常到

In order to optimize the spring of the reciprocating pump valve and establish the best spring factor matching, the unsteady opening-closing process of the poppet valve was simulated. The simulation based on computational fluid dynamics approach, and the dynamic-grid technology and User Defined Function was conducted to depict the law of motion of the poppet valve.

采用RNG k-ε湍流模型、动网格技术以及用户自定义程序，对往复泵泵阀的启闭过程进行了非定常数值仿真，得出了不同弹簧因素下、阀门从开启到关闭的过程中，阀芯的升程随时间的变化规律、阀的迟滞关闭时间以及阀芯落座的瞬时速度。

I often buy flowers, so I can also share some experiences of flower peddlers.

常去买花，因此也常常能分享到花贩的经验。

Farina doesn't appear often in the strip, and as such Pastis is forced to reintroduce her every time she appears (from The Crass Menagerie ; Pastis said in Sgt. Piggy's Lonely Hearts Club Comic that part of the reason why he doesn't draw her as often is because she is the only character who requires a drafting compass to draw and he usually cuts himself using it).

菲丽娜不常在漫画中现身，因此在她每次出场的时候帕斯蒂斯都不得不再介绍一遍（在《粗鲁动物园》中；帕斯蒂斯说在《小猪中士的交友俱乐部》中他不画皮姬塔，有一部分原因是她是唯一一个需要用圆规画的角色，而帕斯蒂斯在用圆规的时候经常会刺到自己。

The SBT thin films with STO seeded layer on MFIS structure also appear prefer (115),(006) orientation and good crystallinity. The seeded layer of STO effectively resists the diffusion of Bi into Ir bottom electrode on MIM structure. The remanent polarization and leakage current density of Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layers are significantly improved. In MFIS structure, the Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layer are improved memory window and lead to lower leakage current at low voltage.

在具有STO晶种层基材上沉积之钽酸锶铋铁电薄膜於700℃淬火后，无论在MIM和MFIS结构上皆可得完美(115)方向之SBT结晶相，而STO的种晶层在MIM结构中确实可以有效的阻止铋原子扩散进入底电极，而降低漏电流，在MFIS结构中虽然得到一较小极化值，但由於铁电层所分配到的电场值反而因介电常数值降低而增加，因而得到较大的记忆窗。

Sunset in the Arctic Circle, the breeze through the valley and the evergreen forest...Such spacious views appear in your mind out of focus, with no specifics for any imaginations, just from a far country, Norway.

北极圈内苍白倾斜的阳光，漫过清寒微风的山谷、常绿的寒带茂密丛林……挪威，如此遥远的国度，遥远到你脑海里只有这样一些旷远而模糊的图画，而没有关于它的任何具体的细节想像。

Vacuum transfer line is one of the most important pipelines of atmospheric vacuum distillation plant which starts from the exit of heaters and extends to entrance of distillation tower.

减压转油线是炼油厂常减压蒸馏装置中加热炉出口到蒸馏塔底入口的管道，它是炼油装置中最重要的管道之一。

He also said he did not like the company, and requested for transfer to another company that he had picked out.

他常说不喜欢公司，并要求把他送到其他公司。

The drive means delivery the Sheung Moon Box from one starting point to another end point.

5，运送次数是以每次车程作计算，车程是指一个起点送常满储物箱到一个终点。

Hubris, however, has been followed by nemesis rather too often in this field for anybody to be making a song and dance about things

不过，在这领域狂妄自大太常招到报应，以致于没人敢对这样的事手舞足蹈。

High quality total RNA were isolated from adult chicken's liver organ of four chicken breeds: silk fowl , normal plumed black-bone chicken , SuQin 96 layer chicken and Abar acer meat chicken . The differential expressed genes in liver organ of above chicken breeds were studied via DDRT-PCR technique for the first time.

本试验成功地从丝羽乌骨鸡、常羽乌骨鸡、苏禽96型蛋鸡以及爱拔益加肉鸡的成年鸡肝脏组织中提取到质量较高的总RNA，首次采用DDRT-PCR技术对四个家鸡品种肝脏中差异表达的基因进行了研究。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
