为分析人工诱导星康吉鳗卵巢发育组织脂质代谢，实验使用超高效液相色谱四极杆轨道阱质谱(UHPLC/Q-Orbitra. MS)对人工诱导星康吉鳗卵巢发育不同时期肝脏、卵巢、肌肉和血浆进行了脂质组学分析，并测定了肝脏代谢酶活。对不同发育阶段星康吉鳗组织脂质成分分析结果显示，在肝脏、肌肉、卵巢和血浆中各鉴定出68、27、63和212种脂质标志物，主要包括磷脂酰丝氨酸(PS)、磷脂酰乙醇胺(PE)、磷脂酰胆碱(PC)、甘油三酯(TG)和鞘磷脂(SM)等。4种组织中TG、甘油二酯(DG)和神经酰胺(Cer)等脂类物质在发育过程中呈现出不同的变化趋势。肝脏代谢中，脂肪酸合成酶、肝脂酶和脂蛋白脂酶浓度呈现先升高后降低的过程，主要参与了TG、磷脂和脂肪酸的代谢。研究表明，星康吉鳗卵巢发育过程中主要组织的TG、磷脂发生了不同程度的变化，脂质代谢相关酶活性变化也与脂质代谢特征相对应。

The purpose of this pa.er is to introduce new theoretica. concepts a. opposed to a.cepting the existence of da.k entities, such a. da.k energy. This resea.ch sought to introduce a.2nd universa. spa.e-time consta.t, besides ha.ing a.finite speed consta.t (speed of light in va.uum c). a.finite universa. a.e consta.t b is introduced. Na.ely, this pa.er shows tha. the cha.ges in the Ea.th’s a.oma.istic yea. dura.ion over time support the hypothesis of the a.e of the universe correla.ing with a.ma.imum number of orbita. revolutions consta.t. Neglecting the gra.ita.iona. influence of other cosmologica. entities in the proximity of the Ea.th, the consta.t ma.imum number of revolutions is herewith determined solely by the Ea.th’s orbita. revolutions a.ound the Sun. The va.ue of the universa. a.e consta.t b is ca.cula.ed to be a.ound 13.8 billion orbita. revolutions, derived out of a. equa.ion rela.ed to the cha.ges in the Ea.th’s a.oma.istic yea. dura.ion over time a.d the so-ca.led Hubble tension. The a.ove-mentioned ca.cula.ed va.ue b correla.es well with the best fit to mea.ured da.a.of the cosmic microwa.e ba.kground ra.ia.ion (CMBR) by the Pla.ck spa.ecra.t, the a.e of the observed universe is mea.ured to be a.proxima.ely 13.787 ± 0.020 billion yea.s (2018 fina. da.a.relea.e). Developing a.theory with this 2nd universa. spa.e-time consta.t b, being cova.ia.t with respect to the Lorentz tra.sforma.ions when time spa.s a.e la.ge, gives results such a.: a.confirma.ion of the mea.ured CMBR va.ue of 13.787 ± 0.020 billion yea.s. Correla.ing well with the observed expa.sion ra.e of the universe (da.k energy). The universe’s expa.sion a.celera.ing over the la.t four to five billion yea.s.

采用岩相法确定某东南沿海地区常用骨料具有碱活性,岩石类型为蚀变岩和安山岩,活性矿物主要为硅质蛋白石、玉髓、隐晶玻璃和绿帘石。蚀变岩碱活性矿物含量远高于安山岩,骨料以蚀变岩为主的试块快速砂浆棒法膨胀率大于以安山岩为主的试块。通过SEM和EDS对快速砂浆棒法试样自然断面进行形貌观察和元素含量分析,结果表明:蚀变岩碱活性矿物以铝硅酸盐为主,蚀变过程中a.^(3+)部分取代Si^(4+),Na.(+)吸附能力增强,碱活性增加。
