向日葵

The sunflower Alternaria black spot is a very important fungal disease, which was first reported in China during the 1960s. It is still a potential threat to sunflower production at present.

向日葵黑斑病是一种重要的真菌病害，我国于20世纪60年代首次报道，目前对向日葵生产仍存在巨大威胁。

A method for determination phenolic acid(chlorogenic acid and caffeic acid)in sunflower seed s by HPLC was described.

建立了测定向日葵籽中酚酸含量的高效液相色谱法，同时测定了部分向日葵品种中酚酸的含量。

More money than having a field of sun flowers or corn from which you can press oil.

需要的钱比拥有一块向日葵或玉米地要多，而你可以从向日葵或玉米地中榨油。

One of the critical points in the design process was when it was pointed out that the sun collection mechanic was hard to learn for players who had never played Real-Time Strategy games. These players would plant peashooters but not enough sunflowers, and often lose because of that. So we took the sunflower's price down from 100 to 50 (the cheaper price would encourage players to buy it over the peashooter). That one change required a rebalancing of the entire game, but it was well worth it.

在设计中很重要的一点就是我们当时对于向日葵的价格设定，很多没有玩过即时战略游戏的玩家不懂得资源的累积，他们往往会建造太多的豌豆射手而忽略去补充向日葵，最后因为资源不足而输掉了游戏，所以我们将向日葵的价格从100调整到了50（便宜的价格会鼓励玩家多多建造它，而不是把资源全部用来建造豌豆射手），虽然这只是我们关于游戏平衡性调整的一个例子，我们花了不少时间去调整游戏的方方面面，但事实证明还是值得的。

Thirdly, we also examine the effect of these extracts on maize seed germination rate, maize seeding height and fresh weight, and the results show that three extracts are safe to maize at the concentration of 1:20, with a inhibit rate under 4 %.We further identified and purified organic acids, alkaloids hydroxybenzenes and neutral materials from extract and examined their effects on Amaranthus retroflexus L. seeds.

实验结果表明在干样：水为1：50以内，这三种向日葵的叶片提取液对反枝苋种子萌发和幼苗株高、鲜重及出叶数的抑制效果都非常显著；随着提取液浓度的下降抑制作用也呈明显的下降趋势；通过实验数据比较，这三种向日葵叶片提取液对反枝苋种子萌发抑制和对反枝苋幼苗株高、鲜重及出叶数的抑制效果略有差异。

The sunflower is an annual plant in the family Asteraceae, with a large flower head.

向日葵，別名太陽花，是一種可高達3米的大形一年生菊科向日葵屬植物。

Then product between the plant height and stem-diameter of sunflower is marked as the integrated index and regarded as primary variable. Choosing water conter and EC as secondary variable, the integrated index of sunflower is estimated using the three variables CK method that is in the form of covariance function.

将向日葵株高与茎粗的乘积记为综合性指标并视为主变量，选取土壤含水率与EC值为辅助变量，分别运用CK法与普通克立格法(Ordinary Kriging，简记为OK法)对向日葵综合性指标进行预测研究。

In order to ensure the quantity and quality of sunflower, when sunflower acreage accounts for 10% of cultivated land area, the distance between apiaries is better no more than 2600 meter.

为了保证向日葵的产量和质量，在向日葵种植面积占耕地面积10%左右情况下，对向日葵进行蜜蜂授粉时，蜂场之间距离不宜超过2600 m。

Results showed that shoot biomass of H. annuus was significantly higher than that of R. acetosa and R. hastatus; among three plant species, 134Cs specific activity in shoots was the highest in H. annuus after 50 d-treatment, however after 70 d-treatment, that in R. acetosa was the highest. Bioaccumulation ratio reached 1.5, 1.4 and 1.3 in R. acetosa, R. hastatus and H. annuus after 70 d-treatment, and the former two plants kept with trend of continuously increasing. Three plants were resistant to 134Cs contaminated soil and capable of translocating 134Cs from soil to plants. Among them, H. annuus removed greatest 134Cs amount in the aboveground part during the experiment period, and R. acetosa, R.

结果表明，向日葵地上部生物量显著高于酸模和戟叶酸模；处理50d时，向日葵地上部134Cs比活度在3种植物中达到最高，而在处理70d时，酸模地上部134Cs的比活度达到最高；处理70d时，酸模、戟叶酸模和向日葵对134Cs的富集系数均大于1，分别达到1.5、1.4和1.3，且前2种植物继续保持快速上升的趋势。3种植物对铯污染土壤具有一定的忍耐性，并具有较强的从土壤向植物转移铯的能力；在本实验期内（70d）向日葵对土壤中放射性铯的剔除能力最强，而酸模和戟叶酸模则具有更强的铯转移能力。

But in the course of internationalization, they meet with misunderstanding and puzzlement.

许多企业已经意识到了这一点，但在国际化的进程中，仍存在一些误区与困惑。

Inorder toaccomplish this goal as quickly as possible, we'll beteamingup with anexperienced group of modelers, skinners, and animatorswhosenames willbe announced in the coming weeks.

为了尽快实现这个目标，我们在未来数周内将公布与一些有经验的模型、皮肤、动画制作小组合作。
