In view of the rheological property of the heavy oil in Bo-hai field, this paper deduces the multilateral wells'production model of Non-Newtonian Bingham fluid with equiangular transformation method. In view of the multilateral wells Bo-hai, the paper analyses the multilateral wells'capitalized cost composition, including pre-drilling engineering, drilling engineering, completion engineering and production engineering. It also constructs the multilateral wells'economic benefit models basing on net present value, inner rate of return and payback period.

针对我国渤海油田稠油的流变特性，运用保角变换方法，推导了非牛顿Bingham流体的分支水平井产能模型；针对渤海油田的分支井，从钻前工程、钻井工程、完井工程、采油工程等方面对分支井的投资成本费用构成进行了具体分析；最后以净现值、内部收益率、投资回收期经济评价指标为基础，建立了海上分支井经济效益模型，并根据所建模型应用VB。

Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

To forestall any attempts at exegesis('Author, Citing Dadaism's Erstwhile Esotericism, Opposes Present-Day "Mamaist" Obfuscations'), I confess that as a title it means nothing at all; but then the very concept of meaning is now outdated, nerdy, pre-ironic.

To forestall any attempts at exegesis ('Author, Citing Dadaism's Erstwhile Esotericism, Opposes Present-Day "Mamaist" Obfuscations'), I confess that as a title it means nothing at all; but then the very concept of meaning is now outdated, nerdy, pre-ironic.

为了免去注释的麻烦（作者，引用达达主义的早期深奥主义，与现在的实际主义者的困惑相反），我承认，作为题目它毫无意义；不过，"意义"的概念如今已是过时、卑微、且极具讽刺的。
