Soil grain grade composition of soil physical and chemical properties of influence， this is the method of using BiChongJi southwest area into several rock soil (purple soil， lime soil， volcanic dust) grain Some conclusions:Southwest area into rock (soil， lime， purple soil and volcanic dust particles in the sand， which accounts for more than viscous grain powder， small 2 the same soil layer， due to the different leaching deposition etc， on the effect of soil layer of grain composition class there are differences of sand soil， black limestone and clay content with the increase of depth and And the sand and volcanic ashes viscous grain content decreased with 3 the soil due to different locations eluviation weathering， the influence of human activity and the degree of different level， the soil grain composition there is some 4 different soil layer， due to the different soil of rock， soil contains sand development of sandstone and mudstone limestone， development of viscous grain 5 the same soil types， different sub-types of soil particle composition is different， but the trend is Keywords: rock into the soil， The soil profile， Grain grade， Determination
The grain size composition of the soil affects the soil physical and chemical properties， this is the hydrometer method using several rocks in the southwest area of soil (soil， lime soil， volcanic ash soil) of the grain size were measured and The following conclusions:⑴ South West Rocks into the soil， purple soil， limestone soil and volcanic ash soil particles share of major sand， clay， silt smaller ⑵ between the different layers of the same soil， due to deposition and other effects of leaching and soil composition on the lower classes there are some differences in grain size， black limestone soil of sand and clay content with depth was The volcanic ash soil sand and clay content with depth ⑶ different locations the same soil as weathering， leaching and the impact of human activities to varying degrees， the composition of the soil there are some differences in grain ⑷ the same layers of soil， due to different soil-forming rock， sand soil developed over sandstone， limestone， shale rock clay and ⑸ the same soil types in different subgroups of the soil， particle composition is different， but similar
The soil grade composition is affecting the soil physics and chemistry nature， this article is uses the hydrometer method becomes the soil to southwest area several kind of crags (purple ochre， calcareous soil， volcanic ash soil) the grade to carry on the determination Draws the following conclusion: ⑴The southwest area crag becomes the earth， purple ochre， the calcareous soil and volcanic ash soil's pellet sand grains account for the proportion to be big， the clay， the silt account for the proportion to be ⑵Between identical soil different soil layer， as a result of function and so on leaching deposition influences， on the soil lower level grade composition existence certain difference， rendzina's sand grains and the clay content increases along with the depth But volcanic ash soil's sand grains and the clay content increase along with the depth ⑶Because the different place identical soil the weathering， the leaching function and human activity's influence is different， soil separates composition existence certain ⑷Different soil identical soil layer， because becomes the earth the rock to be different， sandstone growth soil sandy many， the limestone， the mudstone growth's rock clay are ⑸The identical soil type different subgroup's soil， the granulometric composition is also different， but the general trend is

rather than Human beings show more respect to bees than to other animals， not for their diligence， but for their dedication to We live in a materialistic society and are trained from our earliest years to be We are taught early on to be materialistic and taught to consider things， or to be exact， money， “mine” or “yours” It seems impossible to live in the modern society without Money is even regarded as a symbol of wealth and social There is a saying that goes， “money makes a mare ” People seem to look more highly upon ones' possession of money rather than one's dedication to Some people pursue their own personal benefits at the cost of Some people always ask for payment after their “dedication” Dedication and expecting nothing in return is the highest level of Lei Feng's spirit of

译文：我们从这幅画中可以看到，一群蜜蜂飞来飞去忙着采蜜，它们不是为了自己享受，而是为了给人类酿造甜美的蜂蜜。比起其他动物人们更加尊重蜜蜂，不是因为它们的勤劳，而是因为它们的奉献精神。我们生活在一个物质社会，从小就受到了贪婪索取的训练。早期物质方面的教育使我们从小就对 “你的”和“我的”东西，或者具体一点，也就是金钱，泾渭分明。在当今社会，没有钱是不能生存的。金钱甚至被看作是财富和社会地位的象征。俗话说，“有钱能使鬼推磨。”人们似乎更看中一个人财富的多少，而不是这个人对社会贡献的大小。有些人为了追求自己的利益而不惜牺牲他人的利益。有些人在所谓的“奉献”过后总是索取回报。只奉献不求索取才是奉献的最高境界。雷锋的奉献精神就是一个典型的例子。蜜蜂用它们的辛勤劳动为人类酿造了甜美的蜂蜜，却从不求索取，不图回报。这正是人们尊重蜜蜂的原因。奉献能给我们带来幸福和成就感。奉献于社会和人民的那些人也一定会从奉献中得到极大的快乐。
