查询词典 rop

Due to the increasingly deep concerns about the cytotoxicity of stannous octoate, which is the most widely used catalyst for synthesizing polyesters derived from lactides (L-LA, D, L-LA, GA) via ring opening polymerization, a lot of new metal complexes of relatively low toxicity including Schiff base–Al complexes, Red-Al were developed and used to initiate the living, stereo-specific, and/or stereo-selective ROP of lactides.

由于合成聚乳酸类生物医用降解材料的最常用的催化剂辛酸亚锡 Sn2的细胞毒性问题已在世界范围内引起日益深切的关注，近年来国内外学者已研究开发出许多性能优异的低毒、非锡金属络合物催化剂（如：位阻西佛碱-Al 络合物， Red-Al 等）用于催化交酯类单体的活性、立构专一性及立构选择性聚合反应。

To control deviation, the actual WOB is usually adopted in the lower range, which results in ROP increasing is unconspicuous and predominance of gas drilling can't be showed.

在实际气体钻井过程中，为了控制井斜，通常都将钻压控制在较低的范围内，这就导致气体钻井提高机械钻速不明显，不能充分发挥气体钻井的优势。

As for the air percussive rotary drilling, because of its advantages of high ROP, long bit life, light WOB, reduced wear of drill collar, large cuttings, low drilling cost, low formation damage and no lost circulation, it has gained acceptance.

空气冲击回转钻井在一些特定的地层和井眼条件下具有高机械钻速、长钻头寿命、小钻压、较轻钻具磨损、大岩屑、低钻井成本、较轻油层污染和避免井漏等优点，因此很早就被钻井界接受。

Often, only part of the retina detaches.

如果ROP的治疗没有发挥作用，那么也许会发展到视网膜脱离，一般来说，只是一部分的视网膜脱离（第4阶段）。

The draft of Civil Law by legislators and the advice toCivil Law by scholars, based on the basic p rincip les in Chinese General Rules of Civil Law, have exp ressed differently in terms of the basic p rincip les. But it is app rop riate to establish the p rincip les of equality, voluntaries, honestand credibility, public order and good habits, p rohibition of civil right abuse as the basic p rincip les of China's Civil Law.

在我国《民法通则》规定的民法基本原则的基础之上，民法典官方草案及主要学者建议稿对于民法基本原则采用了有所差异的不同表达，但将&平等&、&意思自治&、&诚实信用&、&公序良俗&和&权利不得滥用&确定为我国民法基本原则，较为妥当。

So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closedloop rotary steering drilling system AUTOTRAK, highperformance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the highside to reliably stick out against the upper wellbore.

为提高机械钻速，引进贝克休斯的VTK垂直钻井技术，它是由AUTOTRAK、高性能X-TREME马达、可靠的MWD三种技术开发出来的一种闭环自动垂直钻井技术，能够根据井眼的偏斜，经井下微处理器分析判断，使导向稳定地靠近井眼高边方向导向肋板伸出顶向上井壁，这样使钻头产生合理的降斜力，从而使井眼回到垂直轨道上来。
