Based upon a thorough investigation of national rubber oil market , the author adopts the theory of market individualization and target market option , and decides that liaohe lube oil plant should involve in the competitive target market . the author uses porter ' s five competitive power model and analyzes and studies the structure of target market and the major competitors . then the author adopts swot analysis method to study the advantages and disadvantages of liaohe lube oil plant as well as the opportunities and threats 作者在深入调查研究全国橡胶油市场现状的基础上，采用市场营销学的市场细分与目标市场选择理论对全国橡胶油市场进行了细分，确定了辽河润滑油厂应参与竞争的目标市场，继而运用波特的五种竞争力量模型分析研究目标市场中的行业结构，并重点分析了主要竞争对手的情况，然后采用swot分析法研究辽河润滑油厂相对于竞争对手的优势与劣势及目标市场环境中的机会与威胁，最终采用一般性竞争战略理论，确定辽河润滑油厂应采取的橡胶油市场竞争战略。
We research the causes of concrete cracking , develop the high performance anti - cracking additive , optimize the concrete mix and construction techniques , increase the stability of concrete volume by shrinkage compensation , enhance splitting tensile strength , and can meet demand of high workability of fresh concrete . . in the study , a thorough investigation of this problem is made from all points of view , with the aid of various modern measurement & testing technology and different theories & methods in surface physical chemistry , structural chemistry , solid - state chemistry , composite materials , fracture mechanics , etc . our research results have shown that the various shrinkage of concrete cause concrete cracking in building engineering , such as autogenous shrinkage , dry shrinkage , temperature shrinkage , plastic shrinkage , carbonized shrinkage , etc 目前，解决混凝土开裂的方法是综合的，我们调查研究了混凝土开裂的原因，开发研制了高性能抗裂外加剂，优化混凝土的设计和施工方法，并通过补偿收缩达到混凝土体积稳定，提高抗裂强度，满足混凝土拌和物高工作性能的要求。本研究采用多种测试技术，应用表面物理化学、结构化学、固体化学、复合材料学、断裂力学等多学科的理论与方法，从不同的角度进行深入的研究和探讨。通过调查研究建筑工程中出现的混凝土开裂、渗漏问题，发现混凝土在非荷载作用下开裂主要是由混凝土的自收缩、干燥收缩、温度收缩、塑性收缩、碳化收缩等各种收缩变形引起的。
As according to these and aiming at the practice , considering the fact from tap interprise and science and technology , fund external invioroment . to make a thorough investigation and study from foreign experience for reference and draw our conclusion so that put out a series ways to deal with the situation : each does his best in interprise construction . and multi wheels to push investment 定性分析与定量分析相结合以及横向对比分析等研究方法，针对吉林省实施农业产业化过程中面临的龙头企业、科技、资金、外部环境等突出问题进行深入分析，借鉴国外的一些先进经验和做法，提出了在龙头企业建设上各尽所能、投资上多轮驱动和外部环境建设卜重在体制转换等一系列对策。
Based on a thorough investigation on positional variances of quality control points of jacket , absolute error ellipse and relative error ellipse , which can show the precision of quality control points of jacket in any direction , are presented and then applied to quality control of jacket 在对质量控制点的点位方差进行深入研究的基础上，给出表示导管架质量控制点在任意方向上精度的绝对误差椭圆和相对误差椭圆，进而将这两种误差椭圆应用于导管架的质量控制中，从而使导管架的质量控制更有效和准确。
