Nezuro, Zhang wekurabhoritari akandinyunyuta zvakare kuti data rekuyedza sampuli raive risingawirirane nguva dzose. Ndakamubata pafudzi ndikati, “Hama, senyanzvi dzezvinhu, hatingotarise mapepa edata chete; tinofanira kusvibisa maoko edu tonzwisisa hunhu hwema micropowders aya machena akasanganiswa ealumina.” Izvi ndezvechokwadi; kungofanana nemubiki ane ruzivo anoziva tembiricha yakakodzera yekubika, isu vanoedza tinofanira "kushamwaridzana" nema "powders" aya machena anoita seakajairika kutanga.
Upfu hwe alumina hwakasanganiswa hunozivikanwa muindasitiri semhando yekristaroaruminiyamu oxide, ine kuomarara kweMohs kwe9, iri yechipiri kune dhaimani. Asi unenge wakanganisa kana ukaiona seimwe chinhu chakaoma. Mwedzi wapera, takagamuchira mapoka matatu esampuli kubva kuvagadziri vakasiyana. Dzese dzaitaridzika seupfu hwakachena sechando, asi pasi pemaelektron microscope, imwe neimwe yaive nehunhu hwayo—mamwe mativi aive nemicheto yakapinza semagirazi akapwanyika, nepo mamwe aive akatsetseka sejecha regungwa. Izvi zvinotungamira kudambudziko rekutanga: kuyedza kuomarara hakusi mutambo wenhamba uri nyore.
Tinowanzo shandisa microhardness tester, paunodzvanya indenter pasi wobva wabuda data. Asi pane zvimwe zvinhu: kana kumhanya kwekutakura kuri kukuru, brittle particles dzinogona kutsemuka kamwe kamwe; kana mutoro wacho wakareruka, hauzoyere kuoma kwechokwadi. Pane imwe nguva, ndakaedza sample imwe chete nemaune pamatanho maviri akasiyana, uye mhedzisiro yacho yakasiyana ne 0.8 Mohs hardness units. Zvakafanana nekudzvanya watermelon nemaoko ako; simba rakawandisa wobva watsemura, shoma uye haugone kuona kana yaibva. Saka ikozvino, tisati taedza, tinofanira "kugadzirisa" samples munzvimbo inodziya uye ine hunyoro kwemaawa makumi maviri nemana kuti dzienderane ne "temperament" yelab.
Kana iri bvunzo yekusapfeka zvakanaka, izvozvo zvinotova zvehunyanzvi. Nzira yakajairika ndeyekushandisa vhiri rerabha rakajairika kukwiza sampuli pasi pekumanikidzwa kwakatarwa uye kuyera kupera kwayo. Asi mukuita, ndakaona kuti kuwedzera kwega kwega kwe10% kwehunyoro hwezvakatipoteredza kunogona kukonzera kuchinja kweanopfuura 5% muhuwandu hwekupfeka. Gore rapfuura munguva yemvura, kuyedza kwakadzokororwa kashanu kwakaratidza data rakapararira zvakanyanya, uye takazoona kuti imhaka yekuti air conditioner yaisashanda zvakanaka. Mutariri wangu akataura chimwe chinhu chandichiri kurangarira: "Mamiriro ekunze ari kunze kwehwindo relabhoritari zvakare chikamu chezviyero zvekuyedza."
Chinonyanya kufadza ndechekukanganiswa kwechimiro chezvikamu. Zvikamu zvidiki zvakapinza zvinopera nekukurumidza kana zvaoma zvishoma—senge banga rakapinza asi risina kusimba rinocheka zviri nyore kana richicheka zvinhu zvakaoma. Zvikamu zvakatenderera, zvakagadzirwa nenzira chaiyo, zvinoratidza kugadzikana kunoshamisa kana zvaoma kwenguva refu. Izvi zvinondiyeuchidza nezvematombo ari parwizi pedyo neguta rangu; makore ekukura kwemafashamo akangoita kuti asimbiswe. Dzimwe nguva, kuomarara kwakanyanya hakuna kukodzera kuomarara kwakakodzera.
Pane imwe pfungwa iri nyore kufuratirwa mukuyedza: kugoverwa kwehukuru hwezvimedu. Munhu wese anotarisa paavhareji yehukuru hwezvimedu, asi chinonyanya kukanganisa kuramba kupfeka kazhinji i10% yezvimedu zvakapfava uye zvakakora. Zvakafanana ne "nhengo dzakakosha" dzechikwata; zvishoma uye hazvina zvazvinoita, zvakawanda uye zvinokanganisa mashandiro ese. Pane imwe nguva, mushure mekunge taongorora 5% yehupfu hwakapfava zvakanyanya, kuramba kupfeka kweboka rese rezvinhu kwakawedzera ne30%. Kuwanikwa uku kwakandiita kuti ndirumbidzwe naOld Wang kwehafu yemwedzi pamusangano wechikwata.
Zvino, mushure mebvunzo yega yega, ndava netsika yekuunganidza sampuro dzakaraswa. Upfu huchena hunobva mumapoka akasiyana hune kupenya kwakasiyana zvishoma pasi pechiedza; humwe hwakasviba, humwe hweyero. Nyanzvi dzine ruzivo dzinoti uku kuratidzwa kwemusiyano muchimiro chekristaro, uye misiyano iyi inowanzo cherechedzwa sechinyorwa chidiki chidiki papepa reruzivo rwechishandiso. Avo vanoshanda nemaoko avo vanoziva kuti zvinhu zvine hupenyu hwazvo; vanotaura nyaya dzavo kuburikidza nekuchinja kudiki.
Pakupedzisira, kuyedzaupfu hudiki hwecorundum chenaZvakafanana nekuziva munhu. Nhamba dziri paCV (kuoma, saizi yezvidimbu, kuchena) ingori ruzivo rwekutanga; kuti unyatsonzwisisa, unofanirwa kuona mashandiro ayo pasi pekumanikidzwa kwakasiyana (kuchinja kwemutoro), munzvimbo dzakasiyana (kuchinja kwetembiricha nehunyoro), uye mushure mekushandisa kwenguva refu (kuyedza kuneta). Muchina wekuyedza kupfeka unodhura mamiriyoni emadhora uri murabhoritari wakanyatsojeka, asi mhedzisiro yekupedzisira ichiri kubva pakubata nekutarisa—kufanana nenyanzvi yemakanika inogona kuona kuti chii chiri kunetsa nemuchina nekungoteerera ruzha rwawo.
Nguva inotevera paunoona "Kuoma 9, Kuramba Kupfeka Kwakanaka" pamushumo webvunzo, ungada kubvunza kuti: "Zvakanaka" izvi zvakawanikwa mumamiriro api ezvinhu, mumaoko aani, uye mushure mekukundikana kangani? Pamusoro pezvose, mapoda machena iwayo akanyarara haatauri, asi kukwenya kwese kwaanosiya ndiko mutauro wakavimbika.
