  4. Sometimes we want to stop a gene from expressing its product, because the product is toxic ( such as the mutation that causes huntington ' s disease ), but even then we can probably achieve the desired effect just by putting in a gene, because we can use the amazing phenomenon of rna interference to cause the gene ' s transcript to be destroyed before it is translated

    有時，我們要停止一種基因表達它的產物，因為這種產物有毒性（例如，引起亨廷頓氏舞蹈病的突變） ，但即使在這種情況下，我們也有可能僅僅放進一個基因，來達到想要達到的效果，因為我們可以利用rna干涉的這種令人驚訝現象、在該基因的轉錄物在被翻譯之前就毀壞它。

  11. As to the video signal, alarm signal, control signal, are all weak electricity signal, exceedingly easily be subjected to the jam, in case the power supply system does not steady, wave propag ation is greatly, the harmonic content of power source overtops, the veins wave factors are great unduly, and even power source equipment breakdown, outputting abnormal, will be about to affect the video signal image effect, and dependability cuts downs to the security and alarming system. we adopt fast fu lye ' s mutation rule - fft alternatives, by the way of carrying fft alternatives to the local junction circuit, regulated power supply, ups ' s power source, and switch power source, thereby diagnose every degree harmonious wave content of power souse, and abnormal coefficient, compared to the normal working situation. thereby diagnose out the working condition of the regulated power supply, ups ' s power source, and switch power source

    如果有供電系統不穩定、波動大，電源的諧波含量過高，紋波系數過大，乃至電源設備損壞、輸出異常等情況出現，將會嚴重影響視頻信號的圖像效果，大大降低防盜系統的穩定性和可靠性，我們採用快速傅利葉變換原理，即fft變換，通過對市電、穩壓電源、 ups電源、開關電源等的電壓信號進行fft變換，從而得出信號中各次諧波的含量及信號畸變系數，並將其與正常工況下的參數進行對比，從而進一步診斷出穩壓電源、 ups電源、開關電源等設備的運行狀況；組成監控系統的設備長期處于工作狀態，往往由於設備散熱條件不好、設備老化故障等原因導致設備表面溫度過高，從而影響設備的正常運行，降低設備的使用壽命。
