PbWO4 and CeF3 which are newly developed inorganic scinti1latr in our country have been studied. Photo-electricity detector systemes which have high γ sensitivity and relative insensitive to neutron and fast time response were assembled by using CeF3 and photomultiplier tube. The ratio of signal-to-noise for γ ray detection can be up to more than 10 times in close distance n,γ commix pulse radiation field by using this detector system.

五、风管采用镀锌板制作，具体长度按厂房尺寸设计，标配长度单个最长不超过6米，超过部分另计；喷房室外独立送风系统*2套，UV室室外独立送风系统*1套，静电除尘室室外独立送风系统*2套，独立室外送风系统均包含三级过滤。

In the present review, we focus on some of the recent advances and some key developmental events revealed in the fertilization process, including the role of the egg apparatus in guiding pollen tube orientation, sperm cell movement to their targeting cells, interaction between gametes, egg cell activation, and onset of embryogenesis and endosperm development.

本文着重讨论受精作用的若干重要发育事件，包括受精前卵器细胞对花粉管向胚珠定向生长的近距离引导信号，精子的靶向运动，精、卵细胞相互作用和配子融合后卵细胞的激活与中央细胞发育的启动等。

Two 0.5-ml volumes of an isobutanol internal standard (10 mg/ml water; pipette 12.4 ml of isobutanol and dilute to 1 liter with water) are pipetted into two different 2-dram (7.4-ml) shell vials, one market "known."and the other "unknown."

将两份0.5毫升的异丁醇内标物(浓度为10mg/ml水，其配制法为：用吸量管吸取12.4ml 异丁醇用水稀释至1L )，用吸量管分别吸入两个不同的2-打兰(7.4毫升)的壳型小瓶中，一个标为&已知&，另一个标为&未知&。

Through test and analysis, the influence of putting auxiliary air of the double inlet and double outlet coal pulverizer into operation upon ecomomic behavior of the boiler for 300 MW unit in one power plant has been obtained.

摘要通过试验分析了某电厂300MW机组锅炉所配双进双出钢球磨煤机辅助风投运对锅炉排烟温度的影响，结果表明，锅炉运行期间只要磨煤机一次风管不堵管，就无需投入磨煤机辅助风，辅助风仅在启动前和停磨煤机后吹扫管道时投入即可。

To this end, the use of MCS-51 series AT89C51 single-chip device designed as the central traffic light control circuit, with a total of cathode seventh time the digital display module, the traffic light display module, transfer module, crystal oscillator circuit, reset circuit and control circuit 8051 in accordance with the actual traffic flow through the port P3 chip set red, green and double-time to kindle a digital countdown display,The turn of the three colors of lights and emergency lighting in case of interruption of processing.
