richard Norris describe how they examined a four to seven degree warming period that occurred some 55 million years ago during the closing stages of the Paleocene and the beginning of the Eocene eras.

在距今约5，500万年前，也就是古新世与始新世交替时期，地球曾有一段温度上升4~7度的暖化时期；而在最近一期《自然》期刊中，科学家那恩斯与诺瑞斯描述他们如何检验该时期的暖化效应。

If the method is combined with the subdivision method of curve,the rational spline curve with higher-order continuity is presented which is the approximation of offset curve.

By systemic researching and simulating experiment, the text gains such results as follows,1. On the base of sufficiency research on the oil-gas hydrocarbon systemic chemistry composing and the physical chemistry characters, we traverse the mechanism of the paraffin's deposition. Then we consider that paraffin deposition is a complex process ofphysical chemistry, which includes more than one single mechanism.2. Traversing and comparing the literature in detail on different factors that has effect on paraffin deposition, the available experimental methods on paraffin deposition, prevention of paraffin deposition, and removing of the deposited paraffin on the spot.3. Ameliorated the laser equipment of solid particle inspecting system and the corresponding test methods. Determine WCT of dead oil and live oil from KS101 well under different pressure with this system. The result implies that dead oil has opposite regulation on paraffin deposition temperature to live oil.4. A vapor-liquid-solid envelop is drawn by superposition regular vapor-liquid envelop and WCT curve thereby explained that the departure and quick raising of the curve in the low temperature zone is caused by the appearance of paraffin in solid phase.5. Estimation is made to determine the depth of paraffin deposition in the well.

通过系统的研究和实验模拟，本文取得了以下研究成果：(1)在充分调研油气烃类体系的化学组成及其物理化学特征的基础上，详细研究了石蜡沉降的机理，认为石蜡沉积是一个复杂的物理化学过程，是多种机理共同作用的结果；(2)深入调研并综合阐述了影响石蜡固相沉积的各种主要因素，对目前国内外常用的有机固相沉积实验研究方法和现场清防蜡措施也做出详尽的描述，并加以对比评价；(3)改进了油气藏开发重点实验室自行研制组装的高温高压下测定固相沉积的激光装置和测试方法，并用该套设备测定出柯深101井的井口脱气油样和凝析气平衡油样不同压力下的析蜡点，实验结果表明，脱气油和平衡油析蜡规律相反；(4)将常规气-液两相相图和析蜡曲线叠加得到了气—液—固三相相图，从而解释了气-液两相等液量线在低温区域偏离正常并快速上翘是由于体系有石蜡固相出现；(5)利用实验测试的析蜡温度预测析蜡位置，表明只有在距井口465m油管以上会有蜡析出。

Ofeffective 1st branches, length of main inflorenscence, effective siliques of maininflorenscence, density of main inflorenscence, length of silique, seed per sillique,1000 seed weight, total effective siliques per plant had significant positive correlationwith yield per plant. Polymorphisms between zhongshuang No.4 and H228 was examined by SSR primers. 152 primers Showed polymorphisms, and a linkage map containing 123markers, including 18 linkage groups was constructed. The total genetic distance ofthe map was 3483.1cM, and the average distance of two adjacent markers was28.32cM.

选用SSR引物对中双4号和H228间进行多态性检测，有152对引物在双亲间表现多态性，用这些引物分别对142个株系进行检测，构建了含有123个SSR分子标记、18个连锁群的连锁遗传图，总图距为3483.1cM，标记间平均距离为28.32cM，各标记在18个连锁群上的分布很不均匀，其中，第1、12、13、17连锁群上分布标记较多，其它连锁群上分布标记较少。
