纤毛虫的

A general trend in the research of symbiosis in ciliates is further exploration of the influence of the symbiont on the gene structure and gene expression of the host. The expected results will contribute to a better understanding of the regulatory mechanisms controlling the interaction,the exchange of substances between the host and symbiont at a molecular level, and the pattern of life processes sur rounding the relationship between cellular structures and functions in eukaryocytes.

作者推测，探索共生体对宿主基因结构及其表达产物的影响可能是对纤毛虫中共生作用研究的主要趋势，这对于深入了解真核细胞中宿主-共生体双方的相互作用、物质交流在分子水平上的调控机理、细胞结构与功能的关系等细胞生命活动规律是有意义的。

The protozoa distribution varies with the CWD ages. Its number and the numbers of three main faunas increase with the going up of CWD ages. The percentages of Flagellate fauna, Sarcodina fauna and the Infusorians fauna percentage are respectively 26％-27％, 73％ and 0.06％-0.07％.

原生动物的分布随着倒木年龄的增长，其数量以及原生动物的三大类群的数量均有所增加，鞭毛虫类群基本占26％～27％之间，肉足虫类群基本占73％左右，纤毛虫类群基本占0.06％～0.07％之间。

It is suggested that the algae symbiot can affect host organellar function,quantity and location, stimulate the food uptake and digestive activity, restrain the functional activity of the organelle, change the gene expression and cause the change of genome structiure in the P. bursaria-chlorellae system.

据结果推测，纤毛虫中的藻类共生体可影响宿主细胞中胞器的功能、数量和分布，可影响细胞核核仁的数量和分布；可影响宿主细胞的形态、生长、抗氧化能力及胞质糖含量；可影响宿主细胞的食物摄取及相关胞器的消化活性，抑制宿主胞器的功能活动；并可改变宿主细胞基因的表达，导致细胞基因组结构的变化。

Genome-wide DNA rearrangements occur in many eukaryotes but are most exaggerated in ciliates, making them ideal model systems for epigenetic phenomena.

全基因组的DNA重排的发生在许多真核生物，但最夸张的在纤毛虫，使他们的理想模型系统的后生现象。

Mm, glabrous; blade reflexed, linear-lanceolate, glabrous. Leaves 3 or 4 per ultimate branch; sheath margins initially ciliate; auricles purple, falcate, small; oral setae erect, gray-brown; ligule arcuate, margins initially ciliate; blade lanceolate,(7–)10–16 × 1–1.7 cm, proximally white-gray pubescent, secondary veins 4-paired, transverse veins obscure, base cuneate, one margin spinescent-serrulate, other margin obscurely so.

每末级的分枝留下3或4；鞘边缘最初具缘毛；叶耳紫色，镰刀形，小；口头的刚毛直立，灰棕色；叶舌弧曲，最初给纤毛虫镶边；叶片披针形，( 7-)10-16 * 1-1.7 厘米，下部白色灰色短柔毛，4配对的次脉，不明显的横向脉，基部楔形，具刺有细锯齿的一边缘，如此的其他边缘不明显。

Culm sheaths yellow-green or pale red-brown, becoming straw-colored, with variably sized brown spots, base edged with white pubescence; auricles and oral setae absent; ligule yellow-green, truncate or weakly convex at apex, very short, 1–2 mm, margin longer pale green ciliate; blade reflexed, green, with yellow margins, linear, flat or crinkled in upper sheaths.

竿箨黄绿色或者苍白的红棕色，变得稻草色，带有易变依大小排列的棕色的点，基础随着白色的青春期推进；叶耳和口头的刚毛无；叶舌黄绿色，削去或者身体虚弱凸在先端，非常短，1-2毫米，边更长的苍绿色纤毛虫；反折，绿色的叶片，具黄边缘，在上面鞘内皱曲的线形，平或。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
