查询词典 immature

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。

那个寄托已经离开，永远不会再回来，而我也不想他回来。

At 21 DAG, the newly established cambium cell started periclinal division, which would result in the production of phloem outwards and xylem inward. The 11-23 immature xylem cell layers beneath the surface continued their differentiation into mature xylem cells.

表面下7-11层未成熟木质部细胞在第7-14 DAG左右脱分化形成新的形成层。21 DAG，再生形成层开始平周分裂，产生新的韧皮部和木质部。11-23层未成熟木质部细胞继续分化为成熟木质部。

Result The cultured DC from mouse bone marrow displayed the typical morphological characteristics of DC. Immature DC, which had high expression in CD11c and low expression in MHCⅡ and CD86, could phagocytize antigen. Mature DC, which had high expression in CD11c, MHCⅡ and CD86, could stimulate allogenic mixed lymphocyte proliferation.

未成熟DC的细胞表型为CD11c、MHCⅡ、CD86，具有极强的抗原吞噬能力；未成熟DC经LPS刺激培养后可转变为成熟DC，细胞表型为CD11c、MHCⅡ、CD86，可显著刺激同种异体混合淋巴细胞增殖。

The friable embryogenic callus with small grains and without proembryo formation was screened in the process of continuous subcultures for 4~6 times on the medium with low content of sucrose from embryogenic cultures induced from immature embryos in litchi (Litchi chinensis Soon.). The well-scattered embryogenic cell suspensions could be rapidly established from the friable embryogenic callus in 2 liquid initial MS media respectively supplemented with 2,4-D 2 mg/L or 2,4-D 2 mg/L, KT1 mg/L and AgNO3 5 mg/L shaking at 100~120 r/min within 10-14 days.

荔枝幼胚诱导的胚性培养物在低糖条件下连续继代4~6次左右，可筛选到颗粒细小、不含原胚的松散型胚性愈伤组织；以这种松散的胚性愈伤组织作为起始材料，在附加2，4-D 2mg/L或2，4-D 2mg/L、KT1 mg/L、AgNO3 5mg/L的MS液体启动培养基上振荡培养（100~120 r/min）10~14 d，即可建立起分散性良好的胚性悬浮细胞系。

With immature embryos of Citrus grandis'Guanximiyou' as material, the effect of the three factors, enzyme treating time, pycnosis treating time in ice water and dyeing, were studied in the process of single chromosome microdissection technique.

以'琯溪蜜柚'幼胚为材料，对单染色体微分离制片过程中酶解时间、冰水固缩时间和染色三因素的影响效果进行了研究。

Results: Of all the semen samples, 8 were HCMV positive, 4 HSV-Ⅱ positive, but none were both HCMV and HSV-Ⅱ positive. HCMV late antigens were positively and HCMV early antigens negatively expressed in the spermatogenic cells of the 8 HCMV positive cases. In the 4 HSV-Ⅱ positive cases, 3 were positively and 1 weakly positively expressed. In the semen of the 12 positive cases were found large numbers of immature spermatogenic cells, with different manifestations of apoptosis, such as chromatin pycnosis, vacuoles, damaged nuclear membrane, and apoptotic bodies, but without virus infection-induced specific morphological alteration.

结果：83例精液样本PCR检测HCMV阳性8例，HSV-Ⅱ阳性4例，未发现2种病毒同时阳性病例。8例HCMV阳性病例ICC标记生精细胞HCMV晚期抗原均见阳性表达，HCMV早期抗原均为阴性表达；4例HSV-Ⅱ阳性病例ICC标记生精细胞3例阳性表达，1例弱阳性。12例病毒阳性病例均发现较多未成熟生精细胞，并有不同程度的核染色质固缩、出现空泡、核膜破损、核崩解、凋亡小体等凋亡现象，但未能找到病毒感染的特异性形态学改变。
