As investigated, the shape of the fruit was mainly rotundity, and the color of the fruit were red, black, yellow, mauve. Variation coefficient of mineral elements, which revealed wider variation range and rich genetic diversity. Among them, Fe, the content and the variation coefficient of which was the highest(2.12 mg·100g-1 and 26.99％), it has large potential for futher selection. Ripe fruit of 12 wild myrobalan plum seedlings were analyzed using head space-solid phase microextraction and gas chromatography-mass spectrometry. The results showed considerable genetic variations in these aspects: The total content of volatile components, the classes and contents of each compounds classes, the segregation ratio, and content of main components. There were 83 compounds in total belonging to 6 classes detected in 12 wild myrobalan plum seedlings, including esters, alcohols, ketones, aldehydes, heterocycle and Hydrocarbons. Among them, Formic acid, hexyl ester, the content of which was the highest(4.33 μg·g-1),was important character impact odors.

结果表明，①新疆野生樱桃李实生株系的果实形状主要为圆形，少数为椭圆形、卵圆形、卵形和宽卵形，果实颜色有黄色、红色、紫红色和黑色等4种类型，野生樱桃李果实纵径、横径、单果重、果形指数以及可溶性固形物含量均存在一定程度的变异，遗传多样性较为丰富，其中以单果重的变异系数最大(9.13 %)；②新疆野生樱桃李实生株系果肉组织的Zn、Ca、Mg、Mn、Fe及Cu等6种矿质元素含量变异丰富，其中以Fe元素的含量（平均值为2.12 mg·100g-1）和变异系数（26.99％）最高，进一步筛选高铁性状单株的潜力很大；③从新疆野生樱桃李12个实生株系中共鉴定出醇类、醛类、酯类、酮类、烃类及杂环类等6类83种挥发性化合物，各实生株系挥发性化合物总含量、挥发性化合物种类及其含量以及主要挥发性化合物分离比率与含量等存在广泛的遗传变异，遗传多样性较为丰富，其中以甲酸己酯含量最高（平均值为4.33 μg·g-1），是野生樱桃李果实香气形成的重要特征性化合物。

There are basically two types of tests that you can get, namely screening and comprehensive.

有基本上使用两种类型的测试，您可以得到，即筛选和综合。

In this paper, concentration of 300mg/L Naphthol Green-B dyes was used to be treated by white rot fungi. At first, the strain of pc5305 was to be screened for the best decolorization white rot fungus which used to treat Naphthol Green-B from the four different strains.

本文以300mg/L的萘酚绿-B染料为处理对象，首先从四种不同白腐菌中筛选出对萘酚绿-B具最佳脱色作用的pc5305，并对pc5305脱色萘酚绿-B的条件进行了优化。

Two molecular markers linking to flesh color of nectarine fruits, were screened from 340 RAPD primers.

经过对340条RAPD引物的筛选后，得到2个与桃果肉颜色性状连锁的分子标记s21-400和

The result indicates that:(1) the coefficients of variation of all strains' quality character are different, so it is effective to select qualitative character from the descendants;(2) the content of fat and content of water-soluble protein are remarkably negative correlation among variation strains.

结果表明：(1)所有品系的品质性状的变异系数差别较大，说明在后代中进行品质性状筛选是有效的；(2)突变品系内脂肪含量与水溶性蛋白含量呈显著负相关。

The way to use PMP to solve problem is a kind of sifting method:"If the control isreally an optimum one,then under the conditions stated beforehand,the needle variationmust not cause the index to have negative variation."

Pontryagin的最大值原理解决实际问题是筛选的方法："即如果是最优控制，那么其在满足约束条件的前提下，必须有进行针状变分不会造成指标泛函的变分为正。"

Here optimum'is reflected by theindex to be the smallestBut the controls through such sifting need not be real optimumones,because maybe there are other kind of variation or high order variation throughwhich the index have negative variation and the conditions are satisfied.

这里最优的意思是通过指标泛函最小来表示的但是这样筛选过的控制未必是最优的，因为还可能可以用其他方式的变分或高阶变分等来使约束条件不变而指标泛函的变分为正。
