The tree diameter at breast height and crown length can be used to predict the size and location of mean knot diameter in a whorl.A linear mixed model expressed as function of tree and knot variables such as HK、RKD、KD and DBH was used to predict sound knot length,and a log-linear mixed model using RKD and DBH as variables was used to describe loose knot length.4.A knot has four development phases:from the birth of a branch to its growth cessation,from growth cessation to death,form death to occlusion and form birth to occlusion.The numbers of annual rings in four periods,as well as the stem width of respective zones were used as dependent variables predicted by models expressed as function of tree variables and knot attributes.5.Using the data of diameter out side bark of 15 relative heights along the step,the best taper equation for Larix olgensis was established.

Oh, perhaps to his own too much pressure on it, yes ah, the Shanghai is full of people looking forward to countless people and reverie of the city, on a subway will be able to feel like me who are trying to fight the Workers, used to get up very early (not hard, afraid to go to work late because of salary deduction), used to the unit within the Office of the breakfast (because of the way, all vehicles coming and going, the crowd rushed, there is no way you To free a hand to feed the stomach) used to join the crowded elevator, used to listen to the words do not know how to Shanghai ......
不敢想!唉,也许是自己给自己的压力太大了吧,是啊,上海这座让人充满无数憧憬并且让人遐想的城市,一上地铁就能感受到那些和我一样正在努力拼搏的打工者,习惯了很早起床(不是因为勤快,因为怕上班迟到扣薪水),习惯了在单位的办公室内早饭(因为路上、车上全是来来往往、急匆匆的人流,根本没有办法让你腾出一只手来喂饱肚子)习惯了一起挤电梯、习惯了听不大懂得上海话。。。。。。

through text analysis,this paper examines the syntactic and morphological means typically employed in introducing topics into chinese and english texts and their relations to discourse anaphora.we find that in both chinese and english the most important means for introducing the most important and accessible topics into discourse are the indefinite nps used as objects in existential-presentative sentences,and that the indefinite demonstrative adjective zheme and this can be used as an additional means to emphasize the importance of the entity introduced.however,the two languages differ in that,in english texts,apart from the above-mentioned linguistic devices,definite nps functioning as indirect objects and names functioning as subjects also tend to be used to introduce relatively important topics,and the emphatic one,in contrast to the indefinite article "a",can be used as another linguistic means to give additional emphasis on the relative importance of the topic introduced.
摘 要:本文以民间故事为语料,分析和研究了英汉篇章中话题引入的句法和形态手段及其与篇章回指的关系。我们发现,两种语言的主要相似之处为:1用作存现宾语的无定名词短语是引入篇章中最为重要和最为可及话题的主要手段;2英汉无定指示形容词this和&这么&可用于进一步强调所引入话题的重要性。两种语言最主要的差别是:1在汉语中,存现结构中的无定名词短语似乎是引入重要篇章话题的唯一形态句法手段;而在英语中,除此之外,用作间接宾语的有定名词短语和用作主语的专有名词也可以用于引入一个相对重要的篇章话题。2在英语篇章中,另有一个标示重要话题的附加手段,即以one代替a,以便进一步强调所引入话题的重要性。

So in this paper based on the characteristics and the optimum state theory of the vehicle, some kinds of control schemes are compared and discussed, and the fuzzy PID control scheme is adopted at last. The relation between air-cushion pressure and fan rotational speed on the optimum driving state is studied. The cushion pressure is used as controlled variable and the fan revolution is used as regulated variable. And transducer and fan motor are actuators.Based on the structure and operating properties of half-tracked air-cushion vehicle, the control system scheme and structure are presented. A control scheme using the self-tuning PID fuzzy logical controller is adopted. Fuzzy rules are set up and some researches have been done for fuzzy tuning method. At the same time the real-time measurement scheme by computer control is proposed, and electric circuits are designed. In the control system of half-tracked air-cushion vehicle cushion pressure P〓 is used as controlled variable and the fan speed n〓 as regulated variable.

But it demands the higher computational accuracy. Time-dependent LU-SGS method and close coupled full implicit finite volume scheme are used. The AUSMPW+ based on the three-order MUSCL difference scheme is used for the inviscid operator, and the maximum eigenvalue splitting method is used to convert matrix operation to algebraic operation in order to shorten the computing time.
