In addition, the key steps and main features of the improved CTAB method are discussed.

A modified CTAB was developed to isolate DNA of Chinese cabbage from each line and parents.

提取大白菜总基因组DNA以改良CTAB法为宜.

Methods: The improved CTAB DNA extraction method.

方法: 改良CTAB法.

And the DNA concentration is higher than improved CTAB method.

而CTAB法抽提银杏胚乳DNA纯度较高,含杂质少.

The results showed that the ratio of CTAB/ TPAOH, composition of microemulsions system, oil content and the silica sources had great influence on the crystallization of obtained zeolites and the final morphology.

研究结果表明，CTAB/TPAOH比值、微乳液组成、硅源及油相含量都在很大程度上影响着沸石的晶化度和最终形貌。

The quality of TPAOH solution was one of the most important factor in the synthesis of TS-1 zeolite.

四丙基氢氧化铵（T PAOH）的品质是影响TS-1分子筛性能的最重要的因素之一。

Film thickness, morphology and orientation could be effectively controlled by adjusting crystallization time and times. The best molar composition of Ti/ Si, H2O/ Si and TPAOH/ Si in mother liquid was 0.02,250 and 0.35.

改变晶化时间和次数可有效调节膜厚度、形貌和取向；母液中最优Ti/Si、H2O/Si和TPAOH/Si摩尔比为0.02、250和0.35。

Results showed that TPAOH was easy to be decomposed ton-tripropylamine and propanol.

结果表明，TPAOH容易分解为三正丙胺和正丙醇；

Such arrangements, typical of foreign JVs in China, work fine for routine complaints, such as one party seeking damages from the other for a faulty product.

这在中国的中外合资企业中是一种典型的做法，对于日常申诉的解决还是管用的，比如一方寻求另一方就某种问题产品给予损害赔偿。

However, cultural difference is not the hindering factor to performance; in fact, heterogeneity provides JVs with better outcomes.

但文化差异并不是阻碍业绩的因素，相反异质性特征会给合资企业带来更好的结果。

The main results were as follows: 1. Observed a great deal of JWB plantlet, we found that, small leaves, short burl distance, thin stem, more axillary bud, stipule thorn became leaves bigger, is the JWB representative symptom;

1对枣疯病组培苗的观察结果发现，叶片小，节间距短，茎细，腋芽萌发多，托时刺退化成的小叶大是组培苗发生枣疯病的典型症状；

Selecting cultivars with high resistance was regarded as the most powerful method to eradicate JWB and had made some progress, but the mechanism of resistance was still in its beginning stage.

抗枣疯病品种的选育已经取得了一些进展，但抗病机制研究尚处于起步阶段。

The Jujube witches'broom disease ( JWB) caused by phytoplasma has brought much economic damage to jujube production in our country.

由植原体引起的枣疯病在我国分布普遍，危害严重，使我国的枣树生产遭到极大的经济损失。

The authors assume that readers have a basic knowledge of both JSF and JWL.
