生长标准的

Results The study showed that all the nutrients intake in 24 hours were more than 100% of the RNI except energy,calcium and zinc, and vitamin A intake of the children in Xi'an were less than 90% of the RNI. No statistical significant difference was found in the prevalence rates of lower weight, retardate development, emaciation, overweight and obesity between ages, regions and genders, and the prevalence rate was 0, 4.2%, 0, 3.3% and 10.0% respectively. Conclusion There are some differences between the preschool children investigated in Beijing and Xi'an.

结果 除能量、钙、锌外，北京和西安幼儿园儿童24 h摄入的各种营养素均能达到参考摄入量标准的100%以上；但西安幼儿园儿童维生素A的24 h摄入量未能达到参考摄入量标准的90%。2地学龄前儿童低体重、发育迟缓、消瘦、超重和肥胖的检出率在年龄、地区和性别上差异均无统计学意义（P值均＞0.05），低体重、生长迟缓、消瘦、超重和肥胖的检出率分别为0，4.2%，0，3.3%和10.0%。

The WHO is still analysing the data and plans to launch the growth standards with some fanfare next year.

WHO还在分析这些数据，并计划在明年的某个时候隆重地推出新的生长标准。

Four of 15 cell lines derived from primary glioblastomas grew adherently in vitro and were driven by CD133 tumor cells that fulfilled stem cell criteria.

个源于胶质母细胞瘤的细胞系中有四个在体外呈附着生长，并受已达到干细胞标准的CD133阴性肿瘤细胞驱动传代。

Now, Flavonoids and ginkgolides were mainly extracted from the leaves of Ginkgo biloba., but the leaves often contain high content of corious and cereous, and the effective constituent is very different under the various conditions. In addition, the constituent of ginkgolides is very low in the leaves, and thus the quality of extraction is difficult to reach the international standards.

目前人们主要从银杏叶中提取银杏黄酮和萜内酯，但由于银杏黄酮和银杏内酯的含量很低，尤其银杏叶中最主要的有效成分银杏内酯B主要存在于根中，在银杏叶中含量极低(＜0.1％)，且是在生长状态的叶中含量最高，采叶影响树的生长；又因银杏叶中主要的有效成分受多种因素的影响又有很大差别，银杏叶革质化、蜡质化程度高，使得国内银杏叶提取物的质量很难达到国际标准。

According to the Wakitanis standard, the group A has the best plerosis effect on the repairing of articular cartilage defect compared with the other groups. It had been proved to have the significantly difference from all the control groups by statistics disposal.

按照Waki tani标准修复关节软骨效果由好至差的顺序为有生长因子BMP一2的细胞改良FG支架复合物组、无生长因子的细胞改良FG支架复合物组、单纯改良FG支架、空白对照组。

In recent years, LMS technique outstands in mushrooming methods about fitting percentile curves, which had been widely used to establish normal references in many countries and areas worldwide, mainly on indicators as height, weight and BMI.

近些年关于拟合百分位数曲线标准的文献层出不穷，偏度均值变异系数法技术可谓一枝独秀，目前广泛用于许多国家及地区的生长发育百分位数标准曲线制订，主要应用于儿少身高、体重及BMI领域。

According to its supporters, bamboo's fast growth means it sequesters more carbon than slower-growing trees, thus qualifying the flooring and plywood for a "rapidly renewable" materials accreditation under the Leadership in Energy and Environmental Design green building rating system see " MisLEEDing?"

支持者认为，竹子快速生长的特点就意味着它的固碳量比生长慢的树木要多得多，因此在& LEED 绿色建筑评估标准&的认证下，竹制地板和夹板被认证为&快速再生材料&。
