The only alternative and referential way to predict the phase transformation temperature is to make use of the continuous cooling transformation diagrams, which are measured dilatometer curves that have not taken the effect of practical welding conditions into account.

由于焊接过程的瞬时性和焊接热影响区温度场、应力场的复杂性，该区域的组织转变往往并不完全遵守热处理条件下CCT 图所反映出的相变规律，因此为了提高焊接接头的性能，有必要深入研究真实焊接条件下热影响区组织的相变规律，尤其是马氏体组织的相变规律，因为在含碳量较高或合金元素较多的情况下，这两类钢的淬透性较强，在焊接热影响区极易形成高硬度马氏体组织，从而严重影响焊接接头的性能。

For a heterogeneous elastic solid consisting of two homogeneous layers, three homogeneous layers whose shear wave velocities increasing with depth, or three homogeneous layers whose interlayer has high velocity, if there are multi-mode dispersion curves, the phase velocity V〓 of the first mode will close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, and V〓 of the first mode will close up to the Rayleigh wave velocity of the top layer when f→∞.

由多导波模式的相速度频散曲线还可知，对于二层固体介质、结构层的横波速度随深度而递增的三层固体介质、含硬夹层的三层固体介质而言，若频率f→OHz，其基阶模式的瑞利波相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式的V〓→V〓（V〓为最上层介质的瑞利波速度）；因此，随着频率f逐渐升高，野外实测的瑞利波相速度V〓曲线应该主要为基阶导波模式。

Compared with adult mothers, teenage mothers had higher incidence of abortion, more with domestic violence experience, more with lower education, more being unemployed, more with smoking or alcohol drinking habits, and more with depressive symptoms. Primary caregivers of the firstborn were more the parents of the mothers and less the mothers themselves and the biological fathers in teenage mother group. Teenage mothers more lived with the parents of the biological fathers. More income came from the parents of the biological fathers and less from the biological fathers or cohabited partners. Percentage of self-perceived low family income and proportion of receiving social welfare money were higher.

未成年母亲相较於成年母亲而言，呈现出相当不利的情况，包含有较多的堕胎及家庭暴力经验、较低的教育程度、职业较多为无业或家庭主妇、较多的抽菸和喝酒习惯、较多有忧郁倾向；第一个小孩的主要照顾者方面，较多为女方父母照顾、较少为自己及小孩生父，较多与公婆同住；家庭收入主要来源方面，较多为男方父母、较少为先生或同居男友。

虽然使用机率资料连结演算法之多使用者侦测器可以得到近乎最佳化多使用者侦测器的效能，但其计算复杂度相较於最小均方误差多使用者侦测器仍然偏高。

In aspect of investigation on the binary phase splitting grating, Dammann grating, rectangle grating and also coordinate-phase modulate grating have been studied respectively. Detail analysis shows that the grating phase angle can inflect greater than coordinate to the splitting efficiency and equality rate.
