1) projection coverage of woody and herb layers
冠层投影盖度
2) Canopy cover degrees
冠层覆盖度
1.
Canopy cover degrees had a outstanding positive linear correlation to tuber expansive speeds.
根系拉力与冠层覆盖度及块茎产量均呈极显著正相关,即根系拉力越大,冠层越旺盛,块茎产量越高。
3) total coverage
总投影盖度
1.
During a growing season,the total standing crops,total coverage and average heights of plant community,as well as soil physical and chemical characteristics in different grazing units ofstipa baicalensissteppe,Hulunbeir,were compared and analyzed.
在一个生长季内,比较分析了贝加尔针茅草甸草原不同放牧强度地段(非牧段,轻牧段,中牧段和重牧段,以放牛为主)植物群落的总地上现存量、总投影盖度、平均高度和土壤理化性质的变异。
4) foliage projective cover
叶片投影盖度
1.
In this paper,the seasonal and annual growth,foliage projective cover(FPC),evaporative coefficient(k),and net primary productivity(NPP) of 7 types of grasslands in North China were simulated by using a simple model based on well established ecological processes of water balance and climatic data collected at 460 sites over 40 years.
采用基于水分平衡过程的、简单的植物群落模型,利用460个气象站40年气象数据的月平均值,模拟中国北方7种草地类型的季节及年生长、叶片投影盖度(FPC)、蒸发系数(k)及净第一性生产力(NPP)。
5) crown projection
树冠投影
1.
In the paper the crown projection table, paper pulp utilization ratio table and bark deduction table of E.
尾叶桉(U_6)无性系在我国南方各省(区)、市发展快,种植面积约15万hm~2,雷州尾叶桉(U_6)无性系立木二元材积表已刊载于《桉树科技》2005、1期,为了满足生产、科研、森林调查的需要,现利用编制雷州尾叶桉(U_6)无性系立木二元材积表的1059株样木原始资料加编雷州尾叶桉(U_6)无性系树冠投影表、纸浆材利用率表和树皮率表,经检验精度可靠可供参考使用。
6) LPDOS
层投影态密度
补充资料:映像清晰度、投影清晰度
分子式:
CAS号:
性质:又称映像清晰度、投影清晰度。反映固体表面平整程度的相对性物理量,经常用于表征金属、塑料制品的表观涂装质量,用Dorigon鲜映度测定仪测定。例如以有底漆钢板涂装的A级表面为100,无底漆钢板的涂装表面可达96,聚氨酯RIM系统(无填料)涂装后DOI为95,添加22.5%云母片的聚氨酯RRIM系统涂装后可达94,而加有25%锤磨玻纤的聚氨酯RRIM系统仅78。
