Cavitation erosion is related to bubbles.Bubbles pop out from drilling fluid in vacuum conditiun and form air mass against cyclinder well.For low resistance to pressure,air mass happen explosion when compressed,making cyclinder wall cavitated.

气蚀发生的条件与气泡密切相关，气泡在真空时从钻井液中溢出形成气团，并紧靠缸壁；气团在压缩时因承压能力低而产生爆炸，从而引起缸壁产生气蚀作用。

Now I will cry like a woman in travail; I will gasp and pant at the same time.

42：14 我许久静默不言，忍住不语；现在我要喊叫像产难的妇人，我要急气而喘哮。

The results showed that enhancing monomolecular reactions could be favorable for increasing the propylene content in LPG, but the dry gas yield increased significantly.

结果表明，强化单分子反应有利于液化气中丙烯含量的提高，但干气产率也会同时增加；而一定程度上促进双分子反应，尤其是负氢离子转移反应的发生有助于抑制干气的生成，但程度太高时却不利于丙烯的生成。

The relationship between spectral line intensities from different species in the plasma and neutron yield and shot number shows that: with high neutron yield, the deuterium ionization degree is high; nitrogen and oxygen atoms are also ionized to a higher ionization state; electron beams emitted at the collapse time of plasma pinch column may cause strong electrode sputtering processes.

可见光谱中氘、金属材料Cu、Fe和空气成分O、N的原子或离子谱线强度与中子产额和放电次数的关系证明：中子产额高时，氘气的电离率高，N、O等杂质气体也被电离到高电离态，焦点箍缩柱崩溃时发射的强电子束可以引起强电极溅射过程。

Nitrate serves as a terminal election acceptor in Alcaligenes faecalis,when it grows anaerobically with lactate and ammonia as the carbon and nitrogen sources,respectively.

粪产碱菌生长在NH_4~+和NO_3~-两种氮源的介质中时，优先利用NH_4~+，在好气条件下，NH_4~+的存在抑制了粪产碱菌对NO_3~-的同化作用。

The main objective of this research project is to modify the Methyl-Acetylene/propadiene selective hydrogenation reaction system of the No.3 Naphtha Cracker in CPC. The original gas phase reaction system was redesigned to a liquid phase reaction so that higher propylene selectivity was achieved and lower rates of propane and green oil were produced. To recover effectively the higher production of valuable propylene from the reaction system, the following fractionator was also redesigned.

本研究之目的在於修改中油公司三轻工场老旧的甲基乙炔／丙二烯选择性氢化气相反应系统，使成为液相反应系统，藉由液相反应的优异性，提高由MAPD氢化得到丙烯之选择率，同时降低丙烷及绿油产率，以增加丙烯产率，另亦修改丙烯精馏系统，以提升蒸馏塔提纯之效率。

The influences of three instrumental parameters of ICP-MS spectrometer(radio frequenceypower, nebulization gas flowrate and ion lens voltage)on signal intensity and productivity of a few kinds ofions formed from 15 rare earth elements in the plasma(single element ions RE+,oxide ions REO+,hydroxideions REOH+ and hydride ions REH+)have been investigated.

研究了电感耦合等离子体质谱法的仪器主要参数(射频功率、雾化气流量、离子透镜电压)对15种稀土元素的离子、氧化物离子、氢氧化物离子和氢化物离子信号强度及各多原子离子产率的影响，并对各稀土元素多原子离子产率与各稀土元素性质的关系进行了探讨。

However, the presence of (NH4)2SO4 aerosols increased the semivolatile organic compound production by 36%, which may be attributed to the weak acidity caused by the interaction of (NH4)2SO4 with water-contained organic material.

CaSO4气溶胶的存在对SOA产率曲线没有明显的影响，而(NH4)2SO4气溶胶的存在使气相半挥发性氧化产物的生成量增加36%，显著地增加了SOA的产率。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
