Cov Ntsiab Cai Tswjfwm rau Rail Spike Pull- tawm Kev Tiv Thaiv thiab Anchorage Zoo
Dab tsi yog peb yam tseem ceeb ntawm kev rub rub tawm - tawm tsam?
Ua ntej, anchoring khoom muaj zog. Qhov thib ob, qhov kev huv ntawm phab ntsa. Thib peb, kev tsim kho zoo nrog rau kev sib xyaw, txhaws thiab kho. Tag nrho peb yuav tsum tau tswj xyuas kom ruaj khov siab rub- tawm tsis kam.
Vim li cas hmoov av thiaj li txo rub- tawm tsis kam?
Plua plav tsim txheej txheej sib cais ntawm tus neeg sawv cev thiab pob zeb, tiv thaiv kev sib txuas. Lub interface ua nplua, ua rau kev sib cais nyob rau hauv load. Plua plav tuaj yeem txo rub- tawm ntawm kev tiv thaiv ntau dua 40%. Kev ntxuav yog qhov tseem ceeb tab sis feem ntau tsis saib xyuas.
