Calcicole Describing plants that thrive on neutral to alkaline soils rich in calcium carbonate, i.e.

钙生植物：在富含碳酸钙的中性或碱性土壤中生存的植物。

A good balance between the dynamic property and the thermal-oxydative ageing property on the blend vulcanizates were obtained when curing system is SEV and the S/CZ/DM ratio of 1.5/1.5/0.5;There was a good balance among tensile strength and heat build-up and damping property on blend vulcanizes filled with moderate size carbon black;The mechanical properties of vulcanizate filled with N660/N330 and N660/N990 were medium between two carbon black filled individual.

补强填充体系对NR/ENR硫化胶的性能有较大的影响，选择粒径适中的炭黑品种N660作为补强剂，硫化胶在拉伸强度、疲劳生热和减震方面可以获得较好的平衡；N660/N330和N660/N990两种填充体系硫化胶的力学性能，基本上是单用一种炭黑所得硫化胶力学性能的加权平均；N660/白炭黑(40/20)和N660/碳酸钙(45/15)填充体系硫化胶的力学性能与相同用量下N660单用时的相当，而N660/陶土填充体系硫化胶的力学性能较差。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
