片孔效應 的英文怎麼說
中文拼音 [piānkǒngxiàoyīng]
片孔效應
英文
sprocket hole effect-
The comparison of stomatal parameters in leaf cuticles between two fossil angiosperms from the pliocene in west yunnan and their nearest living equivalent species indicates a little higher atmospheric co2 level at that time than the present, while carbon isotopic composition of fossil cuticles demonstrates much higher carbon isotopic discrimination and slight lower water use efficiency, showing a warmer and wetter climate than today
摘要對滇西騰沖新近紀兩種被子植物葉片及其現存對應種的氣孔參數和碳同位素組成的綜合分析表明：當時的大氣co2濃度略高於現在水平；化石種的碳同位素分餾值高於現存對應種，但水分利用效率低於現存對應種；這證明當時的氣候條件比當前更為溫暖濕潤。Abstract : a new type of rotating packed bed （ rpb ） filled with holed disk packing, has high mass transference character by means of the centrifugal field it is used for simulating flue gas desulfurization and achieved of good effect the desulfurization efficiency of rpb by boot water is above 75 % accompanied with small gas resistance
文摘:一種利用離心力場強化傳質的新型旋轉填充床反應器以孔型碟片為填料用清水吸收模擬煙氣中的二氧化硫時的脫硫率達75 %以上，用於模擬煙氣脫硫也取得了很好的效果，而且氣阻也很低This model of valve overcomes such defects with the motor valve, piston - type electromagnetic valve as the post - wear defective closure due to the mechanical movement, the soft membrane full of elasticity, the balance hole can not close water because the foreign matters and mud sand accumulate and block it up etc., the highly effective use of the unique circuit greatly raises the reliability of the switch, extensively used for ic card watermeter, infrared induced sanitary utensils, etc
Fck - 118 ：進水口出水口為1寸25內螺紋該型閥克服了如電機閥活塞式電磁閥機械運動磨損后的關閉不良。軟性膜片富有彈性，平衡小孔不會因雜質與泥沙的淤積堵塞使其關不住水，獨特線圈磁路的高效利用大大提高了閥開關可靠性，廣泛用於ic卡水表紅外線感應潔具等自動控水系統。Some previous experiments have showed that cavities had more efficient gettering than p - diffusion, mechanical damage and ion implantation. most of studies about cavities gettering are concentrated on the peculiarity of cavities gettering metal impurities intentionally into silicon wafer from the viewpoint of basic study. this technique especially applied to low - contamination process, how ever, has not been carefully studied, which should be important to the semiconductor manufacturing
而過去的工作多集中在從基礎研究的角度研究氦微孔對有意摻入金屬雜質的矽片的吸除特性，對無意引入的低濃度金屬雜質的器件吸雜效果的研究卻非常少，這方面的研究是氦微孔技術走向實際應用的必經之路。分享友人
