文中详细分析了各项因素的交互作用，并找出了最佳的综合工艺条件。

Isolates CNR-1 and CNR-2 were from Brassica napus; CNA-1and CRW-1 from Rhododendron simsii and Oxalis corymbosa respectively. All isolates grew well in R-2 liquid medium and exhibited contractive movements. The colonies of all isolates were circinal and grain-like in solid medium. Through electron microscopy, all isolates exhibited helicity during their growth phase. All isolates could pass through a 0.22 μm filtrate membrane and resist to penicillin (2000 U/mL). They must grow in medium with serum.

这4株螺原体在R-2液体培养基中生长良好，都能通过孔径为0.22 mm的微孔滤膜；在R-2固体培养基上呈圆形或颗粒状菌落，菌落直径约50~600 mm；在生长的某个阶段可呈典型的螺旋状，菌体直径为37.04~370.40 nm，长度约0.89~11.88 mm；它们都能利用葡萄糖作为碳源，不能利用尿素；在不含胎牛血清的R-2培养基中，它们都不能生长；菌株CNR-1、CNA-1能强烈代谢精氨酸，而CNR-2和CRW-1不能代谢精氨酸；在氨苄青霉素钠浓度高达2000 U/mL的R-2培养基中，分离菌株生长良好。

The mechanical power of falling water is an age-old tool .of all the renewable energy sources that generate electricity ,hydropower is the most often used .it is one of the oldest sources of energy and was used thousands of years ago to turn a paddle wheel for purposes such as grinding grain .in the 1700's ,mechanical hydropower was used extensively for milling and pumping .

减少水的机械动力，是一个古老的工具，所有的可再生能源。是发电，水电是最常用的。它是最古老的能源来源之一，是用几千年前把桨车轮的用途，例如磨粒在1700年，机械水力发电。被大量用于加工和抽水。

Grain yield showed a parabolic curve relationship with LAI of heading stage.

占总叶面积的比例为84％和90％左右。

The main results as follows:1. Dry weight of heading stage showed a parabolic curve relationship with yield. And grain yield correlated well with dry matter accumulation after heading and total dry weight of muturing stage. The accumulation of dry matter from N-n to heading stage correlated with photosynthetic potential.

水稻抽穗期干重与产量呈抛物线关系，抽穗后干物质积累量和成熟期总干重与产量均呈极显著线性正相关。N-n期至抽穗期干物质积累量随着光合势的增加而增加，两者相关达到显著水平，而与净同化率关系不密切。

Second, since the rise of the peasant movement the price of grain has dropped -- it was six yuan a picul last spring but only two yuan last winter -- and the problem of food has become less serious for the people.

二是农民运动起后，谷子价廉，去春每担六元的，去冬只二元，民食问题不如从前那样严重。

It is obvious that grain size plays a very important role in the plastic deformation of the poly-grained IQCs.

这说明晶粒的大小在准晶多晶的塑性形变中的影响非常大。

Yes, it was said for us; because it is right for the ploughman to do his ploughing in hope, and for him who is crushing the grain to do his work hoping for a part in the fruits of it.

9：10 不全是为我们说的麼，分明是为我们说的，因为耕种的当存著指望去耕种，打场的也当存得粮的指望去打场。

In many gymnosperms the nuclei divide within the pollen grain to produce a small number of cells (2-40 depending on the group )representing the male prothallus.

在许多裸子植物中，细胞核在花粉粒中分裂以产生少量的细胞（2～40个，取决于不同种类），代表雄性原叶体。

The results showed that length from flag leaf pulvinus to spike base has the largest coefficient of variance of 42.1% and 37.2% in both DS and WW environments, respectively, while the spikelet per spike has the smallest CV of 6.4% and 5.7%. Under different water regimes, spike number per plant, effective spikelet per spike and peduncle length contribute a lot to the stable grain yield. Genetic diversity indices of DTI were from 1.95 to 2.07, with an average value of 2.02. Based on the DTI of agronomic traits, all accessions could be clustered into seven groups, the first and third groups are not sensitive to the water regimes, and the second group is more suitable for planting in dryland.

结果表明：在雨养和灌溉条件下，穗叶距的变异系数最高，分别为42.1%和37.2%，单穗总小穗数的变异系数最低，为6.4%和5.7%；不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；性状耐旱指数的多样性指数在1.95到2.07之间变化，平均值为2.02；根据性状耐旱指数将供试材料分为7个类群，其中第I、第III类群材料表现为对水分条件不敏感，而第II类群材料更适于在干旱条件下种植。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
