①密度。指單位(wei)體積工(gong)(gong)(gong)地(di)建(jian)筑(zhu)木(mu)(mu)方(fang)(fang)(fang)的重(zhong)量。工(gong)(gong)(gong)地(di)建(jian)筑(zhu)木(mu)(mu)方(fang)(fang)(fang)的重(zhong)量和體積均受含水率影(ying)響(xiang)。工(gong)(gong)(gong)地(di)建(jian)筑(zhu)木(mu)(mu)方(fang)(fang)(fang)試樣(yang)的烘干重(zhong)量與其飽和水分(fen)(fen)時(shi)的體積、氣(qi)干時(shi)的體積及(ji)爐(lu)(lu)干時(shi)的體積之比，分(fen)(fen)別稱為氣(qi)干密度、基(ji)本密度及(ji)爐(lu)(lu)干密度。工(gong)(gong)(gong)地(di)建(jian)筑(zhu)木(mu)(mu)方(fang)(fang)(fang)密度隨樹種而(er)異。大多數工(gong)(gong)(gong)地(di)建(jian)筑(zhu)木(mu)(mu)方(fang)(fang)(fang)的氣(qi)干密度約(yue)為0.3～0.9克/厘(li)米。密度大的工(gong)(gong)(gong)地(di)建(jian)筑(zhu)木(mu)(mu)方(fang)(fang)(fang)，其力(li)學強度一(yi)般較高。

②工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)含(han)水(shui)(shui)率。指工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)中水(shui)(shui)重占烘(hong)干工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)重的(de)(de)(de)百分(fen)數。工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)中的(de)(de)(de)水(shui)(shui)分(fen)可分(fen)兩部(bu)(bu)分(fen)，一(yi)部(bu)(bu)分(fen)存(cun)在于(yu)工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)細胞(bao)胞(bao)壁(bi)內，稱為(wei)吸(xi)附水(shui)(shui)；另一(yi)部(bu)(bu)分(fen)存(cun)在于(yu)細胞(bao)腔和(he)細胞(bao)間隙(xi)之間，稱為(wei)自由水(shui)(shui)(游離水(shui)(shui))。當吸(xi)附水(shui)(shui)達到飽(bao)和(he)而(er)尚無自由水(shui)(shui)時，稱為(wei)纖(xian)(xian)維(wei)(wei)飽(bao)和(he)點(dian)。工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)的(de)(de)(de)纖(xian)(xian)維(wei)(wei)飽(bao)和(he)點(dian)因樹種而(er)有差(cha)異(yi)，約在25～35％之間。當含(han)水(shui)(shui)率大于(yu)纖(xian)(xian)維(wei)(wei)飽(bao)和(he)點(dian)時，水(shui)(shui)分(fen)對(dui)工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)性質的(de)(de)(de)影響(xiang)很(hen)小。當含(han)水(shui)(shui)率自纖(xian)(xian)維(wei)(wei)飽(bao)和(he)點(dian)降低時，工(gong)(gong)(gong)地(di)建(jian)筑木(mu)(mu)(mu)方(fang)(fang)(fang)(fang)的(de)(de)(de)物理(li)和(he)力學性質隨(sui)之而(er)變化(hua)。

檢驗建筑(zhu)木(mu)方木(mu)料(liao)(liao)的(de)含(han)(han)水(shui)量方式 1、手掂法(fa)(fa)：輕(qing)(qing)輕(qing)(qing)地(di)估量幾塊(kuai)木(mu)料(liao)(liao)，含(han)(han)水(shui)量小的(de)木(mu)料(liao)(liao)會較為(wei)輕(qing)(qing)，含(han)(han)水(shui)量大的(de)木(mu)料(liao)(liao)就顯(xian)著重一(yi)些。 2、手去摸(mo)法(fa)(fa)：將手掌心平放到木(mu)料(liao)(liao)表面，木(mu)方，體會它的(de)濕冷水(shui)平。 3、敲釘(ding)法(fa)(fa)：用長釘(ding)輕(qing)(qing)輕(qing)(qing)地(di)敲入(ru)(ru)木(mu)料(liao)(liao)，干躁得好的(de)木(mu)料(liao)(liao)通常(chang)非常(chang)容易釘(ding)入(ru)(ru)，而環(huan)境(jing)濕度大的(de)木(mu)料(liao)(liao)釘(ding)入(ru)(ru)就艱難。 日照市(shi)(shi)嵐山區永榮實木(mu)家具廠，坐(zuo)落(luo)于山東(dong)的(de)東(dong)南(nan)(nan)部地(di)區，優美環(huan)境(jing)的(de)日照港，地(di)近黃海，南(nan)(nan)鄰江(jiang)蘇省徐州市(shi)(shi)、江(jiang)蘇連云(yun)港兩(liang)市(shi)(shi)。木(mu)料(liao)(liao)資源標準獨厚，道路運輸十分便捷，企業是(shi)一(yi)家技術專業著眼于木(mu)材生(sheng)(sheng)產制造、生(sheng)(sheng)產加工、批一(yi)體化(hua)的(de)智能化(hua)綜(zong)合性公司。
