硫化氢

As the raise of ammonia-N concentration, survival rate and daily growth of unexuviated larvae decreased gradually, while the metamorphosis rate and daily growth of exuviated larvae increased gradually firstly and then decreased. As the raise of sulfureted hydrogen concentration, all the parameters measured decreased gradually.

在本试验浓度范围内，随着氨氮浓度的升高，三疣梭子蟹各期幼体存活率和未变态个体的日生长率都逐渐降低，变态率和变态个体的日生长率则先逐渐升高，达到一个峰值后又逐渐降低；随着硫化氢浓度的升高，三疣梭子蟹各期幼体存活率和日生长率A均呈现逐渐降低趋势，变态率和日生长率B也逐渐减小。

The corresponding measures, such as installing pressure control valve and flow control valve to stabilize feed gas and ensuring in-line meter to operate normally to automatically and quickly feed air and hydrogen, have been taken to increase sulphur recovery from 92% to 99% and decrease S02 c...

鉴此，增设酸性气进料压力控制阀和流量控制阀，稳定装置硫化氢进料；确保在线分析仪表工作状态完好，保证装置配风和配氢操作自动、灵敏；优化控制条件，实现总硫回收率由原来的92％提高到99％，排放尾气二氧化硫含量由2 800 mg/m3降到343 mg/m3。

Hydrogen induced cracking problem of pipelines exists extensively in natural gas transportation engineering, especially for ...

The pathogen of gas gangrene mainly exist and live in local place, and seldom enter blood system to cause blood poisoning, but than can form lots of toxins, this toxins can harm blood system, kidney system, and also the tissue can putrescence and the wound will enlarge step by step, all tissue putrescence and toxin can make these bacteria easier to live and reproduce, all these situation if not being control in time will lead a serious situation that multiple organs dysfunction and then died

气性坏疽的病原菌主要在伤口内生长繁殖很少侵入血液循环引起败血症。产气夹膜杆菌产生α毒素、胶原酶透明质酸酶、溶纤维酶和脱氧核糖核酸酶等，红细胞破坏引起溶血血红蛋白尿、尿少、肾组织坏死水肿、液化，肌肉大片坏死使病变迅速扩散、恶化。糖类分解产生大量气体使组织膨胀；蛋白质的分解和明胶的液化，产生硫化氢，使伤口发生恶臭由于局部缺血，血浆渗出，及各种毒素的作用伤口内的组织和肌肉，进一步坏死和腐化，更利于细菌的繁殖使病变更为恶化。

On the basis of volatile odor of storage fish, four-gas sensor arrays (TGS822 for ethanol; TGS825 for H2S; TGGS826 for NH3 and aime, TGS832 for halocarbon) were selected as the nose of electronic nose system, the electronic nose measurement system was constructed based on LabVIEW, then silver carp meat during storage was investigated by using this system. The results indicate that the response of electronic nose is correlated with freshness loss of fish.

该文分析了鱼体死亡后产生的特征挥发性气体，确定了TGS822乙醇类及有机溶剂型传感器、TGS825硫化氢型传感器、TGS826氨气及胺类型传感器以及TGS832 卤烃型气体传感器等4类传感器作为淡水鱼电子鼻的传感器阵列，并采用虚拟仪器平台开发了电子鼻测量系统，用该测量系统对不同新鲜度的鲢鱼鱼肉进行了气味检测。
