The type, initial feeding time and concentration of precursor for HV unit formation had great effects on PHBV production in shake flasks. Propionate was selected as the better precursor for HV fraction than valerate after comprehensive survey of these two precursors. The suitable PHBV shaking-flask culture conditions were obtained through the analysis of PHBV fermentation process, the investigation of several factors by using RSA method and the fed-batch experiments. Cell dry weight, PHBV content, PHBV concentration, HV fraction and yield coefficient of HV unit to propionate were 27. 7g/L, 80.7%, 22. 4g/L, 16. 1mol% and 0.50g/g, respectively.

在共聚物PHBV的摇瓶发酵过程中，PHBV中HV组分形成的前体物质的种类、初始加入时间以及加入量是影响PHBV发酵过程的重要因素；在综合比较丙酸和戊酸这两种前体的基础上，选择丙酸作为HV组分合成前体较适宜；通过对PHBV发酵过程曲线分析、影响PHBV发酵指标的各因素的响应面分析以及摇瓶发酵补料试验，得到了较适宜的PHBV摇瓶发酵补料条件，在此条件下，细胞干重、PHBV含量、PHBV浓度、HV组分含量和HV组分对丙酸的产率系数可分别达到27.7g/L、80.7％、22.4g/L、16.1mo1％和

For assisting identification of crude drug Herba Dendrobii. Methods Morphological and histological studies were carried out on 11 medicinal plant roots in Dendrobium Sw. by microstructural observation. The 11 species were divided into three groups according to their stem morphology: a pair fleshy-stem group, including D. chrysanthum, D. crepidatum, D. primulinum, D. hercoglossum, and D. crystallium; b thick-and rigid-stem group, including D. fimbriatum and D. aurantiacum var. denneanum; c node-or inter- node- bulgy-stem group, including D. findlayanum, D. gratiosissimum, D. pendulum, and D. wardianum. The surface descriptions of velamen were conducted for D. fimbriatum and D. aurantiacum var. denneanum which are similar in characters of cross section.

We had enough of sympathy for fifty years;it nev-er brought us anything;and we would rather havean angry man going to the government and saying,my business is interfered with and I won't submitto its being interfered with any longer because youwon't give women the vote,than to have a gentle－man come onto our platforms year in and year outand talk about his ardent sympathy with woman suffrage.

她所需要的是办成某件实事，至于办成这件事是出于同情还是恐惧，还是由于人们企盼重享安宁而不在这方面再有烦恼，只要这件事已办成，就都没有什么特别要紧的了。50年间我们得到过足够多的同情，却从未因而得益；与其看到一位绅士年复一年地走上我们的讲台侈谈他对妇女选举权的热忱，还不如看到一个愤怒的男人去对政府说，我的生意受到了阻碍，我不能容忍由于你们不给妇女以选举权而使我的事业继续受到干扰。

Not much live bait fishing is done at all for yellowtail in Japan, although I have caught them on aji that I caught on sabiki rigs and then cast back out on live bait hooks on heavy line.

The effects of 20~100 mg/L MS-222,Tricaine Methanesulphonat,were tested at water temperature 15~25 ℃ on two species of sturgeons,Acipenser sinensis and A.schrenckii.

以20~100 mg/L的MS-222在水温15~25℃条件下对中华鲟和施氏鲟(A.schrenckii)的麻醉效果进行试验，中华鲟或施氏鲟分别达到不同程度的麻醉状态甚至出现死亡。30~40 mg/L的MS-222具有较好的麻醉效果，鱼的活动量明显下降，可保持镇静并维持身体平衡和正常体位，麻醉48 h后，在清水中数分钟内可恢复正常游动状态，适合于长途运输。50~100 mg/L的MS-222对中华鲟和施氏鲟具有较强的麻醉作用，适合于进行短时间的操作，如捉拿、称重、测量、外科手术、体外标记等。

The main achievements of the project are as follows: 1 the hypothesis that a decrease in seed mass causes an increase in mean dispersal distance has been tested based on the experiments of weed dispersal by wind. The experimental results partly support the hypothesis. The results will help farmers to make an optimal strategy of weed control; 2 a statistic method for inferring probabilistic distribution function of a random variable has been developed, by which probabilistic distribution functions of weed species dispersal have been determined; 3 the reproduction structure of Bromus sterilis has been studied; 4 a more complex CA model with 25 neighborhood cells were built, which can simulate spread of a weed population. This work promotes developments in both theory and application of CA models; 5 the "mean law" in weed control has been proposed. Accordingly, the algorism of patch spring may be calibrated; 6 the "patch" and "true patch" have been mathematically defined so that herbicide can be efficiently applied; 7 simulation validates that initial configurations of weed will affect dispersal of its population and strategies of controlling it, or its distribution patterns affect its dispersal progresses.
