Research and development companies that have their own intellectual property rights dry ice cleaning technology to fill gaps in domestic , and the relevance of its innovative small and mid - sized enterprise access to the national ministry of science and technology innovation fund project funding 公司研究開發具有自主知識產權的干冰清洗技術,填補國內空白,以其創新性和實用性獲得國家科技部科技型中小企業技術創新基金的立項資助。

Glow discharge appears when applied voltage further increases . with air gap increases , the mean discharge magnitude reduces . there is not an obvious effect of water conductivity on the mean discharge magnitude at dry ice , however , the mean discharge magnitude increases when water conductivity increases 干冰時覆冰水電導率對平均放電量的影響不大;濕冰情況下,覆冰水電導率越大平均放電量越大,其平均放電量明顯高于干冰。

Development companies manufacture dry ice cleaning machines and dry ice machines have similar products advanced international level , the fine performance , the relative price of imports significantly reduced , and was widely praised by customers great 公司開發的干冰清洗機和干冰制造機具備同類產品國際先進水平,性能優良,價格相對進口產品大大降低,獲得客戶的極大認可和廣泛贊譽。

Production of dry ice equipment and production company dry ice rice , dry ice - cream brick products supply dry ice cleaning and refrigeration industry to expand the application areas of co2 and achieve “ reject the use of “ environmental guidelines no 公司生產干冰設備的同時生產干冰米、干冰磚等產品供應干冰清洗和冷凍行業,為擴展co2的應用領域,實現“廢品利用“的環保方針不遺余力。

The activation energy of the tpl peak is calculated being about 1 . 5 ev for four heat treated samples ( furnace cooling , air cooling , dry ice quenching , liquid nitrogen quenching ) , and it is near the self diffuse activation energy of aluminum 1 . 45ev 爐冷、空冷、干冰冷和液氮冷四種熱處理制度根據幾,峰峰溫數據計算的激活能的結果約為1 ? sev ,接近于鋁的自擴散激活能1 . 45ev 。

The news of the mystery woman on mars came just days after a team of french scientists claimed to have discovered proof that mars has high dense clouds of dry ice , which scud across its orange sky , indian newspaper hindustan times reported 據《印度斯坦時報》報道,在火星“神秘女郎”消息公布幾天前,法國一個科學家小組稱他們發現了火星橘紅色上空存在濃密干冰云的證據。

Carbon dioxide is often used for carbonated beverage , soda water , foodstuff , welding , plant protection , breeding , freezing , aquatic products , manufacture of the dry ice , fire extinguishing as the mixed gas used in surgery 二氧化碳日常常見用于碳酸飲料、汽水、食品、焊接、植物保護、養殖、冷凍、水產、制造干冰、消防滅火,醫療手術中用的混合氣。

During their brief lifetimes , the dry ice shards collide and spin a multi - armed vortex of white mist . they propel themselves around the tank leaving trailing wisps of water vapour similar in appearance to the tail of a comet 有些乾冰塊噴出的氣體所產生的反作用力,足以推著乾冰前進,使后面形成一條條水氣的流跡,好像彗星的尾巴。

The longer the air gap is , the higher the inception voltage ; the inception voltage is lower with 2kv at wet ice than dry ice . while , there is not a distinct effect of water conductivity on the initiative voltage 間隙越長,起暈電壓越高;濕冰情況下間隙的起暈電壓比干冰約低2kv ;而覆冰水電導率對起暈電壓沒有明顯的影響。

In “ icy bodies “ you slide a small piece of dry ice into a basin of tepid water . striking the water , the dry ice instantly begins to vaporize from its solid state into a gas , a process known as sublimation 在冰體景觀中,一小片乾冰滑進一盆微溫的水中,立即從固態氣化成氣體,這一過程稱為升華。

Realizing we ' d need dry ice , for some special effects , the director contacted the only distributor in town that delivered , explained our need and ordered a five - pound block 此刻我們突然發覺需要一些干冰,為了制造一些特殊效果,導演馬上和城里唯一的供貨商聯系運送事宜,解釋了我們的需求和需要5磅冰塊。

As it vaporizes , tiny gas jets spin and tumble the ice shards across the surface of the water . during their brief lifetimes , the dry ice shards collide and spin a multi - armed vortex of white mist 乾冰氣化時產生的小噴流帶動乾冰碎片在水面不斷旋轉翻滾,互相碰撞,產生一團團有多個分支的白霧旋渦。

When master appeared in the video , i was totally stunned : she was wearing a long white gown and sheer white veil , and disciples were using dry ice to create a smoke effect on stage 師父穿著一襲白色長袍,并戴著白色面紗,由于同修利用乾冰制造舞臺上的煙霧效果,因此師父站在煙霧繚繞的舞臺上。

As of 1 may 2000 , all refrigerated packages shipped via ups air services that contain five pounds of dry ice will require additional hazardous material shipping papers 自2000年5月1日起,所有通過ups空運服務運輸的冷凍包裹如果包含五磅重的干冰,就將需要額外的危險品運輸文件。

Content of the project : utilize co2 resource , to set up production lines of methyl carbonate , granular dry ice powder , salicylic acid , sodium carbonate and ethylene urea etc 項目內容:利用二氧化碳資源,新建碳酸二甲酯、顆粒干冰粉、水楊酸、輕質氧化鮮、碳酸鈉、乙撐脲生產線。

As of 1 may 2000 , all refrigerated packages shipped via ups air services that contain five pounds of dry ice will require additional hazardous material shipping papers 自2000年5月1日,所有經ups air service托運的冷凍包裹,只要含有五磅乾冰,便需要附加危險物品托運報告。

Examples of such applications are ; dry ice production , beer , carbonation , and its direct use in as raw material for synthesis reactions in chemical plants 典型用途:主要用于回收啤酒廠和酒精廠發酵過程中產生的二氧化碳,將其純化液化罐裝和制干冰,以供使用。

1 enject ethanol or acetone about 25mm to the dew - point meter container , then put in dry ice to refrigerate and keep the centigrade up to or lower than - 40 2將試樣水平放置,在上面涂一層乙醇或丙酮。使露點儀與該表面緊密接觸,停留時間按表4的規定。
