, 2012 本文对真空隔热油管的隔热性能主要影响因素及失效机理进行了分析,并提出了改善隔热性能与延长使用寿命的解决思路。保证隔热层具有一定的真空度是维持隔热油管隔热性能的核心,氢气渗透、管材气体脱附、油管机械破坏等因素都会使得隔热层真空度下降,减弱隔热性能。氢气主要来源于钢材的析氢腐蚀和原油裂解等。本文根据对隔热性能主要影响因素的分析提出了一些解决思路,以期减缓其隔热性能下降速度,延长隔热油管使用寿命 ...

Shiyou jixie, 2012 稠油热采新工艺应用中前期先导试验时采用光油管注汽，出现注汽热效率低、部分井套管和固井水泥环被破坏等问题。为此，研制了Y341-115热采封隔器等配套工具。配套工具与井筒隔热技术相结合，使浅薄层稠油油藏得到了有效动用和开发。此外还根据现场工艺管柱的特点，配套开发了张力油管锚、大流道单流阀等工具，解决了隔热和反洗井等问题，实现了隔热注采合一的功能。Y341-115隔热封隔器配套工艺技术现场共应用500多井次，其工艺成功率达98%以上，累计节约作业井次400多次，累计增加产油量8 312 t。

耐热型巧克力的口溶性感官评价及其量化研究Oral sensory evaluation of heat-resistant chocolates and their quantization
Zhongguo youzhi旨在为耐热型巧克力感知科学的研究及其配方和工艺调整提供参考，以芒果仁油分提硬脂制备的典型耐热型巧克力为研究对象，以硬脆感、冰凉感、油脂味、黏稠感和后味感为评价指标进行口溶性研究，并测定耐热性巧克力的质构，采用多元线性回归分析其口溶性感官评价指标与质构指标的关系，建立量化方程。结果表明：耐热型巧克力的口溶性感官总得分与可可脂基巧克力接近，口溶性理想，具备丝滑的口感，但细分口感指标略有不同，耐热型巧克力的硬脆感和黏稠感增加，而冰凉感、油脂味和后味感降低；多元线性回归分析显示，硬脆感、黏稠感和后味感与硬度 ...
