    如果鍋爐沒有關閉截止止回閥，則必須防止迴流到鍋爐上，閥瓣壓鐵和緩沖活塞，在重力的作用下，能夠迅速實現密封，使得蒸汽和冷凝水即使在低壓下也不會迴流到鍋爐里。
  2. For electrodeposition by dc methods, the metals deposite uninterrupted and the particles were also embeded uninterrupted into the coatings ; for electrodeposition by pc method, the particles with biggish volume were desorbed from the coatings and returned to the electrolyte again owing to the presence of pulse interval ; for electrodeposition by prc method, the particles carried positive charges are much more easy to desorb from the coatings owing to the effecf of reverse pulse current combined with pulse interval, in addition, the reverse pulse current also could dissovle the metals, further accelerates the desorption of particles, thus the particles size embeded in the coatings by prc method is the least

    直流電沉積時，基質金屬的沉積連續進行，粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附，重新回到溶液中;採用周期換向脈沖時，反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附，同時，反向脈沖電流對基質金屬的溶解作用，也會促進粒子的脫附，因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加，三種鍍層的晶粒都明顯細化，說明al _ 2o _ 3的存在阻止了晶粒的長大，提高了電沉積過程中晶核的形成速率。
  3. By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves, it was found that there was intense turbulence in the flow fields around fixed - valve, there were eddy areas between valve side orifices and tray wall, there were eddies above the valves too, these led to the complex behaviors of gas perforating valve, these had a great effect on the gas - liquid mass transfer process. at the same time, in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer, it was very effective to change the fields of gas perforating valve by folding the edges of valve

    通過對數值模擬得出的單閥和雙閥塔板的干板壓降及流場速度分佈分析對比后發現，固定閥周圍流場存在較強的湍動，閥側孔與塔板壁面區域以及閥體的上方空間存在明顯的渦流區，使氣體穿閥后的行為變得復雜，並對氣液傳質過程產生重大影響；模擬結果表明，為防止和削弱固定閥間的對沖造成的「死區」對傳質帶來的不利影響，通過折邊來改變氣體的氣路是非常有效的，模擬值與實驗值基本得到吻合。
  4. Finally, due to the rapid rotation of the neutron star, or the evolution of the companion, the infall of matter stops, the x - ray emission declines, and the neutron star emerges as a radio - emitting millisecond pulsar

    最後，由於中子星疾速的自轉，或是伴星自身的演化，物質的流入停止， x射線輻射減弱，這顆中子星就呈現出了毫秒脈沖星的面目。
  5. Although the people s bank of china has been issuing quite a lot of short - term paper to " sterilise " the capital inflow, in other words to try to slow down the increase in the aggregate balance, or prevent it from increasing, the banks must have still found themselves holding increasing amounts of money in their clearing accounts with the people s bank, to the extent of being able to accommodate rapid increases in loan demand

    就此，中國人民銀行人行發行了不少短期票據，以沖銷流入的資金，亦即是說嘗試阻止總結餘繼續增加或減慢其增加速度。然而，銀行在人行的結算戶口的結餘仍在不斷上升，足以讓銀行應付急速增長的貸款需求。
  6. The main characters of the design are summarized as follow : 1. each mmdb module is mapped with a data buffer which is used to track the unsynchronized record. when system uploads the data to the mmdb, our system will adopt the round - robin fashion to distribute the data to each module, thus could effectively reduce the load of the foreground system

    針對上述難點採用以下方式對系統進行了優化，有效的保證系統的實時性和可靠性: 1 .數據上載時採用失步緩沖區和內存庫一一對應的關系，對每個內存數據庫數據定時循環上載，減少對單個數據庫的負荷，有效的控制上載流量和速度，防止在上載數據過程中系統負荷過大影響業務操作。
  7. As a general rule, an adequately sized globe valve ( i. e. with pipe velocity between 15 to 25 ft / sec for water and 200 to 300 ft / sec for steam ) should not be throttled down below 35 % of its maximum full open cv capacity ( approximately 20 % of full stroke )

    一般而言，通徑足夠大的截止閥（例如管道內水流速度在15至25英尺/秒之間，蒸汽流速在200至300英尺/秒之間） ，節流后的流量不應該小於完全開啟狀態流量（流量系數大約為全沖程的20 % ）的35 %以下。
