中文版： 西亞磁翻板液位計(jì)產(chǎn)品必須自力更生：我國的科研發(fā)展能否建立在主要依靠國外儀器的基礎(chǔ)上，短期看似能滿足國內(nèi)科研的需求，但長期看國外的磁翻板液位計(jì)決不是支撐國內(nèi)科研跨越發(fā)展的堅(jiān)強(qiáng)支柱。我國科研整體不差錢，在此情況下，考慮到國內(nèi)許多磁翻板液位計(jì)雖價(jià)廉但質(zhì)不高，從國外采購就成為優(yōu)先考慮和實(shí)施的，中國的科研活動(dòng)在一定程度上支持了國外磁翻板液位計(jì)廠商的經(jīng)營業(yè)績，如果能統(tǒng)計(jì)一下每年采購的國外電容式壓力變送器占當(dāng)年采購儀器的比例，就能清楚看到磁翻板液位計(jì)方面的差距。進(jìn)口的磁翻板液位計(jì)生產(chǎn)國是美國、日本、歐盟和俄羅斯，本身一些高精密磁翻板液位計(jì)對中國就是限制進(jìn)口的；前沿科研更需要向電容式壓力變送器廠商定制的非標(biāo)儀器，靠采購成熟的商品開展研究，部分研究只能是跟著國外的技術(shù)在跑；形勢復(fù)雜多變，現(xiàn)在能采購來，不見得將來也能采購來。 從質(zhì)量上看國產(chǎn)磁翻板液位計(jì)僅從外觀上就與國外有一定差距。在實(shí)際的科研活動(dòng)中，以核物理研究所需磁翻板液位計(jì)為例，國外產(chǎn)品占據(jù)壓倒性的優(yōu)勢，國內(nèi)生產(chǎn)商規(guī)模不斷萎縮，市場分額越來越小，甚至直接倒閉。優(yōu)先考慮國外磁翻板液位計(jì)已成國內(nèi)技術(shù)開發(fā)人員的一種習(xí)慣。不大力發(fā)展磁翻板液位計(jì)必將成為科研發(fā)展的軟肋?？蒲袕?qiáng)國必是磁翻板液位計(jì)強(qiáng)國，美國、日本、德國都是如此，按理推論，不是磁翻板液位計(jì)強(qiáng)國也就很難成為科研強(qiáng)國，即使你的科研規(guī)模很大，但實(shí)際上只是構(gòu)建在沙灘上的城堡。磁翻板液位計(jì)產(chǎn)業(yè)對于科研的重要性是不言而喻的，可以說科研技術(shù)的發(fā)展在一定程度上就是磁翻板液位計(jì)所推動(dòng)的，然而磁翻板液位計(jì)卻是制約我國科研發(fā)展的短板，具體表現(xiàn)在：國外磁翻板液位計(jì)大舉進(jìn)入，國內(nèi)儀器儀表舉步維艱。英文版：West Asia magnetic level indicator products must rely through one's own efforts: China's scientific development can be built on the basis of mainly rely on foreign instruments, short-term seems to meet the domestic needs of scientific research, but the long term foreign magnetic level gauge is not supporting the domestic scientific research across the development of a strong pillar. Our research is not bad money, in this case, taking into account the domestic many magnetic level gauge is cheap but the quality is not high, has become the purchase from abroad is preferred and the implementation of China's scientific research activities, support the foreign magnetic level meter manufacturers operating performance in the certain degree, if the foreign capacitor pressure transmitter can count every year procurement accounted for the proportion of purchasing equipment, can clearly see the magnetic level meter gap. Imported magnetic level gauge in the United States, Japan, is the production of the European Union and Russia, itself some high precision magnetic level indicator of China's import restrictions; frontier research needs to non-standard equipment capacitance pressure transmitter manufacturers custom, by purchasing mature product development research, part of the research can only be followed foreign technology in running; the complex and volatile international situation, can buy now, not necessarily will be able to purchase.Domestic magnetic level gauge just from the appearance and overseas have a certain gap in quality. In the scientific research activities, the Institute of nuclear physics required magnetic level meter for example, foreign products occupy the overwhelming superiority, the domestic manufacturer shrinking, the market share is getting smaller and smaller, and even direct the closure. Priority to foreign magnetic level gauge has become a habit of staff development in china. Turning plate level gauge will become the scientific research development problem do not develop magnetic. Research of power must be magnetic level gauge power, the United States, Japan, Germany is so, by inference, not magnetic level gauge power is difficult to become a scientific power, even if your research is large in scale, but is actually built on sand castle. Magnetic level meter industry is self-evident to the importance of scientific research, can be said that the development of science and technology in a certain extent is magnetic level indicator is the short board, but magnetic level indicator is restricting China's research and development, specifically manifested in: foreign magnetic level gauge is entered in a large-scale, China Instrument difficult.
