The relates to the prevention of channel package losing in audio code transmission, featuring in the BCH encoding for each audio parameter for barrel shape displacement superposition, packing and channel transmission.

抗信道恶劣丢包伴随误码的语音编码传输方法属于语音编码传输抗差错技术领域，其特征在于，该方法在编码端对语音参数码流分组并对每个分组进行BCH编码，然后对信道编码后的数据分组进行桶形移位联合叠加，打包合路送信道传输。

The 20S catalytic core of the 26S proteasome has the shape of a barrel made of four rings which are composed of seven differentαsubunitsα_1-α_7 at two outer rings and seven differentβsubunitsβ_1-β_7 at two inner rings at which the catalytic sites locate. Three of theβsubunits contain proteolyses sites, which are sequestered in the hollow interior of the 20S particle. Substrates enter the 20S through a narrow channel formed by theβsubunits, whose N-termini, depending on their conformation, can either obstruct or allow substrate entry and thus function as a gate. This entry channel is narrow and only permits passage of unfolded, linearized polypeptides.

哺乳动物26S蛋白酶体是由一个20S催化颗粒(catalytic particle，CP)和两个19S调节颗粒(regulatory particle，RP)组成的ATP(adenosine-triphosphate，ATP)依赖性蛋白水解酶复合体。20S CP是26S蛋白酶体的催化核心，它是由4个圆环堆叠形成的桶状复合物，其中两侧外环每个环是由α_1-α_7亚基组成，两个内环每个环是由β_1-β_7亚基组成，4个环的中央形成一个狭窄的内腔。2个β内环形成了20S CP的催化中心空腔，其内壁为催化活性位点所在地；外侧α环中心的孔道是底物到达催化中心空腔的通道，一般被α亚基上的N末端所封闭，阻止胞内非目的靶蛋白进入20S CP内被降解破坏。

The multistage construction analysis method has been successfully used to simulate the whole erection process of a 102m-span barrel vault grid structure and a 118m-span double-layer spherical reticulated shell.

并运用多阶段施工全过程跟踪数值理论进行了两算例分析：某102m跨度大型柱面网壳结构的累积滑移施工与支架滑移施工的理论模拟，某118m跨度双层球面网壳结构悬臂施工的全过程理论分析。

According to the model, the deflection and main pre-brace parameters are illustrated with the Jinsong station of the tenth line in Beijing. It demonstrates that the curve shape of theoretical result, computing result and the on-set measure result are uniform in the main and the change law is similar; that the circumferential space of pipe-roof has a optimum value while satisfying the pre-brace function; that the relation between diameter of steel pipe and flexibility of barrel vault meets negative exponential function. And the diameter of steel pipe has a optimum value.

依据该模型，以北京地铁10号线劲松车站管棚支护为例，着重对管棚的挠度和主要支护参数进行的分析表明：理论结果与计算结果和现场量测结果的曲线形状基本相同，变化规律相似；在满足预支护作用的同时，存在相对较优的管棚环向间距；钢管直径与管棚挠度之间符合负指数函数关系，管径存在最佳值。
