Corona tsi lajang ai pen gaw, arung arai ni a ntsa na n-gun atsam ni hpe chyam dinglik na matu lang ai arung arai langai rai nna, hka lim ai lam, n-gun rawng ai lam, ntsa na n-gun atsam ni hpe jep joi ai lam galaw ai. Lahta na gaw corona tsi lajang ai pen hpe lang na matu madung lahkam ni rai nga ai:
Hkyen lajang ai lam: Na a bungli shara hpe san seng ai hte san seng hkra galaw na matu, n san seng ai lam ni hpe chyam dinglik ai lam hpe n hkra hkra galaw u. Bai nna, chyam yu na matu ra ai arung arai sample hpe mung hkyen lajang u.
Corona tsi lajang ai pen hpe lata ai: Chyam yu na arung arai ni a atsam ni hpe madung tawn nna, htap htuk ai shara kaw na corona tsi lajang ai pen hpe lata u. Corona tsi ladat amyu myu hta n bung ai npu na n-gun atsam ni a matu htuk manu ai coating arung arai ni n bung ai rai na re.
Corona tsi lajang ai pen hpe masat da ai: Corona tsi lajang ai pen nkau mi gaw, pen tip hpe ngang grin hkra galaw lu na matu, lang shagu garai n lang shi yang, calibration galaw ra ai. Ndai calibration galaw ai lam hta, hkang zing ai ntsin hte arung arai ni lawm mai ai.
Coating hpe hkyen lajang ai: Arung arai sample hpe madang ntsa kaw chyam yu na matu tawn da u. Ntsa lam gaw katsi ai, san seng ai, nhprang arai hte sau n lawm ai hpe sadi u.
Line langai hpe jai lang ai: Lata da ai corona tsi lajang ai pen hpe, chyam dinglik na matu, n-gup magap a ntsa e, loi loi hte tawn da nna, pen tip hpe, dai arung arai ni hte matut mahkai shangun ai. Pen tip gaw liquid kaji langai hpe shapraw ya nna, n-gun n rawng ai line hpe shabyin ya na re. Hpang na shadawn shadang a matu line galu ai hpe sadi u.
Coating hpe yu ai: Coating a akyang lailen hpe arung arai ntsa kaw yu u. Dai sumla hkrung gaw, chyam bra ai, chyam bra ai, n-gun yawm ai zawn re ai lam amyu myu hku nna bai htang na re. Ndai hkam sha lam ni gaw, dai arai a ntsa na n-gun atsam hte hka lim ai lam hpe madun dan ai.
Shadawn shadang mahtai: Coating a akyang lailen gaw, dai arai a ntsa na n-gun atsam ni a lam hpe chye lu ai. Corona tsi lajang ai pen nkau mi hta, npu na n-gun manu ni hpe shadawn shadang hku jep joi ai lam galaw lu ai scale (sh) masat kumla ni lawm mai ai.
Analysis hte lachyum shaleng ai lam: Mu mada ai mahtai ni hpe, arung arai a jai lang ra ai lam ni hte myit mada da ai bungli galaw ai lam ni hte shingdaw nna sawk sagawn na. N bung ai coating akyang lailen ni gaw, npu na n-gun madang n bung ai hpe madun dan lu ai, dai gaw hka lim ai lam hte n-gun hpe hkra machyi shangun lu ai.
Results: Hpang na sawk sagawn ai lam hte reference a matu chyam dinglik ai mahtai ni hpe ka da u. Recording gaw arung arai ni a galai shai ai lam ni hpe hkan tam na matu karum ya nna, dai ni hpe grau kaja hkra galaw ya ai.
San seng ai lam hte gram lajang ai lam: Hpang na chyam dinglik ai lam ni hta awu asin byin ai lam hpe makawp maga na matu, lang ngut ai hpang, corona tsi lajang ai pen a npawt hpe jasan jaseng u. Corona tsi lajang ai pen a bungli galaw ai lam hpe ayan jep joi nna, galaw shapraw ai wa a hpaji jaw ai lam ni hte maren, gram lajang na.
