Qhov sib lawv liag hauv qhov piv txwv tsis yog monotonic tab sis nws ua ke. Nco ntsoov tias peb tuaj yeem ua ntau qhov sib txawv ntawm qhov theorem no. Yog hais tias {ib} yog bounded saum toj no thiab nce ces nws converges thiab zoo li yog tias {ib} yog bounded hauv qab no thiab txo ces nws converges.
Puas yog tag nrho cov monotonic sequences convergent?
ib ntus (a ) yog monotonic nce yog tias a +1≥ a rau tag nrho n ∈ N. Cov kab ke yog nruj me ntsis monotonic nce yog tias peb muaj > hauv lub ntsiab lus. Monotonic txo sequences raug txhais zoo sib xws. A bounded monotonic nce ib theem yog convergent.
Puas yog cov koob yuav tsum yog monotonic los sib sau ua ke?
Tsis yog txhua qhov kev sib tw, zoo li (−1)n, sib koom ua ke, tab sis yog tias peb paub tias qhov kev sib tw bounded yog monotone, qhov no yuav hloov. Yog tias ib qho ≥ ib + 1 rau tag nrho n ∈ N. Ib ntu yog monotone yog tias nws nce lossis qis. thiab bounded, ces nws converges.
Yuav ua li cas tsis muaj bounded sequence yuav convergent?
Yog li kev sib tw tsis tuaj yeem sib koom ua ke.
Nws txhais li cas yog tias ib ntus tsis yog monotonic?
Yog tias ib ntus qee zaum nce thiab qee zaum qis dua thiab yog li tsis muaj kev coj ua zoo ib yam, nws txhais tau tias qhov sib lawv liag tsis yog monotonic. Nyob rau hauv lwm yam lus, ib tug tsis-monotonic ib theem zuj zus rau ib feem ntawm qhov sib lawv liag thiab txo rau lwm tus.

Vim li cas kev sib txuas sib txuas yog qhov tseem ceeb?
Cov lattice reciprocal plays lub luag haujlwm tseem ceeb hauv kev tshawb fawb feem ntau ntawm cov qauv ntu, tshwj xeeb hauv kev xav ntawm kev sib txawv. Nyob rau hauv neutron thiab X-ray diffraction, vim yog Laue tej yam kev mob, qhov sib txawv ntawm cov khoom xa tuaj thiab cov duab hluav taws xob sib txawv ntawm cov siv lead uayog cov kab lattice vector .
Puas kev sib txuas lus tsis zoo kuj yog ib qho khoom ntawm kev sib txuas lus?
Kev sib txuas lus tsis zoo ("mis" + "kev sib txuas lus") txhais tau tias yog tsis ua tiav kev sib txuas lus kom txaus thiab zoo Nws yog ib hom kev sib txuas lus teeb meem. … Hom kev sib txuas lus tsis zoo tam sim no tuaj yeem raug cais raws li lub hauv paus ntawm kev tsis sib haum xeeb txog txoj cai sib txuas lus .
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
Puas muaj cov kab mob uas muaj cov kab sib txuas sib txuas?
Cov leeg mob plawv yog ceg thiab muaj cov kab sib txuas, uas cov leeg pob txha tsis muaj . hom xovtooj twg muaj intercalated discs? Cov hlwb yog qhov tshwj xeeb, ntawm cov leeg nqaij, vim tias lawv tau txuas rau ib leeg los ntawm kev sib cuam tshuam discs - cov qauv uas tsuas pom muaj nyob hauv cov leeg mob plawv .
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
