From [1], Every transition function is a positive strongly continuous semigroup of contractions on l\, but it isnt a strongly continuous semigroup on l_∞- In fact, the sufficient and necessary condition for a transition function to be a strongly continuous semigroup on l_∞ is that the q—matrix Q is an uniformly bounded q—matrix on l_∞- This is the trivial case.
由Anderson[1]知道转移函数P是l_1空间上正的强连续压缩半群,但P一般来说不是l_∞空间上的强连续半群,而P是l_∞上强连续半群的充要条件是q—矩阵Q是l_∞。

We first show some properties of such operators and give an explit description about the image of a linear bounded operator on a linear normed space. Then based on these results, we show the mean ergordic theorem on a C*-bial-gebra and get a sufficient and necessary condition for a linear functional to be Haar measure. Finally we discuss the sufficent conditions for the existence of Haar measure on C*-bialgebras.

Beauv effectively, and bensulfuron methyl (30g/hm^2) applied 6 d after rice transplanting could significantly reduce the plant numbers and biomass accumulation of difformed galingale (Cyperus difformis L.) and procumbent falsepimperne . The control efficiency of Huakangcao 78 and Yangdao 6 were 89.16% and 81.86% on barnyardgrass dry weight respectively 50 d after the rice transplanting, 83.56% and 84.93% on difformed galingale dry weight, 95.22% and 88.04% on procumbent falsepimperne dry weight. As a whole, the total dry weight control efficiency were 87.68% and 82.69% on above weeds correspondingly. Moreover, the grain yield of Huakangcao 78 and Yangdao 6 under the condition of 10cm depth water and herbicide application increased 40.33% and 21.36% comparing those under the treatment of 5cm depth water and no herbicide application respectively.

The method on trans fatty acids analysis in food is very important. The effects of methylate sodium, potassium hydroxide, sulfuric acid and boron trifluoride in methanol and their different concentration and dosage on TFA analysis were studied. The chromatographic condition and the influence of time and temperature on the esterifation of TFA using boron trifluoride in methanol were optimized. A method for analyzing TFA were established by GC based on boron trifluoride in methanol and RT-2560(100m×0.25mm×0.2μm) capillary column.
