Actually the country should develop integrated circuit, take national security seriously, be not the CPU nucleus that must develop oneself, although develop the CPU kernel that gave out oneself to want industrialization, do do greatly strong, also often can encounter abroad already had the patent encircle and suppress of CPU nucleus and CPU technology, be in early had used patent to build the enclosing wall of much nucleus CPU with the Intel, IBM company that give priority to before New Year more, development CPU breaks through this kind of encircle and suppress very hard, the CPU nucleus that is not oneself won't violate the family's patent, before long a company of domestic is opposite before monicker says development went as compatible as ARM IP nucleus, the accredit that the sale outside wanting to be opposite still wants to acquire ARM company also is this path manage.

其实国家要发展集成电路，重视国家安全，并非一定要研制自己的CPU核，即使研制开发出了自己的CPU内核要产业化、做大做强，往往也会遭遇国外已有CPU核及CPU技术的专利围剿，早在多年前以Intel、IBM等为主的公司已经用专利将多核CPU的围墙建了起来，发展CPU很难突破这种围剿，并不是自己的CPU核便不会侵犯人家的专利，前不久国内一家公司对外号称开发出了与ARM兼容的IP核，要想对外销售依然要获得ARM公司的授权也是这个道理。

Infrared remote control launcher because electric circuit simple, worktables reliable, function complete, the ease of operation, tenant jamming is strong, cannot radiate and so on the merit, in aspect and so on domestic electric appliances, intelligent instrument measuring appliance, industry control, computer network and correspondence domain, medical equipment has the extremely widespread application.

A comparison is made of advantages and defects among protective measures,including adopting advanced imported regulator ,installing fast isolating valve in front of regulator ,using two-circuit regulator plus fast isolating valve,installing excessive underpressure automatic isolating valve in front of domestic gas meter etc.

分析了中压燃气直接进入用户燃气表的危害，比较了采用先进的进口调压器、在调压器前安装快速切断阀、采用双回路调压器加快速切断阀、在家用燃气表前装设超欠压自动切断阀等预防措施的优缺点，提出了其适用场所。

However, according to the operation of"GZB-SNQ and TSQ-GBJ HVDC project", reliability of Circuit Protection Device of domestic and international HVDC lines is not high, within easily disoperation and other issues. So how to improve reliability of HVDC transmission lines is urgently needed to solve in our country's development of HVDC.

然而根据葛上直流输电工程和天广直流输电工程的运行情况来看，目前国内外投运的直流线路继电保护装置普遍存在着可靠性不高，易误动等问题，因此如何提高直流输电线路保护的可靠性是我国发展直流输电亟待解决的问题。
