  special conditions
A new method of isolation of mitochondria in special conditions by differential centrifugation at 1700, 10,000, and 17,000g resulted in three fractions of mitochondria.
      
The general and special conditions of compatibility are formulated.
      
It is inferred that this effect, which does not require any special conditions in order to appear, can serve as an indication of the presence of standing waves in one of the electrodes.
      
However, this method requires that the potential U(a,φ) satisfy special conditions in the space (a,φ).
      
It is shown that the resulting composite material is characterized by a negative refractive index only under certain special conditions: in the absence of a strong quasistatic coupling between the two subsystems.

In view of the situation that in our 30000t/a coaxial type catalytic cracking unit the regenerator has its flue gas vent to atmosphere making loud noise and polluting the envi-ronment,we have developed a miniature perforated board─acoustic reactance combination type of muffler.It has properties of low resistance loss and resistance tO high temperature,oil,steam and corrosion.It is of light weight,small volume and produces good result of eliminating noise.In addition,it can be used to eliminate gas current noise...

In view of the situation that in our 30000t/a coaxial type catalytic cracking unit the regenerator has its flue gas vent to atmosphere making loud noise and polluting the envi-ronment,we have developed a miniature perforated board─acoustic reactance combination type of muffler.It has properties of low resistance loss and resistance tO high temperature,oil,steam and corrosion.It is of light weight,small volume and produces good result of eliminating noise.In addition,it can be used to eliminate gas current noise within wider frequency range and ap-plied under special conditions such as ephemeral flame and high speed gas current. Since Jan-uary,1988 the muffler has been used in the catalytic cracking unit for four years demonstrating its voluminous muffling,stability,reliability and durability with a remarkable result of muf-fling in the unit and plant.

微穿孔板─抗性组合式消声器是针对本厂3万t/a同轴式催化裂化装置再生器烟气排空噪声大,污染环境而进行研制的,具有阻损小、耐高温、耐油污、耐蒸汽和耐腐蚀等性能,而且消声效果好、重量轻、体积小,能在较宽的频率范围内消除气流噪声,还能在短暂火焰和高速气流的特殊条件下使用。该消声器自1988年1月在催化裂化装置上使用4年来,消声量大、消声器性能稳定可靠,经久耐用,对消除装置噪声及厂界噪声效果显著。

The occurrences of the spontaneous ignition of the comprehensive mining coal face at the spontaneous combustion coal-seam under a special condition from the 1301 face in Gengcun coal mine has been analysed. In order to prevent the spontaneous ignition at the working face, which caused by the air leakage in the goaf, the comprehensive fire-preventing measures are adopted for balanced-pressure ventilation, low-volume air supply, and the speed_up tunnelling at coal face. The testing performances at worksite shows...

The occurrences of the spontaneous ignition of the comprehensive mining coal face at the spontaneous combustion coal-seam under a special condition from the 1301 face in Gengcun coal mine has been analysed. In order to prevent the spontaneous ignition at the working face, which caused by the air leakage in the goaf, the comprehensive fire-preventing measures are adopted for balanced-pressure ventilation, low-volume air supply, and the speed_up tunnelling at coal face. The testing performances at worksite shows that the measures are both practical and effective for preventing the spontaneous ignition. Therefore, the safety-production in coal mines have been insured.

分析了耿村矿1301工作面易自燃煤层特殊条件下综放开采工作面自然发火的危险性;探讨了因采空区漏风而引起的工作面自然发火的防治措施.经现场实施研究表明,均压通风、低风量供风、加快工作面推进速度的综合防火技术,成功地防止了自然发火,保证了综放开采工作面的安全生产.

According to the special conditions of new south airshaft in Tonglushan Mine, a method of grout sealing water outlet in crosscut by throwing grout mixture at shaft collar has been developed to control water flooding in the shaft. The authors calculate and analyze the thickness of subsealing layer, the operation programe of subsealing grout and the quantity of grout. The application of this grout subsealing method has obtained a good result in the project.

根据铜绿山矿新南风井特殊条件,研究了井口抛料注浆封堵石门出水点的治理方法,并对封水层厚度、封底注浆工作程序及注浆量进行了计算与分析,在工程中取得了很好的应用效果
