This paper proposes a single channel detection receiver scheme for the HF adaptive three-array nulling antenna system and analyzes the feasibility of and the methods for its implementation.

文中对HF自适应三元阵列零位天线系统提出了一种单通道检测接收机方案，并分析了实现的可行性，给出了具体的实现方法，同时讨论了相关矩阵的算法。

Such as PVC, urea, the anhydride, caustic soda production plant, or external leakage demanding medium, such as HF, such as phosgene.

如PVC、尿素、本酐、烧碱生产装置中，或对外泄漏要求高介质，如HF，光气等。

As the sacrifice layer was obviated by HF solution, the bilayer will roll up spontaneously by strain release caused by lattice constant mismatch. Through this principle, we can fabricate self-rolled up microtubes.

同时在bilayer的下方成长一层牺牲层，当牺牲层被HF蚀刻去除的同时，bilayer会因为晶格常数不匹配而产生内部strain release的效果，而制作出自发卷曲的微米管。

2 The measurement of temperature of solid propellant plume by remote sensing FTIR The infrared radiance spectra was obtained by remote sensing FTIR. The temperatures of four plumes of propellants and a infrared reagent were calculated according to the gas vibration rotation band fine structure such as CO, HF, H2O and HC1 in plume of solid rocket propellant. The results have a agreement with the theoretical data.

2.2 FTIR遥测固体推进剂羽流温度本文利用遥感FTIR测试技术测得了固体火箭推进剂羽流的红外辐射亮度分布图，并根据谱图中CO、HF、HZO、HCI四种气体振转谱带精细结构计算了推进剂羽流温度及红外辐射药剂的燃烧温度，计算结果与理论预测值基本一致。

The titer of HF-WX antiserum and IgY is 1/1024 and 1/512 detected by miniprecipitation, respectively.

测得IgY和HF-WX抗血清的效价为1/512和1/1024。

Available good quality age dates and zircon Hf isotopic data suggest that the northern parts of the Gangdese experienced a zonal magmatic flareup with strong input of mantlederived materials at ~110 Ma.

已有高质量年龄数据和锆石Hf同位素指示冈底斯带中北部地区在大约110 Ma发生了带状岩浆大爆发并伴随着幔源物质显著增加。

In addition, 182^Hf is a longlived radionuclide of particular interest for nuclear engineering.

因此182^Hf是研究近1亿年来在地球附近可能发生的超新星事件的理想核素。

He does not think he has any influence on HF.
