We followed tracks and signs of a large group of lion cubs that moved considerable distances, without the guidance or protection of adults. There were approximately ten cubs, and from the size of their spoor, they were no older than a year. These were unusual observations. Generally, lionesses give birth to small litters of 2 – 3 cubs, although they do occasionally synchronise their oestrus cycles and produce litters about the same time. However lion cubs, of that age, are mostly in the company of adults. Textbooks and the scientific literature suggest that one-year-old lions are dependent on the adult lionesses of their pride, and could not survive on their own.

我们跟踪由一大群幼狮留下足迹的其他记号，这些狮子没有其他成年狮子陪同和保护，粗略估计，这群狮子的数量接近10只，他们足迹的尺寸显示他们不会超过1岁，这是不常见的，通常情况下，母狮会生下至少2～3头幼崽，但也有个别例外的时候，然而在这个年龄段的幼狮大都有"母亲"陪同，许多书上介绍，1岁大的小狮在离开狮群母狮的照顾后是无法生存的。

"There has been a great deal of controversy lately over stamper thickness and how to measure it," says Thomas Hackl CCO of DaTARIUS Group."The Universal Stamper Checker was developed as a direct response to the demand from the industry for a test system that can not only check the quality of stampers, but is also easy to use."

"在近一段时间对于母盘的厚度和如何对其进行测量产生了较多的争论，" DaTARIUS集团的CCO Thomas Hackl介绍他们的初衷，"这个通用系统的推出直接的给予产业中无法在一个系统中对母盘的质量进行检测争论的一个有力回应，这个系统的使用十分简单。"

The Universal Stamper Checker fits into any DaTARIUS Analyzer system (CS-5 upgrade required) and is available for all stamper formats.

这个通用的母盘检测模块可以同任何DaTARIUS的测试系统配合（基于CS-5升级）并对所有母盘格式进行检测。

The results showed that the cell wall organization during anther development failed to divide into inner-wall, middle and tapetum normally, and not to provide material, energy and information transfer for the development of pollen mother cells, resulting in the occurrence of abnormal pollen mother cells separatist period; thus which could not form a normal pollen grains which led to abortion.

结果表明，不育花药壁组织在发育过程中，没有分化形成正常的内壁、中层及绒毡层，不能为花粉母细胞的发育提供物质、能量和信息的传递，造成花粉母细胞在减数分裂期发生异常，不能形成正常的四分体，因而未能形成正常的花粉粒而导致败育。
