I ka nui o ka wā kamaliʻi ma hope o ka makahiki 80 a ma hope o ka makahiki 90, he mea nui nā baluna hydrogen.I kēia manawa, ʻaʻole i kaupalena ʻia ke ʻano o nā baluna hydrogen i nā hiʻohiʻona kiʻi.Nui nō hoʻi nā baluna ʻulaʻula ʻulaʻula i hoʻonani ʻia me nā kukui, i makemake nui ʻia e nā ʻōpio he nui.
Eia naʻe, pilikia loa nā baluna hydrogen.Aia ka hydrogen i ka lewa a hamo aku me nā mea ʻē aʻe e hoʻohua i ka uila paʻa, a i ʻole e hālāwai me nā lapalapa ākea, ua maʻalahi ke pahū.I ka makahiki 2017, ua hōʻike ʻia he ʻehā mau ʻōpio ma Nanjing i kūʻai aku i ʻeono mau baluna ʻulaʻula ma ka pūnaewele, akā ʻo kekahi o lākou i paʻipaʻi ʻia i nā ʻūhā ma nā baluna i ka wā e puhi ana.ʻO ka hopena, ua pahū nā baluna ʻeono ma hope o kekahi, a ua pau nā kānaka i ke ahi nui.Ua loaʻa i ʻelua o lākou nā maʻi maʻi ma ko lākou mau lima, a ua hiki ke kuni maka i ka Papa II.
No ka palekana, ua ʻike ʻia kekahi ʻano "baluna helium" ma ka mākeke.ʻAʻole maʻalahi ka pahū a me ke ahi, a ʻoi aku ka palekana ma mua o ka baluna hydrogen.
No ke aha e hoʻohana ai i nā baluna helium
E hoʻomaopopo mua kākou i ke kumu e hiki ai i ka helium ke lele i nā baluna.
ʻO nā kinoea hoʻopiha maʻamau i nā baluna he hydrogen a he helium.No ka mea, ʻoi aku ka haʻahaʻa o kēia mau kinoea ʻelua ma mua o ka ea, ʻo ka nui o ka hydrogen he 0.09kg/m3, ʻo ka haʻahaʻa o ka helium he 0.18kg/m3, a ʻo ka nui o ka ea he 1.29kg/m3.No laila, i ka wā e hui ai nā ʻekolu, e hoʻokiʻekiʻe mālie ka ea ʻoi aku iā lākou i luna, a e lana mau ka baluna i luna ma muli o ka buoyancy.
ʻOiaʻiʻo, nui nā kinoea me ka haʻahaʻa haʻahaʻa ma mua o ka ea, e like me ka ammonia me ka nui o 0.77kg / m3.Eia nō naʻe, no ka hoʻonāukiuki nui ʻana o ka ʻala o ka amonia, hiki ke hoʻopili maʻalahi ʻia ma ka mucosa ʻili a me ka conjunctiva, e hoʻoulu ai i ka huhū a me ka mumū.No nā kumu palekana, ʻaʻole hiki ke hoʻopiha ʻia ka ammonia i loko o ka baluna.
ʻAʻole haʻahaʻa ka Helium i ka haʻahaʻa, akā paʻakikī hoʻi e puhi, no laila ua lilo ia i mea pani maikaʻi loa no ka hydrogen.
Hiki ke hoʻohana ʻia ka Helium ʻaʻole wale, akā ākea pū kekahi.
Hoʻohana nui ʻia ka Helium
Inā manaʻo ʻoe hiki ke hoʻohana wale ʻia ka helium e hoʻopiha i nā baluna, ua hewa ʻoe.ʻOiaʻiʻo, ʻoi aku ka nui o ka helium ma mua o kēia mau hopena iā mākou.Akā naʻe, ʻaʻole pono ka helium.He mea koʻikoʻi loa ia ma ka ʻoihana koa, ka noiʻi ʻepekema, ka ʻoihana a me nā ʻoihana ʻē aʻe he nui.
I ka hoohehee ana a me ka wiliwili metala, hiki i ka helium ke hookaawale i ka oxygen, no laila hiki ke hoohana ia e hana i kahi kaiapuni pale e pale aku ai i ka hopena kemika ma waena o nā mea a me ka oxygen.
Eia kekahi, he haʻahaʻa haʻahaʻa loa ko ka helium a hiki ke hoʻohana ʻia e like me ka refrigerant.Hoʻohana nui ʻia ka helium wai ma ke ʻano he mea hoʻomaha a me ka mea hoʻomaʻemaʻe no nā reactors atomic.I ka manawa like, hiki ke hoʻohana ʻia e like me ka booster a me ka booster o ka wahie rocket wai.Ma ka awelika, hoʻohana ʻo NASA i nā haneli miliona cubic feet o ka helium i kēlā me kēia makahiki i ka noiʻi ʻepekema.
Hoʻohana ʻia ka Helium ma nā wahi he nui o ko mākou ola.No ka laʻana, e hoʻopiha ʻia nā mokulele i ka helium.ʻOiai ʻoi aku ka kiʻekiʻe o ka helium ma mua o ka hydrogen, ʻo ka hiki ke hāpai ʻia o nā baluna piha helium a me nā mokulele he 93% o nā baluna hydrogen a me nā mokulele me ka leo like, a ʻaʻohe ʻokoʻa.
Eia kekahi, ʻaʻole hiki i nā mokulele a me nā baluna piha helium ke puhi i ke ahi a pahū, a ʻoi aku ka palekana ma mua o ka hydrogen.I ka makahiki 1915, ua hoʻohana mua ʻo Kelemania i ka helium e like me ke kinoea e hoʻopiha ai i nā mokulele.Inā nele ka helium, ʻaʻole hiki ke piʻi i luna i ka lewa nā baluna kani a me nā moku ākea i hoʻohana ʻia no ke ana ʻana i ka wā.
Eia kekahi, hiki ke hoʻohana ʻia ka helium i nā lole luʻu, nā kukui neon, nā mea hōʻailona kiʻekiʻe a me nā mea ʻē aʻe, a me ka hapa nui o nā ʻeke pahu pahu i kūʻai ʻia ma ka mākeke, aia pū kekahi he helium liʻiliʻi.
