例句與造句

1. in the orthorhombic phase, the desorption activation energy has an obvious increase with the increase of temperature, while it varies smoothly in the tetragonal phase as the temperature increases
   當(dāng)樣品為正交相時(shí)，脫附活化能隨著溫度的升高明顯增加，而四方相時(shí)則變化比較平緩。
2. the xrd peak of 2 6 = 45 ? was gradually widened with the increasing of pt . it might mean that rhombohedral phase was gradually converted to tetragonal phase in this system
   在pmn-pt系統(tǒng)中，隨著pt含量的增加，2=45的xrd特征峰出現(xiàn)明顯峰寬化現(xiàn)象，表明pmn-pt由三方相逐步向四方相轉(zhuǎn)化。
3. the tetragonal phase of pbtio3 is very stable owing to its large tetragonal strain, and relatively small tetragonal stain of batio3 is an important reason for its low-temperature phase transition
   由于鈦酸鉛具有較大的四方應(yīng)變，使得其能夠在四方相穩(wěn)定下來，而鈦酸鋇較小的四方應(yīng)變是其仍能夠發(fā)生低溫鐵電相變的一個(gè)重要原因。
4. the results indicate that the osc and reductibility of the ceo2-zro2 solid solution are not improved after adding e ions . while after incorporating m ions into the ceo2-zro2, the samples exhibit high osc probably by reason that m-o itself also has good capability of oxygen adsorption . after aged at high temperature, the osc of these samples decreased dramatically for the formation of m2o3 and mo2 and for the separation of tetragonal phase of ceo2-zro2
   在ceo_2-zro_2固溶體中引入m后，由于m-o本身具有氧吸附性能，使得樣品表現(xiàn)出很好的儲(chǔ)氧能力，但經(jīng)過高溫老化后，原四方晶相的ceo_2-zro_2固溶體發(fā)生了相分離，且生成了大量的m_2o_3和mo_2相，使得樣品的儲(chǔ)氧量急劇減少，可還原性能明顯降低。
5. the addition of y-zro2 improves the fracture toughness of pcd and the grinding ratio also increases with the y2o3 content increasing . the optimum comprehensive properties of pcd can be achieved as the y-zro2 powders contain 2mol % y2o3 . aluminum addition in si3n4 or si3n4 bond pcbn can prevent y-zro2 powders from forming the nontransformable tetragonal phase
   在si_3n_4及si_3n_4中介結(jié)合的pcbn中加入適量的al作為燒結(jié)助劑，可以避免不可相變的t相zro_2形成，使應(yīng)力誘導(dǎo)相變?cè)鲰g高溫高壓燒結(jié)的氮化硅系陶瓷成為可能。
6. It's difficult to find tetragonal phase in a sentence. 用tetragonal phase造句挺難的
