!MATERIAL¶

Material xossalarini aniqlash

Agar material xossasi haroratga bog‘liq bo‘lsa, tegishli haroratlar bo‘yicha jadval ko‘rinishida kiritish mumkin.

1-qator

!MATERIAL, NAME=<name> [, ixtiyoriy parametr]

Parametr
`NAME`	Material nomi (majburiy)
`ITEM`	Xossa bandlari soni (ixtiyoriy; tashlab ketilsa 1)
`INPUT`	Tashqi fayl nomi (ixtiyoriy)

Parametr nomi	Parametr qiymati	Mazmuni
`NAME`	<name>	Material nomi
`ITEM`	<ITEMnum>	Foydalanuvchi belgilaydigan xossa bandlari soni
`INPUT`	<filename>	Tashqi fayl nomi (ixtiyoriy); 2-qator va undan keyingi qatorlar bilan birga ham ishlatilishi mumkin

2-qator va undan keyin

(2-qator)  !ITEM=1, SUBITEM=<k>
(3-qator)  VAL1-1-1, VAL1-1-2, … VAL1-1-k, TEMP1-1
(4-qator)  VAL1-2-1, VAL1-2-2, … VAL1-2-k, TEMP1-2
...

(L+2-qator) VAL1-L-1, VAL1-L-2, … VAL1-L-k, TEMP1-L

Quyidagilar !ITEM=<ITEMnum> gacha takroran aniqlanadi

Subparametr (`!ITEM` uchun)
`SUBITEM`	Har bir xossa bandida aniqlanadigan subxossa bandlari soni
	(Ixtiyoriy; tashlab ketilsa 1)

Subparametr nomi	Parametr qiymati	Mazmuni
`SUBITEM`	<subITEMnum>	Foydalanuvchi belgilaydigan subxossa bandlari soni

【m-chi xossa haroratga bog‘liq bo‘lsa】

Haroratga bog‘liq jadvaldagi bandlar soni N bo‘lsa, quyidagicha kiriting:

!ITEM=m, SUBITEM=k
VALm1-1, ..., VALm1-k, TEMPm1
VALm2-1, ..., VALm2-k, TEMPm2
...
VALmN-1, ..., VALmN-k, TEMPm-N

O‘zgaruvchi nomi	Atribut	Mazmuni
VALmn-k	R	Xossa qiymati (haroratga bog‘liq)
TEMPmn	R	Tegishli harorat

TEMPm1 < TEMPm2 < ... < TEMPmN sharti bajarilishi kerak.

Harorat TEMPm1 dan kichik yoki teng bo‘lsa VALm1, TEMPmN dan katta yoki teng bo‘lsa VALmN ishlatiladi.

【m-chi xossa haroratga bog‘liq bo‘lmasa】

!ITEM=m, SUBITEM=k
VALm1-1, ..., VALm1-k
VALm2-1, ..., VALm2-k
...
VALmN-1, ..., VALmN-k

O‘zgaruvchi nomi	Atribut	Mazmuni
VALmn-k	R	Xossa qiymati (haroratga bog‘liq emas)

Izoh:

Material nomi takrorlansa, xato yuz beradi.

!SECTION opsiyasida havola qilingan MATERIAL aniqlanmagan bo‘lsa, xato yuz beradi.

!ELEMENT opsiyasida MATITEM parametri orqali har bir element uchun xossa kiritilgan bo‘lsa, shu qiymat ustuvor ishlatiladi. Bu holda !MATERIAL opsiyasi bilan kiritilgan xossa qiymatlari ishlatilmaydi.

!ITEM=m subopsiyalari soni ITEM parametridagi son bilan mos kelmasa yoki aniqlanmagan subopsiya mavjud bo‘lsa, xato yuz beradi.

!ITEM=m subopsiyalari m qiymatining o‘sish tartibida joylashishi shart emas.

SUBITEM=k subopsiyasi va haroratga bog‘liqlik ishlatilganda tashlab ketilgan qiymat 0.0 bo‘ladi.

Haroratga bog‘liqlik ishlatilganda qiymatlar past haroratdan yuqori haroratga qarab aniqlanishi kerak.

Haroratga bog‘liqlik ishlatilganda bir xil harorat ikki yoki undan ko‘p marta berilsa, xato yuz beradi.
