后生

Author has described the existing problems in the production after being changed from cylindrical gasifier to conical gasifier from aspects of pressure drop of system,material balance,heat balance,slag transition area,ash tray diameter,flow protection plate,entrainment under gasifier and gasification strength etc.

从系统阻力、物料平衡、热量平衡、炉渣过渡区、灰盘直径、防流板、炉下带出物、气化强度等方面阐述了造气煤气炉由直筒形改为锥形炉后生产中存在的问题；论述了煤气炉阀径与工艺流程的选配原则；阐明了锥形煤气炉的生产水平低于直筒形炉气炉的观点。

作者覃彪喜，80后生，此人是愤青，但不愣头，敢做敢为，正在创业路上。

Particular configurations on bedding planes and on the surface perpendicular to the bedding planes lead to different explanations for the genesis of these silty dykes:(1) they are considered as the oldest trace fossils of metazoan according to the spindle-crack of siltstones on the bedding plane and the sand-filling tube configurations on the surface perpendicular to the bedding plane;(2) they are considered as the liquefied sand-veins induced by earthquake according to the sinuous configuration of siltstone dykes on the surface perpendicular to the bedding plane and the obvious liquation feature.

由于该粉砂岩岩墙在层面上和层内具有特别的形态，因而对其成因具有多种解释：在层面上呈纺锤状粉砂岩裂缝以及在层内呈砂质充填管形态，从而被认为是最古老的后生动物遗迹化石；在层内呈弯弯曲曲的粉砂岩岩墙以及明显的流体化作用特点，所以又被解释为地震振荡作用形成的液化砂岩脉。

This Review discusses current advances in our understanding of the origin, biogenesis, and mode of action of plant miRNAs and draws comparisons with their metazoan counterparts.

本文对植物miRNAs的生物起源和作用模式进行了讨论，并对与它们配对的后生动物进行了对比。

The characterof gas emission and the degree of coalification are relative to the breakdown strength ofcoal-bed.

淮北宿东矿区和淮南谢二矿的某些煤层受到过强烈的后生构造破坏，煤体的破碎强度与矿井瓦斯及煤的煤化程度的加深存在正相互关系。

The metazoans in the Wenghui Biota had radiate symmetrical animals, including Porifera, Ctenophora, Cnidaria, and Trilobozoas, and bilateral symmetrical animals, including Annelida and possible Mollusca.

瓮会生物中宏体后生动物有海绵类、栉水母类、刺胞类和三叶类等两胚层辐射对称动物以及环节类和可能的软体类等三胚层两侧对称动物。

The numerous macro-plants during the Doushantuoian were branching and semi-floated and erected on seafloor. They advanced the photosynthetic efficiency and increase oxygen in water to improve in environment for metazoans; and they served as a primary producer in the paleoecosystem to provide an alternative and new food of metazoan.

陡山沱期的宏体藻类多分枝并直立固着于海底，提高了光合作用的效率，增加了海中水体中的含氧量，不仅改善了环境，为依赖一定氧而生活、生长和繁殖的后生动物给予了必要的支持，而且作为生态系统中的必要基础，为宏体后生动物的快速发展和演化提供了一个新的食物源。
