您要查找的是不是：
- TLV（Type-Length-Value）TLV(Type-Length-Value)
- Qs/Qt于TLV時(shí)兩藥間無(wú)差異(P>005),但OLV時(shí)安氟醚較為明顯(P<001)。though having no difference during TLV between two inhaled drugs( P <0 05),Qs/Qt was found higher when ENF was received than SEVO did at two concentration during OLV( P <0 01).
- OLV 時(shí)血氣值也發(fā)生了改變,即 PaO_2 較TLV降低 50%,而 PaCO_2 在 OLV-等壓時(shí)升高,通過(guò)調整V_A 可予糾正。and 4) At the same time the related blood-gas analysis were abnormal. PaO2 was 50%25 lower during OLV than during TLV. PaCO2 was higher during OLV-equal Paw than during TLV (P<0. 01).
- 最大允許濃度（TLV）所指的是在所定的濃度環(huán)境下，操作人員可以保持每天8小時(shí)，每周48小時(shí)的正常工作，而不會(huì )對人體造成損害。Threshold limit value (TLV) means under the condition of a specified concentration, it is not harmful to human beings to keep handling the product for 8 hours a day or 48 hours a week.
- 美國政府工業(yè)衛生學(xué)者會(huì )議把NF3的TLV-TWA (10 ppm或29 mg/m3[ACGIH,1997])設定為前面在“毒物學(xué)性質(zhì)”下引用的19周研究的測試水平的十分之一。The TLV-TWA (10 ppm or 29 mg/m3[ACGIH,1997]) for NF3 was set by the American Conference of Governmental Industrial Hygienists at one-tenth the test level of the previously cited 19-week study under Toxicological Properties.
- 正如美國政府工業(yè)衛生學(xué)者會(huì )議和職業(yè)安全和健康管理局所列出的，對于二氧化碳的TLV-TWA值是百萬(wàn)分之5000或0.5%。對于二氧化碳，CAS #是124-38-9。The TLV-TWA for CO2, as listed by American Conference of Governmental Industrial Hygienists and by the Occupational Safety and Health Administration, is 5000 parts per million, or 0.5%25.The CAS %23 for CO2 is 124-38-9.
- 閾值極限-時(shí)間權重平均值(TLV-TWA)是對于正常的8小時(shí)工作日和40小時(shí)工作周的時(shí)間權重平均值，在該值下，大多數工人日復一日的重復暴露在其中而不會(huì )受到有害影響。Threshold Limit Value-Time Weighted Average (TLV-TWA) is the time-weighted average concentration for a normal 8-hour workday and 40-hour workweek, to which nearly all workers may be repeatedly exposed, day after day, without adverse effect.
- PFC組TLV 5min時(shí)PaO_2均較基礎狀態(tài)(TLV前)明顯降低,15、30、45min各時(shí)間點(diǎn)PaO_2較5min明顯增高,15、30、45min PaO_2間無(wú)顯著(zhù)差異,TLV后PaCO_2進(jìn)行性升高、pH進(jìn)行性下降。In PFC group, PaO2 of 5 minutes was significantly lower compared with 0 minutes, PaO2 of 15, 30 and 45 minutes was significantly higher compared with 5 minutes, there were no different of PaO2 between 15,30 and 45 minutes. PaCO2 was gradually increased and pH gradually decreased after TLV in PFC group.
- 該策略通過(guò)對網(wǎng)絡(luò )資源屬性和業(yè)務(wù)流屬性的綜合考慮,依據對特定業(yè)務(wù)流進(jìn)行裁決的判別函數,將適于遷移的TLV結構業(yè)務(wù)流進(jìn)行合理地及時(shí)遷移,從而達到提高網(wǎng)絡(luò )資源利用率的目的。Considering the attributes of network resource and the attributes of traffic flows synthetically,the strategy can transfer the suited traffic flows of TLV structure in time and enhance the utilization rate of network resources according to the estimation function for certain traffic flows.
- 在麻醉后雙肺通氣 (two -lungventilation ,TLV) 15min(t1) ,OLV 30min(t2 ) ,OLV 6 0min(t3) ,TLV 30min(t4 )時(shí)間點(diǎn)抽取動(dòng)脈血和右心房血 ,行血氣分析檢查 ,并計算肺內分流量 (Qs/Qt)。The arterial and right atrium blood were taken for blood gas analysis at the following time: TLV 15 min( t 1), OLV 30 min ( t 2), OLV 60 min( t 3), TLV 30 min( t 4), and the Qs/Qt was calculated.
