For a higher yield, the multibranch well bore should be perpendicular to the direction of maximum principal permeability, b. for a given coalbed methane reservoir, there is an optimal interspace, by which a bigger control area and the interaction among the branches can be obtained, and c. with the extension of the branch, gas yield becomes obviously higher, while the branch length should be an appropriate value on account of the influence of coal bed boundary and wellbore pressure drop. The research results have guiding significance for well pattern optimization and efficient development of coalbed methane gas.

结果发现：为了获得较高的产能，多分支井的井筒应垂直于最大主渗透率方向；对于给定的煤层气藏，存在一个最优的分支间距，既能保证较大的控制面积，又能保证分支间的互相影响；随着分支长度的增高，产气量也显著增大，但是考虑到煤层边界和井筒压降的影响，分支长度也应该有一个比较合理的值。

As CAAX-mimetics, 1, 3-dihydro-5-phenyl-2-H-1, 4-benzodiazepin-2-one was modified by linking carboxyl groups with various carbon through N-1 and C-3, 3-(imidazol-4-yl) propion amido group with different substituents was connected at C-7; In the synthesis of bisubstrate analogues, thiocarbamido compounds was alkylated by alkyl iodide and then hydrolyzed to give alkylthiol benzoate compounds.

As compared with the traditional irrigation-traditional fertilization, the following results of the improved optimized irrigation-optimized fertilization were obtained: significantly higher nitrogen use efficiency; the like tiller number per unit area, percentage of the tiller ear number/the tiller number, the ear number per unit area, the greatly reduced grain number per ear, and significantly heavier weight of 1, 000 grains; a trifle taller plants; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; almost the same LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; a little longer flag leaf, 2〓 leaf, 3〓 leaf (but the three leaves were shorter than those of the optimized irrigation-traditional fertilization) and shorter 4〓 leaf from top, a bit reduced total area of these leaves; almost the same leaf thickness, mean canopy leaf tilt angle, light extinction coefficient , ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and fair plant type; almost the same senescence process of flag leaf; and increased root amount in 0-120cm soil layer and smaller rate of progressive decrease of the root length density and root weight density with soil getting deep, which can strengthen the resistance to adverse conditions such as water stress in the later stage.

在优化水肥条件下，冬小麦总分蘖数、成穗率及单位面积穗数与传统水肥比较接近，但穗粒数显著减少，千粒重显著提高；株高稍有增加；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期LAI与传统水肥的LAI值基本吻合；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟所形成的干物质量增加；上三叶变长（但上三叶长度增加幅度小于优化灌溉-传统施肥处理），倒4叶变短，总叶面积略有减少；叶片厚度、冠层平均叶倾角、消光系数、冠层各层的透光率与传统水肥差异很小，株型较好；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层的总根量明显增加，上层根群和深层根群的差异最小，有利于提高小麦后期的抗逆力。

The boundary height of natural gas coming-up is accreting along with the reservoir temperature and pressure decreasing.

根据气体状态方程及天然气运移的动力学理论，推导出温度和压力降低前、后气体流速比方程，用其计算了不同储层中临界气体长度并分析不同储层中相同长度的气体在运移途中的变化规律。

None of the generated text is appended and length of this descriptor may be less than the maximum.

没有生成文本的追加，描述符的长度就可能小于它的最大长度。

Variation in hay, even in large (1 ton) bales, and no significant differences were seen

的代表性，即使是一吨一个的大捆，用长度为12英寸的取样器，与用长度为32英

Formal exploration and revisions were fluid and effortless: rather than drawing and measuring the length of each string, we sketched the qualities of the installation in general terms; the software then automatically generated the thousands of catenaries, computed their lengths, and prepared labels to locate each string once cut.

正式勘探和修订流体和轻松：而不是图纸和测量长度每根弦，我们描绘的素质安装笼统；然后，该软件自动生成的数以千计的catenaries ，计算其长度，并准备标签查找每根弦再次降息。

The research shows that: the nearest distance relates with a characteristic length charactering tissue when the measurement closing source, the width of detector can be decided by the characteristic length of tissue, and the number of detecting fiber may be estimated with the diameter of practical fiber.

研究表明，当需要在光源附近对组织进行测量时，最近的距离与描述该组织的特征长度有关，根据组织的特征长度可以确定探测器的大致宽度，并结合实际光纤直径估计测量光纤的数目。

For a ciphered packet, regardless of the length of the packet data bytes, the RC4 has a constant latency which will generate the excessively low throughput when the packet length is too short especially.

对於要加密的一个封包，不论封包长度为多少位元组，RC4有其一固定的延迟周期，此延迟会造成过低的资料吞吐量，尤其是当封包长度愈短时。

When decrypting the maximum length of the cipher text is the length of the modulus in bytes.
