半连续的

According to [2], we know that if X is a reflexive Banach space and T is a strongly continuous semigroup on X with the infinitesimal generator A, then the adjoint semigroup T~* is also a strongly continuous semigroup on X* and its infinitesimal generator is A~*, the ajoint operator of A.

由文献[2]我们知道，如果X是一自反Banach空间，那么X上强连续半群T的对偶半群T~*也是X~*上的强连续半群，并且其无穷小生成元为半群T的无穷小生成元的对偶。

According to the data above, with the decrease in the renewal period, the NO3-N and PO4-P in the cultural liquid could not be consumed in time by the cells of P. cruentum, and therefore, more NO3-N and PO4-P were accumulated in the semicontinuous culture system.

根据上述数据，以减少续期期间，硝态氮和PO4 - P的文化液体不能及时消耗的紫球藻细胞，因此，更多的硝态氮和PO4 - P的积累的半连续培养系统。

On the other hand, such training was really hard-worked, working continuously from 8 am until 11pm every day. So that, at the end, almost all the people didn't want to stay there any more. We took the train TGV at 11:00 on 27th, Sep., arrived at Paris after four and half hours. When I entered in my flat, I saw my wife was cooking bouilli which is my favorite. How lucky am I!

从另一方面说，这个培训的工作量大的惊人，每天从早上8点一直到晚上11点，连续的工作，以至于到最后一天的时候，几乎所有的人都表示，再也不愿意在这里多待一天。27日中午11点的TGV，四个半小时到巴黎，回到家老婆正在给我做最爱吃的红烧肉，甚是幸福！

The distillation column with a single photochlorination reactor was built in this paper, which is used in the laboratory study. In light initiation, the semi-continuous operation was applied to study the influence of the chlorine flow, the reflux and the height of the packing on photochlorination of acetic acid. Crude MCA with a purity of 90% or more was attained and the feasibility of this technology was proved.

本文建立了适合实验室研究的背包式光氯化反应精馏耦合装置，采用半连续操作的方法，在光引发条件下，考察了氯气流量、回流量和填料高度对乙酸光氯化反应的影响，得到了含量达90％以上的氯乙酸粗品，证实了工艺的可行性。

VOA的SpeciaI English节目一般历时半小时,依次为10分钟的News,接着为5分钟的Environment Report、A griculture Report、Science Report、Development Report、People in the News、Words and Their Stories,最后是15分钟的 This ls America、Science in The News、Ex ploration、The Making of a Nation

上述各种节目中，以News为最难，因为它覆盖范围广，政治、经济、军事、文化和科技等等，用词量比其他节目多，理解时需要各种背景知识。但是如果连续听，听懂前一天的内容后很利于听懂以后同一事件的消息。

In the finite element analysis, by adding individual beam elements to model the connector between top joints and chords in finite element model, based on the experimental model, the factors affecting the shape forming process of dome, such as the bending stiffness of duckbilled connector and the size of top joints, can be taken into account; A whole and continuous analysis method is put forward for solving the question of applying the member forces produced in the shape forming process to the finite element models of load analysis.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
